Structural and functional brain changes in early- and mid-stage primary open-angle glaucoma using voxel-based morphometry and functional magnetic resonance imaging.

To investigate structural and functional brain changes in patients with primary open-angle glaucoma (POAG) by using voxel-based morphometry based on diffeomorphic anatomical registration through exponentiated Lie algebra (VBM-DARTEL) and blood oxygenation level dependent functional magnetic resonance imaging (BOLD-fMRI), respectively.Thirteen patients diagnosed with POAG and 13 age- and sex-matched healthy controls were enrolled in the study. For each participant, high-resolution structural brain imaging and blood flow imaging were acquired on a 3.

[Therapeutic effect of emodin in experimental periodonititis rats].

Aim: Through observing the change of Nitric Oxide (NO) in the peripheral blood and gingival tissue, to explore the mechanism of Emodin (EMD) in the therapy of periodontal disease.

Methods: SD rats were randomly divided into four groups of thirty (group N, group P, group PL and the group PH). The periodontitis model was made and EMD was administered at PL and PH.
