Gum Arabic Increases Phagocytosis of by Blood Leukocytes of Young and Old Healthy Volunteers.

Background: Gum arabic, a polysaccharide exudate from (L.) Willdenow trees, has already been used by African native people in natural medicine.

Methods: Using whole-blood samples from young (20-35 years) and older (>80 years) healthy volunteers (each group n = 10), the effect of an aqueous solution of GA on phagocytosis of was examined with a gentamicin protection assay.

Gum arabic (GA) is a traditional herbal medicine from (L.) Willdenow trees, which consist of a complex mixture of polysaccharides and glycoproteins. It is used in daily applications for several diseases and is considered to protect against bacterial infections.

Comparison Between KEDTA and Lithium Heparin as Anticoagulant to Isolate Bovine Granulocytes From Blood.

Granulocytes play a key role in the defense against invading pathogens. To study granulocyte functions, the isolation of a pure and active cell population from fresh blood is required. Anticoagulants and red blood cells (RBCs) lysis used in the isolation procedure may influence cell harvest, cell marker expression, and pre-activation of cells.
