Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and transportation of red blood cells (RBCs) in blood vessels, leading to various clinical complications. Sickle cell disease is a widespread genetic disease in Black Africa. The objective of this study was to evaluate the sickling inhibition activity of Griffonia simplicifolia. Quantitative and qualitative tests were used to determine the major groups of secondary metabolites present in the Griffonia simplicifolia leaves extracts and the modified Emmel test was used to perform the study of sickling inhibition activity. The OECD 423 toxicity study showed that at a single dose of 2000 mg/kg bw, Griffonia simplicifolia leaves extracts are not toxic. All tested substances inhibit erythrocyte falciformation in a dose-dependent manner. The percentages of inhibition were 50.35%, 73% and 94.23% for aqueous extract, hydromethanolic extract and phenylalanine respectively at the concentration of 15 mg/mL. The methanolic extract (70%) had higher activity compared to the aqueous extract. These results suggest that the Griffonia simplicifolia extracts have some potential to be used as alternative antisickling therapy in SCD management.

Natural plant products have been used by the population of the south-eastern part of Côte d’Ivoire in the management of sickle cell anemia. This study was aimed at investigating the antisickling activity of the hydro-ethanolic extract of a combination of the leaves of J. secunda, J. gossypiifolia and P. nigrescens. These three plants species were used in the Ivorian traditional herbal medicine. Preliminary phytochemistry was carried out using standard methods. As for the sickling reversal test, the Hb SS blood sickling was induced with 2% sodium metabisulfite. After 120 minutes of incubation, the plant extract was added. Every 30 minutes for a period of 120 minutes, a drop of the prepared solution was observed at (40×) magnification and the percentage of reversion calculated. The phytochemical analysis revealed the presence of Alkaloids, Flavonoids, Polyphenols, Catechic Tannins, Sterols and Polyterpenes. The results of the reversal test showed that the percentage of sickling reversal effect of the combination of the plants (75.00 ± 4.33b,c) was highly superior than the negative control (10.17 ± 0.55d) but was significantly (p J. secunda: 83.50 ± 2.33<

Introduction: Sexual assault is an act of a sexual nature perpetrated on another person without their consent. Goal: To describe the epidemio-clinical aspects and the medical management of sexual assault in the Segou region. Methodology: This was a retro-prospective descriptive study from September 2010 to September 2018 on the alleged female victims of sexual assault registered in the Gynecology and Obstetrics departments of the hospital and the sanitary quarters of Ségou. Results: We recorded 107 cases of sexual assault out of 47,729 gynecological consultations, representing a hospital prevalence of 0.22%. The victims were between 10 and 15 years old in 48.59% of the cases. Students were the most represented with 53.27% (57/107) of cases. Genito-genital contact was recorded in 90.65% (97/107) of cases. Vulvo-perineal lesions were present in 44.86% (48/107) of survivors. Hymenial deflowering was the most frequent traumatic genital lesion accounting for 43.70% (21/48) of old cases and 27.00% (13/48) of recent cases. Sexual assault was committed by a single individual in 60.75% (65/107) of cases and by a friend of the victim in 21.5% (23/107) of cases. The survivors had consulted within 24 hours of the sexual assault in 53.27% (57/107) of the cases, the treatment was medical in 68.22% (73/107) and medical-surgical in 4.7% (5/107), post-exposure prophylaxis to the Human Immunodeficiency Virus (HIV) was performed in only 26.16% (28/107) of survivors. Conclusion: Sexual assault remains a concern although its frequency is low. This scourge mainly affects children and adolescents, and the lesions are mainly genitals.
