Objective: To investigate the correlation between the presence of a crown (CR) or a proximal restoration (PR) and furcation involvement (FI) on molars. Methods: Data were collected from 237 teeth in 44 patients who had restored and non-restored molars with or without FI.The clinical examinations were conducted on the molars including CR,PR,FI, mobility(MO), endodontic treatment(EN) and probe of periodontal attachment level(PAL). Results: Molars with CR or PR had a significantly highter percentage of FI (P0.05) when compared to molars without restorations. Conclusion: The molars with crowns or restorations involving the proximal tooth surfaces have a highter prevalence of FI and more periodontal attachment lose than molars without restorations.

The effects of magnolol (Mag) on hyperglycemia and hyperlipemia, hepatic oxidative stress and cytochrome P4502E1 (CYP2E1) activity of diabetic rats induced by high-fat diet (HFD) and streptozotocin (STZ) were studied. After oral administration of Mag (25, 50 and 100 mg x kg(-1) x d(-1)) for continuous 10 weeks, the blood glucose and lipids (TC, TG and LDL-C) levels, as well as the hepatic CYP2E1 activity and MDA content of diabetic rats, decreased significantly (P < 0.05 or P < 0.01), whereas the oral glucose tolerance and hepatic antioxidant enzymatic activities (CAT and GSH-Px) of diabetic rats, increased significantly (P < 0.05 or P < 0.01). The results indicated that Mag was effective against the hepatic oxidative damage, hyperglycemia and hyperlipemia of diabetic rats induced by HFD and STZ, and the inhibition of Mag on hepatic CYP2E1 activity could be an important mechanism of Mag against hepatic insulin resistance and oxidative damage.

Objective To understand the air microorganisms pollution and the community structure and distribution characteristics of outdoor airborne microbes in Xi'an in autumn.Methods Airborne microbes were sampled by fallen plates method in autumn,2006 in Xi'an at three typical sites,factories region,garden greenbelt region and main traffic region.Results The results showed that the total concentration of airborne microbes at the factories region and garden greenbelt region,main traffic region was 2 500 cfu/m~3,1 354 cfu/m~3 and 4 404 cfu/m~3 respectively.Bacteria and fungal genus were predominant.Gram positive bacteria were much more than Gram negative bacteria.There were 20 genera of bacteria and 8 fungal genus were detected. Micrococcui,Bacillus,Staphylococcus and Pseudornonus were predominant.The most frequently isolated fungal genus were Penicillium,Paecilomces,Cladosporium and Nonsporulatiny mycelia.The community structure of airborne fungal genus and the dominant genus in different function region was significantly different.The distribution characteristic of airborne microbe concentration in different function region was different.The concentration of airborne bacteria was significantly lower in garden greenbelt region than factories region and main traffic region,whereas the concentration of airborne fungi in garden greenbelt region was higher than that in factories region and main traffic region.Conclusion The distribution of the airbome microbes shows a characteristic of time and space,it is affected not only by the environment and pollution,but also by the other factors such as human activities,animals and plants.
