BACKGROUND: It has been known that blood group antibodies are not produced in the neonatal period and that if the antibodies exist, they are probably maternal in origin which had crossed the placenta. There have been several studies conducted abroad on when these antibodies are formed but none has been done in Korea. This study was carried out to determine the ABO blood type and blood group antibodies in children from neonates up to 5 year old. We hoped to determine when and in what pattern blood group antibodies were produced. METHODS: We selected 337 children from neonates up to 5 year old who were admitted to Hanyang university Hospital in Seoul or Kuri from 1994 to 1996. Cell typing was done immediately by the slide method. The anti-A and anti-B used for cell typing were supplied by Immucor (Norcrosis, Ga) . Sera were stored at -70 degrees C until they were tested for ABO blood group antibodies by the standard saline test tube method. When uncertain results were obtained, a drop of the mixture was placed on a slide and observed under a microscope. RESULTS: ABO blood group antibodies were detected in 9 of 50 (18%) infants less than 1 week old and in 10 of 51 (20%) infants between 1 week and 3 months of age. The pattern of ABO blood group antibody production was similar to that of the fetal period up to 3 months after birth, after which antibody production increased rapidly to reach approximately 80% at 6 months of age, There was no difference in ABO antibody production between boys and girls. The antibody formation pattern of group A and group B infants less than 6 months of age showed anti-A to be 35% and anti-B to be 20%. In group O infants of the same age, anti-A was positive In 42% and antral-B In 33%. However, after 6 months of age, there was no difference in antibody production among groups A, B, or O. CONCLUSIONS: Antibodies directed toward ABO antigens were detected in 19 out of 101 (19%) infants less than 3 months old. We therefore believe it is necessary to Perform serologic typing as well as cell typing in these Infants. Furthermore, the emergency transfusion of type A or B blood to a type O infant under the impression that anti-A and anti-B do not exist should be forbidden.

The present studies were carried out, under natural room condition from June to July in 1969. The period required for growth of eggs and larva varied according to various temperatures and methods of rearing. The average number of eggs laid by the Culex pipiens pallens was 137 per egg raft. The period of gonotrophic cycle was from 3 to 6 days: incubation period of eggs was from 1.5 to 2 days: larva period was from 10 to 14 days: pupa period was from 2 to 3 days. Accordingly, the period from the beginning of gonotrophic cycle to the adult mosquitos in next generation required 25 days at the longest and 16.5 days at the shortest.

The aquatic quality of the Naktong river after two of three months in June, 1991 with phenol spillage from a electrical factory in Kumi was investigated. The samples were collected at six sites of the Naktong river basin and Kachang and Kongsan lakes. Phenol was not detected from all water samples. Turbidity was very much increased to the down stream in the Naktong river. The BOD and COD values exceeded the 2nd grade(3 mg/l) of the Korean standard quality of Environmental Water Act at the all sampling sites of the Naktong river. Especially, the value of COD at Kaejin (12.5 mg/l) was poorly classified as to the 5th grade of water class for the environmental quality standards. Organophosphorous pesticides such as parathion, malathion, fenitrothion and diazinon were investigated but not detected. Diazinon was only detected at the Ilson bridge(1.42 ppb), Okkye stream(6.95 ppb), Waekwan bridge(0.32 ppb), Gangjung reservior(0.13 ppb), Kaejin(0.05 ppb). Of the carbamates such as carbanyl, isoprocarb and cabofuran, the carbofuran was detected all sites except tap water, and Kachang and Kongsan lakes. The content of heavy metals such ans Cd, Pb, Zn, Fe, Mn, Hg were not exceeding for drinking water standards at the all sampling region, but only mecury was detected from Okkye stream(0.018ppb) and Kaejin(0.09ppb). In the regions of Kachang and Kongsan lakes, the content of heavy metals were lower than that of reservoir of Naktong river.

Preoperative angiography is frequently used in the planning of microsurgical reconstruction for identification of vascular abnormality that influence the planning of operation. But, recently 3D CT angiography is considered as new technique that can provide detailed information about vascular anatomy as well as soft and bony tissue without the risks of invasive angiography. 3D CT angiograms were performed in 19 patients before microsurgical reconstruction for the lower extremity and hand between May of 2003 and Oct of 2004. Sixteen of the studies were of the donor site and all of 19 studies were of the recipient site. No complications were found from the 3D CT angiograms. In one case of the bone exposed open wound, the injury of anterior tibial artery was identified and the zone of injury was adequately demonstrated. With the improvement in quality of CT imaging, 3D CT angiograms may provide a favorable alternative to invasive angiography. It is capable of providing high-resolution, three dimensional vascular imaging without the need for arterial puncture and prolonged post-procedure observation. The relation among blood vessels, bones, and soft tissue is well demonstrated in 3D CT angiogram. Also The acquisition time and examination cost were considerably lower in comparison with invasive angiography. In conclusion, this study demonstrates that 3D CT angiography may provide accurate, safe, and cost-effective preoperative imaging. The 3D CT angiography with relatively low morbidity, low cost, ease of image acquisition can have an broader role in microsurgical reconstructive surgery.

