ABSTRACT
AIM: To evaluate antioxidant activity, DNA damage inhibition and hepatoprotecitve potential of polyherbal formulation Tritone (Livosone). METHODS: In vitro antioxidant activity of Tritone formulation was performed by using DPPH assay. Hepatoprotecitve potential of Tritone was evaluated against various hepatotoxic agents including Paracetamol (2g/kg b. wt p.o. single dose on 15th day), Galactosamine (400mg/kg b. wt. i.p. single dose on 8th day) and Alcohol (30% p.o.1ml/100g of rat for 15days). Tritone formulation at the doses of (40.5, 81 and 162mg/kg) and standard silymarin (100mg/kg) and Liv52 (270mg/kg) were administered p.o. The hepatoprotective assessment was done by estimating biochemical parameters: SGOT, SGPT, ALP and Total Bilirubin total protein and ChE levels. Additionally histopathological and DNA fragmentation study of Tritone was also performed. RESULT: Administration of hepatotoxins (paracetamol, D-GaiN and alcohol) in experimental animals showed significant biochemical, histological deterioration and DNA fragmentation. Pretreatment with Tritone (Livosone) shows significant reduction in serum SGOT, SGPT, ALP and total bilirubin levels and shows significant elevation in total protein and cholinesterase (ChE) levels compared to groups treated with hepatotoxic agents. Histopathological observations of rat liver pretreated with Tritone (Livosone) shows significant protection against hepatic damage. Inhibition of DNA fragmentation by Tritone indicates protective effect of formulation on liver at molecular level. Finally all the results were compared with standard drugs Silymarin and Liv52. CONCLUSION: Correlation of antioxidant activity, biochemical results, histopathological changes and inhibition of DNA damage after treatment with Tritone shows maximum hepatoprotective potential at dose 81mg/kg and 162mg/kg.

Stem cells are primitive self renewing undifferentiated cell that can be differentiated into various types of specialized cells like nerve cell, skin cells, muscle cells, intestinal tissue, and blood cells. Stem cells live in bone marrow where they divide to make new blood cells and produces peripheral stem cells in circulation. Under proper environment and in presence of signaling molecules stem cells begin to develop into specialized tissues and organs. These unique characteristics make them very promising entities for regeneration of damaged tissue. Day by day increase in incidence of heart diseases including left ventricular dysfunction, ischemic heart disease (IHD), congestive heart failure (CHF) are the major cause of morbidity and mortality. However infracted tissue cannot regenerate into healthy tissue. Heart transplantation is only the treatment for such patient. Due to limitation of availability of donor for organ transplantation, a focus is made for alternative and effective therapy to treat such condition. In this review we have discussed the new advances in stem cells such as use of cord stem cells and iPSC technology in cardiac repair. Future approach of CB cells was found to be used in tissue repair which is specifically observed for improvement of left ventricular function and myocardial infarction. Here we have also focused on how iPSC technology is used for regeneration of cardiomyocytes and intiating neovascularization in myocardial infarction and also for study of pathophysiology of various degenerative diseases and genetic disease in research field.
