[ 1 ] - Is Tc99m-MIBI scintigraphy a predictor of response to pre-operative neoadjuvant chemotherapy in Osteosarcoma?

Objectives: Multidrug resistance (MDR), which may be due to the over expression of P-glycoprotein (Pgp) and/or MRP, is a major problem in neoadjuvant chemotherapy of osteosarcoma. The aim of this study was to investigate the role of Tc-99m MIBI scan for predicting the response to pre-operative chemotherapy. Materials and Methods: Twenty-five patients (12 males and 13 females, aged between 8 and...

[ 2 ] - Thymoquinone restores liver fibrosis and improves oxidative stress status in a lipopolysaccharide-induced inflammation model in rats

Objective: Liver fibrosis is the primary sign of chronic liver injury induced by various causes. Thymoquinone (TQ) is the major ingredient of Nigella sativa with several beneficial effects on the body. In the present study, we aimed to investigate the effect of TQ on liver fibrosis in a lipopolysaccharide (LPS)-induced inflammation in male rats. Materials and methods: Fifty male Wistar rats wer...

[ 3 ] - Effects of Erythropoietin on Electrocardiogram Changes in Carbon Monoxide Poisoning: an Experimental Study in Rats

The aim of this study was to define the electrocardiogram (ECG) changes following the moderate to severe CO intoxication in rats, and also evaluating the effect of erythropoietin (EPO) on observed cardiac disturbances. The growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. Wistar rats were exposed...

[ 4 ] - Childhood Facial Osteosracoma: a Case Report

Osteosarcoma (OS) is the eighth common cancer of childhood and its incidence is 4 cases in one million in children younger than 14. Facial OS incidence is estimated between 8 and 10% of OS cases. The main etiology of OS is unknown, but various predisposing factors are proposed such as radiation, radiotherapy, some benign bone diseases like Paget’s disease or fibrous dysplasia. There is a 5-year...

[ 6 ] - Protective effect of Rheum turkestanicum root against mercuric chloride-induced hepatorenal toxicity in rats

Objective: The present study was designed to investigate the protective effects of hydroalcoholic extract of Rheum turkestanicum against HgCl2 hepatorenal toxicity in rats. Materials and Methods: Animals were randomly divided into five groups (n= 6 in each group) and received HgCl2 and plant’s extract, intraperitoneally. Group1 received saline (1 mL/kg/day), group 2 received extract (200 mg/kg/...
