We investigated the use of a diode array detector in conjunction with isocratic cation-exchange liquid chromatography for detection of organic acids in urine. The spectra and retention times of abnormal peaks found on chromatography of urine from patients with methylmalonic aciduria, maple syrup urine disease, and lactic aciduria were recorded and compared with those obtained for group of pure ...

Whole-body protein deposition (Pd) is a main determinant of AA requirements of gestating gilts; however, data on the dynamics of Pd is limited. The main objective of this study was to measure whole-body Pd (pregnancy-associated and maternal) during gestation in gilts at 2 feeding levels. Changes in BW and backfat (BF) throughout gestation and subsequent lactation performance were also evaluated...

This study a) compared the effects of buprenorphine versus methadone maintenance on benzodiazepine and alcohol use and b) evaluated the prognostic significance of gender and psychopathology and their interaction with maintenance treatment. Eighty male and 36 female patients were randomly assigned to daily sublingual buprenorphine (4 or 12 mg) or oral methadone (20 or 65 mg). Maintenance medicat...

On the 15th August, 1930, S., a well developed Hindu girl of 16, was brought to my dispensary from a near by village, for retention of urine and severe pain of a bursting type in the lower abdomen. The history obtained was of a very vague type, and all that could be gathered from her parents, was that the trouble commenced some 20 days previously when the patient had sudden pain in the abdomen ...

AIMS Methadone maintenance treatment has been made available in China in response to the rapid spread of human immunodeficiency virus (HIV), but high rates of dropout and relapse are problematic. The aim of this study was to apply and test if a contingency management (or motivational incentives) intervention can improve treatment retention and reduce drug use. DESIGN Random assignment to usua...

Postoperative salt and water retention has been recognized for most of this century. Does it matter? Can or should it be avoided? These are still questions about which debate continues. Pringle, in 1905, observed reduced urine volumes and weight gain in postoperative patients [31]. Wilkinson studied 27 patients perioperatively and observed a decrease in urinary concentrations of sodium and chlo...

Herd health and production related problems were monitored on a high yield farm with 385 Holstein-Friesian cows near Ljubljana, Slovenia in 1993. At the end of August an outbreak of acute aseptic inflammation of the corium of the hoof (N=33) and retention of urine in vagina (N=37) was detected and treated in cows at pasture. The incidence of the disease in the summer months (pasture) was statis...

The aim of this study was to analyse the outcome of trial off catheter for patients who were admitted to the Department of Urology, Singapore General Hospital (SGH) for acute retention of urine (ARU) due to benign prostatic hypertrophy (BPH). From 1 June to 15 October 1997, 150 patients were admitted for ARU. Seventy-one patients were excluded from our study due to our exclusion criteria such a...

An internally standardized method for the determination of 3-methylhistidine in human urine is presented. This methylated amino acid and the chemically analogous internal standard 3-ethylhistidine were isolated from human urine specimens using small columns of cation-exchange resin. Quantification was accomplished by high-performance liquid chromatography using post-column derivatization with o...

BACKGROUND Hepatitis C virus (HCV) infection rates in drug users vary among different regions of China. Drug users who are unaware of their HCV serostatus tend to engage in more risky behaviors. OBJECTIVES This prospective study aimed to assess risk factors of HCV infection in drug users among 11 methadone maintenance treatment (MMT) clinics in Xi'an, China. PATIENTS AND METHODS Baseline ch...
