Abstract
Vegetable production in Togo is seriously affected by pests attack. To reduce damage, farmers indiscriminately use pesticides. Various studies have reported high concentrations of pesticide residues more than acceptable limits in vegetables and other edible food. The aim of the presented study is to study the attitudes and practices developed by vegetable growers about pesticides applications. A standardized questionnaires which included socio-professional factors, provisions and operations concerning the use of varieties of pesticides were addressed to 150 growers in vegetable farms along the Littoral of Togo. In order to complete data concerning pesticides, seven runoff private companies and agents of the 'Direction de la Protection des Végétaux' were interviewed. Data were statistical treated using Sphinx Plus. The survey showed that vegetable growers have an acceptable educational level (36% have more than 7 years of formal education) to exploit instructions concerning pesticide use, but more than 97% do not use recommended tools. Only 21% of them received training for pesticide use. Moreover, 84% of them did not usually wear gloves, and less than 30% used oro-nasal masks. Failure to observe minimum intervals between pesticide application and sale is worrying because extremely hazardous (Carbofuran and Cadusaphos) or moderately toxic (Cypermethrin, Dimethoate, Endosulfan, Chlorpyrifos-ethyl, Fipronil) are the products currently used. The presented study indicates that pesticides application in the survey area represents a potential risk for the environment, farmers and consumers. More investigations are needed to quantify pesticides residues on the vegetables currently con,umed and moreover, to determine the potential effect of those products on human and animals health.

Abstract
The present investigation was carried out to evaluate the safety of hydro-ethanol extract of Bridelia ferruginea Benth (Euphorbiaceae) root bark. For acute toxicity study, a single dose of 2000 and 5000 mg/kg of the B. ferruginea root bark extract was given orally to healthy male Wistar rats and Balb/c mice. The animals were observed for mortality and clinical signs for 3 h and then daily for 14 days. In the sub-chronic toxicity study, the extract was administered orally at doses of 250, 500 and 1000 mg/kg/day for 28 days to male Wistar rats. Animals were sacrificed to examine their organs, and urine and blood serum were analyzed. In the acute toxicity study, B. ferruginea root bark extract caused neither significant visible signs of toxicity, nor mortality in Wistar rats and Balb/c mice. In sub-chronic toxicity study, administration of the B. ferruginea root bark extract at 250, 500, and 1000 mg/kg for 28 consecutive days to Wistar rats did not produce mortality. No significant differences were found in relative organ weights, biochemical studied parameters in treated groups compared to control group. No obvious histological changes were observed in organs of B. ferruginea extract treated animals compared to controls.

Abstract
Ethnobotanical knowledge is useful in development of management and conservation of plant genetic resources. In this study, ethnobotanical investigations were conducted in Sudanian zone of Togo to identify use values knowledge of Sterculia setigera tree. Information was obtained with the aid of semistructured interviews. Three (3) ethnic groups: Bassar, Moba, and Konkomba belonging to ten (10) localities were investigated. Use knowledge of Sterculia setigera through these ethnic groups was assessed using four use indices: reported use (RU), plant part value (PPV), specific reported use (SU), and intraspecific use value (IUV). Sixty (60) informants of 43 years old were interviewed. The plant parts values and specific uses are raised more in the Moba's ethnic group. The main quoted uses are medicinal, religious, food, and cosmetic. Thus, fourteen (14) treatments of ailments are assigned to it. Considering the various uses, it is crucial to validate scientifically the therapeutic uses and safety of these plants through phytochemical screening, different biological activity tests, and toxicological studies.

Abstract
Vitex doniana is traditionally used in Togo to treat various diseases including wounds. The aim of this work was to evaluate the efficiency of Vitex doniana on cutaneous wound healing. Wounds were induced in ICR mice divided into four groups as following: Group I received carbopol 974P NF empty gel, Groups II and III were treated topically with carbopol gel containing 2.5% and 5% of Vitex doniana extract. Group IV received Betadine® 10% as standard drug. The efficacy of treatment was evaluated by planimetry and histological analysis. We secondary used the gel containing Vitex doniana at 2.5% and the pure extract at 10 mg/ml on the model of ear edema induced by xylene. Skin toxicity test was performed with the gel containing Vitex doniana at 5% and the pure extract at 30 mg/ml. Vitex doniana at 5% and 2.5% provided better wound contraction (91.14% and 86.38%) at day 12 post-excision when compared to control (51.15%). The results of histological evaluation supported the outcome of excision wound model. Moreover Vitex doniana inhibited significantly edema induced by xylene when compared to control (p< 0.05). In skin toxicity test, no abnormal symptoms were developed over 14 day-time period. Vitex doniana inhibits the topical inflammation and accelerate cutaneous wound repair.

