| 4-isothiocyanato-4'-nitrodiphenylamine (c 9333-go/cgp 4540), an anthelminthic with an unusual spectrum of activity against intestinal nematodes, filariae and schistosomes. | 4-isothiocyanato-4'-nitrodiphenylamine was found to possess activity against intestinal nematodes in mice, against schistosomes in various hosts including primates and against two filarial species in the mongolian jird. upon administration in a single oral dose it is equally effective against s. haematobium, s. mansoni and s. japonicum. | 1976 | 817928 |
| proliferative epithelial lesions of the urinary bladder in cynomolgus monkeys (macaca fascicularis) infected with schistosoma intercalatum. | five cynomolgus monkeys (macaca fascicularis) were infected with schistosoma intercalatum, a helminth that is morphologically similar to schistosoma haematobium. infections were readily established and remained active until the monkeys were sacrificed 21 to 84 weeks after exposure. although the schistosomes were located predominantly in mesenteric and hepatic portal venules, schistosome eggs were found in the bladders of 3 monkeys. nodules of atypical epithelial cells interpreted as superficiall ... | 1976 | 819136 |
| calcification of the bladder and papillary tumours of the bladder and ureters in gibbons (hylobates lar) infected with schistosoma haematobium (iran). | many species of nonhuman primates have been employed to find parasite-definitive host combinations which would allow for investigations on different aspects of schistosomiasis haematobia. gibbons (hylobates lar), exposed to moderate numbers of schistosoma haematobium cercariae, have demonstrated some of the basic features of schistosomiasis haematobia in man. calcification in schistosomiasis haematobia is variable. radiologically evident calcification of the bladder was noted in one gibbon. radi ... | 1975 | 820019 |

| the less familiar manifestations of schistosomiasis of the urinary tract. | one hundred and fifteen patients with schistosomiasis of the urinary tract were studied. sixty-five percent of the ureters showed striking deformities, including medial deviation, a straight lumbar course, and in the pelvic segment a bowed appearance with medial and cranial displacement at the vesico-ureteric junction. this appearance, which resembles a "cowhorn", is due to fiborsis the bladder trigone. stasis and dilation of the upper urinary tract were present in the absence of mechanical obst ... | 1977 | 831926 |
| studies on schistosomal rectal and colonic polyposis. | anatomic and digestion studies were done on rectal and colonic schistosomal polyps from 30 patients. results indicate that schistosomal colonic polyposis is principally due to high, localized egg burdens of schistosoma mansoni or s. haematobium resulting in damage to the muscularis mucosa of the colon. furthermore, atypically focal oviposition by s. mansoni is probably more important in genesis of rectocolonic polyposis than is schistosomiasis haematobium. | 1977 | 842787 |
| schistosomal polyposis of the urinary bladder. | anatomic, clinical, and digestion analyses were done on 18 human urinary bladder polyps from patients with schistosoma haematobium infections. variations in histologic pattern conformed to stages in progression of the disease; most were from active cases with significant egg burdens. the data suggest that polypoid lesions of active schistosomiasis may persist as polyps in the inactive stage if antecedent active infection was heavy. | 1977 | 842788 |
| schistosomal ulceration of the urinary bladder. | clinical, anatomic and digestion studies were done in 91 surgically treated cases of bladder ulceration in egyptian patients with urinary schistosomiasis. most patients were rural male farmers; their mean age was 29 years. symptoms were similar to uncomplicated urinary schistosomiasis except for suprapubic or perineal pain. two clinicopathologic entities were noted: 1) sloughing of polypoid patches in early active disease; and 2) chronic schistosomal ulceration of the bladder occurring at sites ... | 1977 | 842789 |
| surgical pathology of schistosomal obstructive uropathy: a clinicopathologic correlation. | schistosomal obstructive uropathy was studied by clinical, laboratory epidemiologic and pathologic analysis in 155 egyptian patients treated surgically. most patients were men; rural farmers or laborers. all had severe urinary schistosomiasis with heavy burdens of schistosoma haematobium eggs in their urinary tracts. schistosomal incomplete ureteral stenosis and schistosomal stenosis with ureterolithiasis were the most important obstructive lesions; these lesions were symmetrical and most freque ... | 1977 | 842790 |
| immunological studies in human schistosomiasis. ii. antibodies cytotoxic for schistosoma mansoni schistosomules. | complement dependent cytotoxic antibodies for schistosoma mansoni schistosomules were studied in a brazilian population. the sera of s. mansoni-infected patients gave a high percentage of cytotoxicity (63.4%) compared with sera from persons not infected (8.7%). the igg class and the specificity of these cytotoxic antibodies are defined. the index of lethality appeared to be independent of the titers of other specific anti-s. mansoni antibodies. a statistical correlation was found between the ind ... | 1977 | 848648 |
| unisexual infections with schistosoma haematobium in the white mouse. | in unisexual infections with an iranian strain of schistosoma haematobium in white mice, female worms matured normally and deposited eggs in the liver but these eggs did not contain miracidia. both female and male worms grew to more than half the length of corresponding mated worms in bisexual infections, and males acquired the normal number of testes. | 1977 | 848652 |

| renographic studies in vesical schistosomiasis in children. | renal function in children infected with schistosoma haematobium and in uninfected controls has been studied with the i131 hippuran renogram. the results suggest that renographic abnormalities which persist after a water-load are more common in infected children who have heavy egg-output in their urine, and abnormal pyelograms. specific chemotherapy restored the renogram to normal within 3 weeks in several cases. it is suggested that the renogram is useful for the assessment and followup of pati ... | 1975 | 1119668 |
| studies on schistosomiasis in somalia. | a survey was made on the prevalence and intensity of schistosomiasis in 14 localities in 4 areas in somalia has revealed the presence of urinary bilharziasis among the inhabitants of all these localities, this being much higher in the two areas where water development has been accomplished. the mean prevalence of infection was found to be 27.2% and 58.1% in the two areas where water development has only been planned, while it was 58.7% and 75.6% in the two areas where the extension of irrigation ... | 1975 | 1119669 |
| the relation of worm burden to passage of schistosoma haematobium eggs in the urine of infected patients. | patients scheduled for cystectomy for bladder carcinoma or exstrophy of the bladder were studied. the number of eggs per day passed in the urine preoperatively was compared with the number of worms recovered from the cystectomy specimen by dissection. a mean of 203 embryonated schistosoma haematobium eggs per day per worm pair were recovered from the urine of active, untreated cases. the relation between the number of s. haematobium females recovered and the number of living eggs passed in the u ... | 1975 | 1119670 |
| suppression of delayed hypersensitivity in schistosome-infected patients by niridazole. | niridazole, an anti-parasitic drug, suppresses manifestations of delayed hypersensitivity and retards allograft rejection in laboratory animals. we investigated the immunosuppressive effects of the standard antihelminthic regimen of niridazole (25 mg/kg/day for seven days) in five patients with schistosomiasis. although 15-minute skin reactions to schistosomal antigens remained unchanged, niridazole reduced or ablated positive 48-hour skin reactions to tuberculin (ppd), mumps and schistosome ant ... | 1975 | 1124104 |
