As If

Using three columns of different depths (1.10m, 8.40m and 10.40m), we investigated the possibility of Biomphalaria glabrata moving towards deep regions. In the 1.10m column, we noted that locomotion can occur in two manners: 1) when the foot is in contact with the substrate: a) sliding descent; b) sliding ascent; c) creeping descent; d) creeping ascent, 2) when the foot is not in contact with the substrate: a) sudden descent without emission of air bules; b) sudden descent with emission of air bules; c) sudden ascent. In the 8.40m column containing food on the bottom (experimental group), the snails remained longer at this depth when compared to those of the group which received no food (control). The sliding behavior was characteristic of locomotion occurring at 0 to 1m both in upward and downward directions. Creeping behavior was typical for the ascent of the snails that reached deeper levels. When the snails were creeping, the shell remained hanging as if it were heavier, a fact that may have been due to water entering the pulmonary chamber. In the 10.40m column, the snails slid downward to a depth of 4m or descended suddenly all the way to the bottom. Ascent occurred by creeping from the bottom to the surface. In the 8.40m and 10.40m columns, copulation, feeding and oviposition occurred at the deepest levels.

AbstractThe effect of artesunate (ART) on the survival time of adult worm pairs of Schistosoma mansoni and on their egg output during in vitro culture was assessed. ART significantly decreased the survival time of both paired male and female worms at concentrations of 5, 10, 20 and 40 mg l− 1 during in vitro cultivation. An inhibitory effect of ART on the daily egg output of paired female worms during in vitro cultivation was also observed.

Two new spirostane saponins namely (25 R)-6α-[(β-D-glucopyranosyl)oxy]-5α-spirostan-3β-yl β-D-galactopyranoside (1) and (25 R)-6α-[(β-D-glucopyranosyl)oxy]-27-hydroxy-5α-spirostan-3β-yl β-D-glucopyranoside (2), together with three known metabolites (25 S)-5β-spirostan-3-β-yl O-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside (3), (25 R)-5α-spirostan-3-β-yl O-β-D-galactopyranosyl-(1→2)- O-β-D-glucopyranosyl-(1→4)-β-D-galactopyranoside (4) and (25 R)-5α-spirostan-3-β-yl O-β-D-glucopyranosyl-(1→3)- O-[β-D-xylopyranosyl-(1→2)]- O-β-D-glucopyranosyl-(1→4)-β-D-glactopyranoside (5) were identified from the leaves of Asparagus sprengeri Regel (Asparagaceae). Determination of the structures was based on chemical and spectroscopic data (HRESI-MS/MSn, 1H, DEPT 13C NMR, 1H-1H COSY, HSQC and HMBC). The dry powder, the 1-butanol extract of the leaves, and the isolated compounds (3–5) exhibited molluscicidal properties against Biomphalaria alexandrina snails (the intermediate host of Schistosoma mansoni) [LC90 = 150, 40, 7, 10 and 13 ppm, respectively], while compounds 1 and 2 were molluscicidally inactive.
