Streptococcus mutans is considered one of the primary etiologic agents of dental caries. we studied the effect of the ethanol extracts of Tribuli fructus (T. fructus) on the growth, biofilm formation, acid production, adhesion and insoluble glucan synthesis of S. mutans. The ethanol extracts of T. fructus showed concentration dependent inhibitory activity against the growth and acid production of S. mutans, and produced significant inhibition at the concentration of 0.025, 0.05, 0.1, 0.2, 0.3, 0.5 mg/ml compared to the control group. In the biofilm assay, the ethanol extracts of T. fructus inhibited formation of biofilm synthesized by S. mutans at the concentration of 0.05 mg/ml. The extracts markedly inhibited S. mutans adherence to HA treated with saliva, and cell adherence was repressed by more than 50% at the concentration 0.05 mg/ml. On the activity of glucosyltransferase which synthesizes water insoluble glucan form sucrose, ethanol extract of T. fructus showed more than 10% inhibition over the concentration of 0.025 mg/ml. Hence, we conclude that T. fructus might be a candidate of anticaries agent. Further studies are necessary to clarify the active constituents of T. fructus responsible for such biomolecular activities.

Objectives : Peroxynitrite $(ONOO^-)$, superoxide anion radical $({\cdot}O_2^-)$ and nitric oxide (NO) are cytotoxic because they can oxidize several cellular components such as proteins, lipids and DNA. They have been implicated in the aging processes, and age-related diseases such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate the $ONOO^-$, NO, and $({\cdot}O_2^-)$ scavenging and anti-inflammatory activities of Mori Fructus in ob/ob mice. Methods : Mice were grouped and treated for 5 weeks as follows. Both the normal lean (C57/BL6J black mice) and control obese (ob/ob mice) groups received the standard chow. The experimental groups were fed a diet of chow supplemented with 7.5, 15 and 30 mg Mori Fructus per 1 kg of body weight for 14 days. For this study, the fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Western blotting was performed using anti-phospho $I{\kappa}B-\alpha$, anti-IKK-$\alpha$, anti-NF-${\kappa}B$ (p50, p65), anti-COX-2 and anti-iNOS respectively. Results : Mori Fructus inhibited the generation of $ONOO^-$, NO and $({\cdot}O_2^-)$ in the lipopolysaccharide (LPS)-treated mouse kidney postmitochondria in vitro. The generation of $ONOO^-$, NO and $({\cdot}O2^-)$ were inhibited in the Mori Fructus-administered ob/ob mice groups. The GSH/GSSG ratio decreased in the ob/ob mice, whereas they improved in the Mori Fructus-administered groups. Mori Fructus inhibited the expression of phospho $I{\kappa}B-\alpha$, IKK-$\alpha$, COX-2, iNOS genes, and thereby the activation of NF-$I{\kappa}B$. Conclusions : These results suggest that Mori Fructus is an effective $ONOO^-$, $({\cdot}O_2^-)$ and NO scavenger, and therefore it might be a potential therapeutic drug against the inflammation process and inflammation-related diseases.

Objectives The purpose of this study is to investigate the effects of Crataegi Fructus Pharmacopuncture(CFP) on the adipogenesis in 3T3-L1 cells, lipolysis in rat epididymal adipocytes and histological changes in porcine adipose tissue. Methods Inhibiton of preadipocyte differentiation and/or stimulation of lipolysis play important roles in reducing obesity. 3T3-L1 preadipocytes were differentiated with adipogenic reagents by incubating for 3days in the absence or presence of CFP ranging from 0.01 to 1mg/mL. The effect of CFP on adipogenesis was examined by measuring GPDH activity and by Oil Red O staining. Mature adipocytes from rat epididymal fat pad was incubated with CFP ranging from 0.01 to 1mg/mL for 3 hrs. The effect of CFP on lipolysis was examined by measuring free glycerol released. Fat tissue from pig skin was injected with CFP ranging from 0.1 to 10mg/mL to examine the effect of CFP on histological changes under light microscopy. Results The following results were obtained from present study on adipogenesis of preadipocytes, lipolysis of adipocytes and histological changes in fat tissue. 1. Crataegi Fructus Pharmacopuncture inhibited adipogenic differentiation at the concentration of 1.0mg/mL. 2. Crataegi Fructus Pharmacopuncture decreased the activity of glycerol-3-phosphate dehydrogenase(GPDH) at the concentration of 0.1mg/mL. 3. Crataegi Fructus Pharmacopuncture ok. lipolysis at the concentration of 0.1mg/ml. 4. Crataegi Fructus Pharmacopuncture ranging 0.1 to 10mg/mL failed to exert lysis of cell membrane in porcine fat tissue. Conclusions These results suggest that Crataegi Fructus Pharmacopuncture at relatively high concentration inhibited adipogenesis and increased lipolysis of adipocytes. However, Crataegi Fructus Pharmacopuncture didn't exert any effect on lysis of cell membrane in fat tissue.
