Fascioliasis is a tropical zoonotic disease caused by the Fasciola parasite. The adult parasite usually resides in the liver and biliary ducts; however, several cases of ectopic fascioliasis (EF) have been reported. This study is a highlight on EF according to the confirmed case reports. In a setting of systematic review, we found 25 eligible articles containing 26 confirmed cases of EF (any date until 30 November 2018), including abdominal and intestinal EF in six cases, skin and subcutaneous tissues in five cases, eye in four cases, brain and pancreas in three cases, neck and lymph node in two cases, and lung, dorsal spine, and peritoneal cavity in one case, respectively. The result indicates that fascioliasis can have diverse ectopic forms and should be more attended in the endemic regions of fascioliasis in order to distinguish from other endemic diseases.
The parasites of genus Leishmania are the causative agents of one of the most widespread and devastating diseases. According to follow-up data, these medications may provoke adverse drug reactions, drug resistance, relapse, as well as financial burden. The mechanism of action of opioid drugs is primarily exerted via transmembrane G-protein coupled receptors. One of the potent synthetic immunomodulator agents is imiquimod with low molecular weight and unknown mechanism of action. Monocyte and macrophage are the primary site of action for imiquimod. Nalmefene is a well-known opioid antagonist agent which simultaneously inhibits these receptors and augments intracellular pathogenicity, hence providing opportunities to investigate their function. The aim of present work was evaluating the effect of morphine, imiquimod and nalmephen on the Leishmania major and investigating cytotoxic effect this drug on the uninfected macrophage and infected macrophage for detected early apoptosis, necrosis and secondry apoptosis by flowcytometry method. In this study we used morphine, imiquimod, nalmefene, and Glucantime. We treated promastigotes, macrophages, and infected macrophages with above drugs, and the apoptosis evaluated by flow cytometry. The results showed that in all concentration of morphine more than 98% of promastigotes remained alive that it is deduced that morphine lacks any lethal effect on L. major after 24 h, whereas in groups treated with Glucantime alone or in combination with Nalmephene and Imiquimod, 84.13%, 88.96% and 86.72% of promastigotes were alive, respectively. The results of macrophage treatment with morphine, imiquimod, and nalmefene demonstrated that most necrosis has occurred in nalmefene group (6.54%).

Background: Leishmaniasis is one of the most common parasitic diseases in tropical and subtropical regions of the world and is considered a threat to public health. Iran is also one of the most endemic areas of cutaneous leishmaniasis in the world. The causative species of cutaneous leishmaniasis is a protozoan from the Kinetoplastida order, which in Iran is Leishmania major (rural type) and Leishmania tropica (urban type). More than 70% of leishmaniasis in Iran is Leishmania major. The reservoir of the disease is humans in the urban type and field rodents in the rural type, and the vector is the female mosquito of the genus Phlebotomus. Methods: This study is organized as a review, in which, by searching the keywords cutaneous leishmaniasis, Leishmania major, plants effective against leishmaniasis in Iran, scientific-research articles, Google Scholar search engine information, Pubmed and Science Direct databases, the available books in this field were analyzed. Results: 5-valent antimoan compounds are used for the treatment of cutaneous leishmaniasis. Of course, not all patients need treatment because, in a large number of people, the lesion heals by itself, and due to the side effects of antimoan compounds, it is better to use fewer of these drugs. Therefore, the desire of patients and therapists to use herbal compounds has increased. Conclusion: Although cutaneous leishmaniasis is not usually associated with high Although cutaneous leishmaniasis is not usually associated with high mortality, the rate of infection is very high and causes malformed skin lesions that remain for more than a year in some cases, and even with standard treatment, scars remain. It remains forever and causes emotional pain for the patient. Therefore, domestic researchers have provided research on herbal treatments against Leishmaniasis, considering the history of traditional treatments in Iran and the scattered vegetation in the country.
Background and purpose: Previous Research shows the use of plasmids containing genes TSA to be useful as vaccines for Leishmania major. Recently, the role of interleukin-22 (IL-22) in tissue repair has been demonstrated. In this research, the effect of IL-22 on encoding TSA gene of Leishmania major in BALB/c mice was assessed.
