New, precise, physical methods for the determination of total protein in serum or plasma and in urine are described. They are based upon the refractometric determination of total solids in these fluids before and after protein has been removed by coagulation and, in ordinary use, they require no special standardization or calibration. The urine method is applicable primarily to protein concentr...

BACKGROUND Dehydration is a health risk for miners in tropical regions of Australia. However, it is not known whether dehydration poses a health risk to miners working in temperate regions of Australia. METHODS A cross-sectional study of 88 miners from two underground mines was undertaken in south-eastern New South Wales, Australia. Participants had their height, weight, waist circumference a...

We conducted this study to identify the clinical features and risk factors for atypical acute post-streptococcal glomerulonephritis (APSGN). Thirty-five cases of atypical APSGN treated at Srinagarind Hospital during 2002-2009 were compared with 27 typical cases. The clinical symptoms, anti-streptococcal antibody titers, and laboratory data at the first hospital visit were compared between the t...

Changes in body water elicit reflex adjustments at the kidney, thus maintaining fluid volume homeostasis. These renal adjustments change the concentration and color of urine, variables that can, in turn, be used as biomarkers of hydration status. It has been suggested that vitamin supplementation alters urine color; it is unclear whether any such alteration would confound hydration assessment v...

Occupational exposure to tetrahydrofuran (THF) was studied by analysis of environmental air, blood, alveolar air, and urine from 58 workers in a video tape manufacturing plant. Head space gas chromatography (GC) with an FID detector was used for determination of THF concentration in alveolar air, urine, and blood. Environmental exposure to THF was measured by personal sampling with a carbon fel...

Herrick [1] was the first to discover sickle cell hemoglobin ( 2 2) with sickle-shaped erythrocytes. In 1910, he described the case of a young black student from the West Indies with severe anemia characterized by “peculiar elongated and sickle-shaped red blood corpuscles.” Herrick also noted a slightly increased volume of urine of low specific gravity and thus observed the most frequent featur...

AIM This study was performed to determine the accuracy of ultrasound (USG) as compared to mammography (MMG) in detecting breast cancer. METHODS This was a review of patients who had breast imaging and biopsy during an 18-month period. Details of patients who underwent breast biopsy were obtained from the department biopsy record books and imaging request forms. Details of breast imaging findi...
