台灣雞排酥炸粉檢出含毒澱粉 年吃20片可致不孕

為什麼吃含毒澱粉炸物十年會不孕？？？

 

毒澱粉事件持續延燒，彰化員林一家老牌粉行，被查出向協奇引進澱粉，再自行調製成含有超量順丁烯二酸的「獨家配方」酥炸粉，並供貨給下游的雞排攤、小吃攤和鹹酥雞店等，被查扣的毒澱粉高達17公噸。醫師表示，長期食用這些含有黑心毒澱粉的雞排炸物，可能導致不孕、腎病變，甚至誘發癌症。

Effects of malonic, maleic, citric and caffeic acids on the motility of human sperm and penetration of cervical mucus.

Brown-Woodman PD, Post EJ, Chow PY, White IG.

Abstract

 

 

The spermicidal effect of four organic acids (malonic, maleic, citric and caffeic acids) was evaluated by adding the acids to sperm, and by observing sperm survival and penetration following addition of these acids to human cervical mucus. Direct addition of 0.1% malonic, maleic and citric acid rendered the sperm immotile by a reduction of pH. In capillaries filled with cervical mucus, the incorporation of 0.01% maleic, malonic and citric acids was sufficient to reduce sperm penetration, and at 0.1%, penetration was completely abolished. Thus, malonic, and maleic and citric acids show promise as cervical or vaginal contraceptives. Caffeic acid was found to be unsuitable owing to its insolubility in aqueous media. Electron microscopy indicated that human sperm do not undergo the acrosome reaction while penetrating cervical mucus in vitro.

丙二酸，馬來酸，檸檬酸和咖啡酸對人類精子的活動力和穿透宮頸粘液的影響。

布朗伍德曼PD，郵政EJ，週PY，白IG。

抽象

四個有機酸（丙二酸，馬來酸，檸檬酸，馬來酸和咖啡酸）的殺精作用進行評價精子通過添加酸，通過觀察精子的生存和滲透後，這些酸對人類宮頸粘液。直接加入0.1％丙二酸，馬來酸和檸檬酸的渲染精子immotile的pH值減少。在毛細管中填充有宮頸粘液，將0.01％的馬來酸，丙二酸和檸檬酸是足以降低精子穿透，並在0.1％，滲透完全取消。因此，丙二酸，馬來酸和檸檬酸承諾宮頸或陰道避孕藥。咖啡酸被認為是不合適的，因為其在水介質中的不溶性。電鏡觀察表明不接受人類精子頂體反應，同時在體外穿透宮頸粘液。
