| the cathode bound group antigen of dysentery-provoking escherichieae (author's transl). | antigens from disrupted cells of dysentery-provoking and of non-enteropathogenic escherichieae were submitted to immunoelectrophoresis on cellulose acetate stripes at ph 8.0. among 6 immune sera produced for this purpose by immunizing rabbits against desintegrated dysentery bacteria, only one contained a precipitine reacting with an antigen similar to the "generic antigen" of belaya. this - at ph 8.0 - cathode-bound group antigen (kga) could not only be found in virulent but also in 5 attenuated ... | 1975 | 873 |
| use of lincomycin, methicillin and ristomycin in the nutrient media for isolating pathogenic intestinal microorganisms. | elective-differentiating solid nutrient media for simultaneous isolation of vibrioes, salmonella and shigella were developed. antibiotics active against grampostive microflora and dry bile salts inhibiting the growth of proteus were used as the inhibitors of the growth of the accompanying microflora. the medium was lincomycin and the bile salts may be prepared in a dry form. | 1975 | 2096 |
| lactulose therapy in shigella carrier state and acute dysentery. | antibiotic-resistant shigella are increasingly prevalent. lactulose, a non-absorbable disaccharide, was investigated as an alternative therapy for shigella infection on the hypothesis that the short-chain fatty acids (inhibitory to shigella) resulting from metabolism of lactulose by normal colonic flora would diminish shigella excretion. a long-term antibiotic-refractory carrier (large bowel) excreting 10(4) to 10(7)shigella sonnei/g of feces was given two courses of lactulose (of 24 and 16 days ... | 1975 | 2098 |
| testicular androgen binding protein (abp) - a parameter of sertoli cell secretory function. | using abp as an index of sertoli cell secretory function, several important features of the sertoli cell have emerged: 1. the stimulation of abp production by fsh clearly points to the sertoli cell as a target cell for fsh (3,4,9-16,21,24). 2. the dramatic effects of androgens on abp production both in immature and mature rats also suggest that the sertoli cell is a target cell for androgen (3,12,14,16,25). 3. the striking reduction in abp production in the cryptorchid testis raises the question ... | 1975 | 18322 |

| intramyocardial pressure: effect of preload on transmural distribution of systolic coronary blood flow. | impairment of systolic coronary blood flow (cbf) may be mediated by intramyocardial pressure (pim). however, the effect of systole on the magnitude and transmural distribution of coronary blood flow has not been investigated. the purpose of this study was to measure this effect, and, indirectly, intramyocardial pressure. it is assumed that intramyocardial pressure acts on the coronary vessels as a starling resistor, such that local coronary blood flow is determined by the equation: coronary perf ... | 1975 | 124128 |
| hepatic mitochondrial function in ketogenic states. diabetes, starvation, and after growth hormone administration. | the study was designed to evaluate hepatic mitochondrial function during ketotic states. the ketogenic models studied were streptozotocin-induced diabetic ketoacidosis, 48 h of starvation, and after growth hormone administration. in the last-mentioned model we observed increased free fatty acids but not ketonemia. oxidative phosphorylation was measured using the citric acid cycle substrates pyruvate and succinate, the amino acid glutamate, a ketone body beta-hydroxybutyrate, and a long-chain fat ... | 1975 | 124319 |

(diptera, oestridae)]. | on the basis of observations undertaken in azerbaijan and available literary data the author considers the hypotheses concerning the reasons causing the delay of the ist instar larvae development and determining the age structure changes in population of oestrus ovis l. within a year. the main reasons are as follows: factors depending on the population density at the larval phase, the light day duration within the life cycle of the botfly females. | 1975 | 124845 |
| stimulation of syngeneic and allogeneic lymphoid cells by tumour cells in vitro. | august and wistar rat lymph node cells were found to respond well to pha stimulation and in mixed lymphocyte culture, as determined by an increased incorporation of 3h-thymidine. august rat lymph node cells were also stimulated by incubation with irradiated syngeneic tumour cells. allogeneic wistar rat lymph node cells produced a larger response to the august tumour cells. the response of syngeneic and allogeneic lymph node cells was reduced by pretreating the tumour cells with a wistar anti-tum ... | 1975 | 126072 |
| cytochemical identification of atpase-positive langerhans cells in edta-separated sheets of mouse epidermis. | sheets of epidermis for incubation to demonstrate atpase activity were obtained from specimens of mouse footpad using edta as the separation medium. the use of edta in place of the nabr method previously described, resulted in a greatly reduced incubation time, precise localization of reaction product and preservation of ultrastructural detail. a population of closely and regularly spaced atpase-positive dendritic cells was demonstrated by light microscopy. electron microscopy demonstrated that, ... | 1975 | 126073 |

