  pylori
Comparative Analysis of Proteome Maps of Helicobacter pylori Clinical Isolates
      
The gram-negative bacterium Helicobacter pylori is found in human gastric mucosa.
      
pylori infection is associated with chronic gastritis, gastric and duodenal ulcers, and malignant neoplasms.
      
pylori clinical isolates derived from patients of two Russian regions (Moscow/Moscow Region and Novosibirsk) were obtained using 2D-electrophoresis and MALDI-TOF-mass-spectrometry.
      
pylori proteins and the level of their expression have been evaluated.

  pylorus
Heterogenous distribution of peptide-containing nerve fibres within the circular muscle layer of the human pylorus
      
The narrow region of the circular muscle layer bordering the submucosa in the pylorus contained a rich supply of VIP, SP, ENK and CGRP immunoreactive fibres; VIP fibres were most prominent with less SP and ENK fibres and moderate amounts of CGRP.
      
In the acute situation, intravenous erythromycin may alleviate gastroparesis, but probably exerts little beneficial effect beyond the pylorus; parenteral metoclopramide may be tried, but, here again, convincing evidence of efficacy is lacking.
      
In patients for whom all medical therapy fails, other options that are tried at experienced centers include the injection of botulinum toxin into the pylorus, placement of a feeding jejunostomy, and/or placement of a gastric electrical stimulator.
      
Surgical resection in the form of pylorus-preserving pancreaticoduodenectomy remains the optimal solution in the attempt to clarify the diagnosis and offer treatment with low complication rates.

(3)pectoral fin rays. (4) pyloric caeca. (5) the vertebrae. (6) fused pre-caudalhaemal spines. (7) post-cranial vertibrae with multiple neural spines. (8) de-gree of completeness of second anal pterygiophore. (9) the borny tubercle. (10)the parasites in abdominal cavity, and (11) the shape of the swim-bladder.Altogether 2232 samples in 24 lots were collected for ananalyses from theYellow Sea and Pohai, the East China Sea, the South China Sea, and the Gulfof Tongking. In addition, two lots of mixed samples and three lots of larvae ofthe same-year class have also been analized. The results obtained during the studies demonstrated that the hairtails maybe grouped into five local races, viz., (1) the Yellow Sea-Pohai race. (2) therace of the East China Sea-Eastern coast of Kwantung. (3) race of Westerncoast of Kwantung. (4) the race of coastal waters of the Gulf of Tongking. (5)the race offshore waters of the Gulf of Tongking. It is noticed that the first two races differ considerably from the otherthe three (Table 7).

本文主要系采用生物测定学与解剖学相结合的方法,调查了中国近海带鱼的种族。调查项目包括鱼体测量、背鳍条数、胸鳍条数、幽门盲囊数、椎骨数、尾前愈合脉棘数、头后多髓棘椎骨数、第二臀担骨的完缺情况、骨瘤、腹腔寄生虫和鳔的形状等11项。三年调查期间,分析的样品共为24批,计2,232尾。其中渤海为3批,300尾,黄海为4批,382尾,东海为10批,1,128尾,南海为4批,265尾,北部湾为3批,157尾。大部分样品系随机取样采自产卵场,但也分析过两批越冬期的混合样品和3批同龄幼鱼样品。 根据11个项目调查结果的综合分析,中国近海的带鱼,可分为黄—渤海、东海—粤东、粤西、北部湾近岸、北部湾外海等五个种族。其中前二族与后三族差异更大,后三族鱼的共同特点是尾部均较短,幽门盲囊数及第二臀担骨的缺如程度远较前二族为高,鳔前端常呈螺旋形弯曲,然背鳍及尾前愈合脉棘数则远较前两族为低,成体一般都生有枕骨瘤和背、臀担骨癌。但五族鱼本身,无论在背鳍条数、幽门盲囊数、躯椎数、尾前愈合脉棘数和骨瘤等方面,亦各独自具有可供识别的一系列特点。各族鱼群的具体特征可参看表7。 带角是中国近海的一种主要经济鱼类。因...

As there is no significant difference in the main characteristics between the local populations of Brachymystax found in Heilongjiang, Xinjiang, Tumenjiang, Qinling and northern area of Hebei, all the populations are the same species of B.lenok. Nichols and Pope had reported that it was possible to find out the species of B.lenok in the northern area of Hebei and Rehe. In 1975, the author collected some specimens in upper reaches of Tanghe River, and carried out a ecolo gical study on the population of Saihanba...

分布在黑龙江、新疆、图门江、秦岭、河北北部的细鳞鱼,它们的主要性状如:侧线鳞数、鳃耙数、幽门盲囊数、鳍条数及斑点的大小等,差异不明显,均为Brachymystax lenok(Pallas)种。Nichol和Pope曾报导和记录过河北北部及热河地区可能有细鳞鱼的分布。1975年笔者从汤河上游采到了标本,并对塞罕坝的细鳞鱼进行了生态研究。

Brachymystax lenok (Pallas), a landlocked salmonid fish, is one of the most important commercial fishes in the Yalu River. Morphologically, its characteristics generally agree with the description of the same species reported from other river-systems; the numbers of pyloric caeca, gillrakers, and scales along the lateral line among different populations appear to have certain overlapping.

细鳞鱼是鸭绿江的重要经济鱼类。幽门垂数、鳃耙数及侧线鳞数与国内其他产地相比呈现明显交叉。支流十三道沟河口以上的5公里江段为主要产卵场。产卵期为4—5月,盛期4月末。成熟个体多数4龄,最小成熟雌鱼体长309毫米。体长285—438毫米,体重315—1098克的个体绝对怀卵量1629至3119(平均2194),与体长L的关系式N=9.54924 L-1297.3246,与体重W的关系式N=2.2207W+641.6345。卵径3.5—4.0毫米。水温5.3—9.0℃时,受精后625小时孵出。用鳞片测定年龄及生长。3龄鱼体长可达356毫米,5龄鱼体长一般为389毫米。体长与体重的关系式W_(?)=0.002486L~(2.9146),W_♀=0.004509L~(2.8978)。
