A rapid and reproducible method is described for measurement of urea in biological materials (after deproteinisation) and in serum (without deproteinisation). Urea is colorimetrically determined with diacetyl monoxime and thiosemicarbazide in the presence of sulphuric acid, phosphoric acid and ferric chloride. The sensitivity of the colorimetric reaction and stability of the colour are enhanced...

abstract background: sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood ph in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (g6pd) deficiency. the aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and ...

The aim of this study was to determine whether decreased serum sodium concentration could be associated with the disease activity in SLE. We retrospectively analyzed the data of the two independent cohorts of children and adults with SLE in two centers. Hyponatremia was associated with serum chloride (p = 0.004), albumin (p = 0.002) and SLE disease activity index (SLEDAI) (p = 0.026) in childre...

the effect of genotype and sex of nigerian indigenous chickens (dwarf, fulani ecotypes, neck, frizzle and normal feathered) on blood serum electrolytes and biochemical parameters were investigated using 40 chickens. the collected data were subjected to analysis via a 2 way anova. the results revealed serum levels of sodium, potassium, chloride, uric acid, glucose, total protein, creatinin, albu...

background : the rapid  development of  the mining and industry activities increased and many toxic metals  in the environment of the earth's crust has been dissipated  and t  has taken  risks to human exposure, inhalation. today evidence of many  diseases associated with environmental  factors  harmful to repellent bio systems is increasing gradually , the majority of these factors  were man-m...

The aging kidney is a marked by a number of structural and functional changes, including an increased susceptibility to acute kidney injury (AKI). Previous studies from our laboratory have shown that aging male Fischer 344 rats (24 month) are more susceptible to apoptosis-mediated injury than young counterparts. In the current studies, we examined the initial injury and early recovery phases of...

The losses of sodium, potassium, chloride, nitrogen, and water following the administration of diuretin to rabbits over 5 to 9 day periods together with the changes in serum concentrations of sodium, chloride, N. P. N., and total protein occurring simultaneously with these losses are described. The circumstances responsible for the presence of azotemia in the animals were investigated in partic...

cobalt is an essential co-factor in red blood cell production and function and its deficiency may produce clinical signs in sheep. thus, present study was designed to evaluate the effect of cobalt nano-particles on serum biochemical factors and histopathological changes in liver and kidnies of lambs. study was carried out in 3 groups of lambs (4 lambs per group). one group of lambs was kept as ...
