Notes:
Summary Partial hepatectomy was carried out on Xenopus laevis to investigate its influence on the endocrine system. In addition to other endocrine effects, a marked hypertrophy and stimulation of the interrenal gland was observed. Activated cells contain mitochondria with extended and irregularly coiled tubules embedded in a low electron dense matrix. Hepatectomy induces two phases of proliferation [3 and 35 days postoperative (p.o.)]. After 106 days p.o. giant mitochondria possessing narrow and closely packed, parallel tubules surrounded by an electron dense matrix indicate a phase of inactivation. The smooth endoplasmic reticulum and the Golgi apparatus proliferate after hepatectomy. During activation the high lipid content seen in controls is decreased significantly.
