Effect of Auricularia polytricha powder with different mesh on obese rats induced by high fat diet

In order to compare the effect of Auricularia polytricha powder with different mesh on weight lossing and reducing blood lipid,obesity rat model was made by feeding the high fat diet.The body weight and food intake of rats were observed after intragastric administration the A.polytricha powder with different size.Also,the blood lipid levels and the ratio of fat and weight were tested and calculated.The results showed that there was no significant difference in food utilization rate.The body weight of rats fed with Auricularia polytricha powder with size of 100~200mesh,200~300mesh,300~400mesh and more than 400 mesh after four weeks was significant lower than the model control group( p < 0.05 or p < 0.01). The gaining weight also had significant difference( p < 0.05 or p < 0.01).Meanwhile,the rats fed with the size of more than 400 mesh Auricularia polytricha powdr had lower fat weight,fat body ratio and density lipoprotein cholesterol( hdl- c),which were significantly lower than the model control group( p < 0.05). It was concluded that Auricularia polytricha powder with size of 100 ~ 200 mesh,200 ~ 300 mesh,300 ~400mesh and more than 400 mesh had a preventive effect on lossing weight.And Auricularia polytricha powder with size of 300 ~ 400 mesh and more than 400 mesh were more effective. More than 400 mesh Auricularia polytricha powder also had lipid- lowering effect.
