The influence of exogenous thyroid hormones on glycogen-body and liver glycogen was studied in fasted and full-fed 3 wk. old dwarf and non-dwarf White Leghorn chickens. The results indicated that in contrast to normals, the glycogen-body of the dwarf was still physiologically active at age 3 wks. and they also exhibited a relatively higher liver glycogen concentration. The liver glycogen concentration was significantly higher in T3-treated, full-fed dwarf chickens when compared with other groups. The data were interpreted to suggest that the differential response observed in both dwarf and non-dwarf chickens of increasing liver glycogen levels with T3 and T4 injections indicated that the proper ratios of serum T3:T4 were probably more vital to the normal metabolic functions than changes in the individual concentrations of either T3 or T4.
研究了外源性甲状腺激素对禁食和饱食的3周龄矮小型和正常型白来航鸡糖原体和肝糖原的影响。结果表明，与正常鸡相比，3周龄矮小型鸡的糖原体仍具有生理活性，并且它们的肝糖原浓度也相对较高。与其他组相比，T3处理的饱食矮小型鸡的肝糖原浓度显著更高。这些数据表明，在矮小型和正常型鸡中观察到的注射T3和T4后肝糖原水平增加的差异反应表明，血清T3:T4的适当比例可能比T3或T4个体浓度的变化对正常代谢功能更为重要。
