shikonin/edema

The effect of shikonin (SK) on granulation tissue formation was biochemically evaluated and the biological effect of SK on cotton pellet induced granulation tissue formation and the induction of hind paw edema was compared with that of lambda-carrageenan (carrageenan) in rats. The dry weight of

Shikonin is one of the active components isolated from the dry root of Arnebia euchroma (Royle) Johnst (AERJ). It has been shown to have anti inflammatory activity on formaldehyde induced paw swelling in rats. Preparations of AERJ has been used clinically in curing phlebitis and vascular purpura. In

Pharmacological effects of Shikonin and Acetylshikonin, pigment components of Shikon were studied in mice, rats, guinea pigs and rabbits. The only difference between the chemical structures of the two pigments is that Acetylshikonin has the acetyl radical, while Shikonin does not. Though the

Alkannin and shikonin, two natural products from Alkanna tinctoria and Lithospermum erhythrorhizon (Boraginaceae), are used in folk medicine where they are claimed to possess, among other properties, wound healing and anti-inflammatory activity. We investigated, together with the structurally

Inflammatory damage plays an important role in cerebral ischemic pathogenesis and represents a new target for treatment of stroke. Shikonin has gained attention for its prominent anti-inflammatory property, but up to now little is known about shikonin treatment in acute ischemic stroke. The aim of

Arnebia hispidissima ethanolic extract, after chromatography, yielded a number of shikonin derivatives, which were identified as arnebin-5, arnebin-6, teracryl shikonin, arnebinone and acetyl shikonin. All these compounds were firstly reported from this plant species and evaluated to the

A pharmacological comparison between the enantiomers, shikonin (R) and alkannin (S), was made with regard to their inhibitory effects on the increased capillary permeability and thermal edema in rats, using phenylbutazone as a positive control in both models. The results of experiments have shown

OBJECTIVE Shikonin, a compound extracted from Zicao, has been demonstrated to hold anti-bacterial, anti-inflammatory, and anti-tumor activities in various diseases and it has been shown to protect human organs from injuries. However, the effect of shikonin on the recovery of spinal cord injury (SCI)

BACKGROUND Shikonin, a natural naphthoquinone pigment extracted from the root of Lithospermum erythrorhizon, has shown a variety of pharmacologic properties including anti-inflammatory effect. In the present study, we analyzed the role of shikonin in acute lung injury induced by lipopolysaccharide

The root extracts of Onosma leptanhtha were evaluated for their anti-iflammatory and cytotoxic activities. The cyclohexane extract, which appeared as the most active in both assays, has been further subjected to bioassay-directed fractionation to afford the naphthazarine derivatives:
