OBJECTIVE Despite the recognized anti-inflammatory potential of heterocyclic antidepressants, the mechanisms concerning their modulating effects are not completely known. Thus, we evaluated the anti-inflammatory effect of amitriptyline, clomipramine, and maprotiline and the possible modulating properties of these drugs on neutrophil migration and mast cell degranulation. METHODS The hind paw ...

A carrageenan-degrading marine Cellulophaga lytica strain N5-2 was isolated from the sediment of carrageenan production base. A κ-carrageenase (EC 3.2.1.83) with high activity was purified to electrophoretic homogeneity from the culture supernatant by a procedure of ammonium sulfate precipitation, dialyzing and gel filtration on SephadexG-200 and SephadexG-75. The purified enzyme was verified a...

The species of Asteraceae were used traditionally in treatment of inflammatory disorders. The present study aimed to assess the anti-inflammatory effect of methanolic extract of aerial parts of Rhanterium epapposum Oliv. (R.epapposum), Achillea fragrantissima (Forssk.) Sch.Bip (A. fragrantissima), Artemisia herba-alba Asso. (A.herba-alba), Echinops spinosus L. (E. spinosus) and Echinops hussoni...

In this study, we aimed to investigate the peripheral antinociception effects of specific phosphodiesterase 5 (PDE-5) inhibitor vardenafil on carrageenan-induced nociception in rats, and the role of calcium besides the L-arginine- nitric oxide (NO)- cyclic guanosine monophophate (cGMP) pathway in these effects. Hyperalgesia was induced by the intraplantar injection of 0.1 mL fresh carrageenan s...

Since antiquity piperine has been widely used in Indian traditional medicine. Piperine is an alkaloid isolated from the fruit of Black pepper. To compare the anti-inflammatory property of Piperine with standard as hydrocortisone against Carrageenan induced paw edema model in albino rats. After approval from Institutional Animal Ethics Committee, albino rats of either sex (Wt. 150-250 gms) were ...

Ipomoea stolonifera (I. stolonifera) has been used for the treatment of inflammatory diseases including rheumatism and rheumatoid arthritis in Chinese traditional medicine. However, the anti-inflammatory activity of I. stolonifera has not been elucidated. For this reason, the anti-inflammatory activity of n-butanol extract of I. stolonifera (BE-IS) was evaluated in vivo by using acute models (c...

The present study investigated the effects of the ethanolic extract (ESa), fractions, and compounds isolated from Sinningia aggregata in male Swiss mice on carrageenan-induced paw edema, neutrophil migration, mechanical hyperalgesia, formalin-induced nociception, and lipopolysaccharide-induced fever. The ESa did not alter edema, neutrophil migration, or fever at any of the doses tested. However...

BACKGROUND Vernonia amygdalina is well known as a medicinal plant in folk medicine as antidiabetic, anthelmintic, antimalarial, laxative/purgative, and expectorant among others. AIM This study was conducted to investigate the antinociceptive and anti-inflammatory effects of V. amygdalina. MATERIALS AND METHODS Methanol extract of V. amygdalina leaf (MEVA) was evaluated for antinociceptive e...

Commercial hydrolysed whey proteins (WPH) were used and residual whey protein aggregates were separated by acidification and centrifugation. Two fractions were then obtained: the supernatant (WPHSU) and the sediment (WPHSE) differing in their denatured protein amount. Turbimetric titrations of proteins and their mixtures with ι-carrageenan were carried out at different pH. Fine o/w emulsions we...

Functional neuroimaging studies have implicated the prefrontal cortex (PFCTX) in descending modulation of pain and the placebo effect. This study was performed to elucidate comprehensive PFCTX gene expression in an animal model of persistent trigeminal pain. Adult male C57BL/6J mice received facial carrageenan injection and showed sustained increase in nociceptive responses. Microarray analyses...
