Renal scarring associated with vesico-ureteral reflux(VUR) is one of the major causes of end stage renal failure and renal hypertension in children. Urinary ${\beta}_2$-microglobulin(MG) has been suggested as a potential marker for presence of renal tubular damage. This study was designed to evaluate the significance of random urine ${\beta}_2$-MG as a predictor of presence of vesico-ureteral reflux in children with urinary tract infection(UTI). 57 children with urinary tract infection were studied. Patients were devided into two groups; 35($78.9\%$) children have UTI without VUR and 12($21.1\%$) children have UTI and VUR. Beta2-MG and creatinine in random urine sample was measured to decide the excretion ratio(${\beta}_2$-MG/creatinine). Among the 57 children with UTI, 44 children were confirmed by urine culture study and 13 children suspected by compatible clinical feature. Random urine ${\beta}_2$-MG of VUR group ($2.2{\pm}5.91$ mg/L) were significantly higher than that of simple UTI group($0.19{\pm}0.16mg/L$)(P=0.03). The ${\beta}_2$-MG/creatinine ratio of VUR group($32.41{\pm}25.7$) were significantly higher than that of simple UTI group($3.93{\pm}3.44$)(P=0.007). In conclusion, random urine ${\beta}_2$-MG and excretion ratio deserved early predictor of presence of VUR in children with UTI. And this method was more simple and inexpensive than the method of measuring ${\beta}_2$-MG with 24 hour urine collection, so might be a useful screening test for VUR in children with UTI.

Background: Cervical cancer is the second commonest cancer among Indian women and its association with human papilloma virus (HPV) is well established. This preventable cancer accounts for the maximum number of cancer related deaths among rural Indian women. Unlike in developed countries there are no organized cervical cancer screening programmes in India due to lack of resources and manpower. Objective: To detect genital HPV infection using urine samples among asymptomatic rural women in the age group of 18-65 years. Materials and Methods: The study area chosen was Perdoor village in Udupi Taluk, Karnataka State and all the women in the age group of 18-65 years formed the study cohort. A cross sectional study was conducted by house visits and 1,305 women were enrolled in the study. After taking written informed consent a data sheet was filled and early stream random urine samples were collected, transported to a laboratory at 4OC and aliquoted. Samples were tested using nested HPV PCR with PGMY09/11 and GP5+/6+ primers. Positive cases were genotyped by sequence analysis. Results: Study participants included 1,134 sexually active and 171 unmarried women with a mean age at marriage of 22.1 (SD=3.9) years. Study area showed high female literacy rate of 86.6%. Five urine samples tested positive for HPV DNA (0.4%). Conclusions: We found very low genital HPV infection rate among women from monogamous community. This is the first major population based study carried out among asymptomatic rural women to detect genital HPV infectio from Karnataka using urine samples.

This study was conducted to evaluate the health hazards and to develop early diagnostic methods of the manganism in experienced welders and to know the meaning of signal intensities on the brain Magnetic Resonance images. It was carried out from December 1996 to february 1997 with 277 male welders, the duration of welding was at least 5 years or more. The study was consisted of a questionnaire, physical examination and measurements of blood & urine manganese concentrations. Brain Magnetic Resonance imaging was done on 19 study subjects by random sampling. As the duration of welding increases, the positive rates of clinical symptoms, neurological examinations and blood manganese concentrations were also increased. However, physical examinations and urine manganese concentrations were not statistically significant with the duration of welding. Authors couldn't observe any Parkinsonism-like diseases. There were statistically significant correlations between duration of welding and blood manganese concentration(r=0.16, p<0.01). There were not statistically significant correlations between duration of welding and urine manganese concentrations (r=0.06). There were statistically significant correlations between blood & urine manganese concentration(r=0.34, p<0.01). By viewing brain Magnetic Resonance images, 13 welders(68.4 %) among 19 welders were found to have signal intensities. The positive rates of clinical symptoms, physical examinations, neurological examinations and blood & urine manganese concentrations were not statistically different between those with signal intensities and those without signal intensities. We would like to suggest that some non-specific clinical symptoms and neurological signs are correlated with the duration of welding but any Parkinsonism-like diseases had not been observed with these welders. Next we suggest that the high signal intensities on TlWI of brain Magnetic Resonance images are not the sign of manganese intoxication but the sign of manganese deposition.

The diagnostic method was, evaluated in experimentally induced acute renal failure in doges. Ten male dogs weighing from 5 to 10 kg were assigned to two groups(gentamicin & ethylene glycol treated group) al random. Gentamicin sulfate at 10 mg/kg of body weight, t.i.d., for 7 days and ethylene glycol at 3 ml/kg of body weight once used in a randomized complete block design with tee treatments in block. The samples(blood, urine) were collected before and 1,3,5,7,9 and l1th day after administration. The serum creatinine concentration and BUN(blood urea nitrogen) were sig- nificantly increased at the 7th day than before administration in gentamicin treated group (p<0.05), bolt there was significant increase at the 1st day than before administration in ethylene glycol treated group(p<0.05). The urine GGT(gramma glutamyl transpeptidase) and GGT/creatinine were significantly increased at the 1st (lay after administration in gentamicin treated group (p<0.05). But in ethylene glycol treated group, there was no significant changes. The value of FENa (fractional excretion of sodium) was significantly increased at the 3rd day after administration in gentamicin treated group and the 1 st day after administration in ethylene glycol treated group (p<0.05). These results suggest that FENa was a good parameter of renal function in dogs with acute renal failure.

