Module 5 Flashcards
An RBC abnormality wherein the RBC is described as having a finger-like or quartz like crystal of dense hemoglobin protruding from the RBC membrane
Hemoglobin SC Crystal
These are RBC inclusions primarily composed of iron which appear as an irregular cluster of small, light to dark blue granules, often near the periphery of the cells when using a wrights stain smear
Appenheimer bodies
Hexagonal crystals of dense hemoglobin formed within RBC membrane
Hemoglobin C crystal
RBC inclusions primarily composed of precipitated RNA which appear as dark blue purple fine or coarse punctate granules distributed throughout cytoplasm when using a supravital stain
Basophilic stippling
During RBC destruction via extravascular hemolysis, hemoglobin from the RBC will be degraded into heme ang globin portion, it removes the iron from heme
Heme oxygenase
During extravascular catabolism of RBC, iron removed from the heme group of hemoglobin will be transported to bone marrow for recycling to be used by developing RBC by
Transferrin
During intravascular catabolism of RBC, unbound hemoglobin that were not reabsorbed in the tubular cells will
Not be excreted in the urine and converted to oxidizied methemoglobin
Intravascular catabolism of RBC, the heme group from methemoglobin will be released in the circulation and be taken up by the transport protein known as
Hemopoxin
Intravascular catabolism of RBC, an excess heme group not eliminated by LRP- CD91 will combine to — forming —- until hemopexin is available for binding
Albumin and methealbumin
In oxygen - hemoglobin dissociation curve, when there is a decreased concentration of carbon monoxide, there is also a decrease in 2-3 DPG, leading to
Increase in Oxygen Affinity
During intravascular catabolism of RBC, hemoglobin released from RBC will be transported to liver for catabolism by
Haptoglobin
During RBC destruction via extravascular hemolysis, hemoglobin from RBC will be degraded into heme and globin portion, the protoporphyrim ring from the heme portion will be open forming the
Intermediate Biliverdin
During RBC destruction via extravascular hemolysis, hemoglobin from RBC will be degraded into heme and globin portion, the intermediate biliverdin from protoporphyrin ring of the heme portion will be converted to unconjugated bilirubin by
Biliverdin Reductase
These are RBCs with a single pointed extension resembling a teardrop or pear
Dacrocyte
Unconjugated bilirubin from thr portal circulation will be transported by albumin going to the liver and be converted into conjugates bilirubin by
Uridine Diphosphate Glucoronyl Transferase
Fragmented RBCs caused by the rupture in the peripheral circulation
Schistocyte
Metabolic shunt generates 2,3 BPG/ 2,3 DPG
Rapoport Luebering Pathway
Hemoglobin iron may become oxidized to Fe by several pathologic mechanisms. What portion of the Embden - Meyerhof pathway reduces iron to fe
Methemoglobin Reductase Pathway
What hexose monophosphate shunt products participate in the detoxification of peroxides
NADPH & Reduced Glutathione
