On 6 healthy adult males aged 20-30 years, oxygen pulse was observed during carrying sand bags weighting 10, 20 and 30kg on a level treadmill running with speeds of 3,4 and 5 km/hr. The results obtained were as follows. 1. Oxygen pulse during load carrying on a level treadmill was proportionately increased with an increase of work load, average oxygen uptake per minute. Regression equation of oxygen pulse (y: ml/beat) on the average oxygen uptake (x:l/min) required for each grade of work was expressed as y=3.34x + 5.99, sy.x=0.858. 2. Oxygen pulse reached the highest value 2-5 minutes after the start of load carrying, and thereafter it decreased gradually to some extend as the load carrying was continued. Rate of decrease in the oxygen pulse was gerater in lighter works. 3. In lighter works requiring less than 2.0 l/min of oxygen uptake, oxygen pulse was larger in case of carrying a losd by embrace, in both hands and on head than on back or on shoulder.

Osteogenesis imperfecta (OI) is an inherited disease of connective tissue disorder which represents a phenotypically heterogeneous group of conditions that results from a number of genetic defects in the synthesis of type I collagen. A pregnancy associated with osteogenesis imperfecta is considered a high risk pregnancy because the disease is associated with various metabolic and hematologic disorders, as well as well-recongnized skeletal abnormalities. In addition to the mother with OI, the offspring has about a 25% to 50% chance of being affected, therefore genetic counseling before conception and prenatal diagnosis should be offered to all affected mothers. Patients with OI present a series of problems and require a multidisciplinary approach in their management. We present a case of parturient with osteogenesis imperfecta with brief review of literature.

OBJECTIVE: To evaluate the changes of plasma MMP-2, -9 levels in preeclampsia between antepartum and postpartum periods, and compare with normotensive pregnant. METHODS: Plasma MMP-2, -9 levels were determined with enzyme-linked immunoassay in pregnant women with preeclampsia (n=20) compared to control group (normotensive pregnant women) matched by maternal age, gestational age, and parity (n=20). RESULTS: Women with preeclampsia presented significantly higher plasma level of MMP-2 before delivery [516.33 +/- 98.75 vs 384.55 +/- 93.84 (ng/mL), p=0.002]. In postpartum 24 hours, women with preeclampsia exhibited higher plasma MMP-2 level compared control group [534.77 +/- 158.67 vs 336.04 +/- 139.11 (ng/mL), p=0.002]. But the plasma level of MMP-9 was significantly lower in preeclampsia group before delivery [26.26 +/- 7.49 vs 45.00 +/- 20.31 (ng/mL), p=0.001]. In postpartum 24 hours, women with preeclampsia also speculated lower plasma MMP-9 level compared control group, but no existence of significance. CONCLUSION: Plasma MMP-2 concentration is significantly increased in preeclampsia before delivey and postpartum 24 hours. Plasma MMP-9 concentration is significantly decreased in preeclampsia before delivery.

Amniotic fluid embolism is rare but is one of the most catastrophic complications in the peripartum period. This syndrome is caused by a maternal anaphylactic reaction to the introduction of fetal material into the pulmonary circulation. When amniotic fluid embolism is suspected, the immediate application of extracorporeal mechanical circulatory support such as veno-arterial extracorporeal membrane oxygenation (ECMO) or cardiopulmonary bypass should be considered. Without the application of extracorporeal mechanical circulatory support, medical supportive care might not be sufficient to maintain cardiopulmonary stabilization in severe cases of amniotic fluid embolism. In this report, we present the case of a 36-year-old pregnant woman who developed an amniotic fluid embolism immediately after a cesarean section. Her catastrophic event started with the sudden onset of severe hypoxia, followed by circulatory collapse within 8 minutes. The veno-arterial mode of extracorporeal membrane oxygenation was initiated immediately. She was successfully resuscitated but with impaired cognitive function. Thus, urgent ECMO should be considered when amniotic fluid embolism syndrome is suspected in patients presenting acute cardiopulmonary collapse.

PURPOSE: Acute immume thrombocytopenic purpura (ITP) is relatively common hematologic disease in children. Most acute ITP is recovered within 6 month spontaneously and the complication is rare. But 10~20% of the ITP patient became a chronic form. Infection with Epstein-Barr virus (EB virus) in developing country usually occurs during infancy and early childhood. Acute ITP associated with EB virus is likely to develop chronic ITP in current literatures. We studied the pattern of laboratory findings in long term follow up of ITP with EB virus infection. METHODS: One hundred and seventy nine patients diagnosed with ITP admitted to the division of pediatric hematology, Gachon Medical Center and Hanyang University Hospital between Mar. 1991 and Jun. 2001 were reviewed retrospectively. Serologic test for EB virus was available for 57 patients and 25 of them were follow up at least 6 months. Evidence of acute EB virus infection was defined as a positive Viral Capsid Antigen (VCA) IgM or positive Anti VCA IgG and negative Ebstein-Barr virus Nuclear Antigen (EBNA). Complete remission (CR) was defined as a recovery of platelet count of more than 100 109/L and partial remission (PR) as a recovery of platelet count of 50~100 109/L, maintained for at least 6 months. RESULTS: Sixteen out of 57 patients were associated acute EB virus infection. Of this group, 8 patients were follow up at least 6 months. Forty one of 57 with no evidence of acute EB virus infection, 17 were follow up at least 6 months. The clinical and laboratory data was not different significantly in children with and without acute EB virus infection in admission. In EB virus infection group of 6 months follow up, platelet count was significantly lower than control group in 6 months follow up (P=0.006). Five patients of 8 (63%) with acute EB virus infection had chronic ITP and 2 of 17 (12%) with no evidence of EB virus infection had chronic ITP in follow up 6 months. CONCLUSION: Patients with EB virus associated ITP tended to resolved more slowly than those without EB virus infection and also showed tendency to become chronic ITP.

We have experienced one case of anesthesia for living related liver transplantation with propofol. The recipient was 18-month-old girl and 10.5 kg. She was suffered from congenital liver disease (biliary atresia). We decided propofol as an anesthetic agent of the recipient with permission of the recipient's parents. Total anesthetic time was about 13 hours and anhepatic phase was 110 min. Careful attention was paid to prevent infection, hypothermia, hepatic artery thrombosis and to keep proper lung function. Hemodynamic changes were relatively stable throughout the operation and postoperative mechanical ventilatory support was required for about 2 days.
