Protective effects of Ginkgo biloba extract (GBE) on ischemia in rat and mice brain were studided. The ischemia model in brains was prepared by occlusion of bilateral carotid arteries and vertebra arteries in rat. The results demonstrated that GBE had no effect on electroencephalogram (EEG) of 5 min of ischemia, but it promoted the recovery of EEG during reperfusion. When it was reperfushed for 10 min,amplitude of EEG in the control group only recovered from 17. 2% after ischemia to 46. 6% of normal level. While 0. 2g/kg GBE has a recovery of 93% from normal level. At 4. 0g/kg GBE the life-span of mice with bilateral ligated carotid arteries was significantly lengthened. The above results proved that GBE has some protective effect on anoxia caused by acute ischemia in rat and mouse brain.

Objective To explore the relationship between 24 h ambulatory blood pressure monitoring (24h-ABPM) parameters, circadian rhythm and urinary albumin to creatinine ratio (UACR), urineβ2 microglobulin (β2-MG) in elderly patients with hypertension. Methods One hundred and forty-eight patients with essential hypertension (≥60 years old) were included in this study. 24h-ABPM was performed, and nocturnal blood pressure decline rate (BPR) was calculated. The patients were divided into two groups according the BPR:dipper group with 40 cases and non-dipper group with 108 cases. The levels of 24h-ABPM parameters, UACR and β2-MG were compared between two groups, and the relationship between UACR and 24h-ABPM parameters were analyzed. Results The levels of 24hSBP, dSBP and 24hDBP in two groups had no significant differences (P>0.05). Compared with those in dipper group, the levels of nSBP, nDBP in non-dipper group were significantly increased, and the level of dDBP was significantly decreased, P<0.01 or <0.05. The level of 24hPP in non-dipper group was significantly higher than that in dipper group (P<0.01). The levels of UACR andβ2-MG in non-dipper group were significantly higher than those in dipper group (P<0.05). The levels of BUN and SCr in two groups had no significant differences (P>0.05). The result of Sspearman analysis showed that UACR had significant correlation with 24hDBP, nDBP, 24hSBP, nSBP and 24hPP (P<0.05 or<0.01). The result of multivariate linear regression analysis showed that UACR was independently correlated with nSBP (P<0.05). Conclusions The abnormal circadian rhythm in elderly hypertensive patients is closely related to early renal damage.

AIM To set up the model of stom- effects of its treatment drugs. METHODS To ap-ach smooth muscle cells contraction and assess the ply the culture of isolated stomach fundus smooth muscle cells in rats in vitro and to obtain the mixture of stomach smooth muscle cells. The cells were examined with the Trypan blue dilution technology under microscope and the length of cells and the contraction rate of muscle cells were adopted to the evaluation index of effects. The change of cells in different time was observed and calculating the survival rate and time of cells. The selected neuro-medium and its antagonist, such as acetyl-choline chloride (ACh) and atropine, 5-HT and domperidone(Domp) , histamine( His) and diphen-hydramine(Diph) were added to the mixture cells so as to provoke irritant reaction observe the effects of drugs. RESULTS Obtaining cells in stomach fundus smooth muscle was more than 1 X 106 in each rat by this way, and the survival rate and time of cells was 95% and 2. 5 h. The contraction of cells was observed after adding ACh 5-HT or His ,and the effects of these agents were antag- onized by antagonist atropine, Domp and Diph respectively. The effects of maximum contraction of ACh in concentration 1?10-8 mol ? L-1 was 38%, and in 5-HT may exist two receptors, and the maximum rate was 20. 7% and 10. 5% respectively. The effective dose of contraction was 1 X 10-13 -1?10-10 mol ? L-1 induced by His, the contraction effects was significantly weakened in high of 1 ?10-10 mol ? L-1 and antagonized by Diph. CONCLUSION The smooth muscle cells by digesting stomach fundus smooth muscle of rats would be more than 95% survivors and survival time was more than 2. 5 h. ACh,5-HT and His could induce the contraction of smooth muscle cells, and the effects of contraction were antagonized by atropine, Domp and Diph respectively.
