Carcinogenicity studies on halogenated hydrocarbons.
A series of halogenated compounds was tested by oral intubation in 200 Osborne-Mendel rats and 200 B6C3F1 mice of both sexes. Carbon tetrachloride, used as a positive control, induced liver and adrenal tumors in mice and neoplastic nodules in the livers of rats. 1,2-Dibromoethane and 1,2-dibromo-3-chloropropane caused stomach tumors with many metastases in both rats and mice. Chloroform, known ...
متن کاملCasein Viscosity Studies
1. Viscosity and pH curves of casein dissolved in NaOH, KOH, LiOH, and NH(4)OH are shown and it is found that a maximum viscosity occurs at about the same pH point with each alkali; i.e., 9.1 to 9.25. The magnitude of the viscosity is largest in ammonia solutions. 2. The maximum viscosity occurs in 8 to 10 per cent solutions of casein in alkalies when about 98 x 10(-5) gram equivalents of base ...
متن کاملStudies in the Action of Trypsin. I. on the Hydrolysis of Casein by Trypsin
The mode of operation of this reaction is entirely beyond the category of our present knowledge. The researches of Emil Fischer’ on the hydrolysis of the synthetic polypeptides will, it is hoped, throw some light on this question, for many of these synthetic products are known to be hydrolyzed by trypsin. It has been found that this reaction proceeds at all temperatures in neutral watery soluti...
متن کاملBiochemical studies on the metabolic activation of halogenated alkanes.
This paper reviews recent investigations by Slater and colleagues into the metabolic activation of halogenated alkanes in general and carbon tetrachloride in particular. It is becoming increasingly accepted that free radical intermediates are involved in the toxicity of many such compounds through mechanisms including lipid peroxidation, covalent binding, and cofactor depletion. Here we describ...
