The most popular and one of the principal stains in histology is hematoxylin and eosin stain. It gives us an overview of the tissue and its structure. Hematoxylin binds with basophilic structures – for example DNA and RNA. So we can observe nuclei stained in blue or purple color. Eosin binds to acidophilic substances such as positively charged amino acid side chains. So as the result cytoplasm is pink or orange. All samples in laboratory are stained with H&E. There are several different types of hematoxylins and eosins used in histology which will give us different results.

In this video you will see, how we stain slides with different types of hematoxylins and eosins. Finally, we will compare the results.

The spleen is one of the most frequently injured intraperitoneal organs, and management of splenic injuries may require splenectomy .. The spleen is an wedge-shaped organ that lies in relation to the ninth and 11th ribs, located in the left hypochondrium and partly in the epigastrium; thus, it is situated between the fundus of the stomach and the diaphragm. The spleen is highly vascular and reddish purple; its size and weight are variable. A normal spleen is not palpable. The spleen's key function is the removal of old red blood cells "RBCs", defective circulating cells, and circulating bacteria. In addition, the spleen helps maintain normal erythrocyte morphology by processing immature erythrocytes, removing their nuclei, and changing the shape of the cellular membrane. Other functions of the spleen include the removal of nuclear remnants of RBCs, denatured hemoglobin, and iron granules ..
