奇妙的保健因子—褪黑素

褪黑素的英文名为Melatonin,学名N—乙酰基—5—甲氧基色胺,分子式C_(13)H_(16)N_2O_2。褪黑素是由松果体分泌的一种激素,具有调节睡眠、延缓衰老、增强免疫、抑制肿瘤、预防心血管疾病及其它多种调节功能。1 褪黑素与睡眼 褪黑素与睡眠周期有着密切关系。研究发现,褪黑激素在一天24小时中并不是均匀分泌的,而是有昼少夜多的规律。具体数据见表1。 表1 30岁健康成人一昼夜的血清褪黑素含量变化     

Expression and localisation of claudin-1, -2, -3, -4, -5, -7 and -10 proteins in the normal canine mammary gland

The recently identified claudins are dominant components of tight junctions, responsible for cell adhesion, polarity and paracellular permeability. Certain claudins have been shown to have relevance in tumour development. The aim of the present study was to analyse the expression of claudin-1, -2, -3, -4, -5, -7 and -10 in normal canine mammary glands. Samples from the inguinal mammary regions of 20 non-castrated, 1-13 years old female dogs were studied. Immunohistochemical analysis was performed on conventional specimens and tissue microarrays. The results of the immunohistochemical reactions detecting claudins in tissue sections were photodocumented. The immunoreactivity of claudins was quantitatively analysed on digital images using Leica QWin morphometry software. Intense membranous immunolabelling was found for claudin-1, -3 and -7, intense membranous with non-granular cytoplasmic immunolabelling for claudin-2, moderate membranous immunolabelling for claudin-4 and -5, and weak membranous immunolabelling for claudin-10. The occurrence of tight junctions was confirmed by ultrathin section electron microscopy. The available data suggested that claudins might be proteins preserved throughout the evolution of mammals. The results of our study support the concept that they are indeed preserved, since the same type of claudins, in identical distribution, could be detected in our canine mammary tissue samples as could be found in human mammary tissue.     

啤酒酵母中(1-3)-β-D-葡聚糖提取与理化性能分析

(1-3)-β-D-葡聚糖是一种极富生物活性的多糖，它表现出很强的刺激免疫和抗肿瘤活性，是一种良好的生物反应调节剂．在啤酒酵母细胞壁中，含有大量的(1-3)-β-D-葡聚糖，我国的酵母资源十分丰富，估计年产啤酒酵母3～5万吨(干基)。可是我国啤酒制造业对啤酒废酵母没有很好的重视与利用。啤酒废酵母作为废弃物排人下水道或以低廉的价格售作饲料，造成环境污染和资源浪费。因此酵母提取物的研究与开发具有重要意义。     

德国汉诺威国际畜牧展报告

<正>上周我们参加了德国汉诺威国际畜牧展。我们看到:德国汉诺威国际畜牧展两年举办一次,展会所在的大展览中心有超过20个大型建筑。这是我们参加过的最大的畜禽展。有数百家参展商。有很多非常大的展位,特别是一些养猪设备公司。我们估计有些公司花了上百万美元来参展并布置展位。有一些令人印象深刻的展位,似乎养猪设备行业展开了军备竞赛来布置更大更漂亮的展位方面。必达公司为其它公司设置了高门槛。

Investigation of multiple Felis catus papillomavirus types (-1/-2/-3/-4/-5/-6) DNAs in feline oral squamous cell carcinoma: a multicentric study

Recent evidence suggests a possible association of Felis catus papillomavirus type 2 (FcaPV-2) DNA with feline oral squamous cell carcinoma (FOSCC). In this study, type-specific PCR targeting two genes (L1/E6 or E1/E6) of FcaPV-1/-2/-3/-4/-5/-6 was performed to detect viral DNA in a large amount of FOSCC samples collected in Italy and Austria. FcaPV-1/-2/-3/-4/-5 were detected in 7/113 (6.2%), 7/93 (7.5%), 6/113 (5.3%), 1/113 (0.9%) and 2/113 (1.8%) specimens, respectively, with different prevalences in Italian vs. Austrian samples, whilst FcaPV-6 went undetected. Our results confirms that FcaPV-2 is the most prevalent in FOSCC, followed by FcaPV-1/-3 and suggest that FcaPVs have variable circulation rates in European countries.     

HM-强效复合微生态制剂的研究

在人和动物体内微生物定居的数目 ,多于动物本身的组织细胞数 ,在正常情况下 ,它们相互依赖、相互制约 ,维持着有益于人和动物健康的生态环境。正常菌群参与机体生理、免疫、营养、消化、吸收、抗肿瘤以及生物拮抗等一系列代谢过程。人类长期、广泛、大量使用抗生素 ,虽挽救了无数生命 ,但它在杀死病原菌的同时 ,也杀死了有益菌 ,引起二重感染和内源性感染。长期无节制地使用抗生素 ,使人和动物产生耐药性 ,治疗效果越来越不理想 ,免疫功能也因此而下降 ,引起发病和死亡。近年来科学研究认为 ,人类常见的癌症、畸形及其他的一些慢性病的发生…
