increased risk of primary hypothyroidism in preterm infants.serum levels of thyroid stimulating hormone, thyroxine, triiodothyronine, free t4, thyroxine-binding globulin, reverse t3, and the tsh secretory areas and peak t3 after intravenous injection of 40 micrograms thyrotropin-releasing hormone were determined weekly from day 5 to 6 to 11 weeks of age in 42 unselected full-term and 61 preterm belgian infants. the results on day 5 indicated a progressive deficit of thyroid function related to the degree of prematurity. in 92 infants this deficit progres ...19846432991
decreased free fraction of serum thyroid hormones during carbohydrate overfeeding.the impact of the increased t3 production induced by overfeeding is likely to be lessened if overfeeding also decreases the free fraction of thyroid hormones. therefore, we examined the effect of 17 to 20 days of carbohydrate overfeeding of five men on total serum t4 and t3 concentrations, the free fraction of these hormones, and serum concentrations of thyroid-hormone binding proteins, tbg, tbpa, and albumin. total serum t4 concentrations were unchanged by overfeeding and total serum t3 concent ...19846433150
probing the infra-structure of thymidylate synthase and deoxycytidylate deaminase.methods are described for preparing and structurally analyzing two enzymes involved in the formation of dtmp, deoxycytidylate deaminase and thymidylate synthase. in the latter case, it has been possible through the use of recombinant dna techniques with an amplification plasmid to obtain sufficient amounts of the e. coli and t4-phage synthases to complete the entire sequence of both enzymes by employing a combination of protein and dna sequencing methods. a comparative analysis of the l. casei a ...19846433661
changes in circulating iodothyronines in diabetics with various degrees of metabolic control.plasma tsh, total and free t3 and t4, reverse t3, blood ph, hbalc, ketonuria and glycosuria were evaluated in 8 subjects with diabetic ketoacidosis, in 54 diabetics of group 1 and group 2 without severe metabolic derangement and in 10 control women. the diabetics with ketoacidosis showed before intensive therapy low t3, total and free, and high reverse t3 concentrations as compared to controls (unpaired t-test, p less than 0.001). after one day of intensive therapy the decrease of hyperglycemia ...19846433942
plasma concentrations of luteinising hormone, follicle stimulating hormone, androgen, growth hormone, prolactin, thyroxine and triiodothyronine during growth and sexual development in the cockerel.changes in concentrations of plasma luteinising hormone (lh), follicle stimulating hormone (fsh), androgen, growth hormone (gh), prolactin (prl), thyroxine (t4) and triiodothyronine (t3) were measured during growth and sexual maturation in broiler cockerels reared in continuous light to 7 weeks and 14 h light/d thereafter. concentrations of lh and fsh began to increase between 13 and 15 weeks, while those of androgens increased between 16 and 17 weeks. fsh concentration increased faster than tha ...19846434159
hypothalamo-adenohypophyseal-thyroid interrelationships in the chick embryo. vi. midgestational adenohypophyseal sensitivity to thyrotrophin-releasing hormone.the functional abilities of 9.5-, 10.5-, 11.5-, and 12.5-day-old chick embryos to respond to exogenous thyrotrophin-releasing hormone (trh) were evaluated by means of changes in plasma total thyroxine (t4). t4 concentrations were determined 3.0, 6.0, 12.0, and 24.0 hr after trh treatment. the data of the present investigation show that chick embryo adenohypophyseal sensitivity to exogenous trh, as evidenced by changes in plasma t4 levels, increase during the 10.5- to 12.5-day incubation interval ...19846434370
low thyroxine levels in some hyperprolactinemic patients due to dopaminergic suppression of thyrotropin.the serum free t4 index (ft4i) was at or below the lower limit of normal in 8 of 55 unselected patients with hyperprolactinemia. serum levels of t3 were normal and none of the patients had clinical evidence of hypothyroidism. in patients with low ft4i the serum tsh was within the normal range and tsh was released normally after administration of trh, indicating normal pituitary tsh reserve. serum tsh also increased after administration of the dopamine antagonist domperidone. the tsh response to ...19846434574
