This study investigated the effects of hormonal status; metabolic changes of restricted ewes during late pregnancy on the ovine fetus growth; development. One hundred Mongolian ewes, synchronized for oestrus; mated, were divided into three groups; offered 0.175 MJME·kgw[0.75]·d[1] (Restricted Group 1, RG1), 0.33 MJME·kgw[0.75]·d[1] (Restricted Group 2, RG2); ad libitum access to feed (Control Group, CG) during their late pregnancy respectively. The results suggested that with the supply of exogenous energy decreasing during late pregnancy, maternal body weight; net body weight loss in RG2; RG1 were lower than those of CG (Ps0.01). The insulin; IGF-1 concentrations of ewes in RG2; RG1 tended to be lower than those of CG (P>0.05), but the GH concentrations in RG2; RG1 were enhanced; there was significant difference between RG1; CG on d 120 of gestation (P0.05). However, the NEFA; FAA concentrations of ewes in RG1 were reduced from d 90 to d 120 of gestation, then enhanced from d 120 to d 140 of gestation. During the late pregnancy, with the supply of nutrition decreasing, the negatively physiological; biochemical maternal reactions to restriction became worse, which significantly reduced the average lamb birth weight; daily growth rate of fetus in RG2 (P<0.05); RG1 (P<0.01).

The study aims to reveal phylogenetic and evolutionary relationship between aerobic anoxygenic phototrophic bacteria（AAnPB） and their relatives,anaerobic anoxygenic phototrophic bacteria（AnAnPB） and nonphototrophic bacteria（NPB,which had high homology of 16S rDNA gene with AAnPB and fell into the same genus）,and validate reliability and usefulness of farnesyl pyrophosphate synthase（FPPS） gene for the phylogenetic *** genes with our modified primers and 16S rDNA genes with general primers,were amplified and sequenced or retrieved from GenBank *** contrast to 16S rDNA gene phylogenetic tree,AAnPB were grouped into two clusters and one branch alone with no intermingling with NPB and AnAnPB in the tree constructed on *** branch of AAnPB,in both trees,was located closer to outgroup species than AnAnPB,which implicated that some AAnPB would be diverged earlier in FPPS evolutionary history than AnAnPB and *** AAnPB and NPB were closer located in both trees and this suggested that they were the closer relatives than *** codon usage in FPPS with phylogenetic analysis,the results indicates that FPPS gene and 16S rRNA gene have similar evolutionary pattern but the former seems to be more reliable and useful in determining the phylogenic and evolutionary relationship between AAnPB and their *** is the first attempt to use a molecular marker beside 16S rRNA gene for studying the phylogeny of AAnPB,and the study may also be helpful in understanding the evolutionary relationship among phototrophic microbes and the trends of photosynthetic genes transfer.

从内蒙古地区传统谷物发酵食品——酸粥中分离并鉴定的13株乳酸杆菌中筛选具有抑菌活性的菌株,并对其抑菌能力及抑菌物质的特性进行研究。结果表明,菌株NSZL-2(鼠李糖乳杆菌***)和NSZL-12(植物乳杆菌***)对指示菌具有较高的抑菌活性,且抑菌能力主要来自菌体的发酵代谢产物。排除酸和过氧化氢的干扰后代谢产物仍具有抑菌活性,且抑菌物质对热具有很高的稳定性。代谢产物经蛋白酶K、胃蛋白酶、胰蛋白酶、木瓜蛋白酶、过氧化氢酶、溶菌酶处理后,抑菌能力均有不同程度的降低,说明抑菌物质对蛋白酶敏感,故判定抑菌物质中有蛋白质类细菌素。

在短花针茅荒漠草原,对比研究了不同放牧制度群落植物重要值和多样性,研究结果表明:划区轮牧和对照区重要值较高的植物为短花针茅、无芒隐子草、碱韭和糙隐子草,自由放牧区1年生植物重要值较高;2002年Shannon-Wiener、Simpson和Pielou群落多样性指数自由放牧区偏高于轮牧区,但从3种指数的影响因子重要值的分布上看,轮牧区主要分布在建群种和优势种上,自由放牧区分布在建群种、伴生种和1年生植物上,可以认为轮牧条件下群落环境更稳定。
