This study was a part of large scale of a prospective study on attitudes of professional students in medicine, nursing and teaching toward population related issues in Korea. The study was first conducted in May 1974 and then in May 1975 for the 1974 class cohot using a questionnaire consisted of attitude scales and other items developed by Lee. The purpose of study was two hold, namely, to determine the difference in students among specializations on one hand and between the first and second years in the 1974 class cohot regarding the subject matter. A one-way analysis of variance was used for attitude scale, and absolute and relative frequency were computed for the analysis of non-attitude scale items by employing Fishers' Ratio and Duncan's multiple range test at 5% level and chi square test at 5% level as significance tests. The hypothesis "students in health profession are more likely to have positive attitudes toward population related issues progressively as class year advances than students in teaching profession" was tested and the following results were obtained: 1) Nursing students were more likely to display favorable attitudes toward family planning than medical or teaching students although the class cohot showed slightly improved attitudes in the second year. 2) Respondents in general perceived national family planning program as a means of population control and this tendency was more true among nursing students as the class year advances than two other professional groups of students. Students in teaching profession appeared to perceive it more as a means to improve individual family welfare while health students were likely to see as to improve maternal and child health. This tendency was progressively improved as the class year advanced. 3) The majority of students regardless of their respective specializations believed that family planning program should be directed toward the improvement of individual family welfare. No progressive changes in the class cohot were observed. 4) About the plan to use contraceptives in future, no significant differences were observed among different specializations nor in different class years. However, the majority was confirmed to have a plan to use contraceptives in future. An increasing proportion of the undecided category was observed, as class year advanced among health students. 5) Students in health profession were found to be more favorable about "more leisure opportunities" as motive for limiting number of children whereas education students indicated the reasons as "facilitate ambitions" and "economic base". The progressive changes toward positive direction in both groups were observed as the class years advanced. 6) Attitudes toward induced abortions of the health student were observed to be positively related to class years while an inverse relationship was found in teaching students who showed much less favor in the subject matter than health students. This phenomenon may be due to the different exposure to learning environments unique to respective specializations. 7) Health students were found to have more favorable attitudes toward population education in general than the teaching students. The teaching students appeared to have changed more to the negative direction when they became the second year while no such development was observed in health students. The teaching students seemed to hold a very conservative position with regard to sex education on schools. 8) About the equality of sexes, the nursing group was found to be most favorable while the reverse was true in the teaching group. 9) About questions related to fertility values-the 10 percent of respondents regardless of specialization indicated that they would maintain their single status in future, however no change was observed in the second year. The desired number of children was found to be two by the majority of students in nursing, medicine and teaching in order of high proportion. No changes in a different class year were observed. The childless marriage was seen by nursing students as a problem more than other students, but a slight change in positive direction was found when the nursing students became the second year. In summing, as data supported in the above, students in health profession demonstrated more favorable attitudes toward population related issues than the teaching students were more conscious about the health aspect of population and family planning program while the teaching students gave more attention the socioeconomic aspect. The sex variable seemed to have operated in the item related to the equality of sexes. In conclusion, as data presented in the above, the hypothesis of this study was accepted except in the few items. It should be noted that the limitation of this study is the short duration of the observation in measuring the possible attitude changes. It should include curriculum analysis for the respective specializations in order to identify the area of curriculum impact on students in future study.

Augmentation cystoplasty is effective in the rehabilitation of the contracted bladder of small capacity caused by tuberculosis or interstitial cystitis refractory to more conservative methods of management. Genitourinary tuberculosis is the most common cause of contracted bladder in Korea and it may lead to considerable vesicoureteral reflux and progressive deterioration of renal function. The use of hemi-Kock ileal pouch with an afferent intussuscepted nipple is a suitable solution in patient in whom the bladder outflow tract provides adequate resistance and supratrigonal cystectomy is to be performed with construction of an antireflux mechanism. Herein, we report 4 cases of hemi-Kock ileocystoplasty.

Prazosin blocks the alpha-1 adrenergic receptor of sympathetic nerve. The effects of prazosin in patient with epidural lumbar anesthesia were analyzed with blind test. In a prospective randomized study, we compared a group of 25 patients who received prazosin with a control group of 58 patients. Forty-one( 70.7 %) of 58 patients developed acute urinary retention. In 11 of 25 patients(44 %), who were medicated with prazosin(3mg. per 18 hours) urinary retention was noted ( p >0.05). Mean catheterization rate in urinary retented patients was 1.61 in control group(41 cases), and was 1.27 in prazosin medicated group( 11 case) (p <0.05). Prazosin is an effective drug not only to prevent acute urinary retention but also to reduce the need for catherization.

