免疫应答对大鼠部分脑区中乙酰胆碱酯酶活性的影响

免疫应答对大鼠部分脑区中乙酰胆碱酯酶活性的影响彭聿平,邱一华,王健鹤（南通医学院生理学教研室南通２２６００１）测定脑内ＡＣｈＥ的活性可间接反映ＡＣｈ的含量,如果ＡＣｈＥ活性降低,表示脑内ＡＣｈ含量增高,反之亦然。国外文献报道,外周ＡＣｈ可增强Ｔ淋巴细...     

纹状体中亮—脑啡肽在针剌调节免疫功能中的作用

Zusanli points of rat were used to study the effect of acupuncture on the synthesis and release of endogenous leu-enkephalin (LEK) in modulating immune function as assayed by T lymphocyte proliferative response, i.e. the lymphocyte transformation test (LTT). The results are as follows: (1) LEK level in striatum was increased as LTT was enhanced by puncture. The latter effect could be inhibited by microinjection of naloxone into striatum. (2) Injection of LEK into striatum caused a significant enhancement of LTT, an effect being more powerful than did by electropuncture. (3) Following injection of LEK antiserum into striatum, electropuncture enhanced LTT was inhibited. The above results demonstrate that the LEK plays an important role in modulating cellular immune function during electropuncture, through its action in striatum either as a neurotransmitter or as a neuromodulator.     

孕婦尿對於引起雄蟾蜍排精的作用機制問題

早在1928年Aschheim和Zondek就證明在孕婦尿中含有類似腦下垂體前葉的促性腺激素,若將孕婦尿注射於未成熟的雌鼠,在96小時後,其卵巢即有血泡和黃體生成。1929年Friedman根據Aschheim-Zondek測驗之原理,利用兔子作實驗,在36
