Department of Pharmacology and Toxicology, Research Centre, Hindustan Antibiotics Limited, Pimpri, India.
The effect of Indian herbs namely, Asparagus racemosus, Tinospora cordifolia, Withania somnifera and Picrorhiza kurrooa on the functions of macrophages obtained from mice treated with the carcinogen ochratoxin A (OTA) was investigated. The chemotactic activity of murine macrophages was significantly decreased by 17 weeks of treatment with OTA compared with controls. Production of interleukin-1 (IL-1) and tumor necrosis factor (TNF) was also markedly reduced. Treatment with Asparagus racemosus, Tinospora cordifolia, Withania somnifera and Picrorhiza kurrooa significantly inhibited OTA-induced suppression of chemotactic activity and production of IL-1 and TNF-alpha by macropahges. Moreover, we found that Withania somnifera treated macrophage chemotaxis and that Asparagus racemosus induced excess production of TNF-alpha when compared with controls.
