在台灣，一名女人突然無緣無故的七孔流血暴斃，一夜之間，就奔赴黃泉！經過初步驗屍 . 斷定為因砒霜中毒而死亡。那砒霜從何而來？
In Taiwan, a woman suddenly died unexpectedly with signs of bleeding from her ears, nose, mounth & eyes. After a preliminary autopsy, it was diagnosed that it was due to arsenic poisoning . Where did the arsenic come from?
The police launched an in-depth and extensive investigation. A medical school professor was invited to solve the case.
教授仔細地察看了死者胃中取物，不到半個小時，暴斃之謎便 揭曉。教授 說：「死 者並非自殺，亦不是被殺，而是死於無知的『它殺』」！
The professor carefully looked at the contents from the deceased's stomach, in less than half an hour, the mystery was solved. The professor said: 'The deceased did not commit suicide and neither was she murdered, she died of accidental death due to ignorance!'
大家莫名其妙，何為『它殺』！？那砒霜又是從 哪里来？ 教授 說：「砒霜是在死者 腹 內 產生的。」死者生前每天會服食「維他命 C 」，這完全沒有問題！問題出在她 晚 餐吃了大量的蝦，吃蝦本身也是沒有問題的，所以她的家人吃了都沒有事，但死者卻同時服用了「維他命 C 」，問題就出在這裡 !
Everyone was puzzled, why accidental death? The arsenic is of the U.S. military for carrying rice seedlings H Gao. The professor said: 'The arsenic is produced in the stomach of the deceased.' The deceased used to take 'Vitamin C' everyday, which itself is not a problem. The problem was that she ate a large portion of shrimp/prawn during dinner. Eating shrimp/prawn is not the problem， that's why nothing happened to her family eventhough they took the same shrimp/prawn. However at the same time the deceased also took 'vitamin C', that is where the problem is!
Researchers at the University of Chicago in the United States found that soft-shell shrimp/prawn contains high concentration of - five potassium arsenic compounds.
這種物質食入體 內，本身對人體並無毒害作用！但是，在服用「維生素 C 」之後，由於化學作用，使原來無毒的－五鉀砷 ( 即砷酸酐，亦稱五氧化砷，其化學式為 As205) ，轉變為有毒的三鉀砷 ( 即亞砷酸 酐 ) ，又稱為三氧化二砷，其化學式為 (As203) ，這就 是人們俗稱的砒霜 !
Such fresh food by itself has no toxic effects on the human body! However after taking 'vitamin C', due to the chemical reaction, the original non-toxic - five potassium arsenic (As anhydride, also known as arsenic oxide, the chemical formula for As205) will be converted into three potassium toxic arsenic (ADB arsenic anhydride), also known as arsenic trioxide (chemical formula of As203) which is commonly known as arsenic to the public!
砒霜有原漿毒作用，能麻痺細血管，抑制 巰基梅的活性，並使肝臟脂變肝小葉中心壞死，心、肝、腎、腸充血，上皮細胞壞死，毛細血管擴張。故中其毒而死者，常是 七竅出血。 所以；為慎重起見，在服用「維生素 C 」期間，應當忌食蝦類。
Arsenic poisoning have magma role and can cause paralysis to the small blood vessels, suppresses "mercapto Jimei" effect, inhibits the activity of the liver and fat which leads to the necrosis of Hepatic Lobules Centre, at the same time incurring congestion of the heart, liver, kidney and intestine, epithelial cell necrosis and telangiectasia. Therefore, a person who dies of arsenic poisoning will shows signs of bleeding from the ears, nose, mouth & eyes.
Therefore, as a precautionary measure, DO NOT not take shrimp/prawn when taking 'vitamin C'.
