We evaluated the diagnostic usefulness of latexagglutination test for elevated serum myoglobin as a screening test in the early phase of acute myocardial infarction and 21 patients with chest pain mimicking acute myocardial infarction were included in this study. Result was compared with serum myoglobin level measured by radioimmunoassay (RIA) in every case. The Following results were obtained: 1) When serum myoglobin levels measured by RIA below 85ng/㎖ were regarded as normal, this test showed sensitivity of 82%, specificity of 95%. 2) In latex-agglutionation test for elevated serum myoglobin, test results were interpreted as negative, weakly positive and positive. If we regard weakly positive tests as positive, sensitivity was 93% and specificity was 62%. In contrast, if we regard weakly positive tests as negative specificity rose to 100% while sensitivity reduced to 75%. 3) Agreement rate of both test was k=0.59. It is suggested that latex-agglutination test for elevated serum myoglobin is helpful in ruling out acute myocardial infarction when test result is negative, and that it can be used as a screening test in the early phase of acute myocardial infarction because of its rapidity and simplicity in performing the procedure.

프로골프선수의 슬관절 등속성 근력에 관한 굴곡근과 신전근의 비교연구. 운동과학, 제 9권 제 1호. (201)-(209), 2000. 본 연구는 장기간의 골프운동이 슬관절의 단축성 굴근력과 신근력의 발달에 미치는 영향을 규명하여 경기력 향상을 위한 트레이닝 방법의 기초자료를 제공하고자 수행 되었다. 연구의 대상은 24명의 프로골프선수들(29.60±3.8세)로 골프경력은 12±1.7년으로 대상자 전원이 오른손을 주로 사용(우타)하였다. 측정은 등속성근력계(Cybex 770)를 이용하여 각속도 60°/sec와 180°/sec에서 3회씩 좌·우 교대로 측정하였다. 측정변인은 peak torque, peak torque 발현각, 평균파워, 총운동량 등이었다. 자료분석은 SPSS통계프로그램을 이용하여 실시하였으며 다음과 같은 결론을 얻었다.; 슬관절 굴곡근과 신장근의 좌·우 근력 비교에서 각속도 180°/sec로 굴곡성 운동시 총 운동량(total work)에서 좌·우측간에 유의한 차이가 있는 것으로 나타났으나(p<.05), 나머지 측정변인에서는 굴곡근과 신전근 모두 부하각속도에서 통계적으로 유의하지 않았다. 굴곡력의 경우 우측하지가 좌측하지에 비하여 높았으나 신전력의 경우 좌측하지가 다소 높은 경향을 보였다. 각 변인의 평균치에 대한 60°/sec와 180°/sec간의 비교에서는 모든 변인에서 통계적으로 유의한 차이를 나타내었다(p<.05). 슬관절 굴곡근의 신전근에 대한 비율(Flexor/Extensor Ratio)은 60°/sec에서 60%보다 낮게 나타났으나 좌·우측간 유의하지는 않았다. 결론적으로 다년간의 골프운동은 하지의 슬관절 근기능을 발달시키며 우측하지에 비해 좌측하지의 신전근에 더 많은 발달을 가져온다고 할 수 있다. A study on isokinetic concentric torque of kee extensor and flexor in golf players. Exercise Science, 9(1): 201-209, 2000. The purpose of this stydy was to investigate the effect of long therm golf exercise on isokinetic concentric torque of kee extensor and flexor. The subjects of this study were 24 men progolf players(29.60±3.8yrs) who have experience of 12±1.7yrs golf exercise and use mainly a right hand. The measurement was performed by use of Cybex 770 in angular velocity 60˚ /sec, 180˚ /sec and 3 repetitions. The variable of measure were peak torque, angle of peak torque, average power, total work and so on. The result of this study were as follow: There only was statistical difference between both low limb in Total work of knee flexor in angular velocity 180°/sec(p<.05) but not in other variables in both angular valocity. Right low limb was little stronger than reft low limb in flexor but there was opposite result in extensors. There was statistical difference between 60°/sec and 180°/sec in all varible. Knee flexors and extensors ratio was lower than 60% in angular velocity 60°/sec but there was no statistical difference between right and left low limb. It might be concluded from the test that long term golf exercise strengthen muscle function of knee flexors and extensor and left knee extensors more strengthen than right knee extensors.

In order to observe the aspects of prosthetic cardiac valve failure, we analyzed 26 cases of Redo operation among 1081 cases of valve replacemant performed from Jan. 1961. to July 1986. The results are as follows; 1) Crude Redo operation rate was 2.4%. 2) The most common cause or prosthetic cardiac valve failure was the primary tissue failure (73%) 8r the PVE was the 2nd (15.4%). 3) Mean valve implantation time was 47.7 months. Implantation time in the child group was shorter than in adult by 6.8 months, In the primary tissue failure group (19 cases) implantation time in the child was 42.8 months 8z in adult, 66.8 months. (P$lt;0.05) In conclusion, the durability of tissue valves was significantly decreased in the child age group because of increased propensity for calcification, so the preference of tissue valves especially in this age group should be reconsidered.

