We examined the possible genotoxicity of the recently isolated or developed anti-asthmatic and anti-inflammatory substances Apocynin (CAS 498-02-2) and Acetosyringenin (CAS 2478-38-8) using short term test systems. Apocynin is a constituent of Picrorhiza kurroa, a plant from the Himalaya region.
In this work abroagation of anti-inflammatory effect of Picrorhiza kurroa extract (PK) by beta-adrenergic blockade was confirmed, which suggests alteration in cell-surface biology by PK treatment. Blockade of protein synthesis by cycloheximide pretreatment reduced PK effect, suggesting protein
Nature of adrenergic mechanisms contributing to anti-inflammatory effect of Picrorhiza kurroa suggested from earlier studies was explored in Wistar albino rats. Water soluble fraction of alcoholic extract of rhizomes (PK) potentiated castor oil-catharsis on oral administration but direct subplanter
Relative importance of various cells involved in inflammation and in anti-inflammatory action of P. kurroa extract (PK) was investigated in albino rats. Effects of chemical depletion of macrophages and polymorphs and a functional deprivement of mast cells and platelets were examined on carrageenin
Extracts of the rhizomes of Picrorhiza scrophulariiflora Pennell (Scrophulariaceae) were investigated for their in vitro and in vivo immunomodulatory properties. Diethyl ether extracts showed potent inhibitory activity towards the classical pathway of the complement system, the respiratory burst of
Picrorhiza kurroa is an important medicinal plant in the Ayurvedic system of medicine. The root and rhizome of this plant are used for the treatment of various liver and inflammatory conditions. In the present study, we sought to investigate the anti-inflammatory activity of P. kurroa rhizome
Apocynin, a constituent of Picrorhiza kurroa, successfully inhibits NADPH oxidase and shows promise as an anti-inflammatory drug. Now, we report anti-inflammatory effects of apocynin in an experimental colitis model induced by dextran sulfate sodium as well as the effects on the mediators involved
The high demand for molecular oxygen, the enrichment of polyunsaturated fatty acids in membrane phospholipids, and the relatively low abundance of antioxidant defense enzymes are factors rendering cells in the central nervous system (CNS) particularly vulnerable to oxidative stress. Excess
Humans are exposed either deliberately or unintentionally to a variety of diverse chemicals that harm the kidney. To reduce the alarming high incidence of nephrotoxicity, some chemical as well as herbal alternatives are needed. Nimesulide belongs to a group of antiinflammatory drugs that are in
Picrorhiza kurroa, the dried rhizome of Picrorhiza kurroa Royle ex Benth, is a famous Chinese herb that has been traditionally used in China. Picroside II (PII), a glycoside derivative, is the main bioactive constituent of Picrorhiza kurroa. In the past several decades, bioactive components from
Picrorhiza kurroa has a long medicinal history as a traditional medicinal plant in China and India that is widely used in clinical treatments. It is a common treatment for liver diseases, fever, diarrhoea, indigestion, and some other diseases. Modern pharmacological studies proved that P. kurroa
The effect of the indigenous drug Picrorhiza kurrooa Benth was studied on experimental acute inflammation in rats. It was observed that Picrorhiza kurrooa at a dose of 100 mg/kg b.w. has significant (p<0.01) anti inflammatory effect with respect to control, vehicle and standard drug.
Apocynin is a major active constituent of Picrorhiza kurroa that exhibits potent anti-inflammatory activity by inhibiting superoxide-generating NADPH oxidase enzyme. To elucidate detailed pharmacokinetic profile of apocynin, high-performance liquid chromatography coupled with tandem mass
BACKGROUND
Apocynin is a constituent of the medicinal herb Picrorhiza kurroa. It is an inhibitor of nicotinamide adenine dinucleotide phosphate oxidase. This compound shows potential anti-inflammatory and antioxidant effects and has been tested as a neuroprotectant in many animal models of brain
Botanicals have been used traditionally by herbalists and indigenous healers worldwide for the prevention and treatment of liver disease. Clinical research in this century has confirmed the efficacy of several plants in the treatment of liver disease. Basic scientific research has uncovered the
