        The purpose of this experiment was designed to investigate the effects of medicinal herbs (MH) extracts on dementia induced by trimethyltin chloride (TMT) in rats. Six-week-old male Sprague-Dawley rats were randomly divided into five groups; normal group (group 1), control group (group 2), MH extracts group (250, 500 mg/kg) (group 3, group 4) and positive control group (tacrine group, group 5). In the control group to induce dementia, a 2.5 mg/kg of TMT intraperitoneal injection was used for 14 days (1 per day) in the rats. In the MH extracts group 250 mg/kg and 500 mg/kg of MH extracts were medicated in an oral inoculation for 20 days (1 per day). After 30 minutes, a 2.5 mg/kg of TMT intraperitoneal injection, which causes dementia, was used for 14 days (1 per day). In the positive control group (Tacrine group) 10 mg/kg of Tacrine, the dementia treatment, was medicated in an oral inoculation. After 30 mintues, 1 mg/kg of TMT intraperitoneal injection, which causes dementia, was used for 14 days (1 per day). The present author observed the passive avoidance performance test, and memory ability test (Y maze test), the values of MDA, acetlycholinesterase (AchE) activity in the brain and antioxidant enzyme in serum. MH extracts significantly improved memory of AD model rats in the Y-maze test, and also significantly improved memory of AD model rats in the passive avoidance test. MH extracts significantly reduced AChE activity, and significantly increased the SOD level, but not catalase and MDA. From the results above, MH extracts is thought to be effective in the improvement of antioxidant enzymes and memory ability.

        Background:The study was conducted to investigate the distributions of faecal bacteria in commercial oriental medicine herb products.Methods and Results:A survey was conducted on the microbial contamination levels and antimicrobial specificity of Bacillus cereus and other microbes using 106 oriental medicine herb products on sale in Seoul. Pouring and isolation methods such as standard plate counts were used to identify the bacteria. The isolated bacterias included coliforms, Bacillus spp., Enterococcus spp., Staphylococcus spp., Listeria spp.were identified by using gram staining and an API (analytical profile index) kit. Antimicrobial drugs discs were determined by CLSI (clinical and laboratory standards institute).Conclusions:The bacterial isolates present in the herbal medicines included 98 coliforms, 45 Bacillus spp., 29 Enterococcus spp., and 2 Listeria spp. Among these, there were nine Bacillus cereus strains, one Enterococcus faecium strain, and one Enterococcus faecalis strain present. The 9 Bacillus cereus strains were tested for susceptibility to 36 types of antibiotics products by the disc diffusion method. The strains showed resistance to 13 of these antibiotic products and semi-resistance to 5 antibiotic products. On the basis of these results, any oriental medicine herb product can be assumed to be contain resistant or semi-resistant bacterial strains. Therefore, we suggest prescribing guidelines and special management for the use of antibiotics in farms producing oriental medicine herb products.

        Background : Five medicinal herbs have been selected from the preliminary screening for in vitro anti-allergy activity (in RBL-2H3 cells). The present study is conducted to investigate the inhibitory effects of the medicinal herbs on allergic inflammation in other kind of cells. Methods and Results : Cells treated with five extracts prepared from Betula costata Trautv. (aerial part), Camellia sinensis L. (aerial part), Polygonatum stenophyllum Maxim. (root), Pyrus pyrifolia var. culta (Makino) Nakai (leaf), and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud. (root) were measured for mRNA levels of TNF-α on HaCaT keratinocytes stimulated by TNF-α /INF-γ and for mRNA levels of IL-2 in Jurkat T cells mediated by PMA/A23187. Pre-treatment with the five extracts reduced the mRNA levels of TNF-α in HaCaT cells and mRNA levels of IL-2 in Jurkat T cells. In particular, the leaf extract of Pyrus pyrifolia var. culta (Makino) Nakai significantly and dose-dependently decreased the mRNA levels of TNF-α and IL-2. To determine the toxicity of the extracts from the selected medicinal herbs to HaCaT cells and Jurkat T cells, the viabilities of the cells treated with several concentrations of the five extracts were measured by MTT assay. Extracts of Polygonatum stenophyllum Maxim. (root), Pyrus pyrifolia var. culta (Makino) Nakai (leaf), and Rehmannia glutinosa (Gaertn.) Libosch. ex Steud. (root) (up to 250 ㎍/㎖) did not show cytotoxic effects on HaCaT cells and Jurkat T cells. On the other hand, 250 ㎍/㎖ of extracts of Betula costata Trautv. (aerial part) and Camellia sinensis L. (aerial part) reduced cell viability in both cells. Conclusion : These results demonstrate that the leaf extract of Pyrus pyrifolia var. culta (Makino) Nakai has an anti-inflammatory effect by inhibiting pro-inflammatory cytokine expression. Therefore, the leaf of Pyrus pyrifolia var. culta (Makino) Nakai can be a useful resource for the development of anti-allergy/anti-inflammatory materials.
