Background: Urany1 acetate (UA) mostly a kidney poison or chemical toxic and not nearly so much radiological also is not accumulative toxic, so it is not concentrated in the food chain nor would it cause pathological condition due to increase levels from expomers. Therefore, the study aimed to detect the target organ as most of the lethal dose (LD50) male rats died within 24 hours.
Methods: Study was done on (120) male rats of 2 months old, at varying dosage level of uranyl acetate ranging from LD 50 of 2.5 and 1.5gm/kg and varying dosage level, by oral intubation. There were (40) rats for LD 50 were given single oral dose from 2.5 to 1.5 gm /kg every day. Eighty rats for the main study, (20) rats each group as intermediate, low and high dose. After LD 50, the trail was done on groups of rats, starting as high dose as 150 mg / kg day by day then followed by intermediate dose 100 mg / kg and low dose level 75 mg / kg b.w every other day respectively with control untreated group. Duration of the study (55 day) on all rats were killed and followed by histopathological examination.
Results: The histopathological changes ranged from sever necrosis of the proximal convoluted tubules result in renal failure and that was mainly at the LD 50 and maximum level dose, rats either died after few hours or live for few days. Showing arched back and killed in poor condition, while rats treated with intermediate and low dose level showed less sever changes, mostly as dilated cortical tubules and / or cortical tubular basophilia, , only with occasional cortical tubular necrosis .
Conclusion: The Present study showed that the kidney, proximal convoluted tubules, the target for toxicological pathology of heavy metal and the main cause of death was renal failure in sever morbid cases.
Background; Polycystic disease of the• ovary is complex of symptoms with virious clinical, hormonal and biochemical abnormalities.

Aim; to test the ability of pioglitazone in correcting biochemical and hormonal changes among unmarried women with PCO.
Design; Prospective
Methods: 23 women with PCO in whom previous treatment with metformin has failed were recruited to participate in the study. All the women were single with chronic unovulation and
menstrual abnormalities and hirsutism. They were put on pioglitazone 30 mg daily for 6 months. FSH, LH, LH/ FSH, fasting insulin level, free testosterone, estradiol, and serum sex binding

A novel, safe and efficient method was developed to encapsulate a blend of essential oils (EOs) into biodegradable nanoparticles (NPs). The biodegradable and biocompatible nanoparticles were made from chitosan (CH) and lecithin (LE) . The quality of the essential oils was verified using gas chromatography/mass spectrometry (GC/MS). The synthesis of nanoparticles included emulsification, followed by sonication, homogenization, and extrusion. Transmission electron microscopy (TEM) indicated that the nanoparticles were spherical in shape with sizes ranging from 25 to 70 nm, while dynamic light scattering (DLS) showed high negative zeta potentials. The stability of the final formula was evaluated in gastric and intes

Objective: Assess oral health status in relation to salivary antimicrobial peptides in pregnant women.
Subjects and Method: This cross sectional study was carried out in different primary health care centers in Rusafa sectors/ Baghdad city. The total sample included was 80 women (their age range from 21-30). The study group consisted of 40 pregnant women: half of them were in the first trimester and others were in third trimester, while the control group included 40 non-pregnant married fem
... Show MoreBackground: Good Nutrition is essential for oral and dental health in children. Good eating habits and food preferences are established early in childhood. Oral health problems can effect dietary quality and nutrient intake in another side increase the risk of several systemic diseases., The aim of the present study was to investigate the relation or the effect the of nutritional status in children at age of 5 to16 on the oral health status and dental caries . Materials and Methods: the total sample composed of 153 patients attending the Pedodontic and Preventive Department/College of Dentistry/University of Baghdad, the assessment of nutritional status was performed by using Body Mass Index specific for age and gender according to Chronic

The basic idea of aphaeresis is efficient removal of a circulating cellular blood component, either cells (Cytopheresis) or plasma solute (plasmapheresis, plasma exchange).Thus, the treatment goal of aphaeresis is to remove the circulating cell or substance directly responsible for the disease process. Acceleration and development of aphaeresis applications had taken place with the arrival of automated cell separators in 1970s that ensure selectively removal of one or more of blood components from the blood and return the remainder to the individual. Plasmapheresis is separation of plasma from blood cells which are returned to the body.
... Show MoreIn this study, aromatic polyamide reverse osmosis membranes were used to remove zinc ions from electroplating wastewater. Influence of different operating conditions such as time, zinc concentration and pressure on reverse osmosis process efficiency was studied. The experimental results showed, concentration of zinc in permeate increase with increases of time from 0 to 70 min, and flux of water through membrane decline with time. While, the concentrations of zinc in permeate increase with the increase in feed zinc concentration (10–300 mg/l), flux decrease with the increment of feed concentration. The raise of pressure from 1 to 4 bar, the zinc concentration decreases and the flux increase. The highest recovery percentage was fou

In this study, the significant factors that affecting the adoption of cloud computing have been examined using a frequency analysis that have been explored by the previous studies. The results showed that the most effected factors were relative advantage which followed by security and privacy, complexity, innovativeness, and external support. In this study the model of technology organization-environment was used to examine the significant factors that affecting the adoption of cloud computing.
