Anew spectrophotometeric method for determination of ascorbic acid(A.A) in aqueous solutions depending on its ability to reduce the colors of permanganate at (530nm) and dichromate at (350 nm). The optimum conditions such as best concentration of reactant and order of addition were studied to get the highest sensitivity (ε=2355.70 and 3094.75) L.mol -1 .cm -1 with wide range of calibration curves (1-16) and (2-90) ppm good repeatability (RSD% 0.73 and 1.49), the recovery %(100.20 and 99.42), E rel % (-0.20 and 0.58) for gave, Pharmaceutically prepared tablets were measured with the new technique using Standard Addition Method given a very good recovery % (101.25 and 98.75) with a small E rel % (-1.25 and 1.25).
The erythrocyte sedimentation rate (ESR) is commonly used to assess the acute phase of the inflammatory response and to diagnose conditions associated with acute and chronic inflammation, including infections, cancers, and autoimmune diseases. Packed Cell Volume (PCV) is the height of the red cell column to the total height of the column of whole blood. This study included 100 healthy subject divided into two groups: females group (50) and males group (50). The increase in Erythrocyte Sedimentation Rate (E.S.R) was higher in women group than in men group. The result showed a negative correlation between the Packed Cell Volume (PCV) and ESR while there was a positive correlation between ESR with age and glucose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
