The histoenzymic study was conducted on ileum of neonatal buffalo calves (n=15) and their age was estimated by observing their temporary and permanent dentition. Histoenzymic distribution of different enzymes was studied on ileal peyer’s patches of neonatal buffalo calves. Strong activity of AKPase was observed at the dome and capsule of the peyer’s patch lymphoid follicles at this age. However, moderate Lactic dehydrogenase (LDH) and SDH activity was observed within the ileal lymphoid follicles. A strong activity of Glucose-6-phosphate dehydrogenase enzyme was observed in the follicles at their periphery and within center of few follicles. Also a strong positive activity of diaphorases was observed in peripheral region of the follicle as fine granular reaction. The activity of enzymes has been discussed with the physiological function of the tissue..

Background: The Pati duck constitutes a major indigenous duck variety in the state of Assam. The study of the gut associated lymphoid tissue (GALT) of Pati duck of Assam is of great value in regard to normal academic and bio-medical research aspects. It is also pre-requisite for correct diagnosis and evaluating the treatment of certain diseases like duck virus enteritis, duck cholera, aflatoxicosis, botulism etc, caused by different types of pathogens, food poisoning and food allergy. Methods: The study was conducted on Pati duck of Assam in where 45 numbers of ducks were selected by irrespective of sex at different stages of development. The birds were divided into five groups depending on its age viz., 1st week, 4th week, 16th week, 24th week and 42nd weeks old. The pieces of gut having lymphoid tissue or Peyer’s patches were collected immediately after slaughter. Samples were made cryosections (-20oC) at 10µm in thickness and were temporally stored at (-22oC). The histochemical staining was done after that. Result: The acid phosphatase activity was weak in the lymphoid follicles of 1st and 4th week of age of Pati duck, while its activity was moderate in 16th, 24th and 42th week of age.The alkaline phosphatase activity was moderate reaction in the lymphoid follicles of 1st and 4th week of age of Pati duck, while its activity was intense in 16th, 24th and 42th week of age of duck. The lymphoid follicles of both Peyer’s patches and solitary lymphoid nodules were showed moderate activity for adenosine tri-phosphatase activity in 1st and 4th week old Pati duck and strong activity in 16th, 24th and 42th week of age of Pati duck, respectively. The lymphoid nodules of intestine showed strong reaction for non-specific esterase activity in all the age groups of Pati duck.

SUMMARY The activity of several enzymes has been measured in the uterine endometrium of the rabbit during oestrus and pseudopregnancy and after injecting oestradiol benzoate or progesterone 28 days after ovariectomy. The enzyme activity of the uterine fluid has been determined during oestrus and the effect of uterine ligation studied. Progesterone and the induction of pseudopregnancy stimulated succinic dehydrogenase (SDH) and glucose-6-phosphate dehydrogenase (GDH) activity and depressed amylase and lactic dehydrogenase (LDH) activity. In ovariectomized does, glutamate-oxaloacetate transaminase (GOT) activity increased after the injection of progesterone. Progesterone also stimulated endometrial phosphatase after ovariectomy but, when given after a period of oestrogen treatment, it limited the even greater response of acid and alkaline phosphatase to oestrogen; the activity then attaining the same level as when progesterone alone was given. SDH, GDH and glycerylphosphorylcholine (GPC) diesterase could not be detected in uterine fluid but amylase and alkaline phosphatase were in greater concentration than in the endometrium. GPC diesterase was, however, found to be present in uterine tissue. Ligation of the uterus did not significantly alter the enzyme activity of the endometrium.
