The present studies investigate the induced effects of two pesticides lambda cyhalothrin (pyrethroid) and monocrotophos (organophosphate) on Rana cyanophlyctis (common skittering frog). Two different concentrations i.e. 0.1 and 1% were used and cholinesterase activity was observed in liver, kidney and brain of these frogs. It was decreased upto 34.6 and 46.3% in liver, 25.08 and 57.1% in kidney and 31.64 and 50.7% in brain under the effect of lambda cyhalothrin. In the case of monocrotophos treatment, cholinesterase decreased upto 37.7 and 57.7% in liver, 57.5 and 67.5% in kidney and 47.6 and 65.9% in brain, respectively.
本文研究了氯氰菊酯(拟除虫菊酯)和有机磷磷(有机磷磷)两种农药对蓝喉蛙(Rana cyanophlyctis)的诱导作用。分别用0.1%和1%浓度的胆碱酯酶,观察肝、肾和脑胆碱酯酶活性。在溴氰菊酯的作用下,肝脏、肾脏和大脑的致死率分别下降了34.6%、46.3%、25.08、57.1%和31.64、50.7%。单氯磷组胆碱酯酶在肝脏、肾脏和脑组织分别下降37.7%和57.7%、57.5和67.5%和47.6%和65.9%。

Effects of the settlement density of germlings and canopy on settled germlings of Fucus serratus were investigated on the rocky shore of the Isle of Man. The survival of transplanted germlings was mainly determined by parent canopy rather than by initial settlement density of germlings. However, germling growth was greater at low density than at high density and enhanced by canopy removal. Recruitment by natural propagules was stimulated at high settlement density and maximal recruits occurred on caged slides under the canopy. On the experimental slides, tiny snails and sedimentation were found. The number of snails was positively related with the settlement density of germlings indicating that they fed the germlings. Sedimentation and snail number were greater with canopy removal treatments than in canopy intact ones. These indicate that canopy sweeping gives benefits to germlings by removing sediment from substrata and protecting them from herbivores. In conclusion, the survival of settled F. serratus germlings is mainly determined by canopy sweeping and their growth is retarded in the presence of a canopy and at high settlement density.
在马恩岛的岩石岸边,研究了菌种沉降密度和冠层对黑角藻(Fucus serratus)菌种沉降的影响。移栽苗的成活率主要由亲本冠层决定,而不是由苗的初始沉降密度决定。低密度条件下幼苗的生长大于高密度条件下幼苗的生长,且冠层去除有利于幼苗的生长。在高沉降密度条件下,自然繁殖体的招募受到刺激,最大的招募发生在冠层下的笼状载玻片上。在实验载玻片上发现了微小的蜗牛和沉淀物。钉螺数量与苗种沉降密度呈正相关,表明钉螺以苗种为食。去除冠层处理比保留冠层处理沉降量和钉螺数量大。这些表明,林冠清扫通过清除底层的沉积物和保护它们免受食草动物的侵害,对胚芽有好处。综上所述,有冠层存在和高沉降密度时,沉降的锯齿木孢子的成活主要受冠层清扫的影响,其生长受到抑制。

Vertebrates with different habitats have different proportions of visual cells, with the rod cells responding to scotopic vision and the cone cells responding to photopic and color vision in their retinas. The present work studied whether the kinds and arrangement patterns of the cone cells and interlocking morphology of the lens were related to the kind of preys and habitats in the genus Zacco. The retinas were observed by a light microscopy using H‐E staining method and the interlocking formula of the lens fibers were investigated by a scanning electron microscopy. The interlocking formula of the lens fibers of Z. temmincki is an “anchor and socket” connection, and that of Z. platypus is a “ball and socket” connection. The cone cells of Z. platypus and Z. temmincki constituted compacted mosaic patterns of row type. Away from the center, the double and single cone cells gradually increased in diameter. Zacco temmincki had identical double cone cells and Z. platypus had non‐identical double and single cone cells. The eyes of Z. temmincki feeding on a moving aquatic insects in relative limpid water and swift current of mid and upper stream have better resolution than that of Z. platypus feeding on mainly adhesive algae and some aquatic insects in slightly turbid water of mid stream.
不同栖息地脊椎动物的视网膜视细胞比例不同,视杆细胞响应暗视,视锥细胞响应光视和色觉。本文研究了锥细胞的种类和排列模式以及晶状体的连锁形态是否与Zacco属的猎物种类和生境有关。用H - E染色法在光镜下观察视网膜,用扫描电镜研究晶状体纤维的互锁公式。Z. temmincki的透镜纤维互锁公式为“锚与窝”连接,Z.鸭嘴兽的透镜纤维互锁公式为“球与窝”连接。鸭嘴兽的锥体细胞呈致密的行型镶嵌图案。在远离中心的地方,双锥细胞和单锥细胞直径逐渐增大。鸭嘴兽的双锥细胞和鸭嘴兽的双锥细胞不相同。在相对清澈的水体和湍急的中上游水流中,以游动的水生昆虫为食的鸭嘴兽的眼睛分辨率优于以黏着藻类为主的鸭嘴兽和以部分水生昆虫为食的中游微浑浊的鸭嘴兽。

