Jellyfish venom can cause different degrees of harm to human body. For example, sea wasp jellyfish can secrete venom similar to cobra, which is the most harmful to human beings and can kill people within 5 minutes after being stung. Jellyfish contain "hypnotic toxin", which is composed of peptide, protein and nitrogen. After stinging the human body, the patient can only get rid of the pain for many days. There are common jellyfish floating in the Yellow Sea off the coast of China, which can secrete peptide poison. Jellyfish toxins are stored and distributed in gill boxes. The 65,438+0g card box contains 55 million single-needle card boxes. Generally, after fishing, its toxicity can disappear quickly after processing. Animal experiments have proved that jellyfish toxin is harmful to the emotional conduction system of mammals and the heart of crustaceans, and can cause contraction of small intestinal smooth muscle in rats. It is found that jellyfish toxin is tetramine complex, 5- hydroxytryptamine and polypeptide, which has strong histamine reaction. Its effects of dilating blood vessels and enhancing capillary permeability are 10 and 15 times that of 5- hydroxytryptamine respectively. It can also cause smooth muscle contraction or allergic reaction, leading to severe pulmonary edema and anaphylactic shock.
