Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

We have constructed several panels of MAbs which specifically recognize B-subunit of HCG (BHCG). Splenocytes from Balb/c mice immunized with B-subunit of HCG were fused with SP2/o-Ag14 myeloma cells by PEG method. Fifteen different hybridorna clones (individually named as mG10.127, mG10.61, mG9.5, mG9.18, rnG9.20, mG6.3, mG6.36, mG6.8, mG7.31, mG7.79, mG9.11, mG9.51.6, mG9.51.12, mH4.17, and mH4.4) were obtained by indirect ELISA screening and three to five successive cloning procedures. The distinct features of these MAbs were determined by specificity, western blot, isotyping, and isoelectrofocusing. All of the MAbs except mG9.20 and mG6.8 specifically bind to BHCG without cross- reaction with B-subunit of LH (BLH). In western blot analysis, all of the MAbs bind to non-denatured form of BHCG suggesting that the MAbs recognize conformation-dependent epitope of BHCG. This new panels of MAbs to BHCG should be useful for developing diagnostic reagent such as pregnancy, choriocarcinoma, Down's syndrome as well as for the fine quantitation of serum or urinary HCG.

Fumarase catalyzes the conversion of fumarate to malate in the Krebs cycle. Fumarase deficiency is a rare inborn error of metabolism and is inherited in an autosomal recessive manner. It causes mitochondrial encephalomyopathy. The symptom is characterized by developmental delay and hypotonia. We report here a case of a 32-month-old child who was initially refered because of spastic quadriplegia, delayed development and poor feeding.

The purpose of this study was to investigate the ability of cultured chondrocytes to prevent formation of bony bridge and possibly to repair of the damaged growth plate. Growth cartilage cells were obrained from the new born canine epiphyseal plates and was culture-expanded in high density. It took 14 days until formation of micro mass of cartilage cells which was easily removable from the culture flask. Twenty dogs were divided into two groups: group I (10), the medial side of growth plate of right proximal tibia was destroyed and cultured chondrocytes were homografted into the defect: and group II (10), the medial side of growth plate of right proximal tibia was destroyed and was left as it was. Left leg was served as a control. Serial radiological and histological observation were made until 16 weeks after homografting to determine the growth parrern. Following results were obtained. 1. In group I, 8 of 10 dogs had near normal growth with little angular deformity of the tibia, averaging 8° at post-op 16 weeks. Two dogs had 20° angulation at 16 weeks post-surgery. In contrast in group II, angular deformity was obvious at 4 weeks post-surgery, reaching 31° at 16 weeks post-surgery. 2. In group II, bony bridge was consistently formed on the medial side of the proximal tibia. In group I, the cultured chondrocytes initially appeared to be an amorphous cartiagenous mass, which, however, remained to contribute to matrix formation as time went on. 3. This study showed the ability of cultrued chondrocytes to prevent formation of bony bridge and possibly to repair the damaged growth plate. To prove the effectiveness of homografting of the growth cartilage cells for reconstruction of the growth plat, further studies should be followed.

OBJECTIVE: To determinate the reference values of residual latencies of motor nerves and to evaluate the early diagnostic value of residual latency. METHOD: The subjects were 129 diabetes mellitus patients and 60 controls with no known neurological disorders. The patients were divided into two groups based on the conventional nerve conduction study: Group 1, 75 patients without neuropathy; Group 2, 54 patients with neuropathy. The group 2 patients were subdivided into 4 sub- groups on the basis of conduction velocity and residual latency of the median nerve. Residual latencies were measured in all subjects and glycosylated hemoglobin percentages (HbA1c) were measured in the diabetes patients. In group 2, each nerve conduction parameter was correlated with the duration of diabetes and HbA1c. The duration of diabetes, HbA1c, and amplitude of median nerve response were compared between the subgroups of group 2 patients. RESULTS: Motor residual latencies obtained from the controls were 1.93+/-0.28 msec, 1.53+/-0.24 msec, 2.46+/-0.43 msec, 2.21+/-0.53 msec in median, ulnar, deep peroneal and posterior tibial nerves, respectively. In group 1, motor residual latencies of median & deep peroneal nerves were significantly delayed compared with those of the controls. In group 2, motor residual latencies of median, ulnar, deep peroneal and posterior tibial nerves were significantly delayed more than those of the controls and group 1. In group 2, increased HbA1c correlated to the decreased conduction velocities of median, deep peroneal, posterior tibial nerves but not to the residual latencies. In the subgroup of group 2 (2-D), the nerve involved more distally showing lower compound muscle action potential and higher HbA1c. CONCLUSION: Residual latency measurement can be a useful diagnostic method for the early detection of diabetic neuropathy.

A survey was conducted to determine the extent of intestinal parasite infection in Bat Dambang, Cambodia in March 2004. A total of 623 fecal specimens was collected from kindergarten and schoolchildren and examined using the formalin-ether sedimentation technique. The overall infection rate of intestinal parasites was 25.7% (boys, 26.2%; girls, 25.1%), and the infection rates of intestinal helminthes by species were as follows: Echinostoma sp. 4.8%, hookworm 3.4%, Hymenolepis nana 1.3%, and Rhabditis sp. 1.3%. The infection rates of intestinal protozoa were; Entamoeba coli 4.8%, Giardia lamblia 2.9%, Iodamoeba butschlii 1.4%, Entamoeba polecki 1.1%, and Entamoeba histolytica 0.8%. There were no egg positive cases of Ascaris lumbricoides or Trichuris trichiura. All children infected were treated with albendazole, praziquantel, or metronidazole according to parasite species. The results showed that intestinal parasites are highly endemic in Bat Dambang, Cambodia.

