Anhedonia is a core feature of major depressive disorder (MDD) and the limbic system has been indicated to be associated with anhedonia in MDD due to its crucial role within the reward circuit. However, the relationship between different regions of the limbic system and MDD, particularly anhedonic symptoms, remains unclear. Therefore, the purpose of this study was to investigate volume changes of various parts of the subcortical limbic (ScLimbic) system in MDD with and without anhedonia.

The number of previous episodes is one of the most crucial predictors of depression recurrence. However, the underlying neural mechanisms remain unclear.

However, few studies have focused on the structural changes in the hippocampus in major depressive disorder (MDD) patients with anhedonia. Meanwhile, considering that multiple and functionally specialized subfields of the hippocampus have their own signatures, the present study aimed to investigate the volumetric alterations of the hippocampus as well as its subfields in MDD patients with and without anhedonia.

However, the neuropathology of MDD is complex and the neural basis of anhedonia remains unclear. The aim of the present study was to investigate the impacts of anhedonia on brain functional alterations in patients with MDD.

Acute lung injury (ALI) is a life-threatening disease characterized by serious lung inflammation and increased capillary permeability, which presents a high mortality worldwide. Isofraxidin (IF), a Coumarin compound isolated from the natural medicinal plants such as Sarcandra glabra and Acanthopanax senticosus, has been reported to have definite anti-bacterial, anti-oxidant, and anti-inflammatory activities. However, the effects of IF against lipopolysaccharide-induced ALI have not been clarified.

The mice intragastric administration 75% (0.5 mL/100g) ethanol was pretreated with δ-amyrone (4 and 8 mg/kg) and cimetidine (100 mg/kg) or vehicles in different experimental groups for a continuous three-day, and animals were euthanized 3h after ethanol ingestion.
View Article and Find Full Text PDFIsofraxidin (IF), the major bioactive component of Sarcandra glabra, has been reported to be an effective anti-inflammatory compound. In a previous study, we showed that IF acts via the MAPK pathway to produce anti-inflammatory effects, both in vivo and in vitro. However, the effect and mechanism of action of IF on inflammatory cytokines and NF-κB activation in vivo has not been investigated.

Esculentic acid (EA), a triterpene compound extracted from the root of Phytolacca esculenta (the Chinese name Shang Lu), has been widely used to therapy a variety of inflammatory diseases such as rheumatoid arthritis, edema, hepatitis and bronchitis. The present study was designed to investigate the protective effects of EA against LPS-induced endotoxic shock by the intraperitoneal injection of EA (1, 5 and 10 mg/kg) prior to LPS stimulation (1 mg/kg, i.p.

The aim of this study was to evaluate the anti-inflammatory effect and the possible mechanisms underlying the anti-inflammatory activity of SG. Experimentally-induced mice ES model and LPS-induced peritoneal macrophages were used to examine the anti-inflammatory function of SG.

The present study aimed to investigate the anti-inflammatory effect of EA in vivo and in vitro and the effect of EA on cyclooxygenase (COX) protein expression. To gain insight into the anti-inflammatory effect of EA both in vivo and in vitro and its effect on COX-2 expression, we used animal inflammatory models and lipopolysaccharide (LPS)-induced mouse peritoneal macrophages to examine the anti-inflammatory action of EA.
