The present study investigated the toxic effects of B. lienhardi venom, at the histological, hematological, biochemical and motor skill levels following a subcutaneous injection of different doses of venom. The LD50 of B. lienhardi scorpion venom was found to be 0.27 mg/Kg by subcutaneous injection route. The results clearly indicate that B. lienhardi venom induces massive tissue damages in the organs, such as lungs, heart, kidneys and liver together with hematological impairments manifested by decreased levels of both red and white series. We further demonstrated that scorpion venom is able to alter motor system by inducing motor incoordination and reducing muscle strength. The overall results confirm that the venom from B. lienhardi primarily is a highly toxic agent and has cardiotoxic, nephrotoxic, hepatotoxic and pneumotoxic activity.
本研究在皮下注射不同剂量毒液后,从组织学、血液学、生物化学和运动技能水平方面,研究了李氏蝎毒的毒性作用。通过皮下注射途径发现李氏蝎毒的半数致死量为0.27毫克/千克。结果清楚地表明,李氏蝎毒会在肺、心脏、肾脏和肝脏等器官中引起大量组织损伤,同时伴有血液学损伤,表现为红细胞和白细胞水平降低。我们进一步证明,蝎毒能够通过引起运动不协调和降低肌肉力量来改变运动系统。总体结果证实,李氏蝎毒主要是一种剧毒剂,具有心脏毒性、肾脏毒性、肝脏毒性和肺毒性活性。
