In the present study, the effects of brake pad particles of lung and liver histological sections were evaluated for (60) adult male mice. The animals were divided into three groups ( A,B,C) according to the periods of exposure (4, 8, and 12) weeks respectively exposed to brake pad particles in addition to the control groups (F) exposed to fresh air only. A special inhalation chamber designed locally has been used to expose the animals. The exposure to brake pad particles was (2.228) µg/m³ for 30 min/day, 5 days/week for (4,8and12) weeks respectively.

The examination in group (A) of the histological sections of the lung showed the thickness of interalveolar septa.  Also, a congestion of alveolar capillary was marked indicat

            The present study aimed to investigate the histological changes of heart, lung, liver and kidney which caused by different concentrations (10, 20 and 40 mg/kg) of Ivabradine. Results of the study revealed some histological changes represented by aggregation of the lymphocytes around respiratory bronchioles of the lung. In the liver, the drug caused hepatocyte necrosis and infiltration of the lymphocytes. In Kidney, there are no histopathological modifications in the tissue after the animals treated with 10 mg\kg of Ivabradine. When the animals treated with Ivabradine drug at 20mg/kg of bw, dose showed vascular congestion between myocardial fibers of heart. Emphysematous c

Air pollution is a major environmental problem, due to the increasing number of vehicles in Baghdad city streets and their direct impact on the process of air pollution resulting from an exhaust and non-exhaust pollutants (brake, clutch, tire wear, road surface wear and corrosion of vehicle components).

     The aim of this study is to detect the chemical and physical properties of brake pad particles as well as the concentrations of heavy metals found in these pad particles. This study included, a collection of eleven (11) samples of brake pads belong to different types of cars, most of these cars were used commonly in Baghdad city streets. The size of break  pads particles was examined under Scanning El

The present study was conducted using 15 adult male Swiss albino mice (weighing 35-45g). They were equally divided into three experimental groups. The first group was only given water as control during experimentation period (28days). Both of the second and third groups of mice were daily given a subcutaneous injection of cadmium as cadmium chloride (CdCl2) at a dose of 2mg and 4 mg Cd/Kg body weight respectively. The examination of the histological sections of the second experimental group of mice showed abundant histological changes in the hepatocytes such as increased size, presence of spaces and dense appearance of the cytoplasm, whereas these changes were more abundant in the hepatocytes of the third experimental group of mice in co

The present study was conducted using 16 adult male Swiss albino mice (weighing 40-50g). They were equally divided into four experimental groups. The first group was only given tap water as control during experimentation period (40 days). Group II, group III and group IV of mice were daily given a subcutaneous injection of cobalt as cobalt chloride (CoCl2) at a dose of 20mg, 40mg, and 60mg /Kg body weight respectively. The examination of the histological sections of the second experimental group of mice (low dose group) showed no particular changes in the columnar epithelial cells of the duodenum of mice. The examination of the histological sections of the third experimental group of mice (moderate dose group) showed abundant degenerativ

   The present study aimed to investigate the morphological description and histological structure of kidney in adult albino mice (Mus musculus), The anatomical study revealed that the kidney in albino mice is represented by bean-like shape, smooth with red to brown color, It is situated within the anterior half of abdominal cavity under the diaphragm on both sides of vertebral column. The kidney is covered by capsule of loose connective tissue with mean thickness of (9.6±0.5) micrometer. Histological examination revealed that albino mice kidney tissue differentiated into cortex and medulla, the cortex contains glomeruli with mean diameter of (50.5±1.9) micrometer densely distributed at the peripheral area of the cortex ,

Background: A number of investigators have carried out experimental infections of hydatidosis, using albino mice as an experimental animal model, but there was disagreement on the effect of strain, sex and age of this model.
Materials and Methods: Two hundred and forty mice (120 males and 120 females) were injected intraperitoneally with a single dose of 2000 protoscolices (PSCs) /mouse at four ages (3-4, 7-8, 10 and 20 weeks). Each age group consisted of 60 mice (30 males and 30 females); in which 15 animals of each sex were the treated group, while the other 15 animals were a control group (injected with normal saline). Five animals from each age and sex were sacrificed at one, two and four month po sti

The chamomile is one of the most important medicinal plants recommended for treatment of asthma and some respiratory system diseases. This research was designed to research the effects of aqueous extract of chamomillarecutita on histological structure of Diaphragm of albino mice. The study included 40 male albino mice Musmusculus, their age ranged from (5-7) weeks.The mices were divided randomly to 5 groups and oral administered with 1 ml every day for 10 days:- First Group G1: consider as control group and treated with normal saline,Second Group G2: was treated with aqueous extract of chamomile with concentration of 3 gm /100 ml D.W, Third Group G3: was treated with aqueous extract of chamomile with concentration of 5 gm /100 ml D.W.Fourth
