A study was made of compensatory hypertrophy and regeneration of the kidneys in Bombina bombina. Compensatory hypertrophy was manifested only after a long period of time elapsed after the operation — 5, 5 1/2 months —and was observed in only 50% of the animals. Compensatory hypertrophy is characterized by some increase of the area of the renal corpuscles. Regeneration occurred following a single stage total excision of one kidney and 2/3 of the second, as well as following excision of 2/3 of the second kidney 2 1/2 and 3 1/2 months after unilateral nephrectomy. Regeneration follows the course of regenerative hypertrophy and is characterized by increase of the weight of the kidney of the area of the renal corpuscles (by 50%) and of all the tubular components (which are doubled in area). This process is more intense than in compensatory hypertrophy. |
