Erythrocytosis An abnormal increase in the number of circulating erythrocytes as measured by the erythrocyte count symptoms upper respiratory infection buy 200ml liv 52 amex, hemoglobin treatment 911 generic 200 ml liv 52 free shipping, or hematocrit medicine 801 liv 52 200 ml discount. Erythrophagocytosis Phagocytosis of an erythrocyte by a histiocyte; the erythrocyte can be seen within the cytoplasm of the histiocyte as a pink globule or symptoms exhaustion 100 ml liv 52 mastercard, if digested, as a clear vacuole on stained bone marrow or peripheral blood smears. Erythropoiesis Formation and maturation of erythrocytes in the bone marrow; it is under the influence of the hematopoietic growth factor, erythropoietin. A myeloproliferative disorder affecting primarily the megakaryocytic element in the bone marrow. Also called primary thrombocythemia, hemorrhagic thrombocythemia, and megakaryocytic leukemia. A condition characterized by a warm autoimmune hemolytic anemia and concurrent severe thrombocytopenia. The formation and development of blood cells at a site other than the bone marrow. The term extrinsic is used because the pathway requires a factor extrinsic to blood, tissue factor. Extrinsic Xase 479 Hematology Exudate Effusion that is formed by increased vascular permeability and/or decreased lymphatic resorption. This indicates a true pathologic state in the anatomic region, usually either infection or tumor. Faggot cell A cell in which there is a large collection of Auer rods and/or phi bodies. The result falling outside the control limits or violating a Westgard rule is due to the inherent imprecision of the test method. Small amounts can be found in the peripheral blood proportional to that found in the bone marrow. The presence of fibrin degradation products is indicative of either fibrinolysis or fibrinogenolysis. The structure resulting when thrombin cleaves the A and B fibrinopeptides from the and chains of fibrinogen. A group of coagulation factors that are consumed during the formation of fibrin and therefore absent from serum. The bonds between glutamine and lysine residues are formed between terminal domains of chains and polar appendages of chains of neighboring residues. The red tinge is caused by the presence of a glycoprotein and the purple by ribosomes. The specimen handling area of a flow cytometer where cells are forced into single file and directed in front of the laser beam. Molecules that are excited by light of one wavelength and emit light of a different wavelength. During normal lymphocyte development, rearrangement of the immunoglobulin genes and the T cell receptor genes results in new gene sequences that encode the antibody and surface antigen receptor proteins necessary for immune function. In humans, the genome consists of 3 billion base pairs of dna divided among 46 chromosomes, including 22 pairs of autosomes numbered 1-22 and the two sex chromosomes. The genetic constitution of an individual, often referring to a particular gene locus. It dehydrogenates glucose-6-phosphate to form 6phosphogluconate in the hexose monophosphate shunt. This provides the erythrocyte with reducing power, protecting the cell from oxidant injury. Glutathione A tripeptide that takes up and gives off hydrogen and prevents oxidant damage to the hemoglobin molecule. Glycoprotein Ib A glycoprotein of the platelet surface that contains the receptor for von Willebrand factor and is critical for initial adhesion of platelets to collagen after an injury. Hemoglobin that has glucose irreversibly attached to the terminal amino acid of the beta chains. An embryonic hemoglobin detectable in the yolk sac for up to eight weeks gestation.

Neural retina, pigment epithelium, epithelium of iris, dilator and sphincter pupillary muscles, nervous and neuroglial elements of optic nerve Epithelium of cornea, lens Substantia propria, endothelium of cornea, sclera, choroid, stroma and vessels of iris, ciliary body, ciliary processes, ciliary muscle, sheaths of optic nerve; anterior, posterior, and vitreous chambers Summary the corneoscleral coat, together with the intraocular pressure of the fluid contents within the eye, maintains the proper shape and size of the eyeball. Light entering the eye must cross several transparent media (cornea, aqueous humor, lens, and vitreous body) before reaching receptors in the retina. There are no blood vessels in the transparent elements, which rely on diffusion of materials for their nutrition. Peripheral regions of the cornea receive nutrients from adjacent vessels in the limbus; the remainder of the cornea depends on diffusion of nutrients from the aqueous humor. The lens receives all its nutrition from the aqueous humor which is secreted continuously into the posterior chamber by the ciliary epithelium. The aqueous humor enters the anterior chamber through the pupil and diffuses posteriorly into the vitreous chamber of the eye. The aqueous humor supplies nutrients to the transparent media of the eye and is responsible for maintaining the correct intraocular pressure. Stationary refraction occurs through the transparent cornea, in contrast to variable refraction that occurs in the lens as it changes shape to focus near or far objects on the retina during eye accommodation. The lens is held in place by zonule fibers that extend from surrounding ciliary processes and focuses an inverted, real image on the retina. The convexity and thickness of the lens are controlled by the ciliary muscle acting through the ciliary processes and zonule fibers. If the ciliary muscle contracts, the ciliary body and choroid are pulled centrally and forward, releasing tension on the zonule fibers; this allows the lens to become thicker and more convex, enabling the eye to focus on near objects. When the ciliary muscle relaxes, the ciliary body slides posteriorly and peripherally, increasing the tension on the zonule fibers and making the lens thinner and less convex to focus on far objects. The iris is continuous with the ciliary body at the periphery and divides the space between the cornea and lens into anterior and posterior chambers. The chambers communicate via the pupil, an aperture in the iris through which light passes into the lens and vitreous chamber. The dilator of the pupil consists of a single layer of radially