| The activity of important glycolytic enzymes (hexokinase, phosphofructokinase, aldolase, phosphohexoseisomerase, pyruvate kinase and lactate dehydrogenase) and glutaminolytic enzymes (phosphate-dependent glutaminase) was determined in the thymus and mesenteric lymph nodes of Wistar rats submitted to protein malnutrition (6% protein in the diet rather than 20%) from conception to 12 weeks after birth. The wet weight (g) of the thymus and mesenteric lymph nodes decreased due to protein malnutrition by 87% (from 0.30 ± 0.05 to 0.04 ± 0.01) and 75% (0.40 ± 0.04 to 0.10 ± 0.02), respectively. The protein content was reduced only in the thymus from 102.3 ± 4.4 (control rats) to 72.6 ± 6.6 (malnourished rats). The glycolytic enzymes were not affected by protein... |
