Abstract

The removal of the thyroid gland in newborn or in young adult rats causes reduction in the number of peripheral blood lymphocytes and depression of either the humoral immune reactions against sheep and chicken red blood cells or the response of spleen cells to phytohaemagglutinin. These immunological defects are fully established in perinatally thyroidectomized rats after weaning, while in animals thyroidectomized in young-adult age they are observable 45–60 days after the operation. In both cases daily injections with thyroxine can completely restore the lymphoid system of thyroid-deprived animals. These results stress the importance of thyroid hormones for lymphocyte proliferation either during the period of ontogenetic development or in adult life.

摘要

切除新生或幼年成年大鼠的甲状腺会导致外周血淋巴细胞数量减少,以及针对绵羊和鸡红细胞的体液免疫反应或脾细胞对植物血凝素的反应受到抑制。这些免疫缺陷在围产期甲状腺切除的大鼠断奶后完全形成,而在成年期甲状腺切除的动物中,术后45 - 60天可观察到这些缺陷。在这两种情况下,每天注射甲状腺素都能完全恢复甲状腺缺失动物的淋巴系统。这些结果强调了甲状腺激素在个体发育期间或成年生活中对淋巴细胞增殖的重要性。
