In this study, the microbe's pollution of sewage, wastewater and several wells around Yazd were measured. Our study includes counting aerobic mesophilic bacteria, Coliforms and E.coli. Then the microbial resistance of the sample to ray was determined as D10 value and the optimum dose obtained to meet the desired level of pollution and disinfection the wastewater. Also, Salmonella detection tests before and after irradiating was performed on the samples. We were used irradiation method by Electron beam to decrease bioburden. Also BOD and COD of wastewater were measured and shown that BOD and COD were been decreased after irradiation regularly.<\div>

Transdermal systems are among Novel Drug Delivery Systems and are attributed to the systems havingproperty of diffusing drugs through skin in a noninvasive form by delivering drugs into systemic bloodcirculation which as a consequence the drug effects appears. Within two pervious decades, transdermaldrug delivery has been the core of interest of many pharmaceutical research and chemical and polymerengineering studies. Constant blood level, non–hepatic first pass effect, patience compliance areadvantages of these systems compare to oral administration and intravenous infusion. The greatestlimitation in developing these systems is impermeability of stratum corneum. This study targeted toDesign & In–vitro evaluation of Transdermal Drug Delivery System for Nitroglycerin for thetreatment of angina pectoris. Permeation enhancers under study were various kinds of hydrophils andhydrophobs. Oleic acid and cetyl alcohol from hydrophobs and propylene glycol from hydrophils wereselected. Drug–in–adhesive patches were studied from point of view of dissolution method. Finally therelease profile of nitroglycerin from different drug–in–adhesive patches containing different pressuresensitive adhesives and chemical permeation enhancers were determined. The conclusion was thatrelease profile of nitroglycerin from different formulations depends on viscosity and type of pressuresensitive adhesive and type and concentration of selected chemical permeation enhancer.<\div>

Background: Cystic fibro sis (CF) is a common genetic disorder chiefly characterized by respiratory andgastrointestinal symptoms. The purpose of this study was to evaluate the clinical presentation and growthstatu s in CF patients at the time of diagnosis and following conventional treatment.Materials and Methods: A cro ss–sectional study was conducted on 67 CF pat ients who enrolled for at leasta two–year follow up period in the CF Clinic ofSarvar Pediatric Hospital. Disea se diagnosis was based ona positi ve sweat test. Growth indicators and initial clinical presentations of patients were registered at thetim e of diagnosis. Weight and height was measured at each clinical visit during follow up. All patients weretreated with enzyme replacement, vitamin and mineral supplements. Other medication s were prescribed asclinically indicated. Statistical analyses were performed by SPSS 16.0 for MS Windows.Results: The mean age of patients was 24.9±37.7 months at the time of diagnosis, whereas it was 3.1±2.1months at the onset of CF symptoms. At diagnosis, the majority of CF patients suffered from malnutrition,growth failure, and presented with pulmonary and gastrointestinal symptoms. After conventional and nutritionaltreatments, significant improvements were seen in weight and height.Conclusion: A delay in the diagnosis ofCF as seen in our country causes patients to further suffer from malnutritionand growth failure in comparison to developed countries. This emphasizes the necessity of neonatalscreening. The results of this study show the dramatic effects of nutritional treatment on growth status
