Effect of plant growth promoting rhizobacterial (PGPR) inoculation on growth in tomato (Solanum Lycopersicum L.) and characterization for direct PGP abilities in Morocco

Plant Growth promoting rhizobacteria are a heterogeneous group of bacteria that can be found in the rhizosphere, at root surfaces and in association with roots. They benefit plants through Production of plant hormones, such as auxins, asymbiotic N2 fixation, solubilization of mineral phosphates, antagonism against phytopathogenic microorganisms by production of antibiotics, siderophroes, Chitinase and other nutrients ability to effectively colonize roots are responsible for plant growth promotion. An experiment was conducted in the field of National Institute of Agronomic Research of Meknes. Morocco. The experiment was a completely randomized design with six replicates. There were four treatments viz. T1: (control; N0 -PGPR), T2: (N0 +2027-2), T3: (N0 +2066-7) and T4: (N0+2025-1). The results indicated that a remarkable increase in root growth, namely length, the diameter of the rod and the total chlorophyll. A total of three different bacteria colonies were isolated and proceed with in vitro screening for plant growth promoting activities; phosphate solubilization, nitrogen fixation, indole acetic acid (IAA), ammonia production and antimicrobial enzymes (cellulose, chitinase and protease) activity. Among the three bacterial strains, all bacterial strains are able to produce ammonia, IAA production and nitrogen fixation activity, one strain phosphate solubilizing activity, two strain are able to produce cellulase syntheses, Protease activity and Chitinase activity

Physico-chemical study and quality control of some types of Moroccan honey

Honey is a very complex biological compound of great diversity, giving it a multitude of properties, both nutritionally and therapeutically. In order to determine the physico-chemical characteristics, three types of samples were collected from the region of Morocco. These are zandaz honey and black honey from the Bouyblane region, multi-flower honey from the Atlas region, and commercial honey called "Achefae". These honeys are analyzed for determination of pH, electrical conductivity, ash content, density, free acidity, hydroxymethylfurfural content, color intensity, and phenolic compounds. These physico-chemical parameters studied are the most frequently used as indicators of the quality and stability of honey and having a great influence on its organoleptic properties. The results showed that there were differences from one sample of honey to another and that they all meet international standards

LA CATARACTE CORTISONIQUE : A PROPOS DE 18 CAS

Les corticostéroïdes sont largement utilisés en ophtalmologie. Plusieurs voies d’administration sont possibles. Cependant leur utilisation chronique, locale ou générale est responsable d’effets secondaires multiples dont la cataracte cortisonique qui constitue la seconde complication oculaire après le glaucome cortisonique. Ces complications peuvent menacer le pronostic visuel, et devenir plus graves que la maladie initiale elle-même.A travers une étude rétrospective, portant sur 18 cas de cataractes cortisoniques, colligée au service d’ophtalmologie pédiatrique de l’hôpital 20Aout de Casablanca, nous décrivons le profil épidémiologique, clinique et thérapeutique de ce type de cataracte, en insistant sur l’intérêt de la lutte contre l’automédication par des corticoïdes, ainsi que de l’importance d’une prescription bien réfléchie et d’un suivi rigoureux
