Abstract

The aim of the present investigation was to ascertain whether intermale aggression (by fighting) affects thyroid gland activity in wild rat. Following intermale aggression for three hours, thyro-follicular epithelial height was significantly decreased and colloidal content in follicular lumen increased only in the subordinate rats whereas the thyroid gland of the dominant rats was not perceptibly changed. Thus, aggression inhibits thyroid gland activity only in the subordinate rats. It is suggested that this effect may be due to psychosomatic rather than physical stress during aggression.

天生具有攻击性的野生大鼠的甲状腺对雄性间攻击的反应。
本研究的目的是确定雄性间攻击(通过争斗)是否影响野生大鼠甲状腺的活性。雄间攻击作用3小时后,只有劣势大鼠甲状腺滤泡上皮高度显著降低,滤泡腔内胶体含量显著增加,优势大鼠甲状腺无明显变化。因此,攻击性仅在从属大鼠中抑制甲状腺活动。我们认为这种影响可能是由于攻击时的身心压力而不是身体压力。
