Selenium as a chemopreventive agent in experimentally induced colon carcinogenesis

Table 1 Effect of selenium on body weights of animals subjected to 20 wk of DMH treatment

Groups	Body weight (g)
	0 d	20 wk
I normal control	135 ± 15.00	282 ± 16.43
II DMH	134 ± 16.73	210 ± 15.81d
III selenium	134 ± 15.11	284 ± 37.81
IV DMH + selenium	134 ± 20.70	246 ± 33.61ab

^bP < 0.01 and

^dP < 0.001 by one-way ANOVA followed by LSD test when values are compared with normal control group;

^aP < 0.05 by one-way ANOVA followed by LSD test when values of group IV animals are compared with group II animals. Values are expressed as mean ± SD.
