Abstract:
3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX)was administerd to Wistar rats(1.65,165,16500 ng/kg) by gavage one time a day for 15 days.At the end of this period, significant increases of sperm abnormality rate were observed in rats exposed MX at certain doses.Organ index of liver and kidney were changed and pathological changes took place.No signficant increases of micronucleus induction in polychromatic erythrocytes (PCEs)of bone marrow and lipid peroxidation(LPO)level in serum and tissue(live,kidney and testicle)of rats were showed. Our results suggested that MX was able to induce genotoxicity of reproductive cells and to injure the liver and kidney of rats exposed.But no oxidative damage was found.

Abstract(1112)
Abstract:
To examine the hepatoprotecive effects of Gly cyr rhizin(GL) and Oleanolic acid(OA)against Cadmium(Cd)-induced liver injury in rats and the mechanisms of protection,SD rats were injected ip with CdCl2(0.8mg/kg Cd2+/kg body weight,five times a week).Two cadmium-challenged groups were concomitantly injected sc with GL(20mg/kg,three times a week)and OA(60mg/kg,five times a week)respectively.Serum activities of alanine aminotransferase(ALT)and aspartate aminotr ansferase(AST)indicative of hepatic injury were measured,and livers were examined mor phologically and analyzed for cadmium and metallothio nein (MT).Bo th GLand OA delayed and attenuated the elevation of serum ALT and AST activities,ameliorated hepatic parenchymal swelling and necrosis produced by cadmium.Electron microscopy showed the pathological changes of hepatocellular mitochondr ia and smooth endo plasmic reticulum were less severe in Cd-GL,CdOA-cotreated rats compared with Cd-treated ones.In the early stage of cadmium exposure,GLnd OA also decreased hepatic cadmium accumulation and increased hepatic MT induction,which in turn elevated MT amount available to every cadmium unit.It show s that both GLand OA can protect rats against Cd-induced hepatotoxicity in subchronic Cd exposure.The protection may be in partrelated to decrease of cadmium accumulation and additional increase of MT induction in the target or gan.

Abstract(1029)
Abstract:
Five groups of SD male rats were provided with deionized drinking water containing 0 and 150mg/L NaF,and containing both 150mg/L NaF and 0.5,2.0 or 4.0mg/L Na2SeO3 respectively for 10 weeks,in order to observe the effects of different concentrations of selenite in drinking water on the urinary excretion of fluoride and renal damages induced by 150mg/L NaF,and find out the optimal level of selenite in drinking water against fluoride toxicity.The results showed that fluoride could cause the significant elevation of fluoride ion levels in serum and urine of rats exposed to fluoride in drinking water and the obvious renal damages in patholoyg,enzyme histochemistry and ultrastructure.2.0mg/L Na2SeO3 in drinking water induced the most obvious acceleration of fluoride excretion in urine and possessed the most significant antagonistic effects on the renal impairments induced by 150mg/L NaF,those of 0.5mg/L Na2SeO3 were not evident,whereas 4.0 mg/L Na2SeO3 appeared to be toxic to kidney.Thus it is concluded that 2.0mg/L Na2SeO3 is the optimal concentration for the antagonistic effect on renal impairments induced by 150mg/L NaF in drinking water.
