We describe an on-line dual detection method using HPLC for lipoprotein analysis that allows simultaneous determination of cholesterol and triglyceride profiles from a single injection of sample. Two different gel permeation columns, TSKgel LipopropakXL and Superose 6HR, were applied to the dual detection system, evaluating analytical performance of the(More)
To clarify the influence of chronic and excessive alcohol consumption on gustatory function, we examined taste functions of 20 male alcoholics by total oral gustometry using salty, sweet, sour, bitter and glutamate solutions. As results, all patients showed markedly impaired taste in all kinds of solutions comparing with age and sex matched healthy persons,(More)
We have developed a simple and reliable method for quantitative detection of triglycerides (TG) in serum lipoproteins and serum-free glycerol (FG) by high-performance liquid chromatography (HPLC). After separation of serum constituents using a new gel-permeation column (TSK gel Lipopropak XL, Tosoh) and a new eluent (TSK eluent LP-2, Tosoh), TG and FG were(More)
The lipid profiles of sera obtained from the adult inhabitants of a rural community with low cardiovascular mortality named Kin-cho in Okinawa were studied by the lipoprotein profiling system. The results were compared with those of the control sera obtained from healthy adults in Tokyo. Serum lipid profiles of the inhabitants in Kin-cho revealed(More)
HDL-cholesterol (HDL-C) values measured by precipitation (sodium phosphotungstate-MgCl2) and direct methods were compared with those obtained by HPLC with a new column (TSKgel Lipopropak) and an eluent (TSKeluent LP-1). The HDL-C values determined by the precipitation method were significantly (P <0.001) lower than those by the HPLC method, whereas the(More)
The activities of serum malate dehydrogenase (MDH) and its mitochondrial isoenzyme (MDHm) were studied in sera of patients with liver disease. They proved to be more useful than those of aspartate aminotransferase (AST) and its mitochondrial isoenzyme for detection of hepatocellular carcinoma and acute circulatory failure, and for estimation of the severity(More)
BACKGROUND The main purpose of this study was to evaluate the between-instrument variation of the HPLC method for the measurement of total cholesterol (TC), HDL-cholesterol (HDL-C), LDL-cholesterol (LDL-C), VLDL-cholesterol (VLDL-C), chylomicron cholesterol (CM-C), LDL size, and HDL size. Furthermore, the accuracy of the HPLC was assessed for the(More)
We fractionated normal urinary proteins obtained from 40 healthy subjects using cellulose acetate membrane electrophoresis and stained them with Acid Violet 17. The electrophoretic patterns were classified into four groups. Each of groups I, II, III, IV had an albumin peak and 1, 2, 3, and 4 additional globulin peaks, respectively. Within-day variation(More)
High density lipoprotein (HDL) is increased by exercise and drinking and is well known as a negative risk factor of coronary heart disease. We analyzed serum lipids of alcoholics from the view points of biochemical examination, remnant like particle (RLP) and particle size of lipoprotein for the purpose of estimated effect of serum lipids, especially HDL(More)
