Abstract

The present research was conducted in the Department of Anatomy and Histology, Bangladesh Agricultural University, Mymensingh from July to December 2003 with a view to study the detail histology of the spleen of indigenous dog of Bangladesh. Tissues were collected from the different parts of the spleen from the dogs killed after proper euthanasia. The adult experimental dogs were apparently healthy and disease free. The tissues were passed through different stains (Van Gieson's and Verhoeffs, Bielschowsky's Silver and Potassium Ferrocyanide stains) for detail histological study. The present study revealed that the spleen was encircled by capsule and trabeculae with the internal structures of white pulp, red pulp and sinusoids that are nearly similar as found in cattle. The capsule was composed of collagen, elastic, reticular and smooth muscle fibers. The trabeculae originated from the hilus that usually contained major vessels but was poor in smooth muscle fibers. The white pulp had a fine meshwork of reticular connective tissue containing mainly lymphocytes of various sizes. Meshworks of fine reticular fibers were observed throughout the red pulp in the present study. Sinusoids of the spleen of indigenous dog were of different shapes and sizes and widely distributed within the red pulp and had both arterial and venous communications.
