Table 2. Inflammation scores obtained after administration of chitosan by intramammary injection in mice.

	Inflammation scores a
Chitosan forms	Dose administered per gland (mg)
	0.1	2.5
CHOS	0 ± 0	0.17 ± 0.29
2.6 kDa	0.17 ± 0.29	0 ± 0
4.0 kDa	0 ± 0	2.75 ± 0.35

^a Inflammation scores were given depending on the mammary gland shape. The inflammation can be: 0: none or slight, 1: moderate, 2: medium and 3: severe. The values represent the mean of three observations of three different glands (3 mice) and standard deviations.
