Blood hemoglobin

Anemias, reductions in the number of red blood cells or of hemoglobin in the blood, can reflect impaired synthesis of hemoglobin (eg, in iron deficiency Chapter 51) or impaired production of erythrocytes (eg, in folic acid or vitamin Bjj deficiency Chapter 45). Diagnosis of anemias begins with spectroscopic measurement of blood hemoglobin levels. [Pg.47]

Mallard ducks fed up to 10,000 ppm diisopropyl methylphosphonate in feed for up to 24 weeks showed no significant effects on blood hemoglobin levels, leukocyte count, and hematocrit (Aulerich et al. 1979). Doses could not be calculated in mg/kg/day because food intake and body weights were not measured in this study. [Pg.51]

These symptoms are caused by carbon monoxide s chemical properties, specifically its tendency to bond to hemoglobin in the blood. Hemoglobin is a protein found in red blood cells that transports oxygen from the lungs to cells. It contains an iron atom located at the center of the molecule to which oxygen bonds to form the complex known as oxyhemoglobin ... [Pg.21]

In chemical terms, chlorophylls are porphyrins, such as the pigments of blood (hemoglobin) and muscles (myoglobin). The tetrapyrrole ring of chlorophylls is formed by four pyrrole residues joined together by methine groups the four nitrogen atoms are coordinated with a cen-... [Pg.834]

Primary structure is the amino / ) acid sequence, which controls the shape of the protein and the role the protein serves in the body. Primary Structure Primary structure is the most fundamental of the four structural levels because it is the protein s amino acid sequence that determines its overall shape and function. So crucial is primary structure to function that the change of only one amino acid out of several hundred can drastically alter biological properties. The disease sickle-cell anemia, for example, is caused by a genetic defect in blood hemoglobin whereby valine is substituted for glutamic add at only one position in a chain of 146 amino acids. [Pg.1042]

Several nonmetallic inorganic species may act as toxicants that affect ecosystems. Spills of salts of cyanide ion, CN, from mining operations have temporarily sterilized small streams. Nitrate ion, NO3, in contaminated well water may be reduced to nitrite ion, N02, in the stomachs of ruminant animals and infants. The nitrite converts the iron(II) in blood hemoglobin to iron(III), thus producing methemoglobin, which is useless for transporting oxygen in blood. In extreme cases, fatalities have resulted in livestock and human infants. Excessive levels of carbon dioxide, C02, in water or air can be detrimental or even fatal. [Pg.117]

A particularly useful kind of biomarker used with increasing frequency during recent years consists of adducts of xenobiotics or their metabolites to biomolecules. A particularly straightforward example of such an adduct measured for many years as evidence of exposure is carboxyhe-moglobin, COHb, produced when inhaled carbon monoxide adds to blood hemoglobin, Hb ... [Pg.128]

Hematological Effects. Low serum potassium level was observed in a 22- year-old factory worker accidentally exposed by acute inhalation to barium carbonate powder (Shankle and Keane 1988). Altered hematological parameters were observed in rats following inhalation for an intermediate exposure period to 3.6 mg barium/m as barium carbonate dust (Tarasenko et al. 1977). Reported changes included decreased blood hemoglobin, decreased thrombocyte count, decreased blood glucose, decreased albumin, increased leukocyte count, and increased blood phosphorus. [Pg.17]

Figure 3.3 Relationships among pC02, pH, and [HC03 ] for the extracellular bicar-bonate-COz buffer system. "True plasma" means that the plasma was separated from blood cells under anaerobic conditions to preserve its C02 content. The normal buffer line provides a standard reference for the relationship amongpC02, [HC03 ], and pH. Its slope depends on blood hemoglobin content.
