    Abstract: Viral etiologies especially viral hepatitis B remain an area of concern sub-Saharan Africa with a variable prevalence between countries. Ethnobotanical knowledge of medicinal plants used in the treatment of viral hepatitis, in particular, viral hepatitis B, was conducted in the District of Dakar (Senegal). Forty-two participants were surveyed, which included  18 herbalists, 19 Traditional medicine practitioners (TMPs)and 5 resource persons. Fifty-one plant species were documented from forty-seven genera and thirty families. The most frequently mentioned families were; Fabaceae (11 species); Meliaceae, (4 species); Rubiaceae and Combretaceae (3 species each); Annonnacaea, Malvaceae, Rutaceae and Asteraceae (2 species each). All other families were represented by a single species. The decoction was the most common method of préparation (66.66%).  Leaves and trunk bark were the plant parts of the plant most used. The most commonly used species were: Tinospora bakis (85.71%), Gardiena ternifolia (73.8%), Calotropis procera (71.42%), Carica papaya (66.66%), Citrus aurantifolia (64.28%) and Cochlospermum tinctorium (61.9%). It is concluded that the hepatoprotective properties of these plants are certainly induced by chemical compounds that will have to be identified later through phytochemical research.

    Abstract: HIV / AIDS infection is characterized by the reduction of the body's defenses favoring the occurrence "opportunistic" infections, as bronchitis, mycoses and tuberculosis etc. Thus, to fight against this virus, antiretrovirals are used. The Ziguinchor district (Senegal) has a higher seroprevalence rate of 2.2% above the national average of 0.7%. It is in this sense that a survey of two herbalists, 35 tradipraticians and eight resource persons was conducted to identify the plants used in the management of opportunistic AIDS diseases because as the populations often resort to phytotherapy. 88 plants were identified and divided into 79 genera and 38 families. Some species were mentioned very more frequently and in many diseases. These are: Cordila pinnata Poir. (78%), Guiera senegalensis (73.1%), Khaya senegalensis (67%), Icacina oliviformis (55%), Terminalia macroptera (55%), Cassia sieberiana (47%), etc. Leaves and roots constituted the greatest use in the form of macerated, infused, for drinking, bathing, or fumigation, etc. The expected result during this study was the establishment of a repertory of medicinal plants used for the management of opportunistic diseases.

    Abstract: Background : Nowadays with the appearance of diseases such as cancer, atherosclerosis, free radicals are often singled out. What motivates scientific research in natural antioxidants. Aim/Objective : The aim of this study was to determine the antioxidant activity of the stalks and the fruit of Solanum melongena L. Study Duration : The period of the study was done on 25th July, 2015 at the Department of Pharmacy, Faculty of Medecine, Pharmacy and Odontology, University of Dakar, Senegal. Methodology : Antioxidant activity was evaluated through two methods (DPPH and FRAP). Results : For the FRAP test, at the highest concentration (83.3 µg/ml) the aqueous extract of the fruit (0.90±0.08) has a higher reducing power compared to those of ethanol extracts from the fruit (0.77±0.41) and the stalk (0.85±0.004). These results remain inferior to that of tannic acid (0.95± 0.0005). The DPPH test reveals that the ethanolic extract of the fruit is more effective in reducing the free radical DPPH with an inhibitory concentration 50 (IC 50) equal to 3.37±0.03 μg / ml, followed by the ethanolic extract of the stalks (IC 50 = 4.46±0.24 μg / ml) and finally the aqueous extract of the fruit (IC50 = 9.6±0.026 μg / ml). Conclusion : These results make it possible to confirm the in vitro activity of the parts studied, but in vivo studies are necessary in order to know the acute and chronic toxicities. Finally, perform a bio-guided fractionation to determine the molecules responsible for the antioxidant activity.

    Abstract: An ethno-apicultural survey was carried out for the plant species pollinated by honey bees in the green district of Casamance (South Senegal). This survey followed a well-established questionnaire concerning beekeepers in these areas. The listed melliferous flora was made of 61 species either. It’s divided into 58 genera and 30 families though the most represented are in decreasing order Fabaceae with 12 species (19.67%) followed by Rutaceae and Malvaceae with 4 species (6.55% each), Arecaceae, Anacardiaceae, Combretaceae, Gramineae, Myrtaceae, with 3 species (4.91% each), then Chrysobalanaceae, Lamiaceae, Meliaceae and Rubiaceae with 2 species (3.27% each) and then Acanthaceae, Asteraceae, Canabaceae, Verbenaceae, Apocynaceae, Bignoniaceae, Annonaceae, Hymenocardiaceae, Icacinaceae, Lauraceae, Moringaceae, Musaceae, Celastraceae, Rhizophoraceae, Sapindaceae, Sterculiceae, Moraceae, Ochnaceae, with 1 species (1.63% each). Melliferous plants include 47.54% nectariferous plants followed by nectariferous polliniferous plants with 37.70% and finally polliniferous species with 14.75%. This study enabled us to identify eight (08) species with high melliferous value. To enhance the value of these plants, further studies on foraging activity and nectar production will be led to prove their real melliferous potential.

