Abstract
Background and objectives: Diabetes is a chronic and progressive disease resulting in disability and premature death. The Etiology of diabetes mellitus is complex, but factors such as genetic, immunological and environmental are involved .The aim of this study was to investigate the association between diabetes and blood type.
Material and Methods: In this cross - sectional study blood group of 500 patients with diabetes type 2 was determined and compared with the distribution of blood groups in 11,461 healthy people in Ahwaz. Statistical analysis was performed by independent T test, using SPSS Software (version 17)
Results: the Patients’ age is between 35 and 80 years. Their Blood groups are A (106 20.3 %) B (144 27.5%) AB (97 18.5%) and O (176 32.7%). One hundred seventy-nine (34.2%) cases are Rh+ and the rest (344 65.8 %) Rh- .
Conclusion: Regarding to the distribution of blood group AB and Rh- ,which respectively are 7.3% and 8.4%, the chance of developing diabetes in theses people is higher than that in other people (P<0.05). Hence, they should follow a healthy lifestyle from early years of life to reduce the risk of diabetes.
Key words: Diabetes type 2, blood group, risk factors

Abstract
Background: Ulcerative colitis (UC) is a long-term inflammatory bowel disease (IBD) caused by abnormal immune responses, leading to inflammation and scarring in the large intestine. The bacteria Prevotella melaninogenica, found in the intestine and mouth, may contribute to UC. This study focuses on the detection of P. melaninogenica in the saliva of UC patients and compares them with the healthy control (HC) group.
Methods: The present study was a case-control study including 40 UC patients and 40 healthy controls (HCs) with an average age of 43.0 3± 10.3. This study used a real-time PCR test to investigate the frequency and average number of P. melaninogenica from the 16S rRNA gene sequence of P. melaninogenica in both groups.
Results: P. melaninogenica was more frequent in UC patients (77.5%) than HCs (45%) (p = 0.003). The patient group had more bacteria (339.31 ± 1082.29) than HCs (61.29 ± 154.03) (p = 0.005). Women in the UC group had more P. melaninogenica (492.35 ± 1427.61) than the control group (56.98 ± 123.50) (p = 0.0342). Similarly, men in the UC group (262.85 ± 664.97) had more bacteria than the control group (72.62 ± 222.76) (p = 0.015).
Conclusion: The current study showed that dysbiosis in P. melaninogenica, a bacterium in human saliva, could be important in the development of UC. Further investigation is needed to evaluate its use as a potential biomarker in the UC.
