精索静脉曲张是男性中一种常见的疾病,也是造成男性不良的重要病因。本文对20例精索静脉曲张不育患者精液中铜、锌元素进行了检测,结果表明,患者精液中铜、锌含量与正常对照组无显著差异,精索静脉曲张不育与精液中铜、锌含量无相关性存在。同时提示,通过补锌治疗男性不育不可一概而论。 相似文献

Ac susceptibility at low temperatures of Pr0.75Na0.25Mn1-xFexO3 (0 ≤ x ≤ 0.30) is investigated. The peak value of the real component of ac susceptibility χ' at the freezing temperature Tf is suppressed with the increasing frequency. The peak value of χ' shows a linear relation between Tf and the logarithm of the frequency ω. The normalized slope P = ΔTf/TfΔlgω, which is much lower than canonical insulating spin glass systems in which 0.06 ≤ P ≤ 0.08. The peak value of the imaginary component of the ac susceptibility χ' at Tf for the x = 0, 0.02, 0.30 samples increases with increasing frequency, suggesting a cluster glass ground state with a coexistence of charge-ordered phase and correlated ferromagnetic clusters in spin glass matrix. The peak value of χ' at Tf for the x = 0.10 sample decreases with increasing frequency, suggesting a phase separation ground state. The peak value of χ' at Tf for the x = 0.05 sample decreases with increasing frequency for ω ≤ 52 Hz and increases subsequently till 701 Hz, and then decreases with further increasing frequency for ω ≥ 1501 Hz. This complex behaviour is ascribed to the competition between the effects of large and little ferromagnetic clusters in the sample. The ground state of x = 0.05 sample is a transition state from cluster glass to phase separation. 相似文献

慢性前列腺炎及其不育患者精液铜、锌元素的初步研究 总被引:4,自引:0,他引:4
慢性前列腺炎是男性中一种常见的疾病。会造成男性生育力的降低。本文对6例无生育力和18例有生育力的慢性前列腺炎患者精液中铜,锌元素进行了检测。结果表明,天生育力的患者精液中铜,锌含量与有生育力患者的含量无显著差异。所以,慢性前列腺炎不育与精液中铜,锌含量无相关性存在。 相似文献
