A couple suffered from poisoning after eating the euramis at the food stalls. They were turned into dangers by medical treatment. According to reports, the couple was diagnosed with "Sycatoxin poisoning." Xueka poisoning has also been translated as poisoning of fish poisoning in the West, which is a low mortality poisoning caused by poisonous fish eating around coral reefs in the tropical and subtropical seas and near shores.
The most concentrated poisoning of poisoned fishes in the West has occurred in the Caribbean Sea and the Indo-Pacific region. There are also quite a few cases in Japan. Recently, individual cases have also been reported in Hong Kong and Guangzhou.
Everyone is familiar with poisoning of puffer fish, but unlike the poisoning of fish in the West, poisoned fish in the West are generally non-toxic and are edible fish. The reported species of poisonous fish include 11 orders, 55 families and 426 species of bony fishes. There are dozens of species such as sea bream, grouper, and thrush in the South China Sea. Whether or not the fish is toxic is not a rule. Even in the same sea area, fish on the same reef are sometimes toxic but sometimes non-toxic. Fish are poisonous, but fish are small and non-toxic. The mortality rate of poisoning fish poisoning in western China is extremely low, but the disease course often lasts for several weeks to several months.
There are many species of toxic fish toxins, and some of the major toxic components have been isolated and purified. They are structural molecules of polyethers. They have many polar and non-polar groups, and have hydrophilic and lipophilic nature. Strong, but the content of fish is minimal, and it is difficult to achieve lethal doses. Since the toxoid fish toxin is also found in toxic algae, and the individual large fish content is high, some people think that the toxin is accumulated in the body after the fish eats a lot of toxic algae.
Sitotoxic fish toxins are mostly sodium channel activators, and their properties are opposite to those of puffer fish. Some of the western poisonous fish toxins are calcium channel agonists. The effect of these toxins on ion transport is the cause of poisoning.
The clinical manifestations of poisoning in fish poisoning in the West include gastrointestinal, cardiovascular, and nervous systems. The incubation period of poisoning is an average of 6 hours. The clinical manifestations usually start with gastrointestinal symptoms, metallic taste, nausea, vomiting, watery diarrhea and abdominal cramps, or with chills and fever. In some patients, the onset of symptoms starts from nervous system symptoms and muscle around the mouth Numbness, followed by leg muscle pain, numbness, gait instability, abnormal feelings, especially for the temperature feel upside down, feel cold when in contact with cold, feel cold when touched hot. In severe cases, hypotension and bradycardia may occur. Symptoms last for several weeks and the symptoms of recurrent poisoning are even more severe.
Patients with the above symptoms and those who have a history of feeding large tropical reef fish should consider the possibility of poisoning by fish poisoning in the West. Due to the absence of specific antipsychotics, symptomatic treatment and supportive therapy should be used. Intravenous infusion of mannitol has been reported to significantly ease the condition. The recommended dose is 1 g/kg, and the total amount of 20% solution does not exceed 250 ml. But also pay attention to the addition of glucose saline to relieve dehydration. Anticholinergic drugs and adrenal cortical hormones are not effective and should be avoided as much as possible to prevent interference with other physiological functions. When the acute phase is over, high protein, high electrolytes, and multivitamins should be supplemented, but fish, shellfish, and alcohol should not be eaten to prevent recurrence and aggravation of symptoms of fish poisoning caused by western poisoning.
Deep-water fish are clean, rich sources of protein, and are useful food because they are far from human activities in the sea and are not contaminated by human activities. Since toxins in the fish are only 0.000001 to 0.00020 micrograms per kilogram of fish, even if they eat 1 kilogram of fish, the toxin content is far below the minimum poisoning volume of 0.1 micrograms, so it is generally safe. At present, no more than 10 cases of poisoning have been reported in the Guangzhou area. They are all lighter recoverable cases. Although no undiagnosed cases have been included, the incidence is believed to not exceed that of freshwater fish. The incidence of bleeding caused by bone puncture injury in the esophagus.
However, the deep-water fish have very different levels of toxins, whether they contain a large amount of toxins and they cannot be identified according to their appearance. They cannot be guaranteed by cooking, freezing, drying, smoking and salting. In tropical fish, two things should be kept in mind: 1. Do not eat viscera with high levels of toxins; 2. Do not eat in large quantities, and fish of large size should be careful. Miami residents in the United States gave fish guts to cats or dogs before eating. They were given no food after 12 hours. They are clever preventative measures.
total alkalinity: prevent fluctuation in pH levels
Free Chlorine: Chlorine may be present in tap water. It is harmful to fish, damaging their gills and skin, and must not be introduced to the aquarium
pH: pH value between 6.5 and 8.5 will be tolerated by most freshwater fish species
Bromine: Keep your bromine levels on point and effective
Total hardness: prevent corrosion and scaling in your pool or spa
tatal chlorine: know exactly when to shock your water
