histidine at the doses 30 and 60ml /kg had no effect when injected at 7 :ooh, or at 19:00h. histidine at the doses of 120, 240 and 480 mg / kg decreased defecation at the first 8 and 24 hours post injection, respectively, when injected at 07:00h. the amino acid at the doses of 120, 240 and 480 mg / kg decreased the number of fecal pellets at 2, 8 and 24 h post injection, respectively, when inje...

Introduction:The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar ima...

Combined acute inhibition of the synthesis of nitric oxide with L-nitroarginine methyl ester (L-NAME) and of prostacycline synthesis with indomethacin predisposes rats to severe renal injury from radiographic contrast media. The reliability of this pharmacological manipulation in the study of radiographic contrast medium induced nephropathy (RCMN) was investigated. Adult male Sprague-Dawley rat...

this study was carried out to examine the effect of post hatch fasting (phf) period with and without subcutaneous injection of 0.6 ml ca-gluconate (ca-g) on productive performance and breast muscle development in broiler chicks up to day 28 of age. weight gain (wg) and feed intake (fi) were significantly reduced and fcr was increased as phf lasted for 36 h. injection of ca-g did not improve wg ...

We studied the effects of black fat-tailed scorpion (Androctonus bicolor) venom on the activities of liver enzymes including alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH) and creatine kinase (CK) in the sera of rats. The animals were subcutaneously injected with a single dose of crude A...
