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.

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.

Evaluation of boldenone as a growth promoter in broilers: safety and meat quality aspects.

The object of this study was to evaluate the safety and meat quality criteria in broilers following intramuscular injection of boldenone. Twenty-four broiler chicks, divided into two groups, were used in the present study. Boldenone was injected intramuscularly at a single-dose level of 5 mg/kg body weight into 12 broiler chicks at 2 weeks old; the other 12 chicks were injected with sesame oil and kept as controls.

Effect of long-term administration of sildenafil on lipid profile and organ functions in hyperlipidemic rats.

The aim of the present study was to elucidate the possible biochemical alterations in lipid metabolic profile and organ function profiles that may result from continuous treatment with the drug, sildenafil in normal and hyperlipidemic rats. Blood samples were taken for biochemical analysis on days 30, 45 and 60 of the experiment. Sildenafil (5.

Neurally released ATP mediates endothelium-dependent hyperpolarization in the circular smooth muscle cells of chicken anterior mesenteric artery.

The object of the present study was to clarify the neurotransmitter(s) controlling membrane responses to electrical field stimulation (EFS) in the circular smooth muscle cells of first-order branches of chicken anterior mesenteric artery.EFS (five pulses at 20 Hz, 1 ms) evoked a hyperpolarization of amplitude--21.6+/-1.

An electrophysiological study of excitatory purinergic neuromuscular transmission in longitudinal smooth muscle of chicken anterior mesenteric artery.

Successful abrogation by thymoquinone against induction of diabetes mellitus with streptozotocin via nitric oxide inhibitory mechanism.

Nitric oxide (NO) is involved in the destruction of beta-cells during the development of type I diabetes mellitus (DM). We demonstrated the possibility of rescuing beta-cells by intervention with thymoquinone (TQ) using streptozotocin (STZ) rat diabetic model. The hyperglycemic and hypoinsulinemic responses to STZ were significantly abrogated in rats cotreated with TQ, and this abrogating effect has persisted for 1 month after stopping of TQ treatment.

Nitrergic prejunctional inhibition of purinergic neuromuscular transmission in the hamster proximal colon.

Neurogenic ATP and nitric oxide (NO) may play important roles in the physiological control of gastrointestinal motility. However, the interplay between purinergic and nitrergic neurons in mediating the inhibitory neurotransmission remains uncertain. This study investigated whether neurogenic NO modulates the purinergic transmission to circular smooth muscles of the hamster proximal colon.

An endothelium-derived factor modulates purinergic neurotransmission to mesenteric arterial smooth muscle of hamster.

The interaction between the endothelium and purinergic perivascular nerves was investigated by measuring the changes in amplitude of excitatory junction potential (EJP) of smooth muscle cells in hamster mesenteric arteries (100-350 microm). Uridin-5'-triphosphate (UTP) (100 microM) applied to endothelium-intact preparations evoked a hyperpolarization of 17.0 +/- 0.
