Heat stroke is a potentially fatal disorder that's caused by an extreme elevation in body temperature. We report here an unusual case of multiple organ failure that was caused by classical, nonexertional heat stroke due to taking a warm bath at home. A 68 year old diabetic man was hospitalized for loss of consciousness. He was presumed to have been in a warm bath for 3 hrs and his body temperature was 41 degrees C. Despite cooling and supportive care, he developed acute renal failure, disseminated intravascular coagulation (DIC) and fulminant liver failure. Continuous venovenous hemofiltration was started on day 3 because of the progressive oligouria and severe metabolic acidosis. On day 15, septic ascites was developed and Acinetobacter baumanii and Enterococcus faecium were isolated on the blood cultures. In spite of the best supportive care, the hepatic failure and DIC combined with septic peritonitis progressed; the patient succumbed on day 25.

OBJECTIVETo observe the effect of Gingerol on endotoxemia mouse induced by heatstroke.

METHODSForty mice were randomly divided into five groups, the endotoxemia model group (A), the normal temperature group (B), the Gingerol treated group (C), the solvent control group (D), and the saline control group (E), 8 mice in each group. Group B to E was administered with saline, Gingerol, solvent and saline respectively. Mice in group B were placed at room temperature 25 +/- 0.5 degrees C , relative humidity 43 +/- 5 % for 2 hrs, while mice in the other groups were exposed under 35 +/- 0.5 degrees C and relative humidity 65 +/- 5 % for 2 hrs in an artificial hot-climate mimic cabin to establish heatstroke endotoxemia model. The energy metabolic level of celiomacrophage was detected with MTT; the phagocytic ability was examined with neutral red chromometry; the hepatocyte ultrastructure was observed with transmission electron microscopy, as well as the activity of superoxide dismutase (SOD) and the level of malondialdehyde (MDA) in plasma was tested.

RESULTSAs compared with Group A, D and E, in Group C, energy metabolic levels of macrophage, phagocytic ability, and activity of SOD were significantly higher (P < 0.01), and the level of MDA was significantly lower respectively (P < 0.01), with the levels of SOD and MDA approaching to those in Group B (P >0.05). The pathologic changes of hepatocyte ultrastructure in group C were less than those in the other three endotoxemia groups.

CONCLUSIONGingerol could raise the energy metabolic level of celio-macrophage to enhance its phagocytic ability, increase the activity of SOD and reduce the production of MDA in mouse with heatstroke endotoxemia, so as to alleviate the liver damage.
