The ear veinsThe marginal ear veins are the only veins that are easily visible on pigs of any size. Usually there are three prominent veins. The lateral or central vein is usually the largest of these. The ear veins are branches of the caudal auricular vein and the superficial cervical vein. Their pattern, anastomoses and relative sizes vary from pig to pig.The pig in the picture weighs about 7 kg. An assistant holds......閱讀全文

柳葉刀:嚴重經期出血可咋辦?鎖孔子宮切除手術更有效
女性一個月總會有那么幾天不在狀態,尤其是在炎熱的天氣里,身上流著汗,下體流著血。不少女網友還自嘲是一匹汗血寶馬,不管喝多少熱水都緩解不了“血流成河”的悲劇。可怕的是,在英國有25%的女性受嚴重經期出血的影響,她們不得不接受手術治療。然而傳統的子宮切除手術雖然有效,但是它帶來的并發癥也不容小覷。
