| histological and immunocytochemical study of deferens ducts in the chinese rat snake (zaocys dhumnades). | to investigate the relationship between structure and function of the deferens ducts in the chinese rat snake (zaocys dhumnades), morphological changes within an annual cycle were observed by routine histological techniques. also, the correlation of androgen receptor (ar), estrogen receptor (er), progesterone receptor (pr) and aromatase (ar) expressions in the vas deferens and testis were studied immunohistochemically. to confirm that the sperm and the spherical structure existed in deferens duc ... | 2011 | 22184027 |
| genetic identification of spirometra decipiens plerocercoids in terrestrial snakes from korea and china. | human sparganosis is a zoonotic disease caused by infection with larval forms (procercoid/plerocercoid) of spirometra spp. the purpose of this study was to identify spirometra spp. of infected snakes using a multiplex pcr assay and phylogenetic analysis of mitochondrial dna sequence data from the spargana of terrestrial snakes obtained from korea and china. a total of 283 snakes were obtained that included 4 species of colubridae comprising rhabdophis tigrinus tigrinus (n=150), dinodon rufozonat ... | 2016 | 27180576 |
| an exotic species is the favorite prey of a native enemy. | although native enemies in an exotic species' new range are considered to affect its ability to invade, few studies have evaluated predation pressures from native enemies on exotic species in their new range. the exotic prey naiveté hypothesis (epnh) states that exotic species may be at a disadvantage because of its naïveté towards native enemies and, therefore, may suffer higher predation pressures from the enemy than native prey species. corollaries of this hypothesis include the native enemy ... | 2011 | 21915306 |
| [a preliminary study on the identification of crude snake drugs by molecular genetic markers]. | dna was amplified from 11 samples of crude snake drugs by 2 random primers. "wushaoshe" (zaocys dhumnades) and its substitutes, elaphe taeniurus, e. rufodorsata, e. carinata and sinonatrix annularis, and "jinqian baihyashe" (bungarus multicinctus) and its adulterants, dinodon rufozonatum and sinonatrix annularis, can be distinguished by electrophoresis pattern of the amplified products. the results showed that the molecular genetic marker technique can be used as a new method for the identificat ... | 1997 | 11498877 |
| the occurrence of the strongylid nematodes kalicephalus brachycephalus, k. bungari and k. indicus in snake species from hunan province, china. | kalicephalus is a genus of strongylid nematodes infecting snakes and causing serious diseases and even death when it is complicated with secondary bacterial infections. the infection of snakes with kalicephalus has been reported in many countries in the world. however, little information is available on the prevalence of kalicephalus in snakes in china. in the present study, the prevalence of kalicephalus in snakes was investigated. the worms were examined, counted and identified to species acco ... | 2017 | 27188582 |
| reduced egg shell permeability affects embryonic development and hatchling traits in lycodon rufozonatum and pelodiscus sinensis. | the response of embryos to unpredictable hypoxia is critical for successful embryonic development, yet there remain significant gaps in our understanding of such responses in reptiles with different types of egg shell. we experimentally generated external regional hypoxia by sealing either the upper half or bottom half of the surface area of eggs in 2 species of reptiles (snake [lycodon rufozonatum] with parchment egg shell and chinese soft-shelled turtle [pelodiscus sinensis] with rigid egg she ... | 2018 | 28504478 |
| [dna barcoding and its utility in commonly-used medicinal snakes]. | identification accuracy of traditional chinese medicine is crucial for the traditional chinese medicine research, production and application. dna barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit i (coi), are more and more used for identification of traditional chinese medicine. using universal barcoding primers to sequence, we discussed the feasibility of dna barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 1 ... | 2015 | 26087547 |
