Effect of treatment with Withania somnifera (WS) on SK-N-SH cell survival after 24 h with acrolein (20·0 µm) using lactate dehydrogenase (LDH) and XTT assays†

(Mean values with their standard errors of four or five separate experiments performed in triplicate at least in each group)

					Acrolein (20 µm) + WS (μg/ml)
	Control		Acrolein (20 µm)		WS-12·5		WS-25·0
Assay	Mean	sem	Mean	sem	Mean	sem	Mean	sem
LDH	100·0**	4·42	215·24	7·37	139·73**	9·90	127·21**	5·96
XTT	100·0**	2·23	48·92	9·95	80·78**	6·37	81·67**	1·05

** Mean value was significantly different from that of the acrolein group (P < 0·01).

† Results are expressed as percentage of control (taken as 100 %).
