Background : Nowadays asthma is considered to be the inflammatory disease characterized by airway hyperresponsiveness and pulmonary eosinophilia, and mediated by Th lymphocytes expressing the Th2 cytokine pattern. In many recent studies, molecular biological methods have been used to investigate the role of cytokines in pathogenesis and new therapeutic targets of asthma. Objective : We aimed to identify the effect of Armeniacae Arnarum Semen and Platycodi Radix on the transcriptional activities of cytokine IL-4, IL-5 and IL-6 involved in asthma model. Materials and Methods : RBL-2H3 cell lines were used. Cells were stimulated with calcium inophore for maximal gene expression. After 24 hours of Armeniacae Arnarum Semen and Platycodi Radix-treatment, total cellular RNAs were collected using Trizol solution method. Then transcriptional activities of IL-4, IL-S and IL-6 were measured by RT-PCR with electrophoresis. Results : In IL-4 study, Armeniacae Arnarum Semen treated group showed 48.4% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 45.4% of transcriptional activities compared to the control group. In IL-5 study, Armeniacae Arnarum Semen treated group showed 52.7%of transcriptional activities compared to the control group and Platycodi Radix treated group showed 60.2% of transcriptional activities compared to the control group. In IL-6 study, Armeniacae Amarum Semen treated group showed 42.3% of transcriptional activities compared to the control group and Platycodi Radix treated group showed 69.1% of transcriptional activities compared to the control group. Conclusion : This study shows that Armeniacae Arnarum Semen and Platycodi Radix have the inhibitory effect on the transcription of IL-4, IL-5 and IL-6 gene expression in RBL-2H3 cell lines.

Objectives: This study was designed to investigate the anti-obesity, anti-diabetic and anti-inflammatory effects of Platycodi radix on obese type 2 diabetes mouse model. Methods: Obese type 2 diabetes mouse model was induced by Surwit's high fat, high sucrose diet for 8 weeks. Models were divided into 4 groups of normal diet (ND, n=10), high fat and high sucrose diet (HFD, n=10), high fat and high sucrose diet with Platycodi radix (PR, n=10), and high fat and high sucrose diet with Metformin (Met, n=10). Body weights were measured every week. After 7 weeks fasting, blood sugar and oral glucose tolerance tests were conducted. After 8 weeks blood samples were taken from mouse hearts and analyzed biochemically. Lipid profile, fructosamine, leptin and weight of epididymal fat pad and liver were measured. Adipose tissue macrophage percentage was analyzed by fluorescence-activated cell sorting (FACS). Results: Compared with the HFD group, body weight, glucose level, fructosamine, weight of epididymal fat pad and adipose tissue macrophage percentage decreased in the PR group. Conclusions: These results suggest that Platycodi Radix has anti-obesity, anti-diabetic, and anti-inflammatory effects on obese type 2 diabetes mouse model.

This study examined the effects of Lactobacillus plantarum(LP) cultured in Platycodi Radix decoction(LPPR) on the expressions of NO and TNF-${\alpha}$ in mouse macrophage RAW264.7 cell line. Cells were stimulated with LP or LPPR (0.1, 1, and 10 bacteria/cell) in all assays. More NO was induced in LPPR than LPM at 0.1 and 1 of a LP: cell ratio. The iNOS mRNA expression was also enhanced in LPPR stimulated cells. TNF-${\alpha}$ was increased in LPPR stimulated cells at the protein and mRNA level compared with LPM. In conclusion, LP fermented in Platycodi Radix decoction induced stronger activity in NO and TNF in mouse macrophages than LPM. These results suggest that fermentation by Platycodi Radix can be useful in enhancing the immunostimulatory activity of LP.

Platycosides are the saponins in Platycodi Radix and they have several beneficial effects such as antiinflammatory and anti-obesity activities. This study was designed to determine the changes in the saponin composition in Platycodi Radix (platycosides) after being processed under steam and pressure and to investigate the anti-inflammatory effects of their extracts. The change of the platycoside compositions was investigated after 1, 2, 3, 6 and 9h heat processing of Platycodi Radices by using HPLC coupled with an evaporative light scattering detection (ELSD) system. After heat treatment ($125^{\circ}C$, 1, 2, 3, 6 and 9 h), the contents of several platycosides such as platycoside E, platycodin $D_3$, platycodin D, polygalacin D, and platycodin A decreased as the processing time was longer. While the total contents of the saponins decreased, the contents of deapi-forms of deapiplatycoside E, deapi-platycodin $D_3$, and deapi-platycodin D increased relatively. These results indicate that the linkage between apiose and xylose located at C-28 is labile to heat and pressure. The LPS-induced iNOS inhibitory activities of the samples treated for 1 and 2 hours were enhanced and after then, the activities were reduced. These results suggested that heat treatment of the samples affect the content of the total saponins and the saponin content may be the important criteria representing the anti-inflammatory activity.
