This study was conducted to determine whether low intensity regular exercise following steroid treatment could attenuate steroid-induced muscle atrophy. Thirty-eight Sprague-Dawley rats weighing 165~175g were divided into six groups;control group(C), dexamethasone administration group(D), sedentary after normal saline administration group(C+Se), exercise after normal saline administration group(C+Ex), sedentary group after dexamethasone administration(D+Se), exercise group after dexamethasone administration(D+Ex). Either dexamethasone(5mg/kg) or normal saline was injected for 7days accordingly. Exercise was started at 10m/min on the 10?grade treadmill and gradually increased up to 15m/min by the 7th day for 60minutes/day(20min×3). The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSS WIN 9.0 program. Body weight, muscle weight and myofibrillar protein content of both plantaris and gastrocnemius, Type I, II muscle fiber cross-sectional area of plantaris, and Type II muscle fiber cross-sectional area of gastrocnemis in D group were significantly lower than those of C group(p<.05) respectively. Hindlimb muscle weight, myofibrillar protein content of both plantaris and gastrocnemius, Type I muscle fiber cross-sectional area of soleus and Type I, II muscle fiber cross-sectional area of plantaris in D+Ex group tended to increase compared to those of D+Se group. Myofibrillar protein content of both plantaris and gastrocnemius, Type I muscle fiber cross-sectional area of plantaris in D+Ex group tended to increase compared to those of C+Se group. Based on these results, it is suggested that regular low-intensity exercise during recovery period after steroid treatment might facilitate the recovery from steroid-induced muscle atrophy.

정명순,박홍성 강원대학교 산업기술연구소 2003 産業技術硏究 Vol.23 No.A

Because the quality of a radio link in real environment is generally varied with time, there is a difference between the delay in the real environment and one obtained from the analytic model where a time-varying link model is not used as a link model for a Bluetooth This paper analyzes the transmission delay of a message in the time-varying radio link model for the Bluetooth. The time-varying radio link is modeled with a two-state Markov model. The mean transmission delay of the message is analytically obtained in terms of the arrival rate of the message. the state transition probability in the Markov model. and the packet error rate.

A diagnosis program of damage-symptom caused by fruit tree pest was developed using Portable Document Format (Docucom PDF). To construct program structure, the damage patterns of plants cased by pests and the morphological rhararteristics of pests were sorted by plant organs. Diagnoses are rallied out by selecting a host species > document symptoms arranged by plant organs > comparing similar symptoms of pests using step by step menu through damage symptoms. In addition, pest information can be accessed either through the scientific or common name of the pest organism.

The cytotoxicity of carboxyethylgermanium sesquioxide(Ge-132) and anticancer drugs (cisplatin, mitomycin C, 5-fluorouracil) against tumor cell lines(L1210, SK-HepG-1) and mouse splenocytes was examined by MTT assay. Ge-132(8.5 x 10²㎕/ml, 1.7 X 10³㎕/ml, 3.4 x 10³㎕/ml) showed dose-dependent cytotoxicity against the tumor cell lines, on the contrary, increased cell proliferation against the normal mouse splenocytes. Combination of Ge- 132 with cisplatin(1.5㎕/ml, 15㎕/ml), mitomycin C(0.5㎕/ml, 1.0㎕/ml) or 5-fluorouracil (0.31㎕/ml, 1.25㎕/ml) showed additional cytotoxicity against L1210 and SK-HepG-1 cell lines, however, reduced clearly the anticancer drugs-induced cytotoxicity against the normal mouse splenocytes.

민순홍,표명윤 숙명여자대학교 약학연구소 2006 약학논문집-숙명여자대학교 Vol.23 No.-

We investigated the cytotoxicity of chitosan on cancer cell lines (P388, L1210, HCT-15, and SK-HepG-1) and mouse splenocytes as normal cells by MTT assay. Chitosan (37.5㎍/㎖, 75㎍/㎖, 112.5 ㎍/㎖, and 150㎍/㎖) showed dose-dependent cytotoxicity against the cancer cell lines. Particularly, chitosan showed lower cytotoxicity against the normal mouse splenocytes than against the cancer cell lines at high doses (112.5㎍/㎖ and 150㎍/㎖). These results indicate that chitosan may selectively induce growth inhibition in cancer cell lines.

대구 지하철 참사 이후 사회 전반적으로 방염에 대한 관심이 증대되어 방염제에 대한 연구가 활발하게 진행되고 있는 실정이다. 기존의 할로겐화 방염제는 방염제 자체의 독성으로 인해 인간의 건강과 환경에 유해성이 확인됨에 따라 이를 대체할 친환경 방염제의 연구가 부각되고 있는 시점이다. 본 연구에서는 친환경 대체 방염제의 일환으로 인계와 무기계 방염제를 혼합 사용하여 우수한 방염성능 및 연소시 유독가스가 발생되지 않는 친환경 방염제의 조성을 설계하고자 하였다. 인계 방염제로서 제1인산암모늄, 제2인산암모늄을 사용하였으며, 무기계 방염제로서 붕산과 붕사를 사용하여 각 조성 배합비의 함량 변화 실험을 통한 방염 특성 평가를 수행하였다. 이와 더불어 방염제의 부착률에 따라서 방염효과가 달라지는데, 최적의 조성으로 부착률을 달리하여 경제성과 법적인 측면을 고려하여 가장 효율적인 부착률을 알아보았다. The purpose of this research is to make a non toxic flame retardants as a substitute material for toxic halogen type, and to evaluate burning area, adhesion rate and flammability of non toxic flame retardants. The non toxic flame retardants were prepared by mixing processes of ammonium phosphate monobasic, ammonium phosphate dibasic, boric acid and borax under the various preparation conditions. Flammability of polyester fabrics treated with these mixed flame retardants was investigated through measurement of burning area and adhesion rate. The burning area values were decreased with increase of the Ammonium phosphate monobasic and ammonium phosphate dibasic content of flame retardants. For economic and legal reasons, the optimum adhesion rate of flame retardants on the polyester fabrics was 50%.

There have been many trials of clinical efficacy of multicomponent and single component treatments for irritable bowel syndrome(IBS). We reviewed effects of non phamacological treatments in the IBS. Though the efficacy of multi-component approaches was unclear, several results suggest that cognitive behavioral therapy was effective in improving gastrointestinal symptoms of IBS. As a single component, cognitive therapy and relaxation with or without biofeedback could improve the symptoms and psychological health of IBS patients. Yoga, meditation, self-help information and hypnotherapy could be applicable to IBS.
