The activities of 5'-nucleotidase, 2'-nucleotidase, alkaline phosphatase, and acid phosphatase were measured in rat and autopsied human brains. The four phosphatases in the rat brain showed little change in activity after death. The activities of adenosine-producing enzymes were compared in various parts of rat and human brains. When phosphatase activity was measured at pH 7.5, 5'-nucleotidase showed the highest activity in the most parts of the brain. The activity of 2'-nucleotidase and that of nonspecific phosphatase were almost the same at pH 7.5. However, higher phosphatase activity was observed in all parts of the brain when nonspecific phosphatase activity was measured at pH 10.0 or 5.5. High specific activity of 5'-nucleotidase in the brain was detected in the membranous components, especially in the synaptic membranes. The activity of 2'-nucleotidase was distributed in the soluble and synaptosomal fractions. The highest activity of both alkaline and acid phosphatases was recovered in the crude mitochondrial fraction, with the highest specific activity in the microsomal fraction. Phosphatase activity was distributed widely in the rat brain. The activity of 5'-nucleotidase was high in the medulla oblongata, thalamus, and hippocampus, but low in the peripheral nerve, spinal cord, and occipital lobe. The activity of 2'-nucleotidase was high in the vermis and frontal lobe. The highest acid and alkaline phosphatase activities were detected in the frontal lobe and in the olfactory bulb, respectively. The distribution of the four phosphatases in the autopsied human brain was similar to that in the rat brain. The highest 5'-nucleotidase activity was observed in the temporal lobe and thalamus.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

严重缺碘对体质及遗传性状影响的研究   总被引:3,自引:2,他引:1  
对严重缺碘地区一个容貌特殊,身材较矮,智力低下的人群进行了体质特征及遗传性状的研究,并与国内有关本地区的调查资料进行了对照,提出人类体质特征和遗传性状除与人种、地理环境异同直接相关外,人体不可缺少的微量元素的摄入水平在一定程度上对其也产生影响。并且认为同一人种、民族居住同一地理位置所产生的体质差异应从水文、地质、生活方式、生活水平的不同进行综合分析。  相似文献

目的分析许昌市2009—2013年麻疹流行特征和监测系统运转状况,为加速消除麻疹制定策略及措施提供科学依据。方法利用描述性流行病学方法对许昌市2009—2013年麻疹监测系统资料进行统计分析。结果许昌市2009—2013年累计报告麻疹病例675例,年均报告发病率为3.16/10万。全市8个县、市区均有病例报告,病例数主要集中在禹州市,占总病例数的55.56%;发病呈明显的季节性分布,主要集中在2—5月份,占总病例数的73.48%;病例主要集中于0~6岁儿童,占总病例数的85.63%,其中1岁以下婴幼儿占总病例数的50.22%;8月龄~14岁麻疹病例中有确切免疫史者仅占38.58%。随着监测系统及时性和特异性逐年提高,48 h完整调查率由2009年的88.32%上升至2012年的100%;血标本3 d内送达率由2009年的51.68%上升至2013年的100%;实验室结果 7 d内报告率由2009年的52.80%上升至2013年的100%;血标本采集率从2009年48.86%上升至2013年的100%;暴发血清学确诊率、病原学标本采集率均上升至100%。2009—2013年麻疹监测系统敏感性低,排除病例报告发病率为0.49/10万~1.43/10万。结论 2009—2013年许昌市麻疹发病率下降,小年龄组发病构成增加。监测系统运转综合质量逐年提升,但敏感性低。今后应进一步加强麻疹类疫苗接种与管理,提高人群免疫水平;加强医疗机构传染病报告与管理,提高监测系统敏感性,防止传染源扩散。  相似文献

大鼠动情周期中生殖轴系微循环血量的变化   总被引:1,自引:0,他引:1  
吴素英  张珉 《生理学报》1990,42(5):509-513
本文采用放射性生物微球技术,对雌性大鼠动情周期中丘脑下部-垂体-卵巢轴系的微循环血量进行了测量。结果指出,周期各期丘脑下部和垂体的血流量无显著差异(p>0.05)。卵巢血流量在动情后期最大,动情期最小,两期血流量的差异显著(p<0.02)。子宮血流量以动情后期最大,间情期仍维持在较高水平,动情期最小。动情后期和间情期与动情期比较均有显著差异(分别为p<0.01和P<0.05)。输卵管血流量动情期最大,动情前期最小,两期血流量的差异也有显著性(p<0.05)。由此表明,卵巢、子宫和输卵管血流量有明显的周期性波动。血流量的多寡与其生理机能状态和性激素的变化有关。  相似文献

The eye of Rhinomugil corsula has a duplex retina differentiated into dorsal and ventral halves, with the ventral retina 116·4 μm thicker than the dorsal retina. The rods of the ventral retina are relatively longer, with longer outer segments. The nuclei of the outer nuclear layer of the dorsal and ventral halves are in four and six to seven rows respectively. The rod outer segment bears a single incision. The mitochondria of cone and rod inner segments has a vitreal-scleral gradient. Single and double cones are present in both halves, with triple cones in the dorsal half only. The outer segments of double cones are equal and united. The single cones have two connecting cilia. The cone cells are arranged in a square mosaic with four double cones and five single cones to each unit in the dorsal half, and in a rhombic pattern in the ventral half.  相似文献

Summary The nitrification rate in the rhizosphere of Suaeda and Arthrocnemum plants growing in saline soils, as affected by microbial populations, temperature, pH, and organic matter, was examined in the field throughout the year. The genera Nitrosomonas and Nitrobacter were most common in the rhizosphere soil. The bacterial counts in the rhizosphere of both plants fluctuated during the study period, reaching peak values during February–March and in August. The nitrate concentration in the rhizosphere soil could be related with the observed increase in the numbers of ammonium-oxidizers and nitrite-oxidizers in the latter part of the study period. The pH of the rhizosphere soils did not have any influence on the nitrification rate at the values measured. The rhizosphere organic content varied between 1.8 and 4% (w/w), showing the continuous availability of organic matter in the soil. The seasonal changes in bacterial populations in the rhizospheres of both plants was described as the result of the combination of several factors.  相似文献
