Blood And Tissues

TITLE: BLOOD & TISSUES- Staining Of Blood Films & Identification Of Leukocytes. OBJECTIVES: i.To pay heed the preparation of origin films from human blood sample. ii.To learn the techniques of defame the blood films with Giemsa filthiness and Wright territory. iii.To identify and make drawing of leukocytes that bribe in human blood sample under microscope. interpellation: Leukocytes are divided into granulocytes and agranulocytes. Granulocytes are also known as polymorphonuclear leukocytes, or polys for short. Three types of granulocyte are neutrophils, bromeosinophils, basophils. Meanwhile, there are ii types of agranulocyctes which are lymphocytes and monocytes. If we observe the smear as it is after fixing, we top on trip up really little because all cells are very transparent. The erythrocytes are slightly visible, but the leukocytes are in like manner pale, just about invisible and we will not see anything inside them. To be able to observe and recognize the unlike kinds of leukocyte, we must dirt them. For this purpose, normally Giemsa stain and Wright stain are used. Giemsa stain is a mixture of dyes, based on methylene group blue (basic dye) and eosin ( acid dye). Giemsa stain is a classical blood film stain for peripheral blood smears and bone core group specimens.

The principle of Giemsa stain is the basic dye varnished the acidic sectionalisation of the burden of the cell and the acidic dye stained the basic part of the cytoplasm of the cell. Therefore, the Giemsa stain allows clear observations to recount types of leukocytes. By patch of the cells we can observe the different types of ! egg white blood cells (leukocyctes) which are, neutrophils, eosinophils, basophils, lymphocytes and monocytes under the light microscope.
