OBJECTIVES To assess the value of serum interleukin (IL) 10 levels as an immunological marker in atopy and to determine the role of an IL-10RA gene single nucleotide polymorphism (SNP) (serine 138-to-glycine exchange [S138G]) in the pathogenesis of atopic diseases. METHODS Seventy-five patients with atopic disorders were compared with 25 age-matched(More)
Drug metabolizing enzymes participate in the neutralizing of xenobiotics and biotransformation of drugs. Human cytochrome P450, particularly CYP1A1, CYP2C9, CYP2C19, CYP3A4 and CYP3A5, play an important role in drug metabolism. The genes encoding the CYP enzymes are polymorphic, and extensive data have shown that certain alleles confer reduced enzymatic(More)
A single carboxyhaemoglobin (COHb) estimation of late evening blood sample among non-smokers, cigarette smokers, and sheesha smokers was evaluated among Saudis. The COHb level in smokers of 15 to 40 cigarettes a day ranged between 0.7 and 10.3 with a mean value of 6.1 +/- 2.58 COHb. Values among sheesha smokers ranged between 6.5 and 13.9 with a mean value(More)
The present study was conducted on 14 quadrants from seven solicited patients. After initial phase of plaque control, six different clinical parameters were recorded and scaling and root planning performed. In each of the seven patients two Modified Widman flaps were done. One served as a control and the other as experimental in which irrigation by(More)
OBJECTIVE This study investigated the use of three salivary microRNAs (miRNA-21, miRNA-184, and miRNA-145) as possible markers for malignant transformation in oral mucosal lesions. MATERIALS AND METHODS Salivary whole unstimulated samples were collected from a study group of 100 subjects, consisting of 20 clinically healthy controls, 40 patients with oral(More)
Genetic factors were recognized as possible predisposing factors in the etiopathogenesis of prepubertal periodontitis (PP). Consequently, the present work was carried out to determine the possible mode of inheritance and if there were any associated chromosomal aberrations in cases with PP. The study included 3 families with probands manifesting PP (the(More)
