Abstract

Anti-neutrophil cytoplasmic antibody (ANCA) are produced against lysozomal constituents and primary granules of myeloid cells (Neutrophiles & monocytes) in some rheumatic diseases and wegner’s granulomtosis (WG). This antibodies not only may related to onset of vasculitis lesions, but also have a valuable diagnostic tool, thus, first we tired to evaluated the prevalence of this antibodies in 65 serum of patients with RA and 42 serum of patients with SLE. By using of indirect immunoflourescence assay (IFA), two staining patterns are recognized: Cytoplasmic (C-ANCA) pattern which in 80% of results from anti-PR3, and prenuclear (P-ANCA) pattern, which can result from any antibody directed to myeloperoxidase (MPO), cathepsin G (CG) lactoferrin (LF), elastsae (HLE) and lysozyme (LZ). The sensitivity and specificity for SLE from 1:128 serum dilution was 8% and 85.1% respectively, and for RA from 1:16 dilution was 32.2% and 87.5% respectively. Of the 19 SLE, ANCA positive patients 18 (94.7%) had P-ANCA and 1 patient (5.3%) had C-ANCA and of the 23 RA, ANCA positive patients, 17 (73.9%) had P-ANCA and 6 patients (26.1%) had C-ANCA.

Abstract

In this study 32 patients whom had only one superficial bladder tumor (T?-T1 stage) were selected to investigate the effectiveness of either BCG of Alfa-Interferon in preventing the recurrence of tumor. The other aim of this study was to compare the ideal regiment for the patient. These patients previously had neither tumor nor immunotherapy. The patients were divided randomly into two groups, each consisting of 16 people, and they were given the chosen medicine two weeks after surgery of tumor, which is usually superficial tumor (TCC type). 10 million unit of Alfa-Interferon in amount of 7 dose was injected weekly in those patients in group 1 and 120 mg BCG in group 2 respectively. Tumor recurrence in those patients, which receive interferon, was 50% and those that receive BCG was 18.5% respectively (P=0.07). The average recurrence of tumor in group 1 was 0.046 for one person per month (Patient/month) and the same index for group 2 was 0.015 recurrence for each person per month. Relative risk in equal to 3 (Relative risk=3) with accuracy of 95% between (0.87-10.38) but in those patients that were under ?-Interferon treatment only 4, and in BCG group 13 patients got the side effects of medicines.

Abstract

Background & Objective: Approximately one-third of the world’s population is infected with Mycobacterium Tuberculosis (TB), which is a indicator of high distribution of these bacteria in our environment. The only vaccine currently available against TB is the attenuated Mycobacterium Bovis strain bacillus Calmette-Guerin (BCG), which used regularly for many years to prevent the Tuberculosis in Iran and many part of the world. The efficiency of this vaccine varies in different populations, and is a matter for discussion. On this basis, the present study has been set up to determine the level of Tuberculin reaction in 4.5 months and in 7 years old children that receive BCG vaccine at birth time, in Golestan province. Materials & Methods: 2700, 4.5 month infant and 2400, 7 years old children in Golestan province were chosen by cluster sampling after the proper permission from the parents, public health centers and educational authorities were taken. The presence of the BCG scar were assessed, and 0.1 ml of 5 tu Tuberculin were injected subcutaneously. The induration was measured 48-72 h after Tuberculin injection. The results were determined as present and compare with T-test. Results: In these study 2559 infants and 2193 child were taken part in the final evaluation. The BCG scar were present in 97.9% of infants and 87.8% of 7 years children, this difference was meaningful. The average induration in 4.5 months babies were 2.29 mm, and in 7 years child was 0.66 mm, this difference was significant (P<0.05). More than 44.7% of babies and 82% of 7 years children didn’t show any reaction after PPD test, this difference was also significant (P<0.05). Conclusion: The level of positive Tuberculin reaction in infants of this province in spite of vaccination was very low, and this level was reduced after 7 years time, this indicate that BCG vaccination at birth did not have any major role in positive Tuberculin reaction. Our results also indicate that the presence of scar can be a good indicator for previous vaccination. In regard to the negative Tuberculin reaction in majority of babies, it is suggested to evaluate the efficacy of BCG vaccine in preventing the TB disease itself, by other method such as studying the TB incidence among children in long term or by determination of cytokines level after Tuberculin injection.

Abstract

Atherosclerosis which is the result of cholesterol deposit in coronary arteries is the main cause of morbidity and mortality, worldwide. Reverse cholesterol transport (RCT) is a process that causes efflux of excess cholesterol in vessels layers and reduces the risk of atherosclerosis. Adenosine triphosphate (ATP) binding cassette transporters G5 and G8 (ABCG5 and ABCG8) are two membrane cholesterol transporters in hepatocytes and enterocytes that transport cholesterol into the bile and feces. Considering importance of ABCG5 and ABCG8 in RCT and prevention and treatment of coronary atherosclerosis, the aim of this review article was to study the ABCG5 and ABCG8 functions, the role of them in heart stroke prevention and the effects of exercise trainings on genes expression of these two substances. Atherosclerosis, exercise, physical activity, RCT, ABCG5 and ABCG8 were used keywords for searching of related articles between years 1990 to 2018 in google scholar, PubMed, Elsevier, Scopus, SID, science direct and ProQuest databases. 294 articles were found and after precise reading of them, 84 articles were selected for this review article. Overall, considering role of transcription factors LXR/RXR are responsible for regulation of genes involved in cholesterol efflux (ABCA1, ABCG1), cholesterol transport (lipoprotein lipase, CETP), cholesterol transformation to bile acids (CYP7A) and metabolism and excretion of cholesterol into bile or gut lumen, stimulation of them induces elevation of ABCG5 and ABCG8 genes expression. The effect of exercise on these factors is a novel subject that may increase our knowledge to prevention and treatment of atherosclerosis.
