Figure 1
Histology of granulation tissue of H. indicum. (a) Granulation tissue of Group I animal (control) showing with less collagen and more macrophages. (b) Granulation tissue of Group II (standard) animal showing significant collagenation, lesser fibroblasts and capillaries. (c) Section of granulation tissue of group III animal (pet-ether extract of H. indicum) showing with less collagenation with less monocytes, fibroblasts and capillaries. (d) Granulation tissue of Group IV (chloroform extract of H. indicum) animal showing with moderate collagen and moderate macrophages. (e) Histological section of granulation tissue of Group V animal treated with methanol extract of H. indicum showing significant increased collagenation, few macrophages and capillaries. (f) Section of granulation tissue of Group VI (aqueous extract of H. indicum) animal showing moderate collagenation with less macrophages, fibroblasts, and capillaries.
