Theresearch on it showed that there are many trace elements in maifanite. In this paper, 36 traceelements in maifanite were determined by outer cover electrode atomic emission spectrometry, and thedetermination conditions were studied systematically. The results show that the concentrations ofelements, which are beneficial to human health, are higher, and the elements harmful to peoplehealth such as As, Cd, Hg, Cr, and Pb are tiny in maifanite. The precision and the accuracy werealso discussed.展开更多

The two groups had similar nutrition intake. Blood, feces, urine and drain samples were collected to measure zincum, cuprum and ferrum as well as glucose levels. Accumulative intake, excretion and balance of zincum, cuprum and ferrum, apparent absorption （AA） and apparent utilization （AU） of zincum, cuprum and ferrum, blood glucose levels and adverse events were estimated. RESULTS： There were no differences in accumulative intake and drain excretion between the two groups. The feces excretion and accumulative excretion of cuprum were lower in the rhGH group （P 〈 0.05）. The urinary excretion of zincum, cuprum and ferrum was all significantly decreased in the rhGH group （P 〈 0.05） and the accumulative balance of zincum, cuprum and ferrum was improved compared with the placebo group （P 〈 0.05）. AA of cuprum in the rhGH group was almost twice as much as the placebo group （P 〈 0.05）, and AU of zincum, cuprum and ferrum was all improved in the rhGH group （P 〈 0.05）. The mean blood glucose level was significantly higher in the rhGH group than in the placebo group from d 3 to d 6 after operation （P 〈 0.05）.improves the retention of zincum, cuprum and ferrum and decreases the excretion of zincum, cuprum and ferrum, improves the balance of zincum, cuprum and ferrum, and promotes the AA and AU of zincum, cuprum and ferrum, rhGH can be well tolerated without significant adverse effects and the blood glucose level can be well controlled.展开更多
