Urine Specific gravity와 Osmolality에 관한 검토

Specific gravity of the urine and the measurement of osmolality have been utilized for renal function tests. Specific gravity of urine is influenced by molecular weight and its character, but osmotic pressure is not influenced by those. So that, we think the measurement of osmotic pressure is more reliable test than specific gravity in renal concentration test. So, we recommend the measurement of osmotic pressure instead of specific gravity in clinical laboratory. The comparative results of specific gravity and osmolality showed as Table 2 and Fig. 1 and 2.

Blood levels of lipids (Apo A1, Apo B, HDLCholesterol, Triglycerides, and Total cholesterol) were determinated in elderly men and women for their health examination. These data may be useful in the investigating of cardiovascular diseases which ar~ a major cause of death in this age group in Korea.
동결(凍結)을 리용(利用)한 체액단백액(體液蛋白液)의 농축법(濃縮法)

When body fluid containing protein or other electrolytes is frozen, we find that the fluid is separated upper thin layer portion and lower thick layer portion. The lower thick layer portion often contains plenty protein and electrolytes. If the urine and other body fluid are frozen in the chamber of -16 to -20℃, and thawed in the test tube, the specimens on the bottom of test tubes remain concentrated protein and solutes. The specimens of concentrated by frozen and dialyzed, were performed the test of agarose gel electrophoresis for protein and the results were compared each other. The results of those are Table 4, and case 1 to 7 are relatively good correlation, and case 8 to 13 are relatively poor correlation. But, generally speaking, the means of those data are good relations.

The Seoul Clinical Laboratories(SCL), a branch of the Seoul Medical Science Institute undertook CBC examination on l, 039 male and 527 female healthy individuals from May 1st. through July 31 th. 1991. Coulter S-Plus II was used for CBC and the data was handled with modified statistical method by SAS PC program. 13 parameters of CBC of both male and female groups were separately studied. The majority of items were comparable to the normal distribution pattern. However, some items were not in accord with normal pattern. There were minimal difference between data treated with Mean± 2SD and non parametric method. Among 13 items, Hb, Hct, platelets were slightly higher than many previously published data and other items are almost identical. There seems to be ahead for better scientific approach to handle statistics utilizing ever improving software program and continuous studies on normal data.

RIA has been used to measure accurately a minute quantity of Ags, such as proteins. hormones, enzymes or drugs. However, due to the presence of a radication hazard and the increment of having to pool test specimens. RIA is gradually being replaced by other immunoassay that have a comparable sensitivity but do not require radiocative meterial. Turbidimetric immunoassay, latex immunoassay and fluorescence immunoassay are such examples. We at the department of clinical pathology, Asan medical center, compared CH 50 activity with C3 , C4 quantity by nephelometric method.

A study was performed to compare an agarose gel electrophoresis for the protein fraction with the other reported reference values. It was carried out to determine the reference values of adults in Seoul area, from Oct. 1st 1991 through Oct. 20th 1991. 143 male and 87 female venous blood sampl- es were collected from SCL personnel and collected analized by the agarose gel electrophoresis at the Seoul Clinical Laboratory of Seoul Medical Science Institute. The results are shown on Table 2 and 3. Our results show that albumin was 2. 4% lower and .,-globulin was 4. 5% higher compared with the Corning report in the U.S. A., whereas our results were virtually equal to previously reported results of rural population in Korea. The increase- d y-globulin albeit small, may indicate more prevalent chronic infection among Korea populati on.
