Three cases of sclerosing stromal tumor of the ovary are presented. All three patients were nulliparous young wemen of 23~25 years of age, presenting with menstrual irregularity for 6 months to 4 years. Grossly the tumors ranged in size from 8 to 22cm in greatest diameter, showing gray white to yellow solid or predominantly cystic tissue with serous fluid. The common microscopic finding was that of cellular areas admixed with densel fibrous and/or edematous tissue, presenting pseudolobular appearance. Two types of tumor cells were rounded cells with clear vacuolated cytoplasm and less numerous spindle shaped cells. Postoperative course was uneventful and menstrual irregularity disappeared postoperatively. In case 2, the patient got pregnant after 1 year and 4 months. This clinical course suggests that sclerosing stromal tumor of the ovary may be endocrinologically active.

A case of telangiectatic osteosarcoma of the proximal tibia of left leg in 19-year-old man was reported. Radiologically the tumor was aneccentric blow-out osteolytic lesion simulating aneurysmal bone cyst. Pathologically the tumor presented multiple blood filled cystic spaces and anaplastic spindle cells of osteoclastic type and focal osteoid deposition. The patient died 8 months after he underwent high above knee amputation followed by adjuvant chemotherapy. Distinct clinicopathologic finding of telangiectatic osteosarcoma was described with special emphasis on differential diagnosis.

BACKGROUND: The present study was performed to elicit what effect nalbuphine would have on isoflurane MAC (minimum alveolar concentration) in the patients undergoing lower abdominal surgery. METHODS: Sixty-two women were randomly allocated to one of five study groups to receive an intravenous injection of no nalbuphine (group I), 0.25 mg/kg (group II), 0.5 mg/kg (group III), 1.0 mg/kg (group IV), 1.5 mg/kg (group V). Anesthesia and tracheal intubation were induced with propofol 2 mg/kg, succinylcholine 1 mg/kg. Patients were inhaled at a preset end-tidal concentration of isoflurane, which was maintained for 20 min. Response to skin incision, movement or no movement, was determined 30 minutes after nalbuphine injection. The isoflurane concentration of the next patient in the same group moved up or down in steps of 0.1~0.3%, according to the previous patient's response. MAC was determined using the "up-down" method and logistic regression. RESULTS: The MAC's of isoflurane were 1.09 vol% end-tidal in the control group, 0.89 vol% in group II, 0.65 vol% in group III, 0.55 vol% in group IV, and 0.51 vol% in group V. CONCLUSIONS: It would be suggested that nalbuphine dose-dependently reduce the isoflurane MAC, and have ceiling effect on the reduction of isoflurane MAC.

In vivo 31P magnetic resonance spectroscopy (MRS) was used to evaluate the effect of nimodipine on changes of [H] (pH) and the ratio of [PCr]/[Pi] in cats subjected to an incomplete global cerebral ischemia-reperfusion under the pretreated condition of hyperglycemia. Animals were subjected to a transient (18 minutes) incomplete global cerebral ischemia; the systemic arterial hypotension was induced, and immediately followed by the bilateral carotid artery ligation. Twenty cats were divided into 3 groups; for group 1 (control), 7 cats were employed for a control group; for group 2 (hyperglycemia), 7 cats were a hyperglycemia group with infusion of 50% glucose prior to ischemia; for group 3 (Nimodipine), 6 cats were infused with 50% glucose prior to ischemia, and nimodipine after ischemia. The time course of changes in pH and [PCr]/ [Pi] was monitored before, during and after ischemia. The pH decreased immediately after ischemia in all three groups. After the reperfusion was made, the values of the pH did not retum to the baseline value for the group 2 (hyperglycemia) and 3 (nimodipine), in contrary to the group 1 (control). The ratio of [PCr]/[Pi] was dropped to 20% of the baseline value after ischemia in all three groups. The value was recovered progres- sively during reperfusion period for group 1 (control), whereas for group 2 (hyperglycemia) and group 3 (Nimodipine) the values were remained depressed. The results suggest that the condition of hyperglycemia induced by the infusion of 50% glucose prior to the incomplete global cerebral ischemia-reperfusion, may deteriorate the cerebral ischemia and the infusion of nimodipine during ischemia-reperfusion has no beneficial effects to improve the cerebral acidosis and the metabolic recovery.

PURPOSE: To report two case of oculomotor palsy accompanied by herpes zoster ophthalmicus (HZO). CASE SUMMARY: Two patients with HZO who were suffering from skin lesions, facial pain, and medicated with an antiviral agent from the dermatologic department, were diagnosed with oculomotor palsy. They presented with ptosis, dilated pupils, and ophthalmoplegia after 10 days, and 4 days after began developing skin lesions. They were diagnosed with HZO-induced oculomotor palsy and the ophthalmoplegia improved in all cases. CONCLUSIONS: Oculomotor nerve palsy rarely occurrs in HZO patients and is usually followed by skin lesions. We recommend examinations for functions of extraocular motility, ptosis, and pupil to diagnose and treat the HZO-induced oculomotor nerve palsy even if consulted with the dermatologic department or only showing mild conjunctivitis, episcleritis, or keratitis.

In order to evaluate contamination of the topical eye drugs, 112(36 kinds) medications used over 1 month by the patients and 80(25 kinds) medications used at OPD(outpatient department) were studied by culturing the caps, the tips and the contents. Coagulase-negative staphylococcus was mainly isolated from the caps and the tips(p<0.05). But the other gram-positive bacteria, gram-negative bacteria and fungi were isolated from all medication sites. The most frequent site of contamination was the tips of the medications. Frequency of contamination based on detail of medications and preservatives of medications was not statistically significant(p>0.05). The medications used by the patients for a long time in comparison with the medications used at OPD were significantly more likely to be contaminated(p<0.0001). Therefore, we think that the topical eye durgs should be used with proper instillation and storage for a short period because of increase risk of contamination.

Seventy five cases of squamous cell carcinoma of the uterine cervix, invasion depth of which was less than 5 mm from the basement membrane, were reviewed during a period of 9 years from 1975 to 1983 at SNUH and investigated clinicopathologically by the following items; 1) lymphnode metastasis 2) vascular invasion 3) recurrence 4) pattern of invasion 5) cell type. Following results were obtained. 1) Lmyphnode metastasis was demonstrated in 4 out of 75 cases (5.3%). One of them had stromal invasion to 1.3 mm and the other three to a depth of 3.1 to 5.0 mm. 2) Vascular invasion was seen in 5 among the cases (6.7%) and well related to the depth of invasion. Vascular invasion did not occur in tumors with 3 mm depth of stromal invasion. 3) Three patients were with recurrence, treated by postoperative radiation. The depth of stromal invasion was over 2 mm in all of them. 4) The pattern of invasion was confluent in 26 out of 28 cases (92%) whose stromal invasion were over 2 mm depth, while only 3 confluency of 27 cases (11%) invaded less than 1 mm depth. 5) There was no good relationship between the tumor cell type and the depth of stromal invasion. Based on the above results, it is concluded that diagnostic criteria of microinvasive squamous cell carcinoma of the uterine cervix is stromal invasion not exceeding a depth of 3 mm from basement membrane of surface or glandular epithelium.
