The correlation between adrenomedullar catecholamine secretion and metabolic events was investigated in previously isolated fighting male rats. Aggressive encounters were stopped before the apparition of a dominance order. Aggression consisted of short bursts of reciprocal bites, threatening behavior, and short pauses intercalated. After 30 min of fighting, the percent of catecholamine-stained adrenomedullar cells was reduced significantly in fighters. Fighters showed a significant reduction in liver glycogen, while their blood glucose was increased. Muscle-free glucose showed no statistically significant changes compared to controls, while muscle glucose consumption increased. In the muscle of fighting rats, glycogen content was decreased. Our results demonstrated that there is an adrenomedullar activation in early stages of aggression, the changes in carbohydrate metabolism being in correlation with the catecholamine activation.
在先前单独饲养的雄性格斗大鼠中，研究了肾上腺髓质儿茶酚胺分泌与代谢事件之间的相关性。在优势顺序出现之前，攻击性遭遇就停止了。攻击行为包括短暂的相互撕咬、威胁行为以及其间穿插的短暂停顿。格斗30分钟后，格斗大鼠中儿茶酚胺染色的肾上腺髓质细胞百分比显著降低。格斗大鼠的肝糖原显著减少，而血糖升高。与对照组相比，无肌肉葡萄糖无统计学显著变化，而肌肉葡萄糖消耗增加。在格斗大鼠的肌肉中，糖原含量降低。我们的结果表明，在攻击的早期阶段存在肾上腺髓质激活，碳水化合物代谢的变化与儿茶酚胺激活相关。
