11.  Indeed Galloway et al reported the highest proliferation activity in a dietary experimental group with the lowest incidence of tumours and the converse was also found.

12.  The rats exhibited a satisfactory weight gain over the four week period and there was no significant difference in body weight or health status between the three experimental groups.

13.  The diets were isocaloric and hence, the body weight gain and the daily intake of food were similar in the three experimental groups.

18.  It also significantly reduced the number of active lesions in the experimental group, compared to those in a control group.

19.  Just eight men from the experimental group survive.

20.  The control group displayed few aggressive behaviors, but children in both experimental groups displayed a lot of aggression similar to what they had observed.
