[ 1 ] - Expression of IGF-1, IL-27 and IL-35 Receptors in Adjuvant Induced Rheumatoid Arthritis Model

Background: IGF-1 and certain other cytokines have been shown to exert inflammatory/anti-inflammatory roles in chronic joint diseases. Objective: To assess the effect of IGF-1, IL-27 and IL-35, their interaction and their receptor expression in a rheumatoid arthritis model. Methods: Freund’s adjuvant-induced chronic joint inflammation was operated on 160 male rats. Animals were divided into his...

[ 2 ] - High Expression of Sphingosine Kinase 1 in Estrogen and Progesterone Receptors-Negative Breast Cancer

Background & objective: Breast cancer is the leading cause of cancer related death in females. Sphingosine kinase 1 (SPHK1) and its product sphingosine-1-phosphate (S1P) are the essential key regulator molecules in breast cancer through their ability to promote cell proliferation, angiogenesis, cell proliferation, and lymphagiogenesis. SPHK1 i...

[ 3 ] - Possible Interrelationship of Inflammatory Cells in Dry Type Cutaneous leishmaniasis

Background & Objective: There is a complicated interaction between leishmaniasis and the host immune cells, and also between the host immune cells. These interactions have fundamental effects on the outcome of the disease. The current study aimed at characterizing the number, distribution, co-localization, and interrelation of 4 types of inflamma...

[ 4 ] - Spinal Intradural Extramedulary Capillary Hemangioma Mimicking Meningioma

Hemangiomas are considered as vascular malformations which are categorized by the type of vascular channel to capillary, cavernous, venous or arteriovenous(1). Their usual locations are soft tissue , cutaneous or subcutaneous tissue and bone especially vertebra(2).However, intradural extramedullary hemangiomas are rare and most of them fall in cavernous type category. Hereby, authors report a w...

[ 5 ] - Maspin Gene Expression in Invasive Ductal Carcinoma of Breast

Background: The breast cancer is the most prevalent cancer among women, on the other hand absence of myoepithelial cells play a pivotal role in pathogenesis of this cancer. Thus we aimed to investigate the possible abilities of the molecular assay technique to find a relationship between mammary serine protease inhibitor (Maspin) gene expression possibly secreted by my...

[ 6 ] - Localized Leishmania Lymphadenitis Etiologic Agent Identified as Leishmania tropica Using Gene Sequencing

Leishmaniasis include several clinical manifestations, mostly cutaneous, visceral and mucosal (1, 2). Various species can lead to diverse clinical presentations. Thus species identification contribute to proper management (3). Localized Leishmania Lymphadenitis (LLL) is a distinct entity in clinicopathologic field presenting with isolated lymphadenitis and possible cocomitant cutaneous...

[ 7 ] - Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

[ 8 ] - DNA Load Analysis Using Real Time PCR In Comparison With Immunohistochemical Findings of Dry Type Cutaneous Leishmaniasis; Before and After Treatment by Imiquimode,Glucantime and Combination of Both Drugs

Background and Objectives: Kerman Province, especially city of Bam in the southeast part of Iran, is epidemics for dry type cutaneous leishmaniasis (DTCL). This study was conducted to compare the effect of different treatments on parasite DNA load following therapies using Real-Time PCR method. Materials and Methods: Fifteen patients were divided into three groups under therapy with intralesio...

[ 9 ] - Evaluation of Possible Role of Dendritic Cells in Various Lupus Nephritis

Background & Objectives: Chronicity of lupus nephritis (LN) should be considered for interaction of cell mediated immunity (CMI) and dendritic cells in glomeruli and tubulointerstitial areas. In this study establishment of immunohistopathological changes of dendritic cells and other immune effector cells in lupus nephritis comparing with non-lupus nephritis was performed. Materials & Methods: ...

[ 10 ] - Hidden Fetus in Fetu in a Male Adult

We present unusual retained remnants of hidden conjoined twin of possible abdominal pagus after 21 years who presented with abdomenpain and incidentally have found his forbidden conjoined twin. He presented for many years with a palpable epigastric mass, and recent abdominal pain, early satiety, nausea and vomiting. The mass was a like deformed fetus weighing 815 gr who was anencephalic and dep...

[ 11 ] - Infantile Inflammatory Myofibroblastic Tumor with Terminal Ileum Obstruction

Inflammatory myofibroblastic tumor is an uncommon benign neoplasm and its presentation in small bowel is rare. Due to clinical manifestation, laboratory data and radiologic results, there is an increased risk of over diagnosis as malignant tumors particularly malignant lymphoma in childhood therefore may be resulting in wrong therapeutic approach. However pathologic findings could be demonstrat...

[ 12 ] - Kimura’s Disease: A Case Report and Review of Literatures

Kimura’s disease (KD) is a chronic inflammatory disorder primarily seen in male Asians during the second and third decades of life. Clinically, it presents as solitary or multiple subcutaneous nodules, predominantly in the head and neck region, typically in the pre auricular region, forehead, and scalp. The etiology of Kimura disease is still unknown. This disorder should be suspected when the ...

[ 13 ] - Localized Leishmania Lymphadenitis: A Morphologic and Immunohistochemical Study

Localized Leishmania Lymphadenitis (L.L.L) is a self limited clinical presentation of cutaneous leishmaniasis. Microscopic findings in L.L.L are very similar to Toxoplasma lymphasenitis. In all cases, an intensive microscopic search should be done for Leishman bodies. In this study, we describe our micro...

[ 14 ] - Histopathological changes of the antigen-induced chronic arthritis in the knee joint of the rabbit

Background and Objectives: The cause and pathophysiology of rheumatoid arthritis has not been fully understood and an experimental model of this disease is essential for research on the problem. In this research study, establishment and histopathological changes of chronic arthritis due to intra-articula...

[ 15 ] - Application and Assessment of Allogeneic Fibroblasts for Cell Therapy

Background and Objective: In recent years, due to increasing number of patients with non-healing skin ulcers, skin substitutes have been used. Skin substitutes contain living cells causing faster and more effective wound healing. Therefore, research on the use of autologous and allogeneic cells such as fibroblasts in skin substitutes has attracted attentions. However, there are...

[ 16 ] - Peripheral Blood-Derived Mesenchymal Stem Cells: Growth Factor-Free Isolation, Molecular Characterization and Differentiation
