不同剂量中波紫外线照射对鹌鹑内脏器官重量的影响

将10日龄鹌鹑300只(公、母各半)随机分成5组,每组60只(公、母各30只),以功率为15 W的中波紫外灯为紫外线光源,以每天连续照射1 h、2 h、4 h和6 h(紫外线照射剂量分别为1.4μW.h/cm2、2.8μW.h/cm2、5.6μW.h/cm2和8.4μW.h/cm2)的鹌鹑为试验组,未接受紫外线照射的鹌鹑为对照组,试验期为4周。系统比较了不同紫外线照射剂量下鹌鹑心脏、肝脏、脾脏、肺脏、肾脏、肌胃和腺胃等各内脏器官的重量。结果表明:每天照射1 h的中波紫外线(照射剂量为1.4μW.h/cm2)可显著增加心脏和肝脏的重量。

Effect of Different Doses of Ultraviolet B Radiation on Weights of Partial Visceras

300 ten-day aged quails（half of male and female） were randomly divided into 5 groups,in which 4 experiment groups and 1 control group,each group included 60 birds（each sex was 30）.And the experiment birds received treatment with different irradiation doses（time） of ultraviolet.The ultraviolet radiation sources were from 15 W ultraviolet B radiation（UV-B） lights.4 experiment groups were continuously irradiated for 1hour（1.4 μW·h/cm2）,2 hours（2.8 μW·h/cm2）,4 hours（5.6 μW·h/cm2） and 6 hours（8.4 μW·h/cm2） each day,respectively.The control group was not irradiated by ultraviolet radiation.The trial kept 4 weeks.The weights of partial visceras of different groups were compared.The results showed that the quails under 1 hour of UV-B irradiation（1.4 μW·h/cm2） per day were detected the largest weight of heart and liver.