    Abstract: The first discovery of Plasmodium vivax infections in Senegal used archived patients’ sera in place of blood pellet, the preferred specimen for the molecular diagnosis of Plasmodium species. The present study assessed the reliability of detecting P. vivax DNA in plasma in comparison to blood pellet from the same patient’s samples. Methods A total of 616 blood samples obtained from febrile patients living in Kolda (2015 and 2020), Tambacounda (2017 and 2020), and Kedougou (2020) regions in Senegal, were first screened for Plasmodium species composition by 18S ssrRNA-based nested PCR. Paired blood pellets and plasma samples were selected from a subset of 50 P. vivax -positive patients matched by age and sex with 50 P. vivax -negative patients, and subjected to a cytochrome b-based qPCR to compare the detection and quantification of P. vivax genomic DNA between the two specimen types. Results and discussion The study reports 1.8% and 14.77% of single and mixed P. vivax infections in the study population, and a high concordance (84%) between the qPCR detection of P. vivax genomic DNA from paired blood pellets and plasma samples. Importantly, all P. vivax negative samples from the blood pellets were also confirmed plasma-negative, and parasitaemia in blood pellets was higher compared to plasma samples. The results support investigations of P. vivax infections in archived sera or plasma collections with a high degree of confidence to generate additional data on the neglected P. vivax malaria, and ultimately guide strategies to control the disease.

    Abstract: Background: The use of plants for healing dates back to very remote times. Nowadays with the accession of new diseases plants are increasingly used for the formulation of new drugs able to overcome the many diseases (cancer, atherosclerosis) often caused by the disorder of the system prooxidant/antioxidant. Aim/Objective: On the strength of this observation, the research of an antioxidant plant is essential, hence the aim of this study, which is to determine the antioxidant activity of the stalk and the fruit of Solanum aethiopicum L. Methods: The fruits and stalk were washed, cut into fine slats, then dried in the incubator for three days and finally crushed into powder. An extraction by decoction with ethanol (stalks and fruits) and water (fruit) was subsequently carried out to obtain three extracts (ethanol and water). Antioxidant activity was evaluated through the FRAP method, and the trapping of radical DPPH. Results: For the FRAP method, at the highest concentration (1 mg/ml) the aqueous extract of the fruit (74.84±2.97%) has a higher reducing power compared to those of the ethanolic extracts of the fruit (70.15 ± 5.72%) and the stalk (49.85 ± 2.11%). These reducing powers, although significant, remain lower than those of tannic acid (89.95±0.007%). And finally, for the DPPH method, the aqueous extract of the fruit is more effective in reducing free radical DPPH with a IC50= 162±33 µg/ml, follow up by ethanol extract from the stalk (IC50= 360± 90 µg/ml) and finally ethanol extract from the fruit (IC50= 362.5± 23.5 µg/ml). These results confirm the in vitro antioxidant activity of the studied parts of Solanum aethiopicum. Conclusion: Prospective studies could focus on acute and subacute toxicities and the determination of the molecules responsible for the activity.

    Abstract: This study has surveyed honey plants used by Apis mellifera in the Great Green Wall  of Senegal by  involving 38 people (21 in Widou, 17 in Koyli Alpha). The study  revealed seventeen species divided into fourteen genera and nine families. Fabaceae was the most represented family with 5 species followed by Combretaceae (3 species), Malvaceae and Rutaceae each with 2 species, and Anacardiaceae, Balanitaceae, Rhamnaceae, Sterculiaceae, Meliaceae each with one species.  The most frequent melliferous plant species were : Combretum glutinosum, Guiera senegalensis, Balanites aegyptiaca, Acacia radiana, Lannea acida, Terminalia avicennoides, Sclerocarya birrea, Sterculia setigera and Maytenus senegalensis. The trees were more large with 58.82% followed by shrubs (35.29%) and herbs (5.88%). Spontaneous plants represent 76.47% and cultivated plants represent 23.53%. The melliferous flora was largely dominated by African and Afro-Indian species, which together accounted for 70.58% of the species. According to their apicultural value, the nectariferous species represented 58.82% and the reamining were  polleniferous (41.18%). The species that bloom in the rainy season were more numerous with 52.94% of the species. This  study enabled  us to identify  nine (09) species with  high melliferous value. Further studies on foraging activity and nectar production would be highly useful to test real melliferous potential of these plants and their value further.
