  • The present experiments were designed to investigate the effects of BangPoongSan on the cardiovascular system in the experimental Animals. And thus the change of blood pressure, auricular blood flow, artery contraction, death rate, platelet aggregation repression, plasma coagulation factor activity, plasma antithrombin activity, whole blood viscosity and plasma viscosity were studied. The result were summarized as the followings: 1. BangPoongSan dropped the blood pressure in the spontaneous hypertensive rat. 2. The drug increased the auricular blood flow in rabbit. 3. The drug relaxed the artery contraction by pretreated norepinephrine in white rat. 4. The drug inhibited the death rate of mouse which was led to thromboembolism by serotonin and collagen. 5. The drug inhibited the platelet aggregation in rat. 6. The drug prolonged the prothrombin time and activated partial thromboplastin time on the test of plasma coagulation factor activity in rat, but was not valuable. 7. The drug presented the antithrombin activity in rat. 8. The drug reduced the whole blood viscosity and plasma viscosity in rat, but the latter was not valuable. According to the results, Bangpoongsan increased the blood flow and dropped the blood pressure by dilatation of blood vessel smooth muscle. And the drug presented the antithrombin acivity, inhibited the platelet aggregation and reduced blood viscosity. Therefore these effects are assumed to improve the cardiovascular circulation disorder and prevent thrombosis.

  • Two polymeric prodrugs of PGE1 (prodrugs IVg and PNg) were newly synthesized. The drug conjugation proceeded in quantitative yield without decomposition of PGE1 to PGA1. With two types conjugates, PEG-PGE1 and PN-PGE1 with different spacer groups, we first discovered a possibility of slow release of PGE1 in blood circulatory system. PGE1 is conjugated with PEG and PN through the long alkylene spacers, and their availability as polymeric prodrugs is evaluated. Their drug-releasing behavior was examined both in phosphate buffer (pH=7.4) and rat plasma. Each prodrug was known to be highly stabile in the buffer solution. The drug-releasing rate became much faster in rat plasma than in the buffer solution due to the acceleration by the plasma enzymes. The drug-release was found to reach a plateau in rat plasma because the released PGE1 or its derivatives may be captured or decomposed by the plasma proteins. The slower drug-releasing rate of pro drug PNg in rat plasma is reasonably attributed to the molecular aggregation due to the hydrophobic bonding between the PGE1 moieties and spacers.

  • Objectives : CRATAEGII FRUCTUS(山査) is known as the substance which delays aging by the antioxidant effects. The purpose of this study is to investigate the effects of CRATAEGII FRUCTUS(山査) on antioxidant enzyme activities such as Thiobarbituric acid reactive substance(TBARS), Superoxide dismutase(SOD), Catalase(CAT), Glutathione peroxidase (GSH-px) in rat erythrocytes and blood plasma. Methods : Sprague-Dawley rats were divided into 3 groups, Normal group (supplied enough water and feeds only, Normal Group), D-galatose administered group(injected D-galatose 50mg/kg, 1time/day for 6 weeks, Control Group) and CRATAEGII FRUCTUS(山査) administered group (D-galactose 50mg/kg and CRATAEGII FRUCTUS(山査) extracts 85.0mg/200g 1time/day for 6 weeks, SS Group). Rats were sacrificed and TBARS, SOD, CAT, GSH-px, neutral fat and cholesterol were measured in rat erythrocytes and blood plasma. Results : There was no significant difference in the level of TBARS in the blood plasma between each experimental group. Red blood cell SOD activities were significantly different in each group. They were significantly decreased in the Control group compared to those of Normal and there was an increasing phenomenon in the SS group compared to the Control group. There was a significant difference in the activities of the red blood cell - glutathione peroxides in each group. There was a significant increase in the SS group compared to the Control group. Red blood cell catalase activities was no significant difference in each group. Plasma total lipid concentration was significantly different in each group. It was significantly increased in the Control group compared with the Normal group and it was decreasing in the SS group compared to the control group. Plasma triglyceride was not significantly different in each group. Plasma total cholesterol and Plasma HDL -cholesterol concentrations in the blood plasma were not significantly different in each group. Conclusions : According to the above results, it is considered that CRATAEGII FRUCTUS(山査) is effective in inhibiting lipid peroxides and increasing the activities of antioxidative(anti aging) enzyme in D-galactose induced aging rat.