Abstract
Many medical centres are equipped with a sonograph. However, a sonographist is not always present or is not trained in all of the specialised domains of sonography. . A sonogram is not always possible due to a lack of physicians. This situation has given rise to the concept of remote-controlled sonography: tele-sonography, a medical procedure used in remote sonographic diagnosis in real time or deferred time. Tele-sonography can now be carried out in real time by the transmission of the expert's procedure (robotic system) or by the use of a 3D sonograph in real time. These modes of real time tele-sonography rely on expensive technologies requiring budgets and an infrastructure that is not always possible in developing countries where the needs in tele-medicine are increasing. This paper aimed to present a preliminary evaluation of a "low cost" system of sonographic tele-expertise in real time and the deferred sonographic telediagnosis accompanied by a tele-mammography between expert sites (university hospitals) and isolated sites (peripheral hospitals, dispensaries).

Abstract
The purposes of this study were: (1) to describe the genetic variability of HIV strains found in Burkina Faso, (2) to characterize non-B HIV strains mutation profiles selected by ARVs and (3) to detect possible resistances induced by ARV drugs. From 30 October 2002 to 20 November 2003, 132 HIV 1-positive patients taking Highly Active Antiretroviral Therapy (HAART) for more than one year in Bobo-Dioulasso and Ouagadougou were included. T-CD4+ lymphocytes count was done using Dynabeads technique while genotypic test and ARV-resistance tests were conducted using Pol sequencing that codes for reverse transcriptase reverse, integrase and protease. Due to undetectable viremia, 86 samples out of 132 could not be characterized. Whereas in the 46 others that had a viral load exceeding 1000 copies mL(-1), the following HIV-1 subtypes were identified: CRF06 (54,55%); CRF02(38,63%); CRF01 (4,55%) and subtype A (2,27%). In addition, several mutations related to PI, NRTI and NNRTI resistance were isolated in 27 samples. This study found a huge genetic HIV-1 polymorphism in Burkina Faso. The level of acquired resistance to ARV after one year of treatment amounted 20.4%. These results clearly show that there is imperative need to set up an ARV resistance surveillance network in Burkina Faso to guide treatment strategies and follow the extension of the phenomenon in the country.

Abstract
The root bark of Cassia sieberiana was analyzed using direct analysis in real time mass spectrometry, and a main flavonoid component with an [M + H](+) mass of 275 was identified. The flavonoid, epiafzelechin, was isolated and fully characterized with the concerted use of NMR spectroscopy, circular dichroism, and optical rotation. Electronic circular dichroism and optical rotation TDDFT calculations were also performed, and their agreement with the experimental results confirmed the enantiomeric identity of the isolated natural product. The antioxidant activity of the compound was also investigated.

Abstract
BACKGROUND Malaria continues to be of great concern in Togo, as it accounts for high mortality rates, principally in children. Although plant-based medicines are the only means in major malarious regions of the country, still very little is known about the medicinal plants and medical practices of the indigenous people. OBJECTIVE The present study aimed to document the indigenous medicinal plant utilization for the management of malaria and related symptoms in Togo Maritime Region. METHODOLOGY Fifty Traditional Healers (TH) were selected with the help leaders of Togolese Traditional Healers Associations and information on their knowledge on the use of plants for malaria therapeutic purposes was gathered using a semi-structured interviews. RESULTS After enquiries, 52 plant species belonging to 49 genera and 29 families were recorded. The most represented families were Rubiaceae and Rutaceae with four species each. Traditional healers agreed more in the treatment of malaria (ICF=0.70), fever (ICF=0.33) and anemia (ICF=0.20). For the treatment of malaria, 38.46% (20/52) of the species cited in the study were of high fidelity level (FL=100%). The leaves (58.22%), leafy stem (33.78%) and fruits (8.52%) were the most used parts in concoctions. The main mode of preparation was decoction (69%) and the administration was essentially by oral route (79%) and body-bath (14%). CONCLUSION The issue of the study showed that Togo Maritime Region TH have a good knowledge of antimalarial plants. However the study must be extend to the whole country to lead to innovative strategies in malaria control. Such results could be a starting point for in vitro antimalarial screenings.

