L'estomac est exposé à divers xénobiotiques qui provoquent des effets variables en fonction de leur nature chimique. Nous avons exposé l’estomac à une solution d’éthanol afin étudier les propriétés thérapeutiques de l'extrait brut méthanolique des racines de la plante Centaurea fragilis contre l’inflammation gastrique. Cet extrait a été analysé par diverses techniques pour évaluer ses teneurs en polyphénols et flavonoÏ des, en particulier, par chromatographie en phase gazeuse et le test du pouvoir antioxydant. L’effet de l’extrait brutmétanolique sur l’état d’inflammation gastrique induit par l’éthanol à raison de 10ml/kg a été évaluée. Nous avons constaté une augmentation du malonyl dialdéhy de (MDA) et une déplétion de glutathion (GSH). Nous avons conclu que l’ extrait, administré à raison de 200 mg/kg possédait des activités anti-inflammatoire et antioxydante très intéressantes.

Une étude du parasitisme interne a été réalisée chez les bovins naturellement infestésdans une région Basse Kabylie.Des coproscopies (n=143) effectuées pendant 7 mois, de décembre 2013 à juin 2014, ontrévélé un taux global d'infestation de 63,22%. Cette étude a montrée une prédominancefaunistique des genres: nématodes (strongles digestifs 30,32 %, Toxocara vitulorum 6,45 % etStrongyloïdes papillosus 1,29 %), de trématodes (Fasciola hepatica 12,25 % etParamphistomum daubneyi 1,93%), de coccidies (43,84 %) et de cestodes (Moniezia expansa1,93 %). La coccidiose a été distinguée comme parasitose majeur suivie des strongylosesdigestives et de la fasciolose. Les autres parasitoses ont été considérées moins importance.L‘intensité parasitaires et les excrétions d'oeuf par gramme étaient faibles (< 450 OPG).

The current study was conducted to investigate the role of some aspects of immunogenetics that related with arthritis disease. The study includes 100 blood samples were collected from people who attend to Marjan hospital, with 25 samples from apparently healthy people during the period of October 2015 to March 2016. Immunological study involved estimate the levels of IL-18, IL-4 in certain arthritis patients using ELISA technique, the estimation of IL-18 revealed significantly increased in all patients by contrast with control group with mean value 133.93 pg/ml in rheumatoid arthritis (RA) patients and 103.3 pg/ml for osteoarthritis (OA) patients (P < 0.01). Estimation of IL-4 and contrary results showed increasing IL-4 levels in both types of arthritis with mean value (45.06 pg/ml, 33 pg/ml) with RA and OA respectively compared with control group (22.48 pg/ml) with P ≤ 0.01. The genetic study involved screening of IL-18 (-137 G/C) and IL-4 (-590 C/T) related with arthritis patients for 75 samples including patients and control using PCR-SSP technique. The SNP of IL-18 (-137 G/C) showed: GC heterozygous with (39), GG homozygous with (21) and CC homozygous with (15). The allelic and genotypes association appeared no significant differences between patients and control groups. Another SNP of IL-4 (-590 C/T) showed: CT heterozygous with (50), CC homozygous with (9) and TT homozygous with (16). The allelic and genotypes association showed no significant differences between patients and control groups. The possibility of detection of histocompatibility antigens HLA (DRB1 & DQB1) alleles related genetically with disease by using (PCR-SSP) was performed and showed that no significant differences between RA patients with DRB1 (0301 & 0701) and DQB1 (0201) alleles compared with control, while in osteoarthritis patients showed significant differences between patients with DQB1 (0201) allele compared with control, but no significant differences with DRB1 alleles.

School is a fundamental socialization context for individuals. It is as an institution intended to prepare individuals for life and adulthood and make them intellectually reflexive. Since this great institutions know various problems that hid their role in building future citizens,in this dissertation we present one of the serious problems that destroy our schools today that is Violence. This work aims at raising attention to this phenomenon and the most important is to propose some solutions to reduce it. The objective of this study, is toconstruct a clear definitions to Violence and School Violence and analyses its origin in the human being using different explanatory theories, determines the main interrelated factors that lead the learners implicate themselves in antisocial behaviours, presents its forms and highlight its negative effects in teaching and learning and finally suggests some strategies and practices for intervention. Through our objective we suggest some hypotheses: first violence exists in our high schools and takes different forms then, it has negative effects on teaching and learning and decreases our schools’ effectiveness and finally since the violent incidents inside our schools are really increased we hypothesise that there is no serious work for prevention. To achieve the aforementioned objective we should use data gathering tools which are two questionnaires one for teachers and the other one for students. Thus, we work on this tool to examine the teachers and students feedback. The research findings go hand by hand with our hypotheses which emphasize that violence exists in our high schools, impact teaching and learning process and preventions have to take place to reduce it.
