我将肉毒杆菌素和盐水混合，抽到两支注射器里，每支注射器的末端都带有一个微小的、黄色的针头，然后把它注射到整个腋窝下的多个点。

I mix the Botox with saline, drawing it up into two syringes, each tipped with a tiny, yellow needle, then inject it at multiple points across the armpit.

方法：在鼠模型中运用27G和33G大小的针头、羊模型中运用27G针头假注射磷酸盐缓冲盐水到椎间盘中，之后通过测量力学进行评价。

Methods. Mechanics were measured after sham phosphate buffered saline injection with a 27 G or 33 G needle in the rat and with a 27 G needle in the sheep.
