Journal of University of Anbar for Pure Science , volume:8 issue:2

The antifungal activity of different concentration of natural honey , synthetic honey and sugar syrup were examined against ten strains Candida albicans that isolated from saliva of patients with dentil caries and gingival ulcer . The antifungal test was done by agar dilution method by adding honey to the agar after sterilization . The concentrations used in this study of all sample were ranged from (10%-85%) (w/v) The natural honey MIC that inhibited C. albicans growth ranged from (20%-40%)(w/v%) . A synthetic honey and sugar solution was also tested to determine antifungal activity attributable to sugars. C. albicans was more resistant against the presence of synthetic honey and sugar syrup in the culture medium at concentrations above 70% (w/v%) . What the data suggests is that the component in the honey responsible for the observed antifungal in vitro properties is not sugar based. Honey might be tapped as a natural resource to look for new medicines for the treatment of mycotic infections. This could be very useful, onside ring the increasing resistance of antifungal.

Journal of University of Anbar for Pure Science , volume:8 issue:2

ROS are highly toxic to all types of biological molecules including DNA, lipids, protein and carbohydrates, and ROS considered as a cause of much disease including genital diseases. The study consists of 72 infertile with different categories (Oligozoospermia, Asthenozospermia and Normozoospermia) and 24 healthy men as control in the period from March to November 2012. Patients were selected and analyzed according to WHO 2010. The following biochemical parameters have been examined for each sample (net semen ROS (Reactive oxygen species), washed Sperm ROS Lipid Peroxidation and DNA damage level). Result show a significant increase in ROS, Lipid peroxidation, DNA damage in different groups infertile men compared to fertile, while no significant difference in washed spermatozoa ROS level. Low sperm count in Oligozoospermia group may be due to apoptosis process in the testes activated by high level of ROS. The link between ROS and reduced motility may be due to the decrease in axonemal protein phosphorylation and sperm immobilization. Lipid peroxidation in Normozoospermia infertility occurs in a high level in the sperm acrosome, leading to loss of the ability to penetrate the ovum.
