Obstruction on the urinary tract eventually results in damage to the kidneys and loss of function. The questions that concern the clinician are the degree of nephron loss in that kidney and the potential for recovery following the relief of obstruction. 99mTc DMSA accumulates in tubule cells and has been proposed as a marker of the tubular mass. The authors estimated the renal uptake ratio of 99mTc DMSA for the degree of nephron loss corresponding to duration of hydronephrosis following left ureteral ligation in 5 NewZealand white rabbits and the potential for recovery following percutaneous nephrostomy of hydronephrosis in 24 rabbits. While the renal uptake ratio of 99mTc DMSA of the kidney with unilateral hydronephrosis following ureteral ligation reduced dramatically within 24 hour, that of the opposite healthy kidney increased, and the total renal uptake ratio was same as normal functioning kidneys before ureteral ligation. Upon ureteral release, there was no evidence of definite recovery or impairment in the experimental kidneys for 5 days. The authors conclude that a combination of ureteral release and administration of some drugs such as renal vasodilator or diuretics is an appropriate treatment for the recovery of function in unilateral hydronephrosis.

BACKGROUND: Microalbuminuria is the main parameter used in diabetic patients for clinical evaluation of early diabetic nephropathy and other complications. The most common method for quantitative urinary protein relies on a 24-hour urine collection or overnight urine collection; however, this method is time consuming and sometimes obtains inaccurate results. This study is aimed to test whether the microalbumin to creatinine ratio (Uma/Ucr) in the first-morning urine samples correlates with the microalbumin content in the 24-hour urine collection. METHODS: 59 urine samples from 59 type 2 diabetic patients were analyzed for Uma/Ucr, and for 24-hour urine microalbumin that were successively collected. RESULTS: Daily microalbumin excretion varied from 2.4 to 168.7 mg/24 hr with a median value of 22.9 mg, and Uma/Ucr ranged from 3.4 to 200 g/mg with a median value of 29.0 g/mg. An excellent correlation was found between the microalbumin excretion measured from the 24-hour urine collections and the first-morning urine Uma/Ucr ratio (R=0.93, P<0.001). All patients that excreted more than 30 mg albumin in the 24-hour urine samples also had an Uma/Ucr of more than 30 g/mg. Patients who had less than 30 g/mg of Uma/Ucr were unlikely candidates for microalbuminuria. CONCLUSIONS: This study indicates that measurements of Uma/Ucr in first-morning urine samples are a simple and reliable alternative to measurements of the urinary albumin excretion rate in the 24-hour urine collections.

Anti-M antibodies are usually assumed to be naturally occurring and to consist of immunoglobulin M reacting at 4degrees C. They are not usually considered to be clinically significant, however, many of them have an immunoglobulin G component reacting at 37degrees C and can be correlated with hemolytic disease of the newborn (HDN). We report a moderate case of HDN by anti-M. A 2-days old baby born from a mother with preeclampsia as a second pregnancy was admitted due to anemia, hyperbilirubinemia and hypoxic encephalopathy. The blood type of mother was AB, ccDEE, NN, and the blood type of baby was A, D+, and MN. Antibody screening and identification identified anti-M antibody which was strong reactive at 37degrees C albumin and antiglobulin phase in both baby's and her mother's serum. The direct antiglobulin test of baby's red blood cells was negative. The infant was transfused with group O red cells which have negative to trace reaction with her mother's serum in antiglobulin phase. Two days later, the hemoglobin level elevated from 6.7 g/dL to 15.9 g/dL falled to below 11 g/dL quite soon. After all, newborn died of cardiac arrest due to her basic disease at age of 49 days; metabolic acidosis and hypernatremia.

The introduction of a new, fully automated system into the clinical microbiology laboratory contributes to a rapid identification of microorganisms with accurate and reliable results, but such a system requires a high cost and additional tests for identification of some species. For instance, additional tests on oxidase, indole, motility, hemolysis, and pigmentation are needed in the correct identification by using Vitek GNI+ system (bioMerieux Vitek Inc., MO, USA). In particular, Vibrio and Aeromonas species are occasionally identified incorrectly when an automated system is used, and thus conventional biochemical tests may be more reliable in the identification of such species. We experienced three cases of incorrect identification of Vibrio parahaemolyticus, Vibrio cholerae, and Aeromonas veronii biovar sobria as Vibrio alginolyticus by using Vitek GNI+ card.

BACKGROUND: Oral allergy syndrome(OAS) is composed of it,ching sense and edema in oral cavity, lips, throat, pharynx, and larynx following eating some fresh fruits or vegetables. It has been known that most of patients with OAS are allergic to pollens. Common epitopes were found among pollens, fruits and vegetables. Although OAS is a common farm of food allergy in adults, this is the first epidemiologic study of OAS in Korea. MATERIAL AND METHOD: One hundred and fifty one patients who showed positive skin reaction to pollens were telephone-interviewed. Investigation of the prevalence and clinical manifestations of OAS was possible in 81 patients. RESULT: The prevalence of OAS among these patients was 34.6% (28/81). OAS was found in 24(48%) out of 50 patients sensitized to tree pollens, whereas 4(13%) of 31 grass or weed pollen-sensitized paients had OAS. Most common causative food was apple and all of 17 apple- OAS patients were sensitized to tree pollens. Peach was the second common food and 14 of 15 peach-OAS patients were sensitized to tree pollens. Besides oral symptoms, rhinitis, asthma, diarrhea, nausea, vomiting or generalized urticaria were accompanied in half of the OAS patients (14/28). Some patients showed OAS to some unique Korean foods such as dropwort, taro and Aster. CONCLUSION: OAS was very common in pollen-sensitized patients. Larger epidemiologic studies are needed to find unique Korean foods and their antigensm causing OAS.

STUDY DESIGN: Literature review. OBJECTIVES: The aim of this study was to present updated information on the research support programs offered by the National Research Foundation of Korea. SUMMARY OF LITERATURE REVIEW: The research support programs offered by the National Research Foundation of Korea are an important cornerstone for obtaining other grants from the government and commercial companies. However, no information has yet been provided in the literature about these programs. MATERIALS AND METHODS: Review of the relevant literature. RESULTS: The research support programs offered by the National Research Foundation of Korea are complex. However, it is possible to find appropriate grants. It is necessary to focus on the individual basic research program. CONCLUSIONS: Novel proposals have a greater chance of receiving funding, especially if the appropriate background and preliminary data are provided.
