The effects of an Acanthopanacis cortex water extract on lipid levels, lipid peroxide, total antioxidant status and antioxidant enzyme activities were evaluated in rats fed one of the following diets for six weeks: normal diet and deionized water (ND), normal diet and Acanthopanacis cortex water extract (NDC), high fat diet and deionized water (HFD), high fat diet and Acanthopanacis cortex water extract (HFDC). The food intakes were significantly lower, but the food efficiency ratios were significantly higher in the high fat diet groups. The level of HDL-cholesterol in the plasma was significantly increased and the levels of LDL-cholesterol and triglyceride in the plasma were significantly decreased by the Acanthopanacis cortex water extract in the high fat diet groups. As a a result, the AI (atherogenic index) and CRF (cardiac risk factor) were significantly lower in the high fat diet groups that were treated with Acanthopanacis cortex water extract. The triglyceride and the total cholesterol of the liver were also significantly upregulated in the high fat diet groups, while the total cholesterol of the liver decreased in response to treatment with Acanthopanacis cortex water extract (HFDC). The plasma and liver concentrations of thiobarbituric acid reactive substances (TBARS) were significantly reduced by the addition of Acanthopanacis cortex water extract to the normal diet groups. The total antioxidant status (TAS) in the plasma was significantly upregulated by adding Acanthopanacis cortex water extract to the high fat diet groups. The activities of SOD, catalase and GST were also significantly higher in the Acanthopanacis cortex water extract groups when compared to the ionized water groups. The activity of GSH-Px and the concentration of GSH in the liver were significantly higher following the addition of Acanthopanacis cortex water extract to the high fat diet groups. Taken together, these results suggest that a supplementation of the diet of rats fed a high fat diet with Acanthopanacis cortex water extract improves lipid metabolism, reduces lipid peroxide and improves the activities of antioxidant enzymes, which may have favorable effects on antioxidant systems by improving the total antioxidant status (TAS).

Immunological activities of the combined-administration of Acanthopanacis Cortex and Lycii Cortex Radicis were examined in BALB/C mice. The 40% ethyl alcohol extract of Acanthopanacis Corter (AE) or the 40% ethyl alcohol extract of Acanthopanacis Coriex and Lycii Cortex Radicis (ALE) were administered p.o. once a day for 7 days, respectively. AE did not affect the viability of thymocytes, but ALE decreased the viability of thymocytes. ALE enhanced the viability of splenocytes increased by AE. Also, AE enhanced the population of cytotoxic T cell in thymocytes, and ALE enhanced the population of helper T cell compared with AE. Furthermore, AE increased the population of $Thy1^+$ cells in splenocytes, and increased the population of splenic $CD4^+$ cells. In addition, ALE enhanced the phagocytic activity which was decreased by AE ALE decreased the production of nitric oxide increased by AE in peritoneal macrophages. These results suggest that ALE enhance an immune-regulative action of AE.

This experimental study was carried out to evaluate the effects of Acanthopanacis cortex on Cytokine-inducing and and immune response in Mice. In order to investigate the effect of Acanthopanacis cortex, the following was performed; Cytotoxicity, in vitro, the fraction of $CD4^+$, $CD8^+$, $B220^+$ in splenic cell, gene expression of IL-12(p35), IL-12(p40), IFN-${\gamma}$, and splenic cell proliferation by Acanthopanacis cortex. Analysis of cytokine gene expression was carried out by RT-PCR amplification. Amplified PCR products were electrophoresed on 1.2% agarose gel, and the analysis (Ht) was used to 1D-density program. The results were obtained as follows. Acanthpanacis cortex showed didn't have cell toxicity under $12{\mu}g/m{\ell}$ group on mouse lung fibroblast cells. In an in vitro model using mouse peripheral blood mononuclear cells (PBMCs), extract of Acanthpanacis cortex induced multiple cytokine, including interleukin-12 (p35), interleukin-12 (p40), interferon-gamma (IFN-${\gamma}$). The extract also enhanced the percentages of the $CD4^+$, and $CD8^+$ in the untreated control were $22.1{\pm}3.3$ to $38.4{\pm}2.1$, and $5.0{\pm}0.4$ to $10.7{\pm}0.3%$, respectively. From above findings, it is suggested that Acanthopanacis cortex is able to anti-cancer and activate immune response system.

We obtained 4 kinds of extract fraction from Acanthopanacis Radicis Cortex and studied on the influence to the blood pressure of rabbit. These 4 fractions were obtained as follows; Fraction I was insoluble fraction by 99% ethanol from 80% methanol extract of Acanthopanacis Radicis Cortex, fraction II, precipitated fraction by ether from 99% ethanol soluble fraction of 80% methanol extract of Acanthopanaacis Radicis Cortex, fraction III, no precipitated fraction by ether from 99% ethanol soluble fraction of above 80% methanol extract and fraction IV, water extract of Acanthopanacis Radicis Cortex. All of fractions, when administered into ear-vein of rabbit, produced fall of blood pressure. Among these 4 fractions, although fraction III was not only the most potent but had the greatest efficacy, we observed the mechanism of hypotensive action of Acanthopanacis Radicis Cortex, making use of fraction II which was thought as a comparatively pure fraction. Hypotensive action of fraction II (APF II) was not affected by vagotominization but markedly inhibited by atropine. Pretreatment of bethanidine showed a tendency to weaken the depressor action of APF II, although it was not a significant result, but diphenhydramine did not influence APF II action. Phentolamine, guanethidine and chlorisondamine inhibited significantly the hypotensive action of APF II. APF II elicited the potentiation of norepinphrine pressor action dependent on the time-factor whereas it did not influence angiotesin pressor action. It is seemed that APF II exhibited hypotensive action, causing peripheral muscarinic-effect and centrally induced sympatholytic action.

This study was aimed to examine relaxing effects of Acanthopanacis cortex(AC) through nitric oxide(NO) production and phosphodiesterase type 5(PDE-5) inhibition in corpus cavernosum. In order to define the relaxation effects of AC extract, rabbit corpus cavernous tissues were prepared in $2{\times}2{\times}8mm$ sized strip. AC extract ($0.01-3.0mg/m{\ell}$) were treated in contracted strips induced by phenylephrine(PE) and $N{\omega}$-nitro-L-arginine (L-NNA) was treated before AC extract-treated. And calcium chloride($Ca^{2+}$) 1 mM was infused into precontracted strips after pretreatment of AC extract in $Ca^{2+}-free$ krebs-ringer solution. When AC extract was applied to human umbilical vein endothelial cell(HUVEC), cell viability was measured by MTT assay, and NO concentration was measured by Griess reagent system. Ratio of smooth muscles to collagen fibers and eNOS, PDE-5 positive reaction were measured by histochemical and immunohistochemical process on mice corpus cavernosum. AC extract significantly affected relaxion of the cavernous strips, and the pretreatment of L-NNA inhibited AC extract-induced relaxation. Contraction induced by the addition of $Ca^{2+}$ was inhibited by treatment with the AC extract in $Ca^{2+}-free$ solution. In AC group, NO concentration, ratio of smooth muscle to collagen fibers, and eNOS positive reaction were increased, PDE-5 positive reaction was decreased compared to PE group. As a result of the above experiment, it was thought that AC extract inhibits the inflow of extracellular $Ca^{2+}$ by activating cGMP through the increase of eNOS / NO and the decrease of PDE-5 which inhibits cGMP activity, in the corpus cavernosum.