thyroglobulin release after graded endogenous thyrotropin stimulation in man: lack of correlation with thyroid hormone response.the serum thyroglobulin (tg), t3, and t4 responses to graded endogenous tsh stimulation were examined in 30 normal subjects for up to 96 h after trh administration. increasing tsh rises were elicited by trh administration as follows: 1) 500 micrograms iv as a single bolus in 10 subjects [mean peak serum tsh, 14.3 +/- 1.8 (se) microu/ml]; 2) 1000 micrograms infused iv in 2 h in 10 subjects (mean peak tsh, 25.5 +/- 2.6 microu/ml); 3) 40 mg orally in 10 subjects (mean peak tsh, 27.5 +/- 3.0 microu/ ...19846434589
[hypotheses on the validity of the radioimmunologic measurement of ft4].in patients undergoing long-term thyroid hormone therapy with constant doses the results of ft4 concentrations measured by radioimmunoassay (ft4-amerlex) were compared with calculated ft4 values and related to total thyroxine, serum tbg levels, respectively t4/tbg, to control the validity of radioimmunologic ft4 measurements for clinical routine diagnostic purposes. based on mathematical analyses on the interdependence of these values the following principles were confirmed: free thyroxine measu ...19846434795
the distribution of thyrotropin-releasing hormone (trh) in the rhesus monkey spinal cord.the distribution of thyrotropin-releasing hormone (trh) in the rhesus monkey spinal cord was studied using a highly specific antibody to trh and the indirect peroxidase-antiperoxidase technique. trh-positive fibers were found at all levels of the spinal cord and were in greatest concentration in the ventral gray, intermediolateral column and central gray. all motor nuclear groups in lamina ix of the ventral gray were innervated by trh, frequently in close association with perikarya of alpha-moto ...19846435101
seasonal variations of total and free thyroid hormones in healthy men: a chronobiological study.the seasonal variations of iodothyronines and tsh serum concentrations were evaluated in 24 healthy subjects of both sexes. using a 12 month cosine function, a significant circannual rhythm was found in t3, t4 and free t4 whose maximal values were found in september for t3, in august for t4 and in october for free t4. no significant seasonal variations in free t3 or tsh were found. some circannual but not sinusoidal changes were found for reverse t3 and tbg. a positive linear correlation between ...19846435369
endocrine involvement in children with beta-thalassaemia major. transverse and longitudinal studies. i. pituitary-thyroidal axis function and its correlation with serum ferritin levels.thyroid function was investigated by a trh test in 24 clinically prepubertal children, 3-15 years old with beta-thalassaemia major; in 7 of them the test was repeated once and in 2 twice at intervals of at least 12 months. basal t4, t3, tbg and tsh levels and the tsh levels during a trh test were determined and correlated with age and serum ferritin levels. basal serum t4, t3 and tbg levels were lower and serum tsh levels were higher during the test and in the basal state in thalassaemia major c ...19846435370
thyroid hormone concentrations and free thyroxine status in neonatal venous and capillary serum pairs.the levels of thyroid hormones in paired venous and capillary serum samples taken from 68 healthy full-term neonates were determined by radioimmunoassay. compared with capillary values, total thyroxine (t4), thyrotropin (tsh) and thyroxine-binding globulin (tbg) each showed a significant decrease in venous serum. the mean venous and capillary concentrations of tri-iodothyronine (t3), reverse tri-iodothyronine (rt3) and free thyroxine (ft4) were not significantly different; however, in each case ...19846435500
thyroid status in patients after acute myocardial infarction.subjects followed serially after acute myocardial infarction demonstrated a rapid and sustained fall in serum total tri-iodothyronine (t3) concentration and a rise in reverse tri-iodothyronine (rt3) concentration. there was a transient fall in total thyroxine (t4) concentration. thyroxine binding globulin (tbg) levels were unchanged after acute myocardial infarction but prolonged falls were observed in thyroxine binding prealbumin (tbpa) and albumin concentrations. in contrast to the fall in tot ...19846435938
