A one time large dose of selenium with label was injected to Se deficient rats. Platelets, liver and PPP were assayed for GSH-Px activity and determined the uptake of Se. The results showed that platelet GSH-Px activity would also be a good index in reflecting the abrupt change of Se status. It can be changed rapidly and significantly. The results also demostrated that platelet GSH-Px trends to reflect GSH-Px in the liver which is the organ with the most labile Se pool. Platelet GSH-Px...

A one time large dose of selenium with label was injected to Se deficient rats. Platelets, liver and PPP were assayed for GSH-Px activity and determined the uptake of Se. The results showed that platelet GSH-Px activity would also be a good index in reflecting the abrupt change of Se status. It can be changed rapidly and significantly. The results also demostrated that platelet GSH-Px trends to reflect GSH-Px in the liver which is the organ with the most labile Se pool. Platelet GSH-Px may be a suitable index of selenium status for determine the bioavilability of selenium from various food sources in short-term human studies. When different form of Se was given, GSH-Px activity in platelet, liver and PPP expressed on a protein basis was similar in the selenite and selenomethionine administered groups. However, Se uptake of platelet, liver and PPP was greater in the selenomethionine versus the selenite group, indicating that selenomethionine was being taken up nonspecifically into platelet protein other than GSH-Px. This fact was also shown by the lower platelet GSH-Px specific activity. There might be another metabolic way for Se. More work is needed to clarify metabolism of selenium in tissue.

给缺硒大鼠一次大剂量注射含~(75)硒的硒化合物。测定血小板,肝、血浆谷是胱甘肽过氧化物酶活性及~(75)硒含量。结果表明,血小板谷胱甘肽过氧化物酶活性反映一次大剂量硒摄入时的一个良好指标。同时证明血小板GSH-Px变化与肝GSH-Px变化一致。以两种不同形式硒化合物(亚硒酸钠和硒蛋氨酸)给予缺硒大鼠,两组大鼠血小板、肝、血浆中GSH-Px活性是相似的,但~(75)硒含量亚硒酸钠组显著低于硒蛋氨酸组,由此表明,硒蛋氨酸中部分硒没有掺入到血小板的GSH-Px中去,推测在体内硒可能存在其它代谢途径,这是很值得探讨的问题。

The urinary Se and hydroxylysine contents were determined in 162 cases from Kasehin-Beek disease affected and non- affected areas.The results showed that the urinary hydroxylysine outputs were lower in children with lower Se levels than with highter Se ones.There was a close relationship between urinary Se and hydro- xylysine outputs (r=0.97,n′=3,p<0.01). Both hydroxylysine and hydroxyproline contents in urine were greatly decrea- sed in children with Se deficiency.This suggested...

The urinary Se and hydroxylysine contents were determined in 162 cases from Kasehin-Beek disease affected and non- affected areas.The results showed that the urinary hydroxylysine outputs were lower in children with lower Se levels than with highter Se ones.There was a close relationship between urinary Se and hydro- xylysine outputs (r=0.97,n′=3,p<0.01). Both hydroxylysine and hydroxyproline contents in urine were greatly decrea- sed in children with Se deficiency.This suggested that the hydroxylations of lys- ine and Proline might be inhibited by Se deficiency in the children with low Se status.

1.大骨节病患区和邻近非患区不同硒水平儿童尿羟赖氨酸排出情况不同,凡是尿硒排出量低的儿童,其尿羟赖氨酸排出量也低,二者存在高度正相关关系。2.低硒儿童尿羟赖氨酸排出减少被认为可能与前α-肽链上赖氨酸羟化不全有关。3.本文着重对大骨节病儿童分组指标的选择做了详细讨论,指出合理分组是获得生化代谢变化正确信息的基础。

In order to study the effect of a low Se status on the fluidity and activities of membrane bound enzyme of cardiac sarcolemma ( CS ) , a comparative study on the changes of fluidity and the acti vi ties of Na +-K + -ATPase and 5' -nucleotidase of CS of rats fed on grain from Keshan Disease ( KD ) areas and the same grain supplemented with selenium respectively was carried out. CS was isolated by the method of sucrose gradient ultracentrifugation. Enzyme marker analysis and electron microscope observation were used to determine the purity of the preparation. Fluidity of CS was measured by the fluorescence polarization method using diphenyihexatriene as a fluorescent probe. The results show that the specific activity of CS fraction is ten-fold greater than the ho-mogenate. Electron micrographs of CS fraction indicate a high degree of vesi-culation similar to that reported by others. Fluidity and the activities of Na+-K +-ATPase and 5'-nucieotidase of CS of the rats fed on grain from KD area were significantly lower than that of the controls and the selenium contents of myocardium were reduced. These changes could be prevented or returned to the control level when the rats were fed with the same grain supplemented with Se. Based on the results of our study, it is concluded that the activities of Na+ -K+-ATPase and 5'-nucleotidase of CS in a Se-poor status were reduced probably due to the membrane fluidity abnormality.

本文对比观察了低硒的克山病病区粮和补硒的克山病病区粮喂养大鼠其心肌细胞膜流动性及膜结合酶Na~+—K~+—ATP酶、5′—核苷酸酶活性的变化。实验结果表明,克山病病区粮喂养的大鼠心肌细胞膜流动性及膜结合酶活性均降低;给病区粮补硒0.25ppm后可使上述心肌细胞膜的异常变化得到一定的恢复,据此认为细胞膜流动性异常可能是低硒对膜结合酶影响的中间环节。是低硒导致细胞膜功能障碍的基础。
