RESULTS In these experiments the tissues remained in an apparently healthy condition for over 12 hours and frequently demonstrated spontaneous movements. All showed the ability to remove small amounts of labeled nutrients from the media (Tables I, II and III). This uptake was greatly affected by metabolic inhibition (Table IV). The inhibition was probably more complete than would be indicated by the table, for much of the slight apparent decrease in radioactivity of the medium was most likely due to the increasing self-absorption of the samples as organic materials accumulated in the medium during the experiments. 14 . lbsor[>tion of glucose-C These experiments showed little difference in the ability of the digestive glands to remove low concentrations of labeled glucose from either sea water (Fig. 1) or ra <D c 0 —• u ra 007 OO6 005 k = 0320 = hours. 01 5 6 7 8 9 10 11 12 hours Glucose in Sea Water FIGURE 1.
