RESUMEN
The etiology of rotavirus in acute diarrhoeal illness in children 0-5 years of age, admitted to the Pediatric wards of Kasturba Medical College Hospital, Manipal was studied, over a period of one year. Rotavirus in the faecal samples detected by the slide latex agglutination test accounted for 14.9% of the diarrheas with maximum incidence in the 7-12 months of age group (57.5%). Bacterial enteropathogens continued to play a significant role in diarrheal diseases. Salmonella enteritis was found more in the age group 0-6 months and shigellosis in 37-60 months. In a control study of 100 children who had no diarrhea, 2 were found positive for rotaviruses.

Foram estudadas 15 substâncias de estrutura naftoquinônica obtidas de síntese química: a própria 1,4-naftoquinona sem substituintes, um derivado com um radical hidroxila na posiçäo 2 e 13 derivados hidroxilados apresentando diferentes grupos metileno-amino na posiçäo 3. As culturas de células foram protegidas com as drogas antes da titulaçäo dos vírus (pólio 1, Coxackie B4 e ECHO 19). Pela determinaçäo do índice de inibiçäo virótico (IIV) mostrou-se que o ECHO-vírus 19 foi o mais inibido. Dos 14 compostos testados, 3 deles mostraram um IIV significativo contrao ECHO-vírus como segue: IIV de 1,75 para 2-HO-1,4-naftoquinina e 2-HO-3 (N-morfolil)-metil-1, 4-naftoquinona e IIV de 3,75 para 2-HO-3-N-benzil-N'(N-benzil-2-etilamina) -1,4-naftoquinona. Este último composto mostrou atividade virucida, em experiência paralela, significando que a droga afeta diretamente a partícula viral

Some derivatives obtained by chemical transformation of lapachol (a natural substance extracted from the core of plants belonging to the family Bignoniaceae) vere studied as to their posible antiviral action. Cell cultures were treated with those substances and then inoculated with poliovirus type 1, echovirus 19 and Coxsackievirus B type 4. Only ß-lapachone, succinamidyl-ß-norlapachone and intermediary of Hooker have shown a significant viral inhibition index to echovirus type 19. Those derivatives had in in vitro ion but they did not cause any harm to the viral particles studied (virucidal action)
