ABSTRACT
The aim of the experimental study is to investigate shortterm toxicity of an initial domestic Methotrexate microspheres(MTX-ms)by hepatic arterial infusion in rats,provide some experimental bases for clinic interventional treatment of liver carcinoma with this new chemoembolization agent.Compareing with control group and MTX group, MTX-ms of largedoses could result in temporal rise of GPT and AKP,deterioration or necroses of animal's liver at different degrees,12 days later a number of microspheres could still be found in the small arteries of the necrotizing area.No pathological changes related to microsphere could be found in other main organs(heart,spleen,lung and kidney).Results suggested that chemoembolization effect of MTX-ms is relatively strong;for effectively oc- cluding blood flow of hepatic arteries on the level of small arteries.Meanwhile MTX-ms oc- clud blood supply of liver carcinoma,they may also cause damages of normal liver tissue. Clinically more attention ought to be paid to the dosage of MTX1 microspheres and thus avoid the overflow of more microspheres to the normal liver tissue causing damage.
