Aim: To assess the protective efficacy of vitamin E to counteract the reactive oxygen species (ROS) mediated damage onsperm motility, viability and lipid peroxidation. Methods: Human semen samples were obtained from the local hospi-tal. The split seminal fractions freed of seminal plasma were reconstituted in Ringer-Tyrode and subjected to varied vita-min E concentrations (0.1 - 2 mmol/L). Results: Dose-dependent improvement in both motility and viability accom-panied by concomitant decrease in malondialdehyde (MDA--an end product of lipid peroxidation) following vitamin Esupplementation was noticed. Conclusion: vitamin E protects against the ROS mediated damage on *** E supplementation could be of clinical importance for prolonged spermatozoal storage whenever needed.

The s recent works on the improvement of the Strain Range Partitioning(SRP) method and its application to the life prediction of high temperature structural components are summarized. Examined components are divided into three groups, that is, components in the steel production plants, in the automobile and in the fossil power plants. Based on the results of the inelastic analysis and the creepfatigue properties of the material, which were obtained by ij(=PP,PC, CP, CC) tests, the effects of the material properties, operating conditions and configuration of components were quantitatively evaluated to select the most effective measures for the thermal fatigue life extension. The SRP has been successfully applied until now to the life prediction and extension of the actual structural components subjected to thermal cycling by the s.

The two procedures based on the strain range partitioning approach are proposed for evaluating the remaining life by measuring the surface crack length. Both the procedures require that the material parameters describing the creepfatigue damage rule built and modified by the s and the strain waveform applied have been clarified before the evaluation. One of the procedures can be used only when the total number of the operation cycles n are known, whereas the other is useful even when n is unknown, though it needs the additional crack length measurement. In the latter the surface crack length must be measured not only at n but also at n+n, where n is a given interval of cycles. The results of their application to Mod.9Cr1Mo and 316LC steel smooth specimens subjected to the ij type creepfatigue loading are shown.
