不同种类的我国淡水鲤科鱼类、不同鱼龄、不同水体以及短期饥饿、惊扰及网箱饲养对血清转氨酶活性没有影响,但水温升高或溶氧低于1ppm会使鱼血清谷草转氨酶活性升高

Results The patients were predominently female teenagers with a history of gradual onset of bilateral hearing loss, pure tone audiometry revealed symmetric ascending audiograms with moderate hearing loss at frequencies below 1 kHz, but relatively normal hearing at 2 kHz and above. Speech reception thresholds were between 40 to 85 dB HL, discrimination score was from 29% to 68%. Stapedial reflex, auditory brainstem response and compound action potentials were absent or threshold elevated disproportionately to the pure tone threshold. All of the patients had normal cochlear microphonics and robust spontaneously and transiently evoked otoacoustic emissions, the TEOAE showed no contralateral suppression effects as seen in normal subjects.

结果 该病多在青春期后起病,女性较多发,表现为渐进性双耳对称性听力下降,纯音听力以低频损失为主,语言接受阈升高,分辨率下降,镫骨肌反射及ABR引不出或阈值明显升高与纯音听力不成比例,耳蜗微音器电位正常,听神经动作电位引不出,耳声发射波幅高、时程长且不为对侧声刺激所抑制。

In transverse section, from migmatite →mylonitized migmatite →ultramylonite, phillite mylonite, the contents of Au, Ag, As, S, Cu, Bi, Se and W increase, the ratios of Au/Ag, S/Se and Cu/.

在矿床垂深剖面Au及伴生微量元素Bi、Se和S具有自上而下升高的趋势;Ag和W自160m至0m则下降,Au/Ag、S/Se和Bi/Au比值自上而下升高,这可以作为矿体延深评价及找矿地球化学的指示剂。

The dynamical modulus of elasticity decreases with the increasing of temperature, and increases lightly with the increasing of loading frequency.

研究表明:滞后能耗随温度的升高而增大,随填料比例增大而略有下降;动态弹性模量随温度的升高而减小,随频率的增加而略有增大。

With the temperature and strain increasing, modulus of elasticity of steel gradually decreases.

结果表明,钢材的应力-应变曲线随温度升高,应力变小而应变增大,曲线斜率即弹性模量随温度升高和应变增大而趋于零。

The results showed that increasing zero-valent iron dose and temperature can enhance the removal rate of molybdate; the maximum removal rate was 96% at pH = 2.0, which decreased with the increase of pH value.

结果表明,随着零价铁投加量的增大和温度的升高,钼的去除率有所提高;在pH=2.0时零价铁对钼的去除率最高(96%),随着pH值的升高,钼的去除率降低。

On hyperlipemia show that the pigment could reduce the serum TC, TG, LDL-C concentrations, increase serum and liver T-AOC, GSH-PX activities, decrease liver MDA content significantly (P<0.05). The pigment of Lycium ruthenicum Murr. can inhibit the increase of blood lipids level and increase antioxidant activity in mice with hyperlipemia.

高脂血症预防实验显示,PLR可降低小鼠血清总TC和TG、LDL-C的含量,升高血清和肝组织T-AOC、GSH-PX活性,显著降低肝组织MDA含量(P<0.05),说明黑果枸杞色素对高脂血症小鼠血脂水平升高和脂质过氧化均有一定抑制作用。

Meanwhile, ABA inhibited the activities of phospho-glucose isomerase and invertase, increased the activities of phospho glucose mutase and starch phosphorylase, indicating that ABA was the most effective factor in saccharide metabolism and to the related enzyme activities on the 1st to 7th days after treatments.

推测非还原糖含量的升高可能是ABA促进其积累和抑制转化酶活性所致,淀粉含量升高的原因可能是ABA增强了淀粉磷酸化酶的活性,果糖与葡萄糖比值的降低可能是由于ABA对PGI活性抑制和对PGM活性促进的双重影响。

The results showed that water content decreased first, then increased in the gastrula stage of embryonic development, reached the highest content at the second phrase larvae stage and then began to decrease from the third phase larva stage. The content of lipid in the dry weight increased with the embryonic development stages, but decreased at intramembranous nauplius stage, the second phase larva, and the infant stage of larvae development. The rate of lipid in wet weight decreased and the content of C20:4w6、20:5w3 and C22: 6w3 decreased.

结果显示,黑斑口虾蛄在胚胎和幼体的发育过程中,水的体积分数先降低,至原肠胚期开始升高,到第二相幼体期达到最高,之后又有所回落;脂类占组织干重的比率呈升高趋势,但分别在膜内无节幼体、第二相幼体和仔虾蛄期略有降低;脂类占组织湿重的比率呈降低趋势;花生四烯酸、EPA和DHA的体积分数都呈降低趋势。

Across the altitudinal gradient, a total of 12635 individuals belonging to 6 phyla, 15 classes and 33 orders were collected. With increasing altitude, the density of soil fauna decreased, but the group number was less affected. There was a higher co-occurrence of soil faunal communities along the altitudinal gradient, and Nematoda, Acarina, and Collembola were the dominant groups. Below the altitude 370 m, the Shannon-Wiener index, Pielou index, and Margalef abundance index increased with increasing altitude; while above the altitude 370 m, the Shannon-Wiener index and Pielou index decreased but the abundance index increased after an initial slight decrease.

结果表明:土壤动物密度随海拔升高而下降,类群数受海拔影响较小,各海拔群落的共有度较高,优势类群基本均为线虫、蜱螨目和弹尾目;Shannon-Wiener指数、Pielou均匀度指数及Margalef丰富度指数仅在海拔370 m以下随海拔升高而增加,而在海拔370 m以上,Shannon-Wiener指数与Pielou均匀度指数下降,丰富度指数在略有下降后再次上升。
