Abstract: Okra is a plant rich in nutrients and is very well consumed in Côte d’Ivoire. Despite its many benefits, the production of this vegetable is still weak in our country. The reasons for this include the inadequate selection of varieties, the high cost of inputs and the poverty of the soil for its cultivation. One of the alternatives for sustained production is to solve the problem of soil fertility. In the case of our work, the aim is to improve the yield of okra. To achieve this goal, experiments were undertaken to evaluate the impact of activated charcoal on morphological parameters of a local okra variety. For this purpose, the charcoal used was activated in three different times (activation time equal to 0 days, 15 days and 30 days). The experimental device used is a split-plot with three repetitions, each comprising 12 elementary plots. The various charcoals were buried the same day. Then, the seedling was done with two positions including outside position and inside position. Observations were made on 360 plants. An analysis of the variances was carried out on the morphological parameters. Fruit mass is the variable most influenced by activated charcoal. Thus, the greatest value of the mass was obtained with the charcoal CA0, with outside position.

Abstract: Cassava root is shortly preserved after harvesting due to its tanning and rapid physiological decomposition. Consequently, the commercial value is reduced and the craving of its finishes products. With an aim of improving physiological quality, post harvest food value “the effects of bleaching and conservation in silo-pits were evaluated. Four (04) varieties of cassava: Bocou1, Bocou2, Bocou3 and Yavo were collected fresh and healthy in 13 months of maturity. They were subjected to a bleaching (65°C /15 - 30 s) followed by a kinetic conservation (7 days of intervals) in silo-pit (1 × 0.6 × 0.5 m). Results show that Bocou2 variety has the high proteins content (2.64% ± 0.01%), followed by hydrocyanic acid (8.21 ± 0.01 mg/100 g) and total carotenoids (26.7 μg/100 g). The conservation influences positively the protein content, reducing sugars content, the dries matter content and the total phenolic compounds for all the varieties excluded Bocou2 variety whose protein content drops. As regard of the fat contents, a weak increase is observed. The sensory analysis reveals that the boiled cassava of the Yavo variety is more appreciated followed by Bocou1 variety. Concerning the Attiéké, Bocou3 variety gives the more appreciated dish followed by the Yavo variety. In conclusion, the silo-pit conservation after bleaching improves the physiological quality of the cassava and the sensory taste even during 14 days. This study has a huge impact of reducing the post harvests losses and increases the commercial value of cassava in the world.

Abstract: Tuberculosis represents a main concern for public health worldwide. In poor countries, the most prevalent method for bacteriological confirmation re- mains Smear Sputum Microscopy (SSM). This study objective was to assess clinical performances of Loop Mediated Isothermal Amplification for TB detection (Lamp-TB). Sputum of patients presenting symptoms consistent with tuberculosis were collected according to the National Tuberculosis Control Programme guidelines in Centre Antituberculeux de Yopougon. SSM after Ziehl-Neelsen staining and TB-Lamp were blindly performed with spot sputum specimen. Samples, transported at Institut Pasteur de Cote d’Ivoire were decontaminated according to N-acetyl-L-cystein (NALC) method. In Mycobacteria Growth Indicator Tube (MGIT), 500 μl of pellet were inoculated and incubated in MGIT 960 instrument. MPT64 antigen was detected on positive culture. Of 500 patients enrolled, 469 were included. Clinical isolates of M. tuberculosis Complex were detected for 157 (33.5%). Comparatively to culture, Sensitivity and Specificity of SSM were 86% (95% Confidence interval (CI): 81% - 91%) 96% (95%IC: 94% - 98%) respectively. TB-Lamp Sensitivity was 92% (95%CI: 88% - 96%), and Specificity 94% (95%CI: 91% - 97%). Positive Predictive Value of SSM and TB-Lamp was 91.8% and 88.8% respectively. Negative Predictive Value of TB-Lamp assay was 95.7% whereas this of SSM was 93.3%. Positive Likelihood Ratio was 15.3 for TB-Lamp and 21.5 for SSM 21.5 whereas negative Likelihood of TB-Lamp was lower than SSM. Active tuberculosis was detected in162/469 (34.5%) with TB-Lamp and 147 (31.3%) with SSM. TB-Lamp assay performances estimated from sputum samples may improve detection of active TB cases in routine.

