Background: Mammary gland tissue (left half) revealed the presence of excess proliferation of fibrous tissue with disorganization of alveolar structures and the right half showed extensive fibrous tissue proliferation of mammary gland following intramammary inoculation of 2000 c.f.u. of Staphylococcus aureus. However, oral dosing of Bauhinia variegata L. bark powder at 6 gm/kg for 7 days and 3 gm/kg for another 7 days exhibited reduction of fibrous tissue in chronic mastitis. Objective: The fibrolytic effect of one week oral dosing of Bauhinia purpurea L. bark powder was studied in chronic mastitis with induced fibrosis as Bauhinia variegate L. is rarely available in plain land. Methods: Chronic mastitis with fibrosis was induced by intramammary inoculation of coagulase positive Staphylococcus aureus in group III and IV goats. Group I and III goats were injected with a single dose of ceftriaxone at 20 mg/kg intravenously, whereas group II and IV goats were orally administered Bauhinia purpurea L. bark powder at 6 g/kg for 7 days with a single dose of ceftriaxone at 20 mg/kg intravenously. Results: The t1/2β of ceftriaxone with Bauhinia purpurea L. stem bark powder in chronic mastitis increased significantly. Ceftizoxime was detected in plasma from 1 h to 48 h post dosing (pd) in group III and from 1 h to 96 h pd in group IV, respectively. Conclusion: Bark powder of Bauhinia purpurea L. at 6g/kg orally once daily increased the bioavailability of ceftriaxone and or ceftizoxime in milk due to its fibrolytic effect which was not reported earlier. Therefore, the Bauhinia purpurea L. bark powder having fibrolytic effect has the potential to reduce development of cancer.

The aqueous extract of bark of Careya arborea Roxb., locally known as Kumbhi, was screened for hepatoprotective activity against CCl 4 -induced hepatotoxicity in rats with a view to explore its application for treatment of liver disorders in animals and human beings. The hepatotoxicity induced by administration of carbon tetrachloride (CCl 4 ) as 30 % solution prepared in liquid paraffin and administered subcutaneously 1ml/kg b.wt. at every 72 h interval till the completion of experiment. The hepatotoxicity was found to be tolerated by simultaneous oral administration of aqueous extract of C. arborea (AECA) stem bark (100, 200 mg/kg b. wt.) for two weeks, with evidence of decreased level of AST, ALT, ALP and bilirubin. In addition, severe histomorphological disruption and fatty changes produced by CCl 4 in respect of cytoarchitecture were minimized and maintained by the treatment of extract. The results were compared with standard drug silymarine. The results of this study showed that AECA could afford hepatoprotective activity against CCl 4 induced liver damage in rats due to nutraceutical nature of plant.

Abstract

The plant Boerhaavia diffusa is a herb found throughout the India. The roots of the plant have been described in various herbal natural medicine literatures to possess many medicinal properties like antiinflammatory, antibacterial, diuretic, antiurethritis, hepatoprotective, anti-convulscent, antinematodal and antifibrinolytic etc
