  We reported the results of biological and toxicological study, realized on Mitragyna inermis Willd Oktze, one specie of family of Rubiaceae, well known in traditional medicine in Burkina Faso for his intensification potentialities of resistance against multiple pathologies like infectious and parasitic diseases, adynamia, rheumatic and osteoarthritis diseases. So we have formulated hypothesis of stimulation of organism’s defenses for a scientist research. The steeping freeze-dried of the plant’s product has been used for different assays: General acute toxicity estimation on Ico mouse (NMRI Han) by intraperitoneal route and orally administration on rabbit from the value of LD50 obtained with the mouse. Biological study: The kinetic interaction between the plant’s product chemical group and the evolution of biological elements medium of immunity on the rabbit, has been appreciated. The biological elements include white blood cells, red blood cells, lymphocytes, platelets, total proteins, albumin and globulins. The following results have been obtained about the study: A Lethal Dose (LD50) resulted from maceration (acute general toxicity) at the rate of 800 mg kg-1 of corporal weight showing a bit toxic product. An interaction between vegetable’s extract chemical group and biological elements of rabbit which is expressed by: An increasing (13 to 18%) of total proteins from serum; this increasing was notably after 24 h of administration. Albumin decreasing of 10% in comparison with initial rate, indicated haptens action of plant’s extract chemical products. α1, α2, β and γ globulins increasing, respectively 46.8, 14.31 and 26% during the first day of administration of the extract. A lymphocyte increasing of 35% 24 h after administration of the product. This rate is more increased after the second administration; White blood cells are also increasing. These results show an obvious capacity of the plant’s macered extract to stimulate organism natural defenses in relation with antigenous-antibody reaction. This will be an interesting perspective for complementary treatment of pathology like HIV diseases.

  β-lactamase production ways and inhibition patterns were investigated in cell suspensions of clinical isolates. The purpose of this research was prior to investigate the different β-lactamase molecular classes occurring in Burkina Faso owing to the local practice of β-lactam antibiotics. The use of specific inhibitors enabled to draw up an inhibition profile and consequently to assign an enzyme to accurate molecular class of β-lactamase. At the same time, β-lactamase expression ways were explored and correlated to the inhibition profiles. The current results pointed out two main groups of organisms. The first group of isolates secretes β-lactamases mainly by inducible way. Interestingly this bacterial group carries molecular class C of β-lactamase. The second group of isolates uses partial inducible and partial constitutive way for enzyme expression. These bacteria mostly carry molecular class A of β-lactamases. The sole exception encountered during these investigations is an organism, expressing exclusively by the constitutive way an enzyme that is found to belong to molecular class B of β-lactamases.

  In this study the total phenolic and flavonoid content as well as the antioxidant activity of six Acanthaceae namely Blepharis lineariifolia PERS, Dicliptera verticillata (FORRSK.) C. CHRISTENS, Dyschoriste perrottetii (NEES) O. KTZE, Hygrophila auriculata (SCHUMACH.) HEINE, Lepidagathis anobrya NEES, Nelsonia canescens (LAM) SPRENG were evaluated. The total phenolic and flavonoid of their aqueous acetone extract were assessed by Folin-ciocalteu and AlCl3 method, respectively, whereas the antioxidant activities were determined by the DPPH method. Lepidagathis anobrya, Hygrophila auriculata and Nelsonia canescens which had the highest phenolic content, were found to possess the best antioxidant activities. The results suggest that these plants are good sources of antioxidants and support their use in cardiovascular and antiinflammatory diseases.

  The aim of the present study was to evaluate some enzymes inhibitory effects of 11 plant species belonging to 9 families from Burkina Faso. Methanolic extracts were used for their Glutathione-s-transferase (GST), Acetylcholinesterase (AChE), Carboxylesterase (CES) and Xanthine Oxidase (XO) inhibitory activities at final concentration of 100 μg mL-1. The total phenolics, flavonoids and tannins were also determined spectrophotometrically using Folin-Ciocalteu, AlCl3 and ammonium citrate iron reagents, respectively. Among the 11 species tested, the best inhibitory percentages were found with Euphorbia hirta, Sclerocarya birrea and Scoparia dulcis (inhibition>40%) followed by Annona senegalensis, Annona squamosa, Polygala arenaria and Ceratotheca sesamoides (inhibition>25%). The best total phenolic and tannin contents were found with S. birrea with 56.10 mg GAE/100 mg extract and 47.75 mg TAE/100 mg extract, respectively. E hirta presented the higher total flavonoids (9.96 mg QE/100 mg extract). It's was found that Sclerocarya birrea has inhibited all enzymes at more than 30% and this activity is correlated to total tannins contents. Contrary to S. birrea, the enzymatic activities of E. hirta and S. dulcis are correlated to total flavonoids contents. Present findings suggest that the methanolic extracts of those plant species are potential inhibitors of GST, AChE, CES and XO and confirm their traditional uses in the treatment of mental disorders, gout, painful inflammations and cardiovascular diseases.
