The GC pictures were taken to investigate the difference between the Zingiberis Rhizoma and the Zingiberis Rhizoma Recens. For the Zingiberis Rhizoma Recens, there were many peaks in the GC pictures of the juice of that, but the decoction of that had vanished many big peaks and shown many new peaks. This result suggested that many elements had been created from the other elements. For the Zingiberis Rhizoma, even though it was similar to the decoction of the Zingiberis Rhizoma Recens, that had vanished many peaks. This result suggested that many elements had been vanished during the drying period.

We have examined the induction of HL-60 cell differentiation by treatment of the water extract of Rhizoma Zingiberis Siccatum, which is a Korean traditional herbal medicine. It was observed that HL-60 cell proliferation was dose-dependently inhibited by treatment with various dose of Rhizoma Zingiberis Siccatum extract. The level of inhibition was identical to those of ATRA-treated cells. Rhizoma Zingiberis Siccatum extract treatment caused a significant change in NBT reduction (47%) and enhanced ATRA-induced NBT reduction. Treatment of Rhizoma Zingiberis Siccatum to HL-60 cells increased only CD11 b expression in the cells, and also increased markedly G0/G1 stage arrest. This can suggest that Rhizoma Zingiberis Siccatum induced the differentiation of HL-60 cell and enhanced ATRA-induced differentiation predominantly along the granulocytic lineage. The results present here show that Rhizoma Zingiberis Siccatum extract contains the potential effect of differentiation induction or acts as a agent enhancing the induction of differentiation.

To develop optimal storage method of root of Zingiberis Rhizoma, which has been grown as major cultural herbal medicine materials, root of Zingiberis Rhizoma, was stored for 10 months with different packing materials and sealing methods. The loss in dry weight as influenced by packing materials and sealing methods was the lowest at vacuum packing and followed by complete sealing methods with transparent polyethylene film. The ratio of root rot during the storage period was not significantly different between packing materials but was significantly different between sealing conditions. Conclusionally, vacuum packing and complete sealing with polyethylene film appears to be optimal for storage of Zingiberis Rhizoma.

Objectives: This study was performed to investigate anti-obesity effects of Zingiberis Rhizoma on ovariectomized rats in order to determine the possibility of the clinical use in preventing and treating post-menopausal obesity. Methods: To investigate how menopause affects obesity in woman, rats were treated with Zingiberis Rhizoma extracts. We measured various biomarkers including GOT,GPT, leptin, ghrelin, adiponectin, $PPAR-{\gamma}$ mRNA, total cholesterol, triglyceride, HDL-cholesterol, liver weight, estradiol, uterine weight, and calcitonin, which are linked with obesity and menopause. Results: There was a significant decrease in group which was given Zingiberis Rhizoma extracts 100 mg/kg and lipid level found in blood(total cholesterol, triglyceride). Fat accumulation of liver cells was repressed, liver function was improved and leptin and adipomectin levels were significantly normalized. In addition, expression of $PPAR-{\gamma}$ was significantly increased. Conclusions: The results indicated that Zingiberis Rhizoma extracts have anti-obesity effects on ovariectomized rats through improving liver function and lipid metabolic function.

This study was conducted to investigate angiogenic inhibitory effect of Zingiberis Rhizoma methanol extract using ECV-304 cells and HT1080 fibrosarcoma cells. The viability of ECV-304 was 30% at 50㎍/㎖ of Zingiberis extract and that of HT1080 was 30% at 100㎍/㎖. Using the BrdU incorporation assay, Zingiberis inhibited the DNA synthesis of ECV-304 and HT1080 by 70% and 50% at 200㎍/㎖. In tube formation assay, at 10㎍/㎖ of Zingiberis, tube network began to degrade and at higher doses, it was completely destroyed. Zymography demonstrated that Zingiberis extract decreased MMP-9 at 10㎍/㎖ and higher doses remarkably inhibited the expression of MMP-9. These data indicate that Zingiberis Rhizoma has angiogenic inhibitory effects and shows the possibility of future anti-metastatic drug.

Objective : Hypothyroidism is a common disease of the endocrinal system. characterized by fatigue, cold intolerance, bradycardia, and so on. Clinically, Levothyroxine(L-T4) has been usually used for replacement therapy, but it often has side effects. so many hypothyroidism patients wants oriental medical therapy. Zingiberis rhizoma, traditionally has been used in treatment of coldness, fatigue, and bradycardia. In this study. I investigated the therapeutic effects of Zingiberis rhizoma on PTU induced hypothyroidism in rats. Methods : I used two-month-old rats administered PTU and induced with hypothyroidism. After 2 weeks. Zingiberis rhizoma and thyroxine were daily administered, respectively. Body weights was measured every weeks. After 4 weeks, blood samples were taken and analyzed biochemically and T4 and TSH were measured by ELISA kits. Results : In comparison with normal groups, control groups showed hypothyroidism with low T4 and high TSH level. In Zingibris rhizoma administration groups were observed T4 level elevation, this elevation was dependent on the dose of Zingibris rhizoma. Between experimental groups and control groups, there was no difference in TSH level, statistically. Changes of biochemistry were not observed in any experimental groups. Conclusions : These findings suggest that Zingiberis rhizoma makes thyroid cells producing thyroid hormones. There is also a non-toxic effect on the cardiovascular system, liver and kidney function. So, Zingiberis rhizoma should be an effective agents for treating hypothyroidism.
