Chronic toxicity studies of Tuttha bhasma (CuSO4.5H2O) in Wistar Albino Rats
Keywords:Sub-acute toxicity, Tuttha bhasma, Atherosclerosis, Histopathology, Cell infiltration, Anemia
Tuttha Bhasma (TB) is an important metal based drug used in Ayurveda. It has widespread therapeutic uses in the treatment of metabolic disorders. Despite of its therapeutic utility there is a lack of data related to its safety. Hence the present study was undertaken to evaluate chronic toxicity of TB in Wistar albino rats. Chronic toxicity study was conducted as per AYUSH guidelines 170 and the parameters such as ponderal changes; biochemical, hematological and histopathological examinations were recorded. Based on the overall toxicity profile significant changes in the serum SGPT was noted in therapeutic and higher dose levels. We could see the serum cholesterol, SGOT, SGPT and albumin levels were significantly elevated at lower dose compared to the control group. Histopathology of kidney showed cell infiltration and sections from liver showed mild to moderate fatty changes at higher dose levels. Histopathology of jejunum revealed there was mild to moderate epithelial erosion and shortening of epithelial layer. However overall toxicity study parameters showed the test drug TB is well tolerated and no dose dependent toxicity symptoms were observed. Based on the findings we could conclude that Tuttha bhasma is much safer to use at therapeutic dose level. However, at higher dose levels there are chances of organ toxicity.
