Popis: Hypophysectomy reduces mitotic activity of the frog ( Rana pipiens and Rana catesbeiana ) lens to zero within 3–4 wk after surgery. The effects are reversed by pituitary powder or bovine growth hormone. Although TSH and T 3 are mitogenic in intact organisms, they are unable to reverse the effect of hypophysectomy. The data suggest they may not be natural regulators of mitotic activity in frogs. Growth hormone is a more probable candidate.
