We have made survey on ecological aspects of the venomous snakes in Guangxi Zhuan Autonomous Region, China.In Ziyuan district, northenmost area of Guangxi, we have checked the possibility of the presence of Agkistrodon sp, because there were several snake-bite cases considered to be Agkistrodon bite by some authorities.Although we have found many snakes, lizards and frogs whose affinities are northern areas from Guangxi, we have failed to find Agkistrodon.The medical staffs of the District have agreed to continue the survey in future and retain the specimens for the future investigation.As for the distribution of two species of green pit vipers, Trimeresurus albolabris has been shown to occur in northern Guangxi and Guizhou, and very common in southern Guangxi.T.stejnegeri may be more common in montanus area.On the other hand, T.mucrosquamatus is very common in northern area as Ziyuan.The staffs of Fangcheng also agreed to retain the specimens causing the bite and make it possible to check the symptoms with actual snake for the case.In Beihai area, several seasnake bites occur annualy, and no antivenom is available in China presently.Guangxi Medical University has an idea to produce antivenom in future, and we have tried to collect venom from the heads cut off during cooking for seasnake dish and quite successful to obtain good venom to immune.The most abundant species in the shore of Beihai is Lapemis curtus, and Hydrophis cyanocinctus is the next.In Longzhou, the area of Vietnamese border, we have found a new species of the genus Boiga.Only three specimens are retained by the Guangxi Medical University, and will be described in the near future.The venom of Naja atra is less potent than other species of Naja in Southeast Asia, and cause more necrosis under skin which occur immediately after the bite and the antivenom tends to be late.

我们对广西壮族自治区毒蛇的生态方面进行了调查。在广西最北端的自源区，我们已经检查了蝮蛇属存在的可能性，因为有几例被一些当局认为是蝮蛇咬伤的蛇咬伤病例。虽然我们发现了许多与广西北部地区有亲缘关系的蛇、蜥蜴和青蛙，但我们没有发现蝮蛇。该区医务人员同意今后继续调查，并保留标本供今后调查之用。在两种绿坑蛇的分布上，Trimeresurus albolabris主要分布于广西北部和贵州，在广西南部非常常见，而t .stejnegeri可能在山区更为常见。另一方面，在紫源等北部地区，长鳞田鼠十分常见。方城的工作人员也同意保留引起咬伤的标本，以便能够与实际的蛇进行症状检查。在北海地区，每年都会发生几起海蛇咬伤事件，目前国内没有抗蛇毒血清。广西医科大学有一个未来生产抗蛇毒血清的想法，我们尝试从烹制海蛇时切下的蛇头中提取蛇毒，并取得了很好的免疫效果。北海沿岸最丰富的种类是蓝齿海螺，其次是蓝齿海螺。在越南边境龙州地区，我们发现了一种新的Boiga属植物。广西医科大学只保留了三个标本，并将在不久的将来进行描述。与东南亚其他种类的那加蛇相比，那加蛇的毒液效力较弱，并且在被咬后立即引起皮肤下的坏死，而抗蛇毒血清往往较晚。
