The mechanism of vasodilation effect of GS-389, 1-(4'-methoxybenzyl)-6,7 -dimethoxy-1,2,3,4-tetrhydroisoquinoline hydrocholoride, a possible cyclic GMP specific phosphodiesterase inhibitor, on rat and mouse thoracic aorta ring has been investigated. GS-389 relaxed rat and mouse thoracic aorta precontracted with phenylephrine and high K+(60mM) in concentration dependent manner. Presence or absence of endothelium did not alter the relaxing effects of it. GS-389 inhibited Ca2+-induced contraction of the high K+ or 1 uM phenylephrine. Initial phasic contraction induced by phenylephrine and caffeine in Ca2+ free solution was inhibited by GS-389. Methylene blue pretreatment suppressed relaxation effect of GS-389. Relaxation by isoproterenol or sodium nitroprusside and by acetylcholine in endotheilium preserved aorta was potentiated by concurrentadministration of GS-389. GS-389 inhibited phenylephrine-induced phosphatidylinositide hydrolysis. It is suggested that inhibition of phosphoinositide turnover associated with elevated cyclic nucleotide by GS-389 may be the possible vascular relaxation mechanism of it.

A case of multiple myeloma combined with stomach cancer and related literatures were reviewed. A 67 year-old male patient entered the hospital with dysphagia and weight loss for 3 months. Peripheral blood examination revealed anemia with rouleaux formation. Total protein of the serum was 9.9 g/dl with hyperglobulinemia (albumin 2.7 g/dl, globulin 7.2 g/dl, A/G ratio 0.375). On the electrophoresis and immunoelectrophoresis of the serum, the abnormal protein with the pattern of monoclonal gammopathy (IgG-K type) was shown. There were multiple variable sized osteolytic lesions on skull X-ray and abnormal hot uptakes of rips on bone scan and result of rib biopsy was plasmacytoma. Gastrofiberscopy was performed to search for the cause of upper gastrointestinal bleeding, revealed stomach cancer, and the result of the gastric mucosal biopsy proved to be well-differentiated adenocarcinoma.

This study was carried out to survey the prevalence of Helicobacter pylori infection and the incidence of vacuolating toxin producing H. pylori from the gastric biopsy specimens of patients with 178 gastritis, 57 gastric ulcer, 455 gastric cancer and 44 healthy person in Pusan, Korea. Further aim of this study was to evaluate the effect of ginseng extract, sofalcone, ginsenosides (F1, Rb3, Re, Rgl), sangwha, green, arrowroot, ginger, and jujube tea on the activity and production of vacuolating toxin by H. pylori in vitro. The isolation rates of H. pylori by culture method from gastric biopsy specimens were 34.1% in healthy person, 42.1% in gastritis, 36.8% in gastric ulcer, and 39.3% in gastric cancer. The isolation rates of vacuolating toxin producing H. pylori from gastric biopsy specimens were 80% in healthy person, 82.7% in gastritis, 81% in gastric ulcer, and 83.8% in gastric cancer. The growth of H. pylori was not influenced by the addition of 10 ug/ml or 100 ug/ml of Ginseng extract and 10 ug/ml of sofalcone in the medium, but the production of vaculating toxin of H. pylori was significantly inhibited by the addition of 100 ug/ml of Ginseng extract and sofalcone. The activity of vacuolating toxin in the culture supernatant of H. pylori was significantly diminished (1/2-1/16 compared to control) by the addition of 10 mg/ml of sangwha, green, arrowroot, and ginger tea, and 1 ug/ml of ginsenosides F1, Rb3, Re, and Rgl. These results suggest that the isolation rates of vacuolating toxin producing H. pylori were significantly higher than that of the foreign reports. Ginseng extract and sofalcone have direct inhibitory effect on the activity of vacuolating toxin production by H. pylori without considerable growth inhibition and sangwha, green, arrowroot, and ginger tea have direct inhibitory effect on the activity of vacuolating toxin of H. pylori.

PURPOSE: For the purpose of using Re-188 as a therapeutic radionuclide, we performed the quality control of the W-188/Re-188 generation system. MATERIALS AND METHODS: Several quality control tests of the Re-188 eluate from generator were carried out of about 300 days. After elution of Re-188 with normal saline (20 ml), chromatogram and gamma-ray spectrum of Re-188 eluate were obtained. The presence of aluminum which was derived from the elumina bed of the generator was detected by using aluminum ion indicator kit. Re-188 eluate was allowed to decay for several days, and then W-188 breakthrough in the Re-188 eluate was measured by detecting gamma-ray at 227 keV and 290 keV. The pH and the pyrogenicity of the eluate were checked. The Re-188 eluate from the generator was 67.4+/-7.0% of W-188 during 270 days, and it was hightest at third day after previous elution. Radiochemical purity of Re-188 eluate obtained from chromatogram was higher than 99%. Gamma-ray spectrum of Re-188 eluate showed a peak at 155 keV. Aluminum ion and W-188 contamination were not detected. The pH of Re-188 eluate was 3 and the concentration yield was 85%. CONCLUSION: Our experiments and results on quality control tests of Re-188 eluate from W-188/Re-188 generator may be useful for setting W-188/Re-188 generator in hospitals.

Pure red cell aplasia in uncommon disorder characterized by finding of anemia, absence of nucleated red blood cell in the marrow, absence of reticulocytes in the peripheral blood and normal peripheral platelet and leukocytes counts. We experienced one case of pure red cell aplasia associated with hemolytic anemia characterized by hemoglobinuria, reticulocytopenia, and erythroid hypoplasia of the bone marrow. The cause of the illness was not definitely identified, but we concluded that this patient had simultaneous occurrence of PRCA and hemolytic anemia following administration of diphenylhydantoin after craniotomy rather than virus or bacteria induced. The simultaneous occurrence of PRCA and hemolytic anemia in uncommon and the mechanism for diphenylhydantoin induced PRCA and hemolytic anemia is unclear.
