Long-Term Animal Feeding Trial of the Refined Konjac Meal Ⅱ. Effects of the Refined Konjac Meal on the Aging of the Brain, Liver, and Cardiovascular Tissue Cells in Rats

Rats of both sexes were fed on a basal feed containing 1% refined konjac meal (RKM) for 18 months and the effects of RKM on the cell aging were observed. A comparable group fed on the basic feed was used as the control. Results obtained demonstrate that the long-term feeding of RKM to rats can delay the course of cell aging of the gliocyte, cadiomyocyte, and the endothelial cell of the large and medium arteriases, hence it is likely to delay the occurrence of arteriosclerosis and improve the functions of the brain, heart and vascular system.

魔芋精粉对大鼠脑、肝、心血管细胞老化的影响

本文用含１％魔芋精粉的饲料喂饲大鼠１８个月，观察魔芋精粉对大鼠细胞老化的影响。结果表明，长期食用魔芋精粉可延缓脑神经胶质细胞、心肌细胞和大、中动脉内膜内皮细胞的老化进程，预防动脉粥样硬化，改善心、脑和血管的功能。

魔芋精粉对大鼠钙磷代谢和骨骼的影响

本文用含１％魔芋精粉的饲料喂饲大鼠１８个月，观察魔芋精粉对钙磷代谢和骨骼的影响。结果表明，食用魔芋精粉组与对照组的血清钙磷含量、股骨重和骨钙磷含量以及骨形态计量参数（骨小梁体积、骨小梁周长、类骨质周长、类骨质表面、骨皮质厚度），两组间均无显著性差异。以上结果说明大鼠长期摄入含１％的魔芋精粉饲料，对钙磷代谢及骨骼未见不良影响。
