ricinoleic acid/inflammation

Observational studies indicate that topical application of ricinoleic acid (RA), the main component of castor oil, exerts remarkable analgesic and anti-inflammatory effects. Pharmacological characterization has shown similarities between the effects of RA and those of capsaicin, suggesting a

Our previous study showed that the use of ricinoleic acid as an oil phase resulted in the formation of a stable pluronic lecithin organogel (PLO gel) with better thixotropic properties and higher permeation of ketoprofen than the isopropyl palmitate PLO gel. This study aims to evaluate and compare

We have investigated the pro- and anti-inflammatory effects of ricinoleic acid (RA), the main active principle of castor oil, in an experimental model of blepharitis induced by intradermal injection of carrageenan in the guinea-pig eyelid and its possible capsaicin-like mode of action on acutely

A series of 19 heterocyclic homoprostanoids were synthesized from easily available oleic and ricinoleic acids and evaluated for their possible antioxidant, anti-inflammatory and anti-hyperlipidaemic activities. Compounds with thioxo- and oxoimidazole ring (1) and (2) have shown potent antioxidant

The aim of this study was to evaluate the safety and tissue compatibility of an injectable biodegradable poly(ester-anhydride) copolymer of ricinoleic acid (RA) and sebacic acid (SA) in rats. The absorbable biomaterial containing 70% w/w of RA and 30% w/w of SA [P(SA-RA) 3:7] was implanted in rats

The antinociceptive effect of ricinoleic acid ([R-(Z)]-12-hydroxy-9-octadecenoic acid) in comparison with capsaicin (trans-8-methyl-N-vanillyl-6-nonenamide) has been investigated in several "in vivo" tests. Acute topical application of capsaicin, but not ricinoleic acid, produced by itself an

Certain nonsteroidal anti-inflammatory drugs (NSAID) of the fenamate chemical class are known to cause diarrhea in clinical use. Paradoxically, this action is shared by prostaglandins, against whose syntheses are inhibited by NSAID. This study was done to investigate the laxative potential of 5

Polyesteranhydrides synthesized by the transesterification of ricinoleic acid and sebacic acid followed by anhydride polymerization were examined as potential controlled delivery carrier for paclitaxel. Solid and liquid polymers were used. Polymers containing 30% ricinoleic acid are solid whereas

The multifactorial pathogenesis and interrelationship of blepharitis, meibomian gland dysfunction and dry eye disease poses challenges to any therapeutic approach. Current treatments are mostly palliative, with success limited by perceived inefficacy and poor patient compliance. Castor oil, a

Targeted delivery of drug-loaded implants for regional drug therapy has become an important approach to therapy. Simple and reproducible imaging methodologies to evaluate the implant noninvasively are needed. The goal of this work was to noninvasively evaluate the visibility, shape and degradation

Cutting fluids are widely used in the metal-machining industry to lubricate and reduce heat generation when metals are cut by a metal-cutting tool. These cutting fluids have caused occupational irritant contact dermatitis (OICD), and many of the additives used in these cutting fluid mixtures are

Ricinoleic acid (RA) has potential to promote wound healing because of its analgesic and anti-inflammatory properties. This study investigates the synthesis and characterization of RA liposomes infused in a hydrogel for topical application. Lecithin liposomes containing RA were prepared and

Malaria caused by Plasmodium falciparum causes numerous cases of morbidity with about 400,000 deaths yearly owing, mainly, to inflammation leading to cerebral malaria (CM). CM conventionally is treated by repetitive administration of anti-plasmodial drugs and supportive non-specific drugs,

The complement (C) system is a potent innate immune defence system against parasites. We have recently characterised and expressed OmCI, a 16 kDa protein derived from the soft tick Ornithodoros moubata that specifically binds C5, thereby preventing C activation. The structure of recombinant OmCI
