“…Functional importance of enzyme activity in hypodermal cells has been discussed by many authors. It may work for transport of substance through the cuticle or production and maintenance of the cuticle (Dusanic, 1959;Sood, 1977). Recently Yanagisawa (1979b, 1980a, b, c) reported that gastro-intestinal nematodes showed high enzymic activity in the intestine and low in the body wall, and that tissue nematodes including filarial worms showed high activity in the body wall.…”

Histochemical localization of acid phosphatase was reported on the microfilariae isolated from the peripheral blood of the dog and their developing larvae in mosquitoes in comparison with the localization in those from the jird's peritoneal cavity and their larvae. Whole body of microfilariae stained red with dark red excretory vesicle and anal vesicle. The sheaths were negative in those from the dog, while positive in most microfilariae from the jird. During the first two days after the intake unstained larvae were frequently found in the mosquitoes fed jird microfilariae in contrast to those fed on the dog. From the third day on, positive developing intestine was observed. After the first molt the esophagus appeared as a red double line. On the 7th day strong activity was found at the esophagus, intestine, developing anus and amphids, while the nerve ring was negative. Positive reaction was detected at the hypodermis and anus of infective larvae.

“…Hoskin & Cheng (1974), McManus & James (1975a, 1975b, and Smyth & Halton (1983) report that sporocysts of other genera also can actively transport monosaccharides from the tissues of their snail intermediate hosts through their teguments. In addition, a number of investigators have documented the presence of nonspecific phosphatase activity associated with the extensive microvillar surface of a number of sporocysts (Dusanic, 1959;Dike & Read, 1971 ;Koie, 1971 ;Krupa & Bogitsh, 1972) . Membrane-associated nonspecific phosphatase activity has been observed in tissues active in carbohydrate transport .…”

The outer covering of digenetic trematodes undergoes a number of changes in the course of the life cycle in adaptation to parasitism and to the host-seeking requirements of the various stages . Using Schistosoma mansoni as a model, I review morphological, physiological, and cytochemical features of the coverings of miracidia, sporocysts, cercariae, and adults. Such features should be used with caution in evaluating phylogenetic relationships of any flatworms since the environment is itself a powerful determinant .

“…Isto foi confirmado no experimento de digestão do tegumento com fosfolipase C. Os ortólogos da enzima de humano e outros mamíferos comparados, também possuem sinal para âncora de GPI, o qual revela que a estrutura está conservada. O tamanho predito de ~65 kDa do monômero glicosilado (BALLEN et al, 2002;CESARI;EVANS, 1981; fato dos ovos expressarem altos níveis de proteína e mostrarem pouca atividade enzimática na superfície seria devido provavelmente ao fato da maioria da atividade estar localizada dentro dos ovos (DUSANIC, 1959).…”

“…O soro anti-rSmAP reconheceu, com particular intensidade, as glândulas vitelinas na seção de fêmea, sugerindo uma função importante da SmAP em alguns dos processos associados com a produção dos ovos, tais como síntese de proteínas e ácidos nucléicos (DUSANIC, 1959). As imunolocalizações da SmAP nos parasitas inteiros, revelaram um padrão de expressão difuso no estágio de esquistossômulo de 7 dias, torna-se muito homogênea no esquistossômulo de 21 dias.…”
