圈养条件下亚成体雌性金钱豹肺微血管铸型的扫描电镜观察

<正>金钱豹(Panthera pardus)属国家一级重点保护野生动物。关于人(Homo sapiens,真炳攸等,1990)、鼠(Ferrieira et al.,2001)、家兔(俞诗源和李重阳,1995)、牦牛(Bos grunniens,柳东阳,2007)、绵羊(Schraufnagel et al.,1995)、川金丝猴(Rhinopithecus roxellanae,俞诗源,1997)和双峰驼(Camelus bactrianus,Yu et al.,2004;Zhao et al.,2005)等动物肺的微血管构成情况已有报道。金钱豹作为大型食肉兽,体格强健,行动敏捷,能跳善爬,其肺应具有更加完善的结构特征

An SEM observation of the microvascular casts of the lungs of a subadult female leopard (Panthera pardus)in captivity

The present study was conducted to investigate the microvascular structures of a case of subadult female leopard (Panthera pardus)that had died from wound in captivity,by using the microvascular casting method to provide useful information and evidence to the study of respiratory physiology in animals. The results observed through the scanning electron microscope (SEM)indicated that the arterioles of the lung and pleura are formed by the ramification of small arteries (0.3 -1.0 mm diameter),pre-capillary arterioles (11 - 15 μm diameter),and capillaries (4.5 - 7.0 μm diameter). There are extensive connections in capillarity networks of blood vessels,including bridge connections between adjacent alveoli holes that form the irregular alveolar-capillary network. Our findings suggest that the dense and stereo capillary network is an important feature of the lung microvasculature in snow leopard,and is similar to those in human,mouse,rabbit,yak, sheep,Sichuan snub-nosed monkey and bactrian camel,but different from those in birds,reptiles,and amphibians.
