Background & Aim: Marshmallow (Althaea officinalis) is one of the most popular medicinal plants used in traditional medicine with antibacterial and antioxidant properties. This study was conducted to evaluate the effects of marshmallow extract (Althaea officinalis L.) administration on blood cells and biochemical parameters of carp liver. Experimental: 150 carp (weighing 37.6...

The binding of phosphofructokinase and aldolase to the membrane of the intact human erythrocyte was assessed by the rapid hemolysis/filtration method of Kliman and Steck (Kliman, H. J., and Steck, T. L. (1980) J. Biol. Chem. 255, 6314-6321). We found that about 50% of the phosphofructokinase was membrane-bound in fresh red cells prior to hemolysis. Binding was not significantly altered by deoxy...

background: the development of anti-red blood cell alloantibodies remains a major problem in transfusion of blood in thalassemia major patients. also, autoantibodies can result in clinical hemolysis and difficulty in cross-matching blood. we studied the frequency of red blood cell alloimmunization and autoimmunization among thalassemia patients who received regular transfusions in ilam province...

Several agents which cause injury to erythrocytes are also capable of releasing hydrolytic enzymes from lysosomes. The red cell membrane can be disrupted in vitro by exposure to saponin or detergents (1), lecithinase (2), excess vitamin A (3), ultraviolet irradiation (4), or repeated freezing and thawing. These agents and procedures are known to release degradative enzymes, e.g. cathepsins, aci...

There are evidences showing that adverse impacts of aluminum (Al) on plants growth and development are associated with its effect on plasma membrane and cell wall. Influence of Al on peroxidation of membrane lipids, wall-bound phenolics, lignin, soluble phenolics and the activity of certain enzymes involved in metabolism of phenols, i.e., phenylalanine ammonia lyase (PAL) and polyphenol oxidase...

Introduction: Introduction: Molecular components within the microenvironment act upon cell growth, survival/apoptosis, and proliferation. Immune system cells respond to molecules produced by the tumor and released in the surrounding microenvironment, such as cytokines, chemokines, and growth factors. This study aimed to identify the effects of tumor environment on monocyte-macrophage cell linea...

Cellulase production by a Cellulomonas sp., isolated in 1985 from forest humus soil along the border of the Caspian Sea in Iran, was investigated. This strain secreted endo-and exo-cellulases in the culture medium, but some of the enzymes produced remained cell membrane bound. Cell bound enzymes were released by various treatments. The highest amount of endo-glucanase (up to 95%) and exo-gl...
