To clarify the mechanism of the protective effect of hemodialysis on lipid peroxidation in RBC membrane structures, the level of malondialdehyde (MDA) which is the lipid peroxidation product, and the activities of antioxidant enzymes such as superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH-Px) were determined before and after hemodialysis in the RBCs from 20 patients with end stage renal disease (ESRD), and from 14 healthy subjects. Before dialysis, MDA levels in the RBCs from the patients with ESRD were higher than those from healthy controls. SOD and catalase activities in the RBCs were lower. After hemodialysis, MDA, SOD, and catalase in the RBCs from the patients with ESRD were normalized. These results indicate that hemodialysis treatment is helpful to protect the peroxidative darnage through normalizing the activities of antioxidant enzymes.

Splenic abscess is an uncommon lesion and may be present either as a localized area of infection in the spleen or as a part of generalized sepsis. The diagnosis is difficult because of the rather nonspecific clinical picture. Hence, splenic abscess has a high mortality rate and is after diagnosed only at autopsy. Computerized tomography (CT) offers the clinician a reliable tool for the diagnosis of intra-abdominal abscess. A successful outcome is dependent on an early diagnosis and prompt treatment by splenectomy with antibiotic cover. We experienced a care of splenic abscess which was diagnosed by CT and treated by splenectomy with antibiotics. Postoperative course was relatively uneventful.

Leriche syndrome is a chronic disorder mostly in male and is a specific symptom complex due to thrombotic obliteration of the aortic bifurcation as result of an atherosclerotic change. The symptoms include 1) extreme liability to fatigue of both lower limbs; 2) symmetric atrophy of both lower limbs; 3) pallor of the legs and feets; 4) inability to maintain stable erection. There are several methods for surgical management of this disorder; 1) thromboendarterectomy with or without sympathectomy; 2) aortoiliac bypass graft; 3) aortofemoral bypass graft. Here we report a case of Leriche syndrome which was successfully managed with aortobifemoral bypass graft with Dacron and reviewed literatures on it briefly.

The purpose of this study was to confirm the formation of hybrid layer and resin tags in dentin tissue and the possibility of bonding between luting cements used for the prosthesis and the resinous surface coated with resin bonding agents to prevent the dentin hypersensitivity after abutment preparation. Some resin bonding agents, which may have the possibility of bonding with polyacrylic acid as a liquid ingredient of polycarboxylate and glass ionmer coments, were selected. All-Bond desenstizer containing NTG-GMA and BPDM, Scotch-Bond Multipurpose plus containing HEMA, and XR-bond cotaining organophosphate were selected as a coating agent. Dental cements were zinc phosphate, polycarboxylate, and glass ionomer cement. After the exposed dentin surface of premolars was ethced with 10% phosphoric acic and coated with resin bonding agents, the monophology of treated surfaces and the resin tags and hybrid layers on sectioned surfaces were observed by SEM. Shear bond strength between the resin bonding agents and 3 kinds of cements was measured 24 hours after bonding. On the debonded surfaces of the shear bond strength tested specimens, the cement tags and the bonding sites between the resin materials and cements were examined by SEM. Following conclusions were drawn : 1. Coating of dentin with resin bonding agents had no effect on the shear bond strength of zinc phosphate cement. 2. Both of polycarboxylate and glass ionomer cements showed the increased shear bond strength by the dentinal coating with Scotch-Bond Multipurpose plus containing HEMA. However, in the case of dentinal coating with some agents containing NTG-GMA and BPDM or organophosphate, polycarboxylate cement exhibited the lowered shear bond strength, and glass ionomer cement showed the unchanged shear bond strength. 3. Complete obstructions of dentinal tubules were observed on the dentin coasted with All-Bond desensitizer or XR-bond, but distinct shape of the orifices of dentinal tubules was observed consistently on the dentin coated with Scotch-Bond Multipurpose plus 4. The hybrid layer was thickest on the dentin coated with All-Bond desensitizer, and the length of resin tags was longest one the dentin coated with Scotch-Bond Multipurpose plus. 5. On the debonded specimens which had been bonded with polycarboxylate cement or glass ionomer cement after coating with Scotch-Bond Multipurpose plus, the cement tags and the bonding sites between the resinous surface and the cements could be examined.

Rupture of the extensor tendon caused by a posteriorly displaced lunate fragment is an uncommon complication of Kienbock's disease. Thirteen cases have been reported in the English literatures, but it has never been reported in the Korean literatures. We report a case of rupture of the third and fourth extensor tendons secondary to advanced Kienbock's disease that was successfully treated by excision of the lunate and a tendon transfer.

