Long lasting effects of perinatal ethanol exposure were studied in adult rats who were the offspring of dams fed a 5.0% w/v ethanol-containing liquid diet ad libitum or pair-fed the isocaloric control diet during gestation weeks 2 and 3 or during postnatal week 1. Fetal exposure to ethanol reduced body weight of pups at birth unless the ethanol diet was supplemented with casein; neonatal exposure to the ethanol or pair-fed diets, casein supplemented or not, reduced pup weights until day 21 postnatally when weights of all fetally or neonatally exposed pups were normal. Between 52 and 120 days of age females were tested for pituitary-adrenal and temperature responses to a challenge dose of ethanol. Prenatally ethanol-exposed rats showed significantly higher plasma corticosterone titers and developed a greater hypothermia in response to an intraperitoneal injection of ethanol (0.75--1.5 g/kg) than did pair-fed controls. Similar responses enhancement did not occur in the postnatally ethanol-exposed rats. Temporal patterns of blood ethanol levels after an intraperitoneal injection of ethanol (1.5 g/kg) were similar in prenatally ethanol-exposed females and their pair-fed controls. The data indicate that exposure to ethanol in utero exerts persistent effects on the offspring, rendering them more responsive to the hypothermic and pituitary-adrenal activating effects of alcohol as adults.

Changes in body temperature and cell infiltration, mediated by cytokines including tumor necrosis factor-alpha (TNF-alpha), occur during inflammation, but a role of body temperature on inflammatory responses remains obscure. Intraperitoneal injection of 10% casein to mice resulted in transient hypothermia followed by neutrophil accumulation in peritoneal cavities. Peritoneal TNF-alpha was rapidly raised, and pretreatment of mice with an anti-TNF-alpha antibody promoted temperature restoration and partially inhibited neutrophil accumulation. To investigate direct effects of body temperature on neutrophils, peritoneal or peripheral blood neutrophils were cultured at 35 degrees C or 37 degrees C with or without recombinant murine TNF-alpha (100 ng/ml) or a protein synthesis inhibitor cycloheximide (1 microg/ml). Significant inhibition of spontaneous and TNF-alpha-induced apoptosis was obtained at 35 degrees C compared with 37 degrees C, an effect that was not altered by the addition of cycloheximide. Moreover, phagocytic ability of peritoneal neutrophils was significantly enhanced by incubating them at the lower temperature. These results indicate that mild hypothermia induced by endogenous TNF-alpha has enhancing roles on neutrophil survival and function during peritoneal inflammation.
