The second-order rate constants for the reactions of phenacyl halides with piperidine in anhydrous acetone were determined, and the activation parametrs were also evaluated. It was found that the phenacyl bromide was more reactive about 222 times than the phenacyl chloride toward the piperidine, and that the values of entropies of activation were quite negative and those of enthalpies of activation were comparatively low. It, therefore, may be concluded that the reactions were to be S_N2 mechanism. Arguments are presented against the application of Kirkwood's equation in the reaction of phenacyl bromide with piperidine.

Lymphangiomas are divided into three categories; (1) simple (capillary) lymphangioma, (2) cavernous lymphangioma, and (3) cystic hygroma. This lesion usually occurs in the posterior triangle of the neck but can be present in the axilla, mediastinum, or groin. Recently, we have experienced two cases of cavernous lymphangioma that one occurred in the mediastinum and the other was in the right chest wall, which were surgically removed successfully and confirmed histopathologically.

황윤호,이양행,우종수,조광현 인제대학교 1986 仁濟醫學 Vol.7 No.4

심내막상 결손증(Endocardial cushion defect)은 선천성 심장기형의 약 3% 정도를 차지하는 비교적 드문 질환이며, 복잡한 동반 기형을 나타내고 있고, 그 수술 방법에 있어서도 많은 논란이 있으며, 사망율도 높은 질환인 바, 저자들은 지난 1년간에 3예의 본 증례에 대한 수술 치험에서 술후 3∼6개월간에 만족할만한 임상적 추적 결과를 얻었기에 보고하는 바이다. In Pusan Paik Hospital, Inje Medical College, there were two complete endocardial cushion defects (ECD) and a partial one, which were successfully repaired in 1986. In a patient of partial ECD, primum atrial septal defect was closed with pericardial patch. In a patient of complete ECD, associated with secundum ASD, pulmonary stenosis and Down's syndrome, the atrial and ventricular septal defects were closed separately with bovine pericardium and Dacron patches respectively, and then pulmonary stenosis was relieved by transannular patch widening in addition to valvotomy and infundibulectomy. In another patient with complete ECD, small interventricular communication was closed with simple suture with pledget, and primum ASD closed with pericardial patch. In all patient, the mitral clefts were closed with three or four 5-0 Prolene interrupted sutures. Transient A-V dissociation developed postoperatively in two patients, and heart failure in complete ECD with Down's syndrome was overcome with medical treatment.

To investigate the efficacy of endoluminal ultrasound system (EUS) as a surrogate for high frequency transvaginal ultrasonography and as an optional baseline study in determining parameirial and stromal invasion of early stage cervical cancer, 52 women suspected of cervical cancer underwent EUS. A 12 MHz endoscopic probe was employed to radially scan the cervix for possible lesions suspected to be invasive cancer during a period of 6 months from Feb. 1 to July 1, 1995. Patients also underwent magnetic resonance imaging (MRI) and/or computerized tomography (CT) as a routine mode of baseline study, and were clinically staged by 3 independent physicians specializing in Obstetrics and Gynecology at the Department of Obstetrics and Gynecology, School of Medicine, Ajou University, Suwon, Korea. Thirty one patients subsequently received surgery appropriate for the stage of the disease and the final pathology findings were compared with the results of clinical staging, EUS, MRI/CT by regression analysis. The results showed that there was statistically significant correlation between MRI/CT and pathology (r=0.660, p<0.02), between EUS and pathology (r=0.803, p<0.01), and between clinical staging and pathology (r=0.825, p<0.01). It is concluded that there was significant statistical correlation t>etween EUS, MRI/CT, clinical staging and pathology, but the question remained as to the statistical superiority of EUS over MRI/CT with regard to parametrial invasion and stromal invasion depth assessment. Finally, EUS is useful as an alternative optional diagnostic tool in the baseline study of cervical cancer.

