چکیده
erythropoietin preparations. as measured with the Limulus lvsate test. ’ As noted by Dr. Fumarola. Limulus amebocyte Ivsate can be used to remove endotoxin from erythropoietin without loss of hormone activity.7 However. such preparations may not be suitable for tissue culture work due to the presence of residual amebocyte protein. Finally. even with removal of the endotoxin, the ratio ofactive hormone to contaminating protein in these crude preparations remains approximately

Background and Objective: Subsequent to spinal cord injury (SCI), many pathological changes may occur that could lead to inappropriate conditions for repair. The most important of such changes include the death of neurons, cyst formation, glial scar, and ineffectiveness of monocytes. Adult stem cells and monocytes may provide new strategies to treat SCI. Among various types of candidate cells, ...
متن کاملMonocyte entropy in type 2 diabetic patients
Major evidence points towards a link between inflammation and type 2 diabetes, insulin resistance and diabetic complications, where monocytes are deeply involved. Entropy (information dimension) of pericellular membrane of monocytes was evaluated in diabetic patients and in control subjects. Monocytes were collected from normal healthy volunteers (n=6) and from type 2 diabetic patients (n=10). ...
متن کاملSize distribution, electronic recognition, and counting of human blood monocytes.
During a study on the separation of human blood monocytes from lymphocytes, a method was developed to recognize and count monocytes by electronic means. Lightscattering (Cytograf, Bio/Physics), and changes in electrical resistance (Channelyzer, Coulter) were used to size mononuclear leukocytes directly in cell suspensions. Both methods revealed a size distribution profile in which two populatio...
متن کاملGanoderma Lucidum Induces the Expression of CD40/CD86 on Peripheral Blood Monocytes
Background: The major immuno-modulating effects of Ganoderma lucidum include mitogenicity and activation of immune effector cells such as T cells, macrophages and natural killer cells resulting in the production of cytokines. Objective: The purpose of this study was to evaluate the expression of CD40 and CD80 by G. lucidum-treated human peripheral blood mononuclear cells. Methods: Monocytes wer...
متن کاملStudies on the Anti-inflammatory Action of 6-mercaptopurine
The mechanism of action of 6-mercaptopurine (6-MP) on an egg albumin-induced inflammatory lesion in the skin has been studied in rabbits treated with 6-MP in a daily dosage of 18 mg/kg. Relative to control animals, significant decreases in the numbers of large lymphocytes and monocytes in the blood were observed in the 6-MP-treated animals by the 9th day of treatment, without significant decrea...
متن کاملMonocyte counting: discrepancies in results obtained with different automated instruments.
To determine the accuracy of several methods for measuring the monocyte count, the results obtained by a number of different automated cell counters were analysed. Considerable discrepancies occurred for monocyte counts obtained in normal blood among the counters. The results of a visual monocyte count on a total of 800 leucocytes were used as the reference method. The technique of measuring th...
