Background and Objective: Zoonotic Cutaneous Leishmaniasis (ZCL) is a parasitic disease which caused by a protozoan belongs to the genus Leishmania. ZCL is of great public health importance in many countries and also in endemic parts of Iran. Leishmania major is the causative agent, Phlebotomus papatasi as the main vector and Rhombomys opimus is the most important reservoir of the disease. Species identification of Leishmania in a large scale of human samples is necessary to conduct a useful program for controlling the disease outspread. This study was done to identify the Leishmania using microscopic and molecular methods in suspected patients of Cutaneous Leishmaniasis by targeting ITS-rDNA gene, Golestan province, Iran. Materials and Methods: 121 smears collected from suspected patients of ZCL, in Eastern region of Golestan province, Iran during 2009-10, stained and examined under a light microscope. DNA of parasites extracted directly from smears and ITS-rDNA gene amplified. Positive samples digested with BsuRI restriction enzyme, according to RFLP method and subsequently the parasite was identified. After sequencing the ITS-rDNA gene, Molecular software was applied for verification of RFLP results. The achieved results were definitely approved by this procedure. Results: 113 out of 121 and 92 out of 121 samples detected as Leishmania positive using microscopic examination and molecular method respectively. All 92 molecular positive samples digested with BsuRI endonuclease and 90 individuals identified as Leishmania major. In order to final verification, 8 samples of Leishmania major sequenced and confirmed by molecular software analysis. Unfortunately, sequences of two samples which were not Leishmania major were not readable, and consequently, these could not be identified. Conclusion: Comparison of obtained sequences of current study with Gene Bank sequences confirmed L.major in human from Northern Iran. Other species of Leishmania were not identified in this investigation but detection of two other samples, which were not L.major, could indicate the role of other Leishmania species causing infection in human in Eastern region of Golestan province, northern Iran. These findings should be considered to improve the disease control programs, which can be led to increase the rate of public health in Golestan province.

Background and Objective: Bariatric surgery is the most effective treatment for morbid obesity. The classic procedure, jejunoileal bypass, has many complications. This study was carried out to assess the evaluation of clinical complications in morbid obese patients after modified jejunoileal bypass surgery. Method: This descriptive – analytic study was carried out on 120 morbid obese patients referred for bariatric surgery. A modified jejunoileal bypass was performed in which the defunctionalized organ eliminated by anastomosing its ends to the gall bladder and cecum. Weight loss and clinical complications were recorded after one year follow up. Results: The mean weight and body mass index reduced from 136 kg and 48 kg/m2 before surgery to 83 kg and 29/8 kg/m2 after one year follow up, respectively (P<0.05). Before surgery, articular pain (24.3%), dispana (21.6%), cardiovascular disorders (10.8%), fatty liver (5.4%) and sleep disorder (5.4%) due to obesity were recorded. One year follow up after surgery, articular pain (1.5%) and dispana (1.5%) were seen in patiants. No serious post-operative clinical complication was observed. Conclusion: One year follow up after surgery showed that the modified jejunoileal bypass is very effective in reducing body weight and does not lead to serious complication.
