Alterations that could lead to the cancer development may also be related to an adverse development of offspring in experimental animals. Some functional foods, which contain the polysaccharide beta-glucan, have been described as being effective in the prevention of clastogenic damage. Based on that finding, the aim of the present study was to determine the efficacy of this sugar polymer in the mutagenic and teratogenic damage control. Two sets of females, pregnant and non-pregnant, were evaluated. The results indicated that beta-glucan was effective in preventing clastogenic damage in pregnant as well as non-pregnant females. In addition, pregnant females were more susceptible to mutagenic damage. However, teratogenic effects were not prevented effectively, although there was a trend toward a reduction in level of malformations. Despite beta-glucan did not prevent malformations, it increased fetal viability and reduced number of post-implantation losses and resorption, thereby enhancing reproductive performance in females.
可能导致癌症发展的改变也可能与实验动物后代的不良发育有关。一些功能性食品含有β-葡聚糖多糖,已被描述为有效预防致裂剂损伤。基于这一发现,本研究的目的是确定这种糖聚合物在控制诱变和致畸损伤方面的功效。评估了两组怀孕和未怀孕的雌性动物。结果表明,β-葡聚糖可有效预防怀孕和未怀孕雌性动物的致裂损伤。此外,怀孕雌性动物对诱变损伤更敏感。然而,致畸作用并没有得到有效预防,尽管畸形程度有降低的趋势。尽管β-葡聚糖不能预防畸形,但它提高了胎儿的存活率,减少了着床后损失和吸收的数量,从而提高了雌性动物的繁殖性能。
