Radioprotective effects of honeybee venom (Apis mellifera) against 915-MHz microwave radiation-induced DNA damage in wistar rat lymphocytes: in vitro study. med./bio.

Published in: Int J Toxicol 2009; 28 (2): 88-98

Aim of study (acc. to author)

To study the radioprotective effect of bee venom against DNA damage induced by 915 MHz microwave irradiation in rat lymphocytes.

Background/further details

Honeybee venom is a complex mixture of different active components including peptides, enzymes and amines which have a variety of pharmaceutical properties. Bee venom is used in traditional medicine to treat a variety of diseases (e.g. arthritis, rheumatism, back pain) and it has been reported that it possess anti-mutagenic, pro-inflammatory, anti-inflammatory, anti-nociceptive and anti-cancer effects. Additionally it has been reported to possess a radioprotective capacity against gamma radiation.
Whole blood lymphocytes of Wistar rats are treated with 1 µg/ml bee venom four hours prior to and immediately before irradiation.

Main outcome of study (acc. to author)

The standard comet assay revealed that microwave exposure increased the DNA damage in rat lymphocytes.
The Fpg-modified comet assay (as marker for oxidative stress induced DNA damage) revealed statistical differences compared to controls, suggesting that oxidative stress is a possible mechanism of DNA damage induction.
The data showed that bee venom has a radioprotective effect against basal and oxidative DNA damage. Bee venom alone (at a concentration of 1 µg/ml) did not have any impact on genotoxicity and did not produce oxidative damage in rat lymphocytes.
