our previous experiments indicated that smooth muscle cells (SMC) in neointima of injured rabbit aorta (a) acquire the capacity to produce PGI2 and (b) have increased lysosomal CE hydrolytic (acid cholesteryl ester hydrolase [ACEH])activity. Using cultured SMC from rabbit thoracic aorta, we demonstrated that PGI2, 6-keto-PGF1,, and 6-keto-PGE, enhanced ACEH activity fourfold. No significant eff...

the purpose of this study was to evaluate the effects of scrophularia striata water extract on the quality and shelf life of the rainbow trout fillet during superchilled storage. fish samples were treated with 1% and 3% s. striata water extract and then stored at -2°c for 20 days. the samples were analyzed periodically for chemical, microbial and sensory characteristics. results indicated that ...

The hydrolytic reactions of esters and amides of thiosulphurous acid ate investigated in a homogeneous medium. The esters are hydrolysed by alkali to gire sulphide, sulphite and thiosulphate whereas the amides are resistant towards alkali. Both the esters and amides are hydrolysed by acids giving hydrogen sulphide, sulphur dioxide, polythionates and elemental sulphur. The hydrolysis of these es...

Certain strains of Moraxella bovis produce tissue-damaging enzymes which may initiate or potentiate infectious bovine keratoconjunctivitis. Thirteen reference strains of this species were characterized physiologically and screened for production of various enzymes by some conventional biochemical tests and the API ZYM system (Analytab Products, Plainview, N.Y.). All 13 strains were hemolytic. A...