influence of chronic thyroxine treatment on plasma hormone and metabolite concentrations and on responses to insulin, glucagon and thyrotrophin releasing hormone in adult sheep.four adult sheep fed twice daily were given daily subcutaneous injections of saline for four weeks, followed by a similar period of daily l-thyroxine (t4) injection (1 mg/day). t4 treatment increased basal plasma concentrations of t4, triiodothyronine (t3), insulin and glucose, together with t3-uptake and the free thyroxine index, while cholesterol and urea concentrations decreased. t4 treatment reduced the rise in prolactin levels after the morning meal. thyrotrophin releasing hormone (trh) inj ...19846436158
cisplatin and full dose irradiation for patients with invasive bladder carcinoma: a preliminary report of tolerance and local response.twenty-seven patients with invasive bladder carcinoma (clinical stages t2 to t4) who were not candidates for cystectomy were treated by transurethral resection, cis-diamminedichloroplatinum (cisplatin) and full dose radiotherapy according to protocol 8 of the national bladder cancer collaborative group a. nausea and vomiting occurred in 74 per cent of the patients but were mild in 41 per cent. maximum followup was 27 months and during that time 3 significant toxic reactions occurred: renal failu ...19846436510
influence of clofibrate on thyroid hormone and muscle protein turnover.clofibrate, a hypolipidemic agent, has been shown to increase muscle protein degradation. the possible role of thyroid hormones in this phenomena was examined. clofibrate treatment of rats for 2 weeks resulted in a significant decrease in total thyroxine and triiodothyronine levels in serum. reverse t3 and resin uptake values remained unchanged. when exogenous thyroxine was co-administered with clofibrate, serum tsh levels were suppressed, but the increased muscle protein degradation was not rev ...19846436638
thyroid hormone levels in human breast cyst fluid.radioimmunoassayable levels of total and free 3,5,3'-triodothyronine (t3) and thyroxine (t4), thyroid stimulating hormone (tsh), thyroxine binding globulin (tbg) and prolactin (prl) were measured in a series of samples of breast cyst fluid (bcf) aspirated from 73 pre-menopausal women with gross cystic disease of the breast and in coincidental blood samples. in bcf free t3 and free t4 were consistently higher than in plasma (p less than 0.001) as was also total t3 in the majority of cases (p less ...19846437106
effect of danazol on thyroid function in postmenopausal women.during treatment with danazol the serum concentration of thyroxin-binding globulin (tbg) decreases. this effect is probably a direct effect on tbg production at the cellular level. in order to exclude an indirect effect on tbg production via the well known suppressing effect of danazol on serum estrogen concentrations, the following study was performed. twelve healthy female volunteers, who were at least 3 years past the menopause and with serum-estradiol levels below 100 pmol/l, were treated wi ...19846437126
altered responses of prolactin, luteinizing hormone and follicle stimulating hormone secretion to thyrotrophin releasing hormone/gonadotrophin releasing hormone stimulation in cyclical mastalgia.a generalized abnormality of hypothalamopituitary function was found in 17 patients with cyclical pronounced mastalgia compared with 11 controls by using a combined thyrotrophin releasing hormone and gonadotrophin releasing hormone test. the release of prolactin, luteinizing hormone and follicle stimulating hormone was significantly greater in cyclical mastalgia patients than in controls. basal thyrotrophin, t3 and t4 levels were within the normal range in both groups indicating normal thyroid s ...19846437468
