OBJECTIVES: Dysfunctional uterine bleeding(DUB) is defined as abnormal bleeding from the uterine endometrium unrelated to anatomic lesions of the uterus, and its incidence is 10-15% among gynecologic diseases. We conducted this study for understanding correlation between clinical aspecets and pathological findings of DUB. Methods: We conducted a retrospective review of 599 women with DUB who underwent endometrial biopsy with special regard to the relation between pathologic findings and presenting symtoms or complaints from Jan. 1988 to Dec. 1997. RESULTS: Age distribution of DUB was mainly 5th decade, mean age was 44.1years, among various bleeding patterns, intermenstrual bleeding was the most common pattern(31.6%) and the next was menorrhagia(25.0%). Histologic findings of endometrium were proliferative phase, 327 cases(54.6%), hyperplasia, 139 cases(23.2%), secretory phase, 74 cases(12.4%) in order of frequency, and there was no difference in distribution of histologic findings among various bleeding patterns. CONCLUSION: Compared to other previoius studies, our study showed more incidence of endometrial hyperplasia, especially at age group of 40 or more. So patients aged more than this age with abnormal uterine bleeding must undergo emdometrial biopsy for pathologic diagnosis. Patients who are diagnosed endometrial hyperplasia must be carefully followed up because there are possibilities of progression to endometrial carcinoma.

We looked for and discussed the changes of curricula of medical course of 31 medical schools during the period of 1984 and 1993. The data used in this study were Educational State Report of Korean Med ical Schools published from Dean Association of Korean Medical Schools in 1984 and 1992-1993. The significant findings were as follows. 1. There were great variability in number of subjects and in time for lecture and exercise in each subject among 31 medical schools. 2. There were a great deal of changes during the period of 1984 and 1993. There were increased tendency in number of subjects and especially block lectures. Schools which had 1-4 subjects vanished in curriculum were most frequent among 22 schools during 9 years. Name of most frequent subjects in block lecture were clinico-patholo gical conference, reproductive medicine, hematology, oncology and cardiology in 1993. 3. Subjects which were transferred to pre-medical program were classified to two groups. One group was traditional basic medical subjects such anatomy, physiology and biochemistry, the other group was newly introduced subjects such as molecular biology and cell biology as basic medical subjects. 4. The data were suggested that long time was needed to stabilized in newly introduced subjects of clinical medicine such as neurology and plastic surgery. Time for lecture and exercise of these subjects shows increasing tendency in schools established before 1978, but decreasing tendency in schools established after 1978.

OBJECTIVE: To find out wheather the substance P takes part in the pain mediating system of uterus, and to ascertain the role of substance P in the hypersensitivity of hypogastric nerve to bradykinin during the uterine inflammation. METHODS: The uterus has two sensory innervations, which are the hypogastric nerve and the pelvic nerve. Since the hypogastric nerve is known to show increased sensitivity to bradykinin, a pain mediator, when the uterus is in inflammatory state, the hypogastric nerve recording was done for electrophysiological study of uterine pain-mediating mechanism in female SD rats (200-250 g). NK1 receptor antagonist (L-703,606) was injected through uterine artery before injecting bradykinin while uterus was under inflammation. RESULTS: The NK-1 receptor antagonist (L-703,606) decreased the spontaneous nerve impulse during inflammation, and it also decreased the hypersensitivity of the hypogastric nerve to bradykinin during the uterine inflammation. CONCLUSION: Substance P mediates the pain sense of hypogastric nerve, and it also plays a role in increased sensitivity of hypogastric nerve to bradykinin while uterus is in inflammatory state.

We have investigated and discussed the changes of scholarship, tuition and educational facilities in national medical colleges and private medical colleges for the period of 1984 and 1993. The data an alysed in this study were cited from the third edition and the seventh edition and raw data for the eighth edition of the Educational State Report of Korean Medical Schools which were issued by the Deans' Association of Korean Medical Schools. The significant findings were as follows: 1. In all investigated medical college libraries, the number of seats and medical books and the sorts of medical journals have increased, particularly the average budgets for medical journals have increased over 3 times in 1993 compare to 1994. 2. Between 1984 and 1993, total budget for scholarship have been increased out average benefit rate have been decreased from 38.6% to 34.3%. But the average benefit doubled its amount. 3. Average tuition in national medical college was about 52% of that in private medical college in 1993. In national medical colleges, average tuition for premedical course was 10% costly than medical course but it was just opposite to private medical colleges. 4. Between 1984 and 1993, Audio-visual aids have increased in number a little bit but there was nothing significant changes between national and private medical college. 5. Eighty one percent of investigated medical colleges have animal laboratory for research but only 15.6% of medical colleges have specific pathogen free rooms in the animal laboratories. 6. In 1993, the space in medical college buildings was occupied 29.6% by student education facilities, 25.8% by research space for professors and 10.5% by medical library. The average area for student educations was 42.4m2, for professors research was 32.2m2 and for library was 11.4m2 per a student.

OBJECTIVE: Recently some reports suggested substance P and CGRP might be important factors for inflammation and hyperalgesia. This study was performed to see whether substance P or CGRP containing nerve fibers might be changed by mustard oil-induced inflammation. METHODS: After injection of mustard oil(5%) into uterine lumen, the uteri were removed and examined with immunohistochemical methods for substance P and CGRP. RESULTS: In the normal uterus, most of the substance P- or CGRP-immunoreactive nerve fibers were observed along the vascular structure and some in the myometrium, only few in the endometrium. Mustard oil did not changed this pattern of nerve fiber distribution but after 48 hrs, the amount of substance P or CGRP immunoreactive nerve fibers were greatly reduced compared with the normal uterus. It is not clear whether the decrease of substance P and CGRP immunoreactive fibers in the uterus was resulted from the depletion of the neuropeptides in the nerve fibers or the retraction of nerve fibers. CONCLUSIONS: These results suggest that the inflammation should cause the change of nerve fibers included in the nociception. This change may attribute the generation of inflammation and inflammatory hyperalgesia.

Benign cystic teratoma is the common ovarian tumor, and the incidence reported about 20%. Malignant transformation of mature cystic teratoma of the ovary is rare, which can develop with an incidence of less than 2%. The most common malignant tumor arising in mature cystic teratoma is squamous cell carcinoma which account for 75-85%, but vary rare cases of anaplastic carcinoma arising from mature cystic teratoma has been reported all over the world and prognosis of this malignant tumor was poor. No case of anaplastic carcinoma has been reported before in Korea. We experienced a case of anaplastic carcinoma arising from mature cystic teratoma of the ovary and report our case with a brief review of literature.
