The purpose of this study was to determine whether abdominal pressure belt has an immediate effect on pulmonary function, balance and gait ability for stroke patients. Twenty subjects measured pulmonary function and the COP, BBS, TUG, 10m walk test, and FGA prior to belt wearing. Immediately all subjects were post-tested after wearing abdominal pressure belt of elastic components. Except for forced vital capacity (FVC) and forced experimental volume in the 1 second (FEV1), there were significant differences after belt wearing. This study suggests that the application of abdominal pressure belt enhanced balance and gait ability. However, improving pulmonary function requires several efforts, such as changing the pressure level, posture. 본 연구의 목적은 복부압박벨트가 뇌졸중 환자의 폐 기능, 균형 및 보행능력에 미치는 영향을 즉각적으로 알아보고자 함이다. 20명의 뇌졸중 환자를 대상으로 복부압박벨트 착용 전에 폐기능, 압력중심, 버그균형검사, 일어서서 걷기 검사, 10m 보행, 기능적 보행검사를 실시하였다. 복부압박벨트를 착용한 직후에 사후 평가를 실시하였다. 연구 결과 복부압박벨트를 착용하였을 때 노력성 폐활량과 1초간 노력성 날숨 유량을 제외한 모든 결과값이 유의한 변화를 보였다. 본 연구를 통해 뇌졸중 환자가 복부압박벨트를 착용하였을 때 균형과 보행 능력의 증가에 즉각적인 영향을 미친다는 것을 알 수 있었다. 향후 연구에서는 폐 기능을 개선시키기 위해 압박 수준과 자세 변경과 같은 노력이 필요할 것이다.

젖소가 사료를 먹는 양은 생리학적으로는 혈당과 포만감에 의해 조절되며, 일반적으로 국내에서 사용하는 사료섭취량은 미국 NRC(국립과학연구소, The National Research Council)에서 실험 통계학적으로 나온 결과를 기준으로 품종, 산차, 체중, 비유시기, BCS(체점수), 기온 등을 고려하여 설정되었다. 최근 우리나라에서 풀의 사용량이 갈수록 증가하고 있는데 이에 따른 수익도 있지만 문제점은 없는지, 특히 생리학적인 면에서 한번은 짚고 넘어가야 한다고 보기 때문에 필자가 언급코자 한다.
HL-60 세포에서 Myeloperoxidase 유전자 발현에 대한 All-Trans Retinoic Acid의 영향
임규,곽상태,황병두 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.1
Effects of all-trans retinoic acid on DNA synthesis and myeloperoxidase (MPO) gene expression have been investigated during the differentiation of human promyelocytic leukemia cell line HL-60. DNA synthesis was decreased at 24hr after exposure with retinoic acid. Conversely control (no adding retinoic acid) gradually increased DNA synthesis. The MPO mRNA was reduced at 24hr in retinoic acid-exposed HL-60 cells. The level of MPO mRNA was also reduced in proportion to the concentration of retinoic acid. MPO mRNA in the retinoic acid-exposed cells was constant after cycloheximide treatment. Retinoic acid-induced repression of MPO gene was no effect by staurosporin treatment. The results suggest that retinoic acid-induced repression of MPO gene is not related to phosphorylation by protein kinase C.

S-Adenosyl-L-methionine : protein-carboxyl 0-methyltransferase(prorein methylase II) has been purified from bovine skeletal muscle approximately 6,600-fold with a 7% yield by combination of ammonium sulfate precipitate, Sephadex G-75 chromatography, S-adenosyl-L-homocysteine-Sepharose 4B chromatography and hydroxyapatite chromatography, and then its characterizations and possible roles were investigated. The enzyme showed a optimum pH around 6.0. It was heat labile, inactivated by heat-treatment at 60℃ for 6 minutes, and when stored at -20℃ in the presence 10% glycerol, its activity has almost stabilized in 6 months. Copper ion(Cu^2+)and zinc ion(Zn^2+)were a potent inhibitors, the activity being completely inhibited at 0.25 mM and 1 mM respectively, The inhibition of copper and zinc ions were recovered 94%, 75% of its activity by adding 4 mM of EDTA, respectively. The apparent Km value for S-adenosyl--L-methionine was 2.86 x 10^-6 M. Kinetic analysis of enzyme in the presence of 30 uM copper ion showed that the nature of the inhibition to the enzyme was noncompetitive considering that Km was constant and Vmax was decreased. Histone IIA, immunoglobulin A and trypsin inhibitor were relatively good substrates for the enzyme. The enzyme activity was completely inhibited by 0.5 mM p-hydroxymercuribenzoic acid, but all of the activity was recovered in adding 10 mM mercaptoethanol, and the molecular weight of the enzyme was 24,000. Sarcolemma and sarcoplasmic reticulum of the skeletal muscle were good substrates for this enzyme and ^3H-CH_3 group was incorporated to 0.63 and 0.96 pmoles/mg protein/min, respectively. The carboxylmethylation of the sarcolemma of the skeletal muscle occurred in the 5 protein fractions(M. W. : 45,000, 22,000, below 14,400etc.) and that of sarcoplasmic reticulum occurred in the 7 protein fractions (M. W. : 100,000, 45,000, 22,000, below 14, 400 etc) by SDS/polyacrylamide gel electrophoresis. Among these molecular weight 22,000 was strongly methylated. These results discuss that protein methylase Il may play some roles in regulating physiological function of sarcolemma and sarcoplasmic reticulum of skeletal muscle.