Abstract
Aloe buettneri A. Berger is commonly used in traditional Togolese medicine to treat inflammatory and gastric ulcers. The present study examined the gastro-protection effect of the hydro-alcoholic extract of A. buettneri on mucus production and gastric pH. A gastric ulcer is induced by ethanol 95° alone (1 mL/kg body weight), after pre-treatment with indomethacin (300 mg/kg) or by utilising L-NAME (40 mg/kg IV). In addition gastric mucus was removed by scraping and subsequently weighed. The experiment focused entirely on rats that had been subjected to fasting. The hydro-alcoholic extract of A. buettneri (500 mg/kg) significantly inhibited ulcers that were induced by ethanol, indomethacin or L-NAME pre-treatment. A. buettneri was shown to increase the production of gastric mucus. Furthermore L-arginine significantly decreased the size of the induced ulcers. The results achieved in the study carried out suggest that A. buettneri posses gastro-protective properties.

Abstract
A total of 684 Hisex Brown day-old chicks were studied. The chicks were randomly assigned into three groups as follows: (1) chicks with immediate feed access; (2) chicks with 48 h delay in feed access, and (3) chicks with 72 h delay in feed access. For each group, chicks were assigned into 4 replications of 57 birds each. Prior to feed access, the chicks were weighed. Samples of chicks were used to weigh yolk sac at 1, 3 and 7 days and to collect blood at 1, 3, 7, 14 and 56 days. Also, reared chicks were weighed weekly. The results indicated that chick weights decreased during the holding period. Yolk sac utilisation was similar between groups, while morbidity and mortality increased linearly with the duration of delay in feed access. At 56 days, chicks having delayed access to feed were lighter than those without delay in feed access. Serum concentration of glucose up to 14 days and of total protein and triglycerides until 56 days decreased with the increasing duration of delay in feed access. It can be concluded that delayed feed access is detrimental to the juvenile performance of layer-type chicks and has a negative age-related effect on the serum concentrations of glucose, triglycerides and total protein.

Abstract
BACKGROUND Monitoring the antibiotic resistance of microorganisms in a specific geographic area can be useful in developing new approaches to first-intention antibiotherapy. OBJECTIVE The purpose of this study was to describe the evolution of resistance of Staphylococcus aureus to antibiotics routinely used at Saint Camille Medical Centre in Ouagadougou, Burkina Faso from 1996 to 2006. METHOD Strains of S. aureus, isolated from various pathologic sources were tested to determine their susceptibility to antibiotics. Sensitivity tests were performed in accordance with the guidelines of the Antibiogram Committee of the French Society for Microbiology (version 2007). RESULTS During the study period, 1160 staphylococci strains were isolated including 73.45% identified as S. aureus. Susceptibility tests demonstrated a significant increase in resistance to beta-lactam antibiotics. The proportion of strains showing resistance to ampicillin reached 58.29% in 2000. Resistance to these antibiotics regressed significantly from 2000 to 2006. Resistance to pristinamycin and erythromycin showed a tendency to increase while resistance to gentamicin and oleandomycin showed no statistically significant change. CONCLUSION This study demonstrated that S. aureus was the most common Staphylococcus genus present at the center and that it was resistant to several antibiotics. Reducing use of beta-lactam probably accounted for the significant decline in resistance to this type of antibiotic. Care should also be given to the use of other antibiotics such as pristinamycin and erythromycin since resistance appears to be increasing.

Abstract
AIM OF THE STUDY In Africa, medicinal plants are used intensively and concomitantly with allopathic medicines in the treatment of opportunity diseases by many patients or by healthy person to prevent diseases. However, there is little information about the interactions between medicines and botanical products used currently in West Africa area. Therefore, the aim of the present investigation is to study the effect of some plant products on CYP3A4, CYP3A5 and CYP3A7, three individual enzymes of CYP3A subfamily, in vitro. MATERIALS AND METHODS Teas and ethanolic extracts of medicinal, food and co-administered plants were evaluated on CYP3A4, CYP3A5 and CYP3A7 individual enzymes in vitro using fluorometric assays. RESULTS Extracts of adjuvant plants such as Aframomum cuspidatum, and Aframomum melegueta, as well as one medicinal plant (Harrisonia abyssinica) inhibited CYP3A4, CYP3A5 and CYP3A7 activity more than 90%. Phyllanthus amarus showed high inhibition of CYP3A5 and CYP3A7. Food plants (Solanum macrocarpon and Talinum triangulare) inhibited CYP3A4 and CYP3A5 less than 20%. CONCLUSION These results indicate that plants tested in this study affect in vitro the activity of the main three CYP3A subfamily enzymes. These active plants could interfere with the metabolism at phase I of conventional drugs in vivo as well act as pharmacoenhancers in herbal mixtures.
