glycyrrhetic acid/hypersensitivity

Allergic rhinitis (AR) is caused by an IgE-mediated inflammatory reaction consequent to the exposure to the causal allergen. Glycyrrhetic acid (GlyAc) is a natural compound extracted from the liquorice that exerts anti-inflammatory activity. This real-life study compared intranasal GlyAc, present in

OBJECTIVE The aim of this work was to develop an elastic vesicular formulation to enhance the skin permeation of a poorly water-soluble 18β-glycyrrhetic acid (GA) and treat dermatitis. METHODS Elastic vesicles of GA were prepared by the film method with high pressure homogenizer and characterized by

The aim of this study was to develop a novel topical liposomal system entrapping 18β-glycyrrhetic acid (GA) for the treatment of chronic allergic dermatitis. A novel liposomal system with molar ratios of GA to lysine from 1:1 to 1:3 was prepared by high-pressure homogenization. The liposomes at the

To clarify the feasibility of medicinal use of the cultivated Glycyrrhiza resources, the equivalency between the G. uralensis roots cultivated in eastern Nei-Meng-Gu of China and medicinal licorice (Glycyrrhizae Radix, Gancao in Chinese and Kanzo in Japanese) was examined. The HPLC fingerprint

Liquorice has been used for allergic-inflammatory and liver disorders in both traditional Chinese and modern medicine. In traditional Chinese formulations, it is mainly roasted liquorice that has been used rather than un-roasted liquorice. We have compared the pharmaceutical characteristics of

Introduction: High mobility group protein box 1 (HMGB1) is a protein belonging to the alarmin family. HMGB1 has a relevant role in starting the inflammatory cascade by means of receptors, such as RAGE and TLR. HMGB1 supports transcription of many genes in interactions with many transcription

Introduction This study is a systematic review on recent developments about the importance of HMGB1 protein in the pathogenesis of rhino-sinusal inflammatory diseases. We also report data on the use of 18-β-glycyrrhetic acid (GA), which has been shown able to inhibit the pro-inflammatory activities

Glycyrrhizin (GL) is known to have various immunomodulating activities and has long been used clinically as an anti-allergic and anti-hepatitis agent. While the potency of GL against lung inflammatory diseases has been expected, the effect of GL on the lung has been poorly understood. Lung

BACKGROUND Bradykinin (BK) has many biological effects in inflammation, allergy, and septic shock. Studies have shown that low doses of BK can induce vascular relaxation and high doses can induce vascular contraction in many pathophysiological conditions, but the role and mechanisms that high doses
