BACKGROUND: As more than 80% of Korean hospital laboratories don't use glycerol blank for the triglyceride measurement, we investigated free glycerol interference on the measurement of triglyceride concentration. METHODS: We collected 237 specimens which had more than 300mg/dL of triglyceride measured by Abbott (without glycerol blank, USA) reagent from the 217 patients visiting Catholic University Hospital of Taegu Hyosung from September, 1995, to May, 1996. We retested them with Youngdong (without glycerol blank, Korea) reagent, and IRC reagent (with glycerol blank, Japan), and also measured free glycerol concentration with Youngdong reagent. Then we examined the clinical records of the patient showing increased glycerol concentration. RESULTS: Average triglyceride concentration measured by Abbott reagent was 448.0+/- 165.9 mg/dL and average glycerol interference to triglyceride concentration was 3.4+/- 6.7%, There were 8 patients (3.4%) who revealed more than 10 % of glycerol interference. Except these patients the average glycerol interference was 2.4+/- 1.4%. Among these 8 patients, 3 patients were treated with Frucenil and other 3 were with Intralipose(R), and the other 2 were diagnosed as diabetes and preeclampsia respectively. In vitro test, Frucenil mixed with serum in 1% (v/v) increased triglyceride concentration as high as 640.6% with Abbott reagent, but it did only 48.4% with IRC reagent. CONCLUSIONS: Triglyceride measurement by non glycerol blank method exceeded the recommended limit of National Cholesterol Education Program's precision, and this method extremely overestimated the triglyceride concentration for the patient with the glycerol containing fluid therapy. So all laboratories would be encouraged to use the glycerol blank method for triglyceride measurements.

The purpose of this study was to investigate the inhibitory role of vitamin A with respect to activation of Ito cells in fibrosis of the rat liver induced by common bile duct ligation(CBDL). The liver was examined by immunohistochemical staining for a-smooth muscle actin,the known marker of activated Ito cells, and light and electron microscopy after CBDL andCBDL with intraperitoneal injection of retinoic acid (Sigma, USA) 1 mg/Kg in 3 times per week. The results were sumrrlerized as follows: After CBDL, the bile ductules were markedly proliferated in the periportal areas extending toterminal hepatic veins. Interstitial fibrosis and inflammatory cell infiltration appeared, however,cholestasis was minimal. Retinoic acid treatment with CBDL decreased bile ductular proliferationand interstitial fibrosis compared to CBDL only. After CBDL, proliferated and activated Ito ceIs showing positive reaction in smooth muscle actin were present in the periductular andperisinusoidal areas, and areas of increased interstitial fibrosis. Activated ito cells weredecreased in number after CBDL with vitamin A treatment. Electron microscopically,intracytoplasmic fat droplets and the cytoplasmic processes of Ito cells were decreased afterCBDL. Myofibroblasts were frequently appeared in the interstitial fibrosis after CBDL. But,intracytoplasmic fat droplets of Ito cells were well preserved, and myofibroblasts were found lessfrequently after CBDL with vitamin A treatment. The results suggest that vitamin A plays an inbitory role in the activation and fibrogenesis ofIto cells after CBDL.

Helicobacter pylori(H. pylori) infection is considered the most important cause of chronic active gastritis and peptic ulcer. To determine the prevalence, distribution and it's relationship to degree of inflammation, gastric biopsy specimens were obtained from 331 nonulcer dyspepsia(NUD) patients consisting of 52 H. pylori negative normal volunteers and 279 H. pylori infected patients. Lymphoid follicles, degree of acute and chronic inflammation(Grade 0 to 3), and degree of H. pylori(Grade 0 to 4) were observed. The prevalence of H. pylori in NUD was 84.29%. The lymphoid follicles were found in 138 patients(41.7%) and only 5 patients(l.5%) without H. pylori showed lymphoid follicles. There was strong a relationship between lymphoid follicles and degree of acute and chronic inflammation and intensity of H. pylori infection(P<0.001). Acute and chronic inflammation were more serious in the antrum than body in H. pylori infected patients. There was no relationship between lymphoid follicles and the site in the stomach of H. pylori infection(P<0.078), but the body portion had an increased frequency of lymphoid follicles compared to the in antrum. Our results indicate that the prevalence of H. pylori infection in Korea is higher than in Western people and the degree of acute and chronic inflammation are strongly correlated with the presence of lymphoid follicles. The lymphoid follicles are believed to be absent from the normal stomach and their presence is strongly associated with H. pylori infection. The fact there is an that increased frequency of lymphoid follicles in H. pylori infected patients, and that they are more prevalent in the body of the antrum, support the concept that H. pylori may be a precursor in the development of primary gastric lymphoma.

The athors have presented recently treated 4 cases of malignant tumors of the eye and adnexa. 1. All of them were rapidly aggrevated after previous incompleted surgical management (3 cases) or postponement 01 operation (1 case). 2. Three cases of them except adenoid cystic Ca. were recurred after orbital exenteration. 3. The authors were concluded that the poor prognosis is due to its nature of malignancy and delayed radical surgical management.

Authors experienced a 59-year-old male patient with the lymphoma of the small iritestine which involved the adjoining mesenteric lymph nodes, the parietaI pleura, and the skin. The skin lesions, simulating necrotizing angiitis, were deep purple colored, asymptomatic, tense, hemorrhagic bullae with soft consistency on the both thighs and left infraorbital area. He had extranodal type, and diffuse, poorly differentiated lymphocytic lymphoma by the Rappaport classification, and stage IV by the Ann Arbor staging classification. After about 50 days of clinical manifestations, he was died mainly due to massive intestinal bleeding.

The ectomycorrhizal roots were collected from the soils around the bases of basidiocarps of the four edible mushrooms in the stands of Pinus densiflora or Querus acutissima communities (Mt. Wol-Ak in Eastern Chung-Puk): The basidiocarps of Tricholoma matsutake (TM), Sarcodon asparatus (SA), S. imbricatum (SI), and Polyozellus multiplex (PM) are usually collected. The ectomycorrhizal roots of TM, PM and SI were related to the roots of P. densiflora, but the other to the roots of Q. acutissima in Korea. Particularly, the basidiocarps of PM were collected in the mixed stand of both P. densiflora and Q. acutissima. The morphologies of the ectomycorrhizal roots were observed to be the yellowish brown coral (dichromatous) or pyramid types in the roots of the pine, but dark brown un-branched sticks (roots) in the ends of ectomycorrhizal roots of Querus plants. The un-branched roots were covered with the dark mycelia (rhizomorph) around them. Therefore, the ectomyorrhizal roots of PM were observed to have two kinds of types; The single blackish un-branched roots were observed to be attached to the yellowish coral type roots. The bundles of TM mycelia were filled with cortical cells (in the roots of P. densiflora), but the mycelia of the other fungi (Aphylloporales) were massed between the cortical cells of P. densiflora or Q. acutissima. Their anatomical and gross features were considered to be simailar but very important in the ectomycorrhizal roots for these edible mushrooms.