BACKGROUND: Up to now, no study have been reported about clinical features of ESRD patients at the initiation of dialysis and their outcomes in Korea. We studied the clinical features and survival predictors of ESRD patients at the initiation of dialysis therapy and their outcomes and we tried to identify the optimal point of starting dialysis therapy according to age, underlying disease, and other variables. METHODS: We studied retrospectively clinical and laboratory variables of initiation in 364 patients who started dialysis therapy first at Korea University Guro hospital from 1987 to 1997. We divided patients into 3 groups by age, into 2 groups by underlying renal disease(DM vs. nonDM) and compared the above variables between 3 or 2 groups. We evaluated the outcome(alive vs. death) in 258 patients whoes outcomes were identified. We identified the poor survival predictors of outcome according to alive / death group, and analized the relative risk of death according to level of serum creatinine (reference: 12.5-15.0 mg/dL) and serum albumin (reference: 4.0-4.5 g/dL). RESULTS: 1) The distribution of patients by age, young age group, middle age group, old age group were 135, 140 and 89. Those of patients by underlying renal disease, DM and nonDM were 80 and 284 respectively. 2) The most common underlying renal disease of young age group was chronic glomerulonephritis but that of old age group was diabetes mellitus. In old age group, levels of BUN, serum creatinine, and serum phosphate were lower than those in young age group(P<0.001). In old age group, the indication of dialysis tended toward relative(p=0.098) and early referral was more common than in young age group. 3) DM group was older and more early referred than nonDM group. In DM group, blood cholesterol level was higher, but level of BUN, serum creatinine, albumin, phosphate and uric acid were lower than those in nonDM group. 4) In 258 patients whose outcomes were identified, elderly and DM had poorer outcomes in the respect of mortality and survival by Kaplan-Meier survival analysis method. In the comparison of death group and alive group, death group was older and had more DM as underlying renal disease and lower level of serum creatinine than alive group. 5) Relaive risk of death was higher in lower concentrations comparing to reference level of albumin and creatinine. CONCLUSION: Old age, DM as underlying renal disease, hypoalbuminemia and hypocreatinemia were poor survival predictors. Then close observation and follow-up are warranted in patients with old age, DM, hypoalbuminemia, and hypocreatinemia. For more favorable prognosis in ESRD patients, early initiation of dialysis must be considered in patients who have these characteristics.

PURPOSE:Present evidences suggest that Ureaplasma urealyticum is a cause of pneumonia, septicemia, and bronchopulmonary dysplasia (BPD) in newborn infants, particularly those born prematurely. The purpose of this work was to examine the relationship between Ureaplasma urealyticum in the tracheal aspirates and adverse outcomes, such as BPD and early onset neonatal sepsis in premature infants. METHODS:A polymerase chain reaction (PCR) was performed on tracheal aspirates collected within 24 hour after birth in 176 premature infants less than 35 weeks of gestation and admitted to the neonatal intensive care unit of Bundang CHA Hospital. RESULTS:U. urealyticum was detected in 37 of 176 preterm infants (21.0%). Gestational age (29+5+/-2+5 wk vs. 30+6+/-2+5 wk, P=0.013) and birth weight (1.39+/-0.44 kg vs. 1.59+/-0.55 kg, P=0.037) were lower in the U. urealyticum-positive group compared to the control group. The incidence of early onset neonatal sepsis (16.2% vs. 6.5%, P=0.045) and BPD (45.9% vs. 29.5%, P=0.047) was higher in the U. urealyticum-positive group compared to the control group, but the severity of BPD was not different between two groups. However, multiple logistic regression analysis revealed that the presence of U. urealyticum was not independently related to the development of early onset neonatal sepsis and BPD. CONCLUSION:The results suggest that colonization of the lower respiratory tract by U. urealyticum might not be related to the development of neonatal sepsis and BPD directly in preterm infants.

PURPOSE: To evaluate the results of surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum for chronic lateral ankle instability. MATERIALS AND METHODS: From April 2003 to August 2006, 62 patients with chronic lateral ankle instability were operated. There were 38 males and 24 females with a mean age of 39.6 years (range, 18~61 years). Mean follow-up period was 32 months (range, 10~48 months). All patients were checked with preoperative ankle anteroposterior and lateral view, stress anterior drawer and varus test using Telos device. The clinical results were graded according to the VAS and AOFAS scale. RESULTS: VAS score improved from preoperative 8.2 points to 3.1 points. There were 38 patients who were excellent (above 90 points), 18 who were good (between 76 and 90 points), 5 who were fair (between 60 and 75 points), and 1 who was poor (below 60 points) according to the AOFAS ankle and hindfoot scale. The excellent and good results amounted to 90.3%. CONCLUSION: Surgical reconstruction of lateral capsule-ligament complex with reinforcement by periosteal flap of distal fibula and inferior extensor retinaculum is believed to be a effective method for chronic lateral ankle instability.
