A Study on POD and EST Isozyme of Different Strains of Fusarium oxysporum from Different Crops

利用聚丙烯酰胺凝胶电泳测定了来自不同寄主枯萎病原菌尖孢镰刀菌过氧化物酶同工酶(POD)和酯酶同工酶(EST).结果表明,过氧化物酶同工酶共有3条主酶带,其迁移率分别为:Rf=0.08,Rf=0.20和Rf=0.4.但不同寄主的尖孢镰刀菌POD同工酶存在着明显的差别,来源于花生的尖孢镰刀菌只有2条POD同工酶酶带,其迁移率为:Rf=0.20和Rf=0.08;来源于甜瓜的尖孢镰刀菌只有1条POD同工酶酶带,其迁移率为:Rf=0.20;来源于不同寄主的镰刀菌的EST同工酶谱之间也存在着较大的差别.来源于黄瓜、甜瓜和西瓜的镰刀菌的EST酶谱较为相似,都具有Rf=0.018,Rf=0.114和Rf=1.000的3条酶带,其它寄主来源的镰刀菌的EST酶谱间互相则存在着很大的差别.但这些菌株基本上都存在着Rf为0.018和1.000的2条酯酶同工酶酶带.The peroxidase (POD) and esterase (EST) isozyme of different Fusarium oxysporum from different crops were analyzed by polyarcylamide gel eletrophoresis.The results showed that there were 3 main POD isozme bands;the relative migration rates were 0.08,0.24,and 0.4.The strain from the earthnut had only 2 POD isozyme bands and their relative migration rates were 0.20 and 0.08.The strain from melon had only 1 POD isozyme bands and its relative migration rate was 0.20.There were many differences found in esterase isozyme of the different strains of F.oxysporum,in whixh the main isozyme bands were similar in cucumber,melon and watermelon and their relative migration rates were 0.018,0.114,1.000,and that of the F.oxysporum from the other crops was much different.But they all had the main EST isozme bands whose relative migration rates were 0.018 and 1.000.国家863计划项目(2002AA244031 2);; 福建省计委项目(闽计农经[2002]48号)资

狮弓蛔线虫（TOXASCARISLEONINA）的形态学研究

本文对狮弓蛔虫（Toxascaris leonina）虫体及其虫卵进行了全面而系统的形态学研究。本项研究使用饱和盐水漂浮法对哈尔滨动物园猫科动物进行粪检,用盐酸左旋咪唑进行驱虫,对获得的虫体及其虫卵分别利用光学显微镜和电子显微镜进行了形态学研究。在国内首次利用电子扫描显微镜和电子透射显微镜对获得的狮弓蛔虫虫体及虫卵进行了形态学的观察。发现了一些过去未知的结构:（1）卵黄膜的超显微结构（2）细齿形态与排列方式（3）雄虫的尾感器（4）雄虫肛门前缘的乳头状突起（5）唇尖部的口孔与唇片的连接方式和部位（6）生殖乳突、生殖孔的扫描立体形

吡喹酮驱除兰狐和银黑狐华支睾吸虫试验

华支睾吸虫病,为人兽共患寄生虫病,同时也严重侵袭兰狐和银黑狐。华支睾吸虫病不仅可以造成狐狸消瘦、拒食、全身黄染、腹泻等消化机能紊乱,幼狐生长发育受阻,母狐的繁殖能力明显下降,而且常常导致狐狸死亡。目前,国内外,常用丙硫咪唑和吡喹酮治疗人及家畜的华支睾吸虫病。关于狐狸华支睾吸虫病的治疗还未见报道。1989年11月,我们首次选用国产吡喹酮片剂,对患华支睾吸虫病的狐狸进行了驱虫试验,取得了较好的效果。同时,做了扩大试验,随访了半年,证实了该药疗效的确实性。材料与方法一、试验药物吡喹酮,系南京制药厂生产的白色片剂,每片含量为200mg,批号880308。二、试验动物从哈尔滨某野生饲养场选出严重感染华支睾吸虫,症状明显的,体重约5kg的

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
