Background: Bisphosphonates are potent inhibitors of bone resorption and were shown to inhibit bone resorption in experi- mental periodontitis by unknown mechanisms. We studied the effect of the aminobisphosphonate sodium alendronate (SA) in experimental periodontitis. Wistar rats were subjected to liga- ture placement around the second upper left molars. Methods: Animals were treated with SA 0.01 to 0.25 mg/kg...
Epidemiological aspects and the antimicrobial susceptibility profile of the Bacteroides fragilis group isolated from clinical and human intestinal specimens were examined in this study. B. fragilis group strains were isolated from 46 (37%) of 124 clinical specimens and the source of the samples was: Blood culture (3), intraabdominal infection (27), brain abscess (2), soft tissue infection (17), respiratory sinu...
