[Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.

본 연구에서는 측정 방법이 다른 두 전리함을 이용하여 고선량율 근접치료용 방사성 선원의 겉보기 활성도를 측정하여 선원의 활성도 정확성 및 두 장비간의 정확도를 비교 분석하였다. 국내 5개 의료기관을 선정하여 공기 중 기준거리에서 겉보기 활성도를 측정하고 동일한 선원에 대하여 측정 방법이 다른 두 팬톰을 동시에 측정하여 측정방법에 따른 상호 오차와 측정용 전리함의 정확도를 평가하였다. 우물형 전리함과 Jig 팬톰의 상대 오차는 각각 -2.1%~0.2%, -2.8%~-1.0%로 나타났다. 동일한 방사성선원에 대하여 두 교정 장비간의 정확도 평가는 최대 상대오차 1%로 나타났다. 선원의 세기 검증 시 측정 방법에 따른 의존도는 없었다. 고 선량율 근접방사선치료에 사용되는 방사성 선원의 세기의 변화는 환자의 종양 및 인접장기에 미치는 영향이 매우 크므로 방사성 선원의 세기 오차는 환자치료의 최적화에 심각한 영향을 미칠 수 있다. 그러므로 새로운 선원 교체 시 뿐만 아니라 주기적인 선원 점검이 요구된다.

건천마와 발효천마의 추출물을 이용하여 항노화 활성과 신경성장인자 유도효과를 비교하였다. 항산화 활성을 비교하여 측정한 결과 모든 추출물에서 비교적 높은 항산화력을 나타내었으며, 발효하지 않은 건천마 추출물보다 발효과정을 거친 발효천마 추출물에서 다소 높은 항산화력을 나타내었다. Angiotensin converting enzyme(ACE)와 xanthine oxidase(XOase) 저해 활성을 측정한 결과 DW 추출에서 DPPH가 건천마 $64.14{\pm}0.89%$, 발효천마 $66.21{\pm}1.03%$으로 나타났고, ABTS가 건천마 $54.15{\pm}1.37%$, 발효천마 $60.24{\pm}2.25%$로 나타났다. 70% EtOH추출에서도 유사한 결과를 보여 발효천마 추출물이 ACE에 대해 높은 저해활성을 나타내었으나, XOase에 대하여 발효 및 건천마 추출물의 차이는 크지 않다는 것을 알 수 있다. 그리고 nerve growth factor (NGF) 활성 측정 결과 모든 추출물에서 40%의 신경돌기 성장효과를 나타내었다. 이와 같이 건천마와 발효천마의 추출물을 상대로 천마의 항노화 활성과 신경성장인자 유도효과에 대한 기능성을 탐색한 결과 발효천마가 건천마보다 우수한 생리기능성을 가지는 것을 알 수 있어, 발효과정을 통하면 천마의 활용도를 높일 수 있다는 것을 증명할 수 있었다.

Mitral and aortic valve replacement with tricuspid annuloplasty was undertaken in 5 patients out of 38 valvular surgery between the period from Jan. 1977 to May 1979 in the Dept. of Thoracic and Cardiovascular Surgery in Korea University Hospital. All were male patients with age ranging from 18 to 42 years, and preoperative evaluation revealed one case in Class IV, and four cases in Class III according to the classification of NYHA. Preoperative diagnosis was confirmed by routine cardiac study including retrograde aorto- and left ventriculography, and there were two cases with MSi+ASi+Ti, two cases with MSi+Ai+Ti, and one case with Mi+Ai+Ti. Double valve replacement was performed under the hypothermic cardiopulmonary bypass with total pump time of 247 min. in average ranging from 206 min. to 268 min. During aortic valve replacement, left coronary perfusion was done in the first two cases, and cardiac arrest with cardioplegic solution proposed by Bretschneider was applied in the remained three cases. Starr-Edwards, Bjork-Shiley prosthetic valves and Carpentier-Edwards tissue valve were replaced in the aortic area, and Carpentier-Edwards and Angell-Shiley tissue valves were replaced in the mitral area with each individual combination [three prosthetic and two tissue valves in the aortic, and five tissue valves in the mitral area respectively]. Postoperative recovery was uneventful in all cases except one case with hemopericardium, which was managed with pericardiectomy on the postoperative 10th day in good result. Follow-up after double valve replacement of the all five cases for the period from 6 months to 33 months revealed satisfactory adaptation in social activity and occupation with cardiac function of Class I according to the classification of NYHA In all five cases.

Purposes： The purposes of this study were to investigate the smoking cessation counselling activities among community health practitioners(CHP) and to identify the predictors of their smoking cessation counselling activities. Method： A descriptive-correlation study using self-administered questionnaires was conducted. Questionnaires were mailed to all the CHP in a community. A total of 330 CHPs participated in this survey. Results： Of the CHPs surveyed, 245(74.2％) returned completed questionnaires. Most CHPs(90.7％) believed that if a health professional advises their patient to quit, the patient's chances of quitting smoking are increased. While the majority of CHPs “asked, advised, and assessed” their clients, a minority of CHPs “assisted, arranged, and recorded”. In the final stepwise multiple regression model, attitude about smoking cessation policies and counselling activities, self-efficacy of smoking cessation counselling knowledge and skills, and perceived barriers of smoking cessation counselling activities were identified as significant predictors of smoking cessation counselling activities among CHPs. Conclusion： Smoking cessation counselling activities are not a routine part of CHP practice. Efforts should be made to increase the self-efficacy of smoking cessation counselling knowledge and skills among CHPs. Helping CHPs to overcome their barriers to smoking counselling may open up new channels for smoking intervention.