| interactions of the third component of complement (c3) with cross-linked dextran. iii. isolation and characterization of interacting components after enzymatic digestion of complement coated cross-linked dextran. | in previous investigations we could show that incubation of cross-linked dextran (sephadex) with normal human and normal guinea pig serum results in the binding of c3 to sephadex. this binding was found to be due to activation of c3 via an alternate pathway. in this paper data are presented which show that components bound to sephadex can be recovered after enzymatic digestion of serum-reacted sephadex beads. the digests were characterized with immuno-electrophoresis and double immunodiffusion t ... | 1975 | 126570 |
| effect of methysergide, a blocker of serotonin receptors, on plasma prolactin levels in lactating and ovariectomized rats. | the effect of methysergide (mes, 2.5 mg/100 g body wt), a serotonin antagonist, on prolactin release has been studied in lactating and ovariectomized rats. mes caused significant increases in prolactin release in both animals. studies in ovariectomized, hypophysectomized rats indicate that this effect is not due to a decrease in the peripheral metabolism of prolactin. in vitro incubations of anterior pituitary fragments with mes failed to demonstrate any increase in prolactin release, suggesting ... | 1975 | 126860 |
| characterization of 5.8s ribosomal ribonucleic acid in neurospora crassa. | neurospora crassa ribosomes contain a species of ribonucleic acid (rna) of molecular weight 54,000, similar to 5.8s ribosomal rna previously described for other eukaryotic organisms. the 5.8s rna from n. crassa was found to be released by heat treatment at 60 c from 25s ribosomal rna but not from 18s ribosomal rna. the base composition of n. crassa 5.8s rna was similar to that of 5.8s rna from saccharomyces cerevisiae, but differed from animal 5.8s rna. during the course of this study, it was di ... | 1975 | 126993 |
| purification and properties of membrane-bound coupling factor-latent atpase from mycobacterium phlei. | the membrane bound coupling factor-latent atpase was solubilized from the membrane vesicles of mycobacterium phlei by using 0.25 m sucrose or low ionic strength buffer. purification of the solubilized enzyme by use of sepharose-adp conjugate gel yielded a homogenous preparation of latent atpase which was purified about 216-fold in a single step with an 84% yield. the enzyme exhibits a specific activity of 39 mumoles of atp hydrolyzed per min per mg protein. the purified enzyme exhibits coupling ... | 1975 | 127086 |
| the significance of coronary arterial stenosis during cardiopulmonary bypass. | myocardial infarction may develop during an uneventful open-heart operation. in order to better understand this complication, we undertook an experimental study. the left circumflex coronary artery of 20 dogs was narrowed to 50 per cent of its area by a metal screw clamp to produce a localized coronary stenosis. regional myocardial perfusion in the distribution of both the stenotic circumflex and normal left anterior descending (lad) coronary arteries was measured by injection of a radioactive-l ... | 1975 | 127092 |
| the hurler syndrome: treatment of cultured hurler fibroblasts with normal human serum. | prolonged replacement of fetal calf serum by normal human serum for the enrichment of medium during tissue culture of hurler fibroblasts resulted in increased acid mucopolysaccharides in the cells and in the medium. the predominant intracellular mucopolysaccharide had the characteristics of dermatan sulfate when hurler cells were treated with either serum. normal human serum contains a nonspecific coreective factor capable of augmenting the loss of 35so4-amps from hurler cells, but not from norm ... | 1975 | 127180 |

| human muscle spindles: fine structure of the primary sensory ending. | the primary sensory innervation of muscle spindles obtained by muscle biopsy of normal human volunteers was studied with the light and electron microscopes. the parent ia sensory fibre branched 4-6 times, became unmyelinated for 25-30 mum, then formed sensory terminals on each nuclear bag and chain intrafusal muscle fibre. the first 4--5 mum of the unmyelinated segment is believed to be an encoder zone because the plasmalemma was undercoated by a dense granular layer similar to that under other ... | 1975 | 127831 |
| observations on epizootiology and distribution of elaeophora schneideri in montana ruminants. | seventy-four moose, 111 elk, 20 mule deer, 8 white-tailed deer, 26 prong-horn antelope, 42 domestic sheep and 3 bighorn sheep from montana or northwestern wyoming were examined post-mortem for evidence of elaeophora schneideri infection in 1973-74. fifteen percent of the mule deer and four percent of the moose were positive for adult arterial worms. this constitutes the first report of e. schneideri in mule deer in montana. no gross signs of blindness or other neurologic disorder were evident in ... | 1975 | 127848 |
| microautoradiographic study of cell proliferation in compensatory renal growth. | dna synthesis in the renal parenchyma was studied by electron microscopic autoradiography 48 and 72 hours after unilateral nephrectomy in mice and weanling rats. the proportion of labelled nuclei belonging to the epithelium, endothelium, interstitial areas, or circulating cells was evaluated. most of cells showing dna synthesis were epithelial but many belonged to stroma. all the nephron segments were found to participate in compensatory hyperplasia, with a greater contribution, however, of the ... | 1975 | 127941 |

