我来试着翻一下,但我不是啥高手就是....
※ 引述《tttp86 (爱无法均分...)》之铭言:
: 也许大家平常会听说,血压高的患者应该少喝茶或是咖啡,不过这里有篇有趣的论文,
: 有兴趣的人不妨做做参考。
: 当然,舒张压过高的人不论是什麽都还是少喝的好...
: Effects of oolong tea on renal sympathetic nerve activity and
: spontaneous hypertension in rats .
乌龙茶对於大鼠肾脏交感神经活性和自发性高血压的效果。

: abstract
: =============================================================
: In a previous study, evidence was presented that oolong tea (OT)
: reduced abdominal fat accumulation in diet-induced obese mice.
在之前的研究中已经证实,有证据显示乌龙茶对於大鼠因为饮食肥胖所引起的腹部
脂肪堆积具有消除效果。
: In the study presented here, we examined the sympathetic and
: cardiovascular effects of intraduodenal injection of OT in
: urethane-anesthetized rats and found that it suppressed renal
: sympathetic nerve activity (RSNA) and blood pressure (BP).
在本次实验中,我们检视了从十二指肠注入乌龙茶对urethane麻醉老鼠的交感活性
和心血管效果影响。而且发现,乌龙茶具有抑制肾脏交感神经活性和血压的效果。
: In addition, pretreatment with the histaminergic H3-receptor
: antagonist thioperamide or bilateral subdiaphragmatic vagotomy
: eliminated the effects of OT on RSNA and BP.
除此之外,预先投以有H3 antagonist特性的thioperamide作预处理,或者是作
双侧subdiaphragmatic vagotomy以去除乌龙茶对RSNA及BP的效果。
: Furthermore, OT drinking for 14 weeks reduced BP elevation in
: spontaneously hypertensive rats.
另外,对於有自发性高血压的大鼠,给牠喝14周乌龙茶,也有降血压效果。
: These results thus suggest that OT may
: exert its hypotensive action through changes in autonomic
: neurotransmission via an afferent neural mechanism.
这结果显示,乌龙茶的降血压效果,是经由"传入"的神经机制,来改变自律神经传导。
: Moreover, we found that intraduodenal injection of decaffeinated OT
: lowered RSNA and BP as well as OT, indicating that substances
: other than caffeine contained in OT may function as effective
: modulators of RSNA and BP.
还有,我们发现,从十二指肠注入去咖啡因的乌龙茶对降低RSNA和BP的效果和
乌龙茶是一样的,这显示乌龙茶中一定含有咖啡因之外的RSNA和BP的神秘调控因子。

大意如上,请参考。
