Background and purpose: Morphine vaccine is a product of morphine-6- succinate synthesis and its conjugation with albumin serum. Each dose contains 0.5 mg Aluminum hydroxide, 8 mg sodium chloride, 1.12 mg di- sodium hydrogen phosphate, 1.1 mg sodium di- hydrogen phosphate and 50 mg morphine-6- succinate albumin serum. Humoral safety is achieved in morphine addicts following three successive doses within 0-30- 60-day intervals. Its immunogenicity brings about withdrawal without the risk of abstinence syndrome. This study was conducted to examine the effect morphine vaccine on morphine addicts.
Methods and Materials: Based on the Ethics protocol of Pasteur Institute of Iran, this clinical trial was conducted on 102 male volunteer addicts (mean age 25 years). Variables included vaccine dosage and concentration on of antibodies. Volunteers were divided into groups of 30 (experimental) and 4 (placebo).
Adjuant was injected to placebo group addicts; the three experimental groups were given 5, 12, 100 and 600 mg within 0- 30-60 days interval through injection to deltoid; all subjects referred for follow-up on the 90th day. Blood samples and antibody evaluation was obtained from all three groups in months 5, 7, 9, 11 and 12.
Results: A positive correlation was observed between antibody production and vaccine dosage as well as frequency of injection.
Anti-morphine antibody was detected after the first injection of 100mg/ml, 600mg/ml and second injection of 12.5mg/ml doses.
Antibody levels reached the peak by three months and did not decline to the baseline after one year
Conclusion: the vaccine was well tolerated and lacked the reverse and unfavorable effects, characteristic of vaccines and drugs. On day 90, humoral immunity was created in all patients.

Background and Purpose: Although it is now certain that insulin injection allows us to control the complications resulting from blood sugar imbalances, its accurate control by insulin injection is difficult. Therefore as a logical solution, transplantation of islet cells is globally considered as a treatment and the present study is conducted to verify it.
Methods and Materials: After materials preparation, donor tissue was obtained from 6 male wistar rate cage 75-90 days (weight 250-300 gram). Transplantation was done on diabetic rate induced 2-4 weeks earlier by 60 mg/kg streptozotocin intravenous injection.
Results: After islet cells transplantation, blood glucose was reduced to normal (145±5 mg/dl) and insulin and C-peptide increased (1.9±0.1 MIU/L and 0.053±0.001 mg/ml respectively). Clinical symptoms of dibetes induction were relieved after transplantation.
Conclusion: The technique of islet cells transplantation in the form of encapsulation with the absence of immunological inhibitors to support the graft against the recipient's immunity system is an innovative method to treat type I diabetes.

Background and Purpose: It is thought that transplantation of islet cells would cure diabetic patients in world. Islet cells transplantation in people suffering from diabetes is of technical interest. A standardized procedure was developed for the preparation of rat islet cell grafts for purification of islet cells.
Materials and methods: In this process, after collagens digestion of pancreases, islets were isolated and dissociated, then with enzymatic procedure by DNase and trypsin, the islet cells changed in to single cells and these cells were assayed by flow cytometery.
Results: Flow cytometery of these cells indicated that there were 91% of beta cells in cell suspension. Most of the exocrine particles were lost during digestion.
Conclusion: Purified endocrine islet cell grafts were prepared by pure beta-cells, with or without endocrine non-beta cells. The purified aggregates were devoid of non-endocrine cells and damaged cells.
