Evaluation of Punarnavadi Mandura for haematinic activity against mercuric chloride-induced anemia in albino rats.

Background: Punarnavadi Mandura, a compound Ayurvedic formulation, is one of the most commonly used medicine in the treatment of anemia (Pandu) in Ayurveda. The safety profile of this formulation is well established; however, no pharmacological study has been reported to provide the scientific basis for its use in the treatment of anemia.

Aim: To evaluate the hematinic effect of Punarnavadi Mandura against mercuric chloride-induced anemia in albino rats.

Materials and methods: The test drug (Punarnavadi Mandura) was suspended in distilled water and administered orally in a dose of 450 mg/kg for 30 days in rats. Anemia was induced by simultaneous administration of mercuric chloride (9 mg/kg) for 30 consecutive days. Body weight was noted for each animals. At the end, haematological parameters, anaemia markers like serum iron, ferritin, and total iron binding capacity (TIBC), as well as relative weight of organs and histopathology investigation, were examined.

Results: Exposure of mercuric chloride to rats for 30 days resulted in a significant decrease of body weight, an increase in the weight of the liver and kidney and a decrease in hemoglobin content. It also decreased serum ferritin to a significant extent and increased serum TIBC. Histopathology of the liver shows macro fatty changes, vacuolization, marked necrosis, and severe degenerative changes, while the kidney shows cell infiltration. All these changes were significantly attenuated by the administration of Punarnavadi Mandura.

Conclusion: The present data indicate that Punarnavadi Mandura has possessing marked cytoprotective activity, significantly attenuated the HgCl₂-induced adverse changes on red blood cell related parameters, and showing hematinic activity in albino rats.
