乌龙茶和茉莉花茶对小鼠免疫功能的影响

乌龙茶和茉莉花茶对小鼠的免疫功能试验结果表明,10%乌龙茶或茉莉花茶灌胃均能引起小鼠的胸腺缩小。1%花茶灌胃,小鼠的脾淋巴细胞自发性~3H-TdR掺入及 Con A 刺激的淋巴细胞转化率均明显增高,但乌龙茶与10%茉莉花茶则未见这种作用。10%乌龙茶能抑制小鼠SRBC溶血素抗体的产生,而花茶对抗体的产生影响不大。1%花茶可使小鼠外周血 ANAE 阳性细胞增多。此外,还对茶叶影响机体免疫功能的机理进行了讨论。

Polysaccharide isolated from fermented barley activates innate immune system and anti-tumor metastasis in mice

To develop novel functional ingredients, a polysaccharide called BF-E2-P was purified from fermented barley and its antitumor activity was investigated. In the experimental lung metastasis model of colon 26-M3.1 carcinoma cells, intravenous administration of BF-E2-P (500 μg/mouse) 2 days before inoculation resulted in inhibition of metastasis by about 76%, and the extent of inhibition was dose-dependent. To demonstrate the anti-metastatic activity of BF-E2-P, we tested whether BF-E2-P could activate the innate immune system. Stimulation of macrophages by BF-E2-P resulted in cytokine production. In a co-culture of macrophages and cancer cells, BF-E2-P altered the pattern of cytokine production, suggesting that BF-E2-P affects the polarization of macrophages. In addition, intravenous administration of BF-E2-P augmented the natural killer (NK) cell-mediated cytotoxicity against cancer cells. It also increased the production of IFN- γ and granzyme B. In conclusion, BF-E2-P activates NK cells and macrophages, resulting in the enhancement of host-defense against tumor growth.     

Hydathode function and changes in contents of elements in eddo exposed to zinc in hydroponic solution

To explore the zinc stress response in eddo, plants were grown for 15 d in hydroponic solutions containing 1 (control), 200, and 1000 μM zinc, and the hydathode function and changes in the contents of various elements in these plants were investigated. Under 1000 μM zinc, the dry weights of leaf blades and roots are decreased by 17 and 42%, respectively. The zinc contents in leaf blades, petioles, corms, and roots increased with increasing zinc levels in the solution. The zinc content in roots was 6.57 mg g^?1 dry weight, which was 2.8–4.3 times higher than in other plant parts under 1000 μM zinc. These results demonstrate that the severe root damage occurring under 1000 μM zinc is due to higher zinc content in the roots. Under zinc stress, the contents of iron and copper in roots increased, but the contents of magnesium and calcium in petioles, corms, and roots, iron in leaf blades and corms, and manganese in petioles and corms decreased. In the guttation fluid, the concentrations of zinc, magnesium, and potassium increased, while the iron concentration decreased under 1000 μM zinc. Thus, elemental changes occurred in the guttation fluid as well as in different plant parts in eddo. In the 200 and 1000 μM zinc treatments, the amount of zinc eliminated via guttation was 2.8 and 8.5 times higher, respectively, than in the control. The results indicate that guttation partly contributes to the excretion of excess zinc under zinc stress conditions.     

Effects of poultry manure on soil solution electrical conductivity and early growth of Monochoria vaginalis

We investigated the effect of poultry manure (PM) on the occurrence and early growth of Monochoria vaginalis in relation to soil solution electrical conductivity (SSEC). PM was applied at rates corresponding to 0 g of nitrogen (N) m^?2 (PM-0), 1 g N m^?2 (PM-1), 3 g N m^?2 (PM-3), and 5 g N m^?2 (PM-5). At 7 d post-seeding, the soil solution was sampled to measure EC, and also the emergence and growth of M. vaginalis were evaluated. The emergence rate of M. vaginalis decreased with increasing application rate of PM and SSEC. SSEC was significantly negatively correlated with the emergence rate of M. vaginalis seedlings. The average leaf number and length of M. vaginalis did not differ between PM-0, PM-1, and PM-3, but were significantly lower in PM-5. In summary, PM would allow to better control the emergence and early growth of M. vaginalis.
