The aim of this study is to investigate the effect of Okchun-hwan on Diabetes Mellitus. We searched articles from Oasis and Chinese Academic Journals(CAJ) online databases. Searching keywords were '玉泉丸', '옥천환'. Among the articles published from January 2000 to September 2016, The 79 articles were found. After review the title, abstract and original, The five articles were selected finally to rule out a completely different prescriptions and an animal test articles. Okchun-hwan is effective in improving the symptoms(dry mouth and throat, fatigue, eat easy to hunger, shortness of breath, sweating, palpitation, cardiac heat, insomnia, and tongue)of a patient with deficiency of both qi and yin diagnosis(氣陰兩虛證) on Diabetes Mellitus, as well as act on protection of endothelial cells and regulation of insulin sensitivity, insulin resistance that cause the diabetic chronic vascular complications.

The effects of herbal medicine on type 2 diabetic animal model were investigated. Herbal medicine were composed with the addition of Coicis Semen into Okchun-san (OCS). Commelinae Herba into Gangsim-tang (GST). Scrophulariae Radix into Hyunsamsunki-san (HSK). and Erythrinae Cortex into Yukmijihuang-hwan (YMH). We evaluated anti-hyperglycemic and body weight reduction activity in diabetic db/db mice. The experimental animals were divided into six groups. as control group and five sample groups. Each 200mg/kg/day of OCS, GST, HSK and YMH was administered with orally for 14days long. 5mg/kg/day of acarbose was administered with orally for 14days long. On day 14, OCS-treated db/db mice had significantly lower fasting blood glucose levels compared to control group(296±25.9 versus 593±16.4mg/dl. p<0.001). During the 2 h intraperitoneal glucose tolerance test (IPGTT), all the sample groups were improved compared to control group but insignificantly. After 14days of extract treatment. body weight in control. YMH and acarbose groups were increased. but OCS. GST and HSK groups reduced. However. it did not significantly lower hemoglobin Alc(HbAlc) in blood of db/db mice. These result suggest that OCS could be effective on insulin-independent type 2 diabetes.

Based on the data from our previous studies, four new diabetic remedies were composed with the addition of Coicis Semen into Okchun-san (OCH), Commelinae Herba into Gangsim-tang (GST) , Scrophulariae Radix into Sunki-san (SKS), and Erythrinae Cortex into Yukmijihuang-hwan (YMG). The water extracts of these new remedies were treated in 3T3-L1 fibroblasts and adipocytes in order to investigate insulin-like substances and insulin sensitizers, respectively. With and without differentiation inducers, unmodified SKS (SKS-O) treatment induced 3T3-L1 fibroblasts into adipocytes more than the control. However, without inducers, YMG treatment, but not SKS, induced the differentiation more than the control among modified remedies. Without inducers, SKS, OCH as well as YMG increased the induction of differentiation from 3T3-L1 fibroblasts into adipocytes, compared to the control. The treatment of OCH and YMG with 1 ng/mL insulin increased glucose uptake much more than only insulin 1 ng/mL treatment. Thus, OCH and YMG contained increased insulin actions. In conclusions, the modified remedies, OCH and YMG, contained insulin-like substances and insulin sensitizers, and they can be improved the hypoglycemic effects.

Chemical analysis, measurement of pumping rates of 60 production wells and depth to water tables of 57 monitoring wells were carried to protect depletion of water resources and deterioration of water quality for the commercial portable ground-water. Borehole depth of production well averages 149m(31 boreholes), casing depth is 28m(29 boreholes), production rate is 70 $m^3$/day and depth to water table of monitoring well is 23.26m, respectively. The geology of 60 wells can be divided into Daebo granite(20), Okchun metarmorphic complex(18), Precambrian granitic gneiss(15), Bulguksa granite(4), Cheju volcanics(2), Cretaceous sedimentary rock(1). Average electrical conductivity and pH are 152$\mu$S/cm, and 7.35, respectively. The contents of major cation and anion predominantly $Ca^{2+}$>N $a^{+}$>M $g^{2+}$> $K^{+}$ and HC $O_{3}$$^{－}$ >S $O_{4}$$^{2-}$>Cl￣>F￣. Water type is predominantly $Ca^{2+}$-HC $O_{3}$$^{－}$(81.7%). It's possible that water chemistry of some wells were affected not only by the geology of boreholes penetrated but by inflows of surface water or shallow ground-water. Therefore, it is strongly necessary to steadily monitor the water quality and hydrogeologic conditins of production wells.ells.ls.ells.

The reflectance of chlorophyll was measured using UV-VIS spectrophotometer with the reflectance integrator in the laboratory in order to define its spectral characteristics. Sharp peaks appear at around 485nm and 655nm due to fluorescence and scattering, and the reflectance of chlorophyll increases at 580nm. With the increase in the chlorophyll concentration, the reflectance also increases. We have applied TM data to the reflectance spectrum of chlorophyll and have developed two formula with which one can estimate the chlorophyll concetration. Satellite re sensing, with its synoptic overage, is used to obtain the chlorophyll concentration in Daecheong reservoir. The approach involved acquisition of water quality samples front boat simultaneous with Landsat 5 satellite overpass. The remotely-sensed data and the ground truth data were obtained oil 20 June 1995 and on 18 March 1996. Regression models have been developed between the chlorophyll concentration and Landsat Thematic Mapper digital data. As the regression model was determined based on the correlation coefficient which was higher than 0.7 and the spectral characteristics of chlorophyll, and we have applied it to the entire study area to genelate a distribution map of trophic state. According to the trophic state map made based upon Aizaki's TSI and chlorophyll a concentration, the area where Okchun stream was flowing into was shown to be polluted the most all over the Daechung reservoir by showing an eutrophic state in June 1995 and a mesotrophic state in March 1996.
