Traditional medicine still remains the main recourse of the majority of populations in developing countries. This medicine uses substances of animal, mineral and especially vegetable origin. Medicinal plants have always been part of the daily life of man since he uses them to feed himself, to cure himself and sometimes in his religious rites. Different traditional plants are used in the treatment of cardiovascular diseases such as hypercholesterolemia, atherosclerosis, hypertension and their associated factors (diabetes, obesity, etc.). The roots and leaves of these plants are used in herbal tea in the treatment of these diseases. Traditional medicine, which is based on traditional knowledge, deserves to be promoted. This valorization requires the availability of improved traditional medicines, that is to say effective, with proven safety and with precise posology. This study is made on the effect of some medicinal plants on some cardiovascular diseases, liver diseases, and cholesterol in the blood as well as the blood pressure. On the other hand a kind of general description on some cardiovascular diseases; hypercholesterolemia and arterial hypertension, as well as the risk factors like obesity, we quote some medicinal plants indicated against these diseases.
Mercury chloride is one of the most dangerous metals for health due to its volatility and its rapidity to pass through the human body. We undertook this study with the aim of investigating the detoxification of mercury chloride by the Calotropis procera plant taken from the Algerian Sahara. In this study, the toxicity of mercury chloride affected the kidney weights of male and female rats through increased weight. On the other hand, the plant Calotropis procera demonstrated a beneficial effect by restoring the weight of the kidneys. The results of this study demonstrated that the plant Calotropis procera. procera has a beneficial effect on the liver, which was able to restore its weight affected by the mercury chloride. Treatment of male and female rats with mercury chloride has also been found to lower blood urea levels, uric acid, proteins total, alkaline phosphatase and direct, indirect, total bilirubin levels. This toxicant caused an increase in blood sugar levels, blood creatinine, in male and female rats. Our results demonstrated no effect of mercury chloride and of the plant on cholesterol levels and triglycerides in female rats. No change in albumin levels was found in male and female rats. However, mercury chloride was found to increase cholesterol and triglyceride levels in male rats. The Calotropis procera plant restored cholesterol and triglycerides in male rats. This study can help to clarify that the detoxification of mercury chloride by Calotropis procera act directly on liver and kidney by ameliorating uric acid, blood sugar, creatinine, albumin, alkaline phosphatase, urea, total protein.
Cleome arabica is a spontaneous plant in arid zones, toxic and has hallucinogenic effects. In this work, we seek to evaluate the direct and delayed effect of the aqueous extracts on the vinegar fly Dorsophila melanogaster, laboratory model par excellence. Treatment is by ingestion on second instar larvae (L2). The results show that mortality rates can reach 90% after 15 days of treatment as we recorded a disturbance of fly development. Observation of sexual behavior in treatment-emergent adults indicates that C. arabica acts negatively on the course of the different sequences leading to mating in Drosophila.
Our study area is a transect that connects the wilaya of Souk-Ahras and the wilaya of Tebessa where it is formed by a mountainous massif site that includes a very important vegetal diversity. This area is located in the North East of Algeria where it prevails a Mediterranean climate, characterized by a temperature gradient that increases from North to South, whose average annual rainfall evolves in the opposite direction of the temperature. To identify the diversity of soils in this region we made a qualitative characterization of soils that integrate the axis between the north and south of the wilaya of Souk-Ahras and Tebessa, we chose six stations representative of the area in question, several physico-chemical parameters were studied such as, the granulometry, hydrogen potential, electrical conductivity, hygroscopic moisture, organic matter and total limestone to define and enhance the quality and richness of the soil of this region. The physicochemical characterization reveals a diversity of the nature and quality of soils in this mountainous region, and an adequacy between the soil, the climatic environment and the type of plant cover whatever the region.
Water plays a crucial role in the life and development of humanity. Since time immemorial, people have settled near water points, which have always been a source of life and well-being. For thousands of years, it has been celebrated and recognized as a sacred resource. Today, due to rapid population growth, economic development and other challenges that affect natural resources, water has become a precious commodity. To this end, the objective of our work is to know the chemism of the groundwater of the lower valley of Oued Bounamoussa Willaya of El Tarf (North East Algeria) and to diagnose the origin and intensity of the pollution that degrades this water resource. A sampling of water was carried out in February 2021 on all the length of Oued Bounamoussa (Upstream, Center and Downstream), of which several physico-chemical parameters were carried out such as; pH, EC, SS, NO-3, NO-2, Cl-, P2O5. The results obtained show the presence of a very important pollution rate in the groundwater of Oued Bounamoussa, which pollution has several origins namely urban, agricultural and industrial. So this water resource has become a danger and risk on the health of living beings and on the intoxication and it disturbs the sustainable development.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
