Chromatographic separation of the sodium-retaining corticoid from the urine of children with nephrosis, compared with observations on normal children.

Previous studies in this laboratory have indicated that a high degree of sodium-retaining activity may be present in chloroform extracts of urine of certain patients with edema (2-6). When patients with the nephrotic syndrome are treated with ACTH or cortisone, the increased excretion of sodium in the urine is associated with a reduction in the sodium-retaining activity of the lipid extract (4,...

Relation to Sodium Balance

Patients with lipemic nephrosis, cardiac failure, and hepatic cirrhosis frequently accumulate an excess of extracellular fluid, distributed in a pattern characteristic of the underlying disease. These patients commonly have a marked impairment of sodium excretion, while glomerular filtration may be low, normal, or even increased (1-4). This impairment of sodium excretion suggested the presence ...

Assessment of Alkaline Phosphatase Activity in Hydatid Cyst Protoscolices and Liver Tissue as a Pathological Biomarker

Introduction: Hydatid cyst disease is caused by the protoscolices of Echinococcus granulosus. Alkaline phosphatase (ALP) enzyme is required for metabolism, physiology, immunology, and nutrients absorption in parasite. The aim of this study was to compare the level of ALP activity (as a pathological biomarker) in hydatid cyst protoscolices (HCP) with that of sheep liver tissue and to determine t...