familial growth retardation with isolated thyroid-stimulating hormone deficiency.three brothers with isolated thyroid-stimulating hormone (tsh) deficiency were observed at ages 17, 15, and 10 years. they suffered from severely retarded growth, with a marked retardation in bone maturation. their serum t4, t3, and tsh levels were low. serum thyrotropin-releasing hormone (trh) concentration was normal. no increases in tsh levels were elicited during the trh test. the other pituitary hormones, adrenocorticotropic hormone, growth hormone, follicle-stimulating hormone, luteinizing ...19846437722
ethanol inhibition of pituitary-thyroid axis: an effect secondary to nutritional deficiency.ethanol as either 20% or 36% of total calories in a lieber diet was administered to male rats. at these concentrations, ethanol consumption relative to body weight did not differ. pair-fed controls were restricted to the amount of calories consumed by rats given ethanol. under these conditions, a direct effect of ethanol on the hypothalamic-hypophyseal-thyroid axis could not be demonstrated. there were no differences between pair-fed control and ethanol treated rats in serum or pituitary tsh, ts ...19846437803
[local mitomycin-c therapy of infiltrating bladder cancer].adjuvant local chemotherapy for superficial cancer of the urinary bladder (ta-tis) is meanwhile performed on a nearly standardized level. the indication for infiltrating tumours (t1-t4) however is controversial. the prevention of tumour cell implantation which is promoted by transurethral resections is advantageous. on the other hand a curative effect cannot be expected from local chemotherapy in infiltrating tumours. the long-term results of adjuvant local chemotherapy in 86 patients with infil ...19846437950
effect of metergoline on prolactin, follicle stimulating hormone, luteinizing hormone and thyroid stimulating hormone response to trh and lhrh in normal men and women.metergoline, a prolactin (prl)-lowering drug with an antiserotoninergic activity, is known to restore menstruations and fertility in hyper-prl patients even when prl levels are not normalized. this suggests that metergoline might also affect gonadotropins release. in a double-blind cross-over study in 8 normal males, repeated administration of metergoline enhanced the lh response to lhrh and reduced the prl response to trh; for females, three different tests were performed on days 5, 8 and 21 of ...19846437954
effect of non aromatizable androgens on lhrh and trh responses in primary testicular failure.we have assessed the gonadotropin, tsh and prl responses to the non aromatizable androgens, mesterolone and fluoxymestrone, in 27 patients with primary testicular failure. all patients were given a bolus of lhrh (100 micrograms) and trh (200 micrograms) at zero time. nine subjects received a further bolus of trh at 30 mins. the latter were then given mesterolone 150 mg daily for 6 weeks. the remaining subjects received fluoxymesterone 5 mg daily for 4 weeks and 10 mg daily for 2 weeks. on the la ...19846437958
circulating thyroid hormones in progressive renal failure in the baboon (papio ursinus).in order to examine the effects of developing renal failure on circulating thyroid hormones, serum concentrations of thyroxine (t4), free t4 (ft4), triiodothyronine (t3) and reverse t3 (rt3) and tbg capacity were measured in 9 baboons before and during the progress of acute (mean survival 12 days), subacute (32 days) and chronic (120 days) renal failure following allogeneic renal transplantation. irrespective of the rate of development of renal failure, there were significant, non linear (power ...19846438218
congenital goitrous hypothyroidism: discordant systolic time intervals, pituitary and peripheral responses to high daily doses of t4 or t3 therapy.left ventricular performance was studied by a noninvasive technique through the measurement of the systolic time intervals (total eletromechanical systole, left ventricular ejection (lvet) time, preejection period (pep) and pep/lvet ratio (systolic quotient) in 8 young adults with congenital goitrous hypothyroidism. all subjects showed lengthening of pep, shortening of lvet and an increased pep/lvet ratio associated with low serum t3 and t4, an exaggerated tsh response to trh, high levels of ser ...19846438221
