        체형에 따른 골프 어드레스 동작의 주요 관절각도 비교

        최민철,이창진,임영태 한국운동역학회 2011 한국운동역학회지 Vol.20 No.4

        This study was aimed at comparing selected joint angles at the golf address stance by categorizing three different body types. 43elite male golfers were selected and 9 of them turned out to be the ectoderm while 24 of them to be the mesoderm. The remaining 10 subjects were the endoderm. The measurement was carried out at the address stance with the number 7 iron and the driver. The result showed that the angle of trunk flexion did not different among body types. The trunk tilting angle became more inclined to the right side, which confirmed the guidelines from most of golf lesson books, for bigger people since they tended to put more weight on the right foot. The angle of both knees showed similar but the right knee was bent more than the left knee. The target direction and body alignment faced more to the left side than the target spot because of the influence of open stance and natural aiming position. It seems that pelvis and knees turned a little bit more to the right side than the target direction in order to maintain the parallel. Overall, significant differences among body types were found at the trunk tilting angle and pelvis-target alignment and golf address configuration can be differentiate by these factors.

        침술자극이 개의 위 배출시간에 미치는 영향에 관한 X선 및 초음파학적인 평가

        최민철,장진화,이기창,남치주,양일석,윤여성,윤정희 한국임상수의학회 2003 한국임상수의학회지 Vol.20 No.1

        This study was performed to evaluate the effect of acupuncture on gastric motility in dogs with radiography and ultrasonography. All experimental dogs were fed with the soup with barium (3% W/V), and thereafter gastric emptying time(GET) was measured with radiography and ultrasonography with Bolondi's method. The acupoints were CV-12, PC-6, ST-36 and BL-21 in this experiment. On these acupoints, electroacupunctral stimulation(15MHz, continous wave) was applied for 20 minutes. The results were as follows: In the control group, normal GET was 70-85 minutes with ultrasonography, and 110-130 minutes with radiography. In acupuncture stimulation groups, there was no effect of gastric motility in CV-12, PC-6, and ST-36, whereas there was significant stimulating effect of gastric movement in BL-21 with ultrasonography (P<0.05) and radiography (P<0.01). Above these results, it is concluded that acupunctural stimulation of BL-21 was more effective in gastric motility compared to those of CV-12, PC-6 and ST-36.

        Comet assay slides 에서 나타난 apoptosis 평가에서 함수 및 탈수 겔의 비교

        최민철,수즌엠러루,에드워드엘질럿 한국임상수의학회 1996 한국임상수의학회지 Vol.13 No.2

        Comet assay 는 포유류 세포에서 DNA의 파괴를 측정하는데 있어 신속하고 단순하며 시각적이고 민감한 방법이다. Apoptosis에서는 세포핵의 광범위한 DNA의 붕괴가 일어나므로 comet assay는 종양세포에서 apoptosis가 발생되었는가를 알아내는데 유용하다. 본 연구는 apoptosis 연구의 결과가 변화되지 않도록 comet assay slides를 좀 더 오래 보관할 수 있는 방법을 개발하고자 시행되었다. 개의 종양세포를 가지고 alkali comet assay를 끝낸 뒤 slides를 진공 건조기에서 꺼내서 증류수로 점적하여 10-20분간 침수시키고 현광현미경하에서 육안적으로 관찰하였다. 건조후 3-4일, 1주, 2주, 3주, 4주 및 7주의 slides에서 apoptosis 회복율(%)은 각각 98.1, 98.3, 99.4, 80.8 및 35.2%이었다. 3주 이내의 slides에서 대조군과 비교하여 apoptosis 회복율에서 차이가 없었으나 4주 이상의 slides를 건조후 침수시키는 방법을 이용하였을 때 apoptosis 평가에서 건조 후 3주간까지는 처음의 결과와 차이가 없으며, 이 방법을 이용하여 comet slide의 좀 더 긴 기간이 보관과 보관후의 재평가에서 이용될 수 있는 좋은 방법이 된다.

