Abstract

The concentration of protein in the cerebrum of sheep after a period of feed restriction (group 2) was lower (94.5 +/- 10.2) than in normally fed sheep of group 4 (101.4 +/- 9.4 mg/g wet weight). In the group 2 the concentration of protein in the M. longissimus dorsi and in the M. semimembranosus was also smaller. A high DNA-concentration was determined in the intestinal lymph nodes, in the spleen and in the lung. The DNA-concentration of the testes of group 2 (7.17 +/- 2.92) was higher than that of the group 4 (4.46 +/- 1.70 mg/g w. w.), also that of the renal fat tissue (0.39 +/- 0.18 resp. 0.20 +/- 0.09). The highest protein: DNA-relation in group 4 was found in the fat tissue (203.5: 1) and the lowest in the spleen (15.3: 1). A high RNA-concentration was analysed in the lymph nodes, in the spleen and in the lung. The RNA-concentration in the fat tissue of group 2 (0.34 +/- 0.13) was higher that that in group 4 (0.15 +/- 0.08 mg/g w. w.).

摘要

经过一段时间限饲的绵羊（第2组）大脑中的蛋白质浓度（94.5±10.2）低于正常饲喂的第4组绵羊（101.4±9.4毫克/克湿重）。在第2组中，背最长肌和半膜肌中的蛋白质浓度也较低。在肠淋巴结、脾脏和肺中检测到高DNA浓度。第2组睾丸的DNA浓度（7.17±2.92）高于第4组（4.46±1.70毫克/克湿重），肾脂肪组织的DNA浓度也是如此（分别为0.39±0.18和0.20±0.09）。第4组中，脂肪组织的蛋白质:DNA比值最高（203.5:1），脾脏中最低（15.3:1）。在淋巴结、脾脏和肺中分析到高RNA浓度。第2组脂肪组织中的RNA浓度（0.34±0.13）高于第4组（0.15±0.08毫克/克湿重）。
