Objective: The concentration-dependent nephroprotective effects of orally-administered aqueous green tea extract (AGTE) were studied. Materials and Methods: Forty rats of both sexes (weighing ٢٠٠-٢٥٠g) with various concentrations {٠.٦٢٥%, ١.٢٥% and ٢.٥% of aqueous green tea extract (AGTE)} as their main source of drinking fluid ٧ days before and ٥ days after administration of methotrexate (MTX). The parameters of oxidative stress, malondialdehyde (MDA) and reduced glutathione (GSH) were daily measured in kidney homogenate in addition to histopathological examinations after killing. Results: Analysis of data revealed significant amelioration of oxidative stress in groups of animals treated with different concentrations of AGTE compared to MTX-treated group as evidenced by lowering MDA contents and elevation of GSH levels in kidney tissue homogenate but the levels still significantly different compared to controls. Furthermore, increasing concentrations of AGTE produce no concentration-dependent improvement of the damage induced by MTX in kidney tissue, as observed in kidney rats sections in concentrations ٠.٦٢٥% and ٢.٥% AGTE, while improvement in renal morphological changes was observed in group of animals treated with ١.٢٥% AGTE + MTX. Conclusion: The concentration-dependent protective effects of AGTE against MTXinduce kidney damage were not evidenced, where higher concentration of AGTE (٢.٥%) used in this study resulted in deterioration in the renal functions and morphology, which may be due to its pro-oxidant effect; while renal protective effects was evidenced in a concentration of ١.٢٥% AGTE, an effect that could be related to its antioxidant properties at this concentration.
Background: The adverse effects of drugs can damage various organs, especially the liver, leading to a hepatic injury known as hepatotoxicity. Drug-induced liver injury (DILI) is challenging nowadays because of the large number of different drugs used, one of the offending medications that cause DILI is carbamazepine (CBZ), since the liver has an array of functions including detoxification, it will deal with several damages caused by exposure to the drugs. Objective: investigate the effect of (CBZ) 20mg/kg/day on female mice liver after 14 and 30 days of treatment on morphological and histopathological levels. Materials and Methods: 20mg/kg/day of CBZ was administered orally for (14) days to (10) female mice, another (10) mice were taking t

Our attempt is using a biomaterial system that is easily obtained and applicable and has the ability to provoke osteoinductive growth factor to enhance bone formation at the site of application. One of these natural polymers is hyaluronic acid. Material and methods: Sixty machined surface implants from commercially pure titanium rod inserted in thirty NewZealand rabbits. Two implants placed in both tibia of each rabbit. The animals scarified at 1, 2 and 4 weeks after implantation (10 rabbits for each interval). For all of animals the right tibia’s implant was control (uncoated) and the left one was experimental (coated with 0.1ml Hyaluro

A test rig was designed and constructed for this purpose was installed at the water tests laboratory of the Department of Water Resources Engineering at the University of aghdad. The investigation was carried out by using two types of soil, different flow velocities throughout magnetizing device and different configuration of magnets over and under the water passage of the magnetizing device. The soils that were used in the experiments are clayey and sandy soils. Six different flow velocities throughout magnetizing device ranged between 0.29 to 1.19 cm/s and ten configurations of arranging the magnets over and under th

Show MoreAnabolic androgenic steroids (AAS) are man-made derivatives of the male sex hormone testosterone, originally designed for therapeutic uses to provide higher anabolic potency with lower androgenic effects. Increasing numbers of young athletes are using these agents illicitly to enhance physical fitness, appearance, and performance despite their numerous side effects and worldwide banning. Today, their use remains one of the main health problems in sports because of their availability and low price. The present study focuses on investigating the adverse effects of anabolic androgenic steroid abuse on sex hormones, liver and renal function tests, fasting glucose levels and lipid metabolism in Iraqi male recreational bodybuilders

This study aimed to identify three samples of this genus in Mosul city in February and April 2019. Three species of Ganoderma were collected from three various trees including Eucalyptus, Morus, and Olea (olive) in Mosul City, Northern Iraq. Their identifications and their DNA sequences were genetically identified by using PCR techniques according to detect nuclear ribosomal internal transcribed spacer (ITS) regions. Results exhibited the finding of Ganoderma resinaceum, Ganoderma applanatum, and Ganoderma sp. This study is first attempt to identify Reishi Mushroom by molecular methods in Iraq.