        동물(젖소)건강 Monitoring system 모델 개발 V. 임상학적 위해요소 분석

        최민철,김종수,김곤섭,김용환,이효종,손우진,원현희 한국임상수의학회 1999 한국임상수의학회지 Vol.16 No.2

        An animal health monitoring system in Gyeongnam area (near-Chinju) was studied to evaluate the environmental risk factors, physical examinations and 4 disease entities(abomasal displacement, traumatic reticulopericarditis & -peritonitis, milk fever and lameness) in 40(34 in second year)dairy herds (total 1253 dairy cattle). In feeding environments, we examined housing system, forage percentage in ration, stall types, playground, cleanness of stall. In housing system, most of herds (60%) have tie-stall types and 36 herds are open-type housing. The forage ratio of ration was less than 50% in most of herds (67%). 39 herds had their own playgrounds and the frequency of playground cleanness was irregular, Physical examinations included the T(temperature), P (pulse), R (respiration), abnormalities of superficial lymph nodes, claw examination and total CBC with blood from tail veins. T, P, R are within normal limits (T : 38.1$\pm$0.6$^{\circ}C$, P : 84.6$\pm$12.9/min., R : 24.0$\pm$7.6/min. ,respectively), the swelling of lymph nodes were shown in 13 cattle and overall claw trimming was required in 3 herds. In blood examination, 23 cattle showed leuko-cytosis and 7 cattle showed low RBC and hemoglobin level, the other cattle were within normal limits (WBC : 8.90$\pm$2.06 10$^3$/ul., RBC : 6.36$\pm$1.02 10$^{6}$ ul, Hb : 9.83$\pm$ 1.20 g/dl PCV : 27.43$\pm$5.67 %, respectively). In 4 disease entities, we found some metallic foreign bodies in men of 13 cattle, which had predisposing factors of traumatic reticulopericarditis and reticuloperitonitis, 13 abomasal displacement, 51 milk fever and lameness in 39 cattle.

        최민철,김진구,김태원,김용환,신종욱,원현희,이은주 한국임상수의학회 1999 한국임상수의학회지 Vol.16 No.1

        A 4-year old male Pitbull terrier dog was presented with a history of nasal discharge of left side and dyspnea for 3 days. This dog had a bitewound on the head due to dog-fighting two weeks ago. There was no abnomality except mild anemic sign on blood examination. Frontal projection of radiographs was taken. This was diagnosed as frontal sinusitis. After skin incision on frontal head, a silicone tube was inserted into the affected frontal sinus. Abscess of the frontal sinus was drainaged and irrigated with saline solution containing trypsin and cephazolin. This patient who also treated with enrofloxacin was recovered completely.

        쥐에서 Carboxymethylcellulose 및 Ibuprofen을 이용한 유착형성 방지에 관한 연구

        최민철,이효종,김곤섭,Choi Min-Cheol,Lee Hyo-Jong,Kim Gon-Sup 한국임상수의학회 1993 한국임상수의학회지 Vol.10 No.2

        With the use of a rat surgical model, the ability of carboxymethylcellulose and ibuprofen in the reduction of abdominal adhesion was examined. Seventy seven female rats were randomly divided into 7 groups : (1) control, (2) 2% CMC, (3) 3% CMC, (4) ibuprofen 25mg, (5) ibuprofen 50mg, (6) combination of ibuprofen 25mg and 2% CMC and(7) combination of ibuprofen 50mg and 3%, CMC. Following induction of abrasion injuries on ileum, colon and both uterine horns with a surgical blads, the rats in groups (2), (6) were infused with 2% CMC solution singly or in combined Infection of 25 mg/kg of ibuprofen for three consecutive days, the rats In groups (3), (7) were infused with 3% CMC solution singly or In combined Injection of 50mg/kg of ibuprofen for three consecutive days. The rats in groups (4), (5) were injected only with 25 mg or 50 mg/kg of ibuprofen for three consecutive days. After 10 days the abdominal cavities were opened and the appearance of formed adhesion were graded. The changes of body weight, CBC and blood chemicals were also evaluated at 3, 6 and 10 days after operation. In ileum, the rats in the groups (2), (6) and (7) showed less adhesion formation. In colon, there were significant differences(p<0.05) in adhesion formation in all treated groups as compared to control. In both uterine horns, there were significant decrease(p<0.05) of adhesion formation in groups(2), (6) and (7) in comparison with other groups. The increasing rate of body weight was evident in group (3) and fibrinogen concentrations at 6 and 10 days revealed significant decrease (p<0.01) in group (7), whereas there was no consistent change in CBC and blood chemicals. Therefore, it can be sugested that the infusion of 2% CMC solution with or without the injection of 25 mg/kg of ibuprofen and 3% CMC solution with the injection of 50 mg/kg of ibuprofen are effective and safe following abdominal surgery,
