chymotrypsin/edema

OBJECTIVE To assess the intraoperative and postoperative clinical effects and histologic effects of intracameral administration of α-chymotrypsin in clinically normal dogs undergoing standard intracapsular lens extraction (ICLE). METHODS 6 young adult male dogs without evidence of systemic or ocular

The protective antigen (PA) component of anthrax toxin contains two sites that are uniquely sensitive to proteolytic cleavage. Cleavage at the sequence RKKR167 by the cellular protease furin is absolutely required for toxicity, whereas cleavage by chymotrypsin or thermolysin at the sequence FFD315

Three phospholipase A2 enzymes or homologs were purified from the venom of Trimeresurus mucrosquamatus (Taiwan habu). The most abundant one was found to be a phospholipase homolog without enzyme activity, and its complete amino acid sequence was determined using oligopeptide fragments derived from

Trimucase II, a proteolytic enzyme isolated from Trimeresurus mucrosquamatus venom, caused rat hind-paw edema dose dependently. Captopril potentiated significantly, while pretreatment with cellulose sulfate suppressed the trimucase II-induced edematous response. Pretreatment with diphenhydramine and

A serine proteinase inhibitor isolated from Leucaena leucocephala seeds (LlTI) was purified to homogeneity by acetone fractionation, ion exchange chromatography, gel filtration and reverse phase chromatography (HPLC). SDS-PAGE indicated a protein with M(r) 20000 and two polypeptide chains

Ticks inject serine protease inhibitors (serpins) into their feeding sites to evade serine protease-mediated host defenses against tick-feeding. This study describes two highly identitical (97%) but functionally different Amblyomma americanum tick saliva serpins (AAS41 and 46) that are secreted at

Ex vivo canine lung lobes were exposed to a pancreatic proteolytic enzyme (chymotrypsin) alone or chymotrypsin after pretreatment with a continuous infusion with pentoxifylline. The lobes exposed to chymotrypsin gained 133 g, while the pentoxifylline-treated lobes gained only 65 g (p less than .05)

Several species of Culicoides biting midges are important pests and vectors of pathogens affecting humans and other animals. Bluetongue is the most economically important arthropod-borne animal disease in the United States. Culicoides variipennis is the primary North American vector of the

The effects of chronic administration of methamphetamine on pancreatic tissues were histopathologically studied in experimental models. Methamphetamine (1 ml/kg body weight/day) was subcutaneously injected into 14 five-week-old male Wistar Kyoto rats (WKY) for 12 weeks. Age and sex matched 5 WKY
