基于Runtime的iOS编程研究与实现

在iOS开发过程中,因为系统自带方法对应的功能不足,使部分业务需求不能有效地实现.为此,首先对Runtime库的主要API接口用途进行了研究,找到可利用的接口;然后对Runtime消息转发机制进行研究,证明函数调用的实质就是消息的传递;最后通过实际案例,证明了应用Runtime可以解决系统方法不足的问题.结果 表明,通...     

Influence of pinealectomy on corticotropin (ACTH)

Sensory deprivation produced by removing the eyes and olfactory bulbs in male rats allowed pinealectomy to markedly augment the post-adrenalectomy elevation of ACTH levels. Pineal removal or sensory deprivation separately did not have this effect. Thus, intact sensory input and an intact pineal gland are independently capable of restricting the post-adrenalectomy rise in ACTH levels.     

Inhibition of human chlorionic gonadotrophin-induced ovarian and uterine growth in the mouse by synthetic arginine vasotocin-1.

21-day-old Swiss-Webster female mice were injected with 1 IU HCG at 09.00 h. Injection of freshly prepared arginine vasotocin (2 mug/0.1 ml/injection) every 12 h inhibited the HCG-induced hypertrophy of the ovaries at 36, 48, 60 and 72 hr after HCG-treatment while the uterine weight was depressed at 60 and 72 h.     

Inhibin beta in central neural pathways involved in the control of oxytocin secretion

Inhibin (I) a gonadal hormone glycoprotein which suppresses follicle-stimulating hormone (FSH) secretion from the anterior pituitary, is a heterodimer consisting of an alpha subunit and one of two distinct beta subunits. S1 nuclease analysis has revealed that RNAs encoding all three subunits (alpha, beta A and beta B) are expressed in rat brain. We report here on the localization, and a potential function, of inhibin beta in the rat brain. A cell group centred in the nucleus of the solitary tract (NTS), a major recipient of visceral sensory information, was stained immunohistochemically with antisera against synthetic fragments of I beta, but not I alpha. The distribution of I beta-stained fibres is consistent with known NTS projections, and includes a prominent projection to oxytocinergic aspects of the magnocellular neurosecretory system.
