为了研究工频电磁场对钙、镁离子代谢的影响,作者共使用14只雄性大鼠,实验组、对照组各7只。实验组大鼠在50Hz,50kv/m电磁场下暴露5小时,然后立即处死。准确地称取组织重量(100～200 mg),在80℃烘箱内烤干恒重;然后用瓷坩锅在马弗炉内灰化(550～650℃);灰渣用3 ml 3 N HCl溶解。取1ml以0.36N HCl稀释至50ml;往其中加入氯化镧,
In order to study the effect of power frequency electromagnetic field on the metabolism of calcium and magnesium ions, a total of 14 male rats were used, and the experimental group and the control group each had 7 rats. Rats in experimental group were exposed to 50kv / m electromagnetic field for 5 hours and then sacrificed immediately. Accurately weighed tissue weight (100-200 mg), oven-dried in a constant weight at 80 ° C, then ascended in a muffle furnace (550-650 ° C) using a porcelain crucible, and the residue was washed with 3 ml of 3 N HCl Dissolved. Take 1ml diluted with 0.36N HCl to 50ml; to which was added lanthanum chloride,
