废纸造纸循环水处理实现零排放

在以废纸为原料的造纸厂里建立了废水生物处理系统处理循环水，合理设计和工艺控制达到了在去除有机污染物的同时，通过生物软化工艺去除水中钙离子的预定目标，有效地消除了循环水系统污染物的积累，从而使循环水可以全部回用，成功地实现了废水的零排放。该工程2002年6月开始启动，2002年11月以来耗水量降低到2．1～2．3m^3／t纸，在纸机车速高于设计车速的条件下生产运行稳定，吨成品纸消耗废纸原料的量降低到1．15t以下。在取得良好污染控制效果的同时，取得很好的节水和节约原材料的经济效益。

活性乳酸菌乳饮品对免疫调节功能的影响

为探讨活性乳酸菌乳饮品对小鼠免疫系统功能的影响,将该饮品按 6.67 ～ 26.66ml/kg BW( 2.5 倍浓缩液)剂量给小鼠灌胃 30 天后,分别检测脾淋巴细胞增殖转化功能( MTT 法),迟发型变态反应性,血清溶血素滴度,碳廓清能力及自然杀伤细胞( NK )杀伤活性.结果表明该乳饮品可明显提高小鼠脾淋巴细胞增殖转化能力,溶血素血清滴度有统计学意义的增加,变态反应性增强,碳廓清能力增强.而 NK 细胞杀伤活性增加不明显,各组间无统计学意义的差异.提示该活性乳酸菌乳饮品具有增强机体免疫功能的作用.     

双歧杆菌活菌颗粒制剂对小鼠肠道菌群的调节作用

双歧杆菌是得到广泛公认的益生菌。它除了能合成多种维生素外,还能在人体肠道内形成一个生物学屏障,有效地抑制、阻止致病菌和条件致病菌在肠道中入侵和定植,从而调整与改善人体肠道中的微生态环境,达到调理肠胃,增强免疫功能,抑制肿瘤和延缓衰老的效果。由于益生菌的特殊生理作用,使国内外医学界纷纷尝试应用益生菌制作保健品。目前,国内对双歧杆菌的基础性研究和活菌制剂的开发都十分活跃,其生物制剂已应用于临床治疗。含双歧杆菌活菌的保健品也深受群众的喜爱。本文观察了保健食品“某双歧杆菌活菌颗粒剂”对小鼠胃肠道菌的调节作用,报告…     

云南省耿马县蔗区土壤主要养分状况分析研究及对策

对云南省耿马县蔗区耕作层土壤养分的测定表明，该县土壤的有机质含量为中等，氮素营养中上，钾素供给中下，磷素供给中下。各村片差别较大，部分土壤养分严重缺乏，土壤明显酸化。土壤主要养分的供给总体上处于中下水平。根据该蔗区土壤养分状况提出相应对策。     

+UVA treatment increases the degree of unsaturation in microalgal fatty acids and total carotenoid content in Nitzschia closterium (Bacillariophyceae) and Isochrysis zhangjiangensis (Chrysophyceae)

The production of metabolites by microalgae is affected by environmental conditions in which they are living. The metabolic responses of two marine microalgae, Nitzschia closterium and Isochrysis zhangjiangensis, to a 3-day UVA-stress and 3-day UVA-recovery treatment were compared, based on their growth, fatty acid profiles and content of total carotenoids. When cultured under photosynthetically active radiation, coupled with UVA treatment, both microalgae underwent a significant increase in their growth during the UVA-recovery period compared to the control. The proportions of polyunsaturated fatty acids, including linoleic acid and eicosapentaenoic acid, as well as total carotenoids, were significantly increased in both microalgae, mainly in the UVA-stress period, but not the UVA-recovery period. The metabolic responses of the two microalgae to UVA treatment were species-dependent and could be utilised to produce microalgal biomass rich in polyunsaturated fatty acids and carotenoids for use as functional food ingredients.     

Protective effect of bamboo shoot oil on experimental nonbacterial prostatitis in rats

This study aim to investigate the protective effects of bamboo shoot oil (BSO) and its mechanisms on nonbacterial prostatitis (NBP). The anti-prostatitis effect of BSO were evaluated by prostate weight, acid phosphatase, density of lecithin corpuscles (DLCC), white blood cell count (WBC), and prostatic histomorphological parameters using Xiaozhiling-induced experimental NBP model in rats. The mechanisms of anti-prostatitis effect were assessed using functionally focused cDNA microarray and real-time PCR. BSO could significantly inhibited absolute prostate weight, prostate index, total acid phosphatase, prostatic acid phosphatase, WBC and the expression levels of thirty up-regulated genes, while BSO could significantly increased DLCC and the expression levels of fifteen down-regulated genes. Histologically, BSO treatment significantly suppressed the severity of the lesion in NBP-induced rats. Thus, BSO may be useful for treatment of NBP, as it may inhibits prostate inflammation in NBP patients by affecting the expression of inflammatory cytokines, their receptors, and related genes.
