Abstract:
اجريت هذه الدراسة على عشرين معدة للجاموس المحلي الخالية من الامراض والتي جمعتمن مجزرة العـــشار في البصرة. تضمنت الدراسة الشكلية قياسات متعددة للاجزاء الاربعة من المعدة كالطول والارتفاع علاوة على حساب معدل عدد الحليمات الموجودة في الكرش في السنتمتر ال | 20 Stomach of healthy stomach of local buffalo were used in present study which collected from Al. Ashar Massacre in the city of Basrah.morphological study included several measurements for all parts of Stomach like length and width in addition to calculate the average of number of papillae that present in rumen per each Square centimeter and the average of length of these papillae as well as find the diameters of openings between chambers of Stomach. While the histological part was comprise investigate the histological structure of the wall of chambers of Stomach. Histological Section were prepared from these chambers stained with hematoxylin and eosin Stain to Study the general characters of tissue, while other sections were Stain with special Stains to detect the histochemical properties of these tissues. The morphological study showed that the stomach of buffalo formed from four chambers these are rumen, reticulum , omasum and abomasum differs in their length and width. The inner lining of rumen was contained on many papillae the average of length was 800 micrometers while their average of number was 118 papilla /cm2. while the inner lining of reticulam was included several number of lamellae which arranged in form like honeycomb. Omasal lining showed crescent lamella differs in their number and length while the wall of abomasums is divided in to two regions real gastro glands origin region and the color red and has a helical folds the seconed region is the pyloric glands region, a light colored region and the container on the irregular folds. In Histological part the present study revealed that the wall of all the chamber in buffalos, stomach were histologically composed from four layers; these are tunica Mucosa , Submucosa , Muscularis and Serosa.The tunica Mucosa of rumen was characterized by of papillae that differs in their number and length according to its region in rumen while the glands were abscent in lamina properia as well as abscent of muscularis mucosa, while the wall of abomasums appeared divided histologically into 3 regions ; cardiac , Fundic and pyloric region About the histochemical part , this study demonstrated that the collagen fibers were prevalent more density in Submucosal tunica than other histological tunicas in wall of rumen ,in contrast the elastic fibers were highly constricted in muscular tunica of the rumen and mucosal larger of reticulum in comparion with other tunicas and Submucosa of the Ommasum ,the elastic fibers showed prevalenced in all layers of the cardic region of the abomasums. this study showed prevalence of keratin in the mucosa denser than other layers in the rumen , reticulum and omasum while abscent in abomasum. this study also showed prevalence of glycogen and proteins in all parts of rumen as well as prevalence of fat and alkaline phosphatase activity in the wall of all chambers of stomach.
