we report a case of multiple myeloma that presented with anorexia, fatigue, high erythrocyte sedimentation rate, bone marrow plasmacytosis of more than 30%, polyuria,and low urine specific gravity. this unusual presentation was diagnosed as nephrogenic diabetes insipidus secondary to a proximal tubular dysfunction. the tubular functional disturbance appeared to be related to the presence of lam...

the aim of the study was to describe the urinary electrophoretic pattern of dogs with heartworm disease.urine samples from 15 heartworm-infected and 15 healthy dogs were taken. urinary specific gravity, urinaryprotein concentration and the urine protein/creatinine (u p/c) ratio were determined. urine proteins werefractionated using sds-page. results showed statistically significant differences ...

OBJECTIVE: To investigate the reliability and validity of refractometry, hydrometry, and reagent strips in assessing urine specific gravity in collegiate wrestlers. DESIGN AND SETTING: We assessed the reliability of refractometry, hydrometry, and reagent strips between 2 trials and among 4 testers. The validity of hydrometry and reagent strips was assessed by comparison with refractometry, the ...

The performance of a prototype instrument, “CLINILAB Automated Urine Analyzer,” for automation and mechanization of urinalysis, was studied. Results of the chemical tests for which the instrument is used-pH, glucose, protein, ketone, bilirubin, and occult blood-were compared to those obtained on the same urine specimens by using “‘Bili-Labstix’ Reagent Strips.” Results for specific gravity obta...

BACKGROUND Microalbuminuria is known to be a harbinger of serious complications in type 2 diabetes mellitus. Since medical intervention at the onset of microalbuminuria can be critical in reducing these adverse outcomes, it is widely agreed that type 2 diabetic patients should be screened for microalbuminuria. The purpose of the present study is to evaluate Micral test strips in conjunction wit...

The effects of density and food on remating were investigated using Drosophila melanogaster. The frequency of remating was unaffected by density for some combinations of fly strains but was reduced at low relative densities for other combinations. Until females had used most of their stored sperm, remating was less likely when food was absent or contact with food was prevented. Food availabilit...
