Studies on the influence of repeated injections of L-thyroxine on enzyme activity and total protein level in the blood plasma of White Rock and Sussex hens have shown that: 1. The total protein level in both races decreased significantly. 2. Activity of aldolase increased in White Rock hens while in Sussex hens it increased considerably only after the last injection. 3. Activity of alanine aminotransferase did not change in White Rock hens and increased in the blood plasma of Sussex hens. 4. In both races, the activity of aspartate aminotransferase increased initially and changed after L-thyroxine injection. 5. Activity of alkaline phosphatase increased in White Rock hens, while in Sussex hens it decreased. 6. Statistically significant differences between activities of examined enzymes in both races after L-thyroxine administration were found.
对重复注射 L-甲状腺素对怀特洛克鸡和苏塞克斯鸡血浆中酶活性和总蛋白水平的影响的研究表明：1. 两个品种的总蛋白水平均显著下降。2. 醛缩酶活性在怀特洛克鸡中增加，而在苏塞克斯鸡中仅在最后一次注射后才显著增加。3. 丙氨酸氨基转移酶活性在怀特洛克鸡中没有变化，而在苏塞克斯鸡的血浆中增加。4. 在两个品种中，天冬氨酸氨基转移酶的活性最初增加，在注射 L-甲状腺素后发生变化。5. 碱性磷酸酶活性在怀特洛克鸡中增加，而在苏塞克斯鸡中则减少。6. 在给予 L-甲状腺素后，两个品种的酶活性有统计学意义的差异。
