This study was aimed to evaluate the cavernosal relaxation effect of Crataegii fructus(CF) in the contracted rabbit penile corpus cavernosum by agonists.In order to study the effect of CF on the vasoconstriction of rabbit penile corpus cavernosum, isolated rabbit penile corpus cavernosum tissues were used for the experiment using organ baths containing Krebs solution.To investigate the cavernosal relaxation of CF, CF extract at $0.01{\sim}3.0mg/m{\ell}$ was added after penile corpus cavernosum were contracted by norepinephrine(NE) $1{\mu}M$. To analyze the mechanism of CF's vasorelaxation, CF extract infused into contracted penile tissues by NE after each treatment of indomethacin(IM), $N{\omega}$-nitro-L-arginine(L-NNA), methylene blue(MB), tetraethylammonium chloride(TEA).To study the effect of CF on influx of extracellular calcium chloride($Ca^{2+}$) in penile tissues, in $Ca^{2+}$-free krebs solution, $Ca^{2+}$ 1 mM infused into contracted penile tissues by NE after pretreatment of CF. Cytotoxic activity of CF on human umbilical vein endothelial cell(HUVEC) was measured by MTT assay, and nitric oxide(NO) prodution was measured by Griess reagent. CF relaxed cavernosal strip with endothelium contracted by NE, but in the strips without endothelium, CF-induced relaxation was significantly inhibited. The pretreatment of L-NNA, MB, TEA decreased significantly on the cavernosal relaxation than not-treatment of them. But the pretreatment of IM had no significant effect on the cavernosal relaxation. In $Ca^{2+}$-free krebs solution, when $Ca^{2+}$ infused into contracted penile tissues by NE, pretreatment of CF inhibit contraction induced by adding $Ca^{2+}$.NO production wasn't increased by treatment of CF on HUVEC. This findings showed that CF is effective for the relaxation of rabbit penile corpus cavernosum, and we suggest that CF relax rabbit corpus cavernosal smooth muscle through multiple action mechanisms that include increasing the release of nitric oxide from corporal sinusoidal endothelium, inhibition of $Ca^{2+}$ mobilization into cytosol from the extracellular fluid, and maybe a hyperpolarizing action.

Two of the essential processes required for metastasis are neoangiogenesis and tumor cell invasion of basement membranes (BM) and extracellular matrix (ECM). Recently, data showed that herbs removing blood stasis has an anti-angiogenic effects. Tonifying vital Qi and eliminating pathogenic factor was a basic modality in Oriental oncology. In this study, we investigated several Qi and Blood tonics for potent angiogenic inhibitors. Methanol extracts of samples inhibited the proliferation of ECV-304 at the concentration of 100 ${\mu}g/m{\ell}$. Zizyphi Fructus, Glycyrrhizae Radix, Angelicae Gigantis Radix decreased the gelatinolytic activity of MMP-9 from ECV-304, at the concentration of 100 ${\mu}g/m{\ell}$ in gelatin zymography. In in vitro invasion assay, herbs inhibited the invasion activity of ECV-304 by 53% of control (Ginseng Radix), 39% (Zizyphi Fructus), 36% (Angelicae Gigantis Radix), 25% (Glycyrrhizae Radix). Ginseng Radix inhibited the capillary-like tube formation of ECV-304 at the concentration of 160 ${\mu}g/m{\ell}$, Angelicae Gigantis Radix and Paeoniae Radix Alba inhibited at the concentration of 320 ${\mu}g/m{\ell}$. These results indicated that Ginseng Radix, Glycyrrhizae Radix, and Angelicae Gigantis Radix could be considered as potent angiogenic inhibitiors.

Rosa rugosa has been used as a folk medicine with various pharmacological properties for a long time in Asia. Recently, it has been reported that the extract of fractions from different parts of Rosa rugosa have various pharmacological effects on diverse diseases including diabetes, inflammatory diseases and tumor. We investigated effects of fructus extracts of Rosa rugosa(RRF) and semen extracts of this herb(RRS) on macrophage to evaluate the possibilities as a biological response modifier. We showed increased effects on tumoricidal activity, phagocytic activity, TNF-$\alpha$ and NO production in RRF-treated groups without direct tumor cell cytotoxicity. RRS-treated groups increased direct tumor cell cytotoxicity at high dose without tumoricial activity except increasing of TNF-$\alpha$ release. These results provide further possibilities for the beneficial immunomodulating effects of RRF on immune system with relatively larger safety margin rather than RRS.

In this study, we investigated the quality characteristics of yogurt with different amounts(0.5, 1.0, 1.5, 2.0%) of Sansuyu(Corni Fructus) extracts. The yogurt products were evaluated for sensory properties, acid production(pH, titratable acidity) and the number of viable cells during storage up to 21 days at $10^{\circ}C$. The products containing 0.5% and 1.0% Sansuyu extracts showed the highest scores for color, smell, softness, taste, and overall acceptability. For the intensity characteristic scores, color, smell and bitter taste increased as the proportion of Sansuyu extract increased. Softness was lowest, but it was highest in the 0.5% and 1.0% Sansuyu extracts. During storage, titratable acidity increased while pH gradually decreased. pH was lower in the sample with Sansuyu extract than that of the control, and the titratable acidity increased with increasing Sansuyu extract content on day 0. There was significant difference in viable cell counts among the samples. These results indicated that the yogurt added with 0.5~1.0% Sansuyu extract was acceptable.