[thyroid diagnosis today].for functional diagnostics the ft4 index is calculated from the t4 and t3u values. hyperthyroidism is suggested or borderline values are found; the t3 test is carried out. an index of free iodine hormones (ifih) can be calculated. (formula; see text) hypothyroidism and borderline cases require tsh evaluation or even a trh test. t4 and t3 autoantibodies can cause high or low values in spite of euthyroidism or hypothyroidism. differences in ft4 values are found if the kits used were not made by th ...19846438696
[blood t lymphocyte populations in the hemophiliac].we have studied a group of 31 hemophiliac patients (hemophilia a: 26 patients, hemophilia b: 5 patients); 29 healthy men were used as controls. hemophiliac patients had increased percentages of suppressor t-lymphocytes and depressed t4/t8 ratios. these abnormalities were found to be significantly correlated with the amount of f viii used per year.19846438768
[immunological study of a hemophiliac treated according to the bonn protocol for 2 1/2 years].a major haemophiliac a, 27 years old, has been treated during 30 months, with high dosage of imported factor viii, in order to reduce the titer of a f viii antibody. a good clinical result has been obtained. no sign of immunodeficiency has been observed. normal values were obtained for t4/t8, ratio b2 microglobulin and no antibody was detected against the lav virus isolated from cases of aids.19846438769
[serum thyroxine (t4) levels and thyroxine-binding capacity of patients with corticosteroid-dependent and atopic bronchial asthma].the patients with bronchial asthma, treated a long time with corticosteroid s (the so called cortico-dependent bronchial asthma) are an adequate model for the study on the dependence between the function of the thyroid gland and the effect of glucocorticosteroids. the study was carried out on 12 patients with atopic, 14--with cortico-dependent bronchial asthma and ii--healthy subjects. the function of the thyroid gland was assessed by the serum level od thyroxine and thyroxine-binding capacity, ...19846438915
age-related alterations of pituitary-thyroid function in normal female subjects and in female patients with simple goitre.age-related alterations in pituitary-thyroid function were studied in 173 female patients with simple goitre and in 70 normal female subjects. they were divided into 4 groups according to age: a group, less than 19 years; b group, 20 to 29 years; c group, 30 to 39 years; d group, 40 to 59 years. serum triiodothyronine (t3) concentrations decreased progressively but insignificantly with age in female patients with simple goitre and in normal female subjects, whereas serum thyroxine (t4) concentra ...19846438974
carbamazepine and thyroid function in affectively ill patients. clinical and theoretical implications.thyroid function was examined in 50 affectively ill patients before and four weeks after carbamazepine treatment. carbamazepine significantly and substantially decreased peripheral thyroid hormone levels while increases in thyrotropin levels, although significant, were of much smaller magnitude. furthermore, the decreases in levels of thyroxine (t4) and free t4 were significantly greater in carbamazepine responders than in nonresponders. these findings are discussed in light of current theories ...19846439170
trh response pattern in adolescent schizophrenic males.a marked elevation in human growth hormone (gh) following intravenous infusion of thyrotropin releasing hormone (trh) was seen in three of seven adolescent male schizophrenic patients receiving neuroleptic drugs, and in one of five controls matched for age, sex, and developmental stage, receiving the same drugs. a positive family history for schizophrenia was noted in all three schizophrenic 'responders' but in only one of the remaining patients. the response patterns of thyroid stimulating horm ...19846439274
a prealbumin variant with an increased affinity for t4 and reverse-t3.a euthyroid adult female (lc) was found to have persistently raised concentrations of total t4 (159 nmol/l) and rt3 (500 pmol/l) in her serum in association with a normal t3 (2.1 nmol/l). serum concentrations of all three t4-binding proteins were within normal limits. a variant prealbumin with an increased affinity for t4 was found to be responsible for the raised serum level of t4. unlike normal prealbumin, the variant also bound appreciable amounts of rt3. the affinity constant for t4 binding ...19846439433
