The Research Trends of Pharmacopuncture Therapy on Cervical Pain Caused by Traffic Accidents.

Objectives: The purpose of this study is to comprehensively review Korean domestic studies and investigate the research trends of pharmacopuncture therapy on cervical pain caused by traffic accidents.

Methods: Domestic studies between February 1999 and May 2020 from four Korean databases were searched with combinations of keywords 'cervical pain', 'traffic accident', 'whiplash injury', and 'pharmacopuncture'.

Results: 17 studies were selected for review, including 7 randomized controlled trials, 5 retrospective observational studies, 3 case reports, and 2 non-randomized controlled trials.

Effects and action mechanisms of Korean pear (Pyrus pyrifolia cv. Shingo) on alcohol detoxification.

Korean pear (Pyrus pyrifolia cv. Shingo) has been used as a traditional medicine for alleviating alcohol hangover. However, scientific evidence for its effectiveness or mechanism is not clearly established.

Electroacupuncture induces Fos expression in the nucleus tractus solitarius via cholecystokinin A receptor signaling in rats.

Objectives: Cholecystokinin, a satiety hormone, acts on cholecystokinin A receptor on vagal afferent neurons that project to the nucleus tractus solitarius, resulting in inhibition of feeding. Cholecystokinin is known to be released by electroacupuncture stimulation at certain body sites which elicits profound psychophysiological responses. Our previous study has revealed the involvement of cholecystokinin and cholecystokinin A receptor in the electroacupuncture stimulation-induced modulation of feeding.

Flavonol-rich RVHxR from Rhus verniciflua Stokes and its major compound fisetin inhibits inflammation-related cytokines and angiogenic factor in rheumatoid arthritic fibroblast-like synovial cells and in vivo models.

Rheumatoid arthritis (RA) is an aggressive inflammatory disease in which cytokines/chemokines are thought to recruit leukocytes and induce angiogenesis. The aim of this study is to investigate the effect of flavonol-rich residual layer of hexane fraction from Rhus verniciflua Stokes (RVHxR) and its major compound fisetin on inflammatory cytokine/chemokine production and angiogenic factor in IL-1beta-stimulated RA fibroblast-like synovial cells (FLS) and inflammatory in vivo models. Flavonol-rich RVHxR and its major compound fisetin significantly inhibited IL-1beta-induced FLS proliferation in a dose-dependent manner.

The endogenous CCK mediation of electroacupuncture stimulation-induced satiety in rats.

A major satiety hormone, cholecystokinin (CCK) is well known to be released by electroacupuncture (EA) stimulation at certain body sites which elicits profound psychophysiological responses. Previous clinical and animal studies have shown that EA stimulation reduces food intake and body weight in both normal and obese subjects. The aim of the present study was to elucidate the satiety effect of EA stimulation and its mechanism related to CCK in rats.
