The spleen of adult male Philippine carabao (Bubalus bubalis<br />
L.) was examined histologically using the H & E stain.<br />
The carabao had a storage type of spleen characterized by<br />
presence of numerous trabeculae and minimal amount of<br />
white pulp in the parenchyma. It was enclosed by a thick<br />
capsule consisting of two distinct layers: a thick outer<br />
dense white fibrous connective tissue layer (DWFCT) and<br />
an inner smooth muscle layer. The white pulp was made<br />
up of the lymphatic module and peripheral sheath that<br />
surrounded the nodular or central arteriole. The red pulp or<br />
splenic cord consisted of lymphocytes, phagocyte cells<br />
and erythrocytes separated by sinuses.<br />

GROSS AND MICROSCOPIC ANATOMY OF <strong>THE</strong><br />

The lung of the Philippine carabao was grossly and<br />
microscopically examined. Grossly, the left lung was<br />
smaller and had 2 lobes, cranial and caudal lobes. The<br />
cranial lobe was further divided into cranial and caudal<br />

parts by a U or V shaped notch. The right lung had 4 lobes<br />
namely: cranial, middle, caudal and accessory lobes.<br />
Microscopically, the lung was enclosed by a capsule<br />
composed of 3 layers; mesothelium, elastic, and subserosal<br />
layers. The lung parenchyma presented structures typical<br />
of the lung of most domestic mammalian species. The wall<br />
of the bronchus consisted of 4 layers; 1) tunica mucosa<br />
which is made up of pseudostratified columnar ciliated<br />
lining epithelium with goblet cells, lamina propria containing<br />
loose connective tissue and lymphatic tissue, and a lamina<br />
muscularis mucosae of circulatory arranged smooth muscle<br />
fibers; 2) tunica submucosa made up of loose connective<br />
tissue, solitary lymphatic nodules and mixed but<br />
predominantly mucous glands; 3) tunica muscularis<br />
contained hyaline cartilage; and 4) tunica adventitia<br />
composed of loose connective tissue. The wall of the<br />
bronchiole, except that of the respiratory bronchiole, had 2<br />
layers: 1) tunica mucosa made up of simple columnar or<br />
cuboidal ephithelium, a lamina propria with thin loose<br />
connective tissue and lamina muscularis mucosae with<br />
thin circularly arranged smooth muscles; and 2) tunica<br />
submucosa with thin layer of loose connective tissue.<br />
Respiratory bronchioles were not frequently observed.<br />
The wall of the bronchial part consisted of 1 layer; tunica<br />
mucosa composed of simple cuboidal epithelium, lamina<br />
propria with very thin loose connective and lamina<br />
muscularis mucosae with thin smooth fiber. The alveolar<br />
part was lined by simple squamous epithelium. The alveolar<br />
duct, alveolar sac and alveoli were typical of other<br />
mammalian species.<br />

ULTRASTRUCTURAL OBSERVATIONS OF <strong>THE</strong><br />
CECAL MUCOSA OF <strong>THE</strong> <strong>PHILIPPINE</strong> CARABAO<br />
(Bubalus bubalis) *<br />

The cecal mucosa of the Philippine carabao (Bubalus<br />
bubalis) was studied using transmission electron<br />
microscope. The cells lining it generally resemble those<br />
previously described in other species. The surface<br />
epithelium was lined primarily by columnar absorptive<br />
cells and a few goblet cells. The glandular epithelium was<br />
lined by goblet cells, enteroendocrine cells and