From August l985 through June l987, ll patients were performed urinary diversion with Skinner`s modified Kock continent ileal reservoir. Postoperative follow up presently is between 2 months and 20 months. The following results were obtained. l. This operation was performed in 9 bladder cancers, I vesicovaginal fistula and l neurogenic bladder. 2. Early complications were acute pyelonephritis, wound infection, urine leakage of reservoir difficult self catheterization, acute renal failure, hepatic dysfunction and ileocutaneous fistula. 3. Late complications were asymptomatic bacteriuria, stone formation in reservoir, intestinal obstruction, incontinence and ureteral reflux. 4. Surgical management was applied for correction of incontinence or difficult self catheterization but the latter patient died of acute renal failure. 5. Progressive renal deterioration, metabolic disturbance, nutritional deficiency and electrolyte imbalance not been encountered in any cases.

The clinical and pathological features of a paraganglioma arising in the cauda equina is described and compared with previous reports. The right microscopic fetures were similar to those of paragangliomas from other sites, with a 'Zellballen' pattern of cells containing arzyrophil granules. Immunohistocytochemical stains for neurone specific enolase, S-100 protein, cytokeratin were positive, but stains for glial fibrillary acidic protein were negative. Electron microscopy showed densely staining membrane-bound granules, cilia like structures and fibros bodies in the cytoplasm. The last two features only occur in paragangliomas from this site. The pathological findings suggest that paragangliomas in this site arise from pre-existing paraganglia, possibly of the visceral autonomic group.

BACKGROUND: Coronary artery bypass grafts obtained from internal mammary artery(IMA) have a greater patency rate than do saphenous vein grafts(SVG). The release or production of endothelium-derived relaxing factor(EDRF), which regulates blood flow and inhibits platelets function, may contribute to the higher patency rate of IMA. In order to evaluate the difference between endothelium dependent relaxation in IMA and in grafted saphenous veins, we observed acetylcholine responses of IMAs and SVGs in humans. METHOD: Incremental dose if acetylcholine(Ach:A1-20, A2-50, A3-100microg) or single dose if acetylcholine(A3) were infused into the non-grafted IMA in 16 patients with different clinical presentation of coronary artery disease(3 with stable angina, 2 with acute myocardial infarction 4 with variant angina and atypical chest pain syndrome in 7). After the dose-response to Ach was completed nitroglycerine 200microg was injected into the IMA. Graded dose of Ach (A1, A2, A3) was also infused in 13 grafted saphenous veins(SVG). RESULTS: The overall vascular effects of Ach into the IMA were dilatory responses regardless of different clinical presentation. Two or 3 minutes after Ach injection, the diameter of IMA increased by 9.2%(A1) and 16. 7%(A3) respectively(p<0.01). Maximal dilatory response after A3 was comparable to that after nitroglycerin injection. Angiographically normal segements of SVGs also increased its diameter 2 minutes after Ach injection (7.2% with A1, 6.9% with A2 and 8.5% with A3). Thus the degree of relaxation of IMA was more prominent than that of SVGs. Angiographically dicreased segments of SVGs had no response after Ach injection. The overall responses of native coronary artery to Ach was dose dependant constriction. CONCLUSION: Injection of Ach to IMA and angiographically normal segments of SVGs caused vascular dilatation probably due to EDRF response. However the degree of relaxation was more prominent in IMA than in SVG. Angiographically diseased segments of SVGs had no response to Ach injection, suggesting that diseased SVG does not produce EDRF. However the finding of a consistent Ach-induced EDRF relaxation in the SVGs despite of constrictive response in the majority of native coronary arteries might suggest that the regenerated endothelial cell in the SVGs were probably of saphenous vein origin rather than derived from the coronary arterial endothelium.

Primary splenic tumors are rare and mainly found incidentally on radiologic studies. Among them, sclerosing angiomatoid nodular transformation (SANT) of the spleen is a new entity defined as a benign pathologic lesion. Most SANTs have no clinical symptoms and are occasionally accompanied by other splenic diseases such as malignancies. So, the exact diagnosis of the nature of the splenic tumor is mandatory for further treatment. But, preoperative diagnosis is not easy since it is difficult to obtain the tissue from the spleen for pathological study. Recently, laparoscopic splenectomy has become the more standard procedure for the spleen for diagnosis and treatment. Here, we report a rare case of SANT diagnosed following laparoscopic splenectomy.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.

Of several possible configurations of pin fixation of a displaced supracondylar fracture of the humerus in children, the medial and lateral crossed pinning technique has been known to provide the greatest resistance to gross rotational displacement. A new technique with ipsilateral two lateral crossed pins was devised so as to avoid the ulnar nerve injury with good stability for fracture site. During the period from 1992 to 1994, 18 children with displaced supracondylar fracture of the humerus were treated by closed reduction and ipsilateral two lateral crossed pinning. Eighty nine percents of the final results were satisfactory. There were no ulnar nerve injuries and fixation loss in all cases from the treatment. This is a safe, simple and reliable technique for providing the good stability of fracture site as well as avoiding the ulnar nerve injury.
