Abstract
  1. Food deprivation resulted in significant decreases in muscle carbohydrate, lipid and water content and increased ATP, ADP, AMP and total adenylate levels over the 21-day experimental period. 2. In the hepatopancreas phosphoarginine was significantly higher on day 21 in the starved crayfish. 3. Muscle energy charges remained within optimal (unstressed) ranges, while hepatopancreatic energy charges of food-deprived crayfish fell into suboptimal (stressed) ranges, indicating the necessity of examining organs separately to accurately ascertain metabolic changes in response to stressors.
摘要
  1. 在为期21天的实验期内,食物剥夺导致肌肉中的碳水化合物、脂质和水分含量显著下降,同时ATP、ADP、AMP和总腺苷酸水平升高。2. 在饥饿小龙虾的肝胰腺中,第21天时磷酸精氨酸显著更高。3. 肌肉能量电荷保持在最佳(无应激)范围内,而食物剥夺的小龙虾的肝胰腺能量电荷则降至次优(应激)范围,这表明有必要分别检查各个器官,以准确确定对应激源的代谢变化。
