Abstract

<span style="font-size: 14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">With a view to determine ectopic limb developing capacity along with normal hind limb regeneration in response to vitamin A palmitate in well-differentiated hind limb stage tadpoles of <i><span style="font-size:14.5pt;mso-bidi-font-size: 8.5pt;font-family:" times="" new="" roman","serif""="">P. maculatus, </span></i><span style="font-size:14.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">higher doses of vitamin A (30 IU/ml

<span style="font-size:14.0pt;mso-bidi-font-size:8.0pt;line-height:115%; font-family:" times="" new="" roman","serif";mso-fareast-font-family:"times="" roman";="" mso-ansi-language:en-us;mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">and 20 IU/ml) were administered for a longer period ( 120 hr) to the tadpoles following tail amputation through middle and hind limb amputation through middle of thigh. Simultaneous development of ectopic pelvic tone was observed along with hind limbs from the cut end of tail and duplication of regenerated hind limbs in the same tadpole for the first time. Besides, development of double ectopic pelvic girdle was also reported in one case. Results also indicate that induction of pelvic zone and duplication of regenerated limbs are concentration dependent. </span></span></span>
