ABSTRACT
A total of twelve healthy adult Madras Red ewe and Boer local she-goat teats were histologically and immunohistochemically examined. In between the teat canal and teat cistern Furstenberg’s rosette was appeared as modified zone of mucosa thrown into primary and secondary folds. The mucosal folds were lined by a bilayered cuboidal epithelium. Subepithelial area of rosette was composed of numerous lymphocytes, polymorphonuclear leukocytes, macrophages and plasma cells. Mucosa below the Furstenberg’s rosette was lined by stratified squamous keratinized epithelium. Immunohistochemical staining of rosette by CD3 antibody revealed the localization of intraepithelial ‘T’ lymphocytes in the mucosal folds. ‘T’ lymphocytes were also localized in the lamina propria region
ABSTRACT
M-mode echocardiography is a non- invasive tool for the quantitative study of heart. Rajapalayam is a guard dog and Chippiparai is a sight hound breed which both originated from the southern districts of Tamil Nadu, India. Diagnosis of cardiac diseases in our indigenous breeds has been challenging due to less or no work done regarding cardiac anatomy and physiology in native breeds. Hence, this study was undertaken to establish basic reference data in these indigenous dog breeds which will help in diagnosing cardiac diseases. Various normal cardiac parameters were documented between young and adult age groups. The results indicated that a high significant difference (P<0.01) was observed in LVDd and LVDs and only a significant difference (P<0.05) in AO and RVD values between the age groups in Rajapalayam dogs,whereas, in Chippparai dogs, a significant difference was observed in CO (P<0.05) and in LVPWs, IVSd, IVSd (P<0.0) between the young and adult age groups
