The gelatinolytic activity of human skin fibroblast collagenase.
The gelatinolytic activity of human skin fibroblast collagenase was examined on denatured collagen types I-V. All denatured substrates were cleaved, including types IV and V, which are resistant to collagenase in native form. Interestingly, the earliest major cleavage in denatured collagen types I-III occurred at a 3/4-1/4 locus, resulting in products electrophoretically identical with TCA and ...
متن کاملAlkaline phosphatase activity in the rat uterus.
A COMPARATIVE study of the distribution of placental scars from the first and second pregnancies in laboratory rats indicated that the most posterior scar of first pregnancy tends to be nearer to the cervix than the most posterior second pregnancy scar (Momberg & Conaway, 1956). Frazer (1955) in an earlier study observed that more embryos implanted in the caudal half of the uterus of the rat th...
متن کاملSpasmolytic Activity of Piper Nigrum Fruit Aqueous Extract on Rat Non-Pregnant Uterus
Black pepper ( Piper nigrum ) from Piperaceae and its main ingredient (piperine) reduces gastric emptying in rats. In Iranian traditional medicine, black pepper is used to relief the menorrhalgia in women. The aim of this study was to investigate the effect of black pepper fruit aqueous extract on non-pregnant rat uterus contractions and the mechanism(s) of its action. To prepare the extract, b...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولTotal, latent and active collagenase during the course of post-partum involution of the rat uterus. Effect of oestradiol.
1. Total, active and latent collagenase activities were determined by direct assay of tissue homogenates. 2. The rate of collagen breakdown during post-partum involution of the rat uterus is correlated with the total activity of collagenase. Both are low at parturition, reach a maximum within 24h and fall slowly to low values of 5 days post partum. This temporal correlation strongly supports th...