thyroregulatory changes associated with smoking in 70-year-old men.in a previous study we have analysed serum free t4 concentrations in a representative population of 70-year-old men. in the present study the effect of previous or present tobacco smoking on free t4, t4, t3, rt3, tsh and thyroid hormone binding proteins was analysed in 181 of the 460 men, excluding those with past or present goitre, those who were obviously ill or had died between 70 and 75 years of age and those who had any disease or medication influencing free t4 concentrations. smokers had h ...19846439438
transient thyrotoxicosis in endemic goitre patients following exposure to a normal iodine intake.twenty-three endemic goitrous subjects (goitre grade: iii and iv) that were living in a chronic iodine-deficient area (iodine intake: less than 40 micrograms i/d) were submitted to clinical and laboratory evaluation within 3-8 weeks of arrival at the metropolitan area of são paulo, where daily iodine intake is estimated to be 150-200 micrograms i/d. eight patients developed a mild thyrotoxic state (t4 = 14.7 +/- 2.3 micrograms/dl, t3 = 279 +/- 55 ng/dl, no tsh response to trh). five additional s ...19846439440
inhibition of tsh-stimulated thyroid hormone release and potentiation of trh-stimulated tsh release by indomethacin in perifusion systems of rat thyroids and pituitaries.using indomethacin (ind), a prostaglandin synthesis inhibitor, in vivo experiments in rats and in vitro experiments with perifusion systems of rat thyroids and pituitaries were conducted. after 35 days of intragastric infusion of ind, serum tsh levels were markedly increased, the thyroid was swollen and, as a consequence, t3 and t4 levels were normal. the t3 release from perifused rat thyroids under continuous stimulation with 10 mu/ml tsh was inhibited significantly (p less than 0.01) by 1.0 x ...19846439574
serum tsh, t4, t3, ft4, ft3, rt3, and tbg in youngsters with non-ketotic insulin-dependent diabetes mellitus.several parameters of thyroid function were studied in 112 non-ketoacidotic youngsters with insulin-dependent diabetes mellitus (iddm). levels of thyroxine (t4), reverse triiodothyronine (rt3), thyroxine-binding globulin (tbg) and t3 were lower than in controls, whereas ft4, and ft3 were normal. t4 levels in iddm patients were positively related to t3, rt3 and tbg, and inversely related to haemoglobin a1 (hba1). however, only 4 patients showed biochemical hypothyroidism (t4 less than 5 microgram ...19846439616
a study of pituitary-thyroid function during exercise in man.exercise induced modulations in circulatory t4, t3 and tsh were monitored in 14 healthy euthyroid male volunteers undergoing exercise on a bicycle ergometer at 750 kpm for 20 minutes. tsh response to 100 micrograms trh was also studied in 4 exercising and 4 resting subjects. serial blood samples were obtained before, during and after the exercise. serum t4 exhibited a significant decrease (p less than 0.05) from 9.6 +/- 0.49 microgram/dl (mean +/- se) to 8.3 +/- 0.47 microgram/dl at 20 min after ...19846439634
improved survival in carcinoma of the nasopharynx.between 1970 and 1980, we treated 107 previously untreated patients with biopsy-proven carcinoma of the nasopharynx by megavoltage external radiation therapy to the primary site, base of the skull, and both sides of the neck. eighty-seven percent of the patients had stage iv disease (american joint committee 1980), 53% had t4 primaries, and 73% had palpable cervical metastases. the histology was anaplastic or poorly differentiated carcinoma in 81%. the observed 5-year survival rate was 35% for t ...19846439690
mixed beam radiation therapy for unresectable squamous cell carcinomas of the head and neck: the results of a randomized rtog study.three hundred and twenty-two patients with inoperable squamous cell carcinomas of the head and neck were entered on a randomized study comparing "mixed beam" radiation therapy with photon radiation therapy. patients with histologically proven tumors of t-stage t2, t3, or t4 and any n-stage originating in the oral cavity, oropharynx, supraglottic larynx, or hypopharynx were eligible. one hundred forty-five patients were randomized to photon treatment and 177 were randomized to mixed beam treatmen ...19846439699
