NADPH oxidase-dependent HO production mediates salicylic acid-induced salt tolerance in mangrove plant Kandelia obovata by regulating Na/K and redox homeostasis.

Salicylic acid (SA) is known to enhance salt tolerance in plants. However, the mechanism of SA-mediated response to high salinity in halophyte remains unclear. Using electrophysiological and molecular biological methods, we investigated the role of SA in response to high salinity in mangrove species, Kandelia obovata, a typical halophyte.

Brassinosteroid enhances salt tolerance via S-nitrosoglutathione reductase and nitric oxide signaling pathway in mangrove Kandelia obovata.

Brassinosteroid (BR) has been shown to modulate plant tolerance to various stresses. S-nitrosoglutathione reductase (GSNOR) is involved in the plant response to environment stress by fine-turning the level of nitric oxide (NO). However, whether GSNOR is involved in BR-regulated Na /K homeostasis to improve the salt tolerance in halophyte is unknown.

[Effect of Electroacupuncture Stimulation of "Guanyuan" (CV 4) and "Zusanli" (ST 36) on Spleen Lymphocytes Treg/Th 17 Immune Balance in Ulcerative Colitis Mice].

Objective: To observe the effect of electroacupuncture (EA) intervention on spleen T-helper 17 (Th 17) and regulatory T (Treg) cell levels in mice with ulcerative colitis (UC), so as to reveal its mechanisms underlying improvement of UC. METHODS Kunming mice were randomized into control, UC model and EA groups, with 8 mice in each group. The UC model was established by giving the mice with 3% Dextran Sulfate Sodium (DSS) for 5 days.

[Effect of pentoxifylline on the expression of hepatic TGF-beta 1, type I and type III collagen in mice with liver fibrosis due to Schistosoma japonicum infection].

Objective: To study the effect of pentoxifylline (PTX) on the content of hepatic TGF-beta 1, type I and type III collagen in schistosome-infected mice with liver fibrosis.

Methods: Forty mice with schistosomiasis were divided into four groups: one group as control without any treatment, other three were treated with praziquantel 500 mg/(kg.d) for 2 d, high dose PTX 360 mg/(kg.
