diabète. L'objectif de cette étude était de recenser les plantes utilisées en médecine traditionnelle pour traiter le diabète dans la région Maritime du
Togo. Méthodes: De janvier 2013 à juin 2014, une enquête ethnobotanique a été réalisée auprès de 164 guérisseurs traditionnels dans la région
Maritime par des interviews directes à l'aide d'un questionnaire semi structuré. Résultats: Les données recueillies ont permis d'identifier 112
espèces végétales appartenant à 51 familles. Les familles les plus représentées ont été les Caesalpiniaceae / Fabaceae avec 9 espèces, suivie des
Euphorbiaceae et des Compositae avec 8 espèces chacune. Les espèces les plus citées ont été Allium sativum, Alium cepa, Guilandina bonduc,
Moringa oleifera et de Picralima nitida qui ont eu une valeur usuelle de 0,05. En termes de recettes, 132 recettes sont préparées à partir des 112
espèces de plantes. Les recettes à plantes uniques ont été au nombre de 78, tandis que 54 recettes sont obtenues par des associations de plantes.
Les parties de plantes les plus utilisées ont été les feuilles suivies par les racines. La principale méthode de préparation reste la décoction.
Conclusion: La région maritime du Togo dispose d'une biodiversité floristique importante en matière de plantes antidiabétiques. Ces résultats
constituent une bonne base de données pour le criblage biologique dans la recherche de molécules antidiabétiques à base des plantes.

It is designed to carry out haematological, microbiological, immunoserological, parasitological and mycological analyses. 8 The aim of this paper is to summarize the literature on the germ responsible for typhoid fever, its pathophysiology and the role of the laboratory in managing the disease. Material and methods A systematic search was carried out in the Pub Med and google scholar databases using the following keywords Typhoid fever, Epidemiology, Physiopathology, laboratory, medical biology, typhoid fever, for articles and selected references of these articles. The 58 selected articles deal with epidemiological studies of typhoid fever, the prevalence of the disease worldwide, the medical biology laboratory, technological approaches to eradicating the disease, etc. Case definition Definitions are those of the WHO Typhoid Fever Surveillance System. 9 Confirmed case laboratory confirmation by culture or molecular methods of Salmonella typhi or detection of S. typhi DNA from a normally sterile site.

However, journals analysing the work of antifungal activities of plants in West Africa in recent years are rare. This study is a synthesis of publications from 2006 to 2021 on plants traditionally used in the fight against antifungal diseases. A systematic search was carried out in the Pub Med and Google Scholar database using the following keywords: vaginitis; West Africa; antifungal activity; medicinal plants; plant extracts; for articles published from 2006 to 2021. These selected articles focus on ethnobotanical studies, in vitro antifungal tests and molecules isolated from these plants. A total of 46 papers were selected from 7 West African countries with 56 plants studied. Nigeria and Ivory coast did more work with 22 and 14 papers respectively and studied more plants with 23 and 17 respectively. 43% of plants show good activity in vitro on strains of Candida albicans in the laboratory with a minimum fungicide concentration and a ...

For sanitary safety, it is important to know its physico-chemical and microbiological qualities in order to better understand the risks incurred by the population. The aim of this study was to analyze Adétikopé’s domestic wastewater from a microbiological and physico-chemical standpoint. Twelve wastewater samples were taken in Adétikopé from December 2022 to February 2023. Physico-chemical parameters were determined in accordance with AFNOR and the French NF standard. In microbiology, AFNOR was used as a reference for the detection of germs contaminating wastewater. Results were assessed in relation to European Union Criteria 98/83/EC. The wastewater analyzed has a pH close to neutral, with an average pH of 7.05. The pollutant load generated ranged from 32 mG/L to 201 mg/L for BOD5, from 660 mG/L to 900 mG/L for COD and from 408 mG/L to 2080 mG/L for suspended solids. The highest levels of germs were detected in the samples tak...

In Africa, where the increase in the urban population and the growing demand for consumer goods are driving up the rate of waste production, waste collection and disposal are posing serious problems, not only for municipal and central government officials, but also and above all for the local population. In Togo, and more specifically in the city of Lomé and the surrounding area (Greater Lomé), as in other African cities, the average annual production is estimated at 305340 tonnes, of which 89428 tonnes are collected and buried, giving a collection rate of 29.29%. A tiny proportion of the waste collected (9,000 tonnes, or 2.95%) is recycled as compost by associations and/or NGOs. The three key players who share this task are the local authority, the formal sector and the informal sector. Objective: The aim of this study is to assess the current state of waste management in Greater Lomé, which poses...

