Skin Lesions caused by poisonous snakes

From venomous snakes the most dangerous bites of Cobra, spectacled serpents, vipers, some sea snakes. Their bites (usually hands, feet) are accompanied by local pain, progressive edema of the affected limb, passing sometimes on the trunk. At the bite location revealed two reddish dotted wound; soon around them appear petechiae or hemorrhages, which can be detected also on mucous membranes.

There is cyanosis and rapid swelling of limbs, increasing the General toxic reaction. In some cases, develop kollaptoidnoe state. Bites of snakes up to 15% of bitten die from heart failure, paralysis of the respiratory center 3-4 days after the bite.

Treatment: rapid removal (suction) of the poison from the wounds (effectively in half an hour); immobilization of extremities; the introduction of anti-typhoid serum in the interscapular region (20-100 ml); epinephrine, caffeine, kordiamin, ephedrine; novocaine blockade around the bite; systemic corticosteroids in medium doses.

“Types of snakes”

Found a gene that determines, will become a gamete sperm or egg

Japanese genetics found in the DNA of fish unusual gene that determines it, will the sex cell sperm or egg, and changed his work so that in the ovaries of female fish began to form spermatozoa and in the testes of males of the egg, according to a paper published in the journal Science .

“We knew that gametes can turn into sperm and ovum, but no one has suggested that these cells in the vertebrate animals have a special gene”switch” that determines their fate – to become a sperm or egg. Our results indicate that the cell is able to go all the way. This is a very important and unexpected discovery” – quoted by RIA “Novosti” scientist Minoru Tanaka from the Institute of General biology of Japan in the city of Okazaki.

Tanaka and his colleagues made this unusual discovery, watching the development of germ cells in testes and ovaries rice fish-oriii (Oryzias latipes). During maturation of sperm and egg cells, researchers monitored changes in the level of activity of different genes, trying to find the differences between future male and female reproductive cells.

The attention of scientists was attracted to gene foxl3 – “archival copy” of the gene foxl2, which is responsible for growth of eggs and maintaining Continue reading

Royal Python

Problems with young.Part 1.

Infant vardousia or hardened yolks, hard belly, mass in Ball python hatchlings.

Newborn Regius, born in razvodnyh world level (captive breed, next, CB) or on a snake farm in the wilds of the jungle (farm breed, then FB), sometimes present surprises. In the last third of the body they have formed a small swelling. If you palpate the area, you’ll find some solid foreign body. It can be of different sizes and in some cases take up half the volume of the digestive tract of the snake. It’s not stool, as some might think, this so-called hardened yolk (hard yolk). Foreign colleagues use the term “hard belly” to refer to this problem, in a literal translation on Russian it sounds like vardousia.

The good news is tendopathies suffer only newborn Regiony. Suffer the vast majority of cases, not for long. Somehow solid the yolk mass is blocking the intestine, which threatens the life of a newborn Python. If the mass, which is visually similar to the oblong lump of matter, not removed in time, the snake will die of starvation and dehydration. If you delete, the chances of survival of the young of Ragusa will be slightly higher, but according to statistics, only 10-20% of the pups live longer than two months after the procedure.

Removing Python from the tumor, by contacting the veterinarian or yourself. In any case, you should be prepared for the fact that a dense mass inside the belly of a snake Continue reading
