Bamboo salt(BS) is a traditional Korean food, and has been reported to have anti-cancer, anti-inflammatory, and anti-metastatic effects. However, the anti-atopic dermatitis(AD) activity of BS has not been described yet. In the present study, we examined the preventive effect of BS on AD. The effect of oral administration of BS was tested in a 2, 4-dinitrofluorobenzene(DNFB)-induced AD animal model, by histological analysis, enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction, caspase-1 assay, and Western blotting analysis. BS administration reduced the total clinical severity and scratching frequencies, compared with the AD group. In the serum of DNFB-induced AD mice, the levels of IgE, histamine, thymic stromal lymphopoietin(TSLP), interleukin(IL)-5, and IL-13 were significantly reduced by BS treatment. BS significantly reduced the protein and mRNA expression of TSLP, IL-6, and tumor necrosis factor-α in the AD skin lesions. BS markedly reduced the infiltration of inflammatory cells. Furthermore, the activation of caspase-1 was reduced by BS in the AD skin lesions. Our results suggested that BS should be considered as a candidate treatment for allergic inflammatory diseases including AD.

AIM: To study the mechanism of Je-Chun-Jun (JCJ)-inducing the apoptosis of the human cervical carcinoma, HeLa cells. METHODS: The cell viability was assessed using MTT assay. The optical density was measured at 570 nm. The caspase activity was measured using 50 mmol/L of fluorogenic substrate, AC-DEVD-AMC (caspase-3), AC-VEID-AMC (caspase-8) or AC-LEHD-AFC (caspase-9). To confirm the expression of proteins, Western blotting was performed. To detect the characteristic of apoptosis chromatin condensation, HeLa cells were stained with Hoechst 33258 in the presence of JCJ. For the cell cycle analysis, HeLa cells were incubated with Propidium iodide (PI) solution. Fluorescence intensity of cell cycle was measured using flow cytometry system. RESULTS: The loss of viability occurred following the exposure of 10 g/L JCJ. Cells treated with 10 g/L JCJ for 3 d exhibited the apoptotic morphology (brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining) and the reduction of cell volume. Cells incubated

AIM： To investigate the effect of Patrinia scabiosaefolia （PS） on the cholecystokinin （CCK） octapeptide-induced acute pancreatitis （AP） in rats.METHODS： Wistar rats weighing 240-260 g were divided into three groups：（1） Normal saline-treated group; （2） treatment with PS at 100 mg/kg group, in which PS was administered orally, followed by subcutaneous administration of 75μg/kg CCK octapeptide three times after 1, 3 and 5 h, and this whole procedure was repeated for 5 d; （3） treatment with saline group, in which the protocols were the same as in treatment group with PS. We determined the pancreatic weight/ body weight ratio, the levels of pancreatic HSP60, HSP72 and the secretion of pro-inflammatory cytokines. Repeated CCK octapeptide treatment resulted in the typical laboratory findings of experimentally induced pancreatitis.RESULTS： PS reduced the pancreatic weight/body weight ratio, the levels of serum amylase and lipase, and inhibited expressions of pro-inflammatory cytokines in the CCK octapeptide-induced AP. Furthermore, PS pretreatment increased the pancreatic levels of HSP60 and HSP72.CONCLUSION： Pretreatment with PS has an antiiinflammatory effect on CCK octapeptide-induced AP.
