Background:Ovulation constitutes a central event in ovarian physiology, and ovulatory dysfunction which is a relevant cause of female infertility. Mammalian ovulation is comparable to aninflammatory reaction since many of the molecules responsible for inducing the inflammatorycascade including PGs, leukotrienes and various cytokines have been describedin the ovary.
Objectives:This study was designed to compare between the effects of some NSAIDs(aspirin,diclofenac sodium and meloxicam)on the ovulatory process and the reproductive tract of female mice.
Materials and methods:Twenty four female mice were subdivided into 4groups (6 animals/group).The first received distilled water serve as control group, the second receivedaspirin (7.5 mg/kg.B.W) ,thethird received diclofenac sodium(2mg/kg.B.W) and the fourth received meloxicam(0.001mg/kg.B.W) subcutaneously at proestrous phase,Blood was collected at metestrousfor subsequent hormonal assay. The whole reproductive tract was excised out, examined, weighed and ova were flushed.
Results :Female mice that received 7.5 mg/kg.B.W of aspirin,showedenlarged, congested ovaries with cystic appearance and congested uteri with prominent blood vessels.Mice that received 2mg /kg.B.W.diclofenac and those received 0.01 mg/kg.B.W. meloxicam showed more congestion and more obvious cystic appearance of ovaries with uteri more bulky compared to controls that showed no congestion and no cystic appearance of the ovaries with thin non congested uteri.Highly significant (P < 0.001) increase in the ovarian weight and highly significant decrease in number of ova flushedwhile no significant changes (P > 0.05) were seen in the uterine weight nor in hormonal levels of LH and FSH between controls and each of animals that received aspirin, diclofenac and meloxicam respectively.
Conclusion:Short -term administration of low-dose (aspirin, diclofenac& meloxicam) to female mice at proestrous cause a highly significant increase in the ovarian weight with morphological changes of ovaries and uteri and a highly significant decrease in the ovulatory rate as compared to controls .Greater effect were produced by meloxicam with a lower dose compare to diclofenac and aspirin.

Because it differs in internal music, and we seek in this research to shed light on the internal music in the book The Young Branches of Ibn Saeed Al-Andalusi, in terms of the poets' choice of words and styles that make up the internal music
Abstract
The current research aims to identify the effectiveness of concept maps in the academic achievement of the art of elegance and fashion for third vocational students. The current research is a quasi-experimental one. The research sample consisted of (74) female students in Al-Saydiyah secondary school for girls, they were divided into two groups: the experimental group and the control group. The following hypothesis was developed: There are no statistically significant differences at the level (0.05) between the average scores of the students who studied the subject using concept maps and the average scores of the students who studied the subject in the traditional method in the post-achievement test. The

monitor, analyze and produce maps of changes in land use and land cover in the district of
Mahmudiya in Baghdad during the period 1990-2007 using the applications of remote sensing
techniques and with the assisstant of geographic information systems (GIS),as a valuable
contribution to land degradation studies.
This study is based maiuly on the processing on two subsets of landsat5 TM images picked up
in August 1990 and 2007 respectively in order to facilitate comparision and were thengeometrically and radiometrcally calibrated ,to used for digital classification purposes using

Basically, this study aims to identify the extent to which Iraqi secondary school students use writing strategies and how proficiency level and students gender could affect writing strategy use. The study also examines the relationship between writing achievement and writing strategy use among Iraqi secondary school students. For this purpose, 140 Iraqi secondary school students were selected randomly from six different schools. Petric and Czarl’s questionnaire (2003) was adopted in the study as an instrument to collect the needed data. A software of SPSS used to analyze the collected data. The findings revealed that secondary school students appeared as low users of writing strategies; low proficient students do not show a sta

This study presents a mathematical model describing the interaction of gut bacteria in the participation of probiotics and antibiotics, assuming that some good bacteria become harmful through mutations due to antibiotic exposure. The qualitative analysis exposes twelve equilibrium points, such as a good-bacteria equilibrium, a bad-bacteria equilibrium, and a coexisting endemic equilibrium in which both bacteria exist while being exposed to antibiotics. The theory of the Sotomayor theorem is applied to study the local bifurcation around all possible equilibrium points. It’s noticed that the transcritical and saddle-node bifurcation could occur near some of the system’s equilibrium points, while pitchfork bifurcation cannot be accrued at

An important part of the etiology of diabetes and diabetic retinopathy is played by oxidative stress. Malondialdehyde is a dialdehyde that is moderately toxic and is frequently used as a marker for oxidative stress as well as lipid peroxidation.
Objectives: To assess the serum malondialdehyde levels in diabetic patients with and those without retinopathy and to compare these levels to controls .In additions to, investigate the relationship between serum malondialdehyde level and long glycemic control, the glycated hemoglobin (HbA1c).

Background: Osteoarthritis (OA) currently seems
inevitable and unavoidable for a large swath of the
population .its etiology relates to a strong ,but
complex ,non mendelian genetic basis ,combined
with mechanical and metabolic factors that cause
molecular alterations the end results of which
affect the whole joint .Glucosamine and
chondrotin sulfate alone or in combination may be
of benefit to a subgroup of individuals who have
knee pain due to OA.
Glucosamine has been shown to alter cartiage turn
over in patients with OA undergoing physical
training
Aim of the study: To find the validity of
glucosamine chondrotin sulfate in treatment of
grade 1 and 2 OA.
Methods: the sample of 280 patients
