Recently, I always saw people say how weak the toxicity of bamboo leaf green is, it is simply the existence of the bottom of the poisonous snake, it is not worthy of the title of poisonous snake at all, and it is also claimed that he has been bitten many times without a little poisoning reaction, which has caused a large number of people to question bamboo leaf green, so is bamboo leaf green really as poisonous as people say? First of all, let's re-understand the bamboo leaf green, bamboo leaf green is the most common kind of highly venomous snake in China, it is viper family, pit viper subfamily, bamboo leaf green genus, bamboo leaf green genus can be more than one kind of snake, it has many subspecies, like Fujian bamboo leaf green, white lip bamboo leaf green, Yunnan bamboo leaf green, island bamboo leaf green, Taiwan bamboo leaf green and so on many varieties, mainly distributed in most provinces in China and India, Vietnam, Thailand and other Southeast Asian countries.
Mention of bamboo leaf green to most people to leave the impression is emerald green, slow movement, weak toxicity and other obvious characteristics, in fact, different bamboo leaf green body size, habits, toxicity and color also have their own advantages, not all green, there are light yellow, dark green, cyan and sky blue, people say that the bite can not be killed usually refers to Fujian bamboo leaf green. Fujian bamboo leaf green is the most widely distributed bamboo leaf green snake in China, which can be seen in all areas south of Henan, and it is also the most toxic of all bamboo leaf green. Its toxicity test is: subcutaneous injection ld50 = 3.3mg / Kg, the toxicity alone is not weak, it is about 3 times that of the five-step snake, the infusion is infused in the amount of venom, the detoxification amount of Fujian bamboo leaf green is low and pitiful, only about 5 mg, less than one-fifth of the five-step snake.
The venom type of Fujian bamboo leaf green is blood circulation toxin, the bite pain is unbearable, the wound is like a fire, in addition to the swelling and bleeding is not serious, the damage to human body function is also very small, so it makes people think that the bamboo leaf green bites the undead, is the existence of the bottom of the poisonous snake. However, the distribution range of Fujian bamboo leaf green is very wide, the number is large, is one of the most injurious poisonous snakes in China, every year it bites as many as a thousand patients, even if only 3% of the fatality rate, can also poison 30 people, according to the degree of threat to humans, even more than the king cobra. And we said that Fujian bamboo leaf green is only one of the weakest of many varieties, does not represent the bamboo leaf green family, China's bamboo leaf green is the most toxic is the white lip bamboo leaf green, because it has a white line under the mouth, so it got its name.
White-lipped bamboo leaf green and Fujian bamboo leaf green distribution range is the same, but the number is relatively small, the habits are not the same, it likes to haunt the mountains, plains and other places, inhabit the shrub and wood areas, far from the range of human activities, so the frequency of injury is not high, the cumulative number is only a few hundred. However, the toxicity of white-lipped bamboo leaf green is super strong, it can be said that the toxicity performance alone exceeds that of all pit vipers in China, and its toxicity test is intravenous injection of ld50 = 0.5mg/Kg, the average detoxification amount is more than 20 mg, and the bite symptoms are also completely different from those of Fujian bamboo leaf green. According to one injured person, after he was bitten by the white-lipped bamboo leaf green, the wound began to appear swollen, blackened, hardened and other symptoms in just over 10 seconds, and the poison hair was very rapid.
After that, he simply rinsed with water, the pain was very obvious when squeezing the wound, and accompanied by certain bleeding symptoms, about half an hour or so, his entire palm began to appear edema, the wound was largely blackened and bleeding, and the family was still thinking that the ordinary bamboo leaf green bite could be so serious? Even if they suspected that Zhu Yeqing was injured, they quickly sent him to the hospital. After the doctor's examination confirmed that it was a white-lipped bamboo leaf green bite, and injected him with an anti-pit viper serum and 6 stitches of skin lesion repair drugs, the arm injury was relieved and began to gradually reduce, but the pain has never subsided. After 20 hours after being bitten, the wound pain suddenly intensified, as if burning a wound with a red-hot soldering iron, and the abdominal muscles, neck muscles, and arm muscles were accompanied by soreness, and the symptoms lasted for more than ten hours before they finally subsided, which also made the injured person sleepless for several days after being bitten.
After a week of recuperation in the hospital, the injury was completely controlled, the doctor said that it was fortunate to be sent in time, otherwise he might not be able to keep his finger bitten, and now that he thinks about it, he is afraid and knows the horror of Zhu Yeqing. In the case of white-lipped bamboo leaf green injury, more than 60% of patients' wounds will have bleeding, severe swelling and a certain degree of ulceration, necrosis, severe can lead to multi-organ bleeding failure, acute kidney failure, etc., the fatality rate can reach more than 19%, to know that China's most poisonous silver ring snake fatality rate is only 25% or so, which shows that white-lipped bamboo leaf green can not only be fatal, the disability rate is also very high. But don't worry, bamboo leaf green looks the same, or very recognizable, the neck is thinner, the head is wide and triangular, the eyes are red and yellow, the tail end has a touch of red, the body size is usually not more than one meter, the arboreal is very strong, like to be in the ground at night with phototropism.
Therefore, when encountering bamboo leaf green, you can't let down your vigilance, whether it is white-lipped bamboo leaf green or not, it may be fatal, some people may ask, then who is stronger than the five-step snake? Bamboo leaf green and five-step snake still has a big gap, five-step snake is notorious rotten meat king, the patient who was bitten by it can be said to be either dead or disabled, the blood circulation toxin of the five-step snake contains a strong hemolytic ability, the damage to human body function is particularly huge, not only can cause serious bleeding, but also let the injured skin ulcerate, swelling, necrosis, necrosis ability has not yet been able to match which snake. However, the test toxicity of the five-step snake to mice is not prominent, only the subcutaneous injection ld50 = 8.9mg / Kg, the toxicity alone is still better than the bamboo leaf green, but it is better than the amount of detoxification, the average can reach more than 200 mg, the degree of damage to human body function is very terrible.
It can be seen that toxicity is not the only criterion for judging the strength of venomous snakes, and has a lot to do with quantity, detoxification, and habits. Just like the king cobra although powerful, but the number is rare, there are few cases of injury, Although The Fujian Bamboo Leaf Qing is weak, but it is better than the number of people, the number of people bitten by the Fujian Bamboo Leaf Green in China is as high as tens of thousands, even more than the silver ring snake, and the frequency of injury is one of the best in The country, so we can not underestimate it. Therefore, when encountering bamboo leaf green, no matter which one is not easy to approach, it is not as weak as people think, and it is completely worthy of the top ten poisonous snakes in China.
