ABSTRACT : The investigations on saliva and salivary glands have become focal point of a high number of studies,
which came about in an impressive advancement in the knowledge about the salivary gland. There are just a few studies
that designate the comparative histological investigation of the major salivary glands in domestic rabbit. The first study
that estimation the mucous acini between submandibular and sublingual gland. Thirty domestic rabbits were used for
this study. Paraffin sections from the three major salivary glands were stained with H & E, Masson trichrome and EGF
stain. Significantly difference (P£ 0.05) in the size and weight of the glands were observed. The length of the mean
execratory duct was significantly different between the glands (P£ 0.05). The parotid gland were the longest. The
histological results showed significant changes among the studied gland at (P ³ 0.05) in thickness of inter-lobar connective
tissue. The parotid gland possesses widest inter-lobar connective tissue followed by the sublingual gland then the
submandibular gland. Moreover, significantly difference (P£ 0.05) in the number of the intercalated ducts was found in
the lobules of the submandibular gland followed by sublingual gland then the parotid gland with less number. In addition
to that there was Significant difference (P£ 0.05) in the number of the striated ducts, with the high number found in the
submandibular gland followed by sublingual gland and the parotid gland with fewest number. Significantly different
(P£ 0.05) the number of the serous acini the high number that found in the parotid gland next the serous tubules in
submandibular gland finally the serous Demilunein the sublingual gland. Significantly different (P£ 0.05) the number of
the mucous acini in submandibular gland higher than sublingual gland. The serous acini in parotid gland are not
production of the EGF because are weakly staining by epidermal growth factor stain also ductal system. The mucous
acini in submandibular gland are production of the EGF yet, strongly positive with epidermal growth factor stain that
indicated to screted EGF. While the serous tubules, intercalated and sitrated duct are not secreted EGF. The mucous
acini in sublingual gland are positive staining by epidermal growth factor stain indicated partialy secretion of EGF. The
submandibular gland are production of the epidermal growth factor, which indected by use immunocytochemistry
technetion, however, the sublingual gland partially produced its, but neverless produced by parotid gland. The comparative
in numder and diamstter of ducts and thickest of connective tissue as well as number of acini and estimation of EGF in
each three major salivary gland.
