Abstract:   (15052 Views)
Introduction . Although the connective-muscular structure of capsule and trabeculae of dog spleen has been described long ago but many of the reports are actually controversial and lack exact desc ription of collagen, elastic and smooth muscle distrinuition. This study was aimed to clarify this problem. Materials and Methods. Microscopic sections were made out of 15 dog spleens and stained with the following methods: 1- H & E 2-Teanzer!Unna and 3- Teanzer/Unna Masson's Trichrome. Then Microscopic slides were studied with light microscope and computerized color analysis. Results. Dog spleen capsule has 2 layers. The external layer of the capsule is fibro -elastic, while the internal layer and the trabeculae have similar myo-elastic structures. Besides, collagen and elastic fibers are circula rty placed in external layer of the capsule, but elastic and smooth muscle fibers are directed longitudinally-cicularly in internal layer of the capsule and longitudinally in trabeculae. Conclusion . The outcomes of this study ahd similar finding with previous studies suggesting that the dog spleen has two layers, which the external layer is fibro -elastic and in addition there is continuty between capsular muscles and trabecula. finally, the results showed that both trabecula and internal alyer of capsule have a myo-elastic structure.
