Iron stored in the forms of ferritin and hemosiderin Iron that is not part of hemoglobin is bound to the blood protein transferrin, which transports it to storage tissues liver, bone marrow, and spleen.

The third line and the long- term chronic defense is the proliferation of macrophages by cell reproduction in the tissue, by attracting monocytes from the blood, and by increased production of monocytes.

PHZ derivatives were used firstly as antipyretics but the toxic action on red blood cells made their use dangerous Ranvers Total and free cholesterol were determined by the method of Searcy and Bergquist Indian J Nat Prod Resour.


Tocopherol protects the red blood cell from hemolysis, boosts the immune response, reduces the risk of myocardial infarction by reducing the oxidation of low density lipoprotein as well as acting as an anti-mutagen.

Functions of Granulocytes Neutrophils seek out and kill bacteria — a process called phagocytosis. There is paucity of information on this aspect of G.

As a result the cellular and chemical responses of the red blood cell to this agent have been quite thoroughly scrutinized. In addition, more water may have entered the vegetable by osmosis as a result of its membrane permeability. When administered orally, hydrazine induced pulmonary adenomas and adenocarcinomas in mice.

Irritation of the mucous membranes may produce rhinitis, salivation, coughing, choking and dyspnoea. RBC production can be judged by counting reticulocytes in the blood and by ferrokinetics, that is, the amount and traffic of iron in the blood. There were however no histological changes on the testes. The results obtained for the vitamin assay showed the raw vegetable to be a rich source of water soluble as well as fat soluble vitamins, and this is not surprising as most of these vitamins are abundant and synthesized from afticanum tissues.

The tube was then placed in the radial grooves of the micro- haematocrit Centrifuge and spun for 5 minutes at 12, revolutions per minute rpm. Exposure to the material may result in gnetun possible risk of irreversible effects. The tocopherol contents of both the gnerum and cooked vegetables were determined using the method of Tsen as described by Petrus et al [16][17].
