The purpose of this research was to investigate effects of Astragali Radix(AR) and Armeniacae Semen(AS) on T-lymphocytes and peritoneal macrophages in mice. The proliferation of thymocytes and splenocytes were teated using macroplate-reader. The apoptosis and sub-population of T-lymphocytes were tested using a flow cytometer. Nitric oxide production was tested using a Griess reagents. The result were obtained as follow; 1. AR increased the proliferation of thymocytes and splenocytes. 2. AS decreased the proliferation of thymocytes and splenocytes. 3. AR and AS decreased No production fron peritoneal macrophages 4. AR and AS were accelerate T-lymphocytes apoptosis. 5. AR and AS increased $T_C$ cells population, but decreased $T_H$ cells population of T-lymphocyte.

Effects of Astragali Radix Water Extract (ARWE) on the blood pressure were investigated in the whole rabbit and the spinalized rabbit. ARWE, when administered into the ear-vein or lateral ventricle, produced a fall in the blood pressure in the whole rabbit, but intravenous ARWE in the spinalized rabbit did not elicite the hypotensive action. Pretreatments with chlorisondamine, guanethidine, phentolamine and cyproheptadine in the whole rabbit weakened the depressor action of ARWE. The hypotensive action of the whole rabbit to ARWE was not influenced by the pretreatment of the animals with diphennylhydramine, propranolol, and vagotomization, whereas inhibited by atropine. ARWE did not affect the pressor response by angiotensin. However, it enhanced the hypertensive action by norepineprine and reduced the elevation in the blood pressure by carotid occlusion in the whole rabbit. These experimental observations suggest that ARWE may cause the depressor response via mechanisms of the central sympathetic blocking action, cholinergic action by peripheral origin and serotonin-like action.

The purpose of this study was to investigate the effects of Polygonati Rhizoma on the diet-induced hyperlipidemia in rats. Rats were divided into 4 groups, normal group(supplied enough water and feeds only), high fat diet administered group(supplied high fat diet for 4 weeks, Control group) and Astragali Radix administered group(supplied high fat diet and Astragali Radix lyophilization extract for 4 weeks, 397.3 mg/kg(rat) in sample A, 662.5mg/kg(rat) in sample B). Body weight, liver weight and serum lipid levels were evaluated. The water extract of Polygonati Rhizoma decreased body weight, liver weight, total cholesterol, LDL-cholesterol, triglyceride and phospolipid in high fat diet induced hyperlipidemia in rats, and increased HDL-cholesterol.

This study was performed to investigate genes which are differently expressed in human blood by administrating of OLT-2. OLT-2 was medical precipitation composed of three medicinal herbs, Ginseng Radix, Astragali Radix, Glycyrrhizae Radix, and anti-leukemia effect of it was evaluated from Byung Hun Jeon of Wonkwang University this study was approved by Institutional Review Board of Korea Institute of Oriental Medicine (Taejeon, Korea) and four male subjects participated in this study. Gene expressions were evaluated by cDNA chip, in which 24,000 genes were spotted. Hierarchical cluster and biological process against the genes, which expression changes were more than 1.6 fold, were constructed by cluster 3.0 providing Stanford University and EASE(http://apps1 .maid.nih.gov/DAVID). Five groups were clustered according to their expression patterns. Group A contained gene decreased by OLT-2 and increased genes by OLT-2 were involved in Group B, C, D. In biological process, expression of genes involved in cytokine or cell calcium signaling, such as interleukin 18 and G-protein beta 4 were increased, but protein tyrosine phosphatase receptor type c, which function is cell adhesion between antigen-presenting cell and T or B-cell, was decreased by OLT-2. This study provides the most comprehensive available survey of gene expression changes in response to anti-leukemia effect of OLT-2 in human blood.

The root of Astragalus membranaceus Bunge (Leguminosae) has been used in the Korean oriental medicine for strengthening the vital energy. UV irradiation has been suggested as a major cause of photo aging in skin. In order to investigate protective effects against UV induced cellular damage, Astragali Radix was extracted with 70% ethanol and dissolved in DMSO. The protective effect was detected by MTT assay, LDH assay, and Comet assay in immortalized human keratinocyte cell line, HaCaT cell system after UV irradiation. Astragli Radix 70% EtOH extract reduced UV induced cellular damage in cell survival, membrane integrity and DNA damage.

Solvent fractions were prepared from traditional herbal drugs which of methanol extracts inhibited $CCl_4$-induced cytotoxicity in primary cultured rat hepatocytes and c ontinuously assayed their effects. Ethylacetate and n-buthanol fractions from Cibotii Rhizoma and chloroform fraction from Gelatina Nigra inhibited the release of LDH and GPT from $CCl_4$-treated hepatocytes, respectively. Water fraction (WAR) among solvent fractions from Astragali Radix showed the most potent inhibitory effect on the release of GOT or GPT by treatment with $CCl_4$. All of solvent fractions prepared from Eucommiae Cortex had no effect on $CCl_4$-induced cytotoxicity. Chloroform and ethylacetate fractions from Rehmanniae Radix Preparata increased the release of GPT from $CCl_4$-treated hepatocytes. n-Hexan, chloroform or ethylacetate fraction from 5 herbal drugs increased the release of LDH, GOT or GPT from normal hepatocytes at the dose of 1.Omg/ml. Administration of WAR suppressed the elevation of GOT, ALP activities and MDA contents in the serum as well as in the liver tissue of $CCl_4$-intoxicated rats. Based on these results, isolation of antihepatotoxic substances from WAR is under the process.

Effects of Astragali radix extract (AG) on the humoral immunotoxic responses of zinc chloride (Zn) were studied in ICR mice. Mice were divided into 4 groups (10 mice/group), and Zn was given to the mice, 1 hr after i.p. injection with 0.5 g/kg of AG, by i.p. injection daily for 10 days at a dose of 25 mg/kg. Mice were immunized and challenged with sheep red blood cells (SRBC). Zn treatment increased the relative weight of spleen compared with those in controls, but decreased the hemagglutination (HA) titer 2-mercaptoethanol-resistant HA (MER-HA) titer and splenic plaque forming cells (PFC). AG treatment significantly increased the relative weight of spleen, HA titer and PFC compared with those in controls. Combination of Zn and AG significantly increased the relative weight of spleen compared with those in controls, but decreased the HA titer, MER-HA titer and PFC. The relative weight of spleen was significantly increased in the Zn and AG combination group than those in Zn alone treatment group. But the HA titer, MER-HA titer and PFC were slightly increased in the group of combination. These results suggest that AG might slightly restore humoral immune responses lowered by an excess of zinc.
