    Notes: Abstract Fish catches from the coral reefs of the Tulear region (southwest Madagascar), are analyzed based on fish landings. This region of the island consists of two barrier reefs, two coral banks, three lagoon reefs and a fringing reef. The total reef area studied was 190 km2. Of the whole fishing area, the reef flat was the most frequently used by fishermen. Line catches per unit efort (CPUE) were stable throughout the eight month sampling period (6 to 8 kg/trip to sea), whereas gillnet and seine catches showed differences between the cold period and the warm period. These results appear to be representative of the artisanal fishery catches in the southwest Indian Ocean. Annual fish yield was estimated at 12 t km-2 yr-1. Comparable yields have been recorded in certain regions of the Indo-Pacific, that have similar ratios of coral reef area to adjacent shallows and similar fishing practices. Reef species (Lethrinidae, Siganidae) dominated the catches. At present, coastal waters of the Tulear region are heavily fished, and the fishermen report a progressive decrease in the average size of fish caught over the last 15 years. Management measures are suggested, based on preliminary findings.

    Notes: Summary The plasma pharmacokinetics of pantoprazole have been investigated following single intravenous infusion and single oral administration at a dose of 40 mg to 12 healthy male subjects in a randomised cross-over study. Both treatments were generally well tolerated and no relevant compound-related adverse events were noted. The plasma pharmacokinetics of pantoprazole following intravenous infusion in this group of subjects were characterised by a total plasma clearance of 0.13 l·h−1·kg−1 and apparent terminal elimination half-life 1.9 h. The apparent volume of distribution estimated at steady state (0.171·kg−1) was compatible with the localization of a major fraction of the compound in extracellular water. Following oral administration as an enteric-coated tablet formulation, a variable onset of absorption was followed by rapid attainment of maximum plasma concentrations of pantoprazole. Pantoprazole was well absorbed following oral administration; the absolute systemic bioavailability of the compound was estimated as 77% (95% CI, 67 to 89%).

    Notes: Abstract Famciclovir has been shown to have potent and selective activity against herpesviruses. The possibility of a pharmacokinetic interaction between the anti-viral agent, famciclovir and allopurinol has been investigated in twelve healthy male volunteers following a single oral dose of famciclovir (500 mg) in the presence and absence of steady-state levels of allopurinol (300 mg). Similarly, the pharmacokinetic profiles of allopurinol and oxypurinol prior to and following a single dose of famciclovir were compared. Mean values of Cmax, AUC and terminal-phase half-life for penciclovir following administration of famciclovir alone at 3.3 μg·ml-1, 8.8 μ·h·ml-1 and 2.1 h, respectively were unchanged by co-administration of allopurinol. Similarly, mean urinary recovery and renal clearance values of penciclovir following famciclovir alone were 56.8% and 271·h-1, and when given with allopurinol 59.7% and 27.51·h-1, respectively. No evidence of accumulation of the inactive precursor to penciclovir, BRL 42359, was noted as a result of co-administration of the two drugs. Mean steady-state Cmax, AUC and terminal-phase half-life values for allopurinol after co-administration of allopurinol with famciclovir also appeared unchanged from values obtained after dosing of allopurinol alone, at 2.12 μg·ml-1, 5.73 μg·h·ml-1 and 1.38h, respectively. Mean Cmax and AUC values of the active metabolite of allopurinol, oxypurinol were 11.2 μg·ml-1 and 96.0 μg·h·ml-1, respectively, and these were also unaltered by co-administration of famciclovir with allopurinol, with values of 10.6 μg/ml and 89.8 μg·h/ml, respectively. In summary, no evidence of a pharmacokinetic interaction between allopurinol and famciclovir was observed when the two drugs were given concomitantly to healthy volunteers.

    Notes: Gillnet sampling was conducted for a year in a tropical mangrove creek (SW Madagascar), characterized by a limited freshwater influence, a high turbidity and a tidal range up to 3 m. Sixty species of juvenile fishes were caught, 44 species being of commercial interest. Catches were dominated by Gerreidae (27% of total abundance), Teraponidae (16%), Carangidae (13%) and Sparidae (12%). The temporary resident fishes in the mangrove zone represented 50% of the species and 97% of the total abundance, the other species being rare (less than five individuals). The species richness, abundance and biomass per netting were low in the middle of the cool season (July-August). Monthly changes in the fish assemblage were particularly complex, with three species groups displaying a clear seasonal pattern, some species succeeding one another in a rather unstructured way, and three species abundant throughout the year. There was no clear structuring effect of temperature, salinity and turbidity on the fish assemblage. However, tidal, lunar and diel effects on the composition of the fish assemblage were evident. The species overlap between the Sarodrano mangrove fauna and the adjacent coral reef fauna is particularly weak with six species in common and shows that the mangrove plays only a very limited nursery role for coral reef species.

    Notes: The effects of 100 mg and 200 mg bedtime doses of cimetidine on nocturnal gastric acid secretion were examined in nine healthy subjects in a double blind, placebo controlled, randomised three way crossover study. Treatment was given at 23.00 hours and the gastric contents continually aspirated from midnight until 07.00 hours the following morning. Hourly aliquots were analysed for pH and acid output. Relative to placebo the 100 mg and 200 mg doses of cimetidine respectively increased mean pH by 2.22 and 2.63 units/h (P 〈 0.001) with mean acid output decreasing by 0.95 and 0.98 mmol/h (P 〈 0.001). Whilst mean pH was higher and mean acid output was lower for 200 mg cimetidine compared to 100 mg cimetidine the difference was not statistically significant. Mean hourly pH was consistently above pH 3 for 100% of the time for both doses of cimetidine whereas mean pH failed to reach this value at anytime on placebo.Low doses of cimetidine taken at bedtime effectively reduced nocturnal gastric acid secretion in healthy individuals.
