Abstract

This study were performed to investigate the effect of magnetic field exposure on semen characteristic and the weights of body, reproductive organs and liver, kidney and spleen in mice. In magnetic field exposure for 15 days, sperm concentrations and viability were significantly lower in magnetic field(15.7$\times$10$^{6}$ $m\ell$, 29.3%) than that in control group(25.1$\times$10$^{6}$ $m\ell$, 34.4%)(P<0.05). The proportion of sperm abnormality were significantly increased in magnetic field exposure groups for 15 days than that in control group(P<0.05). The exposure of magnetic field in mice didn't affect the body and reproductive organ weight such as testis, epididymis, vasicular gland and coagulatin gland. The weight in liver and kidney were not affect in magnetic field exposure groups. However, the spleen weight were significantly higher(P<0.05) in group exposed with than without magnetic field. This studies indicate the short or long term magnetic field exposure in mice were noxious effects on the sperm characteristics and spleen weight, but didn't affect body, reproductive organs, and liver and kidney weight.

웅성 생쥐에 자기장을 15일 동안 1일 5시간씩 60G의 강도로 노출시킨 결과, 정자농도는 대조구와 자기장 15일 처리구가 각각 25.1$\pm$6.5$\times$$10^{6}$$m\ell$와 15.7$\pm$5.3$\times$$10^{6}$$m\ell$로서 처리구가 대조구에 비하여 유의적으로 낮게 나타났다(P<0.05). 생존율은 대조구와 자기장 15일 처리구가 각각 34.4%와 29.3%로서 처리구가 대조구에 비하여 낮게 나타났지만 유의적인 차이는 인정되지 않았다(P〉0.05). 기형율은 대조구와 자기장 15일 처리구가 각각 11.7%와 18.0%로서 처리구가 대조구에 비하여 유의적으로 높은 성적을 나타냈다(P〉0.05). 체중과 번식기관 무게는 대조구와 자기장 처리구간에 차이가 인정되지 않았다. 장기무게중 간, 신장은 대조구와 자기장 처리구간에 차이가 인정되지 않았으나, 비장은 대조구와 자기장 15일 처 리구가 각각 0.116g과 0.227g으로서 처리구가 대조구에 비하여 유의적으로 높게 나타났다(P<0.05).
