Effect of dietary vitamin E on expiration of pentane and ethane by the rat

摘要: An analytical method for the measurement of hydrocarbon gases in breath rats is described. The was used to follow expiration rat vivo formed scission products hydroperoxides. major are pentane from linoleic acid family and ethane linolenic family. Rats were fed 0, 11 or 40 i.u. vitamin E acetate/kg diet 7 wk starting at age 21 days. Data obtained by gas chromatographic analysis samples analyzed Mann-Whitney nonparametricU-test. This statistical showed that evolved group not supplemented with significantly higher during period 1–7 than either two groups rats. Ethane nonsupplemented E/kg 5 wk, both 6 wk. By production tenfold greater group, about twofold greater. There no significant difference between pentane. new technique, which measures lipid peroxidation, promises be useful application many experimental areas where peroxidation expected known occur.
