Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).

이범재,권영배,김태동 안동대학교 환경연구소 2001 환경연구 Vol.1 No.-

In treatment of hazardous wastes like fly ash, landfill has been generally the most economical and easy method of treating this waste in Korea. But there is a stringent restriction on landfill because soil and groundwater contamination is occurred by the leachate from landfill materials. Modified stabilization/solidification technology, to solve these problems in landfill and melting processes, is researched with which we can stabilize heavy metals in solidified matrix. Objectives of this study are development of S/S process technology for stabilization of pollutants in hazardous wastes, and determination of the optimum additives and their mixing ratio for increasing the physical propriety of solidified matrix and reducing the pollutants leaching concentrations. The results of this study are as follows; Solidified matrix' proprieties such as heavy metals leaching concentrations and compressive strength were improved when slag and rice husk ash were used such as pozzolan materials and added additives as sorts of aluminate, sulfate and silicate chemicals. In the case of HS fly ash, when 5% sodium silicate and 10% cement were used as additives, compressive strength was over 90 kgf/㎠ in 28 the curing days and when sodium silicate and slag were added, heavy metal leaching concentrations were under the criteria in the 7 curing day. In the case of KM fly ash, the physico-chemical proprieties (compressive strength of solidified matrix and heavy metal leaching concentrations) were improved over 150 kgf/㎠ in 28 curing days by the additives like slag and rice husk ash (pozzolan materials) and sorts of aluminate, sulfate, silicate, etc.

이범모,한세현,김관식,정동균 대한구강생물학회 1990 International Journal of Oral Biology Vol.14 No.1

Formaldehyde that is active constituent in formocresol used in pulpotomy is known as toxic agent that causes systemic toxicity. To determine the fate of the ^14C-formaldehyde which was absorbed following its application to pulpotomy sites, by-pass of posterior facial vein and cannulation of external carotid artery were established with 20G-polyethylene tube. Blood samples (0.2ml) were collected in glass syringe before the pulpotomy and then at 0, 3, 5, 10, 20, 30, 45, 60, 90 and 120 minutes thereafter. Plasma was separated after centrifugation at 3000 x g for 15 min and aliquots of plasma were counted by liquid scintillation counter. After liver, kidney, lung ,heart, spleen, muscle, and alveolar socket were removed and solubilized with tissue solubilizer, the radioactivities in solutions were counted by liquid scintillation counter. The acute toxicity of formocresol was determined by BUN, GOT and OCT assay in blood samples collected 0, 2, 4, 6, 9 and 12 hours by means of cardiac puncture. The results were as follows ; 1. The radioactivity of ^14C-formaldehyde reached maximal value at 3-5 minutes and decreased thereafter. 2. About 8% of ^14C-formaldehyde placed in the pulpotomy site was actually absorbed systemically until 2 hours. 3. About 50% of ^14C-formaldehyde absorbed actually was distributed within 20 minutes. 4. The radioactivity of organ per gram was highest in the spleen and lowest in the muscle. 5. Total radioactivity of organ was highest in the liver and lowest in the heart. 6. There were no significant differences between control and experimental groups in BUN, GOT and OCT assay.
