Abstract:
Objective To analyze the effect of astragalus polysacharin (APC) on bone resorption in experimental periodontitis, and evaluate its protective function of inflammatory resorption of alveolar bone in periodontits. Methods SD rats were randomly divided into five equal groups: contorol group, model group, and APC low [LD: 100 mg/(kg∙d)], medium [MD: 200 mg/(kg∙d)], and high dose [HD: 500 mg/(kg∙d)] treatment groups. The periodontitis models were established through Porphyromonas gingivalis attracting. APC [LD: 100 mg/(kg∙d); MD: 200 mg/(kg∙d); HD: 500 mg/(kg∙d)] gavage was given to treatment groups, and the same amount of normal saline was given to control and model groups. The rats executed after four weeks, their CEJ-ABC distance (CAD) and expression of IL-1β, IL-6, TNF-α, TOS, TAS, RANKL, OPG in their serum was evaluated, and the oxidative stress index (OSI) was calculated. Results As APC amount increased, CAD, TOS, and OSI levels were declined significantly; While TAS, RANKL, RANKL/OPG levels were improved significantly; There was no significantly change on IL-1β, IL-6, TNF-α, and OPG levesl among groups. Conclusion APC prevents alveolar bone from oxidative stress and inflammatory damage by down-regulating OSI and RANKL/OPG.
