The purpose of this study was to evaluate the histological toxicity of chitosanoligosaccharide on the rat. A healthy male of Wistar rat that weighted $250{\pm}350g$ was used for experiment The experimental group was divided into five groups. Group 1 was control group which treated with general food Group 2 was $F_1$ generation which was born by mating of 0.1% (1 mg/ml) chitosanoligosaccharide was supplied by feeding ad libitum for 30 days. Group 3 was $F_2$ generation which was born by mating $F_1$ generation. Group 4 was treated with 90 days of 0.1% (1 mg/ml) chitosan oligosaccharide. Group 5 was treated with 365 days of 0.1% (1 mg/ml) chitosanoligo saccharide. All experimental groups were used to 10 rat. The results were as follow: The RER dilation was observed Group 4. However, there were no significantly changes of ultrastructures in the other groups compared to the control. It was concluded that chitosanoligosaccharide can be used for nontoxic natural material.
