Small cell carcinoma of the ovary has been identified as a specific histopathologic entity. The first II cases were reported by Dickersin et a1, 1982, Since then only 80 cases were reported in literature. This rare and highly aggresive melignancy primarily affeets ehildren and young women(10-40) and grows rapidly, with hypercalcemia occuring frequently. Abscence of effective treatment results in early mortality. Recently we have experienced one case of primary sma11 cell carcinoma of the ovary, which is presented with a brief review of the literature.

PURPOSE: To investigate the effects of irradiation on the calcium content and calcific nodule formation in the MC3T3-E1 osteoblastic cell line. MATERIALS AND METHODS: Cells were irradiated with a single dose of 2, 4 and 8 Gy at a dose rate of 5.38 Gy/min using a Cs-137 irradiator. After irradiation, the calcium content and calcific nodule formation were examined on the 1st, 2nd, 3rd and 4th week. RESULTS: A decreasing dose-dependent tendency of the cell proliferation rate was found in all irradiated groups of this experiment when compared with the unirradiated control group. In accordance with the duration of culture, there was no significant difference in the cell proliferation rate after irradiation of 2 Gy when compared with the unirradiated group, however a decreasing tendency was found in 4 Gy- and 8 Gy-irradiated groups. While an increase in total calcium content after irradiation of 2 Gy was found at week 1, week 2, and week 4, there was a decrease in calcium content at week 1 through 4 in the 8 Gy- irradiated group. Calcific nodule formation was increased in irradiated experimental groups when compared with the unirradiated control group in the 2 Gyirradiated group, but decreased in the 4Gy- and 8Gy-irradiated groups at the same stage. CONCLUSION: The results showed a mild increasing tendency of the calcific nodule formation after irradiation of 2 Gy. However, a decreased calcific nodule formation in 4Gy- and 8Gy-irradiated groups was found. Taken together, the irradiation of 2 Gy mildly activated bone formation, however 4 Gy or 8 Gy suppressed bone formation by decreasing cell numbers in the MC3T3-E1 osteoblastic cell line.

Introduction of acrylic cement during total hip replacement has become popular in the las 30 years. Sometimes it precipitates severe hypotension and cardiac arrest, and may be due to toxicity of methylmethacrylae monomer. Fat embolism, air embolism, or neurogenic reflex may be other possible causes of the hypotension. The anesthetist should keep in mind these risk factors, and to prevent these adverse effects, the central venous pressure line, esophageal sterthoscope or Doppler ultrasonic transducer, and adequate fluid volume maintenance are required. We have experienced two cases of complication following bone cement insertion: One case developed severe hypotension and the other case cardiac arrest. The former occured under epidural anesthesia and the latter under general anesthesia after prosthetic implantation in a total hip replacement.

There is still controversy over applying enflurane anesthesia to cesarean sections in obstetrics. Clinical experience has suggested that the uterine depressant effects of halothane and enflurane are dose-dependent. In low concentrationss both agents have been used successfully as anesthetics for Cesarean section, whereas in higher concentrations, both have been employed when indicated to produce ceseation of uterine activity. The purpose of this clinical research is to investigate the impact of enflurane in low concentrations on neonates and parturients during Cesarean section. Sixty parturients for elective Cesarean section were divided into two groups. One group of parturients(l) were anesthetised with N2O-O2-thiopental-Thalamonal.The other group(ll) were anesthetised as the first group, except enflurane in low concentration added to the inhalation agent. Then group(l) was compared with the group(ll). Common aspects between the two groups are as follows: 1) No difference in blood gas status of maternal artery, umbilical vein or umbilical artery was identified. 2) Mean Apgar scores were above 8 point both 1 minute and 5 minutes after birth. 3) Mean neonatal neurological and adaptive capacity scores(NACS) were high both 15 minutes and 2 hours after birth. 4) Blood loss and administration of oxytocia during wurgery were almost the same. The results suggest that enflurane in low concentrations does not cause significant perinatal depression, and that fetoplacental exchange is well maintained during anesthesis. The anesthetic was well tolerated by the mothers and there were no instances of factual recall, no cardiac arrhythmia was observed, no significant hypotension was encountered and blood loss was not excessive. In conclusion, it is thought to be safe to add enflurane in low concentrations to general anesthesia in Cesarean section.

Clear cell sarcoma of kidney is highly malignant tumor that tends to occur in young infants, and has a tendency to metastasize to the bone. Our review of the literature disclosed 8 cases as to adults with clear cell sarcoma of kidney until December 1995. There was no report about it in the Republic of Korea. We report two adult patients, a young man and a young woman, who had a clear cell sarcoma of kidney.

Measurement of peak flow rate (PER) is useful to assess venilatory capacity of a critically ill patient and particulary in the evaluation of obstructive ventilatory disease because of it easy management. A number of studies have already shown the usefulness of PFR measurement for rapid determination of pumonary reserve, for preoperative assement of pulmonary function or in evaluating changes in patient's degree of pulmonary disability. In view of the close correlation between PFR & MBC(Maximal breathing capacity) peak flow determination should also be of value in patients in whom the MBC cannot be measured easily because of the patient's illness or lack of sustained cooperation. In this study, the correlation coefficient (r) was found to be 0.77 between PFR & MBC, 0.72 between PFR & FEV1(forced expiratory volume for one second) and 0.73 between PFR & VC(vital capacity). Therefore we think that the measurement of peak flow rate in detecting ventilatory disease or in following a patient's ventilatory capacity is recommended.
