A review of the effects of magnetic field on main blood cells : in vivo and in vitro experiments

الملخص EN

Background: Magnetic field has being used in diagnostics for decades such as MRI.

Sources of magnetic field were found in electronic devices and may emit extremely low intensity of magnetic field.

Beside the daily use of electronic devices, there are some concerns regarding to side effects of magnetic field produces on living cells.

Main Blood cells parameters were considered, and Red blood cells have targeted as the main and most affected by magnetic field.

Concerns to blood, any abnormality in shape, aggregation, count may cause inflammations or chronic diseases such as anemia.

Objective: In this review, we evaluated the previous works carried out to investigate the effect of static and time varying magnetic fields on rheological properties (blood parameters, viscosity and DNA strand break) of blood between periods from 1980-2019.

We provided up-to-date state of research articles and the latest progress.

Different intensities of magnetic fields (week, moderate and strong) were looked at.

Result: Seventy two published research articles were reviewed.

This shortened to thirty eight articles in respect to our goal.

The chosen articles studied the biological effect of magnetic field on human and animal in vivo and in vitro experiments.

A few theoretical studies were pointed to.

Inconsistent results were compared.

Conclusion: Magnetic fields can be static or time varying as frequency is not zero.

Blood counts responded to external magnetic field with altering in counts, aggregations, change in viscosity and DNA strand break.

RBCs aggregation increased as blood is affected by magnetic field.

Whole blood viscosity enhanced the aggregation of red blood cells.

Raise in aggregation changed the time flow of blood in microcirculations.
