background: snakebite is a serious public health problem in the world. the annual incidence of snakebites ranges from 4.5-9.1 in 100,000 population in iran. with regard to diversity of envenomation profiles in different geographical parts of iran, the aim of this study was to determine the demographical data, clinical and laboratory findings, and the outcome of the snakebite victims referred to...

Snake lungs show a remarkable diversity of organ asymmetries. The right lung is always fully developed, while the left lung is either absent, vestigial, or well-developed (but smaller than the right). A 'tracheal lung' is present in some taxa. These asymmetries are reflected in the pulmonary arteries. Lung asymmetry is known to appear at early stages of development in Thamnophis radix and Natri...

For animal populations in many parts of the world, direct (albeit often accidental) killing by humans may be a signi®cant source of mortality. Many snakes are killed by people (especially by automobiles) every year, but the determinants of a snake's vulnerability to anthropogenic mortality (and thus, patterns of mortality with respect to sex, age and season) are poorly known. We present data on...

Snake graphs are connected planar consisting of a finite sequence adjacent tiles (squares) T1,T2,…,Tn. In this case, for 1≤j≤n−1, two consecutive Tj and Tj+1 share exactly one edge, either the edge at east (west) (Tj+1) or north (south) (Tj+1). Finding number perfect matchings associated with given snake graph is most remarkable problems regarding these graphs. It worth noting that such allows ...

Diamond pythons (Morelia s. spilota) are large (to 3 m) snakes of temperate-zone coastal eastern Australia. Foraging behavior was studied by observation of telemetered snakes, and diets determined by dissection of museum specimens and collection of fecal samples from wild-caught snakes. Five adult snakes monitored in the field by radiotelemetry were found to be ambush foragers. In summer, telem...

Many snakes exhibit large increases in metabolic rate during digestion that place extensive demands on efficient oxygen transport. In the present study, we describe blood oxygen affinity following three weeks of fasting and 48 h after feeding in the Burmese python (Python molurus). We also report simultaneous measurements of arterial blood gases and haematological parameters. Arterial blood was...
