| a retrospective survey on side effects of praziquantel among 25,693 cases of schistosomiasis japonica. | a retrospective survey involving 25,693 persons was carried out in four provinces and the city of shanghai, china between december 1981 until may 1982 to document relatively serious side effects of praziquantel used in a mass treatment programme for schistosomiasis japonica. only 122 or 0.47% of those participating in the study had experienced relatively serious side reactions to the drug. most had only one kind of side effects but two or more were recorded in a few patients. neuropsychiatric re ... | 1983 | 6673126 |

| 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 |
