One of the plants that has been used by the community is cherry (Muntingia calabura L.) which is a lush plant, easy to breed, often on the side of the road, allowed to grow as a shade tree. Traditionally used to treat bleeding wounds, festering and burns, inflammation of the walls of blood vessels accompanied by blood clots in their channels. Fresh or dried cherry leaves are used as a medicine for wounds by finely grinding them and placing them on the wound. The use of cherry leaves directly in the treatment of wounds is not liked by the community, so they tried to formulate it in the form of cream preparations. Based on this, the researchers conducted a phytochemical screening and formulation of cherry leaf extract in cream preparations as well as tested its effectiveness for treating wounds. Extraction was carried out by percolation using 80% ethanol. Phytochemical screening was carried out on fresh leaves, simplicia, and ethanol extract of cherry leaves. And formulated into cream preparations with concentrations of 2.5%, 5% and 7.5%. The effectiveness for wound healing was carried out on artificial incisions on the back skin of male guinea pigs infected with Staphylococcus aureus bacteria. Measured decrease in wound diameter and observation of the width of the pus and the amount of edema. The results of the phytochemical screening test showed that there were the same groups of chemical compounds in fresh leaves, simplicia, and ethanol extract of cherry leaves, namely alkaloids, flavonoids, tannins, triterpenoids/steroids. The greater the concentration of EEDK in the cream, the faster the wound will heal. On the 16th day, 5% EEDK; 7.5%; and gentamicin provide 100% perfect wound healing. Means that the ethanol extract of cherry leaves at a concentration of 5% has a very good ability to heal incisions infected with Staphylococcs aureus.

A study based on spatial distribution of Scorodophloeus zenkeri was performed in the device 400ha Biaro forest. Both specie has multiple uses, including industrial exploitation by the quality of wood. An inventory of the forest potential of these specie were made based on values in abscissa (x) and ordonna (y) for all individuals. At the end of this inventory, 9115 feet were counted with 9098 feet at reserve Yoko and 17 individuals at Biaro forest. The spatial distribution of individuals of both specie is aleator type at reserve Yoko and aggregated type at Biaro forest.

Objective: the study was planned to determine the frequency of late recourse to antenatal consultations (ANC) in the City Province of Kinshasa, and to identify the socio-demographic, cultural, economic and obstetric determinants; to help improve maternal and child health. Method: This is an analytical cross-sectional study conducted in October 2018 in the health zone of Matete and that of N'sele. 456 mothers took part by answering a questionnaire made available to them with supporting explanation. Data were statistically analyzed using jamovi 1.6.23 software. Descriptive analyzes and logistical regression made it possible to achieve the purpose of the study. Results: 74.1% of mothers had initiated ANC late. The main determinants were: residence in the N'sele’s Health Zone [OR = 3.61 (2.04 – 6.39); p ˂ 0.001]; low level of education [OR = 10.07 (2.68 – 37.87); p ˂ 0.001] or secondary level [OR = 4.61 (1.78 – 11.98); p≤0.002]; marriage [OR = 1.93 (1.04 – 3.59); p ≤ 0.037] as well as dietary restrictions during pregnancy [OR = 2.20 (1.11 – 4.36); p≤0.024]. Conclusion: the frequency of late recourse to antenatal consultations is very high in the City Province of Kinshasa. Strategies to encourage women to initiate early antenatal visits should focus on improving socio-demographic, cultural, economic and obstetrical conditions without forgetting the political and health aspects. The cultural consideration will have to hold the attention of the decision-makers or investigators to the projects related to this problem.
