Frequency and component analysis of contaminants generated in preparation of anticancer agents using closed system drug transfer devices (CSTDs).

Occupational exposure of anticancer agents during their preparation has been recognized as a serious hazard. Closed system drug transfer devices (CSTDs) enable "safe" preparation of agents for medical personnel and ensure a safe hospital environment.

Fructooligosaccharides consumption inhibits the loss of iron from the incisor enamel surface in gastrectomized rat.

We examined the effects of fructooligosaccharides (FOS) on the reduction in the incisor iron content in gastrectomized rat. Twenty-eight 5- wk-old male Sprague-Dawley rats were divided into two groups: sham operated (bSH) and gastrectomized (bGX). After 4 wk, each group was divided into two subgroups according to the presence or absence of 7.
