Abstract

The aim of the study was to evaluate the antioxidant, immunomodulatory and anti-arthritic effects of turmeric extracts (Standard and CurQfen) on rat adjuvant arthritis. The impact of the treatment was investigated on pro- and antioxidant status, serum interleukins IL-17 and IL-1β, blood indices, joint swelling, and histological changes in the joints, liver and body weight. Both turmeric extracts improved blood indices, decreased the level of pro-inflammatory cytokines, and enhanced antioxidant level. Both extracts diminished swelling and normalized histological structure in soft periarticular tissues, synovial membrane and hyaline cartilage. No negative effect on the liver was observed. CurQfen was more effective than Standard extract. The strong antioxidative, anti-inflammatory and immunomodulatory effects of the turmeric extracts suggest their usefulness in the treatment of autoimmune arthritis as monotherapy or in combination with traditional anti-arthritic drugs.<br />Cilj ovoga istraživanja bio je procijeniti antioksidacijske, imunomodulacijske i antiartritične učinke ekstrakta kurkume (standardni i CurQfen) na štakore s adjuvantnim artritisom. Istražen je utjecaj ekstrakta kurkume na prooksidacijski i antioksidacijski status, serumske interleukine IL-17 i IL-1β, krvne pokazatelje, otekline zglobova i histološke promjene u zglobovima i jetri te na tjelesnu masu. Oba su ekstrakta kurkume dovela do poboljšanja krvnih pokazatelja, smanjila su razine proupalnih citokina i poboljšala antioksidacijski status. Također su oba ekstrakta kurkume smanjila otekline i normalizirala histološku strukturu u mekim periartikularnim tkivima, sinovijskoj membrani i zglobnoj hrskavici. Nije zapažen negativan učinak na jetru. CurQfen je bio učinkovitiji od standardnog ekstrakta. Jaki antioksidacijski, protuupalni i imunomodulacijski učinci ekstrakta kurkume pokazuju da on može biti koristan u liječenju autoimunosnog artritisa kao monoterapija ili u kombinaciji s tradicionalnim lijekovima za liječenje artritisa.
