The Bromination ofp-Nitrophenol in Acetic Acid

0~ the Decomposition Ofp-oxybutyric Acid and Aceto-acetic Acid by Enzymes of the Liver

There is one respect in which almost all workers who have attacked the problem of fatty acid catabolism are agreed. The hypothesis that the higher fatty acids when undergoing decomposition in the animal body may part successively with groups containing two carbon atoms with resulting formation of lower fatty acids is practically unanimously accepted.’ This series of changes in the case of a typ...

Enzymic Sulphation ofp-Nitrophenol and Steroids by Larval Gut Tissues of the Southern Armyworm (Prodenia

1. An enzyme system that catalyses the sulphation of p-nitrophenol, cholesterol, a-ecdysone, fi-sitosterol, dehydroepiandrosterone, oestrone and four other steroids of plant and insect origin was obtained from the soluble fraction of southern-armyworm gut tissues. 2. The enzyme system required ATP and inorganic sulphate, and activity was slightly enhanced in the presence of GSH. 3. The properti...

Acetic Acid in Cholera

The treatment of cholera by acetic acid, suggested by Dr. Greene in the September number of the Indian Medical Gazette, deserves, I think, to be put to the test by the profession. When I perused Dr. Greene's article, it struck me that, from its strong antiseptic property, acetic acid may do good by counteracting the morbific influence of the cholera miasm in the blood. Besides, being a stimulan...

The effects of crocin, mesalazine and their combination in the acetic acid-induced colitis in rats

Crocin, as a carotenoid compound of saffron, exerts a potent antioxidant property. Mesalazine is frequently used in the treatment of ulcerative colitis. This study investigated the effects of separated and combination treatments with crocin and mesalazine in a rat model of ulcerative colitis. Ulcerative colitis was induced by intra-colonic administration of acetic acid (4.00%, 1.00 mL) at 8 cm ...