Abstract: Le massif montagneux du Yaouré, situé entre le Bandama Blanc et le Bandama rouge (ou marahoué), est une zone de transition entre la forêt dense au Sud et la savane arborée au Nord. Le climat de la région correspond au régime équatorial de transition atténué (climat baouléen). Les rares affleurements observés sur les flancs des collines sont altérés en schistes argileux jaunatres, riches en pyrite Sur les sommets, se retrouvent des cuirasses latéritiques souvent polygéniques, à fragments de quartz et de roches vertes, de taille centimétrique, indiquant la présence de brèches volcaniques. L’altération de ce matériau rocheux conduit à d’épaisses couches de sols brunifiés, argilisés, très riches en éléments grossiers, notamment au bas et à la mi – pente, avec comme caractéristiques morphologiques majeures: -la charge en éléments grossiers qui évolue inversement à la variation de la pente; -la faible humidité correspondant à une classe de drainage de faible indice; - le drainage, de moins en moins bon au fur et à mesure que l’on descend en profondeur dans le profil de sol; - le sol moins humide quand la pente est forte, et plus humide quand la texture devient plus fine. Mots-clés : cuirasses latéritiques; polygéniques, sols brunifiés, argilisés, mont Blanguand, Yaouré

Abstract: Introduction: Eclampsia is a common cause of maternal mortality in developing countries. The objective of this study is to evaluate the practice of anesthesia for eclampsia in tropical Africa. Patients and Methods: Retrospective descriptive study on the parturients who benefited from eclampsia anesthesia in the operating theaters of the gynecology and obstetrics department, the University Hospital Center (CHU) of Bouake over a two-year period (January 2015 to December 2016). The parameters studied were: anesthetic risk assessment, anesthetic management, immediate anesthetic and post-anesthetic accidents and incidents. Results: Out of a total of 3831 emergency cesarean sections, 65 were for eclampsia, or 1.69% of obstetrical surgical activity. The mean age of the patients was 20.30 ± 3.34 years (range: 14 years and 39 years). Prenatal consultation was not performed in 70% of cases and 85% of patients were primiparous. Patients classified as ASA IIIU accounted for 75% of the population and in 62% of cases, the Glasgow score was between 9 and 12. Induction was achieved with thiopental in 98% of patients and vecuronium was the only muscle relaxant used. The most common fetal complications were hypotrophy (50%), prematurity (30%) and respiratory distress (40%). Postoperative anesthetic complications were agitation (70%) and wake delay (15%). Maternal mortality was 5% and the neonatal death rate was around 7.69%. The elements of poor maternal prognosis were the ASA IVU class (P = 0.015) and the Aldrete awakening score between 3 and 5 awakening (P = 0.001). Conclusion: Anesthesia for eclampsia at CHU of Bouake is difficult. It needs to be improved thanks to better equipment of the health structures.

Abstract: A study on geological, geomorpholigical, pedological, hydrological and botanical prospection was undertaken. The main focus was to identify the types of rocks, relief, soils, river and flora which characterize a suitable landscape for the growth of Lippia multiflora. The results obtained from this first investigation indicate that Lippia multiflora needs a savannah type environmental ecosystem with sandy soils derived from silico-aluminous rocks preferably developed in medium or base of hill topographical positions.

Abstract: The conservation of cola nuts (Cola nitida) poses a real problem in Côte dIvoire because of the post-harvest losses. The objective of this study was to evaluate the impact of post-harvest technologies on organoleptic and physical properties of cola nut during storage. A biopesticide, glucose syrup and biopesticide + glucose syrup were applied to fresh cola nuts before conditioning and kept at 28°;C for 6 weeks. Physicochemical and sensory analyses were performed to check the quality of the nuts during storage. The results showed that the biopesticide keep cola nuts better than the others methods with only 11.66% ± 3.04% and 13.66% ± 3.95% of loss rates for white and red cola nuts respectively. Cola nuts treated with bio-pesticide retain significantly their freshness with 62.00% ± 1.15% of moisture for white nuts and 64.00% ± 2.00% of moisture for red nuts compared to those treated with glucose syrup and bio-pesticide + glucose syrup (56.66% ± 1.15%). Cola nuts treated with biopesticide have a better acceptability compared to those subjected to others treatments. The use of biopesticide for the storage of cola nuts minimizes the losses and maintains the quality whatever the type of cola.

Abstract: It is a rare clinical condition that may occur to two possible types: puerperal uterine inversion (IUP) and no puerperal uterine inversion (IUNP). Obstetrician will observe often only once in his professional practice. The risk of maternal mortality by hemorrhage is high. We report two cases of uterine inversion requiring a hysterectomy, including a postpartum mode and the other gynecological mode with young women. Hysterectomy remained a last resort treatment in the two types, to reduce morbidity. In the case of uterine inversion, the treatments without hysterectomy could be facilitated if the management is early and adequate. Furthermore, the support should be multidisciplinary and fast in the two types.
