This study was to evaluate the effects of oral administration of Processed Sulphur on Hepatotoxicity. Processed Sulphur was administered orally to rats for 28 days. We measured the body and liver weight index, heamtological and biomedical parameters. We also observed the histopathological changes of liver in rats. No significant differences in body weight, liver weight index, heamtological and biomedical parameters and histopathological changes of hepatocyte between control and Processed Sulphur fed group were found. Our data indicate that hepatotoxicity was not caused by oral medication of Processed Sulphur up to 60mg/200g/day for 28 days in rats. Therefore, Processed Sulphur appears to be safe and non-toxic in these studies and a no-observed adverse effect level (NOAEL) in rats is established at 60mg/200g/day. The data could provide satisfactory preclinical evidence of safety to launch clinical trial on standardized formulation of mineral extracts.

Edible hardened soybean oil is processed by hydrogenation of refined soybean oil in order to upgrade the heat and oxidation stability and to improve flavor and physical nature. This study aims to investigate the influences of various reaction conditions on iodine value, fatty acid composition and trans isomer formation in hydrogenating soybean oil. In case that hardening temperature is $180^{\circ}C$, trans acid formation increased by 6.2 times more under $3.0{\;}kg/cm^{2}H_{2}$ than under $0.5{\;}kg/cm^{2}H_{2}$, while linolenic acid decreased in contents. In case of $200^{\circ}C$ of hardening temperature trans acid formation showed 4.6% higher under $0.5{\;}kg/cm^{2}H_{2}$ than under $3.0{\;}kg/cm^{2}H_{2}$ while contents of linolenic and linoleic acids showed 0.51% and 2.5% lower respectively. It is concluded that $200^{\circ}C$ of hardening temperature under 0.5 and $3.0{\;}kg/cm^{2}H_{2}$ is better condition because trans isomers are little produced, and iodine value and linolenic acid content decreased in hardening soybean oil.
