Re: [討論] 關於烏龍茶對血壓的影響。
我來試著翻一下,但我不是啥高手就是....
※ 引述《tttp86 (愛無法均分...)》之銘言:
: 也許大家平常會聽說,血壓高的患者應該少喝茶或是咖啡,不過這裡有篇有趣的論文,
: 有興趣的人不妨做做參考。
: 當然,舒張壓過高的人不論是什麼都還是少喝的好...
: Effects of oolong tea on renal sympathetic nerve activity and
: spontaneous hypertension in rats .
烏龍茶對於大鼠腎臟交感神經活性和自發性高血壓的效果。

: abstract
: =============================================================
: In a previous study, evidence was presented that oolong tea (OT)
: reduced abdominal fat accumulation in diet-induced obese mice.
在之前的研究中已經證實,有證據顯示烏龍茶對於大鼠因為飲食肥胖所引起的腹部
脂肪堆積具有消除效果。
: 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).
在本次實驗中,我們檢視了從十二指腸注入烏龍茶對urethane麻醉老鼠的交感活性
和心血管效果影響。而且發現,烏龍茶具有抑制腎臟交感神經活性和血壓的效果。
: 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,預先投以有H3 antagonist特性的thioperamide作預處理,或者是作
雙側subdiaphragmatic vagotomy以去除烏龍茶對RSNA及BP的效果。
: Furthermore, OT drinking for 14 weeks reduced BP elevation in
: spontaneously hypertensive rats.
另外,對於有自發性高血壓的大鼠,給牠喝14周烏龍茶,也有降血壓效果。
: These results thus suggest that OT may
: exert its hypotensive action through changes in autonomic
: neurotransmission via an afferent neural mechanism.
這結果顯示,烏龍茶的降血壓效果,是經由"傳入"的神經機制,來改變自律神經傳導。
: 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.
還有,我們發現,從十二指腸注入去咖啡因的烏龍茶對降低RSNA和BP的效果和
烏龍茶是一樣的,這顯示烏龍茶中一定含有咖啡因之外的RSNA和BP的神祕調控因子。

大意如上,請參考。