The total number of clinical materials collected from Dec 1, 2005 to Nov 30, 2006 in C. hospital was 63,133. Among these materials, the isolation of Staphylococcus spp. was 5,252 strains. The proportions of Staphylococcus species infection were as follows ; 46.7% in S. aureus, 39.3% in S. epidermidis, 4.7% in S. hominis, 3.8% in S. haemolyticus, 2.9% in S. capitis and 2.5% in others. Seventeen strains of Staphylococcus species were identified with an isolation range of 0.02-46.7%. The isolation ratios of Staphylococcus species were 7.8% (2,134/27,362) in female, 8.7% (3,118/35,807) in male and 8.3% (5,252/63,133) in both. The age-related frequencies of Staphylococcus species were 22.1% in the 60-69 year group, 19.3% in the 70-79 year group and 17.1% in the 50-59 year group. The isolation ratio of the 0-49 year group to the 50-over 80 year group were 1.74 times in female, 1.92 in male and 1.85 in both. The isolation frequency of Staphylococcus spp. was at its highest in April (9.9%) and at its lowest in February (6.8%) according to monthly analysis. According to seasonal variation, the isolation frequencies of Staphylococcus spp. were 27.0% in Summer, 25.9% in Spring, 23.9% in Fall and 23.2% in Winter. The clinical departments showing over 9% isolation rate against Staphylococcus spp. were critical care medicine (12.9%), department of pediatrics (11.6%), department of urology (9.8%) and department of neuro-surgery (9.1%). On the other hand, the lowest number was observed in the department of family medicine. The clinical material showing over 15% isolation rate against Staphylococcus spp. were 32.1% in urine (random urine and catheterized urine), 20.6% in blood and 16.0% in sputum.

Objectives : Cotinine, the major metabolite of nicotine, is a useful marker of exposure to tobacco smoke and self-reporting of smoking status is thought not to be reliable. This study aimed to evaluate the agreement between the smoking self-report among adolescents and the urinary cotinine test. Methods : The study subjects were 1226 middle and high school students in Hanam city, who were selected by stratified random sampling. The self-report about smoking behavior was compared with urine cotinine value measured with PBM $AccuSign^{\circledR}fi$ Nicotine(Princeton BioMeditech Corporation, USA). The percentage agreement, kappa and 95% confidence interval(CI) were calculated. Results : The overall percentage agreement was 88.6%, and those for boys, girls, middle school, general school and vocational school students were 87.3%, 90.1%, 93.7%, 85,5%, 90.7%, and 78.4%, respectively. The overall kappa index was 0.46(95% CI=0.39-0.54)for overall, .and those for boys, girls, middle school, general school and vocational school students were 0.56(95% CI=0.48-0.65), 0.20(95% CI=0.07-0.32), 0.21(95% CI=0.09-0.34), 0.55(95% CI=0.47-0.64), 0.42(95% CI=0.33-0.52), and 0.48(95% CI=0.36-0.60), respectively. Conclusion : The percentage agreement was relatively high but the kappa values very low for girls, and middle school students. Though the prevalence bias can be influenced by these results, the self-report was not a sufficient tool for the evaluation of adolescents' smoking status, especially in girls or middle school students.

This study was conducted to evaluate changes in plasma concentration and urinary excretion of carnitine, as well as plasma lipid level and fatty acid composition, caused by short term supplementation of carnitine in humans. Ten healthy male subjects (21.2 $\pm$ 0.5 years old) received oral carnitine supplementation (4 g/day) as tablets for two weeks. Fasting blood and random urine samples were collected from each subject both prior to and at the end of carnitine supplemention program. Following the 2 weeks of carnitine supplementation, plasma total carnitine (TCNE) concentration increased 20% (85.1 $\pm$ 7.4 vs 67.3 $\pm$ 9.1 $\mu$ mol/1, p> 0.05), while urinary excretion of total carnitine increased ten times compared to the value measured prior to the supplementation (3051 $\pm$ 692 vs 278 $\pm$ 90.1 $\mu$ mol/g creatinine, p < 0.01). Non-esterified carnitine (NEC) comprised from 71 to 88% of TCNE in plasma, and from 32 to 40% of TCNE excreted in the urine. Two weeks of carnitine supplementation in healthy adults significantly elevated plasma level of acid soluble acylcarnitine (ASAC) which is esterified mostly with short chain fatty acids (21.6 $\pm$ 1.6 $\mu$ mol/l) compared to the value measured prior to the supplementation (6.4 $\pm$ 0.8 $\mu$ mol/l) (p < 0.05). Carnitine supplementation significantly increased plasma HDL-cholesterol level (p < 0.05), and decreased the atherogenic index (p < 0.05), but failed to cause any significant change in plasma levels of total cholesterol, triglyceride, and free fatty acids. Plasma triglyceride and phospholipid fatty acid compositions were not significaly affected as well by the oral supplementation of carnitine in subjects with normal range of blood lipid levels.