Abnormalities in fibrinolysis system is associated with risk of hypertension. In this report, the Alu repeat insertion/deletion (I/D) polymorphism of tissue plasminogen activator (t‐PA) and the Hind III RFLP of plasminogen activator inhibitor‐1 (PAI‐1) genes were investigated in 115 normotensives and 83 patients with hypertension, and their association with anthropometrical data and plasma biochemical parameters were analyzed. There were no significant differences in the gene frequencies of the two candidate genes between normotensives and hypertensives, respectively. Our results indicate lack of associations between the two polymorphisms in t‐PA and PAI‐1 genes and risk of hypertension in the population under study. However, the Hind III RFLP of PAI‐1 gene was significantly associated with plasma glucose level, suggesting its role in glucose metabolism. It needs to be tested whether this RFLP of PAI‐1 gene is associated with insulin resistance syndrome or non‐insulin dependent diabetes mellitus (NIDDM) in the Korean population.
纤溶系统异常与高血压风险相关。本文对115例血压正常者和83例高血压患者的组织型纤溶酶原激活物(t‐PA) Alu重复插入/缺失(I/D)多态性和纤溶酶原激活物抑制剂- 1 (PAI‐1)Hind III RFLP基因进行了研究,并分析了它们与人体测量数据和血浆生化参数的相关性。在正常血压和高血压患者之间,这两个候选基因的基因频率分别没有显著差异。我们的研究结果表明,在研究人群中,t - PA和PAI - 1基因的两种多态性与高血压风险之间缺乏相关性。然而,PAI‐1基因Hind III RFLP与血浆葡萄糖水平显著相关,提示其在葡萄糖代谢中起作用。在韩国人群中,PAI - 1基因的RFLP是否与胰岛素抵抗综合征或非胰岛素依赖型糖尿病(NIDDM)相关,需要进一步研究。

Immunoassays have become indispensable tools and achieved great importance in scientific and medical research. However, typical immunoassays are time‐consuming and use complex, multi‐step procedures. In this study, we introduce a new immunoassay system for the quantification of several analytes at a time without any washing steps. It is comprised of a detector solution with fluorescence‐labeled antibodies and a test strip with immobilized capture antibodies. Using a micro‐array scanner, the antigen‐anti body complex was quantitatively determined by measuring the intensities of fluorescence on the capture lines or dots of nitrocellulose membrane. This method demonstrated its rapid quantitative determination of analytes without many processing steps as well as specific identification of multiple analytes in biological specimens.

We studied the nectar secretion of the Japanese Camellia (Camellia japonica L.), an evergreen tree and observed its floral visitors during the day. The mean volume of nectar secreted, during daylight (08:31 to 16:30 h) was 30.26 ± 18.29 ml (SD) (n = 27). During the late afternoon and overnight (16:31 to 08:30 following day), 100.54 ± 54.85 ml (n = 27) of nectar was secreted. Total volume measured when flowers were sampled once every two hours for an eight‐hour period was approximately one‐half the volume which was measured when the flowers were sampled only once after eight hours. The mean nectar volume secreted was 8.55 ± 8.3 ml (n = 30) between 08:31 to 10:30, 4.38 ± 6.1 ml (n = 30) between 10:31 to 12:30, 4.6 ± 5.4 ml (n = 30) between 12:31 to 14:30, and 4.02 ± 3.5 ml (n = 30) between 14:31 to 16:30 hours. During the day, Japanese Camellia flowers were principally visited by the Japanese white‐eye (Zosterops erythropleura erythropleura S.), a native bird, although insects and squirrels also visited to a lesser degree.
研究了常绿树种日本茶花(Camellia japonica L.)的花蜜分泌,并观察了其白天的访花情况。白天(08:31 ~ 16:30 h)平均分泌花蜜量为30.26±18.29 ml (SD) (n = 27)。在下午晚些时候和夜间(16:31 -次日08:30),分泌了100.54±54.85 ml (n = 27)的花蜜。当花在8小时内每两小时采样一次时,测量的总体积大约是8小时后只采样一次时测量的体积的一半。08:31 ~ 10:30平均分泌量为8.55±8.3 ml (n = 30), 10:31 ~ 12:30平均分泌量为4.38±6.1 ml (n = 30), 12:31 ~ 14:30平均分泌量为4.6±5.4 ml (n = 30), 14:31 ~ 16:30平均分泌量为4.02±3.5 ml (n = 30)。白天,日本白眼(Zosterops erythropleura erythropleura S.)(一种本地鸟类)主要光顾日本山茶花,尽管昆虫和松鼠也有较少程度的光顾。

Isolation and characterization of methyl jasmonate‐inducible genes in chinese cabbage 白菜茉莉酸甲酯诱导基因的分离与鉴定
Pub Date : 2003-01-01 DOI: 10.1080/12265071.2003.9647725

