| partial purification of prolactin-like substance from snake (ptyas mucosa) pituitaries. | pituitary extract of the common rat snake (ptyas mucosa) was found to be capable of displacing the binding of 125i-labelled ovine prolactin to female rat liver membranes, suggesting the presence of prolactin-like substance in snake pituitary. the snake prolactin-like substance was unadsorbed on concanavalin a-sepharose, but adsorbed on deae-cellulose. the partially purified snake prolactin-like substance was also capable of displacing the binding of 125i-labelled ovine prolactin to snake kidney ... | 1990 | 2101786 |
| beta-endorphin-like and adrenocorticotropin-like hormones in the pituitary of the snake ptyas mucosa. | snake (ptyas mucosa) pituitaries were heated, extracted with an acidic medium, and the extract subsequently chromatographed on carboxymethyl cellulose (cmc). fractions were assayed for their abilities to displace d-ala2-d-leu5-[tyrosyl, 3,53h] enkephalin from binding to rat brain membranes and 125i-beta-endorphin from binding to its antibody, and to stimulate corticosterone production by isolated rat adrenal cells. the fraction unadsorbed on cmc (having the least basic character) had the lowest ... | 1990 | 2164396 |
| adrenocorticotropin- and beta-endorphin-like substances in brains of the freshwater snake ptyas mucosa. | snake (ptyas mucosa) brains (400 g) were extracted with a mixture of acetone, water, and hydrochloric acid. the precipitate (5.6 g) that formed upon addition of five volumes of acetone to the extract, designated acid-acetone powder, was subjected to gel filtration on sephadex g-25. a large unretarded peak (sb-1) with molecular weight greater than 5000 and a small retarded peak (sb-2) with molecular weight smaller than 5000 were obtained. they were then separately subjected to ion-exchange chroma ... | 1990 | 2171578 |
| presence of prolactin receptors in kidney and large intestine of the snake ptyas mucosa. | 125i-labeled ovine prolactin was used to test for the presence of prolactin receptors in membranes prepared from tissues of the common rat snake ptyas mucosa. high levels of specific binding were found in kidney and large intestine membranes prepared from snakes of both sexes. the binding was time, temperature, and protein dependent. the presence of ca2+ in the incubation medium enhanced the binding, with optimal concentrations at 10-20 mm. specificity of binding was established by employing dif ... | 1990 | 2272458 |

| study on the purification of growth hormone-like substance from pituitaries of the snake ptyas mucosa. | extract from the snake (ptyas mucosa) pituitaries was capable of inhibiting the binding of 125i-labelled bovine growth hormone to female rat liver membranes. the growth hormone-like substance was not adsorbed on concanavalin a-sepharose nor deae-cellulose, but could be purified by gel filtration on sephadex g-50. it possessed a molecular weight of about 19,000 as judged by sds-polyacrylamide gel electrophoresis. the iodinated snake growth hormone-like substance bound to membranes prepared from f ... | 1993 | 8361955 |
| immunohistochemistry and tinctorial affinity of adenohypophysial cells of the rat snake ptyas mucosus (colubridae). | immunocharacteristics of the adenohypophysial cells of the rat snake ptyas mucosus (colubridae) were studied with an unlabeled antibody enzyme technique (pap method) using rabbit antisera against mammalian/synthetic hypophysial hormones. adenohypophysial cells were identified on the basis of their specific immunoreactivity with various heterologous antisera. as in other reptiles, there was regional localization of pars distalis (pd) cell types in this snake. the gonadotropic (gth) cells were ide ... | 1997 | 9073492 |
| characterization of novel dna-binding proteins expressed in snake oocyte cdna library. | dna-binding proteins play pivotal roles in transcription, dna-replication, recombination/repair and determine cell-fate in all physiological conditions of differentiation, development and disease. as they are present in extremely small amounts in cells, their isolation/identification, particularly from scarce tissues is impracticable. we cloned the cdna pool of snake (ptyas mucosus) oocytes (a scarce tissue) in bacteria, overexpressed total library, purified and identified dna-binding proteins e ... | 2007 | 17189702 |
| evaluation of hypoglycemic and anti-hyperglycemic potential of tridax procumbens (linn.). | diabetes is a metabolic disorder affecting carbohydrate, fat and protein metabolism. tridax procumbens linn.

| hypotensive actions of snake parathyroid glands. | parathyroid gland extracts from four different snake species, ptyas korros, ptyas mucosa, elaphe radiata, and naja naja, were prepared and their hypotensive actions were assayed in anesthetized p. korros. all extracts were hypotensive and the responses, except that of n. naja, were dose related. their potencies were, however, different in different species. these data suggest that the hypotensive property of the parathyroid hormone is probably widely distributed in submammalian vertebrates. | 1983 | 6667839 |
