Les Accidents Vasculaires Cérébraux (AVC) sont une urgence de santé publique. Le présent travail vise à évaluer, dans la pharmacopée ivoirienne, les connaissances des phytothérapeutes puis à identifier les préparations médicamenteuses utilisées dans le traitement des séquelles des AVC, à déterminer leurs caractéristiques ethnopharmacologiques, phytochimiques, leur potentiel antioxydant et leur toxicité pour une meilleure prise en charge des malades. Les résultats des enquêtes réalisées auprès de 20 phytothérapeutes du Programme National de Promotion de la Médecine Traditionnelle (PNPMT) ont montré que l’hypertension artérielle est la principale cause des AVC et l’hémiplégie, la séquelle majeure. Parmi les 36 préparations collectées, 10 parmi les extraits aqueux ont fait l’objet de tests. Les résultats indiquent la présence de polyphénols, de flavonoïdes, de tanins, de stérols et de saponosides dans toutes les préparations. Daoutra Fort et Daoutra 3 sont celles qui ont présenté les teneurs les plus élevées en polyphénols (173913,8 et 151456,9 µg EAG/g MS) et en flavonoïdes (77,13 %et 75,07 %). Les résultats indiquent également que Ballo (CI50 = 0,0280 mg/mL), Daoutra Fort (0,0409 mg/mL) et Daoutra 3 (0,0593 mg/mL) présentent d’importants potentiels antioxydants. Les tests de toxicité aigüe ont indiqué que, pour les préparations, la DL50 est supérieure à 5000 mg/kg de pc. Elles peuvent être considérées comme non toxiques par voie orale. ABSTRACT Stroke are a public health emergency. The present work aims to evaluate, in the Ivorian pharmacopoeia, the knowledge of phytotherapists then to identify the medicinal preparations used in the treatment of the sequelae of stroke, to determine their ethnopharmacological and phytochemical characteristics, their antioxidant potential and their toxicity for a better taking in charge of the sick. The results of surveys carried out with 20 phytotherapists from the National Program for the Promotion of Traditional Medicine (PNPMT) showed that high blood pressure is the main cause of stroke and hemiplegia, the major sequel. Of the 36 Piba et al., 2020 Journal of Animal & Plant Sciences (J.Anim.Plant Sci. ISSN 2071-7024) Vol.46 (2): 8197-8211 https://doi.org/10.35759/JAnmPlSci.v46-2.4 8198 preparations collected, 10 of the aqueous extracts were tested. The results indicate the presence of polyphenols, flavonoids, tannins, sterols and saponosides in all preparations. Daoutra Fort and Daoutra 3 are those which presented the highest contents of polyphenols (173,913.8 and 151,456.9 µg EAG / g DM) and of flavonoids (77.13% and 75.07%). The results also indicate that Ballo (IC50 = 0.0280 mg / mL), Daoutra Fort (0.0409 mg / mL) and Daoutra 3 (0.0593 mg / mL) exhibit significant antioxidant potential. Acute toxicity testing indicated that for preparations the DL50 is greater than 5000 mg / kg bw. They can be considered nontoxic by the oral route.

Abstract The primary goal of this study was to investigate the possibility of using early life stages of white sturgeon (Acipenser transmontanus) (eggs, larvae and fry) as a species relevant to the Fraser River, B.C., for the acute and sublethal toxico-logical testing of forest industry effluents. Here we report the first successful acute toxicity tests for 8-day-old larvae and 42-day-old fry exposed to several chemicals known to be released into the Fraser River (i.e., 6 monochlorovanillin [6 MVAN], 4,5 dichloroguaiacol [4,5 DCG], 4,5 dichlorocatechol [4,5 DCAT], pentachlorophenol [PCP], and didecyldimethylammonium chloride [DDAC]). In most cases, white sturgeon fry were at the lower end of the range for acute toxicity values for chlorinated phenolic compounds, when compared with other juvenile fish species, and they were extremely sensitive to DDAC. The larval stage was usually more sensitive than the fry stage. Acute toxicity tests with fertilized eggs were unsuccessful. A postexposure growth study was inconclusive because neither control nor toxicant-exposed larvae and fry withstood the additional handling used for measuring body mass. At 62-days-old, fry were more tolerant of handling. This allowed measurement of their swimming performance. Although we have concerns about the reliability of using larvae for acute toxicity testing at this time, 60-day-old white sturgeon fry would appear to be both a sensitive and relevant species for assessing environmental impacts relevant to the Fraser River.
