Evaluation of Antioxidant Activity of Acoholic Extracts from Pleurotus ostreatus (P2) In Vivo

In this study found treatment mice exposed to CCl4 with the alcoholic extract of Pleurotus ostreatus (P2) at (25) mg/ml appeared to exert a beneficial effect since the activities of catalase, was significantly (p<0.05) higher in liver treatment with alcoholic extract of P. ostreatus (P2) (37.290+2.638) μmol/mg than in aqueous extract for the same fungus (36.557+2.231) μmol/mg. Super oxide dismutase (SOD) was significantly (p<0.05) higher in liver treatment with alcoholic extract of P. ostreatus (P2) at (25) mg/ml (17.863+0.454)U/mg than in aqueous extract (17.863+0.454) U/mg for the same fungus and same concentration. Glutathione peroxidase (Gpx) was significantly (p<0.05) higher in liver treatment with alcoholic extract of P. ostreatus(P2) at (25) mg/ml (29.260+1.666)μmol/mg than in aqueous extract (24.660+1.130)μmol/mg for the same fungus and same concentration. Alcoholic extract of P .ostreatus (P2) at (25) mg/ml induce a non-apoptotic, apoptosis was (0.0657+0.0047%) ,in aqueous extract was (0.0770+0.0060%). Histopathological study appeared liver cells exposed to CCl4, CCl4 made severe degeneration and necrotic change in liver parenchyma by evidence of apoptosis in some hepatocytes , in sinusoids showed slight congestion with blood vessel and thrombus formation. Liver cells of mouse exposed to CCl4 and treated with alcoholic mushroom extract and appeared the liver cells returned like control. the tissue treatment by aqueous extract of P.ostreatus (P2) at (25) mg/ml appeared mononuclear cells aggregation.

The auditor's qualifications and their role in the quality of professional performance

 

Abstract

The aim of the research is to clarify the requirements of the qualification of the external auditor in Iraq and the extent of their impact on the quality of the professional performance of the audit process. The research was based on analyzing the results of the questionnaire prepared for the impact of qualifications on the quality of professional performance. The researcher has reached a number of conclusions, the most important of which is that a highly qualified and unethical auditor has a greater negative impact on the quality of professional performance than those with low qualifications. The most important recommendations of the research were the need to pay

Spectrophotometric Determination of Epinephrine in Pharmaceutical Preparations Using Praseodymium as Mediating Metals

A simple, accurate and sensitive spectrophotometric method for the determinaion of epinephrine is described . The method is based on the coordination of Pr (III) with epinephrine at pH 6. Absorbance of the resulting orange yellow complex is measured at 482 nm . A graph of absorbance versus concentrations shows that beer 's low is obeyed over the concentration range (1-50)mg.ml-1 of epinephrine with molar absorpitivity of ( 2.180x103 L.mol-1.cm-1 ), a sandell sensitivity of (0.084 mg.cm-2 ), a relative error of (-2.83%) , a corrolation coffecient (r= 0.9989) and recovery % ( 97.03 ± 0.75 ) depending on the concentration.This method is applied to analyse EP in several commercially available pharmaceutical preparations

Using the plastic wastes in fabrication of composite materials for different applications

This study suggests using the recycled plastic waste to prepare the polymer matrix composite (PMCs) to use in different applications. Composite materials were prepared by mixing the polyester resin (UP) with plastic waste, two types of plastic waste were used in this work included polyethylene-terephthalate (PET) and Polyvinyl chloride (PVC) with varies weight fractions (0, 5, 10, 15, 20 and 25 %) added as a filler in flakes form. Charpy impact test was performed on the prepared samples to calculate the values of impact strength (I.S). Flexural and hardness tests were carried out to calculate the values of flexural strength and hardness. Acoustic insulation and optical microscope tests were carried out. In general, it is found that UP/PV

The Behavior of Bond Strength between Rebar and Concrete in Rubberized Concrete : -

