Natural killer cell cytotoxicity (NKCC) was reported to manifest a circadian rhythm, peaking during wakefulness in both human blood and rat spleen. Using F344 rats, we investigated whether such fluctuations (i) reflect changes in NK cell numbers or in cytotoxicity per cell; (ii) coincide in the bloo

โฆ Synopsis
Gangliosides in the plasma of Ehrlich ascites tumor-bearing mice showed changes, both quantitative and qualitative, with of pooled plasma collected on difestimation indicated a gradual increase of gangliosides up to day of growth followed by a decline leading to a level to solvent extraction and solvent partition for the preparation below the normal by day 12. Qualitative changes studied by of gangliosides (Svennerholm and Freedman, 1980). An ahthin-layer chromatography indicated appearance of new gan-qUOt Of plasma extracted with 4 VOhmeS Of ch1oroform:methgliosides in the plasma of tumor-bearing mice, which were an01 ( 1 2 , v/v) mixture for 30 min at room temperature was absent from normal plasma. One of these gangliosides a P filtered through Whatman 1 filter paper. Residue on the filter pears to be of tumor-cell origin. Gangliosides obtained from paper was washed with chloroform:methanol:water tumor-bearing plasma enhanced tumor growth when (1.33:2.67: 1.0, v/v/v) mixture. The pooled filtrate and the washings were thoroughly mixed with one-sixth volume of adoptively transferred with tumor cells into normal mice.
