Abstract
Thrombotic thrombocytopenic purpura is the result of multiple thrombus disseminated in small arterioles throughout the body. Principle damage is in the endothelium of small vessels and capillaries. From 1982 to 1999, 28 patients (16 female and 12 male) have been treated for TTP. The outcome was evaluated for risk factors and prognosis. These patients were 18 to 69 years old. All had neurological sings, fever, microangiopathic hemolytic anemia and thrombocytopenia. These patients did not have predisposing factors. All patients were negative for hepatitis C and B. Plasmaphoresis was the main treatment in all and was done. The patients had plasmaphoresis from 1.5 to 6 liters per day. Minimum requirement was 4.5 liters to 95 liters in all. Replacement was fresh frozen plasma in 16 patients. 12 patient had FFP and cryopoor plasma half-and-half for replacement. 22 patients completed the treatment and became well 6 patients died. Chronic head ache and progressive dementia was observed in 2 patients. 6 patients did not recover and died. Platelets count over 100000/mm LDH lower than 500 units and disappearance of neurological disturbance was the end point of treatment. This study showed the good result of plasmaphoresis in TTP ad graves outcome in patient with cerebral bleeding, cardiopulmonary failure, prolonged QT in EKG, hypotension, and increased CPK. We did not observe any chronic cases in these groups. The cause of death were cerebral hemorrhage in 2 respiratory failure in 3 patients. One of the these patients had adult respiratory distress syndrome and pneumonia in another patient.

Abstract
The diabetes is an autoimmune disease, in which the role of autoantibodies is of a specific importance. The appearance of these autoantibodies can be the first symptom in the serum of type I diabetic patients, which may appear ten years before onset of the disease. The most important autoantibodies include Glutamic acid decarboxylase autoantibodies (GAD65-Ab). This can be used as a good tool for prediction in screening tests in type I diabetic patients. In the present study with prosedure RIA, we investigated the level of GAD65-Ab in patients with diabetes type I and their close relatives, and compared them with healthy persons. From the type I diabetic patients who have been suffering from the disease for periods of one week to twenty years, 63.3% of them had positive Anti-GAD65. This ratio was 8% in their close trelatives, and 0% in healthy persons. The difference in Anti-GAD65 between the healthy persons and close relative of patients was significant. This test may be employed in diabetes type I, as a screening test, and confirms the results of studies which have been conducted so far outside this country.

Abstract
Many studies have shown the clinical importance of CD7 expression in AML patients. To evaluate the clinical importance and response to chemotherapy in CD7 positive AML, this study was conducted. From the patients, 76 cases were studied during 3 years. In 3 years of this study 70.5 percent of CD7 positive and 89.6 percent of CD7 negative patients achieved complete remission with no significant difference between these two groups (P=0.11). We concluded that despite no importance of expression of this antigen in our patients, prevalence of CD7 positive cases in our study in higher than similar studies done abroad (52.6 percent versus 30 percent). It seems in respect of small number of our patients for evaluation of clinical and laboratory properties, larger study is needed.
