The purpose of this study is to compare the results of chemical analysis of two types of activated from the pyrolysis of bull horn and that of cow. Six samples were used to measure pH, carbon, calcium and to determine adsorbent power. The pH was measured at a temperature of 20˚C using an “ANION 7010 ionomer” pH meter, the carbon (C) content was analyzed using a “EURO EA 3000” analyzer. and the electronic balance: “Sartorius CP-2P”, calcium (Ca) was analyzed using a DFS-8 spectrograph. For the adsorbency test, the 0.15% methylene blue R solution was used. At the end of this study, we found that the activated carbon from the bull horn demonstrated a carbon content that is higher than that of the cow horn (20.79% against 15.63%), activated carbon of cow horn is richer in calcium than that of bull horn (16.27% against 3.69%) and then the pH. The cow horn is higher than that of the bull horn (7.43 versus 6.5). For the adsorbent power, the sample (75% bull horn and 25% cow horn) was recorded with the greatest adsorbent power. Thus, from this study, it can be recommended as an activated carbon antidote to be used for poisonings treatment.

The present work was initiated for searching and evaluating the total heavy metal content in some selected local resources used by traditional healers in locally made antidotes to search for their toxicity. Elekat public slaughterhouse in the city of Bukavu, the central market of Kadutu and in the Ruzizi plain, precisely in Sange city, have been the purchased centers. The samples of bull and cow horns, oil palm nut shells, cow bones, ginger, black pepper and Mwenga salt were used. The spectrometric method has been used to carry out heavy metal content in each local resource using the atomic absorption spectrometer (VARIAN 1275). The heavy metals found and their average content are as follows: copper (Cu: 124.79 mg/kg), lead (Pb: 76.41 mg/kg), chromium (Cr: 33.9 mg/kg), zinc (Zn: 190.86 mg/kg), Arsenic (As: 107.41 mg/kg) and cadmium (Cd: 0.05 mg/kg). The averages of total heavy metal contents for all samples are below the standard of each one. The determination of the heavy metal contents in these samples allows evaluating human intoxication risk. These results show that antidote technology can be run without any toxicity risk and showed statistically significant differences compared to the controls (p 0.05) for chromium, zinc and cadmium have been recorded. However, most of the heavy metals molecules being thioloprives and then bioccumulatives, antidotes made from them shall not be consumed during a long period.

Introduction: Among the hypertensive pathologies of pregnancy, preeclampsia remains the entity responsible for pregnancy complications. Objective: The aim of this work was to determine the frequency of hypertensive pathologies in the peripartum, to determine the maternal and neonatal morbidity factors associated with preeclampsia on the one hand, and on the other hand, to other forms of hypertension in the peripartal period. Patients and methods: This is a cross-sectional study of hypertensive pathologies in per partum over a period of 15 months?which have been included any pregnant, parturient and hypertensive childbirth. The data was analyzed using SPSS software version 21.0. Data positioning and dispersion parameters were studied. The factor analysis?was?performed by determining the odds ratio with a 95% confidence interval and a significance level set at p?≤ 0.05. Results: 142 cases of hypertension were collected from a total of 2988 deliveries,?i.e.?a frequency of hypertension of 4.8%. The main form of high blood pressure (HBP) was the isolated HBP at 51.4%. 60.3% of primiparas were preeclamptic [OR 2.47 (CI 1.25 - 4.91)], 63.2% of preeclampsia did not follow prenatal consultations?[OR 2.43 (CI 1.06 - 5.62)], 63.6% of preeclampsia had moderate and severe threat premature delivery [OR 4.57 (CI 2.11?-?9.99)], neonatal hypoxia in the fifth minute was found in 34.4% of newborns of preeclamptic mothers [OR 3.02 (CI 1.44?-?6.34)], hypotrophy was observed in 41.4% of the cases in the preeclamptic patients [OR 5.41 (IC 1, from 55 to 19.57)]. Conclusion: Preeclampsia is significantly associated with maternal and neonatal morbidity.
