Effects of technetium-99 methylenediphosphonate on cytokine-induced activation of retro-ocular fibroblasts from patients with Graves' ophthalmopathy.

Objective: To explore the effects of technetium-99 methylenediphosphonate (99Tc-MDP) on cell proliferation, hyaluronic acid (HA) synthesis and the expressions of human leucocyte antigen-DR (HLA-DR), intercellular adhesion molecule-1 (ICAM-1) on cultured retro-ocular fibroblasts (RFs) from patients with Graves' ophthalmopathy.

Methods: After two to seven passages, cultured RFs were incubated for 72 h with interferon-γ (100 U/ml), interleukin-1 (100 U/ml) or tumour necrosis factor-α (100 U/ml) in the presence of 99Tc-MDP. Flow cytometry was used to investigate the expression of HLA-DR and ICAM-1.

[Anti-depressive effect of Baisong tablets on the chronic mild unpredicted stress depression in rats].

Objective: To investigate the effect of Baisong tablets on the nerve-biochemistry and neuroendocrine of chronic mild unpredicted stress depression in rats.

Methods: Sixty male Sprague-Dawley rats were randomly allocated to 4 groups: a normal control (NC), a model control (MC), a fluoxetine control (FC) and a Baisong tablet treatment group (BST). All rats except the control group were singly housed and exposed to an unpredicted sequence of mild stressor.
