Comparative histochemical studies of lacrimal gland in Ruminants

The present study was carried out to observe the histochemical details of the lacrimal gland in ruminants. The lacrimal gland located at the dorsolateral aspect of the eyeball which helps to nourish the cornea. In the present study a strong PAS positive reaction were seen in the secretory units of lacrimal gland in cattle, sheep and goat whereas, few secretory units showed strong PAS positive reaction and few secretory units showed weak PAS positive reaction in buffalo. Few secretory units and few secretory cells in some secretory units showed positive reaction for Alcian blue at (pH 2.5) in cattle, buffalo, sheep and goat. Intralobular and interlobular lipids were observed in buffalo, sheep and goat.
