The present study represent the histological and histochemical structure of the esophagus of laughing dove Streptopelia senegalensis, one of the wild birds, which feed on the seeds( grainvorous).The result showed that the esophagus long tubular quit wide and highly distensible organ situated at the right side of the nick , lie between pharynx and stomach it was divided into cervical and thoracic part , the cervical part longer than the thoracic part, and the crop was merely enlargement fusiform in shape which located at the entrance of the thorax. Esophagus parts showed that composed of four layer ;the mucosa, sub mucosa, muscular and adventitia or serosa, the mucosal layer was arranged in folds which was longer in the c

Back ground: The study was conducted on fifty patients (27 males and 20 females) with chronic renal failure (CRF) undergoing maintenance hemodialysis (HD), at
artificial Kidney unit, Al- Hakeem Hospital / Najaf, during the perioed from April to June 2008.
Patients & methods: Plasma osmolarity ( Posm), plasma creatinine (P cr ) plasma urea (P urea)>plasma sodium (P Na)and plasma potassium ( P k )were measured for
all patients before and after dialysis.
Results: The paired t -test was used to compare the pre-dialysis values with the post dialysis values and simple linear correlation to study the relation between (P
Na), and ( Posm), p values less than 0.05 considered not significant. The result of&

Racism changes its meaning, shape, purpose or function according to various factors such as time, place, motives, and backgrounds; among others. It seems, however, to have deep roots back in the history of mankind. Such a concept stems from a perceived difference with the other. It is fed by the feeling of being hierarchically superior in opposition to another party that is depicted as inferior. Since ancient times, racism is disguised in different forms and manifests itself on various levels. It is a truism that this ideology can be best presented via language.

Due to its negative implication, racism lends itself to a critical kind of research.  As such, this paper is a critical pragmatic investigation for this phenomenon a

The present study deals with the assessment of water Quality Index to theAl-
Khadhimiya Groundwater city, by collection groundwater from 13wells during four
seasons, subjecting the samples to a comprehensive physicochemical analysis. The
13 parameters have been considered: pH, total hardness, calcium, magnesium,
turbidity, nitrate, electrical conductivity, total dissolved solid, Sulfate, Chloride,
zinc, manganic, and iron, that are used for calculating the WQI. From the result
shown, the most groundwater quality lies in Unfit for human drinking purpose. The
wells (1 and 11) and wells (3 and 10) were a bad water quality for drinking purpose
since they lie in poor and in very poor respectively according to the WQI.

Background: Pulmonary tuberculosis is a chronic infectious disease which affects nutritional status of the patients. The presence of poor nutritional status in pulmonary tuberculosis patients has been one of the most important determining factor in recommending adjuvant nutrient therapy to prevent oxidative stress and further complication.
Objective: This study was designed to assess the nutritional status and body mass index of pulmonary tuberculosis patients.
Patients and methods: During the period 1st of June 2010 to 30th of May 2011, a prospective study was done on 60 patients with active pulmonary tuberculosis and 60 controls.
Levels of total protein (TP), albumin (ALB.), triglyceride (TG), total cholesterol (TC), high dens

Perchloroethylene (PERC) is commonly used as a dry-cleaning solvent, it is attributed to many deleterious effects in the biological system. The study aimed to investigate the harmful effect associated with PERC exposure among dry-cleaning workers. The study was carried out on 58 adults in two groups. PERC-exposed group; include thirty-two male dry-cleaning workers using PERC as a dry-cleaning solvent and twenty-six healthy non-exposed subjects. History of PERC exposure, use of personal protection equipment (PPE), safety measurement of the exposed group was recorded. Blood sample was taken from each participant for measurement of hematological markers, liver and kidney function tests. The results showed that 28.1% of the workers were usin

Autoimmune hepatitis is an inflammatory disease and its incidence has been increasing. The features of hepatitis are the release of inflammatory cytokines, the elevation of AST and ALT, and hepatocyte apoptosis and necrosis. Concanavalin A considered as essential model represents the acute immune-mediated liver damage in rodents. Thymoquinone is well known herbal compound that exert hepatoprotective, anti-inflammatory, and antioxidant activity. In this study, we focus on the immunoregulatory and liver protective effect of thymoquinone in a mouse model of concanavalin A-induced liver injury.

Twenty-four male mice were randomly divided into four groups each containing six animals: Negative control group, concanavalin A model group,

    The goal of this research is to use optical emission spectroscopy to investigate the parameters of exploding silver wire plasma. The silver discharge plasma's emission spectra were recorded and studied. For silver wire of diameter 0.4 mm and different currents 75,100, and 125A in deionized water, the plasma electron temperature ( ) was calculated by Boltzmann plot and container plasma medium temperature by thermal camera, and the electron density ( ) was computed by Stark broadening using the hydrogen (H line) at 656.279 nm With increasing current from 75 to 125 A, the electron density (n_e) increased from 3.160×  to 8.762×   , while electron temperatures increased from 0.571 to 1.334 eV under the same conditions. 

The current study included a detail morphological study of all parts of the two species of the genus Tropaeolum L. (Tropaeolumceae) cultivated in different gardens, the roots, stems, leaves, flowers and fruit were studied in detail, also the pollen grains were studied, and there are photographs for all that parts were putted. A specimens of that taxa were studied in some Iraqi herbaria. The study found that there are many characters were used in differentiation of two species under study.

The emergent bacterial resistance to antibiotics, most especially Carbapenems, has become a common phenomenon. The aim of the recent study was the observation and evaluation of the antibacterial susceptibility of Klebsiella pneumoniae in clinical specimens to different Carbapenems. One hundred isolates of K. pneumoniae isolated from different clinical sites, such as leg, caesarean section (CS), head, buttock, breast, thigh, and arm were tested. Using disc diffusion method, the isolates were tested for susceptibility to different antibiotics including Tobramycin, Ciprofloxacin, Aztreonam, Colistin sulphate, Ceftriaxone, Cefepime, Cefoxitin, Ceftazidime, Ertapenem, Meropenem, and Imipenem. The results were interpreted acc
