چکیده

The purpose of this work was to study the isolation and a light microscopy technique for cultured lymphocytes. Blood samples were obtained by venipuncture with an anticoagulant added and centrifuged in a Percoll density gradient to separate the leukocytes. Lymphocytes were placed in 25 cm tissue culture flasks at 37°C. After culturing, they were fixed and stained with the methods used for blood smears. Results showed that not all fixing solutions and stains were an equally good choice for cultured lymphocytes.

Effects of 35 Hz, 2 mT Magnetic Field on Peripheral Blood Lymphocytes of Human In Vitro and Rat In Vivo

In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...

Inhibition of IL-13 by Antisense Oligonucleotide Changes Immunoglobulin Isotype Profile in Cultured B-Lymphocytes

The link between IL-13 and bronchial hyper-responsiveness has brought this cytokine as a potential therapeutic target for asthma and allergic diseases. At the present study, we address the role of B cell derived IL-13 in the IgE and other immunoglobulin development. Antisense oligo for human IL-13 m-RNA was used to study IgE down regulation. Human B-lymphocytes were purified by positive selecti...

Modulation of in vitro proliferation and cytokine secretion of human lymphocytes by Mentha longifolia extracts

Objective: Mentha longifolia L. Hudson has been used in folk medicine for various purposes especially for its anti-inflammatory effects. Lymphocytes play a central role in development of inflammation. In the present study, we investigated the immunomodulatory effects of different extracts of M. longifolia on human peripheral blood lymphocytes (PBLs), as main players in development of inflammati...

Procedure for Embedding in Situ Selected Cells Cultured in Vitro

Ultrastructure studies of cells in vitro are greatly facilitated when the procedures used permit combined light and electron microscopy of selected cells or cellular components. The methods currently available for such studies are designed primarily for pre-selection of cells and are not suitable for high resolution light microscope observation. Such techniques are further limited because they ...

In vitro radioprotective effects of histamine H2 receptor antagonist against gamma-rays induced chromosomal aberrations in human lymphocytes.

Background: Radioprotective capability of histamine H2 receptor antagonists have been shown in several in vivo studies mainly using animal models. However, to verify the effectiveness of these agents in clinical applications, studies should be performed on human cells. In the present study radioprotective properties of these agents was examined in vitro on human lymphocytes using metaphase anal...
