[The use of pectin-containing enterosorbents in exposure to radionuclides and heavy metals].

The pectin-vitamin composition (PVC) and its complex with active carbon (AC) was investigated for use as an oral sorbent to protect radionuclide (Sr-85, Cs-137) accumulation. PVC is composed of the natural mixture of cellulose, pectin (Ca-salt), flavonoides, vitamins of the B-group, PP and C. Investigation of PVC radioprotective action was carried out on the two groups of rats (n = 30) which received 1306 Bk/animal of Sr-85 or 343 Bk/animal of Cs-137 daily. One of the group of rats received every day also 300 mg of PVC. After 30 days level of Sr-85 was less by 56.6%, level of Cs = 137 was less by 27.6% in PVC-treated than in the control group (P < 0.05). Composite sorbent consisting of PVC and AC was slightly less effective in removing of Sr and Cs.
