Abstract
Abstract Background and Objectives: Chromogenic media are the newest methods applied for rapid detection of pathogenic microorganisms in drinking water and food from 1998-2008. These Specific media contained the compounds acting as a substrate for microbial enzymes and, according to the type of enzyme, produce specific color. The aim of this study was to introduce the chromogenic media as a powerful tool in rapid detection of pathogenic agents in drinking water and food. Material and Methods: In this review article, the published papers about the use of chromogenic media in rapid detection of water and food-born pathogens were investigated. Results: The studies conducted in different countries show that the chromogenic media are very sensitive, specific and with high performance therefore, we can use it to detect the most important pathogenic microorganisms (such as Salmonella spp, E.coli, S.aureus, L.monocytogenes, and Candida spp.) in water and food samples. Conclusion: Because chromogenic media, in comparison with the other rapid detection methods such as PCR and ELISA, are very sensitive and cheaper, it can be applied as an alternative method. Key words: Chromogenic media, Rapid detection, water and food, Microorganism

Abstract
Abstract Background and objectives: Candida albicans is a normal flora in skin and mucosa and is not pathogen in normal individuals.The main defence against yeasts ,particulary Candida, is phagocytes, but phagocytesis and opsonization are reduced in thalassemia . the aim of this study was the determination of the frequency of Candida albicans and its species in the oral cavity of patients with major thalassemia and normal individuals. Material and Methods: This descriptive –analytic study was Conducted on 52 patients with major thalassemia and 104 normal individuals in Hamadan,2009. The specimens from oral cavity of the patients and control group were taken by sterile swab and then the direct exam and culture of all specimens were done Results: The Candida species in patients with thalassemia are Candida albicans (32.7%), tropicalis (13.5%) glaberata(10.5%), guilliermondii(10.9%) and Krusei(10.9%). In normal individuals,the frequency is 17.3%for albicans, 3.8% For tropicalis ,1% for glaberata and 1%for kefyr.Fifty-nine percent of the subjects undergone splenctomy and 23% of those with heathy Spleen have Candida in their oral cavity, this differene is statistically meaningful. Conclusion:The results show that suffering from thalassemia and spleenectomy can increase the possibitity of oral infection by Candida species. Key words: Major thalassemia,Candida albicans,Oral Cavity.

Abstract
Background and objectives: As a chronic inflammatory airway disease, asthma can increase level of markers of inflammation and muscle damage. In this study, we aimed to evaluate the effects of short-term continuous aerobic exercise combined with vitamin D supplementation on high-sensitivity C-reactive protein (hs-CRP), lactate dehydrogenase (LDH) and creatine kinase (CK) levels in asthmatic women.
Methods: In this study, 30 overweight (body mass index=26.97± 1.24 kg/m2) women with mild to moderate asthma were purposefully selected.. The subjects received a vitamin D tablet with a daily dose of 1000 IU for six weeks. The training protocol consisted of two sessions of Balke treadmill test (one session before and one session after the vitamin D supplementation). Blood samples were taken before and immediately after the exercise and before and after vitamin D supplementation. Repeated measures ANOVA was used to evaluate changes in the levels of hs-CRP, CK and LDH.
Results: The variables were not significantly affected by the exercise and vitamin D supplementation (P>0.05).
Conclusion: It seems that a single session of short-term aerobic exercise and six weeks of vitamin D supplementation do not significantly affect hs-CRP, CK and LDH levels in asthmatic women.