The objective of our review is to identify and present the nutritional potential of these two agro-resources. We conducted a literature review on the two products in scientific databases and articles over the period 2016-2017.Soymilk, one of the end-products of Glycine max (soy), is a highly nutritious drink containing a high quality protein which can greatly contribute to strengthen some human body functions. Regarding M. oleifera , it’s called “miracle plant” because of the usefulness of all its parts in nutrition, medicine and cosmetic. Therefore, the association of soy and moringa thanks to different processing methods would help to obtain mixed products restoring nutritional balance. Keywords: Glycine max , Moringa oleifera , nutritional value, processing methods, mixed products

Methodology and results: The toxicity test was performed by oral administration of the extract to rats while diabetes was induced with streptozotocin, the 250, and 500 mg / kg body weight. The results of the toxicity tests revealed no evidence of mortality or morbidity suggesting an LD50 greater than 5000 mg / kg. Similarly, the biochemical and haematological parameters remained unchanged. In antidiabetic tests, there was a progressive decrease followed by a normalization of the glucose level of the treated rats. Overall, the extract at 250 and 500 mg / kg body weight resulted in a significant reduction in glycated haemoglobin, amylase, lipase, G6PD and serum lipids. Conclusion and application of results: This study revealed that, the treatment with the recipe might repair oxidative damages, hyperglycaemia and hyperlipidaemia in d...

Les pathologies infectieuses d’origine staphylococcique ne cessent de causer des pertes de vies humaines malgre l’evolution spectaculaire de l’antibiotherapie. En effet Staphylococcus aureus , bacterie ubiquitaire, douee d’une remarquable capacite de survie dans un environnement defavorable ou meme hostile dispose d’un fort pouvoir pathogene. Cette evolution imprevisible des resistances, particulierement dans nos regions ou la pression de selection medicamenteuse est tres importante, doit inciter a une surveillance reguliere de la sensibilite des especes bacteriennes predominantes aux differents antibiotiques utilises. Objectifs : Determiner la prevalence de S. aureus meti-R et pour objectifs specifiques d’etudier la sensibilite des isolats vis-a-vis de la meticilline et de determiner la prevalence de la meticillinoresistance pour les SCN d’une part et pour le S. aureus d’autre p...

L’Education Relative a l’Environnement (ERE) dispose d’une approche didactique qui se veut la transmission des valeurs de l’enseignant vers l’apprenant a travers un dispositif destine a transmettre le savoir, le savoir-faire et surtout le savoir-etre et d’en permettre le reinvestissement. Il est a constater que ce schema n’est pas exact en ce qui concerne le reinvestissement des acquis de la formation en ERE. Du point de vue des sciences de l’education, la question se pose : quel est la part dispositif de formation dans le degre de reinvestissement des acquis de la formation en ERE. Objectifs : Evaluer la part du dispositif de formation dans le degre de reinvestissement d’acquis de l’ERE. Materiel et methodes : Nous avons menees une enquete exploratoire dans les zones urbaines a fort degre d’insalubrite ou existent pourtant des associati...

Il est estime qu'entre 70-80% des Togolais utilisent la MT pour la gestion courante des soins de sante. De l’analyse de la situation effectue en 2007 par l'Organisation ouest-africaine de la sante (OOAS) pour evaluer le niveau de developpement de la MT dans ses Etats membres, il en ressort des disparites enormes entre les pays dans la volonte politique des gouvernements pour le developpement de la MT. Objectif : Evaluer le degre d’implication de la MT dans le traitement des maladies et les collaborations officielles qui existent entre les tenants des deux medecines au Togo. Resultats : Le secteur de la MT est organise en association. Des centres ont vu le jour a l’instar du Centre d’Etude et de Recherche en MT (CERMETRA) et du Centre de Recherche et de Formation sur les Plantes Medicinales (CERFOPLAM). Certaines associations ou particulier ont re...

Au XXeme siecle, de nombreux chercheurs se sont interroge sur le processus d’apprentissage. Tout le monde connait Pavlov et son chien, la majorite des enseignants ont egalement etudie les travaux de Piaget sur les phases de developpement de l’enfant et de l’adolescent. Aujourd’hui, la theorie cognitiviste et constructiviste, assez connues chez les enseignants, ne se concretisent pas toujours dans les programmes, les volumes et les evaluations offerts aux enseignants. L’enseignement, et surtout l’evaluation, restent essentiellement behavioriste. La maitrise de ces theories s’avere donc indispensable. Objectifs : elaborer une synthese des differentes theories de l’apprentissage et relever le lien entre ces theories et celles de l’education. Materiel et methode : nous avons effectue une recherche documentaire sur les approches pedagogiques utilisees dans l’educatio...

The main method used to evaluate this impact is structural equation model analysis method (SEM). The empirical results showed that perceived learning outcome is statistically influenced by three factors including learning assistance, community building assistance and perceived motivation. Of which, the community building assistance factor was found to play a strong role of students’ perceived learning outcome. Therefore, building solutions to develop of perceived motivation and community building assistance of the system in order to improve E-learning usage in Can Tho university should be paid attention in the coming time.
