The current study was used 20 male rabbits that divided into four groups (consist of five rabbits in each group), The first group was considered as control and fed normal diet and given tap water, The second group was consisted of rabbits that fed on high cholesterol diet for six weeks, The third group was consisted of rabbits that fed on high cholesterol diet and 50mg root extract for six weeks, The forth group was consisted of rabbits that fed on high cholesterol diet and 100mg root extract for six weeks. The male rabbits that feeding on high cholesterol diet showed significant increased (P < 0.05) the levels of cholesterol, triglyceride, LDL, VLDL, MDA and HMG-CoA reductase while HDL and GSH levels were significantly decreased (P < 0.05) compared with to control group. It was concluded from this study that root extract has amply good effective role on hyperlipidemia of male rabbits.
The present study was carried out to assay the bioaccumulation of ammonia ,nitrite ,nitrate in fresh water and the concentration of heavy metals (Lead, Cupper, Cadmium, Manganes and Zinc) in water and tissues of Tilapia niloticus selected from El-marryotia canal (one of the river Nile ramification in Al-Giza city) in Egypt, samples were collected during the period of July to October 2011 to determine water safety for human consumption and the hazardous effect of these metals on the histopathology of selected tissues and organs of fish. Two samples were collected from two locations of canal, pH of water samples were measured and the concentration of ammonia, nitrate

Show MoreShatt al-Arab is the only navigational artery in Iraq, extending from the city of Qurna to its mouth in the Arabian Gulf at the city of Al-Fao within the governorate of Basrah for a length of approximately 204 km. Its width ranges from 400 m to 2000 m, and its depth ranges from 8 m to 20 m. The southern part of it, 93 km long from Umm al-Rassas Island to Ras al-Bisha, represents the international border between Iraq and Iran, where the Thalweg line represents the border between the two countries, which is the deepest point in the riverbed (according to the 1975 Algiers Agreement). The western bank (the Iraqi side) within the common border of Shatt al-Arab is subject to continuous erosion, which leads to the shifting of t

This study aimed to explain the relationship between hyperthyroidism and asthma by indicating the effect of thyroid hormones (T3 and T4) on leptin and IgE levels.To determine whether T3 and T4 alters serum leptin and IgE levels, twenty newly diagnosis hyperthyroidism patients,twenty asthma patients, ten asthma with hyperthyroidism patients and ten (healthy) as a control were studied. Serum samples were collected to measure the leptin and IgE levels in addition to T3,T4 and TSH Levels. The results revealed a significant (p<0.05) increase in leptin and IgE levels in hyperthyroidism, asthma and hyperthyroidism with asthma patients compared with the control group.These results indicated that elevation in T3 and T4 induced asthma,by affect

Methodology: A descriptive cross-sectional study a non-probability sampling method was used and a total sample collected was (126) ICU nurses Result: Moral distress among ICUs nurses were moderate and decision making was good Conclusion: Although nurses in ICUs perceive good decision making but suffered from moderate MD which affected their decision making. MD is still an important issue that nurses may face in ICUs Conclusion: Although nurses in ICUs perceive good decision making but suffered from moderate MD which affected the

The study aimed to explore the relationship between future anxiety and life orientation of male and female nurses, working in government hospitals of Gaza Strip governorates. The study sample consisted of 228 nurses (131 male nurses and97 female nurses. To achieve the study objectives , the researcher used the future anxiety scale, prepared by the researcher, and life orientation scale prepared by Scheier and Craver (1985 ) and translated into Arabic by Bader Al-Ansari . The results indicated that the level of future anxiety among nurses working at government hospitals was (64.85%), a high percentage, whereas life orientation was (65.96%), a low percentage. Additionally , the results showed that the Pearson correlation coefficient betwee

This formula was derived depending on some experimental data of transmittance spectrum versus wavelengths for many ambient temperatures. The extensive study of the spectrum characteristics and depending on Bose-Einstein distribution led to derive an equation connecting the extinction coefficient or the absorption coefficient with the ambient temperature and wavelengths of the incident rays. The basic assumption in deriving process is the decreasing in transmittance value with the increasing temperature which is only due to the changing in extinction coeffi

The operation of the OFET depends on two essential parameters: the insulation between the semiconductor layer and the gate electrode and the capacitance of the insulator. In this work, the electrical behavior of a pentacene-based OFET with a top contact / bottom gate was studied. Organic polyvinyl alcohol (PVA) and inorganic hafnium oxide (HfO2) were chosen as gate dielectric materials to lower the operation voltage to achieve the next generation of electronic applications. In this study, the performance of the OFET was studied using monolayer and bilayer gate insulators.
