Antioxidant activity of tuberosin isolated from Pueraria tuberose Linn
Antioxidant activity of Pueraria tuberose DC, (PT) Leguminosae (Fabaceae) has already been reported by us and here an active compound has been isolated and its action on expression of iNOS protein has been explored by using LPS induced changes in attached rat peritoneal macrophage cell culture. The pure compound was isolated by column chromatography and its structure was characterized by spectral studies, which was identified as tuberosin (5 hydroxy 3,4,7,3',4' pentamethoxy flavone). Its antioxidant capacity was determined and compared with alcoholic extract as EC50 value for scavenging potential towards pre-generated monocation ABTS* radical, superoxide radicals, hydroxyl radicals, metal chelation property and on lipid peroxidation. Further, rat peritoneal macrophages were isolated, cultured and the attached macrophages were exposed to lipopolysaccharide (LPS) with different concentrations of tuberosin (pretreatment for 30 min). After 17 h the released NO content, in culture supernatant, was indirectly estimated as accumulated nitrite by Griess reagent. To understand the mechanism of action, the extent of expression of inducible nitric oxide synthase genes, the iNOS protein was assessed in macrophage lysate by using its antibody on western blot analysis. Tuberosin significantly scavenged all the species of FRs, described above and it also inhibited the LPS induced release of NO and amount of iNOS protein in macrophages. All the changes were significant and concentration dependent. Thus it could be suggested that tuberosin, is one of the active principles of Pueraria tuberose, which directly scavenges various species of Free radicals (FRs) and also inhibits LPS induced inflammatory changes in macrophages

Radiation Induced Gastrointestinal Damage and Protection: Nigella Sativa Seed Extract and Thymoquinone
Ionising radiation therapy is a common treatment for different types of cancers. The side effects associated with radiation includes destruction of normal cells, especially the dividing cells. The cells in the gastrointestinal (GI) tract and bone marrow are the primary targets. The GI damage is reflected by early histological changes, functional alterations and symptoms of nausea, vomiting and diarrhea. This has been designated as the radiation syndrome. Many synthetic drugs have been used to treat GI disorders but a definite cure has not been discovered so far and these available medications also cause several side effects. The herbal extracts are being tested for long time as preventive food supplement/drug in this disease. The radio protective effects of Nigella sativa (black cumin, (Ranunculacea) is already reported but its mechanism of action is not well established. Here in this review this aspect has been explored with special reference to various in vitro and in vivo models

BHUx: A Patent Polyherbal Formulation to Prevent Atherosclerosis
Ayurvedic medicine is a time-tested system of medicine which has been in clinical use for centuries in India. Being a time-tested system, it has an edge over other existing systems of health management, especially for dealing with chronic disorders such as coronary artery disease, which is of a complex multi-etiological nature. Recently, we have shown that BHUx, a patented polyherbal formulation consisting of the aqueous fraction of five medicinal plants of the ayurvedic system, has significant anti-inflammatory properties through inhibition of cyclooxygenase-2 and lipoxygenase-15. Here we have investigated its effect on diet-induced atherosclerosis in albino rabbits. BHUx was given orally for 3 months to rabbits pre-treated with an atherogenic diet for 3 months. After 6 months, the dorsal aorta was processed for histological studies for calcium and collagen content. The results demonstrated a remarkable reduction in intimal thickening in the treated animals. In addition, there was less calcification at the intimaâmedial interface and increased intensity of collagen cap on the surface along with an increase in survival, compared with the sham control. We suggest that BHUx is a potent, multi-factorial formulation against atherosclerosis