squamous cell carcinoma of the supraglottic larynx treated with radical irradiation: analysis of treatment parameters and results.eighty-one patients were treated with radical radiation therapy, with or without immediate neck dissection(s), for squamous cell carcinoma of the supraglottic larynx from october 1964 through may 1981. there is a 2-year minimum follow-up on all patients; 75/81 (93%) have a minimum 3-year follow-up, and 58/81 (72%) have at least a 5-year follow-up. patients were staged according to the 1983 ajcc staging system. patients were excluded from the local control analysis if they died less than 2 years ...19846439701
iodothyronine 5'-deiodinase in rat kidney microsomes. kinetic behavior at low substrate concentrations.the thiol-activated enzymatic outer-ring monodeiodination of iodothyronines by rat kidney microsomes at low (nanomolar) substrate concentrations shows an apparently sequential reaction mechanism and is further characterized by insensitivity to inhibition by dicoumarol, a moderate sensitivity to inhibition by propylthiouracil (ki = 100 microm) and iopanoic acid (ki = 0.9 mm), responsiveness to 5 mm glutathione (gsh), and a thermal activation profile that is concave downward with a td of approxima ...19846439742
tsh secretion in thalassemia.thyroid function has been evaluated in 6 prepubertal male and 9 female thalassemic patients. four of the latter were sexually immature (group i), with very low estradiol levels and the remainder had more advanced sexual development (group ii). subjects were challenged with trh and the response compared to adult controls and a group of 15 males aged 13-18 years with constitutional delayed adolescence. all patient groups and controls had normal levels of t4, t3 and t3 resin uptake. when compared t ...19846439771
recovery of serum tsh and thyroid hormones after 3'isopropyl-3,5-diiodo-l-thyronine (diip) treatment: absence of inhibiting effect of bromocriptine on tsh secretion and evidence for autoregulation of serum t3 levels.bromocriptine, because of its dopaminergic activity, could possibly inhibit tsh secretion. this hypothesis was tested in 7 normal male volunteers. thyroid function was suppressed with the very potent thyromimetic analogue, 3'isopropyl-3,5-diiodo-l-thyronine (diip). we wanted to observe, after stopping this treatment, whether the return of serum t3, t4, rt3 and tsh values was influenced by concomitant bromocriptine treatment (5 mg/day). for comparison, the diip study was also performed without br ...19846439772
interaction of a streptococcal cell wall tetraheteroglycan and salmonella telaviv lipopolysaccharide with polymeric mcpc 870 and mopc 384 mouse iga myeloma proteins.interactions of polymeric mcpc 870 and mopc 384 mouse iga myeloma proteins with a streptococcal cell wall tetraheteroglycan (t4-antigen), salmonella tranoroa lipopolysaccharide (lps), s. telaviv lps and its lipid a free polysaccharide were examined by the quantitative precipitin method. hapten inhibition of myeloma protein precipitation by t4-antigen or s. telaviv lps indicates a complex anticarbohydrate specificity for 870 and 384 protein combining sites involving several sugars. while the comb ...19846440009
possible altered dopaminergic modulation of pituitary function in normal-menstruating women with insulin dependent diabetes mellitus (iddm).in order to assess whether a possible altered dopamine activity in normal-menstruating diabetic patients may influence the pituitary hormone secretion we have measured the basal serum concentrations of prl, lh and fsh in 28 patients with insulin dependent diabetes mellitus (iddm) and in 55 normal-menstruating women at day 3 to 6 of the menstrual cycle. in addition basal levels of oestradiol-17 beta, tsh, thyroxine (t4), triiodothyronine (t3) and resin-t3 uptake (rt3u) were determined in 17 patie ...19846440390
