Research have been done on patients with diabetes (both types I and II) of the reviewers of medical clinics in the provinces of Erbil and Kirkuk, which included (31) patients of both sexes (16 male, 15 female) aged (20-70 years) to study histomorphological structure of the red blood corpuscle (RBCs) and blood count of the white blood cell (WBCs) count, It was also examined the blood picture of healthy individuals from both sexes for comparison. The results showed the presence of histopathological changes in the red blood corpuscles, like hypochromic with anisopoikilocytosis (different shape and size corpuscles), normochromic crescent shape, hypochromic microcytic cells, mild hypochromic cells anisocytosis and others. The rise significantly in the average number of white blood cells, especially neutrophils and monocytes was detected, significant differences did not appear in the lymphocytes, eosinophil and basophils compared to the number of all kinds of white blood cells in healthy individuals (the control group

Four samples of brain at age 1-7 days postnatally were obtained, fixed by 10% neutral bufferedformalin immediately after removal from the skull, for 24 hrs. Specimens from frontal and occipital lobes were taken and immersed in formalin 10% for 48 hrs. and processed histologically to obtain slides at 6 micrometer thickness and stained with hematoxylin and eosin (H&E). The present results clarify that the mean brain measurement from the frontal to occipital pole was177.0 mm, while the measurements of the frontal and occipital cortices were 2.680 & 2.903 mm respectively. The histological technique was done to obtain slides for examination under light microscope. The result indicated that the frontal and occipital region of cerebral cortex formed by six layers, molecular, external granular, external pyramidal, internal granular, internal pyramidal and multiform layers.

The acute leukemia is a group of malignant disorders of the haemopoietic cells, characteristically related with increases of number of leucocytes in the blood. The present study is aimed to evaluation the expression of immunophenic antibodies which used on blast cells to diagnosis and classification acute leukemia by flow cytometry to define their relationship with age, gender and French-American–British (FAB) subtypes, and assessment complete blood count (CBC) including white blood cells WBCs, hemoglobin HGB, and platelets PLTs, addition to define histological changes of bone marrow biopsy (BMB) of acute leukemia patients. This study included 73 patients were newly diagnosed with acute myeloid leukemia (AML), 60 of them was adults (range 15 –77 years), and the other 13 cases were children (range 1–14 years). The patients divided into three groups: 15-35, 36-55, and 56-77 years, while children patients divided into: 0-4, 5-8 and 9-14 years. The results shown that fever and paleness were the most common clinical feature among acute myeloid leukemia patients ( adults and children).
