Blood Principal sources

Cellular cytokines (interferons, G-CSF) and immune response modifiers originally produced from human cells, most often leukocytes, have now been replaced with recombinant products with well-defined structure/function. Futuristic advances in experimental hematology portend development of human blood cells produced from the hemopoetic stem cells. Yet for the foreseeable future, homologous blood donated by healthy, altruistic voluntary blood donors remains the principal source of safe and adequate supply of blood and blood products for transfusion therapy. 

Scientific studies point out an association between saturated fat and blood lipids increase due to the presence of three principal FAs myristic, lauric and palmitic. Since PA is the principal saturated acid in the diet, it is the chief saturated component used to develop the diet equations [138 139], has meant that the cholesterol-raising property of SFA has generally been attributed to their palmitic acid content. Researches that assess your action in many body functions had been based on human and animals studies, especially, with palm oil and its fractions as principal source of PA [review 142]. 

Cysteine is a principal source of sulfur in the diet, which is necessary for the production of coenzyme A and taurine. Cysteine is also ntdized in PS, espeeially in the formation of hair and skin. It supports wound healing and stimulates white blood cell activity. The N-acetyl derivative of cysteine is N-acetyl cysteine (NAC), which is more stable and is the preferred form of cysteine for oral ingestion and infusion. NAC has been shown to protect the liver from the effects of alcohol, acetaminophm, and cancer drugs.NAC provides significant free radical protection and may be beneficial in reducing oxidative damage from exercise. ... 

Fiber components are the principal energy source for colonic bacteria with a further contribution from digestive tract mucosal polysaccharides. Rate of fermentation varies with the chemical nature of the fiber components. Short-chain fatty acids generated by bacterial action are partiaUy absorbed through the colon waU and provide a supplementary energy source to the host. Therefore, dietary fiber is partiaUy caloric. The short-chain fatty acids also promote reabsorption of sodium and water from the colon and stimulate colonic blood flow and pancreatic secretions. Butyrate has added health benefits. Butyric acid is the preferred energy source for the colonocytes and has been shown to promote normal colonic epitheUal ceU differentiation. Butyric acid may inhibit colonic polyps and tumors. The relationships of intestinal microflora to health and disease have been reviewed (10). 

Peptone was used as a source of blood group A material by Goebel, who showed that the active substance it contained was principally carbohydrate and contained D-galactose and D-glucosamine. 

Blood is one of the principal substances of the body. It circulates smoothly and constantly in the body, nourishes and supports the internal organs, and maintains the functions and structures of the body. The Heart, Liver and Spleen directly influence the generation of blood. The Heart governs the blood and promotes the blood circulation it also generates the Heart-Qi and directly supports the activities of the Heart-shen. The Liver stores the blood and regulates the volume of blood in the circulation it directly supports the activities of the Hun (soul). The Spleen is able to transform food into Qi and blood, and is considered the main source of Heart-blood and Liver-blood. The Kidney stores the essence, which can also transform into Liver-blood, so is another source of blood. 

For chemicals with half-lives of months or years—such as dioxins, polychlorinated biphenyls (PCBs), polybrominated biphenyl ethers, and first-generation halogenated insecticides—biomarkers can detect exposures months or even years after they have occurred. Such lipophilic chemicals are usually measured in blood, and the principal exposure source is usually diet. After ingestion, they are readily absorbed into the blood supply blood concentration then decreases rapidly as the blood supply equilibrates with... 

Phenylbutazone causes blood dyscrasias (SED-8, 213) (SEDA-2, 92) (7,15). The most serious adverse effect is aplastic anemia which, according to Swedish and British sources, ends fatally in almost 50% of cases (15,16,17). More than 1100 deaths are on record with the principal manufacturer (SEDA-8, Essay). 

Today the predominant if not the sole source of methylmercury is derived from the methylation of inorganic mercury in aquatic sediments and soils. Methylmercury is well absorbed from the diet and distributes within a few days to all tissues in the body. It is present in the body as water-soluble complexes mainly, if not exclusively, attached to the sulfur atom of thiol ligands, and crosses the blood—brain barrier without hindrance, entering the endothelial cells of the blood—brain barrier as a complex with L-cysteine. The principal target tissue of MeHg is the brain, and its major toxic effects are on the central nervous system. Whereas adult poisoning affects the visual cortex and the cerebellum, in neonatal infants the outcome can be much more serious, ranging in its effects from cerebral palsy to developmental retardation.
