Biologist Marshall Mackey (Marshall McCue ) from University of Arkansas (University of Arkansas ) undertook a study of the biological mechanism that enables some snakes to starve for up to two years.
For that, he spent 168 days observed 62 individuals of three snake species (distant relatives): Royal Python, white snake and Texas gramatnica.
Macku followed physiological, compositional and morphological changes of the snakes and found that snakes can reduce their metabolic rate by 72%! For this they use a special survival strategy in the absence of food, is not peculiar to any of vertebrates.
The rate at 72% is shocking, as “snakes and so consume little energy, and we still didn’t know how they manage to reduce energy consumption to such a low level”, ” says Marshall.
What’s even more amazing is the fact (also found by Makku) that snakes on loss from 9.3% to 24.4% of initial body weight continued to grow in length (especially increased size of the head – just like those snakes).
Day 168 to study rattlesnakes showed a record decline in the intensity of metabolism. He was only 28 per cent. Snakes reduced the metabolism to the bar in 55%. At the same time, the pythons, the maximum decrease in the intensity Continue reading
To date, the only method by which it was possible to save the life of a man bitten by a poisonous snake, was the timely introduction of a special serum. However, despite the fact that this drug has to be administered to the affected person as soon as possible, serum are available only in clinics. Now the situation has become much easier – American scientists have developed a spray that you can carry.
Created a new drug for the treatment of snake bites
We, the residents of the middle band, the bites of poisonous snakes is that familiar from the stories of Rudyard Kipling, whereas in some tropical countries the mortality rate from snake bites is only slightly behind deaths from AIDS.
According to the who, worldwide each year from the bites of poisonous snakes to the death of about 125 thousand people. Cause of death most of them (75%) is that the transportation of the victim to the nearest clinic, where available anti-typhoid serum, takes too much time.
Typically, serums are only supplied to medical facilities because of its cost. To have such medicines in their kits is allowed only to members of certain professions, such as Smelova, professional hunters, geologists.
Employees of the Department of anesthesiology of medical Continue reading
After hurricane Katrina await epidemics, invasions of snakes and alligators
Official representatives of the United States Federal government, which hastily sent medical equipment and professionals affected by the hurricane “Katrina” areas on the Atlantic coast of the country, warned that the disaster may entail very adverse consequences for the health of the population over a long period, writes The New York Times.
According to officials, they are particularly concerned about the likelihood of outbreaks due to contamination of drinking water by sewage, and because spoiled food and possible transfer of dangerous diseases of animals, especially insects, and the bites of poisonous snakes.
A lot of people died in the hurricane. Some were drowned. Two people died from carbon monoxide poisoning resulting from the use of gas generators in areas with poor ventilation. Nine persons poisoned with carbon monoxide, ended up in the hospital, said Federal officials at a press conference in Atlanta – the city in which is located the Center of control and prevention of diseases.
Yesterday rescuers have been searching the wounded and needy in the area where the hurricane, Continue reading