The polyglandular autoimmune syndrome is constellation of multiple endocrine insufficiencies often associated with diseases of nonendocrine organs occurring in individual patients and their families. In 1980, Neufeld classified this syndrome into three major types. Type II is characterized by adrenocortical insufficiency, autoimmune thyroiditis, and insulin-dependent diabetes mellitus. We experienced a case characterized by adrenocortical insufficiency, autoimmune thyroiditis, and ovarian failure and report with the review of the literature. A 38-year-old woman visited our clinic because of progressing brown colored pigmentation of skin and mucosa which is developed a year ago. Nine years ago prior to visit, amenorrhea was developed after right oophrectomy. Three years ago, she revealed feature of hyperthyroidism such as palpitation, loss of body weight (8kg/1-2years), heat intolerance, and sweating, so received antithyroid therapy for 14 months. Brown colored pigmentation of skin and mucosa, especially scar and gingiva, has been progressively aggravated during last year. She had no past or family history of other endocrine disease. Diffuse pigmentation of skin, loss of axillary and pubic hair, and diffuse enlargement of both thyroid glands were shown on physical examination. Blood cell count, serum chemistry and blood sugar test were all within normal range. Basal hormone levels were T3-uptake 29.7% (30~40), T3 153 ng/dL (85~185), T4 7.5ug/dL (5.5~11.5), TSH 2.4 IU (0.34~3.5), anti-TG antibody <100 U/mL (0~100), anti-microsome antibody <50 U/mL (0~100), TBII (thyrotropin binding inhibiting immunoglobulin) 2.2% ( (-15)~15), ACTH 989 pg/mL (0~37), cortisol 0.1 ug/dL (5~25), renin 7.1ng/mL/hr (1~2.5), aldosterone 81.0pg/mL (50~194), LH 115.2 mIU/mL (0.6~16.8), FSH 122 mIU/mL (1.6~19.0), and estradiol <10.0pg/mL (30~120). In ACTH stimulation test, levels of basal cortisol, 30 minutes, and 60 minutes were <0.1, <0.1, and <0.1 g/dL respectively. And, in glucagon stimulation test, levels of basal C-peptide, 5 minutes, 10 minutes, and 15 minutes were 0.9, 5,1, 6.3, and 5.5 ng/dL respectively. Thyroid scan showed diffuse enlargement of bilateral thyroid glands and pelvic ultrasonogram showed atrophy of left ovary. We administered corticosteroid, estrogen, and progesterone which were deficient to the patient, and has followed up the clinical course of the patient.

OBJECTIVES: Our purpose was (1) to determine whether amniotic fluid concentrations of interleukin-6 are of value in the diagnosis of histologic chorioamnionitis of preterm placenta and in the prediction of significant perinatal morbidity and mortality in patients with preterm premature rupture of membranes and (2) to compare the diagnostic performance of amniotic fluid interleukin-6 with that of amniotic fluid microbial culture for these outcome variables. METHOD: The relation among placental histologic finding, perinatal outcome, amniotic fluid culture, and amniotic fluid interleukin-6 concentrations were examined in 65 patients with preterm premature rupture of membranes who delivered preterm neonates within 72 hours after transabdominal amniocentesis. Interleukin-6 level was determined by enzyme-linked immunosorbent assay. Receiver-operator characteristic curve, Mann-Whitney U test, and Fisher's exact test were used for analysis. RESULTS: 1) Patients with acute histologic chorioamnionitis had significantly higher median amniotic fluid interleukin-6 concentrations than those without histologic chorioamnionitis (median 12.6 ng/ml, range 0.03 to 142.2 ng/ml vs median 0.5 ng/ml, range 0.03 to 16 ng/ml; P < 0.0001). 2) Amniotic fluid having interleukin-6 concentrations higher than 3.2 ng/ml had a sensitivity of 78% (35/45) and specificity of 95% (19/20) in the diagnosis of acute histologic chorioamnionitis and sensitivity of 74% (25/34) and specificity of 65% (20/31) in the prediction of significant neonatal morbidity and mortality. 3) These sensitivities were significantly higher than those of amniotic fluid culture, but there were no significant difference in specificities between amniotic fluid interleukin-6 and culture (histologic chorioamnionitis: 78% vs 51%, p<0.01; significant neonatal morbidity and mortality: 74% vs 47%, p<0.01, respectively). CONCLUSIONS: Test of amniotic fluid interleukin-6 is of value and more sensitive than amniotic fluid culture for the antenatal diagnosis of histologic chorioamnionitis and for the prediction of perinatal outcome in patients with preterm premature rupture of membranes.
