| plasma levels of metrifonate and dichlorvos during treatment of schistosomiasis with bilarcil. | metrifonate (0,0-dimethyl-[1-hydroxy-2,2,2-trichloroethyl]-phosphonate), and its rearrangement product dichlorvos (2,2-dichlorovinyl dimethyl phosphate) (ddvp), were studied in plasma from two patients with schistosomiasis who were treated with bilarcil. a mass fragmentographic technique was used. isotopic variants of the substances were used as internal standards and to compensate for ddvp formed during the workup procedure. the results were related to erythrocyte and plasmacholinesterase deter ... | 1980 | 7386721 |

| study of bilharzial uropathy by means of hippuran i131 extended renography. | renal, ureteral, and vesicle functions were evaluated in 209 patients with obstructive lesions of the ureter due to schistosomiasis haematobia (bilharziasis), using hippuran i131 extended renography. high values for tmax. and t 1/2 were noted for both kidneys irrespective of radiological diagnosis of a left- or right-sided lesion. a high percentage of residual vesicle urine was demonstrated in a number of patients with bilharzial uro-obstructive lesions. the incidence of vesicoureteral reflux in ... | 1980 | 7406107 |
| a study on the etiological factors of bilharzial bladder cancer in egypt: 5-urinary nitrite in a rural population. | urinary nitrite was present in 5.6% of 2379 individuals from a rural population infested with "schistosoma haematobium". a higher frequency was observed in symptomatic patients with active bilharzial cystitis (25%) and patients with bladder cancer associated with schistosomiasis (66.2%); conversely, urinary nitrite was absent in normal urban individuals. the frequency of urinary nitrite was higher in females (6.4%) than males (4.6%), and was more frequent in adults than extremes of age. the pres ... | 1980 | 7414706 |
| hybrids between schistosoma haematobium and s. mattheei and their identification by isoelectric focusing of enzymes. | some biological features of f1 hybrids between south african strains of schistosoma haematobium and s. mattheei are described and compared with those of both parental species. the distinctive patterns of the g6pd and pgm isoenzymes, resolved by isoelectric focusing, of both species and of the hybrid are defined and the results of enzyme analyses of parasites isolated from human infections in the transvaal are reported. these show that hybridization does occur naturally in man and that the shape ... | 1980 | 7434427 |

| comparative karyology of the freshwater snails bulinus tropicus and b. natalensis. | species of the subgenus bulinus s.s. occur in a polyploid series which is of interest because of the rarity of polyploidy in animal species and because there appears to be a relation between ploidy level and ability to transmit schistosoma haematobium, a parasite of major public health importance. we describe a technique for the preparation of standard karyotypes using cell suspensions from colchicine-treated embryos. the results for two diploid species, b. tropicus (krauss) and b. natalensis (k ... | 1980 | 7448622 |
