Effectiveness of forced rehydration and early re-feeding in the treatment of acute diarrhoea in a tropical area
S. Pignatelli, J. Simporè, M. Ruggieri, S. Musumeci
Background: The administration of oral re-hydration solution (ORS) via continuous infusion through a nasogastric (NG) tube and early refeeding facilitates delivery in hospitalised children and the return back home.
Design: the observation was made during a one-year stage in the Camillian Medical Centre (CMC) of Ouagadougou in Burkina Faso.(...)

Extraction, partial purification and characterization of β-amylase from the bulbs of G. klattianus
Mamoudou H. Dicko , M.J.F.Searle-van Leeuwen , R. Hilhorst , A. S. Traore¬
The bulbs of Gladiolus klattianus are used in Burkina Faso in food processing. Activities of α-amylase and β-amylase were reported within those bulbs for the first time. The purification of the β-amylase involved buffer extraction, ammonium sulfate precipitation and gel filtration chromatography. The enzyme was purified 47 fold with 75% yield,(...)

Extraction, partial purification and characterization of beta-amylase from Gladiolus klattianus
DICKO Mamoudou. H., Searle-van LEEUWEN, HILHORST, R. and TRAORE, A. S.
The bulbs of Gladiolus klattianus are used in Burkina Faso in food processing. Activities of a-amylase and b-amylase were reported within those bulbs for the ®rst time. The puri®cation of the b-amylase involved bu€er extraction, ammonium sulfate precipitation and gel filtration chromatography. The enzyme was puri®ed 47 fold with 75% yield, giv(...)

Improved kinetic parameter estimation in pH-profile data treatment
I T Some, P Bogaerts, R Hanus, M Hanocq, J Dubois
Statistical problems in temperature stability parameter estimation have been the subject of many papers whereas statistics in, pH-profile parameter estimation have focused little attention. However, the conventional two step method used in data treatment in both cases leads to identical statistical problems. The aim of this study is then to in(...)

Bromoenol lactone enhances the permeabilization of rat submandibular acinar cells by P2X7 agonists
E. KABRE
The uptake of ethidium bromide by acini incubated at 37°C in the presence of 1 mM ATP increased
with time and reached after 5 min about 10% of maximal uptake measured in the presence of
digitonin … The response to ATP was dose-dependent (half-maximal concentration around
40 μM) and it was decreased when the temperature was lowered to 25°(...)

Nucleation and growth in electrodeposition of metals on n-Si(111)
R. Krumm a, B. Guel b, C. Schmitz a, G. Staikov a,*
Initial stages of electrodeposition of Tl, Cd and Cu on n-Si(111) from sulfate electrolyte solutions are studied using cyclic voltammetry and chronoamperometry. Capacitance measurements in metal ion free solutions were used to determine the flat band potential of n-Si. Results show that the relative position of the metal equilibrium potential(...)

Le sacré et le système politique traditionnel des Dagara du Burkina à l'épreuve de la colonisation
Magloire Somé
Cet article montre comment les religions traditionnelles africaines structures à la fois le mode de pensée et le système politique des sociétés précoloniales. La colonisation n'a pas pu entrer une rupture avec le système de croyances et le système politique traditionnel qui lui survivent et paraissent garder une vigueur malgré le choc colonial(...)

Les stratégies de développement de l’Église catholique au Burkina Faso de 1960 à 1983
Magloire Somé
L’Église catholique s'est engagée dans le processus du développement au Burkina à la fois par tradition d'action sociale et par une obligation morale dictée par le contexte politico-économique et social du monde contemporain. Pendant longtemps, cet engagement lui a valu une influence sociale importante au regard même de la diversité et de la m(...)

Isolation and characterization of Desulfovibrio burkinensis sp. nov. from an African ricefield, and phylogeny of Desulfovibrio alcoholivorans
A. S. Ouattara, B. K. C. Patel, J.-L. Cayol, N. Cuzin, A. S. Traore and J.-L. Garcia
A sulfate-reducing bacterium, strain HDvT (T¯type strain), was isolated from an anoxic ricefield soil. Cells were Gram-negative, non-sporulating curved rods motile by means of a single polar flagellum. Cytochrome c3 and desulfoviridin
were present. In the presence of sulfate, glycerol, 1,2- and 1,3-propanediol, dihydroxyacetone, pyruvate, lac(...)

Incorporating batch effects in the estimation of drug stability parameters using an Arrhenius model
I T Some, P Bogaerts, R Hanus, M Hanocq, J Dubois
The nonlinear estimation of drug stability parameters (energy of activation E a and shelf-life t Y) by conventional approaches employs equations relating drug content determination C at time t and temperature T. The identification procedures lead to the determination of only one initial drug content C 0 for several different experiments. Howev(...)

Study on the activation of phospholipases A 2 by purinergic agonists in rat submandibular ductal cells
E. KABRE
Extracellular ATP and benzoyl-ATP (Bz-ATP) increased the release of [3H] arachidonic acid ([3H] AA) from prelabeled rat submandibular gland (RSMG) ductal cells respectively two-and threefold. Both agonists also increased the release of [3H] AA from acini but at a lower level (+ 50% and+ 100% respectively). Carbachol had no significant effect o(...)

E. KABRE
Isolated ductal cells of rat submandibular gland phospholipid pools were labeled with [3 H] arachidonic acid (AA). The tracer was incorporated preferentially to phosphatidylcholine (46% of the lipidic fraction). Extracellular ATP induced the release of [3 H] AA to the extracellular medium in a time-and dose-dependent manner (EC 50= 220 μ m). A(...)