arranged myoepithelial cells along the posterior surface of the iris. The sphincter of the iris consists of smooth muscle arranged around the margin of the iris that acts as a diaphragm to modify the amount of light entering the eye and permits vision under a variety of light conditions. The rods and cones of the retina are the photoreceptors that collect visual impressions (light patterns) and translate them into nerve impulses. This action closes cation channels, hyperpolarizes the photoreceptor, and slows glutamate release at the synaptic terminal. In this way, the photoreceptor cells detects light and passes on a generated electrical potential that is transferred to dendrites of associated bipolar cells. Rods have a lower threshold to light intensity than cones and are important in dark and light discrimination and in night vision. Light absorption and generation of an electrical impulse in cones follow a sequence similar to that in rods. Cones serve for color perception and visual acuity, responding to light of relatively high intensity. The central region of the fovea centralis consists only of cones and is in direct line with the visual axis of the eye. Here the inner layers of the retina that are beyond the outer nuclear layer are displaced laterally, allowing light almost a free pathway to the photoreceptors; in this portion of the retina vision is most acute.

Pancreatic amylase breaks down starch and glycogen to disaccharides treatment with cold medical term generic liv 52 100 ml without a prescription, and pancreatic lipase cleaves fat micelles into fatty acid and glycerol symptoms after flu shot purchase liv 52 120 ml with amex. At their beginnings medications safe during pregnancy 60 ml liv 52 fast delivery, the ducts extend into the acini and are interposed between the acinar cells and the lumen medicine 8 iron stylings buy generic liv 52 200ml online. Ductal cells within the pancreatic acini are called centroacinar cells and appear as flattened, light-staining cells with few organelles. These ducts are tributaries of the interlobular ducts found in the loose connective tissue between lobules; the transition between ducts is gradual. The epithelial lining begins as simple squamous in the intercalated ducts, increases in depth to cuboidal in the intralobular ducts, and is columnar in the interlobular ducts. The cells lining the ducts stain lightly, and organelles are not prominent in their cytoplasm. Desmosomes are scattered along the lateral cell surfaces, and the apices of adjoining cells are united by tight junctions. A scanty connective tissue consisting mainly of reticular fibers supports the intercalated and intralobular ducts. The interlobular and major secretory ducts are contained within the interlobular septae and thus are surrounded by a considerable amount of fibroconnective tissue. The primary duct runs the length of the pancreas, increasing in size near the duodenum, where it runs parallel to the common bile duct, with which it often shares a common opening at the greater duodenal papilla. An accessory duct may lie proximal to the main duct and opens independently into the duodenal lumen. Two polypeptide hormones, secretin and cholecystokinin, are released from cells of the intestinal mucosa and influence exocrine pancreatic secretion. Secretin, elaborated by S cells in the mucosa of the duodenum and proximal jejunum, stimulates the ductal system of the pancreas to secrete a large volume of fluid that is rich in bicarbonate. In the intestinal lumen, this alkaline secretion neutralizes the acid chyme from the stomach and deactivates the gastric enzyme pepsin, whose optimal activity occurs at a low pH (2. It also establishes the neutral to alkaline conditions needed for the optimal activity of pancreatic enzymes. Cholecystokinin, elaborated by I cells in the duodenal and jejunal mucosa, stimulates secretory units of the pancreas to synthesize and release pancreatic (digestive) enzymes. The proteolytic enzymes are secreted as inactive precursors (zymogens) that, in part, are converted to their active forms by enterokinase, an enzyme from the intestinal mucosa. Cholecystokinin also stimulates the gallbladder to contract, thereby adding bile to aid in neutralizing the intestinal contents and providing bile acids that act as emulsifying agents in the breakdown of neutral fats. The islets are separated from the surrounding exocrine pancreas by a delicate investment of reticular fibers, and as with all endocrine glands, the islets have a rich vascular supply. In ordinary tissue sections, the islets appear to be composed of a homogeneous population of pale polygonal cells, but with special stains and in electron micrographs, several distinct cell types can be identified (Table 15-3). Alpha cells make up about 20% of the islets and generally are located at the periphery of the islet. A few profiles of granular endoplasmic reticulum are scattered about the cytoplasm, and Golgi bodies usually are found near the nucleus. Glucagon is released in response to hypoglycemia and acts on the liver to convert glycogen into glucose, stimulates hepatic gluconeogenesis from amino acids, and stimulates adipose tissue to release fatty acids that are in turn metabolized by the liver to produce keto acids. The net effect of glucagon secretion is that blood levels of glucose, free fatty acids and ketones increase. Beta cell granules contain small, dense crystals that give them a distinctive appearance. The granular endoplasmic reticulum is less extensive and the Golgi complexes are more distinctive than in alpha cells. Beta cells produce insulin, released in response to hyperglycemia, which acts on the plasmalemma of various cell types, especially liver, muscle, and fat cells, to facilitate the entry of glucose into the cell and thus lower blood glucose. Insulin also stimulates fat synthesis, inhibits lipolysis, and stimulates the movement of amino acids into cells and their assembly into proteins. Insulin acts as a fuel storage hormone and decreases blood levels of glucose, free fatty acids, and ketones. Several other types of endocrine cells are present in small numbers in the islets. Delta cells secrete the hormone somatostatin, which inhibits hormone secretion by adjacent alpha and beta endocrine cells within the pancreatic islet.

