ABSTRACT
Ten duodeni of adult ram were fixed in chilled acetone, 80% ethyl alcohol, formol- alcohol solution, alcoholic bouinssolution and neutral buffered formalin solution. The distribution of alkaline and acid phosphatases were similar in theirlocation but different in their intensity and distribution according to different fixative The distribution of alkaline phosphatasein absorptive columnar cell was more intense than in goblet cells, whereas the concentration of acid phosphatase was moreintense in goblet cells than in absorptive cells in the mucosa of sheep duodenum. The study revealed that the samples wasfixed with chilled acetone gave highest reaction for alkaline and acid phosphatases than other fixative samples. No reaction foralkaline phosphatase include the lower parts of intestinal glands, paneth cells and sub mucosal glands in different fixative,whereas, paneth cells and sub mucosal glands revealed wreaked reaction for acid phosphatase in samples fixed in 80% ethylalcohol and chilled acetone respectively in duodenum of native sheep.
