Abstract

Context. Pleurotus ostreatus (P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae. Objectives The present study investigates the anti-inflammatory potential of P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae. Materials and Methods. Anti-inflammatory activity was evaluated using suspensions of freeze-dried and powdered (SFDP) P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae.

Dose-dependent inhibition of NO production was seen with Discussion and Conclusion. The promising activity of culinary mushroom P.o against inflammation suggests its potential application as a functional food during inflammatory conditions.P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae.

Highlights

  • Inflammation is a protective response to tissue injury which usually subsides after healing occurs [1]

  • Treatment with suspensions of freeze-dried and powdered (SFDP) P.o at doses of 500 mg/kg and 1000 mg/kg showed significant (P < 0.05) inhibition of paw oedema in diabetic rats when compared to the diabetic control group. e acetone extract (AE) of P.o (500 mg/kg) showed significant (P < 0.01) inhibition of paw oedema in diabetic rats after 1–5 hours. e anti-inflammatory effect exerted by the SFDP P.o at doses of 500 mg/kg and 1000 mg/kg and AE of P.o was comparable to indomethacin (P > 0.05). e SFDP P.o at doses of 500 mg/kg and 1000 mg/kg showed maximum inhibition of oedema of 70% whereas the AE of P.o showed maximum inhibition of oedema of 86% (P < 0.01)

  • Inhibition of carrageenan-induced inflammation has played a pivotal role in the development of Nonsteroidal anti-inflammatory drugs (NSAIDs) and COX inhibitors [28]. e inflammatory response of carrageenan-induced paw oedema

Summary

Introduction

Inflammation is a protective response to tissue injury which usually subsides after healing occurs [1]. During the process of inflammation, proinflammatory cells (macrophages and monocytes) release proinflammatory mediators, such as tumour necrosis factor-α (TNF-α), cytokines (interleukin (IL)-1 and IL-2), prostaglandin E2, and nitric oxide (NO) [2]. Increased expression and activity of cyclooxygenase (COX)-2 and inducible nitric oxide synthase (iNOS) play an important role in the inflammatory process [3]. In such cases, the defense reactions may cause tissue injury where anti-inflammatory drugs may be needed to overcome the inflammatory process. Nonsteroidal anti-inflammatory drugs (NSAIDs) which are COX-2 inhibitors are known to cause serious gastrointestinal disturbances including
