Effect of Pseudostellaria Polysaccharides on SIgA,IL-2 and IL-6 Contents of Intestinal Mucosal Injured Mice Caused by Cyclophosphamide

Effects of Pseudostellaria polysaccharides on the contents of intestinal mucosal SIgA, IL-2 and IL-6 in mice were reported in this paper.36 Kunming male mice with 18 to 22 g were randomly divided into six groups, blank control group, Pseudostellaria polysaccharides control group, cyclophosphamide (CY) model group, and Pseudostellaria polysaccharides low, middle, high dose groups.Each mouse in Pseudostellaria polysaccharides control group and Pseudostellaria polysaccharides low, middle, high dose groups was respectively treated with polysaccharides at the dose of 400, 100, 200 and 400 mg/kg body weight by intragastrical treatment for 19 continuous days, CY was given to each mouse in CY model group and Pseudostellaria polysaccharides low, middle, high dose groups by intraperitoneal injection with 100 mg/kg body weight in the 20th day, duodenum and ileum samples were collected from mice after 24 h, and SIgA, IL-2 and IL-6 contents were determined.The results showed that SIgA contents in duodenum were significantly increased (P<0.05) in Pseudostellaria polysaccharides middle and high dose groups compared to CY model group, SIgA contents in ileum were extremely significantly increased (P<0.01) in Pseudostellaria polysaccharides high dose group compared to CY model group.IL-2 contents in duodenum and ileum were significantly increased (P<0.05), IL-6 contents in duodenum were extremely significantly increased (P<0.01), IL-6 contents in ileum were significantly increased (P<0.05) in Pseudostellaria polysaccharides high dose group compared to CY model group.It was concluded that Pseudostellaria polysaccharide could antagonize intestinal mucosal injury caused by CY.