Objectives : To evaluate an association between depression and altered immunity, we examined peripheral T lymphocyte or natural killer (NK) cell measures plasma ACTH and cortisol using the flow cytometry in acute and unmedicated patients with major depressive disorder (MDD). Methods : Forty-two patients with MDD from the outpatient clinic and forty normal controls from the hospital staff were recruited. We applied Hamilton Rating Scale for Depression (HAM-D) and Hamilton Rating Scale for Anxiety (HAM-A) for depressed subjects. Peripheral T lymphocyte or NK cell measures (CD3, CD4, CD8, or CD56) and plasma hormones (ACTH and cortisol) were obtained from all subjects. Results : There were no statistical differences in CD3, CD4, CD8, or CD56 between the two subjects. The number of CD56 cells negatively correlated with HAM-D scores (r= -0.42, P<0.01), but did not correlate with HAM-A scores in patients with MDD. The number of CD56 cells showed strong negative correlation with CD4/CD8 (r= -0.47, P<0.01) in the control group, but not in the depressed group. Patients with MDD had higher cortisol level than controls within the normal range. Conclusion : The trait of immunological imbalance and HPA axis abnormality were shown in patients with MDD. Especially, the severity of depression, but not the anxiety, could be reflected as decreased number of CD56 (NK T) cells in acute and Unmedicated state.

본 실험은 한국, 중국 및 일본 재래종 콩 유전자 자원의 주요형질 변이를 조사하고 이들 자원간의 지리적 유연관계를 비교하고자 수행하였으며, 그 결과를 요약하면 다음과 같다. 1. 경장은 한국(66㎝)이나 일본자원(54.9㎝)보다 중국자원(71㎝)에서 더 컸으며, 또한 변이도 중국자원에서 가장 큰 것으로 나타났다. 2. 개화일수 및 생육일수는 한국자원(65.5일, 151.4일)이 가장 길었으며 중국(57일, 120일)과 일본자원(59.9일, 122.4일)은 같은 경향을 나타냈다. 또한 한국과 중국자원은 지역에 따른 차이를 나타냈으나 일본자원에서는 확인할 수 없었다. 3. 백립중은 한국(18.8g), 일본(17.2g) 및 중국(14.7g) 순으로 무거웠다. 특히 한국자원은 9~11g과 23~25g에서 정점을 나타냈고, 변이폭도 가장 컸다. 반면 일본과 중국자원은 13~17g사이에서 정점을 나타냈다. 4. 협수는 중국(46.9개)이나 일본자원(36.5개)보다 한국자원(75.5개)에서 가장 많았으며, 변이폭도 한국자원에서 가장 컸다. 내도복성은 일본자원에서 가장 강하였다. 5. 정준판별분석결과 can 1을 경계로 하여 오른쪽 상하에 한국재래종이 주로 분포하였고 왼쪽에는 중국과 일본 재래종이 주로 분포하여 각 나라별로 고유한 영역을 가지고 분리되었다. 전체적 경향이 중국과 일본자원이 한국자원보다 가까운 경향을 나타냈다. This experiment was carried out to compare the characters of 944 Korean soybean landraces, 716 Chinese, and 170 Japanese soybean landraces introduced from USDA soybean germplasm collection. Cannonical discriminant and cluster analyses were conducted by their origins. The population from China was taller in plant height than those from Korea and Japan, also its variation was largest in Chinese population. The population from Korea was langer than those from China and Japan in terms of days to flowering and maturity. Also, Korean and Chinese accessions appeared the difference of those traits according to latitude. One hundred seeds weight was in the order of Korean(18.8g), Japanese(17.2g) and Chinese populations(14.7g), especially Korean population was distinguished into two groups; the group including accessions between 10 and 15g, and the other group including accessions between 20 and 25g. However, others showed the peak in range of 13~17g. The number of pod per plant was more in Korean accession(75.5) with the largest variation than Chinese(46.9) and Japanese accession(36.5). The distribution of Korean, Chinese and Japanese accessions reflected the origin of accessions analyzed by cannonical discriminant analysis. The relationship between their geographical origins showed the population of China and Japan are losely related.

Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).
