Comparison of apoptotic index between group (B) and group (C)

	Group (B)	Group (C)	p-value (Test of significance)
Apoptotic index Mean (%)±SD	43.7±8.29	24.2±5.62	0.001

Group B (the mice received intranasal instillation of LPS), group C (the mice received BMMNCs after LPS instillation).

Apoptotic index: a percent ration between the number of active caspase3–positive nuclei in alveolar septa and total number of cell nuclei in 8 fields of each BMMNC treated mice and in those received LPS only.
