垂体内注射技术,是研究垂体内分泌机能的重要方法之一。文献报导的垂体内注射方法,多数是从动物颅骨顶部钻孔,借助立体定位仪定位,把一定长度的不锈钢细管,经大脑皮层垂直插入垂体内,然后固定,进行注射。这种埋藏导管法的缺点是麻烦、费时、动物损伤较大,而且需要特殊设备。本文介绍一种新的简易垂体内注射技术。 Pituitary injection technique is one of the important methods to study the function of pituitary endocrine. Pituitary injection methods reported in the literature, the majority of drilling from the skull top of the animal, with the help of stereotaxic positioning, a certain length of stainless steel thin tube, the vertical insertion of the cortex through the cerebral pituitary, and then fixed for injection. The drawbacks of this buried catheter approach are cumbersome, time-consuming, greater animal damage, and require special equipment. This article describes a new simple technique for pituitary injection.
