Fig. 5From: Carboxymethyl chitosan reduces inflammation and promotes osteogenesis in a rabbit knee replacement modelHaematoxylin and eosin staining of the synovial membrane of the knee joint (100x, bar = 100 μm; 200x, bar = 50 μm). Black arrows indicate inflammatory cells. a A large amount of inflammatory cells infiltration was observed in the control group(n = 10). b A small amount of Inflammatory cells infiltration was observed in the chitosan group(n = 10)Back to article page
