Evaluation of wound healing activity of Annona squamosa and cow urine ark on contaminated wounds of dogs

The wound healing activity of Annona squamosa and cow urine ark was evaluated on contaminated wounds of dogs. The granulation tissue score and contraction of wound area were studied by Visual Analog Score card. Clinically, the granulation tissue score and contraction of wound area was similar in povidone iodine and aqueous extract ointment of Annona squamosa treated group followed by fresh leaves paste of Annona squamosa treated group. However, the granulation of tissue and contraction of wound area were very less observed in cow urine ark treated group. The mean per cent healing of different treatment groups was 47.28, 49.25, 25.75 and 36.69 per cent for povidone iodine, 10 per cent ointment of Annona squamosa, cow urine ark and fresh leaves paste of Annona squamosa respectively on day 7 of treatment. The result showed non-significant difference between group 1 and 2 which were treated with povidone iodine and 10 per cent ointment of Annona squamosa respectively. However the mean per cent healing of cow urine ark treated wounds was significantly lower than other treatment groups.
