The aim of this study was to study the quantitative analysis of glycyrrhizic acid in Glycyrrhizae Radix extract fermented with Paecilomyces japonica, Ganoderma lucidum, honey or Nuruk. The amounts of dry on loss were measured and the quantitative analysis of glycyrrhizic acid was performed by high performance liquid chromatographic (HPLC). HPLC method was performed on C18 column ($250\;mm\;{\times}\;4.6\;mm$, $5\;{\mu}m$, RS tech) using gradient solvent mixtures of water-acetonitrile with photodiode array detector (254 nm). The flow rate was $1.0\;m{\ell}/min$. Retention time of glycyrrhizic acid was about 23.96 min and linearity of calibration was $R^2$=0.9998. Contents of glycyrrhizic acid in Glycyrrhizae Radix extract (control) was $5.048\;{\pm}\;0.14$; Contents of glycyrrhizic acid in Glycyrrhizae Radix extract fermented with Paecilomyces japonica (SDT) was $1.975\;{\pm}\;0.07$; Contents of glycyrrhizic acid in Glycyrrhizae Radix extract fermented with Ganoderma lucidum (SYT) was $2.676 \;{\pm}\;0.07$; Contents of glycyrrhizic acid in Glycyrrhizae Radix extract fermented with honey (SST) was $5.191\;{\pm}\;0.06$; Contents of glycyrrhizic acid in Glycyrrhizae Radix extract fermented with Nuruk (SNT) was $5.305\;{\pm}\;0.34$, respectively. Contents of glycyrrhizic acid in SDT and SYT were decreased but that in SST and SNT was increased when compared to control.

This study was performed to investigate the effects of fermented extract of Pinus densiflora (FPD) on oxygen radicals and $H_2O_2$-induced damage. The results are as follows: 1. The 1.1-diphenyl-2-picrylhydrazyl (DPPH) free radicals were considerably reduced by FPD and $IC_{50}$ value was showed the concentration of 20 ㎍／㎖. 2. The cytotoxicity did not observe by FPD treatment in A548 cells. 3. The $H_2O_2$-induced cell damage was recovered by FPD pretreatment in A549 cells. These results suggest that FPD, as a natural antioxidant, has scavenging effect of free radicals and protection effect from $H_2O_2$-induced cytotoxicity.

Objectives : The purpose of this study was to investigate the influence of modified fasting therapy using fermented herbal medicine on the changes of body compositions. Methods : This study was carried out on 11 patients who carried out modified fasting therapy using fermented herbal medicine. They went through reducing food intakes period(7 days), fasting period(10~14 days) and refeeding period(10~14 days). Body compositions(weight, BMI(body mass index), skeletal muscle mass, body fat mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were measured at each state. And then the data was analyzed. Results : 1. The weight and BMI decreased during the reducing food intakes period and the fasting period, and increased during the refeeding period. But the weight and BMI decreased during the fasting therapy period, as a whole. 2. The skeletal muscle mass decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of skeletal muscle mass didn't show significance. The body fat mass and percent body fat decreased during the reducing food intakes period, the fasting period and the refeeding period. 3. The basal metabolic rate decreased during the fasting period and increased during the refeeding period. As the final outcome, for the whole fasting therapy period, decrease of basal metabolic rate didn't show significance. 4. The waist-hip ratio decreased during the fasting period and the refeeding period. The visceral fat area decreased during the fasting period and refeeding period. Conclusions : Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions. This results are expected to compensate the defects of existing fasting therapy.

Objective : Lonicerae Flos has detoxifying properties and been used as antipyretic, antibacterial and antitumor. Fermentation of herbal medicine is known to increase the absorption, enhance effectiveness, decrease herbal toxicity and reduce side-effects. This study was performed to measure the effects of fermented Lonicerae Flos on influenza A/WSN (H1N1) virus replication. Material and Methods : Lonicerae Flos was fermented by Lactobacillus casei PM1. Fermented Lonicerae Flos was treated for 12 hours to MDCK (Mardin Darby canine kidney) cells, then cell-virulence was observed by MTT assay for 12 hours, 24 hours, and 36 hours after treatment. Following cases were conducted for 0, 10, 100, and $1000{\mu}g/ml$ concentrations of fermented Lonicerae Flos under the same time-frame; the fermented Lonicerae Flos was treated to MDCK cells before and after contamination by A-type influenza virus. The fermented Lonicerae Flos and the virus were mixed directly. The influence was observed by MTT assay and plaque assay. Results : These findings suggest that the fermented Lonicerae Flos inhibited the virulence of influenza A virus in MDCK cells and suppressed the plaque forming colonies induced by influenza A virus. Furthermore, pretreatment with fermented Lonicerae Flos was more effective than post-treatment. The titer of influenza virus was reduced for all before and after influenza A virus inoculation.

Insampaedoksan (IS) is the decoction of medicinal herbs, which was commonly used for anti-inflammatory and anti-pyretic in the Korean traditional medicine (KTM). Several studies on improving efficiency or searching new efficiency by fermenting traditional herbal medicines are recently in progress. The bioconversion has been conducted on IS using various bacteria. Liquiritin, ferulic acid, hesperidin, liquiritigenin, and glycyrrhizin in IS before and after fermented IS were simultaneously analyzed. These compounds were qualitatively analyzed and quantitatively analyzed using the HPLC-DAD system. The identifications of liquiritin, ferulic acid, hesperidin, liquiritigenin and glycyrrhizin were achieved by comparing the HPLC retention time ($R_t$) and the UV absorption of five pure compounds in the IS. As a result, the increased constituents were identified to be liquiritin, liquiritigenin and glycyrrhizin, while the decreased constituent was ferulic acid and the constituent of hesperidin was similar to before and after fermentation. Insampeadock-san fermented by Lactobacillus plantarum KFRI 144 exhibited the most remarkable changes in all of fermentation.

Objectives : Samchulgeonbi-tang (shenzhujianpi-tang) has been prescribed as one of traditional herbal medicine for treatment of stomach diseases since ancient time in Korea. Samchulgeonbi-tang extract was fermented by Lactobacillus spp. for improving the effect. However, the toxicity and safety of fermented Samchulgeonbi-tang (FS) extract were not confirmed. Therefore, this study was performed to evaluate the acute toxicity and safety of FS extract. Methods : To evaluate the acute toxicity and safety of FS extract, several doses of FS extract, 0, 500, 1000 and 2000 mg/kg, were orally administered to 20 male and 20 female ICR mice, respectively. After treatment with FS extract, we observed mortality, general toxicity, behavior and change of body weight for the 14 days. After 14 days of oral administration, all mice were sacrificed and hematological parameters were analyzed from blood serum. Results : In present study, the toxic signs such as mortality or abnormal behaviors by FS extract were not observed. There are no significant differences between FS-treated group and control group in body weight, organ weights, and hematological parameters. Conclusions : The remarkable adverse effects by FS extract were not observed in ICR mice. Also, any death was not occurred at all treated FS doses, 500, 1000 and 2000 mg/kg. Therefore, the approximate lethal dose (ALD) of FS extract may be more than 2000 mg/kg.
