The experimental cardiomyopathy was induced by i. p. administration of adriamycin.The hcart failure and cardial lesions became more serious by additional administration of the trace element manganese.The emount and activity of selenium and glutathione peroxidase were also deeply depressed by the cumulation of manganese in erythrocyte.

腹腔注射阿霉素可以使大鼠产生实验性心肌病。大剂量注锰可以加重阿霉素的心脏毒性作用,加重心力衰竭和心肌细胞与间质水肿。红细胞内锰的蓄积可以导致硒和含硒酶的含量与活性发生改变。錳亦可以明显抑制大鼠生长。

The experiment was conducted by using two groups of piglets (experiment group 28, control group 14) to determine the effects of low-selenium nutrition on some immune organic structures and immune functions. The results showed that the tissue selenium concentrations and their glutathine peroxidase (GSH-px)activity decreased significantly in experiment group when compared with the control (P<0.01 or P<0.05). There was a highly positive correlation between the immune organic selenium levels and its GSH-px activity....

The experiment was conducted by using two groups of piglets (experiment group 28, control group 14) to determine the effects of low-selenium nutrition on some immune organic structures and immune functions. The results showed that the tissue selenium concentrations and their glutathine peroxidase (GSH-px)activity decreased significantly in experiment group when compared with the control (P<0.01 or P<0.05). There was a highly positive correlation between the immune organic selenium levels and its GSH-px activity. The percentage of acid-nonspecific α-naphthyl esterase (ANAE) positive lymphocytes and the response ability of the lymphocytes to the phytohaemagglutinin (PHA) in blood of the experiment group showed significant differcnces as compared wtih the control (P<0.05 or P<0.01). The changes of malnutrition of the immune organs were observed in experiment group. They showed notably vacuolar degeneration and nuclear breaking or solution of lymphocytes, and focal or diffuse necrosis of the lymphotic tissues.

应用42头仔猪进行了低硒营养对仔猪某些免疫器官组织结构和免疫功能影响的研究。结果表明,实验组仔猪组织含硒量和含硒酶(Se GSH-px)活性均显著低于对照组(PC1或P<0.05)。被检免疫器官的含硒量和舍硒酶活性之间呈正相关,低硒饲养时两者同步降低。与对照仔猪比较,实验组仔猪外周血酸性非特异性酯酶阳性[ANAE~+]淋巴细胞的百分率和该细胞对植物血凝素(PHA)的反应能力显著降低(P<0.05或0.01)。病理组织学检查可见,实验组仔猪被检免疫器官发生营养不良性变化。主要表现为淋巴组织的局灶性或弥漫性坏死,淋巴细胞空泡形成和核崩解或核溶解。

The effects of manganese on selenium content and glutathione peroxidaseactivity in blood and myocardium, and on selenium excretion in growing ratswere studied to ferret out the interaction of the two essential trace elements.Manganese dichloride (40mg/kg of MnCl2.4H2O) was administered daily to a group of 17 rats for 35 days intraperitoneally. An obvious increase in manganese content in serum and myocardium was induced. However, selenium levels in the two tissues of manganese-treated rats were significantly...

The effects of manganese on selenium content and glutathione peroxidaseactivity in blood and myocardium, and on selenium excretion in growing ratswere studied to ferret out the interaction of the two essential trace elements.Manganese dichloride (40mg/kg of MnCl2.4H2O) was administered daily to a group of 17 rats for 35 days intraperitoneally. An obvious increase in manganese content in serum and myocardium was induced. However, selenium levels in the two tissues of manganese-treated rats were significantly lower than the controls. From the 14th day on, glutathione peroxidase activities in whole blood of manganese-treated rats were below the controls, and on the 35th day, the activities of the selenium-containing enzyme in blood and myocardium were reduced by 29.33% (P<0.001) and 20.48% (P<0.001) respectively. Negative correlations between manganese and selenium and between manganese and glutathione peroxidase in the two tissues were found.75Se-selenite was given orally to another group of 6 rats after treatment with manganese for 7 days, and a higher level of 75Se in urine was observed during the slow phase of excretion.In conclusion, excessive exposufe to manganese increases selenium excretion,thereby depleting tissue stores of selenium and the activities of selenium-containing enzyme.

鉴于贫硒与克山病发病有密切关系以及一些病区的人群既贫硒又富锰,本文研究了锰对大鼠硒代谢的影响。经腹腔给大鼠注射40mg/kg氯化锰5周,致血清和心肌锰含量明显增高,而血清和心肌硒含量以及全血和心肌谷胱甘肽过氧化物酶活性却显著降低。组织锰含量与硒含量和谷胱甘肽过氧化物酶活性呈负相关。在给予氯化锰的第7天,经胃管给予~(75)硒,锰组大鼠在服~(75)硒之后7天中总排硒量显著高于对照组大鼠,主要是由于锰促进慢相尿硒排泄所致。结果表明,锰对硒代谢有明显影响,即通过增加硒排泄量而致血、心肌硒含量和含硒酶活性显著降低。
