家兔视网膜扫描电镜断层图象观察

视网膜是视觉感受部位,由10层所构成。应用光镜及电镜观察视网膜,对其构造成超微结构已有较详细的了解。我们对家兔视网膜的断裂扫描电镜观察时,得出层次清晰,立体感强的图象,可以做为光镜和透射电镜的补充,有助于对视网膜构造的认识,现简解如下: 标本制作方法:正常家兔在乙醚麻醉下摘除眼球,剖开眼球清除玻璃体,用1%α—糜蛋白酶及生理盐水冲洗视网膜表面后,用虹膜恢复器轻轻地

2008年河北省碘缺乏病防治效果调查分析

Objective To investigate the current situation of the prevention and control of iodine deficiency disorders(IDD)in the Hebei province for 2008 to find problems and provide a basis for the prevention and control of IDD.Methods According to the history of IDD,2-3 counties were chosen each city of Hebei.A town with Serious IDD historically was selected in each county with 2-3 primary schools investigated subsequently.One hundred students aged 8-10 years old were chosen to examine their thyroid size and to collect urine samples for iodine content.Forty salt samples chosen from the above students and 50 urine samples of fertile women.18-40 years old,living near the above school were tested for iodine content.Water iodine was detected.Results A total of 92 water samples were collected in 23 towns.The water iodine ranged from 0.21 to 61.25μg/L.AU 2410 children had their thyroids checked by the palpation method and the goiter rate was 2.4%.1312 salt samples were collected.Iodized salt accounted for 92.4%(1212/1312),of which,96.4%(1169/1212)were qualified and the consuming rate of qualified iodized salt was 89.1%(1169/1312).30.4%(7/23)of counties consumed qualified iodized salt.accounting for 90%of the total.A total of 2191 urine samples of children and 1000 urine samples of fertile women were detected to be 185.2 μg/L and 201.3 μg/L,respectively.Conclusions The iodine nutrition of two groups in Hebei province is appropriate.However,if taken separately,two groups in Wuan Rre probably at the level of defective nutrition.We presume from the results that the possibility of iodine deficiency in pregnant and nursing women is existent in areas with low coverage rate of iodized salt.Surveillance should be strengthened in these areas and the measure of replenishing iodine should be taken for pregnant and nursing women when necessary.
