The organotin compound, triethyltin (TET), produces toxic effects in a variety of physiological systems. Thermoregulatory control appears to be especially susceptible to TET toxicity, since TET administration has been shown to cause a pronounced hypothermia in rats. To further elucidate effects of TET on thermoregulation, we measured metabolic rate, evaporative water loss (EWL), body temperature, and preferred ambient temperature (Ta) of mice treated intraperitoneally with TET (bromide salt). At a Ta of 23 to 24 degrees C, TET (6 and 8 mg/kg) inhibited metabolic rate by 23 and 66%, respectively. TET resulted in hypothermia at Ta's of 20 and 30 degrees C but not 35 degrees C. TET had little effect on EWL. Mice given TET at doses of 4, 6, and 8 mg/kg selected a cooler Ta (ca. 25 degrees C) compared to controls (ca. 29 degrees C). Thus, the mice selected a Ta associated with a hypothermic body temperature. At a relatively cool Ta, mice treated with TET had a reduced rate of heat production and, consequently, were hypothermic. At a relatively warm Ta, TET had no effect on heat production and did not increase active heat dissipation (i.e., EWL), thus the mice remained normothermic. The behavioral data indicate that TET evokes a type of regulated hypothermia in mice.
