Data are means (SD) for five rats per treatment.
LA, lactalbumin based control diet, containing 10% protein; PHA, kidney bean based diet, in which 5% of the lactalbumin was replaced by bean proteins, providing 42 mg PHA/rat per day; AG, LA or PHA diets containing 6 mg aminoguanidine/day. Rats in these groups were also injected intraperitoneally with 5 mg aminoguanidine in saline every day for three days.
Significantly differences between LA or ad libitum: * p < 0.05; ** p < 0.01.