| physiopathological aspect of glynn's type of experimental arthritis. | knee joint arthritis is induced among rabbits previously immunized by intradermal injection with egg albumin (ea) emulsified in adjuvant containing either m. tuberculosis or m. butyricum, then by intra-articular injection with ea. arthritis evolution involves two phases, an early one during the first 2 months and a late one from 3 months to 1 year. during the early phase, arthritis intensities are similar no matter which mycobacterium is used. however, during the late phase, only rabbits immuniz ... | 1975 | 128112 |
| [solubility of the mg2+-dependant ca2+-activated atpase fraction of the plasma membranes of synaptosomes]. | mg2+-dependent ca2+-activated atpase (mg2+,ca2+-atpase, ec 3.61.4) in the fraction of synaptosome plasmatic membranes is activated with 0.05-0.08% solutions of digitonin and sodium deoxycholate. at higher concentrations of digitonin the activating effect lowers, sodium deoxycholate in the increasing concentrations inactivates the enzyme. 0.08% digitonin activates mg2+,ca2+-atpase of synaptosome membranes, without demanding for its transition into solubilized state. separation of non-active 0.08% ... | 1975 | 128171 |
| [enzymatic properties in muscle membranes]. | a study in the enzymatic properties of muscle membranes established that sarcolemma of the rabbit skeletal muscles contains the ca2+-atpase system which does not require mg2+ for manifestation of ions activity. by some kinetic properties it differs from atpase of myosin. the complex ca-atp2+ is a substrate of ca2+-atpase. ions of a series of bivalent metals inhibit the latter as well as the passive transport of ca2+, that may evidence for a definite relation of ca2+-atpase with ca+2 transport in ... | 1975 | 128174 |

| prevention of gram-negative bacillary pneumonia using polymyxin aerosol as prophylaxis. ii. effect on the incidence of pneumonia in seriously ill patients. | all 744 patients admitted to a respiratory-surgical intensive care unit (rsicu) were included in a prospective study of the effects of a polymyxin (2.5 mg/kg body wt/day in six divided doses) or a placebo aerosol sprayed into the posterior pharynx and tracheal tube (if present), during 11 alternating 2-mo treatment cycles. the incidence of upper airway colonization in the rsicu with pseudomonas aeruginosa was 1.6% during the polymyxin treatment cycles (total 374 patients) and 9.7% during the pla ... | 1975 | 163848 |
| pathophysiology of acupuncture: nervous system transmission. | as far as we know, this is the first scientific report which shows distinctly that acupuncture is transmitted directly by the nervous system and the performance of analgesic acupuncture requires an intact nervous system. the more distal the acupuncture treatment is given upon the nerve, the greater the degree of analgesia is afforded. the slowing from a normal awake beta to a normal awake alpha electroencephalographic rhythm may have some effect on the patient's pain perception but further inves ... | 1975 | 164810 |
| oncogenic transformation of murine lymphoid cells by in vitro infection with abelson leukemia virus. | spleen cell cultures stimulated to dna synthesis by antigen or mitogen were infected with abelson virus, a c-type rna virus inducing nonthymic lymphomas in mice. after 3 days the cells were transferred to mice and caused 100 percent incidence of lymphomas in as few as 29 days. that a number of the tumors were of donor origin, as shown by female karyotypes in recipient male mice, indicated that cells infected by virus in vitro were transformed. the process depended upon both virus and stimulation ... | 1975 | 165315 |

| thymosin-induced differentiation of murine thymocytes in allogeneic mixed lymphocyte cultures. | calf thymosin is shown to enhance the one-way mlr of cba thymocytes cultured with allogeneic mitomycin-c- treated c57bl/j6 spleen cells. thymosin does not enhance the one-way mlr of cba thymocytes cultured with syngeneic mitomucin-c-treated spleen cells. based on this finding we present a relatively simple, rapid and quantitative in vitro microculture hioassay for inducers of t-cell differentiation and propose that thymosin treatment, when accompanied by antigen presentation, induces the two-ste ... | 1975 | 165764 |
