Effects of elastatinal, a protease inhibitor, on DNA repair and its cytotoxicity were investigated in normal human, xeroderma pigmentosum and Chinese hamster V79 cells. There were no effects of elastatinal on DNA repair and UV-induced sister chromatid exchanges, and all

Elastase plays an important role in wound healing process, degrading damaged tissue and allowing complete tissue recovery. The levels of human neutrophil elastase (HNE) are usually controlled by endogenous inhibitors. However, in the presence of high levels of elastase, like
Microbial protease inhibitors elastatinal and leupeptin were tested for cytotoxicity and for effects on spontaneous and u.v.-induced 6-thioguanine-resistant (6TGr) mutation and sister-chromatid exchange (SCE) in V79 Chinese hamster cells. Continuous treatment with elastatinal exhibited marked cytotoxicity, while leupeptin was almost

Scutellarin is a flavonoid extracted from a traditional Chinese herb, Erigeron breviscapus. The present study investigated the effect of scutellarin on MUC5AC mucin production and the possible mechanism. Human bronchial epithelial 16 (HBE16) cells were pretreated with scutellarin for 60

The extracts of granules isolated from bovine granulocytes show elastase- and chymotrypsin-like activities, as detected with specific synthetic substrates. Extraction of these enzymes depends upon salt concentration. In the course of the present studies a 21-fold purification of the elastase-like
