Aims: The Carapa procera species is used of traditional for its antimicrobial properties especially for the skin. Its oil is used for various applications including the production of soaps used for personal hygiene and other skin conditions. The purpose of this study is to assess the antibacterial properties of soaps formulated from the oil of this species. Place and Duration of Study: The units of organic biological chemistry and structural organic chemistry of the UFR Structural Sciences of Matter and Technology (Université Félix Houphouet-Boigny) for the manufacture of soaps and the bacteriology unit of the Institut Pasteur de Côte d'Ivoire for bioassays between January 2019 and February 2020. Methodology: The antibacterial evaluation was carried out by the disc method on nutrient agars with determination of bacterial parameters (MIC and MBC). Discs of usuals antibiotics (Tetracycline, Rifampicin and Ampicillin) were used as a control to assess this activity as well as a commercially soap. Results:  The inhibition diameters obtained from these different test soaps vary from 16.00 - 17.15 mm; 15.75 - 17.70 mm and 20.33 - 24.00 mm respectively on growth of the bacterial strains E. coli, P. aeruginosa and S. aureus. Unlike unscented soaps, scented soaps have the best inhibition diameter zones values. Moreover, the best MBC values (25 mg/mL) are obtained with the 2 soaps in fresh or aged state on the S. aureus strain against 50 mg/mL on the 2 other strains. In addition, with the exception of the E. coli strain which is resistant to Tetracycline, the 2 other strains are sensitive to all the antibiotics tested. In addition, this study also shows variability in the effect of soaps on these targets. Conclusion: Soaps formulated from Carapa procera oil do indeed possess antibacterial properties that could justify its usage against dermatoses in traditional medicine.

Type 2 diabetes or diabetes mellitus is a metabolic disorder characterized by an increase in blood sugar level. It is caused by a lack of insulin secretion, insulin action, or both. There are approximately 501,530 people living with diabetes in Côte d'Ivoire with an estimated prevalence of 5.19% in 2013. Unfortunately impairment of zinc and copper leads to increased oxidative stress, insulin resistance and diabetic complications. The study aimed to assess the zinc and copper status in patients with type 2 diabetes. This study involved 80 type 2 diabetics and 80 non-diabetic as controls. Glycated hemoglobin (HbA1c) was analyzed in whole blood using the Hitachi Roche Cobas C311. The serum assays of zinc and copper then of glycemia were carried out using a flame-air / acetylene atomic absorption spectrophotometer (AAS) of the brand Varian Spectr AA-20 Victoria, Australia and on the Cobas C311 respectively. A significant decrease in zinc content (P ˂ 0.0001) and a significant increase in copper content as well as the Cu / Zn ratio (P ˂ 0.0001) were observed in type 2 diabetic patients compared to nondiabetic control. The lower serum zinc values and the high Cu / Zn ratio could justify the high level of oxidative stress in patients with type 2 diabetes. Assessment of zinc and copper is essential in the monitoring of complications due to type 2 diabetes.

Objective: The treatment management of Multidrug-Resistant Tuberculosis (MDR-TB) is a major global public health problem. The development of this form of tuberculosis increases immune deficiency and the production of free radicals in the body. Micronutrients, especially fat-soluble vitamins A, D, and E, play an essential role in the immune system by protecting and renewing cells. The objective of this study is to determine the profiles of vitamins A, D, and E in order to evaluate the performance of the immune defenses of MDR-TB under second-line anti-TB treatment.Methods: The analysis of vitamins A, D and E was carried out using an HPLC chain, in isocratic mode by UV-Visible detection after prior extraction of the lipid fraction from the serum in the hexane protected away from light.Results: MDR-TB showed a significant decrease in the concentration of vitamins A, D, and E (p˂0.05) with high reduction levels of 80%, 40% and 50%, respectively. Conclusion:The persistence of this deficit after six months of TB treatment highlights the need for corrective measures to be taken, such as the supplementation of vitamins A, D, and E.
