Most renal carcinomas are thought to originate from the epithelial cells of proximal convoluted tubules in the renal cortex. Collecting duct carcinoma is a recently recognized histological variety of renal cell carcinoma considered to arise from the epithelium of the collecting ducts. It is important to distinguish the collecting duct carcinoma from ordinary renal cell carcinoma, because which has an aggressive clinical course with early metastasis and death. But in patients, the natural course of the disease and its response to treatment have not been clearly established. Herein we report a case of collecting duct carcinoma of kidney in 38-year-old woman who had generalized edema and left flank dull pain. The preoperative diagnosis was left renal cell carcinoma on physical examination and radiologic finding, and left radical nephrectomy was done.

Percutaneous needle biopsy of pulmonary lesion with use of fluoroscopic guidance is well estabilished as a diagnostic tool but limited by the small size and inaccessibility of certain lesions. However, percutaneous needle biopsy'has been used increasingly in relation to advance and the salty of smaller biopsy needle and new imaging modalities such as ultrasound and CT. CT, because of its characteristics of high resolution, allows tissue sampling with considerable safty from area that heretofore could not be visualized under fluoroscopy. The authors summarized 44 pulmonary lesions that underwent CT-guided transthoracic biopsy with fine-needle over a 14 month period and analyzed the sensitivity of PTNB. -CT-guided PTNB was done with 20 gauge or 22 gauge Westcott biopoy needle (Mann medical products, USA). A diagnosis was made in 27 of 44 cases (61%) including malignany in 19 of 24 cases and benignancy in 8 of 20 cases. The pulmonary mass lesions were located at the peripheral zone of the lung field in 33 cases and at the central zone in 11 cases. Complications were observed in 2 cases which were pneumothorax and hemoptysis each but specific therapy was not required The sensitivity of PTNB by one session was 61% (27/44). The sensitivity of malignancy was 79% (19/24) and benignancy was 40% (8/20). These results suggest the usefulness of PTNB using fine needles be increased in eariler diagnosis and improved staging of pulmonary nodular lesions without significant complications.

In order to observe the development of ventricular arrhythmia during regional myocardial ischemia and reperfusion, especially under the presence or absence of ST-T electrical alternans on epicardial EKG. The proximal left descending coronary artery(LAD) was ligated for 20 minutes and then reperfused suddenly in twenty-three cats. Standard lead EKG(Lead??, chest lead EKG and epicardial lead EKG were recorded simultaneously during the occlusion and reperfusion respectively. During the ligation of LAD, STEA was observed in thirteen cats(56.5%). In occlusion period, the incidence of ventricular tachycardia in STEA positive group was significantly higher than in the negative group(p<0.01) and arrhythmic score was significantly higher(p<0.005) also In the reperfusion period the incidence of vefntricular fibrillation in STEA positive group was significantly higher than in the negative group(p<0.025). But there was the tendency to be higher in arrhythmic score of STEA positive group. There were no differences in heart rate, systolic left ventricular pressure, ST elevation and ST width in both groups. Most forms of ST-T of sinus rhythm before and after development of ventricular premature beat was low form(L). It was concluded that at the presence of STEA on EKG, the incidence of ventricular arrhythmia was more prevalent. So, STEA can be available as a marker of ventricular arrhythmia and prognostic factor.

This research was focused on overall examination of tissue alteration, wound healing promotion. After the hair on the dorsal surface was shaved, 5x5mm oval skin defect was formed. Experimental wounds of right side were irradiated on every day for 90 second with Ga-Al-As semi-conductor laser. Left side wounds served as control group. The rats were sacrificed on the 1st, 3rd, 5th, 7th, 14th, 21th day. For light microscopically, parafin section were stained with H&E, MT. The outcomes were as follows : 1. On 1st day, experimental and control group were seen acute inflammatory cell infiltration, edema. 2. On the 3rd days, both groups were seen crust development, collagen, blood vessel proliferation. 3. On the 5th days, experimental group were reduced edema and inflammatory cell infiltration than control group. 4. On the 7th days, both groups were observed edema, inflammatory cell infiltration disappearance and keratinocytes motility from wound defect. 5. On the 14th days, experimental group appeared collagen, blood vessel proliferation and hair follicle than control group. 6. On the 21th days, both groups were seen normal status re-epithelization. According to the above results, The wound-healing stimulated by laser radiation involves an increased rate of epithelial growth. LLLT was confirmed that it has fibroblast, blood vessel proliferation, influence initial wound healing process.

A study on changes of serum HDL-cholesterol level in various diseased states was performed. Diseased groups were nephrotic syndrome, liver cirrhosis, hyperthyroidism, hypothyroidism and chronic alcoholism. Following results were obtained. 1) Compared to normal control group, levels of HDL-cholesterol in nephrotic syndrome were lower but the difference was significant statistically. 2) In liver cirrhosis, the result showed much lower levels than normal control group with high significance. 3) In both hyper-and hypothyroidism group, the levels of HDL-cholesterol were significantly lower than normal control group. 4) In chronic alcoholism, the levels were significantly higher than normal control group. 5) Except for the group of chronic alcoholism, the levels of HDL- cholesterol were higher in female groups than male groups, but was of no significance statistically.

In an effort to evaluate the usage of preceptorship in a department of family medicine, we analyzed the data which gathered during 10 months, from July 1990 to April 1991. The analyzed results were as follows ; 1. The number of precepting per preceptor was 3.5 during one day. 2. In the clinical learning, the residents needed instruction most frequently in the process for diagnosing the problems of their patients. 3. For the purpose of evaluating the teaching behavior of preceptors, we asked to 21 residents and 8 preceptors of the department who experienced the preceptorship for responding a questionnaire, which contained 30 questions. Residents perceived that the most contributable teaching behavior was "deals with students in a friendly, outgoing manner". Preceptors answered that behavior as "emphasizes problem solving approaches rather than solution per se". About the least contributable teaching behavior, residents and preceptors agreed that it was "emphasis on his/her personal research". For further improvement in clinical instruction and its evaluation, it would be necessary to develop a collaborative methodology for clinical instruction and to organize an ongoing professional communication.

General epidemiological data regarding herpes zoster (HZ) are necessary for treatment and prevention of this disease. In addition, epidemiological data can play an important role in evaluating the efficacy and impact of vaccination. Though several epidemiological studies of HZ in Korea have been conducted, they usually depend on hospital-based data and may not be representative of HZ characteristics all over Korea. The purpose of this study was to evaluate the incidence and other epidemiological features of HZ in the general Korean population. We used population-based medical records from the Health Insurance Review & Assessment Service, which includes 50,908,646 medical insurance subscribers, to calculate the incidence of HZ. Also, we analyzed an age-stratified random sample of 1,375,842 individuals to study descriptive epidemiologic characteristics of HZ in Korea in 2011. We observed that the incidence of HZ was 10.4 per 1,000 person-years and was strongly correlated with age. Sex had a major influence on HZ incidence; overall, there were 12.6 cases per 1,000 person years in women and 8.3 cases per 1,000 person years in men. There was no difference in incidence according to the locality and season.
