Citrus fruits have been known to reduce the proliferation of many cancer cells. The antiproliferative effects of Citrus reticulata Blanco (CR) extract, the immature tangerine peel, on human gastric cancer cell line SNU-668 were evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, 4,6-diamidineo-2-phenylindole staining, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay, reverse transcription-polymerase chain reaction expressions of BCL-2, BAX and CASP-3 genes, caspase-3 activity, and immunocytochemistry of caspase-3. From the results of the morphological and biochemical assays, CR (50 microg/ml) increased the apoptosis of human gastric cancer cells with typical apoptotic characteristics, including morphological changes of chromatin condensation and apoptotic body formation. CR (50 microg/ml) reduced the expression of BCL-2, whereas the expression of BAX and CASP-3 was increased compared with the control group. Furthermore, caspase-3 activity and caspase-3 protein expression in the CR-treated group was significantly increased compared with that in control group. These results suggest that CR may induce the apoptosis through the caspase-3 pathway in human gastric cancer cells.

Angelicae Gigantis Radix (AGR) is one of the most widely used herbal medications. AGR is the dried root of Angelica gigas Nakai (Umbelliferae), which is known as Korean angelica. This study investigated the effects of AGR on osteoclast formation using primary bone marrow cells. TNF-alpha treatment increased tartrate-resistant acid phosphatase (Trap) positive cells and Trap activity in bone marrow cells. However, AGR significantly decreased both TNF-alpha-induced Trap positive cells and Trap activity. RT-PCR analyses revealed that AGR decreased mRNA levels of Trap and matrix metalloproteinase-9 in TNF-alpha-treated bone marrow cells. In addition, AGR decreased TNF-alpha-induced activation of NF-kappaB. These results suggest that AGR has an inhibitory effect on the formation of osteoclasts and its effect is partially related to the NF-kappaB pathway.

Objectives : The purpose of this study is to confirm the effects of external applications(CLANCHE SM A Clinic) containing herbal extracts on patient with atopic dermatitis.Methods : A total of 24 patients who visited Semyung Oriental Medical Center from January 15th, 2014 to February 20th, 2014 were included in the study. In this study, the patients were treated with external applications(CLANCHE SM A Clinic) containing herbal extracts. For 4 weeks of gross examination and instrumental assesment were made before and after the study.Results : 1. In the primary endpoint, SCORAD index showed a statistically significant decline. 2. In the secondary endpoint, index of skin hydration and index of TEWL showed statistical significance. 3. In the secondary endpoint, index of skin pH showed no statistically significant result.