We report the result of a high-dose intravenous immunoglobulin therapy in a Henoch-Sch?nlein purpura patient with severe abdominal pain and nephrotic syndrom who did not respond to methylprednisolone pulse therapy. Kidney bbiopsy showed diffuse mesangial cell proliferative glomerulonephritis with fibrocellular crescent formation in approximately 50% of glomeruli. Mesangium of all glomeruli were strong positive for IgA and C3 antibodies. High-dose intravenous immunoglobulin treatment was introduced and dramatic improvement of gastrointestinal symptom and proteinuria as well as hematuria was noted. Immunoglobulin administration should be considered in Henoch-Schnlein purpura patients with sterois-resistant intractable dastrointestinal manifestation and renal involvenment.

The p53 gene, which resides on the short arm of chromosome 17, has been described as a tumor suppressor gene playing a role of G1 checkpoint monitering DNA damage, but mutation of this gene has been shown in numerous types of human cancers. The nm23-H1 gene encodes human NDP(nucleotide diphosphate) kinase. The expression of nm23-H1 gene was postulated to inversely correlate with metastatic potential of malignant tumors. We examined immunohistochemical expression in 30 cases of stomach cancers including 10 cases each of early gastric cancers(EGC), advanced gastric cancers without lymph node involvement, and advanced gastric cancers with lymph node involvement, which were stained with mouse monoclonal antibody of p53(PB53-12) and nm23-H1. Positive nuclear staining of p53 was frequently found in advanced gastric cancers with lymph node involvement (80%). The lymph node positive group showed high expression of p53(80%), and low expression of nm23-Hl(30%) than lymph node negative group. There was no significant correlation of p53 and nm23-H1 expression with tumor size, invasion depth, TNM stages, distant metastasis and histologic differentiation. Based on the present study, the expression of p53 and down regulation of nm23-H1 are thought to be correlated with tumor progression and lymph node involvement, and may be a useful prognostic factor in gastric cancers.

PURPOSE: To evaluate the accuracy and safety of ultrasound-guided biopsy of the thickened peritoneal reflections and to determine the efficacy and diagnostic role of this procedure in the differential diagnosis of peritoneal tuberculosis and peritoneal carcinomatosis. MATERIALS AND METHODS: Twenty-seven patients with only mildly thickened (25 mm or less) peritoneal reflections without apparent mass formations, and in whom imaging findings were not diagnostic, underwent ultra-sound-guided biopsy. Five-MHz linear or convex linear array transducers were used for ultrasound guidance,and an automated gun with 18-gauge (n = 23) or 20-gauge (n = 4) needles for tissue sampling. Biopsies were performed on the thickened parietal peritoneum (n = 9), greater omentum (n = 11), and small bowel mesentery (n = 7), and the results were compared with the final diagnosis determined by adiologic/clinical follow-up (n = 17) or laparoscopic biopsy (n = 10). Complications and changes in hemoglobin and hematocrit levels after the procedure were evaluated. RESULTS: Specimens adequate for pathologic examination were obtained in all 27 patients. The histopathologic results were metastatic carcinomatosis (n = 15), peritoneal tuberculosis (n = 8), and chronic granulomatous inflammation (n = 4). Specific pathologic diagnosis was obtained in all patients except the four with chronic granulomatous inflammation. Differentiation between benignancy and malignancy was possible in all patients and the histopathologic specific accuracy rate was 100%. No clinically significant complications were observed. In 24 patients with ascites at the site of the biopsy, transient bleeding was observed immediately after the procedure, but this stopped spontaneously within a few minutes. Post-procedural hemoglobin and hematocrit levels were only minimally lower (mean values of 0.9g/dL and 3.0%, respectively) than pre-procedurally. CONCLUSION: Ultrasound-guided biopsy of thickened peritoneal reflections is a safe and effective diagnostic procedure and is useful in the differential diagnosis of peritoneal tuberculosis and peritoneal carcinomatosis.

Dilated cardiomyopathy (DCM) is a multifactorial disease with enlargement and systolic dysfunction of one or both ventricles. Most of parturients having DCM would be advised to avoid or terminate her pregnancy owing to the high risk of cardiac overload that is likely associated with pregnancy. When maternal cardiac disease is observed, effective neuraxial analgesia may play an important role because a pain induced activation of the sympathetic nervous system during labor is associated with cardiovascular adverse effects, which may endanger the maternal and/or fetal well-being. Herein we report a case of a parturient with known DCM who received combined spinal-epidural anesthesia for labor and vaginal delivery. The maternal cardiac function and the effect of analgesia were evaluated by echocardiography during labor.
