In this report, we present a case of the male pseudohermaphrodite in a beagle dog. The animal was subjected for examination due to enlargement of clitoris that was shown as reddish finger-like structure protruding from the vulva. Visual examination of the internal genitalia revealed that the animal possessed both testes and uterus. Based on the findings of physical examination and exploratory laparotomy, it was tentatively diagnosed as male pseudohermaphrodite. Internal genitalia and enlarged clitoris were removed for the prevention of pyometra and Sertoli cell tumor.

Effects of Jeongkicheonhyangtang and Kamijeongkicheonhyangtang have been experimentally studies. The results have been obtained as follows: 1. It is proved that analgecic effect on sample I group and sample II group are clearly decreased than control group. Thus, the statistically significant decrease is p<0.005. 2. It is proved that anti-inflammatory effect on sample I group and sample II group are decreased compare to control group. Thus, the statistically significant decrease of sample I group is p<0.05 in 30 and 60-minute, p<0.01 in 90-minute, and p<0.005 in 12 and p<0.005 in 90, 120 and 180-minute. 3. It is proved that appearance of gastric ucler is decreased compare to the control group and the statistically significant decrease is p<0.05. 4. It is proved that plasma epinephrine contents of sample I and II group are clearly decreased compare to the Control Group and the statistically significant decrease is p<0.005 5. It is proved that plasma norepinephrine contents of sample I group is drastically decreased compare to the control group and the statistically significant decrease is p<0.005. 6. It is proved that plasma dopamine contents of sample I and II group are decreased than the control group and statistically significant decrease of the sample I group is p<0.005, and those of the sample II group is p<0.05. As the above mentioned results of experiment, it is believed that Jeongkichenhyang and Kamijeongkicheonhyang have effect for stress.

The purpose of this study is to elucidate the effects of regular swimming exercise on blood lipoprotein metabolism and leptin. In this study, swimming(HRmax 50-75%, 60min/day, 5day/week) was performed and 18 were participated for study during 16 weeks. They were divided into two groups, one group as experimental group(n=9) and the other as control group(n=9). A measured factors were TC, TG, HDL-C, LDL-C and leptin.. All data were expressed as mean± standard deviation by using spss package program(win 9.0), one way anova and independent t-test was used to analyze the difference of exercise duration(0week, 8week, 12week, 16week) between groups. For all statistics performed statistical significance was set at p<.05. After exercise intervention, TC, TG, HDL-C, LDL-C and leptin were found to have more significant effects in the experimental group than control group. This results indicated regular swimming exercise training is beneficial to prevent and treat cardiovascular disease and obesity.

The present study investigates the spray characteristics of water mist nozzle with mid-low pressure for fire suppression. The examined nozzle types are swirl nozzle. The result shows that K factor of water mist nozzle is much smaller than those of general sprinkler. Spray angle of spiral nozzle is largest and more than 150˚. SND(Sauter Mean Diameter) of water mist nozzles is ranged between 100 and 200㎛ through measuring by image processing method. The spray pattern of spiral nozzle represent that water flux of first stream is 2 times larger than that of second stream. This study will contribute better understandings of the water-mist spray characteristics and useful data for developing the water-mist nozzles.