Through an experimental program of eighteen specimens presented in this paper, the bond strength between reinforcing bar and rubberized concrete was produced by adding waste tire rubber instead of natural aggregate. The fine and coarse aggregate was replaced in 0%, 25%, and 50% with the small pieces of a waste tire. Natural aggregate replacement ratio, rebar size, embedded rebar length, the rebar yield stress of rebar, cover, and concrete compressive strength were studied in this investigation. Ultimate bond stress, bond stress-slip response, and failure modes were presented. The experimental results reported that a reduction of 19% in bond strength was noticed in 50% replaced rubberized concrete compared with convention

Indirect Spectrophotometric Determination of Oxymetazoline Hydrochloride in Pharmaceutical Formulation Using Fluorophotometric Method

This research involves an indirect Fluorophotometric method for the determination of microgram amount of oxymetazoline hydrochloride in the concentration range 0.1-5.0 g/ml. The method is based on the oxidation of the drug by cerium sulphate solution which is acidic medium where Ce IV is reduced to Ce III which can be excited at 259 nm to give an emitted light at 377 nm which  is directly proportional to the concentration of Ce III which is equivalent to Ce IV that is needed to oxidize the studied drug. The average recovery of the method is 100.19% and relative standard deviation (RSD) < 0.37% . The method have been successfully applied to the determination of the studied drug in its pure and pharmaceutical preparations and it wa

Preparation of the Epoxy / Chicken Eggshell Composites to use in Surfaces Coating

    In this  work , impact strength and the water absorption  ratio of powders of white and brown local chicken eggshell reinforced epoxy with different volume fractions ( 1 , 2 , 3 , 4 and  5 % ) were studied .       The experimental results show that composite filled by ( 1 % Vol . )of white eggshell powder exhibited  maximum  impact  strength and high resistance to tape water , so we choose this volume fraction to use the epoxy composite in coating . Optical microscopic observations are taken to develop a better  understanding of the phenomena taking place in the material system at microscopic level .

Prevalence of substance use disorders among prisoners in Al- Diwania governorate, Iraq

Background: Substance use disorders (SUDs) are among the common psychiatric disorders and constitute a major public health concern. Iraqi’s were exposed to widespread violence and wars in the last decades. High prevalence of alcohol and substance use was reported recently in Baghdad. Research literature documented the association of SUDs with exposure to trauma events e.g. wars, terrorist attacks and natural disaster. Published articles on SUDs among prisoners in Iraq are scarce. Therefore, this work was carried out to report on SUDs among prisoners in Al-Diwania governorate and its relation to antisocial activity.
Methods: A total of 1200 prisoners in Al-Diwania civilian prison were included in the stu

Correlation between Computerized Tomography Densimetry and Histomorphometry in Assessment of Bone Healing

Background: Assessment of fracture healing is a common problem in orthopedic practice and research. Computerized Tomography (CT) is a reliable tool for quantification of the fracture repair process in experimental animals. Histomorphometric evaluation provides a clear quantitative evidence of the bone healing process. The evaluation by micro-architectures in healing bone showed variable correlation between CT and histomorphometry.
Material and methods: open ulnar osteotomy induced in twenty young male rabbits under general anesthesia without internal fixation, and divided into five groups. A group of animals were sacrificed at end of 2nd week, 3rd week, 4th week, 5th week, and 6th week. The right ulna iso

Consumer Use of E-Banking in Iraq: Security Breaches and Offered Solution

    After the software revolution in the last decades, the field of information technology had a tremendous evolution that made many organizations reach the best benefits from this evolution in technologies. The banking sector evolved their old system from ordinary system to the online system. The term E-banking appears to cover almost all bank operations such as money transactions, account management, instant reports, instant notifications. E-banking offers several advantages to clients, but this opens many challenges and motivates unauthorized parties to focus on creating methods and exploiting weaknesses to attack and steal critical information that belongs to the banking system or clients. Iraqi banks recently adopted E-banking se
