In recent, there are increasing reports about pharmacological activities of Crataegi Fructus which has been used for many centuries as medicinal and food sources in East Asia. However, its antifungal efficacy needs to be investigated. Thus, in the current study, we determined synergistic antifungal activity of the Crataegi Fructus extract (CFE) when combined with fluconazole (FLC) against disseminated candidiasis due to Candida albicans. This fungus is one of the most problematic fungal pathogens. Data resulting from a microdilution susceptibility test showed that CFE had a dose-dependent antifungal activity. When the extract was combined with FLC, the activity was synergistic. For example, the antifungal activity by the combination of CFE at $20{\mu}g/ml$ plus FLC at $0.1{\mu}g/ml$ was 4 times more effective than antifungal activity by FLC alone at the same concentration (P<0.05). In the murine model of disseminated candidiasis, the combination therapy potentiated resistance of mice, resulting in 80% of C. albicans-infected animals surviving the entire period of 40 days observation, whereas mice given CFE alone or FLC alone all died with 17 and 23 days, respectively, although they survived longer than the untreated control animals (P<0.05). The CFE's antifungal activity seemed to be related to the blockage of hyphal production of C. albicans yeast cells. In summary, CFE has a synergistic antifungal activity, which can be produced by combining CFE with FLC. Thus, our data strongly indicate that CFE may be a potential candidate as an antifungal agent for combination therapy.

To clerify the antioxidant effect of Crataegi Fructus (CF) extract on reactive oxygen species (ROS), The C6 glioma cells were treated with various concentrations of hydrogen peroxide ($H_2O_2$). The $H_2O_2$-induced neurotoxicity was measured by XTT assay for the cell viability. For the protective effect of CF extract on the cytotoxicity induced by $H_2O_2$, cell viability, lactate dehydroganase (LDH) activity, and the inhibitive activity of lipid peroxidation of CF extract were performed. In this study, $H_2O_2$ decreased cell viability dose- and time-dependent manners and increased LDH activity compared with the control. In the protective effect on $H_2O_2$, CF extract increased cell viability and decreased LDH activity on $H_2O_2$-induced cytotoxicity, lipid peroxidation by FTC assay. From these results, It is suggested that $H_2O_2$ was highly toxic on cultured C6 glioma cells, and also, CF extract showed the protective effect on $H_2O_2$-mediated cytotoxicity.

In this study, the dyeing properties and functionalities of Crataegi fructus extract were investigated for the purpose of application to new natural dye resources. The effects of dyeing conditions(concentration of dye, dye bath temperature, dyeing duration and dye bath pH) and mordanting on dye uptake and color changes were also examined. The study also estimated the colorfastness, antibacterial properties, and ultraviolet protection properties of the dyed and mordanted silk fabrics. The dye uptake increased in tandem with the dye concentration and dye bath temperature. The highest K/S values were obtained at the following conditions: a dye concentration of 100%(v/v), a dyeing period of 60 minutes, a dye bath temperature of $90^{\circ}C$, and a dyeing pH of 3. The colorfastness of the material when dry cleaned or rubbed ranged from good to excellent and fastness to light was rated at grade 2-3. The change in the color grade when exposed to washing was not good; however, the stain of washing fastness was good at a range of 4-5. In regards to the functional property aspects, the dyed and mordanted fabrics exhibited excellent results with a 99.9% reduction rate, and excellent ultraviolet protection factors.

It had been known for a while that Crataegi Fructus(CF; Crataegus pinnatifida Bunge) had only a digestive effect. Recently, it has been demonstrated that CF also has an anti-hypertensive effect. However, its mechanism of relaxant effect has not been investigated yet. This study was examined to investigate the mechanism of vascular relaxation effect of CF in isolated rat thoracic aorta. CF revealed significant relaxation to phenylephrine(PE)-induced arterial contraction but much less to KCI-induced one. When CF was pretreated, it inhibited PE-induced contraction non-competitively. Methylene blue(10/sup -6/M) completely blocked the relaxant effect of CF whereas L-NAME(10/sup -5/M) did almost completely. However, atropine(10/sup -6/M) did not have any influence on vascular relaxation effect of CF. Regarding cNOS activity, CF significantly increased its activity from rat whole brain homogenate in a dose dependent manner which was inhibited by L-NAME(10/sup -5/M). On the other hand, CF did not affect on expression of TNF-α mRNA in RAW 264.7 cells, suggesting that CF is not related to iNOS activity. These results indicate that CF would be effective in relaxing vascular contraction through release of endothelial nitric oxide.

Objectives : This study was carried out to investigate the effects of Crataegi Fructus water extract(CFWE) on hair growth in an alopecia model of C57BL/6N mice and human dermal papilla cells(hDPCs). Methods : Six-week old mice were depilated and separated in 3 groups ; CON, MXD(2% Minoxidil), and CFWE. The treatments were applied twice a day for 18 days. The hair growth was determined photographically. The hair density, thickness and length were identified by Folliscope and the weights of body were measured. In dorsal skin tissue, the expression of hair growth-related protein was analyzed by Western blot. In hDPCs with/without $IFN-{\gamma}$, cell proliferation and the expression of hair growth-related genes were analyzed. Results : We observed that CFWE promoted hair growth compared to CON. CFWE improved the hair density, thickness and length compared to CON. CFWE increased the $Wnt/{\beta}$-catenin signaling in dorsal skin. In hDPCs, CFWE accelerated the cell proliferation and inhibited $IFN-{\gamma}$-induced hDPCs degeneration. CFWE increased the mRNA expression of ${\beta}$-catenin, Axin-2, BMP-4, FGF-7, FGF-10, and ALP compared to CON and $IFN-{\gamma}$ treated cells. Conclusions : These results suggest that CFWE has a hair regrowth activity via $Wnt/{\beta}$-catenin signaling and can be useful for the treatment of alopecia.

Objectives: To investigate the effect of fermented extract of Artemisiae Iwayomogii Herba, Curcumae Longae, Crataegi Fructus and Salviae Miltiorrhizae Radix (FMH) on anti-inflammation associated with dyslipidemia and anti-oxidation in RAW264.7 and HUVEC cells. Methods: The total polyphenols, total flavonoids, DPPH radical scavenging activity, ABTS radical scavenging activity, and cytotoxicity of FMH were measured. RAW264.7 cells treated with FMH were tested for production of NO, and for cytokine and LTB4 levels and HUVEC cells treated with FMH were examined for production of cDNA of genes related to inflammation. Results: 1. FMH contained polyphenols and flavonoids. The DPPH and ABTS radical scavenging activity of FMH increased in a concentration-dependent manner. 2. FMH treatment inhibited the production of nitric oxide (NO), cytokines, and LTB4 in RAW264.7 cell when compared to the untreated control group. 3. FMH decreased the transcription of pro-inflammatory genes, whereas it increased transcription of anti-inflammatory genes, in HUVEC cells. Conclusion: FMH is effective as an antioxidant and for treatment and prevention of dyslipidemia, atherosclerosis, ischemic heart disease, stroke, and other cardiocerebrovascular diseases.
