| regeneration induced in the forelimbs by treatment with vitamin a in the froglets of rana breviceps. | young froglets rana breviceps do not possess the power to regenerate forelimbs after amputation through metacarpals. however, 5 min immersion of limb stumps in an oily solution of 150,000 iu vitamin a palmitate immediately after amputation, and once on each of the 3 subsequent days, induced definite though hypomorphic regeneration in 100% cases. | 1979 | 520457 |

| restoration of limb regeneration ability in frog tadpoles by electrical stimulation. | electrical stimulation of advanced tadpoles of rana breviceps for 24 hr with 3 microa current after hindlimb amputation through shank and ankle slightly increased the number of perfect regenerates as compared to controls. when amputation was made through thigh in tadpoles of the same stage regeneration failed in all cases of the controls but 24 hr stimulation of these tadpoles after similar operation with 3 and 10 microa currents induced fair degree of regeneration in 9 and 40% cases, respective ... | 1990 | 2253965 |
| association preference and mechanism of kin recognition in tadpoles of the toad bufo melanostictus. | in experiments with specially designed choice tanks, tadpoles of bufo melanostictus spend significantly greater amounts of time near kin than near non-kin. however, in the absence of kin members, they prefer to spend more time near non-kin rather than stay away in isolation in the opposite blank zone with no company. this implies that association of toad tadpoles with their kin is due to attraction rather than repulsion from non-kin. experiments designed to elucidate the sensory basis of kin rec ... | 2009 | 19805905 |
