Blood and AIDS

Liven A large, glandular organ located in the upper abdomen. The liver cleanses the blood and aids in digestion by secreting bile. [NIH]... [Pg.70]

Gan Cao and Da Zao are assistants in the formula. They are sweet, can tonify the Spleen and accelerate the transforming function of the Spleen. In addition, they directly aid Dang Gui and Bai Shao to tonify blood, and aid Gui Zhi and Xi Xin to strengthen the Yang. [Pg.127]

HIV spreads by contact with body fluids, and the common modes of infection include sexual intercourse and contaminated needles used for intravenous drug delivery. Previously, therapeutic use of infected blood and infected breast milk for the baby were also modes of transmission but both have declined due to better screening for blood and AIDS education of expectant mothers. The virus is carried in infected CD4+ T cells, macrophages or as free viruses in blood, semen, vaginal fluids and milk. [Pg.174]

Haptocorrin—A group of carrier proteins which bind with vitamin Bi2 in the blood and aid in its transport. [Pg.2684]

The major types of mature blood cells are relatively short-lived and postmitotic, meaning they are no longer dividing. These mature blood cells are responsible for the functions of the hematopoietic system and include red blood cells (erythrocytes) that carry oxygen, granulocytes and monocytes that fight infections, and platelets that help clot the blood and aid wound healing. [Pg.163]

Another dideoxypyrimidine nucleoside active against human immunodeficiency vims is 3 -azido-2/3 -dideoxyuridine [84472-85-5] (AZDU or CS-87, 64) C H N O. Since its synthesis, (167) CS-87 has been identified as a promising antiHIV agent (168) and is currentiy undergoing phase I clinical trials in patients with AIDS and AIDS-related complex. It appears to be less potent than AZT against HIV in a peripheral blood mononuclear (PBM) cell screening system and in MT-4 cell lines. This lower activity in PBM cells appears to be related to a lower affinity of CS-87 for the enzyme responsible for its initial phosphorylation (169). However, CS-87 has significantly lower toxicity on bone marrow cells than AZT (170) and penetration of the CNS as a 5 -dihydropyridine derivative. [Pg.314]

Inhalation. The threshold limit value of HCN is 4.7 ppm. This is defined as the maximum average safe exposure limit for a 15-min period by the Occupational Safety and Health Administration. Exposure to 20 ppm of HCN in air causes slight warning symptoms after several hours 50 ppm causes disturbances within an hour 100 ppm is dangerous for exposures of 30 to 60 min and 300 ppm can be rapidly fatal unless prompt, effective first aid is adininistered. There is always a small concentration of cyanide (0.02 to 0.04 mg/L) in the blood, and the body has a mechanism for continuous removal of small amounts, such as from smoking, by converting it to thiocyanate, which is discharged in the urine. [Pg.380]

Heparin inhibits the formation of fibrin clots, inhibits the conversion of fibrinogen to fibrin, and inactivates several of the factors necessary for the clotting of blood. Heparin cannot be taken orally because it is inactivated by gastric acid in the stomach therefore, it must be given by injection. Heparin has no effect on clots that have already formed and aids only in preventing the formation of new blood clots (thrombi). The LMWHs act to inhibit clotting reactions by binding to antithrombin HI, which inhibits the synthesis of factor Xa and the formation of thrombin. [Pg.424]

Obtain spirometry measurements to assess airflow limitation and aid in severity classification and treatment decisions. Measure arterial blood gases if FEV is less than 40% predicted or if the patient has clinical signs suggestive of respiratory failure or right heart failure. [Pg.242]

HIV is present in peripheral blood mononuclear cells, the major source of transmitted virus. Titers, however, are quite low, about 10,000 infectious doses per ml of blood, so that the blood is less infectious than in hepatitis B virus infections. The amount present tends to fall after seroconversion and rises again during development of AIDS-related complex and AIDS. Smaller amounts of virus are also present in semen and saliva, and probably even smaller amounts in colostrum, the human cervix, and tears. Infection is reported in CD4 positive submucosal cells in the rectum and large bowel and could be a route of entry in homosexuals. [Pg.201]

The synthesis of arginine from citrulline. The latter is produced from other amino acids in the small intestine and then released into the blood. The kidney takes up citrulline and converts it to arginine, which is then released into the blood for use by other tissues (Figure 8.18). Since arginine is a precursor for a number of important compounds, and aids wound healing, this is a significant biochemical role of the kidney. [Pg.170]

Polyvinyl chloride can be shaped into clear, soft flexible tubing and sheets with the aid of using plasticizers such as diethylhexyl phthalate (DEHP). Polyvinyl chloride resins are used for children s toys, automobile seat covers, and for catheters used for intravenous transfusion of blood and nutrients in hospitals and homes. When DEHP was suspected of leaching out of the products, and of being a carcinogen, substitutions were developed with polyvinylacetate and polyethylene. However, these substitutes are not yet totally satisfactory, as they cannot be steam sterilized, and they are not as clear and flexible as PVC. [Pg.304]

Filgrastim also shows therapeutic promise in the treatment of additional conditions characterized by depressed blood neutrophil counts. Such conditions include severe chronic neutropenia, leukaemia and AIDS. [Pg.263]