Cell size varies considerably but generally is less than that of the basophilic erythroblast medicine park oklahoma purchase 100 ml liv 52 free shipping. The polychromatophilic erythroblasts encompass several generations of cells symptoms 7dpo cheap liv 52 200 ml amex, the size reflecting the number of previous divisions that have occurred in the basophilic erythroblast osteoporosis treatment cheap liv 52 200 ml without prescription. It is sometimes convenient to divide these cells into "early" and "late" stages on the basis of their size and on the intensity of the cytoplasmic basophilia symptoms precede an illness buy generic liv 52 60ml. Acidophilic erythroblasts (acidophilic normoblast, metarubricyte) are commonly called normoblasts. Electron micrographs show a uniformly dense cytoplasm devoid of organelles except for a rare mitochondrion and widely scattered ribosomes. The nucleus is small, densely stained, and pyknotic and often is eccentrically located. Ultimately, the nucleus is extruded from the cell along with a thin film of cytoplasm. Reticulocytes are newly formed erythrocytes that contain a few ribosomes, but only in a few cells (less than 2%) are they in sufficient number to impart color to the cytoplasm. After the usual blood stains, these cells have a grayish tint instead of the clear pink of the more mature forms and hence are called polychromatophilic erythrocytes. When stained with brilliant cresyl blue, the residual ribosomal nucleoprotein appears as a web or reticulum that decreases as the cell matures and varies from a prominent network to a few granules or threads. After loss of the nucleus the red cell is held in the marrow for 2 to 3 days until fully mature. Unless there are urgent demands for new erythrocytes, the reticulocytes are not released except in very small numbers. These young red cells form a marrow reserve equal to about 2% of the number of cells in circulation. During this process the cells accumulate granules and the nucleus becomes flattened and indented, finally assuming the lobulated form seen in the mature cell. During maturation, several stages can be identified, but as in red cell development, the maturational changes form a continuum, and cells of intermediate morphology often can be found. The stages commonly identified are myeloblast, promyelocyte, myelocyte, metamyelocyte, band form, and polymorphonuclear or segmented granulocyte. An alternative nomenclature substitutes the stem granulo for myelo, and the series of stages becomes granuloblast, progranulocyte, granulocyte, metagranulocyte, band form, and polymorphonuclear granulocyte. Myeloblasts are the first recognizable precursors of granular leukocytes and represent a restricted stem cell committed to granulocyte and monocyte production. The cytoplasm is rather scant and distinctly basophilic, but much less so than in the proerythroblast, and lacks granules. Electron microscopy reveals abundant free ribosomes but relatively little granular endoplasmic reticulum; mitochondria are numerous and small. The round or oval nucleus occupies much of the cell, stains palely, and presents a somewhat vesicular appearance. The nucleus may be slightly flattened, show a small indentation, or retain the round or oval shape. Chromatin is dispersed and lightly stained, and multiple nucleoli still are present. The basophilic cytoplasm contains purplish red azurophil granules, which increase in number as the promyelocyte continues its development. Loss of Nucleus Ordinarily, the nucleus assumes an eccentric position in the cell (late normoblast) and is lost just before the cell enters a marrow sinusoid. Active expulsion of the nucleus by the normoblast has been observed in vitro and may involve some contractile protein, possibly spectrin. Enucleation of erythrocytes also has been described as the cells pass through the pores in the sinusoidal endothelium. The flexible cytoplasm is able to squeeze through the pore, but the rigid pyknotic nucleus is held back and stripped from the cell along with a small amount of cytoplasm. Azurophil granules are formed only during the promyelocyte stage and are produced at the inner (concave) face of the Golgi complex by fusion of dense-cored vacuoles.
