| colorectal schistosomiasis. endoscopic polypectomy. | the role of colonoscopic polypectomy for schistosomal polyps was studied. the results showed that, in spite of the large number of polyps, a total of 404 polyps were removed from 20 patients. the procedure is feasible with minimal complications. a marked reduction of rectal bleeding occurred in half the patients, and the remaining half had minimal symptoms. colonoscopic polypectomy gives equal results to colonic excision for schistosomal polyps. | 1983 | 6641458 |
| schistosoma mansoni, s. japonicum, s. haematobium: glycogen content and glucose uptake in parasites from fasted and control hosts. | the glycogen content of male and female schistosoma mansoni has been measured in flukes from normally fed hosts and those from fasted hosts. in infections from both the mouse and the hamster, a significant reduction in schistosomal glycogen of males is seen hours after food is withdrawn from the host. reductions in protein content of the schistosomes were only observed in hamster infections fasted at least 72 hr. the livers of infected mice not only decrease in size during fasting, but there is ... | 1983 | 6641897 |
| [bacterio-parasitic interactions. enterobacteria and schistosomes (salmonella - schistosome association)]. | the description of a case imported from chad of an association of salmonella typhi - schistosoma haematobium and, in this connection, a new revised general account. the association salmonella-schistomas is wide-spread. it corresponds to a salmonello - schistosomo - micro - association by the fixation of precise bacteria in the case of a bacteriemia on the cutaneous surface of male schistosomes in clearly defined places. these salmonella constitute a permanent antigenic solicitation and they are ... | 1983 | 6645880 |
| urinary schistosomiasis in the sahelian region of the senegal river basin. | two dams are projected for the senegal river, west africa, for hydroelectric power, anti-salt intrusion and for provision of a dependable supply of freshwater year-round. this study was to ascertain the geographic distribution of schistosomiasis, its snail hosts and the potential transmission sites before the construction of the two dams. no intestinal schistosomiasis was found in the area investigated, the sahelian region. villages in the delta, as well as those situated by the senegal river in ... | 1983 | 6649050 |
| immunodiagnosis of schistosomiasis haematobium and schistosomiasis mansoni in man. application of crude extracts from adult worms and cercariae in the iha and the elisa. | the antibody responses of patients infected with s. haematobium or s. mansoni were investigated in an indirect hemagglutination test (iha) and an enzyme linked immunosorbent assay (elisa) using crude extracts of cercariae and adult worms of s. haematobium and s. mansoni, and of adult worms of s. japonicum. patients were africans from endemic areas, as well as europeans who had acquired their infection relatively recently. although the iha showed a similar pattern of antibody responses as the eli ... | 1983 | 6649986 |

| hepatic fibrosis in schistosoma haematobium-infected mice. | swiss mice were exposed subcutaneously to 270 to 500 schistosoma haematobium cercariae and killed 13 to 52 weeks later. less than 10% of applied cercariae were recovered as worms, and the rate of oviposition by adult worm pairs was generally low. however, the adult worms survived well, the females contained an average of 56 eggs one year after infection, and numerous mature eggs were present in the tissues. all worms were located in the portal venous system. s. haematobium eggs in the liver elic ... | 1983 | 6659047 |
| treatment with praziquantel in a patient with schistosomiasis and chronic renal failure. | the pharmacokinetics of praziquantel in a uraemic patient, infected with schistosoma haematobium, undergoing haemodialysis, was studied by repeated analyses of serum, urine and dialysis fluid. the results indicate the possibility of treating advanced cases of infection with s. haematobium with the normally recommended doses. | 1983 | 6659048 |
| day-to-day variation and circadian rhythm of egg excretion in urinary schistosomiasis in the sudan. | the daily variation of urinary excretion of schistosoma haematobium and schistosoma mansoni ova was assessed in a group of 24 sudanese schoolboys using the filtration trypan blue staining technique. an intra-class correlation coefficient of r = 0.88 indicated a surprisingly low daily variation of excretion of s. haematobium ova. all patients with a median egg output of at least 100 ova per 10 ml also voided s. mansoni ova in the urine. the daily variation of s. mansoni ova was slightly greater t ... | 1983 | 6660966 |

| identification of species-specific and gender-specific proteins and glycoproteins of three human schistosomes. | species-specific and gender-specific polypeptides of schistosoma haematobium, schistosoma japonicum, and schistosoma mansoni have been identified. proteins of these schistosomes were metabolically labeled in vitro with 35s-methionine and their total proteins, concanavalin-a binding glycoproteins, released (shed or secreted) proteins, and released glycoproteins compared by two-dimensional polyacrylamide electrophoresis. many of the released proteins were glycosylated, and most of the synthesized ... | 1983 | 6674449 |
| identification of sex of schistosome larval stages. | sex of schistosoma mansoni cercariae was identified by a c-banding technique; interphase nuclei of females exhibited w-chromatin (heterochromatin of the w chromosome) whereas those of males did not. similar sexual dimorphism was also shown in nuclei of s. mansoni miracidia, sporocysts, and adult worms. cercariae of the following schistosomes could not be sexed by examination of nuclei after the c-band technique: s. japonicum, s. haematobium, and schistosomatium douthitti . the method presented w ... | 1983 | 6674459 |

| the prepatent period and cercarial production of schistosoma haematobium in bulinus truncatus (egyptian field strains) at different constant temperatures. | the developmental time of schistosoma haematobium in bulinus truncatus snails (field strains) was determined in the laboratory at different constant temperatures between 18 and 32 degrees c. the basic relationship between the length of the minimum prepatent period (y, in days) and the temperature (x, in degree c) is given by the hyperbolic formula y = 295/(x-15.3), 15.3 being the theoretical "developmental null point" and 295 the constant time-temperature product. the shortest prepatency was 17- ... | 1984 | 6695537 |
| urinary calculus in zambia: its incidence and relationship to schistosoma haematobium infection and vesicovaginal fistula. | radiological, cystoscopic and histological observations were made on 41 cases of urinary stones in a hospital in zambia. the results of biochemical analysis of 31 of these stones are presented. the possible role of schistosoma haematobium in the causation of urinary stones has been analysed; associated schistosomiasis was diagnosed in 17 cases (41.4%). it is concluded that there is no significant causal association between the two disorders and urolithiasis is an uncommon disease in zambians. | 1984 | 6697105 |
| field studies on bulinus senegalensis muller and the transmission of schistosoma haematobium infection in a gambian community. | seasonal changes in populations of bulinus senegalensis were studied in temporary pools on the senegambian plateau. the first snails to appear had survived aestivation and had a mean height of 3 mm. thereafter two patterns of change in snail numbers and size were observed probably related to differences between pools in snail mortality rates. the prevalence of patent schistosome infections appeared to be related to the inferred differences in snail mortality rates. the prevalence and intensity o ... | 1984 | 6710598 |
