    Effect of usage of mobile phone in trouser pocket on quality of semen parameters
    (Faculty of Graduate Studies, University of Kelaniya, 2015) Munasinghe, D.A.L.; Weerasooriya, M.K.B.; Liyanage, J.A.; Wakkumbura, H.P.
    A cross sectional study was carried out in the fertility clinic of Gampaha Wickramarachchi Ayurveda hospital during the period of August 2014 to August 2015 to find out the effect of carrying mobile phone in trouser pocket on the quality of semen parameters. Mobile phone has become an essential instrument among the lives of modern society. It assists to globalize the world. The disadvantage is the emitting of harmful rays when it‘s in use or switch on mode. However this bad effect basically depends on the way of handling the item. In vitro studies in foreign countries have shown that mobile rays have a negative effect on sperm motility. However, local studies on subject are handful in amount. Thus the current study was set up to trace the effect of switch on mobile phones kept in trousers on semen parameters. Every male who visited the clinic for fertility issue was personally evaluated on consent to gather the behavioral data. The semen of each was also collected (after 3 days absent from ejaculation) and analyzed separately. Out of 81 subjects 51 were used to carry the phone in trouser pocket as a custody. However when comparing the average semen parameters of them such as volume, sperm count, sperm motility and morphology with the same of non-users, it was clear that though there was a slight reduction of mentioned parameters in the test group it was statically not significant (P>0.05). Thus according to the final result the usage of mobile phone in trouser has a less effect on the quality of semen parameters. However this could be due to non-continuous usage of switch on mobile phone in the particular site. More over its better to keep the phone out of the site of testis when concerning male fertility.

    Antibacterial activity of extract of leaves of Atalantia ceylanica (Yakinaran)
    (Faculty of Graduate Studies, University of Kelaniya, 2015) Munasinghe, D.A.L.; Karunarathna, E.D.C.; Sudesh, A.D.H.
    Antibacterial activity of leaves of Atalantia ceylanica was tested qualitatively against 05 bacterial strains with the modified plate method at Gampaha Wickramarachchi Ayurveda Institute. The steam of boiled leaves and extract are used by certain villagers as a traditional treatment for healing respiratory ailments such as influenza. Even though natural flora may be effective in curing health defects, scientific studies on subject is limited. Thus the study was arranged to fill the gap for certain extent to harness natural resources effectively in health. So as the study was aimed to investigate the antibacterial properties of Atlanta leaves. The plates, prepared with the watery extract of boiled leaves, which comprised of neat concentration of raw leaf materials and Mueller-Hinton agar were inoculated with laboratory stored standard bacterial strains including Pseudomonas aeruginosa, Streptococcus pneumonia, Escherichia coli, Staphylococcus aureus and Methicillin resistant Staphylococcus aureus separately, which can cause respiratory as well as gastro- intestinal symptoms. For the control test, distilled water was used to make plates instead of watery leaf extract. Even after the duplicated experiment, no strain was found to be inhibited by the leaf materials, which indicated that the neat concentration of raw chemical compound of particular leaves have no inhibitory action on tested strains. As the respiratory infection is not only caused by bacteria but also by viruses, perhaps phytochemicals might have possessed antiviral as well as antibacterial properties on organisms other than the tested strains. Occasionally the chemicals of the particular plant leaves might have possessed certain antiinflammatory features to control respiratory symptoms. Nevertheless it was clear that the chemical compounds of the distillation of leaves of Atalantia ceylanica had no significant inhibitory effect on the growth of tested strains. The same experiment was carried out early for the steam of particular leaf and the results were found to be the same.
