Association of a genetic variant (rs689466) of Cyclooxygenase-2 gene with chronic periodontitis in a sample of Iraqi population
...Show More Authors

Background: periodontitis is a chronic inflammatory disease causing destruction of the tooth supporting structures, initiated by dental plaque and modified by environmental and genetic risk factors. Cyclooxygenase-2 (COX-2) enzyme is responsible for the production of prostaglandin E2, an important mediator in the chronic periodontitis (CP) pathogenesis. Polymorphisms in COX-2 gene have linked to CP in different populations. Aim: To study the association between Cyclooxygenase-2 single nucleotide polymorphism rs689466 (-1195A/G SNP) and chronic periodontitis in a sample of Iraqi population. Methods: One hundred Iraqi subjects divided into two groups: case group consisted of 70 CP patient (35 males and 35 females) with age range 30-55 years, and control group consisted of 30 racially matched healthy subjects (15 males and 15 females) with age range 30-50 years. Clinical periodontal parameters including plaque index (PLI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD) and clinical attachment level (CAL) were recoded for all participants. 3ml of venous blood was collected from each participant for isolating genomic DNA. Genotyping of the rs689466 in COX-2 gene was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Results: The frequency of G allele carriers was significantly more prevalent in the case group compared to control group (P= 0.041), and allele G was associated with greater susceptibility for chronic periodontitis compared to allele A (OR=1.4). Conclusion: COX-2 (rs689466) polymorphism may be associated with increased chronic periodontitis susceptibility.

In vivo histological evaluation of the effect of the topical application of estrogen hormone on wounds healing in ovariectomized rabbit
...Show More Authors

Background: Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. Growth factors released in the traumatized area promote cell migration into the wound area (chemotaxis), stimulate the growth of epithelial cells and fibroblasts (mitogenesis), initiate the formulation of new blood vessels (angiogenesis), and stimulate matrix formation and remodeling of the affected region. One of factors that effects on wound healing is a sex hormones and one of these hormones is an estrogen hormone. A wide range of cutaneous cell types (eg, fibroblast, endothelial, epithelial, and inflammatory) expressed estrogen receptors, in

Evaluation of the effectiveness of the crude juice of Olive (Olea europaea) in reducing the percentages of chromosomal aberration and micronuclei in albino mice
...Show More Authors

This research was carried out to evaluate the activity of crude juice of Olive on some cytogenetic parameters in mice like chromosomal aberration (CAs) and micronuclei formation(MN). The results showed that there was no significant difference between the crude juice (green and black)in CAs(3.77,4.10)and MN(0.25,0.25) in comparison with negative control (3.39,0.22)respectively. The interaction effect between the crude before and after treatment with mutagen MMC showed that the crude is one of the vital inhibitors of the mutagen by its ability in reducing the percentages of both the CAs and MN in bone marrow cells in mice.
