Abstract:
OBJECTIVE： To investigate the acute toxicity， long-term toxicity， skin irritation and anaphylaxis of Bee venom （BV） plastics， and to evaluate its preclinical safety. METHODS： The acute toxicity of BV plastics to rats was investigated after administration of high-dose， medium-dose and low-dose （144， 96， 48 mg/kg） of BV plastics. The long-term toxicity of BV plastics was investigated by continuous administration of high-dose， medium-dose and low-dose （72， 48， 24 mg/kg） of BV plastics for 28 days. The irritation of intact and damaged skin in rabbits with 8 mg/kg BV plastics was investigated by using the self-control method of left and right homologous body. The skin anaphylaxis of guinea pig were investigated after sensitized with 15 mg/kg BV plastics on the left back （on 0， 7th， 14th day） and stimulated with 15 mg/kg BV plastics on the right back. RESULTS： During the acute toxicity experiment with BV plastic，the weight of rats and the changes of viscera were normal，and there was no relevant toxic reaction. Long-term toxicity test results showed that no significant pathological changes were observed at 24 h after the last administration； the spleen index of rats in BV low-dose group， testicular index in middle-dose group and epididymis index in high-dose and middle-dose groups were significantly increased， while PT in plasma of rats in BV medium-dose and low-dose groups was significantly prolonged （P＜0.05）. There were no abnormal changes in organ appearance， other organ index， coagulation index and blood biochemical index. All above indexes became normal at the end of 2-week recovery period. Skin irritation test showed that BV plastics could cause slight erythema and obvious scab on the skin of rabbits which along with little irritation on intact or damaged skin. Skin anaphylaxis test showed that BV plastics produced mild erythema in the skin of guinea pigs， belonging to light allergy. CONCLUSIONS： No acute or long-term toxicity is observed after transdermal administration of BV plastics， which is safe and only causes mild irritation and irritability to skin， indicating there is good safety of the plastic under experiment doses.
