TABLE 1.

Relative numbers (percentage of the control value) of the pulmonary L1 sarcoma colonies and cytotoxic activity of the NK cell-enriched splenocytes (NK cells) and IFN-γ- and LPS-stimulated peritoneal macrophages (Mϕ) after single WBI (Fig. 1) of mice with 0.1 or 0.2 Gy X-rays and i.p. injection with anti-asialo GM₁ antibody or CGN.

	Pulmonary colonies [% of the control value]			Cytotoxic activity of NK cells [% lysis]		Cytotoxic activity of Mϕ [% lysis]
Group	PBS	Ab	CGN	PBS	Ab	PBS	CGN
Control	100	147*	401*	7.2	0.5*	29.4	14.6*
0.1 Gy	64*	155*	352*	11.1*	0.3*	40.4*	16.3*
0.2 Gy	68*	137*	387*	11.4*	0.3*	42.1*	17.5*

The parameters were examined on the 14th (pulmonary colonies), 2nd (NK cells), and 3rd (Mϕ) days after single WBI. Control – sham-exposed mice; 0.1 Gy – mice exposed to a single WBI with 0.1 Gy X-rays; 0.2 Gy – mice exposed to a single WBI with 0.2 Gy X-rays; PBS – mice i.p. injected with phosphate buffered saline; Ab – mice i.p. injected with anti-asialo GM₁ antibody; CGN – mice i.p. injected with CGN.

^*indicates statistically significant (p<0.05) difference from the control/PBS value.
