The evaluation of patients with microscopic hematuria after blunt abdominal trauma has become controversial. We tested the hypothesis that renal contusion can be diagnosed clinically and that these patients do not require radiographic evaluation. To evaluate the association of microscopic hematuria without shock and with renal injury, we reviewed the medical records of 252 patients following blunt abdominal trauma. Microscopic hematuria without shock was noted in 58 of 252 patients. Of the 58 patients 52 had renal contusion, 4 had renal laceration, 1 had a renal rupture and 1 had renal pedicle injury. All of the patients with renal contusions experienced no complications from nonoperative management. But, avoiding a radiopraphic evaluation in patients with blunt renal trauma plus microscopic hematuria and no shock would miss a few cases of severe renal injury.

This research centered on seasonal analysis for the concentration of heavy metals in 5 sites within Taejon 3rd and 4th industrial Complexes. Total suspended particulates were collected on glass microfibre filters (Whatman EPM 2000) by high volume air samplers. About 20 metal elements including 13 toxic ones were analyzed by ICP-MS and ICP-AES after the pretreatment of mixed acid extraction. The following results were summarized from the research : 1) the concentrations of TSPs were 17.7∼219.6㎍/㎥ while the arithmetic mean concentration was 101.7㎍/㎥ ; 2) the arithmetic mean concentration of human carcinogen such as arsenic, hexavalent chromium and nickel subsulfide was 9.99, 6.68 and 6.13 ng/㎥ while that of probable human carcinogen such as beryllium, cadmium and lead was 0.12, 3.37, 97.65 ng/㎥, respectively.

In this study The auther set casting mold degree on 500℃ 700℃ 900℃ and carried out centrifugal casting about Ticonium premium 100 which is Ni-Cr alloy and widely used as dental non-precions alloy. The outhor measured tensile strength and abserved fine structure by microscope and obtained following conclasions: 1. The tensile strength was 457.9±21.7 /kg/mm2 in 500℃ casting mold degree. 412.3+19.6kg/㎟ in 700℃ casting mold degree and 398.3±26.5kg/x-㎟ in 900℃casting mold degree. The tensile strength was reduced when the casting mold degree increased. 2. In all casting mold degree resinous structure-the typical casting structure-was formed and fine air bubble casting defect was appeared. 3. When casting mold temperature increased resinous crstal was appeard coarsely and largely.

The possibility that liver and kidney function is adversely affected by current levels of environmental exposure to cadmium (Cd) as investigated in adult men and women in the general population in Seoul. From February to August in 2001, blood and morning spot urine samples were collected from 136 not occupationally exposed group (age range 20~75 years) at 4 survey sites throughout Seoul. Liver and kidney function parameters in serum and urine were examined by conventional methods. The questionnaire included factors, i.e. sex, age, smoking, alcohol, diet habit etc. The geometric mean values for Cd in blood (Cd-B) were 1.43 μg/l. It seemed prudent to conclude that liver and kidney function as not disturbed by the current environmental exposure to Cd in study.

Effect of .Mume Fructus on intestinal function was investigated in rabbit, making use of its water extract. Mume Fructus water extract(MWE), of small doses(0.1, 0.3㎎/ml) produced contractile action but did not effect the spontaneous movement strips of high dose(1.0㎎/ml) elicited relaxative action and the inhibition of spontaneous movement in ileum strips. In lieum strips, MWE did not influence the contractile action but augmented the spontaneous movement to acetylcholine, MWE elicited the inhibition of contractile action and the agumentation of spontaneous movement to pilocarpine, MWE inhibited the both actions to histamine, did not affect to serotonin and blocked to dopamine. MWE exhibited the relaxation and the inhibition of spontaneous movement in longitadinal muscle of colon. In longitudinal muscle of colon, MWE inhibited both actions to acetylcholine, did not influence the contractile actions but augmented the spontaneous movement to histamine and serotonin. MWE elicited the increase of contractile actions and the decrease of spontaneous movement in circular muscle of colon. In circular muscle of colon, MWE augmented both actions to acetylcholine, inhibited both actions to serotonin, and then did not affect the contractile action but augmented the spontaneous movement to histamine.

Objectives:The purpose of this study was to describe the status of mental activity participation in community-dwelling elderly and to evaluate the association between mental activity and cognitive function after adjustment for depression and anxiety. Methods:This study was based on the Suwon Project, which was a cohort comprising of nonrandom convenience samples of ethnic Koreans aged 60 years and above. All the subjects completed the study questionnaire including their demographic characteristics, current and past illnesses history, drug history, Korean version-Mini Mental State Examination (K-MMSE), Korean version of Short Form Geriatric Depression Scale (SGDS-K), Beck Anxiety Inventory (BAI). We checked how many hours per day are used for each items of 11 mental activities through the checklist. Results:Total time spent in 11 mental activities was 237.4±152.4 minutes per day. On multiple regression analysis, total time spent in 11 mental activities (MA-total), and time spent by watching television and reading book/newspaper showed statistically significant association with K-MMSE score after adjustment with age, sex, education, chronic medical illness, depression and anxiety. Conclusion:Our result suggested that mental activity may be associated with cognitive function in the elderly without cognitive impairment in the community after adjusting age, sex, education, chronic medical illness, depression and anxiety.
Anti-JC virus antibodies in rituximab-treated patients with neuromyelitis optica spectrum disorder.

<P>Rituximab, a chimeric monoclonal anti-CD20 antibody, has been proposed to be effective for neuromyelitis optica spectrum disorder (NMOSD). A concern for developing progressive multifocal leukoencephalopathy (PML), which is caused by John Cunningham virus (JCV), has been suggested particularly in patients treated long term with rituximab. In this study, using a modified enzyme-linked immunosorbent assay with glutathione S-transferase-tagged VP1 as the antigen, we investigated the seroprevalence of anti-JCV antibodies among 78 Korean patients with NMOSD and the change in anti-JCV antibody serostatus following long-term rituximab treatment. The overall seroprevalence of anti-JCV antibodies was 69 % prior to rituximab administration. Over a mean of 4 years of repeated treatment with rituximab, no patient developed PML. Of 24 initially seronegative patients, none converted into seropositive, whereas six (11 %) of 54 initially seropositive patients converted into seronegative. Our results might support the safety of long-term rituximab treatment in patients with NMOSD with regard to the risk of developing PML.</P>
