During a survey of helminth parasites of freshwater fishes, from the Min River in Fooehow, a number of specimens of trematodes belonging to the genus Eumasenia Sri-vastava, 1951 were secured from the stomach and intestine of Clarias fuscus (Lace-pede). They belong to a species new to science and the diagnosis is briefly given as follows:Maseniidae; Body small, 1.04-1.68 mm. long by 0.32-0.63 mm. in maximum diameter, at the level of testes. Cuticle armed with spines more prominent anteriorly and absent in posterior...

During a survey of helminth parasites of freshwater fishes, from the Min River in Fooehow, a number of specimens of trematodes belonging to the genus Eumasenia Sri-vastava, 1951 were secured from the stomach and intestine of Clarias fuscus (Lace-pede). They belong to a species new to science and the diagnosis is briefly given as follows:Maseniidae; Body small, 1.04-1.68 mm. long by 0.32-0.63 mm. in maximum diameter, at the level of testes. Cuticle armed with spines more prominent anteriorly and absent in posterior third of tody. Oral sucker funnel-shaped, 0.141-0.173 × 0.135-0.189 mm., with two, middorsally interrupted, alternating crowns of spines. 25-32 circumoral spines in each row. Circumoral spines of the first row, measuring 0.017-0,025 mm. long by 0.004-0.008 mm. wide; those of the second row, measuring 0.017-0.025 mm. long by 0.003-0.008 mm. wide. Ventral sucker, 0.141-0.169 × 0.137-0,176 mm., situated middle third of body. Prepharynx, 0.022-0.064 mm. long; pharynx 0.034-0.064 × 0.043-0.073 mm.; oesophagus, 0.086-0.111 mm. long. Intestinal caeca short, extending to level of the middle region of anterior testis. Testes oval, one obliquely behind the other, intercecal, in the third quarter of body. Anterior testis measures 0.078-0.134 mm. long by 0.124-0.129 mm. wide; posterior testis 0.060-0.141 mm. by 0.120-0.236 mm. Cirrus pouch very long measuring 0.677-0.96 mm. long by 0.071-0.099 mm. in basal diameter, enclosing bipartite seminal vesicle, prostate complex and ejaculatory-duct. Pars prostatica without the lateral diverticulum.Common genital pore dorsal to oral sucker just at the dorsal gap in crown of circumoral spines. Ovary 0.076-0.179 × 0.083-0.150 mm., lies slightly submedian, obliqualy to right, between acetabulum and anterior testis. Receptaculum seminis large, 0.064-0.159 × 0.042-0.107 mm., between testes and ovary. Laurer's canal present, Vitellaria follicular, extending in lateral fields from acetabular level to an- terior testicular zone. Uterus with descending and ascending limbs almost occupying whole posttesticular area. Excretory vesicle saccular reaching to posterior margin of posterior testis. Eggs numerous, operculate, 0.022-0.031* 0.015-0.019 mm.Eumasenis fukienensis is separated from its closely related species E. moraddba-densis Srivastava, 1951 and E. bangweulensis Beverly-Burton, 1962 by the size of body, size and number of circumoral spines, the length of prepharynx and oesophagus, and by the absence of a kteral prostatic diverticulum and in having a sac-shaped excretory vesicle.The life cycle of Eumasenia fukienensis was established experimentally in the laboratory and all stages described. Eggs are fully embryonated when laid, swallowed by the molluscan hosts, Hippeutis canton Benson, Gyraulus convexiusculus Hutton, or Segmentina hemisphaerula (Benson). The miracidia penetrate into intestinal wall and transform into small embryos with germinal cells. Mother and daughter sporocysts developed outside the intestine and in the digestive gland of the snails. The latter gives rise to cercariae which emerged from snails 24 days after the eggs had been eaten. Cercariae encysted in the mature daughter sporocysts or penetrated and encysted in the tissue of the same intermediate host or other snails such as Sphaerium lacustre (Muller), which live together with Hippeutis cantori Benson. Me-tacercariae when fed to Clarias fuscus (Lacepede), developed into premature adult in the small intestine in 10 days.Based on the studies of the life cycle of E. fuUenensis, it is demonstrated that Family Maseniidae Yamaguti, 1954 is closely related to Family Plagiorchiidae Luhe, 1091. The phylogenetic relationship of the two families is discussed.

1.本文详细描述了福州地区胡子鲶肠管中极常见的一种真马生尼亚吸虫的形态构造,由于福建标本在虫体的大小,围口棘圈中棘的数目、大小,腹吸盘位置,前咽及食道的长度,肠管盲端到达的位置,卵巢、睾丸所在的位置,以及其相关的大小,前列腺管基部的构造,以及排泄囊的形状等,和文献上已记述的虫种差别很大。因此我们为其定名为福建真马生尼亚吸虫Eumasenia fukienensis sp.nov.。 2.本文详细描述了本种吸虫虫卵、毛蚴以及在三种扁螺类:凸旋螺Gyraulus conve-xiusculus Hutton;肯氏圆扁螺Hippeutis cantori Benson和半球隔扁螺Segmentina hemis-phaerula (Benson)体内发育的二代胞蚴、尾蚴以及囊蚴等各幼虫期的形态。 3.本文对本种吸虫在系统发生上和斜睾科吸虫的亲缘关系进行讨论。

PSA as one of the most important tumor marker. is used to help diagnosis and monitor the therapeutic efficacy of prostate cancer.

前列腺特异性抗原 (PSA)是一种单链糖蛋白 ,它由前列腺上皮细胞产生 ,分泌至前列腺管 ,因此精液中PSA含量很高 ,而正常人血清中含量很少。癌变时 ,患者 PSA在血中的浓度升高。近年来 ,人们对 PSA的生物学特征、检测方法、临床应用进行了大量的研究 ,取得了很大进展。PSA已成为最具有临床价值的肿瘤标志物之一 ,被应用于前列腺癌的临床诊断和监测。
