| pituitary-thyroid function in spironolactone treated hypertensive women. | four weeks high dose spironolactone treatment (aldactone searle, 100 mg q. i. d.) significantly enhanced the tsh (delta max. 8.5 +/- 4.1 vs. 4.6 +/- 3.1 microunits/ml, p less than 0.05) and t3 (delta max. 32 +/- 27 vs. 11 +/- 16 ng/100 ml, p less than 0.05) responses to an intravenous trh/lh-rh bolus injection in 6 eumenorrhoeic euthyroid hypertensive women, without affecting basal serum tsh, t3 or t4 levels or the basal and stimulated lh, fsh and prolactin values (p greater than 0.10). the mean ... | 1979 | 107696 |
| adverse hemodynamic and ultrastructural changes in dog hearts subjected to protein-calorie malnutrition. | in the absence of thiamine deficiency, the specific effects of protein-calorie malnutrition on left ventricular (l.v.) function are unknown. mature beagle dogs of both sexes were subjected to a hypocaloric, nitrogen-poor diet which resulted in a weight loss of approximately 40% after seven weeks. following preparation of this nutritional model, myocardial contractility was assessed acutely by obtaining isovolumetric l.v. contractions on cardiopulmonary bypass at constant heart rate, mean aortic ... | 1979 | 107775 |
| pseudomonas orbital cellulitis. | a 3-month-old infant being treated for bronchitis developed a rapid onset but otherwise typical orbital cellulitis. because gram-negative infections and septicemia are common occurrences in the newborn nursery, this patient was given systemic gentamicin and ampicillin. sinus x-rays were not attempted. two days after treatment the eyelids were opened. a strikingly large corneal ulcer with perforated globe and endophthalmitis was found. pseudomonas aeroginosa was cultured from the blood, conjuncti ... | 1979 | 107805 |
| experimental transmission of wuchereria bancrofti to monkeys. | infective larvae of wuchereria bancrofti from laboratory-raised culex pipiens fatigans and aedes togoi mosquitoes fed on human volunteers in jakarta, indonesia (j strain) and kinmen island, china (k strain) were introduced into taiwan monkeys (macaca cyclopis) by subcutaneous inoculation, by foot puncture, or by permitting infected mosquitoes to feed weekly on the monkeys. some animals were splenectomized and others were treated with varying regimens of immunosuppressants. necropsy was done on m ... | 1979 | 107818 |

| influence of alvogyl on the healing of extraction wound in man. | eight volunteer patients free of any systamic disease underwent extraction of two teeth on the same day. one extraction socket was packed with alvogyl, the other served as a control wound. biopsies for histological assessment were taken from both sockets 1 and 2 weeks after extraction. histological study revealed the normal sequence of wound healing in the sockets allowed to heal spontaneously. on the other hand, the signs of retarded wound healing (acute inflammatory infiltrate, persistent gran ... | 1979 | 107131 |
| rubella virus maturation and production in two host cell systems. | when inoculated at the same moi, vero cells released a larger amount of infectious rubella virus into the culture medium than did bhk21 cells, however, bhk21 cells (in monolayer or in suspension) produced more intracellular infectious virus than vero cells when tested 24 h after infection. maturation of the virus in bhk21 cells occurred at the plasma membrane and, in a larger quantity, in the cytoplasm (golgi apparatus and vacuoles). viral particles consisted of an electron-dense core (32 nm) su ... | 1979 | 107143 |
| overall pathway of mononucleosome production. | five electrophoretically distinguishable classes of mononucleosomes (mi, mii, ...mv) are produced upon treatment of mammalian nuclear chromatin with micrococcal nuclease. these five forms differ in their initial dna lengths, relative mass proportions, stability, contents of histone h1, and presence of certain nonhistone proteins. a new "chromatin fingerprinting" technique has been developed in order to trace nuclease-mediated interconversions between these mononucleosomes and their polynucleosom ... | 1979 | 107168 |
| acetylated methylmannose polysaccharide of streptomyces griseus. locations of the acetyl groups. | the positions of esterification of the 4 to 5 acetyl residues in the acetylated methylmannose-containing polysaccharide from streptomyces griseus have been established by the methyl replacement technique, wherein ester substituents are specifically replaced with methyl ether substituents. the newly incorporated methyl groups were distinguished from 3-o-methyl groups by the use of polysaccharide containing radioactively labeled endogenous methyl groups. the positions of methyl group localization ... | 1979 | 107171 |

