Resveratrol protects renal damages induced by periodontitis via preventing mitochondrial dysfunction in rats.

Objectives: Periodontitis is closely associated with kidney disease and reactive oxygen species (ROS) involvement. Mitochondria are the primary source of both endogenous ROS and renal energy. We investigated whether resveratrol (RSV) prevents renal injury and mitochondrial dysfunction in periodontitis rats.

Carnosol protects against spinal cord injury through Nrf-2 upregulation.

Background: Carnosol is an ortho-diphenolic diterpene with excellent antioxidant potential. The present study was designed to identify the protective role of carnosol against spinal cord injury (SCI)-induced oxidative stress and inflammation in Wistar rats.

Methods: In the present study, oxidative stress status was determined through estimating total antioxidant capacity, total oxidant status, lipid peroxide content, protein carbonyl and sulfhydryl levels, reactive oxygen species (ROS), antioxidant status (superoxide-dismutase, catalase, glutathione, glutathione peroxidase, glutathione-S-transferase).

[Evaluation of the public on the psychosocial effects of fluorosis].

Objective: To explore the attitude of the public to the psychosocial effects of fluorosis through investigating the public in different areas.

Methods: Twenty typical fluorosis photos were selected and evaluated by the public in Xingtai, Beijing and Guangzhou, which included 101 dentists, 118 dental students, 103 college students in non-dental schools, 102 clerks and 92 leaders. Each evaluator was required to answer seven five-point questions according to each photo.

[Evaluation of the psychosocial status of fluorosis patients in fluorosis epidemic areas].

Objective: To explore the psychosocial effect of fluorosis on patients in fluorosis epidemic areas.

Methods: Multistage, stratified, clustered and random sampling method was used in this survey. Totally 416 inhabitants of 12, 15 and 35-44 years of age from rural fluorosis epidemic areas in Hebei province were selected.