A total of 1,780 isolates of Enterococcus spp. were isolated from 63,133 clinical specimens from Dec 1, 2005 to Nov 1, 2006 in "C" hospital. Isolation frequencies of Enterococcus spp. were 50.9% for E. faecalis, 41.7% for E. faecium, and 7.4% for other Enterococcus spp. containing E. avium, E. gallinarum, E. casseliflavus, E. durans, E. hirae, and E. raffinosus. There were no significant difference between gender, but according to the age group analysis, Enterococcus spp. were more frequently isolated in patients over 50 years old (20.0~24.6%) than those isolated from the patients under the age of 0~49 (1.3~9.4%). In monthly analysis, Enterococcus spp. were the most frequently isolated in April (11.9%), but presented at lowest frequency in February (5.2%). Seasonal analysis did not show a significant difference. Over half of enterococci were isolated from random urine (44.9%) and catherterized urine (15.7%). Frequencies of vancomycin resistant E. faecalis and E. faecium were 0.1% and 31.0%, respectively. Teicoplanin resistant Enterococcus was 13.3% in E. faecalis, 17.6 % in E. faecium. The Enterococcus species showing over 80% susceptibility against antimicrobial agents were E. faecalis, E. durans and E. hirae in vancomycin; E. faecalis, E. gallinarum, E. casseliflavus, E. durans and E. hirae in ampicillin. The antimicrobial agent showing susceptibility against whole group of Enterococcus species was only linezolid (95.9%), and a selection of antimicrobial agent is necessary to do essential performance identification and susceptibility tests.

Objective: This study was conducted to evaluate the use of Megasphaera elsdenii (M. elsdenii) as a probiotic on rumen fermentation, production performance, carcass traits and health of ruminants by integrating data from various related studies using meta-analysis. Methods: A total of 32 studies (consisted of 136 data points) were obtained and integrated into a database. The parameters integrated were fermentation products, rumen microbes, production performance, carcass quality, animal health, blood and urine metabolites. Statistical analysis of the compiled database used a mixed model methodology. Different studies were considered random effects, while M. elsdenii supplementation doses were considered fixed effects. p-values and the Akaike information criterion were employed as model statistics. The model was deemed significant at p<0.05 or had a tendency to be significant when p-value between 0.05<p<0.10. Results: Supplementation with M. elsdenii increased (p<0.05) some proportion of fermented rumen products such as propionate, butyrate, isobutyrate, and valerate, and significantly reduced (p<0.05) lactic acid concentration, acetate proportion, total bacterial population and methane emission. Furthermore, the probiotic supplementation enhanced (p<0.05) livestock production performance, especially in the average daily gain and body condition score. Regarding the carcass quality, hot carcass weight and carcass gain were elevated (p< 0.05) due to the M. elsdenii supplementation. Animal health also showed improvement as indicated by the lower (p<0.05) diarrhoea and bloat incidences as well as the liver abscess. However, M. elsdenii supplementation had negligible effects on blood and urine metabolites of ruminants. Conclusion: Supplementation of M. elsdenii is capable of decreasing ruminal lactic acid concentration, enhancing rumen health, elevating some favourable rumen fermentation products, and in turn, increasing production performance of ruminants.

A total of 167,955 microorganisms were isolated from 366,661 clinical specimens. Among them, 6,517 strains of the Candida spp. were isolated from the department of laboratory medicine in "C" hospital from Jan. 1, 2005 to Dec. 31, 2009. All clinical specimens were reviewed by the medical records of patients with Candida by the method of retrospectiveness. From this, we got the some isolated pure cultured yeasts. We identified these yeast by the identification kit system of VITEKII and VITEKII-ID-YST card. The isolation frequencies of Candida spp. were as follows. 56.4%,of C. albicans, 17.7% C tropicalis, 10.7% C glabrata and 9.5% C parapsilosis. The isolated frequency of Candida spp. in 2009 was 1.9 times higher than that in 2005. The clinical materials showing over 10.0% isolation rate were in sputum (30.1%), random urine (25.0%), 15.8% blood (15.8%) and catheterized urine (13.5%) in Candida spp.. The clinical department of showing over 7.0% isolation rate were in pulmonary medicine (20.5%), renal medicine (11.0%), infection disease medicine (10.4%), critical care medicine (10.0%), hematooncology (9.6%), general surgery (7.5%) and gastrointestinal medicine (7.4%) in Candida spp.. In monthly analysis, Candida spp. were most friquency isolated in July (10.6%), but lowest one in February (6.1%). Candida spp. were most frequently isolated in patient of over 50 years old (16.7-40.1%) than those isolated from the patients under the age of 0-49 (1.3-7.5%).
