Leishmaniasis is a protozoal disease that transfer to human by phlebotomus with leishman body. It is a chronic disease that infects skin, mucosa and viscera. Cutaneous form is common in Iran but visceral form is endemic in Kordestan, Lorestan and Khozestan. It is a case report of visceral type of leishmaniasis from Lorestan. His disease onset was fever, bloody diarrhea and cough, that s...
multiple technological levels the necessity of developing vaccine quality control systems is one of the requirements of our country Coordinated tests of the absence of externous agents in biological substances are considered as a major international concern for veterinary vaccines. Exogenous agents such as Newcastle disease virus, avian leukosis virus, infectious laryngotracheitis virus (ILTV)...
Dogs in which livers have been replaced with hepatic homografts usually die in 5 to 10 days. Liver metabolism is not detectably abnormal at first, but gradual deterioration of function commences on the fourth or fifth day. There was histologic evidence of rejection in all dogs dying after 4 days. This ranged from minimal mononuclear infiltration to almost complete destruction of parenchyma. In ...
Gamma globulin was demonstrated by immunocytochemical fluorescence technique in many reticuloendothelial cells of the hepatic sinusoids and of the fibrous tracts in various forms of hepatitis and in postnecrotic cirrhosis. In other liver diseases and in normal livers, even in the presence of hypergammaglobulinemia, few if any gamma globulin-containing cells were found. In contrast, spleen and l...
Adult humans have about 25 trillion red blood cells (RBCs), and each second we recycle about 5 million RBCs by erythrophagocytosis (EP) in macrophages of the reticuloendothelial system. Despite the central role for EP in mammalian iron metabolism, the molecules and pathways responsible for heme trafficking during EP remain unknown. Here, we show that the mammalian homolog of HRG1, a transmembra...
In this study, we used Random Amplified Polymorphic DNA (RAPD) for identification of 17 isolates of Leishmania from the skin and reticuloendothelial system of humans, animal reservoirs (rodent and dog) and sandflies in various parts of Iran in the last decade. Fifteen species have been confirmed by isoenzyme characterization by the London School of Hygiene and Tropical Medicine and Shiraz ...
Circulating immune complexes were found in 15 of 16 patients with fulminant hepatic failure due to viral hepatitis and all of six patients who had had halothane anaesthesia; however, they were found in only five of 32 patients with paracetamol-induced hepatic necrosis. The levels of circulating immune complexes were not related to the severity of the clinical course, development of renal failur...
The reticuloendothelial system includes macrophages and endothelial cells. These cells are produced and destroyed in vivo with a precision that implies the existence of homeostatic mechanisms. The stimuli for endothelial cell proliferation and monocyte production are becoming well characterized. However, the mechanisms involved in eliminating these cells are poorly understood. One mechanism inv...
A patient with rheumatoid arthritis developed severe exacerbation of symptoms 18 hours after an injection of gold thiomalate (sodium aurothiomalate). Immune complexes were present in his serum and synovial fluid; in the synovial fluid they were associated with intense complement activation. The effect of gold salts on splenic reticuloendothelial function was determined by measuring the clearanc...
