this experiment was conducted to investigate the effects of four medicinal plants with antibacterial property on immune system and ileum bacteria population of broiler chicks.a total 336 day-old male ross broiler chicks were used in a crd design with 6 treatments and 4 replicates per each treatment. cuminum l, mentha piperita l, achillea l, teucrium polium l, in levels of 1.5, 0.3, 0.2 and 0.2 ...
background : ticks are blood feeder acarians that feed on variety of animals and introduce a wide variety of molecules to their host immune system and some of them may stimulate host immune system to produce antibodies. this study was carried out to detect humoral immune responses following boophilus annulatus infestation. methods: seven cattle were each experimentally infested with 10000 b. an...
Background: The stress is one of main factors effects on production system. Several factors (both genetic and environmental elements) regulate immune response to stress. Objectives: In order to determine the major immune system regulatory genes underlying stress responses, a learning Bayesian network approach for those regulatory genes was applied to RNA-...
In this paper, the urinary infection, that is a common symptom of the decline of the immune system, is discussed based on the well-known algorithms in machine learning, such as Bayesian networks in both Markov and tree structures. A large scale sampling has been executed to evaluate the performance of Bayesian network algorithm. A number of 4052 samples wereobtained from the database of the Tak...
This study was conducted to compare the effects of diets Borage Powder and control (no additives diets) on broiler’s average blood cell counts and immune system on the broiler chicks. Sixty four male broiler chicks (Ross 308) randomly allocated into one of two treatments with four replicates of eight chickens based on a completely randomized block design. Diets were include control (no additiv...
chronic hepatitis b is still a major public health issue despite the successful prophylactic vaccination attempts. chronicity of hepatitis b virus(hbv) is mainly due to its ability to debilitate host's immune system. therefore, major measures have been taken to stop this process and help patients with chronic hepatitis b infection recover from their illness. while satisfactory results have...
conclusion mature biofilms were found to be much more resistant to antifungal agents and the host immune system than free cells. the factors responsible for high resistance included the complex architecture of biofilms, ecm, increased expression of drug efflux pumps, and metabolic plasticity. objectives the present work investigated certain aspects of the resistance of c. albicans biofilms to d...
Paecilomyces Sp. are saprophytic fungi, which have rarely been pathogen for human. Herein, we report a case of cutaneous infection with Paecilomyces lilacinus with unusual presentations in a healthy young woman. A biopsy provided an initial diagnosis of fungal elements in the tissue. Multiple positive fungal cultures were obtained from the biopsied tissue. Microscopic and macroscopic examinatio...

Objective. To study the effect of immunomodulators on learning and memory and on cholinergic receptor sensitivity. Methods. Animals were initially treated for a period of 8 days with cyclosporine/levamisole/saline. They were then subjected to passive avoidance training and 48 hrs later, the retention test for the passive avoidance task was conducted. Twenty-four hours after the retention tests ...
