OBJECTIVES: The purpose of this study was to get help in order to diagnose orthopaedic disease, measure its activity and determine treatment plan by measuring the beta-glucuronidase activity in urine, serum and joint fluid. METHODS: The beta-glucuronidase activity was determined in the serum, urine and joint fluid of the patients with degenerative arthritis, rheumatoid arthritis, osteomyelitis and osteogenic sarcoma, and some other disease to study the change of the enzyme activity. These values of each specimen were calculated by standard curve and treated by statistical analysis. RESULTS: The results obtained were summarized as follows. 1. The beta-glucuronidase activity in the serum, urine and joint fluid was increased in patients with degenerative arthritis, rheumatoid arthritis, osteomyelitis and osteogenic sarcoma etc. 2. The increased beta-glucuronidase activity in the serum and joint fluid of each disease does not show a specific finding about respective disease, but the increased beta-glucuronidase activity was statistically significant in the urine of all disease groups(male:p=0. 0041, female:p=0. 0001). CONCLUSIONS: On the basis of these results, it was suggested that beta-glucuronidase activity was affected by the orthopaedic disease and differed according to each specimen.

PURPOSE: Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We stuided correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. MATERIALS AND METHODS: 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. RESULTS: In All of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas involved in 9 cases, and other organ in 4 cases. CONCLUSIONS: The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

Echinococcus granulosus, an intestinal tapeworm of dogs and other canids, infects humans in its larval stage and causes human echinococcosis or hydatid disease. In the Republic of Korea, 31 parasite-proven human echinococcosis cases have been reported, most of which were imported from the Middle East. We recently examined a 61-year-old Korean man who had a large cystic mass in his liver. ELISA was negative for tissue parasitic infections, including echinococcosis, cysticercosis, paragonimiasis, and sparganosis. The patient underwent surgery to remove the cyst, and the resected cyst was processed histopathologically for microscopic examinations. In sectioned cyst tissue, necrotizing protoscolices with disintegrated hooklets of E. granulosus were found. In some areas, only freed, fragmented hooklets were detected. The patient had traveled to western and central Europe in 1996, and had no other history of overseas travel. We report our patient as a hepatic echinococcosis case which was probably imported from Europe.

In previous studies, the synergistic antiproteinuric effect of the combination therapy of ACE inhibitors and angiotensin II receptor antagonists (ATRAs) has been inconsistent in relation to underlying renal diseases. The influence from the blood pressure (BP) - reducing effect in some studies might also contribute to this inconclusiveness. To examine the possibility of the benefit being different according to underlying renal diseases, we undertook a crossover therapeutic trial of the combination therapy in two selected homogenous groups of patients with diabetic and non-diabetic renal diseases. The BP-reducing effect was excluded during the study. Nineteen biopsy-proven IgA nephropathy, as examples of non-diabetic renal diseases, and 24 type 2 diabetic nephropathy patients were selected as the study subjects. The subjects had to meet the follow criteria: a creatinine clearance (Ccr) between 25 - 90 ml/min/1.73 m2, 24-hr urinary protein excretion rate over 1.0 g/day and a BP maintained at less than 130/80 mmHg, with more than six-month therapy of ramipril, (5.7 +/- 0.4 mg/day, 13 +/- 2 month). The baseline data between the two groups showed no significantly differences. After a 12-week stabilization period (control period), 4 mg, once daily, dose of candesartan (combination period) followed by a placebo (placebo period), or vice versa, were administered in addition to the ramipril, for 12 weeks. The combination, with candesartan, did not change the Ccr, BP, serum and urinary electrolytes or the urea. The 24 hour urinary protein excretion rate was significantly reduced by the combination therapy in the patients with IgA nephropathy (3.1 +/- 0.3 g/day in combination, 4.2 +/- 0.3 in control, and 4.3 +/- 0.2 in placebo; p < 0.05). However, the patients with diabetic nephropathy showed no reduction in their proteinuria with the combination therapy (3.8 +/- 0.2 g/day in combination, 3.9 +/- 0.3 in control, and 4.1 +/- 0.3 in placebo; p=NS). The changes in proteinuria showed no relationship with the changes in the BP in IgA nephropathy. In conclusions, the benefit of combination therapy of its antiproteinuric effect was different between IgA and diabetic nephropathy over the 12-week trial. The difference in the pathophysiological role, and the importance of the renin- angiotensin system, between the two diseases might contribute to the discrepancy in the result. We suggest the discrimination of the underlying renal diseases in the study subjects is an important prerequisite for future studies on this issue.

In vitro ethylene-diamine-tetra-acetic acid (EDTA) dependent satellitism and phagocytosis of platelets by neutrophils have been considered to be rare phenomena. It is associated with pseudothrombocytopenia, abnormal histogram of platelets and pseudoleukocytosis on complete blood cell count (CBC) by automated blood cell counter, but these findings are not found in heparinized or sodium citrated blood. It has no clinical significance such as bleeding tendency or abnormal platelet function. EDTA dependent platelet satellitosis and phagocytosis must be differentiated from true thrombocytopenia. We report a case of EDTA dependent platelet phagocytosis by neutrophils in a 68 year-old male patient who was diagnosed as mycosis fungoides. His EDTA blood smear showed frequent phagocytosis of platelets by neutrophils and occasional platelet satellitism. The bood cell counts were within normal limits without pseudothrombocytopenia. Phagocytized platelets were confirmed by immunohistochemistry using GpIIb/IIIa antibody and transmission electron micrographs.

BACKGROUND: We investigated the effects of the common polymorphisms in the peroxisome proliferator- activated receptor gamma2 (PPAR-gamma2 Pro12Ala) and in PPAR-gamma coactivator 1alpha (PGC-1alpha Gly482Ser) genes on the association with the nephropathy of Korean patients with type 2 diabetes mellitus. METHODS: A total of 113 patients with type 2 diabetes and 123 patients with diabetic nephropathy were enrolled in this study. The Pro12Ala polymorphism of the PPAR-gamma2 gene and the Gly482Ser polymorphism in the PGC-1alpha gene were determined with the polymerase chain reaction amplification, BstU-I and Msp I enzyme digestion, and gel electrophoresis. RESULTS: The genotype and allelic frequency of PPAR-gamma2 Pro12Ala gene were not different statistically between the diabetic nephropathy and the control. The genotype of PGC-1alpha Gly482Ser in diabetic nephropathy was also not different from those in control. The allelic frequency and carriage rate of Ser allele in PGC-1alpha Gly482Ser were significantly higher in patients with diabetic nephropathy than those in control (respectively, p<0.05). CONCLUSION: The polymorphisms of the PGC-1alpha Gly482Ser gene are significantly associated with the nephropathy in Korean patients with type 2 diabetes mellitus.