아데노이드 및 구개편도 절제술이 비저항과 비강 내 Geometry에 미치는 영향

나기상,박찬희,구본석,김영덕,김관호,박용호 충남대학교 의학연구소 2003 충남의대잡지 Vol.30 No.2

수술 전 최소단면적이나 비강 부피는 아데노이드나 구개편도의 비대 정도와 상관관계를 보이지 않았으나 비저항은 아데노이드 비대 정도와 유의한 상관관계를 보였다. 구개편도 및 아데노이드 절제술 후 코막힘과 구호흡 증상의 유의한 호전을 보였다. 수술 후 비강의 최소단면적과 부피 등 nasal geometry는 통계적으로 유의한 변화가 없었으나 비저항은 수술 후 유의한 감소를 보였으며 수술 후 비저항의 감소 정도는 아데노이드 비대 정도와 유의한 상관 관계를 보였다 . 이상의 결과로 아데노이드와 구개편도의 비대를 보이는 소아에서 코막힘 증상을 일으키는 데는 아데노이드 비대가 주요 원인이 되며 주로 비강의 후방에 위치한 아데노이드의 mass effect에 의할 것으로 생각한다. The aim of this study was to determine whether adenoid or tonsillar hypertrophy and subsequent adenoidectomy and tonsillectomy affect pediatric nasal airway resistance and nasal geometry and to evaluate the relationships between the degree of hypertrophy and nasal airway resistance or nasal geometry. Thirty-two children, aged 3 to 15 years, selected for adenoidectomy and tonsillectomy due to chronic nasal obstruction and mouth breathing were enrolled. The size of adenoid was evaluated by cephalometric radiograph. The degree of tonsillar hypertrophy was graded clinically. Nasal airway resistance and nasal geometry was evaluated by active anterior rhinomanometry and acoustic rhinometry respectively. These measurements were repeated one month and three months post-operatively. The size of adenoid was found well correlated to preoperative nasal airway resistance. However, there were no correlations between the degree of tonsillar hypertrophy and preoperative nasal airway resistance or nasal geometry. Nasal geometry was not changed after operation. However, nasal airway resistance was reduced significantly at 3 months after operation and the size of adenoid was found well correlated to postoperative changes of nasal airway resistance.

後前의 Bacillus subtilis 菌에 의한 大麻皮의 纖維精練 方法을 改善하기 위해 Erwinia carotovora subsp. carotovora(植物 軟腐 病原菌)의 生育 培地別, 培地 pH別, 處理溫度別 및 處理時間別 pectin의 分解率과 現地 工場에서의 實用實驗의 精練程度 및 pectin 分解率에 基礎한 새로운 精練方法을 開發하였다. 1. 大麻皮 精練을 위한 E. carotovora의 利用에 있어서 母液培地로는 Nutrient broth나 0.5% pepton水보다는 最少無機염類培地가 pectin分解率에 있어서 가장 높았고 B. subtilis보다 pectin分解 活性이 훨씬 높았다. 2. Pectin分解率이 가장 높았던 E. carotovora 母液培地(最少無機염類培地)의 pH는 7.0에서 부터 8.0 사이였다. 3. E. carotovora를 利用한 大麻皮 精練 處理溫度는 30~35℃, 處理時間은 24~36時間이 合理的이었다. 4. 生産工場에서 實用試驗의 結果 B. subtilis 보다 E. carotovora가 精練效果에 있어서 越等히 좋았고, 1次 處理完了液을 그대로 2次 處理에 利用할 수 있었으며 보다 精練效率이 좋았다. 5. 以上의 結果에서 E. carotovora를 利用한 大麻皮 精練의 새로운 方法을 提示하면 다음과 같다. 菌母液으로는 最少無機염類培地(pH 7.0~8.0)를 利用하고 精練條件으로는 處理溫度 30℃, 處理時間 24~35時間, 連續 2回 處理하며, 强制합氣는 不必要하나 廢液의 滅菌處理가 必要하다. Fermentation conditions for the hemp refining by an anaerobic bacterium, Erwinia carotovora subsp. carotovora, were investigated. Percentage of the hemp pectin decomposition(% HPD) by the bacteria grown in the minimal broth, was measured as a indicator of fermentation since the % HPD was higher in the minimal broth than in the nutrient broth or 0.5% pepton water. The Optimal pH and temperature for the % HPD were pH 7.0~8.0 and 30~35℃, respectively. Fermentor test a factory demonstrated that E. carotovora is more effective organism than B. subtilis, which has been used up to now, for hemp refining at least in the condition of using minimal broth.

소아 갈색세표종 적출술 마취경험 1례

김영진,송찬우,김정원,신동엽,홍기혁 인제대학교 1995 仁濟醫學 Vol.16 No.3

소아에서 흔하지 않은 갈색세포종의 적출술을 위한 마취를 성공적으로 시행하였기에 보고하고자 한다. An one anesthetic experience with right adrenalectomy for phochromocytoma in a 13-year-old children has been reported. Thiopenthal sodium 174mg and succinylcholine 40mg were used for endotrachal intubation, followed by N2O, O2, and isoflurane for induction and maintenance. During anesthesia and operation, the highest systolic blood pressure was 210mmHg, the lowest was 130mmHg, and some variable arrhythmias were present. But these were well controlled immediately after administration of labetalol and propranolol. The patient tolerated anesthesia and surgery well, despite the episodic hemodynamic changes. Although specific anesthetic drugs have been recommended, we believe that optimal preoperative preparation, a gentle induction of anesthesia and good communication between surgeon and anesthesiologist are most important for anesthetic management.
