Abstract
Chloral hydrate has been found in our drinking water supplies at levels up to 5 micrograms/1. The purpose of this study was to evaluate the functional status of the immune system in random-bred CD-1 mice exposed to chloral hydrate for 14 and 90 days. Male mice, following 14 or 90 days of exposure to 1/10 and 1/100 the actual oral LD50, exhibited no alterations in either humoral or cell-mediated immunity. However, female mice exposed for 90 days to chloral hydrate in the drinking water demonstrated a significant depression in humoral immune function. This depression was observed when spleen cells from exposed mice were evaluated for their ability to produce antibody against sheep erythrocytes. These females did not demonstrate any changes in cell-mediated immune status.
