This study investigated the influence of the histamine H1 receptor antagonists, chlorpheniramine (CHL) and pyrilamine, on the analgesic effects of acupuncture in mice. Nociceptive response was evaluated by the acetic acid-induced abdominal writhe test. Electroacupuncture (EA) at bilateral ST36 reduced the manifestations of acetic acid-induced abdominal writhing, whereas needle insertion without electrostimulation had no such effect. Notably, EA treatment was not associated with any analgesic effects in mice pretreated with naloxone...

Skin injury is a major complication during radiation therapy and is associated with oxidative damage to skin cells. An effective and safe radioprotectant to prevent this skin damage is still unavailable. The Rhodiola crenulata root extract (RCE) has been reported to be a free radical scavenger and a potent anti-oxidant in both in vitro and in vivo models. In the current study, we investigated the effects of RCE on ionizing radiation-induced skin injury and its underlying mechanisms. HaCaT cells - a non-cancerous skin cell line together with HepG2, Caco2, A549, and OECM cancer cell lines - were pre-treated with RCE for 24[Formula: see text]h followed by exposure to 15 Gy using Caesium-137 as a γ-ray source...

oxLDL is involved in the pathogenesis of atherosclerotic lesions through cholesterol accumulation in macrophage foam cells. Andrographolide, the bioactive component of Andrographis paniculata, possesses several biological activities such as anti-inflammatory, anti-oxidant, and anticancer functions. Scavenger receptors (SRs), including class A SR (SR-A) and CD36, are responsible for the internalization of oxLDL. In contrast, receptors for reverse cholesterol transport, including ABCA1 and ABCG1, mediate the efflux of cholesterol from macrophage foam cells...

The high incidence of tuberculosis (TB) in developing countries, the resurgence of TB in industrialized countries, and the worldwide increase in the prevalence of Mycobacterium avium complex infections have prompted the quest for new antimycobacterial drugs. However, the development of such chemotherapeutics is currently making very slow progress. It therefore appears that devising improved administration protocols for clinical treatment against intractable mycobacteriosis using existing chemotherapeutics is more practical than awaiting the development of novel antimycobacterial drugs...
