Condition. Regarding this, the psychology research gives the explanation is: Happy can cause the cerebral cortex to appear a new excited stove, according to negative induction rule, when tense mental labor causes the cerebral cortex excited region obtained the rest, can play the elimination to be weary,adjustment nerve activity good role.

对此，心理学研究给予的解释是：欢愉会使大脑皮层出现一个新的兴奋灶，根据负诱导规律，紧张脑力劳动时所引起的皮层兴奋区域得到了休息，就会起到消除疲劳，调节神经活动的良好作用。

The results obtained are as follows:(1) injection of 50, 100, and 200 nmol/kg adenosine into the renal artery increased the renal afferent nerve activity in a dose-dependent manner with unchanged arterial pressure;(2) pretreatment with 8-cyclopenthl -1,3-dipropylxanthine (DPCPX, 160 nmol/kg), an adenosine A1 receptor antagonist, partly abolished the effect of adenosine; and (3) pretreatment with a nitric oxide synthase inhibitor N w-nitro- L -arginine methylester (L -NAME, 0.1 mmol/kg) significantly enhanced the ARNA response to adenosine.

结果表明：(1)肾动脉内注射50， 100和200 nmol/kg腺苷可呈剂量依赖性地兴奋肾神经传入纤维的活动，而动脉血压不变。(2)肾动脉内预先应用选择性腺苷A1受体阻断剂DPCPX (160 nmol/kg)，可部分阻断腺苷对肾神经传入纤维的兴奋作用。(3)静脉应用一氧化氮合酶抑制剂 L -NAME(0.1 mmol/kg)预处理，延长并增强了肾神经传入纤维对腺苷的反应。