Methyl jasmonate (MeJA) is a signal molecule in the activation of defense responses in plants. In this study, we isolated 15 MeJA‐inducible genes by subtractive hybridization. These genes encode two myrosinase‐binding proteins, five lipase‐like proteins, a polygalacturonase inhibitor, a putative chlorophyll‐associated protein, a terpene synthase, a dehydroascorbate reductase, an ascorbate oxidase, a cysteine protease, an O‐methyltransferase, and an epithiospecifier protein. Northern analysis showed that most of the Chinese cabbage genes are barely expressed in healthy leaves, but are strongly induced by MeJA treatment. We also examined whether these MeJA‐inducible genes were activated by ethethon, BTH, and Pseudomonas syringae pv. tomato (Pst), a nonhost pathogen of Chinese cabbage. The results showed that none of the MeJA‐inducible genes was strongly induced by ethephon or by BTH. The genes encoding lipase‐like proteins and a myrosinase‐binding protein were weakly induced by Pst. Other MeJA‐inducible genes were not activated at all by the pathogen.
茉莉酸甲酯(MeJA)是植物防御反应激活的信号分子。在这项研究中,我们通过减法杂交分离了15个MeJA诱导基因。这些基因编码两种黑芥子酶结合蛋白、五种脂肪酶样蛋白、一种聚半乳糖醛酸酶抑制剂、一种推定的叶绿素相关蛋白、一种萜烯合成酶、一种脱氢抗坏血酸还原酶、一种抗坏血酸氧化酶、一种半胱氨酸蛋白酶、一种O -甲基转移酶和一种上皮指示物蛋白。Northern分析表明,大部分白菜基因在健康叶片中几乎不表达,但在MeJA处理下被强烈诱导。我们还研究了这些MeJA诱导基因是否被乙醚、BTH和丁香假单胞菌pv激活。大白菜的非寄主病原菌番茄(Pst)。结果表明,没有一个MeJA‐诱导基因被乙烯利或BTH强烈诱导。编码脂肪酶样蛋白和黑芥子酶结合蛋白的基因被Pst弱诱导。其他MeJA诱导基因未被病原体激活。

Two diastylid species, Dimorphostylis manazuruensis Gamô (1960) and Dimorphostylis longicauda Gamô (1962), are recorded as new to Korean cumacean fauna. The subadult male of D. longicauda is described for the first time. As a result, the genus Dimorphostylis found in Korean waters now consists of eight species.

Genetic relationship between Korean and Mongolian populations based on the Y chromosome DNA variation 基于Y染色体DNA变异的朝鲜族和蒙古族人群遗传关系

We analyzed seven Y chromosome binary markers (YAP, RPS4Y711, M9, M175, LINE1, SRY+465 and 47z) in samples from a total of 254 males from Koreans and two Mongolian ethnic groups (Buryat and Khalkh) to study the genetic relationship among these populations. We found eight distinct Y haplogroups constructed from the seven binary markers. Haplogroup DE‐YAP was present at extremely low frequencies (∼2%) in the Korean and Mongolian populations. This result is consistent with earlier reports that showed the YAP+ chromosomes to be highly polymorphic only in populations from Japan and Tibet in east Asia. The observed high frequency of haplogroup C‐RPS4Y711 in the Mongolian populations (∼40%) is concordant with recent findings, showing that the RPS4Y711‐T chromosomes were distributed at high frequencies in Siberian and Mongolian populations compared with most other populations from east Asia. Thus, the relatively moderate frequency of haplogroup C‐RPS4Y711 in Koreans (∼15%) can be seen as genetic evidence for probable interaction with Mongolian and/or Siberian populations. In contrast, the majority (∼75%) of modern Koreans studied here had high frequencies of Y chromosome lineages of haplogroup O‐M175 and additional haplogroups that define sublineage of O‐M175, which are most likely related with modern populations in China. In conclusion, our data on the Y chromosome haplogroup distribution may provide evidence for interaction between Korean and Mongolian populations, but Koreans tend to be much more related with those from southern‐to‐northern populations of China than to Mongolians in east Asia.
本文分析了254份朝鲜族和2个蒙古族(布里亚特族和喀尔喀族)男性的Y染色体双标记YAP、RPS4Y711、M9、M175、LINE1、SRY+465和47z的遗传关系。我们从7个二元标记中发现了8个不同的Y单倍群。单倍群DE - YAP在韩国和蒙古人群中出现的频率极低(约2%)。这一结果与先前的报道一致,即YAP+染色体仅在东亚的日本和西藏人群中高度多态性。单倍群C‐RPS4Y711在蒙古人群中的高频率(约40%)与最近的研究结果一致,表明与东亚大多数其他人群相比,RPS4Y711‐T染色体在西伯利亚和蒙古人群中的分布频率较高。因此,韩国人C‐RPS4Y711单倍群的相对中等频率(约15%)可以被视为可能与蒙古和/或西伯利亚人群相互作用的遗传证据。相比之下,这里研究的大多数现代韩国人(约75%)具有高频率的O - M175单倍群Y染色体谱系,以及定义O - M175亚谱系的其他单倍群,这些单倍群最有可能与中国现代人群相关。总之,我们关于Y染色体单倍群分布的数据可能为韩国人和蒙古人之间的相互作用提供了证据,但韩国人往往与中国南北向人群的关系比与东亚蒙古人的关系更密切。
