Abstract
Levamizole hydrochloride (C11H12 N2 S.HCl) is a drug capable of being rapidly absorbed from the gastrointestinal tract and is also rapidly eliminated from plasma. It has a modulating effect on the immunesystem, and may be used in treatment of parasitic diseases and infections. Because of its toxicity to liver and its rapid clearance from plasma, this drug must be formulated in such a way so as to decrease its necessary dosage and thus its toxic effect on the liver while improving or at least maintaining its present tolerance to disintegrating factors in the surrounding and its ability to efficiently reach its target tissues (the immune system). Therefore, the liposomal form of levamizole hydrochloride can be helpful in achieving the stated goals. In this study, first a preparation of a multilayer liposome with hydrophilic coating was done. For this purpose, a mixture of phosphate buffer (soudium and potassium phosphate I, 4 mmol, pH =7.4) ethanol and lipid (100 mg phosphatidyl choline, extracted from soya) was used (buffer 200 mg, ethanol 80 mg, lipid 100 mg). Also levamizole hydrochloride with half a solubility in water was used. The above solutions from levamizole containing liposomes under a few cycles of freeze-thawing method (20-60°C). Ultracentrifugation (45 min, 60.000 rpm) was used to determining the extent of drug encapsulation in this method we can calculate the percent encapsulation using a control. In our method this percentage was calculated to be 92.7%.

Abstract
Dorsal traumatic dislocation of metatarsophalangeal joint of great toe is a rare injury. Ability to reduce the dislocation by nonoperative measures depends largely on the type of dislocation and involvement of the sesamoid complex. There are three basic types of dislocations. Type I cases are usually irreducible on closed reduction, the metatarsal head being incarcerated by the conjoined tendons with their intact sesamoids. In type II, the sesamoid complex disruption usually pemits closed reduction. We present an irreducible dislocation of the first metatarsophalangeal joint with fibular sesamoid fracture in an 80-year-old man. In addition, he had a concomitant dorsal dislocation of the second MTP of the same foot, to our knowledge only one case with this injury was reported in the literature.

Abstract
Background: Osteoid osteoma is a well-known benign tumor of bone. It occurs in children and young adults and is rarely seen above the age of 40. It is uncommon in hand and wrist. If it occurs in hand and wrist, its diagnosis is difficult because of its unusual presentations both clinically and radiologically.
Materials and Methods: We encountered ten patients with osteoid osteoma of hand during the last ten years in orthopedic department of Emam university hospital from 1970 to 1979.
Results: The average age of ten patients with osteoid osteoma of the hand and wrist that were treated in Imam hospital from 1369 to 1378, was 22.9 years (range, 14 to 33 years). Five lesions were in proximal phalanx, one in middle phalanx, and one in distal phalanx. In the wrist, one lesion was in the capitate, one in the lunate, and one in the hamate. The average time from onset of symptoms to successful treatment was 20 months (range, 4 months to 60 months). Three of ten patients had had treatment elsewhere, all of them had had unsuccessful operative procedures related to incorrect diagnosis. All patients had a minimum follow-up of 6 months (range, 6 months to 9 years, mean: 4.6 years). The operative treatment were successful in all ten patients without any signs or symptoms of recurrence. Only limitation of proximal interphalangeal joint range of motion was remained in one patient due to 60 months delay in diagnosis and treatment.
Conclusion: High index of suspicion is necessary for diagnosis of osteoid osteoma of hand because of unusual presentation of it. The most important factors for successful treatment of osteoid osteoma of hand are accurate diagnosis and exact preoperative planning.

Abstract
Background: Asthma is a major health condition in Iran. This randomized clinical trial was aimed for the comparison of the effects of two exercise protocols (aerobic and aerobic-strength) on the pulmonary indices and quality of life of asthmatic patients.
Methods: The study was conducted in pulmonary ward of Dr Shariati Hospital in Tehran, and Research Center of Exercise Medicine of Tehran in 2009. Fifty six asthmatic patients were selected and after two weeks of education, their spirometric parameters were recorded and the St George's respiratory questionnaire was completed. Then patients were randomly assigned to two groups of A and B. For ten weeks group A did the aerobic-strength exercises and group B did only the aerobic ones at home. At the end, again their spirometric parameters were recorded and the questionnaire was completed. Finally 42 patients completed the study.
Results: After the intervention, FEV1 and FVC but not FEV1/FVC increased in group A. There were no changes in these parameters in group B. In addition, post-intervention FEV1 and FVC were significantly higher in group A than group B. All scores of St George's respiratory questionnaire were significantly improved in both groups but they were not different between them.
Conclusions: Our findings showed that regular aerobic exercises, individually or concomitant with strength exercises, could improve vital signs and quality of life of mild to moderate asthmatic patients. However, only aerobic exercises with strength ones improve spirometric parameters. Therefore, a combination of both aerobic and strength exercises could be considered in treatment protocols of asthmatic patients.

Abstract
Background: Radioactive synoviorthesis by injection of safe radioisotopes into the joints affected to chronic arthritis is accounted as a novel method to treat haemophilic arthropathy. The main goal of this therapy would be decrease in frequency of hemarthrosis and consumption of coagulation factors. In this study we assessed the effect of radioactive synoviorthesis on the frequency of hemarthrosis, factor consumption and other related parameters.
Methods: In an interventional study in Imam Khomeini Hospital in Tehran, Iran, after meeting of inclusion criteria and taking written consent, colloid 32p radiosynovectomy was performed for 56 joints with haemophilic arthropathy. After local anesthesia of injection site, one mci of 32P for large joints (knee) and 0.5 mci for small joints (ankle and elbow) was injected, respectively. Half of these doses were considered for children (age <12 years).
Results: The mean of age was 16.78 year old (Range: 2.5-36 SD: 7.46) and 98.2% of cases were male. Injected were knee 80.35%, ankle 12.5%, and elbow 7%. The mean of follow-up was 43.63 months (range: 3-102) that at the end, the result was 62% decrease in frequency of hemarthrosis (p=0.0001) and 84% decrease in factor consumption (p=0.0001). However, the involvement of other (non injected) joints during follow-up could lower the decrease of mean of total factor consumption.
Conclusions: Radioactive synoviorthesis can be a cost-effective alternative to decrease hemarthrosis and factor consumption in haemophilic arthropathy.
