Objective: To investigate the fauna and seasonal activity of different species of sand flies (Diptera:Psychodidae: Phlebotominae) in Asalouyeh, the heartland of an Iranian petrochemical industry, Southern Iran, as a oil rich district. Sand flies are the vectors of at least three different kinds of disease, the most important of which is leishmaniasis, and it is a major public health problem in Iran with increased annual occurrence of clinical episodes.Methods:cleared in puris medium and identified morphologically, twice a month from April to March 2008.Results:A total of 3 497 sand flies of rural regions were collected by sticky traps fixed, and Sinton, 1928, Phlebotomus papatasi Scopoli, 1910, Phlebotomus bergeroti Parrot and Phlebotomus sergenti Parrot) and one of genus Sergentomyia (Sergentomyia tiberiadis Alder, Theodor & Lourie, 1930). The most prevalent species was Phlebotomus papatasi, presented 56.4% of the identified flies. The others were Phlebotomus sergenti (22.5%), Phlebotomus alexandri (4.5%), Phlebotomusbergeroti Predominant species included four of genus Phlebotomus (Phlebotomus alexandri than that of males (32%). The abundance of sand flies represented two peaks of activity; one in early May and the other one in the first half of September in the region. (12%) and Sergentomyia tiberiadis (5%) as well. The percentage of females (68%) was more Conclusion: Phlebotomus papatasi is the probable vector of zoonotic cutaneous leishmaniasis in the region. Further molecular studies are needed to determine the definite vector of the region.

Objective: To investigate the prevalence of fecundity and other reproductive problems among a group of farmers in Kavar district of Fars province, southern Iran.
Methods: A total of 268 randomly selected married male farm workers were investigated. A questionnaire was devised and validated [Cronbach’s α-coefficient (0.81)]. Subjects were directly interviewed and the questionnaire forms were completed for them.
Results:The prevalence of current primary infertility among the studied population was about 7.4% (P=0.001). Similarly, 6.3% of farm workers had offsprings with congenital malformations. Finally, 1.5% and 9% of farmers’ wives had a history of stillbirth and abortion, respectively. It was concluded that the prevalence of current primary infertility were higher among farm workers families than in the normal population (P<0.05). Additionally, stillbirth and spontaneous abortion were more common in the wives of farm workers than in the normal population, although the difference did not reach statistical significance.
Conclusions:These effects are likely to be attributed to the exposure of farm workers to pesticides.

Non-invasive therapeutic methods have recently been used in medical sciences. Enzymes have shown high activity at very low concentrations in laboratories and pharmaceutical, enabling them to play crucial roles in different biological phenomena related to living organism, especially human medicine. Recently, using the therapeutic methods based on non-invasive approaches has been emphasized in medical society. Researchers have focused on producing medicines and tools reducing invasive procedures in medical. Collagenases are proteins which catalyze chemical processes and break the peptide bonds in collagen. Collagen may be generated more than the required amount or produced in unsuitable sites or may not degrade after a certain time. In such cases, using an injectable collagenase or its ointment can be helpful in collagen degradation. In both in vitro and in vivo tests, it has been revealed that collagenases have several therapeutic properties in wound healing, burns, nipple pain and some diseases including intervertebral disc herniation, keloid, cellulite, lipoma among others. This review describes the therapeutic application of collagenase in medical sciences and the process for its production using novel methods, paving the way for more effective and safe applications of collagenases.

METHODSA total of 3 497 sand flies of rural regions were collected by sticky traps fixed, and cleared in puris medium and identified morphologically, twice a month from April to March 2008.

RESULTSPredominant species included four of genus Phlebotomus (Phlebotomus alexandri Sinton, 1928, Phlebotomus papatasi Scopoli, 1910, Phlebotomus bergeroti Parrot and Phlebotomus sergenti Parrot) and one of genus Sergentomyia (Sergentomyia tiberiadis Alder, Theodor & Lourie, 1930). The most prevalent species was Phlebotomus papatasi, presented 56.4% of the identified flies. The others were Phlebotomus sergenti (22.5%), Phlebotomus alexandri (4.5%), Phlebotomus bergeroti (12%) and Sergentomyia tiberiadis (5%) as well. The percentage of females (68%) was more than that of males (32%). The abundance of sand flies represented two peaks of activity; one in early May and the other one in the first half of September in the region.

CONCLUSIONPhlebotomus papatasi is the probable vector of zoonotic cutaneous leishmaniasis in the region. Further molecular studies are needed to determine the definite vector of the region.

Objective: To investigate phytochemicals present in the essential oil from aerial parts of eastern red cedar, Juniperus virginiana (J. virginiana) L. (Cupressaceae) and to determine its killing and repellent activities against larvae, pupae, and adults of the Asian malaria mosquito, Anopheles stephensi (Diptera: Culicidae). Methods: J. virginiana essential oil was extracted by hydrodistillation, and its chemical composition was determined by gas chromatography-mass spectrometry. Seven different logarithmic concentrations of J. virginiana essential oils were used in larvicidal and pupicidal assays. J. virginiana essential oils-impregnated bed nets were applied in a designed animal module to test excito-repellent activity against adult mosquitoes. Results: Fourteen constituents corresponding to 99.98% of J. virginiana essential oils were identified. Five main components were terpinen-4-ol (25.21%), camphor (19.89%), E-3-hexen-1-ol (13.30%), γ-terpinene (7.86%), and l-menthone (2.27%). The LC

Objective: To study agents of animal wound myiasis in various geographical districts of Fars province. Methods: This study has been done in Fars province, located in the southern part of Iran. Sums of 10 358 domestic animals have been visited from April 2011 to March 2012. The infected wounds in any parts of animal body were sampled by means of forceps. Results: About 61% of all animal wound myiasis were caused by larvae of Wohlfahrtia magnifica. The most wound myiasis cases due to this species occurred in central part of Fars province. There wasn't any significant difference between sheep and goat in infestation with myiasis (P>0.05). The infestation rate of myiasis in cattle community was 0.86%. Conclusions: The infestation rate of livestock was lower than other works in Iran and some other countries like Saudi Arabia. Chrysomya bezziana has been mentioned as main myiasis agent in Iran. But in this study it cleared that similarly to some European countries, the common animal myiasis agent in Iran is Wohlfahrtia magnifica. Introducing new species as principal agent for myiasis can help public health and animal husbandry policy makers to prepare sufficient and effective control and/or preventive measures for this disease.
