The recovery of the injured muscles were studied in young (aged 1 month), adult (aged 3-4 months) and old (aged 24-30 months) outbred male rats (24 animals in each group) after alloplasty of the injured area with the muscle tissue taken from the animal of the same age under the conditions of implantation of muscle tissue, non-irradiated by laser, into the area of injury of the muscle irradiated by laser (1st series) and vice versa, implantation of the muscle tissue irradiated by laser, into the area of injured non-irradiated muscle (2nd series). It is shown that in each age group in the 1st and the 2nd series, the allogeneic muscle tissue is is capable of regeneration. The regenerate mass s and the proportion of muscle tissue in them tended to be greater in the animals in the 1-series, as compared to those in the 2nd series. Alloplasty with the muscle tissue of the animal of the same age was more effective in young rats than in the old ones.
在将未受激光照射的肌肉组织植入受激光照射的肌肉损伤区域（第一组）以及反之将受激光照射的肌肉组织植入未受照射的损伤肌肉区域（第二组）的条件下，对幼年（1月龄）、成年（3 - 4月龄）和老年（24 - 30月龄）远交系雄性大鼠（每组24只动物）受伤肌肉的恢复情况进行了研究。结果表明，在第一组和第二组的每个年龄组中，同种异体肌肉组织都能够再生。与第二组相比，第一组动物的再生组织量及其肌肉组织比例往往更大。与老年大鼠相比，用同年龄动物的肌肉组织进行同种异体成形术在幼年大鼠中更有效。