resistance of peripheral tissues and pituitary to thyroid hormone.we describe a 29-year-old male with thyroid hormone resistance. he was first seen because of a goiter, and was considered to have hyperthyroid graves' disease. despite subtotal thyroidectomy followed by radioiodine therapy, serum thyroxine levels were elevated with high serum tsh levels. baseline thyroid function showed serum thyroxine of 16.6 micrograms/dl, free thyroxine of 4.60 ng/dl, triiodothyronine of 197 ng/dl, and tsh of 34 microu/ml. triiodothyronine administration by gradually increase ...19846440779
the thyroid reserve in children with chronic lymphocytic thyroiditis revealed by the thyrotropin-releasing hormone and thyroid-stimulating hormone tests.serum thyroid hormone and tsh concentrations were measured before and after the administration of trh (10 micrograms/kg body weight) and bovine tsh (10 iu) in 14 children with chronic lymphocytic thyroiditis. the trh test showed that the responsiveness of tsh was positively correlated with the basal tsh (p less than 0.001) and inversely with the increase in serum thyroid hormones, for delta t3 (p less than 0.05) and for delta t4 (p less than 0.001). overall, the patients had significantly lower ...19846440780
synthesis and expression of rnase t1 gene.in order to obtain knowledges about structure-function relationship of ribonuclease t1, we synthesized a structural gene for rnase t1 and several its modified genes. using amino acid codons frequently used in escherichia coli we designed genes consist of 328 x 2 bases. synthesis of oligodeoxynucleotides with 9-20 base lengths was performed by 1% polystyrene supported triester approach and resulting 42 oligomers were joined together using t4 dna ligase. the product was analyzed and utilyzed to co ...19846441155
in vitro inhibition of growth of neisseria gonorrhoeae by neisseria meningitidis isolated from the pharynx of homosexual men.despite the high prevalence of pharyngeal gonorrhea and of meningococcal carriage among homosexual men, neisseria gonorrhoeae and neisseria meningitidis are rarely co-isolated from the throat. forty-seven meningococcal isolates from the pharynx of homosexual men were examined, by a lawn-spotting method, for their ability to inhibit n. gonorrhoeae in vitro. eight (17%) of the meningococcal isolates were inhibitory when tested against gonococci from the same patient, while 31 (66%) were inhibitory ...19846441274
prognostic significance of clinical nodal involvement in patients treated by radical radiotherapy for a locally advanced breast cancer.a group of 230 female patients, treated between 1960-1976 with radical megavoltage radiotherapy for locally advanced breast cancer (t3 greater than 7 cm-t4 stage), was analyzed retrospectively. those with inflammatory cancer or evidence of disseminated metastatic disease were excluded. clinical axillary nodal involvement appears to be a very important prognostic feature. actuarial disease-free survival at 5 years for the 109 patients with clinically negative nodes (n0n1a) is 52%; whereas it is 2 ...19846442097
radiation treatment of lateral epilaryngeal cancer. prognostic factors and results.treatment results of epilaryngeal cancer are rarely individualized in the world literature. for this purpose, we have reviewed the records of 167 patients with squamous cell carcinoma of the lateral epilarynx who received radical radiotherapy at the institut curie on a megavoltage unit, between 1959-1975. two-thirds of the lesions were located at the junction of the ary- and pharyngo-epiglottic folds and lateral border of the epiglottis. forty-four percent of patients had advanced primary lesion ...19846442098
treatment of squamous carcinoma of the retromolar trigone.since squamous carcinoma of the retromolar trigone is unusual, there is a paucity of information in the world's literature to use as a reference for selecting treatment and determining pertinent factors affecting prognosis. consequently, an analysis of the medical records of 110 patients with biopsy proven squamous carcinoma originating in the retromolar trigone, seen and treated entirely at the university of texas m.d. anderson hospital and tumor institute at houston from 1965-1977, with at lea ...19846442099
