Hemobiomarkers of health hazard potential of metal oxide nanoparticles.

Aim: The study was designed to evaluate the possible adverse effects and consequences of metal oxide nanoparticles used on some major body organ functions and health parameters.

Materials And Methods: Thirty albino rats, allocated randomly into three groups for experimental period of 20 days post-administration were used. Different effects of metal oxide nanoparticles were targeted including, thyroid, parathyroid, kidney, calcium, phosphate, hematological parameters and indices, as well as oxidative stress markers of the red blood cells and their membranes as alpha tocopherol and GSH, by using different analytical methods.

Hepcidin-orchestrated Hemogram and Iron Homeostatic Patterns in Two Models of Subchronic Hepatic injury.

Objective: This study was designed to evaluate hematological disorders and the orchestrating roles of hepcidin and IL-6 in rat models of thioacetamide (TAA) and carbon tetrachloride (CCl4) hepatotoxicity.

Methods: Rats were intraperitoneally injected with TAA (10 mg/100 g rat weight dissolved in isosaline) or CCl4 (100 μL/100 g rat weight diluted as 1:4 in corn oil) twice weekly for eight consecutive weeks to induce subchronic liver fibrosis. Blood and tissue samples were collected and analyzed.

Hemogram and iron indices in renal anemia and the amelioration with leaf extract applied on albino rat model.

The present study was designed to look at the hematological disorders in gentamicin nephrotoxicity model, as kidney is considered as one of the hemopoietic organs. In a previous study, novel and classical kidney injury biomarkers were utilized to evaluate the nephroprotective potential of leaf extract () in the same model in albino rats. Gentamicin (100 mg/kg, subcutaneously, for 21 consecutive days) resulted in significant decreases in red blood cell (RBC) count, hemoglobin concentration (HGB), and packed cell volume (PCV) value, with minimal alterations in erythrocytic indices.

Laboratory evidence for the hematopoietic potential of Beta vulgaris leaf and stalk extract in a phenylhydrazine model of anemia.

This study was designed to provide laboratory evidence supporting the hematopoietic effect of Beta vulgaris (beet) leaf aqueous extract in phenylhydrazine-induced anemia model in albino rats. Extraction of the leaves/stalks was done by maceration in 30% hydro-ethanol for 48 h. An intraperitoneal injection of 20 mg/kg phenylhydrazine was applied for two consecutive days to develop hemolytic anemia on the 4th day after the 1st injection in 24 of 30 male albino rats.

Novel and classical renal biomarkers as evidence for the nephroprotective effect of leaf extract.

The present study is aimed at utilization of novel and classical kidney function biomarkers to evaluate the nephroprotective potential of leaf extract (CPLE) in gentamicin nephrotoxicity model in albino rats. The used classical biomarkers were urea and creatinine; while the new biomarkers were Kidney injury molecule-1 (KIM-1) and Clusterin. Forty-five male albino rats were assigned into five groups and subjected to different treatments for nine consecutive days (vehicles; gentamicin, 100 mg/kg, subcutaneously; ascorbic acid, 200 mg/kg, orally; CPLE, 150 and 300 mg/kg b wt.

The anti-nociceptive potential of tilmicosin against chemical-induced but not thermal-induced pain in mice.

The aim of the present study was to assess the analgesic activity of the macrolide antibiotic tilmicosin at dose levels of 20 and 40 mg/kg of body weight, subcutaneously, against chemical- and thermal-induced acute pains, using acetic acid-induced writhing, formalin-induced pain, hot-plate, and tail-flick models in mice. Tilmicosin showed a dose-dependent significant decrease in the number of writhes in the acetic acid-induced writhing test and significant decrease in hind paw-licking time in the late phase of the formalin test. However, it did not cause any significant changes in the reaction times to heat stimuli in the hot-plate and tail-flick models.
