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.

我们对中国广西壮族自治区的毒蛇进行了生态方面的调查。在广西最北端的资源区，我们检查了蕙蛇存在的可能性，因为有几起蛇咬伤事件，一些权威机构认为是蕙蛇咬伤。尽管我们发现了许多与北方地区有亲缘关系的蛇、蜥蜴和青蛙， 广西，我们未能找到蕙蛇。该区医务人员已同意今后继续调查，并保留标本以备将来调查。至于两种绿蝮蛇的分布情况，白花竹叶青已被证明分布于广西北部和贵州，在桂南地区很常见。竹叶青可能在山地蝰中更常见。 另一方面，粘鳞T.mucrosquamatus在北方地区如资源地区很常见。防城的工作人员也同意保留引起咬伤的标本，以便可以用真蛇来检查症状。北海地区每年都会发生多起海蛇咬伤事件，而目前国内还没有抗蛇毒血清。广西医科大学有一个想法，未来将生产抗蛇毒血清，并且 我们曾尝试从海蛇菜烹饪过程中割下的头中收集毒液，并取得了很好的免疫效果。北海沿岸种类最多的是Lapemis curtus，其次是Hydrophisyanocinctus。在越南边境的龙州地区，我们发现了Boiga属的一个新物种。广西医科大学仅保留了三个标本，将在下面介绍 在不久的将来。与东南亚其他种类的眼镜蛇相比，眼镜蛇的毒液效力较弱，并且会导致更多的皮下坏死，这种情况在被咬后立即发生，并且抗蛇毒血清往往会延迟。
