AIM: To study the immunological effects of physiological doses of purple sweet potato leaves(PSPL). METHODS: The randomized crossover study(two periods, each lasting for 2 wk) involved 16 healthy non-smoking adults of normal weight. The 6-wk study consisted of a run-in(wk 1) PSPL diet(daily consumption of 200 g PSPL) or a control diet(low polyphenols, with the amount of carotenoids adjusted to the same level as that of PSPL)(wk 2-3), washout diet(wk 4), and switched diet(wk 5-6). Fasting blood was collected weekly in the morning. T-lymphocyte function was assessed via the proliferation and secretion of immunoreactive cytokines. Salivary IgA secretion and the specific cytotoxic activities of cytotoxic T lymphocytes and natural killer(Nk) cells were determined. RESULTS: The plasma β-carotene level increased with time in both groups, while the plasma polyphenol level decreased in the control group, and no significant difference was detected between the two groups. Although plasma polyphenol levels did not significantly increase in the PSPL group at the end of the study, they were significantly elevated in urine. PSPL consumption produced a significant increase in proliferation responsiveness of peripheral blood mononuclear cells(PBMC) and their secretion of immunoreactive IL-2 and IL-4. As well, lytic activity in Nk cells was elevated in a time-dependent fashion. Salivary IgA secretion significantly decreased in control group after 2 wk, and returned to baseline following dietary switch to PSPL. CONCLUSION: Consumption of PSPL modulates various immune functions including increased proliferation responsiveness of PBMC, secretion of cytokines IL-2 and IL-4, and the lytic activity of Nk cells. The responsible determinants of PSPL remain to be elucidated, as does the biological significance of the present observations.

Cu(x)/Ni(y)/glass bi-layer films, with x ranging from 10 to 310 A andy = 85 A, were made by the vapor evaporation method in a good vacuum. The surface morphology of each bi-layer was examined by an atomic force microscope (AFM). The results show that when x = 10 and 40 A, respectively, there are, in particular, a large number of Cu nanoparticles (or nano-islands) forming on top of the Ni *** a result, we observed considerable enhancement of either the polar kerr rotation (θk) or the extraordinary Hall coefficient (Rs) at these two thicknesses (e.g. checking the figure below). As well known, the penetration depth (δp), of the polarized electrons, crossing the Cu/Ni interface from the Ni to the Cu layer, is of the order of the electron mean free path, i.e. δp =(3/8)[Cu≈90 A. in the Cu layer. *** strong enhancement of θk is due to the enhanced surface plasma resonance effect on the polarized Cu nanoparticles. Moreover. the formation of Cu nanoparticles roughens the bi-layer's surface *** means the enhancement of Rs is due to the increase of the surface resistivity ρs.

应用已知电荷性质的土壤、离子交换树脂和粘土矿物,测定了氢、钾和钠离子的悬液效应。结果表明,两性物质在pH高时有酸性悬液效应,在pH低时有碱性悬液效应,在等电点时,悬液和平衡清液间的△pH为零。玻璃电极或甘汞电极的盐桥的位置的改变,都可引起悬液效应;在pH较高时,主要是玻璃电极起决定性影响,而在pH较低时,则以甘汞电极的贡献为主。玻璃电极所引起的△pH总是负号,而甘汞电极所引起者则在pH高时为负,低时为正。悬液固相的电荷符号,和以△pH表示的液接电位的符号密切相关。颗粒带电的多少,也影响到液接电位的大小。悬液中吸附性离子的价数、盐桥中电解质的种类以及接触状况等,都对液接电位发生影响。在pH较高时,悬液中的氢和氯离子的活度积并不与其平衡液中者相等。
