| comparison of argininosuccinate synthetase from young and old rat livers. | properties of argininosuccinate synthetases (ass), including immunological properties and heat stability, from young and old rats were quite similar. however the degradation rates of ass from young and old rats were found to be different as shown in the experiment using the double labeling technique. three forms of this enzyme from young and old rat livers were separated by deae-sephadex a-50 column chromatography, and they were called ass 1, 2 and 3 in order of elution. the degradation rate of ... | 1981 | 6798716 |
| biological functions and receptor binding activities of equine chorionic gonadotrophins. | the role of equine chorionic gonadotrophin (cg, formerly termed pregnant mare serum gonadotrophin, pmsg) in maintaining equine pregnancy was investigated by examining the effects of this hormone on the maternal ovaries during early gestation and relating these findings to the receptor binding activities of cg in vitro. measurement of plasma progestagen profiles in mares and donkeys carrying horse, donkey, mule ( female horse x male donkey) and hinny (female donkey x male horse) conceptuses confi ... | 1981 | 6265633 |
| sickled erythrocytes accelerate clotting in vitro: an effect of abnormal membrane lipid asymmetry. | a membrane lipid abnormality induced by sickling and found as a permanent alteration in the irreversibly sickled cell (isc) is the rearrangement of phosphatidyl ethanolamine (pe) and phosphatidyl serine (ps) from the inner to the exterior side of the lipid bilayer. since ps can provide a catalytic surface for the binding of blood coagulation factors and thus can exhibit procoagulant activity, we investigated the influence of oxy and deoxy reversibly sickled cells (rsc) ass well as isc on clottin ... | 1981 | 7248527 |
| dietary and hormonal regulation of urea cycle enzymes in rat liver. | when 6-week-old rats fed normal diet (22% protein) were transferred to 10 and 75% protein diet, the levels of urea cycle enzymes showed decreases and increases respectively. the activities expressed as units per gram wet weight of liver had not stabilized after 7 days on the new diet; the corresponding specific activities were closer to leveling off. four daily injections of cortisol raised cps, ass, and arginase. the percentage increases were greater on a 10 than on a 75% protein diet. adrenale ... | 1981 | 7250092 |

| a biochemical comparison of the in vitro replication of a virulent and an avirulent strain of venezuelan encephalitis virus. | the virulent venezuelan equine encephalitis (vee) virus strain, trinidad donkey (trd) and its vaccine derivative strain tc-83, demonstrated biological and biochemical differences in their replication. these two viruses had similarly shaped growth curves; however, trd virus-infected cells produced significantly more infectious virus than did the tc-83 virus-infected cells during the very early period of the replication cycle. trd virus inhibited host cell protein synthesis in vero cells earlier t ... | 1983 | 6842187 |
| cortical infarction in rabbits with serum sickness following cyclosporin a therapy. | rabbits given acute serum sickness (ass) and treated with cyclosporin a (cya) developed glomerular capillary thrombosis and cortical infarction. these lesions were associated with severe endothelial injury and platelet-fibrin-leucocyte thrombi. they were not seen in untreated rabbits with ass, nor in normal rabbits given cya alone in equivalent doses. a similar renal lesion has been reported in patients receiving cya following bone marrow transplantation. | 1983 | 6657686 |
| infectivity of sarcocystis from donkey for horse via sporocysts from dogs. | the dog is the final host for sarcosporidia cysts from the oesophagus and diaphragm of donkeys from sardinia. the prepatent period lasted 9 to 10 days. sporocysts measured 12.2-13.8 x 9.2-9.9 microns. infection of a horse with 10(5) donkey/dog sporocysts increased the rectal temperature to more than 40 degrees c on days 10 and 20 after infection. on day 138 p.i. predominantly immature cysts containing metrocytes were found, especially in the oesophagus. infection on day 117 p.i. with 2 x 10(5) h ... | 1983 | 6410602 |
| the use of heterologous radioimmunoassays for the measurement of follicle-stimulating hormone and luteinizing hormone concentrations in horse and donkey serum. | heterologous double-antibody radioimmunoassay were developed for the measurement of fsh and lh concentrations in the serum of both horses and donkeys. the fsh assay employed a rabbit anti-ovine fsh serum which showed a complete lack of cross-reaction with equine chorionic gonadotrophin (ecg) and negligible cross-reaction with equine lh. the lh assay utilized an antiserum raised against highly purified ecg. this similarly showed negligible cross-reaction with equine fsh but its high cross-reactiv ... | 1983 | 6418846 |
| analysis of competition for substrate sites in an allosteric enzyme with co-operative kinetics. effects of damp and dump on donkey spleen deoxycytidylate aminohydrolase. | hypotheses about the interactions of effectors with conformations of allosteric enzymes having co-operative kinetics can be tested simply and exactly without knowledge of the nature of the intersubunit co-operativity by using a linkage approach to the analysis of steady-state kinetics. applying this approach to competition for substrate sites in the allosteric enzyme donkey spleen dcmp aminohydrolase, we show that the kinetics are consistent with the hypothesis that the substrate dcmp and the co ... | 1983 | 6662104 |
| hormonal regulation of two urea-cycle enzymes in cultured foetal hepatocytes. | foetal-rat hepatocytes were cultured in primary monolayer culture, and activity changes of argininosuccinate synthetase (ass, ec 6.3.4.5) and argininosuccinase (asl, ec 4.3.2.1) were followed under defined hormone conditions. in hormone-free medium, cultured cells maintained the enzyme activities at values equal to those of freshly isolated cells for at least 3 days. continuous addition of dexamethasone produced the development of the two enzyme activities, but only after the first 20h of cultur ... | 1983 | 6661196 |
| differentiation of meat according to species by the electrophoretic separation of muscle lactate dehydrogenase and esterase isoenzymes and isoelectric focusing of soluble muscle proteins. | species identification of fresh meat can be readily achieved by serological techniques with the limitation that closely related species, such as sheep/goat, cattle/buffalo and horse/donkey, cannot be differentiated. we have examined electrophoretic techniques with particular reference to the identification of meat from closely related species. the results showed that beef and buffalo meat and meat from red and grey kangaroos could be clearly distinguished by isoelectric focusing on polyacrylamid ... | 1983 | 6838437 |
| estimation of 14c-triolein assimilation from postprandial serum radioactivity of 14c. | in an attempt to establish a test of lipid assimilation, based on the measurement of the postprandial serum radioactivity of 14c from ingested 14c-triolein, the activity of 14c was measured in serum samples, drawn 1,2,3,4,6 and 9 h after ingestion in 48 consecutive patients suspected of malassimilation. simultaneously, faecal excretion of 14c was measured to estimate 14c-triolein assimilation (f-14c-ass). f-14c-ass served as reference of 14c-triolein assimilation. the sum of the 2- and 4-h serum ... | 1983 | 6648327 |
