          Abstract

          The urea and uric acid contents in the hemolymph of Bradybaena similaris were analyzed under starvation and Eurytrema coelomaticum infection during 30 days. The urea and uric acid contents in the uninfected and fed snails were 15.090 mg/dl and 9.399 mg/dl, respectively, being the urea/uric acid ratio 1.6. The urea content in starved snails increased to a maximum of 363.237 mg/dl at 15 days, and the uric acid varied to a maximum of 11.470 mg/dl. The urea content in infected snails was reduced to a minimum of 2.123 mg/dl at 30 days of infection and the uric acid increased significatively at 25 days post exposure, being 13.820 mg/dl. A significative relation was not observed between the time of starvation and time of E. coelomaticum infection and the uric acid content in the hemolymph of B. similaris.

          O conteúdo de uréia e de ácido úrico na hemolnfa de Bradybaena similaris foi analisado em função da inanição e da infecção com Eurytrema coelomaticum ao longo de 30 dias. O conteúdo destas substâncias em moluscos não infectados e alimentados foi, respectivamente, 15.090 mg/dl e 9.399 mg/dl, sendo a relação uréia/ácido úrico 1.6. A concentração de uréia nos moluscos em inanição aumentou até um valor máximo de 363.237 mg/dl, aos 15 dias de inanição e o conteúdo de ácido úrico variou até um valor máximo de 11.761 mg/dl, aos 10 dias de jejum. A concentração de uréia em moluscos infectados foi reduzida até um valor mínimo 2.123 mg/dl, aos 30 dias de infecção, e o conteúdo de ácido úrico aumentou significativamente aos 25 dias de infecção, sendo 13.820 mg/dl. Não foram observadas relações significativas entre o tempo de inanição e o tempo de infecção com estágios larvais de E. coelomaticum e o conteúdo de ácido úrico na hemolinfa de B. similaris.
