BACKGROUND: Tourniquet pain is probably mediated by C-fiber. The ability of fentanyl to interrupt this nociceptive conduction was studied by administering either fentanyl or saline intrathecally along with hyperbaric bupivacaine for spinal anesthesia. METHOD: The incidence of tourniquet pain was evaluated in 60 patients having orthopedic surgery of the lower extremities during spinal anesthesia by administering either 30 mcg fentanyl (group 2) or saline (group 1) along with 0.5% hyperbaric bupivacaine 10 mg. We measured the maximal sensory spread of analgesia to pinprick, the incidence of tourniquet pain, and the sensory anesthesia to pinprick at the onset of tourniquet pain. RESULTS: The average maximal sensory spread of analgesia was the same in both groups (T9). The incidence of tourniquet pain was significantly greater in group 1 (33%) than in group 2 (10%). The sensory levels of anesthesia at the onset of tourniquet pain were not different in two groups. CONCLUSIONS: Intrathecal fentanyl was effective against tourniquet pain for 2 hours of the orthopedic surgery of the lower extremities.

We tried to analyze the status of 10 units of frozen thawed apheresis platelet concentration by 6% DMSO method for the evaluation of practical applicability. The platelet concentrations were transferred to PL-732(Baxter, USA) cryopreservation bag, and DMSO is added to those bag at slow rate until expected final 6% concentration is achieved, thereafter those were directly placed to -80 degrees C refrigerator for freezing. Someday later from I week to 1 month, those were thawed at 37 degrees C water bath, and then washed by same volume of ABO matched plasma. In the course of cryopreservation, about 7% of platelets were lost and the mean recovery rate of platelet was 93% compared with those of unfrozen status. LDH, the values of platelet lysis, and pH were within normal limits, whereas platelet aggregation test shows decreased aggregation to collagen and ristocetine compared with those of unfrozen status(p<0.05) but they were clinically acceptable. We suggest that the frozen platelets may be useful in a some clinical situation such as hematologic malignancy and solid tumor by autologous transfusion.

OBJECTIVE: To verify the separate and combined effects of cadmium and nickel on blood pressure in rats. METHODS: Following the daily administration of cadmium chloride(CdCl2) and nickel chloride(NiCl2) to rats both individually and in combination with intraperitoneal injection method for one week, systolic blood pressure of the tail was measured at 1 day and 5, 10, 20, 30 days after administration. Each substance was injected into the rats with 0.1 mg/kg bw and 1.0 mg/kg bw concentration. RESULTS: After 0.1 mg/kg bw CdCl2 was injected, a statistically significant difference was found as compared with the control group(only saline) after 1, 5 and 10 days. After 0.1 mg/kg bw NiCl2 was injected, a statistically significant difference was not found compared with the control group. After 0.1 mg/kg bw CdCl2 and 0.1 mg/kg bw NiCl2 were injected simultaneously, a statistically significant difference was found as compared with the control group after 1, 5 and 10 days and compared with 0.1 mg/kg bw CdCl2 group after 5 days and as compared with 0.1 mg/kg bw NiCl2 group after 5 and 10 days. After 1.0 mg/kg bw CdCl2 was injected, a statistically significant difference was found as compared with the control group after 1, 5, 10 and 20 days. After 1.0 mg/kg bw NiCl2 was injected, a statistically significant difference was found as compared with the control group after 1 day and 5 days. After 1.0 mg/kg bw CdCl2 and 1.0 mg/kg bw NiCl2 were injected in combination, a statistically significant difference was found after 1, 5, 10, 20 and 30 days as compared with 1.0 mg/kg bw CdCl2 after 10, 20 and 30 days and as compared with 1.0 mg/kg bw NiCl2 after 5, 10, 20 and 30 days. CONCLUSION: It was found that the effect of CdCl2 on blood pressure was much more than NiCl2 and a high concentration CdCl2 and NiCl2 in combination delayed the recovery of blood pressure.

Eighteen patients with primary hyperparathyroidism were treated by one of the authors (SKO) from 1981 through 1988 at the Department of Surgery, Seoul National University Hospital and the data were analyzed retrospectively. Eighteen patients comprised 6 males and 12 females, with the male to female ratio of 1 to 2. The age distribution was between 18 and 64 years. The chief complaints were associated with skeletal symptoms in 9 urinary symptoms in 5, and neurologic manifestation in 1 patient. There were 3 patients with asymptomatic hypercalcemia. All patients showed hypercalcemia and hypophosphatemia was found in 11 patients. Serum PTH level was elevated in 13 cases. performing preoperative localization with computed tomorgam, ultrasonogram and thallium-technetium subtraction scan, positive localization was made in 62.5% (10/16), 53.8% (7/13) and 85.7% (12/14), respectively. one patient, angiography and selective venous sampling were peformed and positive localization was made. All patients were treated by surgery. There were 17 patients with solitary adenoma and one with double tumors. Pathologic findings revealed adenoma of the parathyroid in all patients except one which was proved later to be carcinoma. There were no recurrent cases except one with carcinoma. There were no postoperative complications. primary hyperparathyroidism is a very rare disease in Korea. Causes of primary hyperparathyroidism in our study was confined to tumors of the parathyroid, such as adenoma and carcinoma.There was no hyperplasia causing primary hyperparathyroidism. Thallium-technetium subtraction scan was proved to be the best method for localization of the parathyroid tumors Excision of the tumor with involved parathyroid followed by frozen-section biopsy of the univolved parathyroid was the best way to treat primary hyperparathyroidism in our study.

OBJECTIVE: The purpose of this study was to evaluate of course of delivery & perinatal outcomes for postterm pregnancy compared with fullterm pregnancy. METHODS: This study included 360 cases of postterm pregnancy out of 16,992 cases delivered at Department of Obstetrics and Gynecology from January 1, 1993 to December 31, 1997. 16,143 cases of full term deliveries of 38 to 42 gestational weeks conducted in same period were used as the control group. Postterm pregnancy was defined as a pregnancy that it exceeds 295 days calculated from first day of the last menstrual period. RESULTS: The incidence of postterm pregnancy was 2.13% with the highest incidence occurring in the 26 ~30 years age group. This study group was significantly different from the control group in the incidence of fetal distress (10.28% vs. 2.20%), large fetus (10.83% vs. 6.95%), perinatal death (1.67% vs. 0.27%). CONCLUSIONS: Adverse perinatal outcomes were increased markedly as the gestational weeks to be prolonged. Therefore, careful prenatal care, accurate determination of delivery date is very important.
