Cobalt 원격조사가 정상 성숙웅성 백서의 생식장기에 미치는 영향에 관한 병리조직학적 연구
한정철(JC Hahn) 대한산부인과학회 1972 Obstetrics & Gynecology Science Vol.15 No.7
In order to study the histological effects of therapeutic doses of 60Cobalt-teleirradiation to the rats after daily tissue doses of 200 rads, to 3 x 5cms fields to the lower abdomen, to total doses of 200, 600, 1000, 2000, 3000 and 4000 rads, the lower abdominal skin, vagina, uterine cervix, uterine corpus, oviducts, ovaries, urinary bladder, rectum and bone marrow were extirpated. after sacrificing the animals 24 hours after the last dose, and microscopically examined after ordinary tissue preparatory processing. The experiment led to the following conclusions: 1) 60Cobalt-teleirradiated rat skin showed disappearance of the stratum corneum and stratum granulosum, chromatolysis, piknosis and vacuolization of the epidermal and hair follicle epithelium after doses of 1000 to 4000 rads. 2) 60Cobalt-teleirradiated rat vagina and uterine cervix disclosed desquamation of the cornifying layer, degenerative changes of the mucosal epithelium and mucosal thinning after doses of 1000 to 2000 rads. 3) The mucosa of the corpus uteri and the oviducts irradiated with 60Cobalt revealed slight cellular degeneration after 3000 to 4000 rads. These organs therefore appear to be the most radioresistant within the female reproductive system. 4) 60Cobalt-teleirradiated ovaries showed marked degeneration of ovocytes and follicular cells throughout the range of primitive to mature follicles after doses of 600 rads. 5) The mucosa of the rectum was relatively more radioresistant than that of the urinary bladder. 60Cobalt-teleirradiated urinary bladder showed slight degeneration of the mucosal epithelium after doses of 1000 rads. 6) The mean peripheral leukocyte count was depressed severely after 200 rads, as expected with the known high radiosensitivity of lymphocytes. marked alterations of the bone marrow were observed after doses of 200 rads. The first of the blood-forming cells destroyed were the erythroblasts and hemocytoblasts, mext the myelocytes and finally the megakaryocytes. 7) Microscopical findings showed an overall tendency of the ovaries, skin, vagina and the uterine cervix to be much more immediately radiosensitive than the corpus uteri, oviduct, urinary bladder and rectum.

부인과적 세포진에 있어서의 신속간이 Methylene Blue 염색법의 의의에 대하여
한정철(JC Hahn) 대한산부인과학회 1965 Obstetrics & Gynecology Science Vol.8 No.10
The author presents a rapid methylene blue monochrome staining method to evaluate applicability of this method in gynecological practice in comparison with Papanicolaou technique and reviewed the possibility of change of methylene blue stain to Papanicolaou stain. Examination of vaginal smears of 10 gynecological patients enabled a cytological evaluation of hormonal effects in various phases of menstrual cycle. Many suspicious cells were observed in all of 5 cancer patients. Among 295 outpatients, by using this technique as a preliminary means of cervical smears for the early diagnosis of cancer 80% of them were found to be `innocent` and therefore only the remainder 52 patients, which were suspicious or doubtful, were referred to the laboratory for further investigation by means of the Papanicolaou technique. The results after change of their stain were almost same as those of the original Papanicolaou method. The reservation that the gynecologist is trained in the technique and interpretation of vaginal smears the methylene blue staining method, supplemented if necessary by the Papanicolaou technique, can be recommended as a routine method for day-to-day use in practice.

Uterine rupture still remains as one of the most serious complication during pregnancy and labor, though it`s prophylaxis, diagnosis and treatment have been improved progressively. A case of spontaneous repture, due to neglected prolonged labor of Cephalopelvic dispropertion, a case of spontaneous rupture of the previous classical cesarean section scar at the last week of pregnancy, a case of traumatic rupture due to breech extraction and forceps delivery of the after coming hydrocephalic fetal head and a case of traumatic rupture occurred by the extraction efforts of the hydropic fetus are presented. The literatures on uterine rupture are reviewed briefly.
