چکیده برای بررسی اثر گیاه دارویی چویل بر چربی درون شکمی و عملکرد، 476 جوجه ی گوشتی سویه ی کاب 500 به طور تصادفی به 7 تیمار با 4 تکرار و 17 قطعه جوجه در هر تکرار تقسیم شدند. به جوجه ها جیره پایه یکسانی با 0 درصد (شاهد)، 4/0 و 8/0 درصد از پودر چویل در روزهای 1 تا 28، 29 تا 42 و 1 تا 42 روزگی، خورانده شد. نتایج بر عملکرد نشان داد که 4/0 و 8/0 درصد چویل به طور معنا داری خوراک مصرفی را کاهش داد (05...
multiple sclerosis (ms) is a chronic inflammatory disease that leads to degeneration of the brain and spinal tissue. imbalances of cd4+ t cells including thelper1 (th1)/thelper2 (th2) and thelper17 (th17)/tregulatory (treg), their secreted cytokines and gene expressions, are important aspects of in immunopathogenesis of ms. vitamin a and its metabolites can regulate the immune system and appear...
high cortisol level in endogenous cushing’s syndrome suppresses the immune system and after treatment there may be an over activity of immune reaction leading to autoimmune diseases mostly thyroid and rheumatologic disorders. this is the second reported case of multiple sclerosis developing after treatment of cushing’s syndrome. a 42-year old man is reported who presented with bone fracture and...
one of the most common outcomes of pulp inflammation is periapical granuloma formation. existence of immune cells in these lesions showed involvement of both humoral and cellular immunity in the site. the presence of different antigens in the root canal causes production o various antibodies and consequent immunological reactions. different theories have been proposed on periapical cysts. the m...

micrornas (mirnas) are small preserved non-coding rna molecules that regulate gene expression post-transcriptionally by targeting the 3' utr of mrnas for translational repression or degradation. the rising evidence has established the significant role of mirnas within the regulation of immune system and the prevention of autoimmunity. mir-146a has obtained an importance as a modulator of d...
the plant-pathogen interaction is a multifactor process that may lead to resistance or susceptible responses of plant to pathogens. during the arms race between plant and pathogens, various biochemical, molecular and physiological events are triggered in plant cells such as ros signaling, hormone activation and gene expression reprogramming. in plants, micrornas (mirnas) are key post-transcript...
objectives: the aim of the present study was to investigate immunotoxic effect of safranal (saf), a main component of crocus sativus essential oil, using balb/c mice. materials and methods: saf was administered intraperitoneally at doses of 0.1, 0.5 and 1 ml/kg for 3 weeks. hystopathological examination of spleen and bone marrow, cellularity of spleen, delayed type of hypersensitivity (dth) res...
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 examinati...
Corticosteroid drugs are used to treat many lesions and inflammatory conditions and immune-related diseases due to their anti-inflammatory effects and suppression of the immune system. These drugs, due to possible side effects such as adrenal insufficiency, should be prescribed with caution along with an assessment of its risk-benefit ratio. Moreover, its nutritional, discontinuation, and compl...
