When ucashenie poisonous snakes, there are multiple, more or less homogeneous, the points lying in four longitudinal series, or a bunch in no particular order. Poisoning a poison snake, there are local and General reaction of the organism to received the poison. The nature and first and second different when ucashenie different snakes, and it is possible to establish General differences between ha and prednisoneandcatsyi lukavyj snakes poisonous snakes (pharmacologic class — Cobra).