| percutaneous nitroglycerin absorption in rats. | percutaneous nitroglycerin absorption was studied in shaved rats by monitoring unchanged plasma drug concentrations for up to 4 hr. drug absorption from the neat liquid state or from an alcoholic solution was considerably poorer than that from a commercial ointment. this observation was unanticipated since the driving force for percutaneous drug absorption was assumed to be drug thermodynamics. potential artifacts such as drug volatilization from the skin, reduction of surface area through dropl ... | 1979 | 107313 |
| the antinociceptive effect of intracerebroventricularly administered prostaglandin e1 in the rat. | it is generally accepted that prostaglandins (pgs) are nociceptive substances. however, earlier studies from this laboratory indicated that morphine analgesia, in the rat, was not only serotonin mediated, but involved pgs as well. several pg synthesis inhibitors were shown to inhibit morphine analgesia and pge1 was shown to potentiate the antinociceptive effect of morphine. intraperitoneal administration of pge1, but not pge2 and pgf2alpha, elicited antinociceptive effect per se, by the radiant ... | 1979 | 106425 |
| effects of atenolol and propranolol on human performance and subjective feelings. | in a double-blind, double crossover experiment, 18 healthy young men received over 3-day periods either 100 mg atenolol, 80 mg propranolol, or placebo. the subjects underwent various motor and cognitive tests 18 h after each last dose had been taken. propranolol significantly increased variability of a choice reaction-time task. scores on various subjective rating scales showed that propranolol had a larger mood elevating effect than atenolol. heart rate and blood pressure were significantly red ... | 1979 | 106432 |
| [isolation and general characteristics of a group of pseudomonas aeruginosa temperate phages]. | eighteen temperate phages were isolated from 38 natural strains of pseudomonas aeruginosa. the phages belong to five heteroimmune groups according to the ability of lysogenic variants of the strains pao1 and pat2 to exclude the growth of the superinfecting phage. phages of the ii and v immunity groups are serologically similar; the remaining phages are not inactivated by antisera against phages b26 (ii group) and k1338 (v group). prophages of the ii, iv, and v groups are induced by uv for vegeta ... | 1979 | 106221 |

| turnover of human and monkey plasma kininogens in rhesus monkeys. | the normal metabolic turnover of plasma kininogens was studied by measuring the disappearance of intravenously administered radiolabeled human and monkey plasma kininogens from the circulation of healthy adult rhesus monkeys. curves obtained by plotting log radioactivity against time could be expressed as double exponential equations, with the first term representing diffusion, and the second, catabolism. no significant difference between the turnovers of human and monkey kininogens was observed ... | 1979 | 105015 |
| implications for adult roles from differential styles of mother-infant bonding: an ethological study. | ethological observations of maternal and infant behaviors of nine vervet monkey pairs (cercopithecus aethiops sabaeus) showed the effects of differential styles of early maternal responsiveness on later infant competence. those infants receiving the least amount of maternal responsiveness and the most time-off the mother in the first 3 months of development were more socially competent at 6 months of age. the results are discussed within current ethological "attachment" theories. the detachment ... | 1979 | 105083 |
| the pathophysiology of asthma. | because postmortem studies of humans provide little information on the initial pathophysiologic events in asthma, animal models have been developed. recently the ascaris-allergic rhesus monkey has provided an opportunity to examine the onset of pathophysiologic changes following challenge and to correlate them with airway structure. these studies have suggested that the initial interaction between antigen and mast cells may occur in the bronchial lumen or in the epithelium superficial to the tig ... | 1979 | 89006 |
| trasylol prevents trypsin-induced shock in dogs. | the effect of simultaneous intravenous administration in the dog of bovine trypsin and trasylol followed by continued infusion of trasylol was studied. special attention was paid to the interchange between the dominating plasma protease inhibitors alpha1-antitrypsin and a-macroglobulins and to the disappearance of trasylol and its trypsin complexes from the circulation. the following results were obtained: 1) trypsin was preferentially bound by the alpha-macroglobulins, though trasylol is a stro ... | 1979 | 89067 |

| latex fetuin spheres as probes for influenza virus neuraminidase in productively and abortively infected cells. | fetuin bound latex spheres do not adhere to the membranes of non-infected cells but adhere to those of cells productively infected by fowl plague virus (fpv dobson strain). in contrast, asialo fetuin spheres do not attach to the membranes of productively infected cells. moreover latex fetuin spheres incubated with extracts of productively infected cells and extensively washed are specifically enriched in neuraminidase activity without any trace of haemagglutinin. these observations suggest that ... | 1979 | 91354 |
| ultrastructure of peripheral nerves of mice inoculated with rabies virus. | fourty adult female albino mice were inoculated in the right hind leg with rabies viruses of the street type. the mice were sacrificed with an interval of 24 hours each, starting in the next day after inoculation. from the 10th day ownwards the animals started presenting signs of paralysis, first on the leg where the viruses were inoculated anbnormalities were found in peripheral nerves compatible with axonal degeneration with secondary demyelination but the rabies viruses were not found in the ... | 1979 | 91359 |
| [anti-arrhythmic effect of tetrodotoxin in the late stage of experimental myocardial infarct]. | the action of tetrodotoxin (tt), blocking the fast sodium current, on arrhythmias that occurred 24 hours after occlusion of the coronary artery was studied in 10 dogs. tt injected intravenously in doses of 0.5--3.0 micrograms/kg significantly decreased the number of ventricular extrasystoles, and completely restored sinum rhythm in 4 animals. the maximum antiarrhythmic effect was noted 3 to 5 minutes after tt adminstration. it is suggested that arrhythmias and the antiarrhythmic effect of the dr ... | 1979 | 91393 |
| connectivity of the auditory forebrain nuclei in the guinea fowl (numida meleagris). | injection of tritiated leucine and proline into the nucleus ovoidalis of the guinea fowl (numida meleagris) produces terminal labeling in the palaeostriatum and in three adjacent zones (field l1-l3) of the auditory neostriatum (an). l2, situated between l1 and l3, receives the main input and corresponds to the former field l of rose. these neuroanatomically defined zones of the auditory neostriatum are also characterized by differing properties of their neurons. injection of radioactive material ... | 1979 | 91442 |
