    Animal training

    因为毕业课题要做动物实验,所以报名参加了animal training,周四一上午的boring lect on regulations,周五一整天的hands-on,上午四小时rat session,下午四小时aseptic surgery,明天上午还有四小时的mice session。说起来还蛮有意思的。想必国内学生物的同学肯定早就解剖过小白鼠,我却还是第一次见实验用的老鼠。我们学了如何抓起它们,辨别公母,打麻醉,从不同的位置注射,取血。看那些小白鼠还真挺可爱的,但是为什么不觉得它们很可怜呢?如果是兔子可能还会博取我更多的同情心。那天老鼠们状态都不太好,一抓起来就吱吱乱叫,连老师都不太敢硬抓它们,怕被咬到,我们也只敢抓起尾巴,把它放到胳膊上呆一会,就赶紧放回笼子里。它们的指甲还真长,隔着lab coat也能感觉到。麻醉有两种方式,注射和气体。之后我们在被麻醉的老鼠身上分别试了皮下,肌肉,腹部和尾部注射;从尾部,脸颊和心脏取血。最后可怜的老鼠就被放到通二氧化碳的盒子里安乐死了。下午aseptic surgery用的就是上午我们用过的安乐死后的老鼠,腹部和背部的毛都被剔去了。在看完老师的demo后,我们就开始对自己面前的小白鼠动刀了,先把腹部的皮割开一个大口,再把下面一层的肌肉割开,于是便露出了里面的内脏,能看到黄黄的肠子和深红色的肝,不过我们不解剖,只是练习缝合,用所教的三种缝法分别缝合了肌肉,表皮和背上的皮肤。感觉就跟缝衣服一样,还蛮好玩的,缝完后还挺有成就感的。割的时候小心翼翼的,生怕碰到血管,结果很奇怪,都不会流血的。明天还有个头比较小的mice session,期待中。。。
