Abstract

This study was conducted to determine the weight changes in their bodies and some organs system of albino mice that orally administrated with silver nanoparticles (Ag-NPs). Use 20 mice were divided into two groups: the first group as a control (5 animals) and the second group administrated with 200 mg/kg BW of Ag-NPs for 5, 10, and 15 days. Each period involved 5 animals. The animals weighted before and after the end of the treatment period and dissected to collect the organs (liver, spleen, kidney, gastrointestinal tract (GIT), heart and seminal vesicle) for weighting. Results indicated to obtain significant decrease (P<0.05) in the average body weights of animals after the end of each treatment period compared to the period before treatment. The results also showed a significant decrease (P<0.05) in the average coefficient relative weight of the spleen after 5 days of treatment compared to the control group. Whereas, there was a significantly increase (P<0.05) in the average coefficient relative weight of the kidneys, GIT, lung and heart after 10 days of treatment compared with the control groups. So, it seems that Ag-NPs have a negative effect on the animals' body weights and the internal organs system. Therefore more studies are necessary to evaluate the effects of this material on the histology structure of these organs.

يهدف البحث الى دراسة واجراء التحليل المورفومتري لمروحة الطيب الواقعة الى الجنوب الشرقي من العراق اعتمادا على التفسير البصري للبيانات الفضائية للقمر الصناعي لاندسات الفضائية المحسنة وتم ربط التفسير البصري بالتفسير الرقمي الناتج بواسطة برنامج نظم المعلومات الجغرافية (ArcGIS) بعد اجراء التصحيح الجغرافي لهم.تم استخدام برنامج (ArcGIS) لرسم شبكة تصريف المروحة اعتمادا على أنموذج الأرتفاع او التضرس الرقمي (DEM 30m) المستخرج من البيانات الفضائية لتحديد شكل المروحة ومطابقتها بقنوات التصريف الخاصة بها. استخدم برنامج (ArcGIS) لحساب القياسات المورفومترية لتوضيح الخواص المساحية والحدة والتضرس للمروحة . اتضح ان لمروحة الطيب خمس مراتب لقنوات التصريف وهذا يدل على انها تتغذى من مياه الأمطار بشكل اكثر من المياه السطحية. تم تحديد منطقة التغذية للمروحة بواسطة تحليل انموذج التضرس الرقمي (DEM). دلت التحاليل على قلة الغطاء النباتي والنفاذية العالية للمنطقة والتي بالتالي تعمل على زيادة ترشيح مياه الأمطار تحت السطح. كذلك دلت النتائج على ان حوض المروحة يبتعد عن الشكل الدائري وتقريبا ممتد في شكله وبالتالي الحوض له شكل مثلث. تبين ايضا من خلال النتائج ان سطح الحوض ذو ميل كبير وله تضاريس قليلة الوعورة.

Abstract

The present work was aimed to form the baseline data of normal morphological and histological structure features of liver in migratory starling (Sturnus vulgaris). Anatomically, the starling liver bird was dark red -brown in colour and located in the cranial third of the abdominal cavity and consisted of undivided lobes (left and right). The liver right lobe was larger than the left. Histological examination revealed that the liver parenchyma was covered by a connective tissue capsule which appears to be thicker in the rim of liver lobes than other area in the liver lobe. Liver parenchyma was arranged in an unlimited hepatic lobules, which composed of polygonal hepatocytes organized as irregular, radial interconnecting cords or laminae of one or two cells thickness around a central vein and separated by blood sinusoids. In the boundary of each lobule showed a portal area which consists of a branch of hepatic artery; one or more branches of hepatic vein and one to four branches of the bile duct which lining by cuboidal cells that characterized by their empty non-staining cytoplasm. The histochemical observation by using PAS staining in the current study revealed that the glycogen granules arranged close to the central vein and in the rim of liver lobules
