Objectives & Methods : This study was to study etiology and pathologic mechanism and to study acupuncture and moxibustion treatment for GU-CHANG. I've got compared and analyzed 42 kinds of book since Nei Jing(內經). Results and Conclusion : 1. The etiologies are heat of heart and spleen, insufficiency of middle -warm energy, deficiency of yin lead to hyperactivity of fire. 2. The meridians of acupuncture points which were used much for GU-CHANG were Conception Vessel Meridian, Stomach Meridian and Bladder Meridian. 3. The frequency of using acupunture points in this treatment were Hapkok(LI4)-17th, Sungjang(CV24)-14th, Nogung(P8)-12th, Kumjin Okaeg(NH70)-11th.

For the production of poly(3-hydroxybutyrate-co-3-hydroxyvalerate)(P(3HB-co-3HV)) from butyric acid and valeric acid, 10 strains of bacteria capable of producing P(3HB-co-3HV) were isolated from soil. Among them, the strain HJ-067 showed the best ability of producing P(3HB-co-3HV), and was indentified as a Azotobacter sp. For the production of P(3HB-co-3HV), the optimum concentrations of butyric and valeric acid were 3.0g/l, respectively. The most effective nitrogen source was $(NH_4)_{2}SO_4$ at an optimum concentration of 0.75g/l, which was equivalent to 21.36 in C/N ratio. Deficiency of the cationic metal ions ($Zn^{2+},\;Co^{2+},\;Mn^{2+}$) in the proguction medium had stimulating effect on P(3HB-co-3HV) accumulation, especially in the manganese. deficient medium. The optimum temperature for P(3HB-co-3HV) production was 27$^{\circ}C$ and the optimum initial pH was 7.0. Under the optimum conditions, 1.82g/l of P(3HB-co-3HV) and 3.00g/l of dry biomass were produced after 36 hour cultivation, and the P(3HB-co-3HV) yield and HV% were 60.60% (w/w), 15.92%, respectively.
