  慢性硒中毒
     1. Both the two dose could cause the rabbits chronic selenosis, growth inhibition, loss of body weight. With the number of Se intake increasing, the concentration of blood selenium in experimental groups was higher than those of control rabbits (p<0.05,p<0.01), Selenium content of fetal hepar、placenta and testes was also higher than those of control rabbits (p<0.05).
     1. 这两个剂量均能引起家兔慢性硒中毒,生长缓慢、体重下降,随着给硒次数的增加,血硒水平明显高于对照组(p<0.05,p<0.01,p<0.001),胎肝、胎盘、公兔睾丸等组织硒含量也明显高于对照组(p<0.05)。

The selenium(Se)contents of tea samples from normal, higher and chronic selenosis areas were 0.085,0.206 and 4.027 ppm respectively. The average rates of selenium soaked out from samples of corresponding areas in boiled water were 20.2, 20.8 and 13.5%. The relative distributions of Se~(6+), Se~(4+) and below Se~(4+) in soaking water were observed to be 61.4, 13.8 and 24.8% in samples from normal selenium area, 59.5, 11.3 and 29.2% in samples from higher selenium area and 36.89 9.5 and 53.7 in samples from...

The selenium(Se)contents of tea samples from normal, higher and chronic selenosis areas were 0.085,0.206 and 4.027 ppm respectively. The average rates of selenium soaked out from samples of corresponding areas in boiled water were 20.2, 20.8 and 13.5%. The relative distributions of Se~(6+), Se~(4+) and below Se~(4+) in soaking water were observed to be 61.4, 13.8 and 24.8% in samples from normal selenium area, 59.5, 11.3 and 29.2% in samples from higher selenium area and 36.89 9.5 and 53.7 in samples from chronic selenosis area.Compared with the consumption of other foods, the influence of drinking tea on the daily selenium intake of local population is insignificant However, if the tea grown in chronic selenosis area is brought into low selenium area,it may be of certain significance for the improvement of selenium status of the local population.

本文分析了正常地区、较高硒水平地区和慢性硒中毒地区的28份茶叶样品中硒的含量,并对其在水中溶解度、存在形式以及对硒摄入量的影响进行了研究。三个地区的茶叶样品中总硒含量分别为0.085±0.030,0.206±0.186和4.027±3.033ppm。茶叶中硒的浸出率分别为20.2%,20.8%和13.5%;范围分别为11.9~30.1%,14.2~24.4%和10.0~16.9%。浸出茶水中硒的存在形式,主要有无机Se~(6+),Se~(4+)和Se~(4+)以下硒,在正常地区分别占61.4±12.2%,13.8±7.7%和24.8±14.9%,较高硒水平地区分别占59.5±18.7%,11.3±9.0%和29.2±26.4%;慢性硒中毒地区分别为36.8±8.4%,9.5±3.5%和53.7±11.3%。与当地居民的其它食物的进食量相比,饮茶水对每日硒摄入量的影响甚微。如果把慢性硒中毒地区所产的茶叶转运到低硒地区,似有一定意义。

Changes of pathomorphology in experimental chronic selenosis of Wister rats hadbeen studied. Forty six male wister rats, weighing 105-135 grams were divided intotwo groups. Twenty eight rats in the experimental group were fed basal diet supplem-ented with 10 ppm selenium (se) of sodium selenite, while the eighteenrats of controlgroup were only fed with basal diet. Growth performances of rats, the ratio of liver,kidney, spleen weight per 100 gm of body were determined. On necropsy, both grossand histopathological...

Changes of pathomorphology in experimental chronic selenosis of Wister rats hadbeen studied. Forty six male wister rats, weighing 105-135 grams were divided intotwo groups. Twenty eight rats in the experimental group were fed basal diet supplem-ented with 10 ppm selenium (se) of sodium selenite, while the eighteenrats of controlgroup were only fed with basal diet. Growth performances of rats, the ratio of liver,kidney, spleen weight per 100 gm of body were determined. On necropsy, both grossand histopathological lesions in liver, kidney, spleen and lymph nodes were studied Growth rate in the experimental group was significantly depressed (P<0. 001).Liver and bodyweight ratio was increased (P<0. 01), while kidney and spleen withthe ratio of body weight were increased only at the advanced stage. Gross and histopathological examination revealed that there were marked damagesin liver, kidney, spleen and lymph nodes. Characteristic lesions in the liver wereintralalobular venules and capillary congestion, hepatocellular degeneration and necrosisin early stage. At the advanced stage, epithelium of intrahepatic bile duct proliferationand heptocyte regeneration were the prominent changes. In kidney, there were tubularcell degeneration and necrosis. The major histopathological findings in the spleen.Lymphocytes of white pulp were sparsely distributed, but in the advaned stage thedegree of severity became to be reduced. Hemorrhages and degeneration were commonlesions in lymph nodes. Also, lymph node lesions were gradually replaced by chronicproliferation lymphadenitis.

对46只大鼠慢性硒中毒的病理形态学变化的研究表明:大鼠的生长受到明显抑制;肝体比值增加;肝、肾、脾、淋巴结等实质器官受害严重。肝脏病变,早期以肝小叶间质血管、肝窦及中央静脉的淤血、肝实质细胞的变性坏死为特征,中后期则以胆管上皮细胞的增生及肝实质细胞的再生为特点;肾脏主要表现为实质的退行性病变;脾脏则以白髓组织的损害为主,后期损伤有所减轻;淋巴结早期以变质、出血为主,并逐渐变为慢性增生性的淋巴结炎。