  • The hemopoietic effects of deer blood (whole blood, blood cell, plasma, respectively) were examined using in vivo rat model. Experimental animals (Sprague-Dawley rat, male, 200 g) were divided into negative control group (injection of saline), positive control group (injection of Sipjeondaebotang) experimental groups (injection of whole blood, blood cell, plasma) and healthy control group. Cyclophosphamide(150mg/kg) was injected into experimental groups, negative and positive control group to induce bone marrow supression. After 8 days, freez dried deer blood (whole blood, blood cell, plasma respectively) and Sipjeondaebotang of 200 mg/kg in dose was administered orally into experimental groups and positive control group, once a day for 3 days (A group) and once a day for 12 days (B group) respectively. And then body weight and organ weight, biochemical profile (ALB, GOT, GPT, PRO, CRE), hematological values (WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT) and CBC differentiation (Neutro, Lymph, Mono, Reticulo) were carried out. Finally, platelets were specially increased in the plasma treated A group and reticulocytes were specially increased in the plasma treated B group.

  • Oriental pear was used as treatment of asthma, control of blood pressure tonic medicine diabetes in oriental medicine, Pear Pectin was effective on control of blood pressure in previous report. In this study, it was investigated that Woohwang with pear extractions effects on cardiovascular system as blood pressure and renin and Atrial natriuretic peptide(ANP) in plasma. The 2K1C hypertension model was prepared by constricting the left renal artery with a sliver dip. Animals were then divided into three groups, control, Woowhang:Pear Phenolic compound(1:1), Woowhang:Pear Phenolic compound(2:1),Woowhang:Pear Phenolic compound(1:2) were supplied with them. Direct-blood pressure was measured at femoral vein, Indirect-blood pressure was measured at rodent tail. The results are as follows. The blood pressure was more significantly decreased at 1:2(woohwang:pear phenolic compound)group than other groups. On 6,9,12,15days, the blood pressure was significantly decreased in 1:2(woohwang:pear phenolic compound)group. The plasma ANP was significantly increased in 1:2(woohwang:pear phenolic compound)group. It tenders to decrease in 1:2(woohwang:pear phenolic compound)group on plasma renin. Based on the above results it is assumed that oral administration of Woohwang with Pear Phenolic compound(1:2) can help the treatment of hypertension.

  • There are growing evidences suggesting a pivotal role of oxidative stress in the pathophysiology of preeclampsia. We investigated oxidative stress in the rat model of preeclampsia, and in clinical cases. Pregnant female rats were injected intraperitoneally with deoxycorticosterone acetate (DOCA) and given 0.9% saline as drinking water during their pregnancy. We assessed plasma $F_2-isoprostane(8-iso-PGF_{2{\alpha})$ and malondialdehyde (MDA) in a rat model, and the same markers in the plasma of maternal blood and fetal cord blood in pregnant women with preclampsia. Blood samples from the umbilical arteries and veins were collected separately. The concentrations of MDA were increased in the preeclampsia groups of animal and humans, compared with the control group; it was significantly increased in the umbilical artery and vein of the preeclampsia group. The concentrations of $F_2-isoprostane$ were elevated in the preeclampsia groups of animal and humans, compared with the control group, and the increase in $F_2-isoprostane$ concentration was prominent in the umbilical vein than umbilical artery of the preeclampsia group. Therefore, it appears that the placenta has an important role in the pathophysiology of preeclampsia, and the $F_2-isoprostane$ of the umbilical vein may serve as a relatively reliable marker for ischemic/hypoxic injury to the fetus during the perinatal period.
