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

[effects of the electric current on the fundamental processes of stimulation in the heart].	on the basis of experimental studies on isolated preparations from different regions of the heart and on perfused hearts of animals, it was possible to distinguish at least four basic actions of an electric current: 1. the release of excitations, 2. with continuous current, an electro-tonic influence on the pacemaker activity in the sense of a cathodic advancement, or an anodic inhibition 3. with alternating current, stimulation of the vegetative nerves of the heart, 4. a direct, reversible dama ...	1975	58696
cell-mediated immune response in mice treated with steroidal contraceptives.	the splenomegaly assay (simonsen, 1962) was standardized using different strains of rats and mice. male wistar rat (donor)-female swiss mouse (host) was found to be the suitable combination that could be employed in subsequent experiments to study the potential of contraceptive steroids to alter cmir. the index of splenomegaly appeared to increase in case of mice treated with combination oral contraceptives (ovulen, ovral or enovid). the differences observed, however, neared significance only in ...	1975	55327

evidence that the deferential vein acts as a local transport system for androgen in the rat and the dog.	ligation of the deferential vein of the rat has been shown to bring about a reduction in the androgen-dependent activity of the prostatic rna polymerase enzyme. in the dog, the content of androgens in this vein is of the order of that found in the testicular vein and many times higher than that of peripheral plasma. it seems that the cauda epididymidis alone is sufficient to maintain the ipsilateral lobes of the prostate and seminal vesicles providing an intact ductus deferens and contralateral ...	1975	123961

in vitro effect of methylprednisolone on protein synthesis of activated canine thymus-derived lymphocytes.	technics of studying the protein synthesis of canine thymus-derived lymphocytes in vitro have been developed. activation of these cells by pha or mlc increases protein synthesis. methylprednisolone decreases the stimulation of protein synthesis of these activated lymphocytes. the decrease in protein synthesis is not caused by lympholysis. in this respect, the dog, like man, can be considered a steroid-resistant animal. it is postulated that this effect of methylprednisolone contributes to its im ...	1975	128165
binding of antibodies onto the thylakoid membrane. i. maximal antibody binding and adsorption of antibodies to lipids.	the binding of antibodies onto the lamellar system of antirrhinum majus was determined in dependence on the serum addition. the unspecific adsorption of serum proteins was taken into account or eliminated. the binding of antibodies as a function of the amount of serum added is seem from a saturation curve. from an antiserum obtained by hyperimmunization with stroma-freed chloroplasts, the chloroplasts bind maximally 1 gram antibodies per gram stroma-freed chloroplasts. from an antiserum to the p ...	1975	126591

hypogammaglobulinemia predisposing to infection in foals.	measurement of serum immunoglobulins in 46 foals less than 2 weeks old revealed 9 foals with hypogammaglobulinemia. the hypogammaglobulinemia was attributed to failure in transfer of immunoglobulins from dam to foal via colostrum. three of the affected foals did not nurse at all, or only slightly, and 2 of these died of infections within a few days after birth, whereas the 3rd foal did not grow as well as normal foals. six of the affected foals nursed in an apparently normal manner, and 5 of the ...	1975	162901
the biogenesis of mitochondrial membranes in the yeast saccharomyces cerevisiae.	membrane lipids of yeast mitochondria have been enriched by growing yeast cells in minimal medium supplemented with specific unsaturated fatty acids as the sole lipid supplement. using the activity of marker enzymes for the outer (kynurenine hydroxylase) and inner (cytochrome c oxidase and oligomycin-sensitive atpase) mitochondrial membranes, arrhenius plots have been constructed using both promitochondria and mitochondria obtained from o2-adapting cells in the presence of a second unsaturated f ...	1975	164216

functional consequences of modifying highly reactive arginyl residues of fructose 1,6-bisphosphatase. loss of monovalent cation activation.	modification of pig kidney fructose 1,6-bisphosphatase with 2,3-butanedione (in the presence of amp) results in the loss of activation of the enzyme by monovalent cations. under these conditions about 8 arginyl residues per mole of enzyme were modified. no other residues were modified. no loss of monovalent cation activation occurs when modification with 2,3-butanedione is carried out in the presence of amp plus the substrate fructose 1,6-bisphosphate and 3.2 less arginyl residues were modified. ...	1975	169892
tumor-inhibiting properties of the neutral p-o-ethyl ester of adenosine 3':5'-monophosphate in correlation with its crystal and molecular structure.	the p-o-ethyl ester of camp has been synthesized, its inhibition of solid and ascites tumors studied, and its pattern of urinary excretion followed. et-camp is more effective than camp against solid sarcoma 180 in mice and against ehrlich ascites carcinoma cells in tissue culture. the urinary excretion pattern of injected e-t-camp suggests that about two-thirds of the injected dose (13 mumol per animal) is retained in the rat rather than being promptly excreted. liver slice studies of the effect ...	1975	165504
importance of the so-called 'other' sexually-transmitted diseases.	(1) some data are presented concerning the frequency and potential morbidity of sexually-transmitted organisms other than t. pallidum or n. gonorrhoeae. (2) most of the diseases with which these organisms are associated are more prevalent than syphilis and some, at least in one sex, are as common as gonorrhoea. a number appear to carry considerable morbidity, which in the case of type ii herpes virus--if it is responsible for cervical cancer--may ultimately cause more fatalities than syphilis.

a spin-label study on fusion of red blood cells induced by hemagglutinating virus of japan.	fusion of red blood cells (rbc) induced by hemagglutinating virus of japan (hvj) has been studied using a phosphatidylcholine spin label. the spin label was readily incorporated and diffused into the lipid bilayer portion of the viral envelope. the exchange broadening in the electron spin resonance (esr) spectrum of densely labeled virus disappeared rapidly when the virus was mixed with rbc at 37 degrees. the spectrum gradually approached that of the host cell spin labeled with the phosphatidylc ...	1975	169884

effect of acute inhibition of adrenocorticotrophin secretion on plasma corticosteroids in the rhesus monkey (macaca mulatta).	the half-life of plasma cortisol in the rhesus monkey (m. mulatta), determined by two methods, was about 130 min and longer than that in man; it was unaffected by administration of dexamethasone. dexamethasone (5 mg, i.v.) immediately inhibited the secretion of acth from the monkey pituitary. the plasma half-life of nh2-terminal immunoreactive acth was found to be about 55 min which was much longer than the biological half-life. the adrenal synthesis of cortisol was inhibited by metyrapone which ...	1975	173773
