Popis: | Lentinan, a polysaccharide [(1 → 3)-β- d -glucan], at 0.1, 1.0 and 5.0 mg/kg/day was administered i.v. to rats once daily from day 15 of pregnancy to day 21 post partum. All animals were allowed to deliver their young and selected animals of the F1 generation were retained without further treatment, to provide F2 offspring. Reactions to treatment were generally dose-related and included bruising of the tail and swelling and discolouration of the pinnae. Animals at 5.0 mg/kg/day sometimes showed swollen hind limbs and cutaneous lesions of the tail. Mean spleen weight in females was increased at all dosages, more so at 1.0 and 5.0 mg/kg/day. There was no evidence of an adverse affect on litter characteristics, including the pre-weaning development of the F1 offspring, or that treatment of the F0 parents adversely affected post-weaning development and reproductive performance of the F1 offspring. |
