[Effects of Rodiola extract on the cytotoxic activity of natural killer cells of the liver, spleen, lungs and small intestine in rats after partial hepatectomy].

In experiments on Wistar rats the cytotoxic activity of NK on the 1, 2, 10 days after partial hepatectomy (PH) and the application of Rodiola extract (RE) was studied. After 5 injections of RE the NK activity in gut increased by 112%, and after 12 ones (towards the end of experiment) by 222% in the spleen. The decreasing of this index in a first day after PH in lung, liver and gut was shown to restore in these tissues to the end of experiment. The absence of NK cytotoxicity diminishing just after PH in all the tissues was shown in operated animals, receiving RE and the decreasing of this index was found only in the lungs (by 335%).
