Melatonin reduces acute lung inflammation, edema, and hemorrhage in heatstroke rats.
To assess the therapeutic effect of melatonin on heat-induced acute lung inflammation and injury in rats. ⋯ Melatonin may improve the outcome of heatstroke in rats by attenuating acute lung inflammation and injury.

Chronic ethanol consumption increases the levels of chemerin in the serum and adipose tissue of humans and rats.
Chemerin is a new adipokine involved in adipogenesis and insulin resistance. Since ethanol affects the insulin sensitivity that is closely associated with adipokines. The aim of this study was to investigate the effects of ethanol on chemerin in humans and rats. ⋯ Chronic ethanol consumption dose-dependently increases the chemerin levels in the serum and VAT. The serum chemerin level is associated with metabolic parameters in humans. The increased serum chemerin level is mainly attributed to an elevation of chemerin in the VAT after the ethanol treatment.

Associations between personality changes and nucleus accumbens ablation in opioid addicts.
It has been reported that nucleus accumbens (NAc) lesions can help to prevent relapse in opioid addicts. This article aimed to investigate associations between personality changes and NAc lesions. ⋯ Although the influence of other factors cannot be excluded, it is apparent that surgically induced NAc lesions are associated with lower P and N dimensions for opioid addicts, and a higher P dimension is associated with a tendency to relapse.

Inhibition of hypoxia inducible factor-1α ameliorates lung injury induced by trauma and hemorrhagic shock in rats.
Ischemia/reperfusion is an initial triggering event that leads to gut-induced acute lung injury (ALI). In this study, we investigated whether hypoxia inducible factor-1α (HIF-1α) played a role in the pathogenesis of lung injury induced by trauma and hemorrhagic shock (T/HS). ⋯ Local inhibition of HIF-1α by YC-1 alleviates the lung injury induced by T/HS. Our results provide novel insight into the pathogenesis of T/HS-induced ALI and a potential therapeutic application.

Glycyrrhizin attenuates rat ischemic spinal cord injury by suppressing inflammatory cytokines and HMGB1.
To investigate the neuroprotective effect of glycyrrhizin (Gly) against the ischemic injury of rat spinal cord and the possible role of the nuclear protein high-mobility group box 1 (HMGB1) in the process. ⋯ The results suggest that Gly can attenuate the transient spinal cord ischemic injury in rats via reducing inflammatory cytokines and inhibiting the release of HMGB1.