Rheomacrodex-D 10% W/V in dextrose (500 ml) was prophylactically infused before anesthesia over 15 to 20 minutes to prevent hypotension during spinal anesthesia in 20 patients undergoing elective Casarean section. Apgar scores and the incidence and severity of hypotension were compared to results obtained in 20 patients who were given 500 ml of Hartmann's solution. The results were as follows; 1) Mean arterial pressure decreased up to 20 torr from control values in patients hydrated with Hartman's solution and also changed significantly in patients given Rheomacrodex-D (p<0.05). 2) The incidence and severity of hypotension at 10 minutes, and 15 minutes, and 15 minutes after spinal anesthesia (p<0.05) was significantly less in patients given Rheomacrodex-D than in patients hydrated with Hartmann's solution 3) The Apgar scores, both at 1 minute and 5 minutes, were significantly higher (p<0.05, p<0.005) in infants born of mothers given Rheomacrodex-D than in infants whose mothers were given Hartmann's solution. 4) The cases of hypotension defined as a descrease in systolic arterial pressure lower than 100 torr or a decrease in mean arterial pressure to 25% from control values were 12 cases in 20 patients hydrated with Hartmann's solution and 6 cases in 20 patients given Rheomacrodex-D.

본 연구는 홀스타인 송아지에 대한 세 종류의 조사료가 유선조직, 반추위 유두, 번식성적 및 성장률에 미치는 영향을 조사하기 위하여 실시하였다. 출생 후 4일된 송아지(42.9±0.9㎏) 24두를 무작위로 선발하여 출생 후 4∼44일까지 전유를 급여하다가 45일에 그룹 1은 볏짚, 그룹 2는 오차드 그래스, 그룹 3은 알괄파를 급여하였다. 또한 유선조직과 반추위의 발달을 측정하기 위하여 3, 9, 18개월령에 도달하였을 때 각 처리구의 송아지를 1마리씩 도살하였다. 알팔파를 급여한 그룹 3은 다른 처리구에 비하여 중체율이 높았으며, 그룹 2는 영양소 이용률과 번식성적이 높은 경향을 나타내었다. 반추위의 무게는 3개월령 도달시에는 그룹 3이 가장 무거웠으나, 9개월과 18개월령 도달시에는 그룹 2에서 가장 무거운 것으로 나타났다. 반추위의 유두 수는 유두의 성장과 함께 일반적으로 감소하는 경향을 나타내어 유두의 길이와 유두 수와는 서로 상대적인 관계를 나타내었다. 유선의 기능적 활성을 나타내는 RNA/DNA 함량은 3개월 시에는 그룹 3이 가장 낮은 경향을 보였으나 9, 18개월 시에는 반대로 가장 높은 경향으로 나타났으며, 유선세포의 크기를 나타내는 protein/DNA 함량은 18개월 시에 그룹 2가 가장 높은 경향을 보였다. 결론적으로 본 연구에서 볏짚은 반추위의 초기 발달을 촉진하고 알팔파와 오차드그래스는 성장과 번식성적을 증가시키며 또한 초기에 유선의 발달을 촉진시키는 것으로 나타났다. Twenty-four Holstein calves were used to evaluate the effects of three different forages on growth and reproductive performances, and ruminal papillary and mammary developments. Four-day-old Holstein calves weighing 42.9±0.9 ㎏ were randomly assigned to three forage groups of rice straw (group 1), orchard grass hay (group 2), and alfalfa (group 3). All calves received whole milk from day 4 through day 44. At 45 days of age, the animals were assigned at random to one of the three dietary treatments. When calves reached the ages of 3, 9, and 18 months, one calf in each group was sacrifced for evaluation of ruminal and mammary tissue developments. Calves of group 3 gained more body weight than those of other groups, while group 2 showed an effective nutrient utilization and reproduction performance. At 3 months, the stomach weight of group 3 was the highest, however, group 2 provided the highest stomach weight at 9 and 18 months. A remarkable reduction in papillae number was observed in the rumens of all 3- to 9-month-old heifers. A decrease in number of these papillae was observed in all groups exhibiting papillary growth. There was a reciprocal relationship between the number and the length of ruminal papillae. Among the 3-month-old calves, the functional activity (RNAI DNA contents) of the mammary glands of group 3 was lower than those of other groups, whereas the trend was opposite for 9- and 18-month-old heifers. The size of mammary cell (protein / DNA contents) was the greatest for group 2 at 18 months of age. The results suggest that rice straw stimulated earlier development of rumen. Alfalfa and orchard grass improved the growth, reproduction performance, and earlier development of mammary glands.

Midazolam maleate, a water soluble banzodiazepine unlike diazepam, was synthetized by Walser and Fryer in 1975. In order to ealuate the effectiveness as an induction agent for general anesthesia, 22 elective surgical patients belonging to ASA classification 1 and 2 were selected. And ten patients (male 7, female 3, average 33.5 years old) were induced with midazolam maleate 0.2mg/kg and twelve patients (mdale 7, female 5, average 32.5 years old) with diazepam 0.3mg/kg. The results were summarized as follows. 1) Anesthesia was induced in all of midazolam group by one intravenous injection, but only 6 patients of diazepam group could induced by one injection and the other 6 patients needed 2 or more injections. 2) The changes of blood pressure and pulse rate after induction and intubation were almost similar in the two groups, but greater individual variation was seen in diazepam group. 3) A buring sensation following intravenous injection was noted in 11 cases of diazepam group, but none in midazolam group and no phlebitis in either group. From the above results, diazepam and midazolam are almost similar in nature but midazolam is definitely effective as an induction agent and has less side effects. Therefore midazolam maleate is regarded as a more effective agent than diazepam as an induction for general anesthesia.
