国大一名Dr.呼吁O+血型的献血者！！！！Dear Colleagues, You might recall that some time ago I appealed to you for O+ platelets donation for a son, named Cheng Tian, of a friend and colleague of mine, Dr Lou Jiann Hua of Math Dept. Cheng Tian's auto-immune problem resulting in some type of blood disorder continues to trouble him and is life-threatening. Going in and out of NUH almost becomes a routine. In the last couple of days, he bled for about 13 hours from about 8PM (13 March) till about 9AM (14 March) while staying in NUH. At some point, Mrs Lou thought to herself that she had to prepare for the worse... Therefore I would like to appeal again for potential O+ platelets donation. Thanks for your kind support and concern. Warm Regards, Brian (on behalf of Dr & Mrs Lou) ========================info about blood donation provided by Dr. Lou Jiann hua=========================== O+ platelet donors are needed.

天哪, 楼剑华是个好老师啊, 怎么命这么苦!!!!当年众多教过我的老师,他是个人魅力最高的一位,每次路过Math那里我都会想起他来... 谁是O+的血型啊, 帮帮他吧!

好像是她的学生吧....

区别是O+是O的一个子集。 血型的区分主要是通过血细胞表面的糖蛋白或蛋白来分类。常用的是ABO，主要是对于一种蛋白的不同的糖基化。而+/-指的是一种比较特殊的蛋白RH的存在与不存在。两者是处于并列关系。 所以经常会有B-或者O+的说法，B-在亚洲人种中是比较罕见的一种血型。
