Abstract:
Different species of Syrphid flies are beneficial insects in nature and are important in agriculture. During a faunistic study on syrphid flies (Dip.:Syrphidae) on 2011 to 2012 of Jolfa region (East Azarbaijan province), one Merodon Meigen, 1803 species was collected. They were identified as Merodon latifemoris Radenkovic, based on morphological characters as a new species from Iran region.
In this study, species was collected, and transferred to the Laboratory of Entomology, in Islamic Azad University of Marand and was studied at the morphological character.
The syrphidae important organs such as legs, wings, thorax, abdomen and genitalia were examined. In this research isolated end of the tergit, and transferred in to KOH 10% for 24-12h and then transferred in to alchole 10%, so added one drope glycrin at study time, and was recognized by prestigious keys. Their figures and a simple diagnostic key were provided for their determination in this region.

Diabetes disrupts processes related to learning, memory, and cognition. Considering the potential anti-diabetic effect of the medicinal plant turmeric (curcumin) and its enhancing effect on memory and learning, in this research, the effect of inter peritoneal administration of the curcumin on learning and memory in diabetic rats was investigated. In this study, the male rats were divided into five groups: control, control treated with curcumin 50 mg / kg, diabetic and diabetic treated with curcumin 10 and 50 mg/kg. Curcumin was administered for five weeks after seven days of streptozotocin 60mg/kg interparietal injection and the passive avoidance task was assessed through the operation. Streptozotocin injection significantly increased blood glucose and markedly decreased both STL1 (the short memory) and STL2 (the long memory) in the avoidance learning test. Chronic administration of curcumin as an active ingredient in turmeric significantly increased short-term and long-term memory in the diabetic groups. Therefore, chronic use of cinacurcumin reduced memory and learning impairment and enhanced the capability of memory and recall in diabetic rats.

Alzheimer's disease is a common form of progressive dementia and usually occurs between the sixth and ninth decades of life, given that there is a direct relationship between steroid hormones and neurodegenerative diseases, so the present study was designed to explore effect of testosterone in memory impairment induced by intra-cerebroventricular (icv) injection of streptozptocin (STZ) as a model of sporadic Alzheimer disease (AD). Study was carried out on male Wistar rats. Adult male Wistar rats were intracerebroventricularly (icv) infused with STZ (3mg/kg/icv) on d 1 and d 3, and a passive avoidance task was assessed 2 weeks after the first injection of STZ. Castration surgery was performed in another group of rats, and the passive avoidance task was assessed 4 weeks after the operation. Testosterone (1 mg/kg.d, SC), the androgen receptor antagonist flutamide (10 mg/kg.d, ip), the estrogen receptor antagonist tamoxifen (1 mg/kg.d, ip) or the aromatase inhibitor letrozole (4 mg/kg.d, ip) were administered for 6 d after the first injection of STZ. STZ administration and castration markedly decreased both STL1 (the short memory) and STL2 (the long memory) in passive avoidance tests. Testosterone replacement almost restored the STL1 and STL2 in castrated rats, and significantly prolonged the STL1 and STL2 in STZ-treated rats. Administration of flutamide, letrozole or tamoxifen significantly impaired the memory in intact rats, and significantly attenuated the testosterone replacement in improving STZ- and castration-induced memory impairment. Testosterone administration ameliorates STZ- and castration-induced memory impairment in male Wistar rats.

The rodents order is the largest class of mammalians; and they are very important in the medicine and agriculture. During of faunistic study on rodent order (Order: Rodent) in Marand region (East Azerbaijan province), North west of Iran, from 2012 to 2015, 6 Species collected and diagnostic. In this research, species were collected from the mountains, farms, villages and houses by traps and poisonous baits. The rodents recognized in Marand region are: 1- Mus musculus, 2- Ellobius fuscocapillus, 3- Microtus socialis, 4- Apodemus sylvaticus, 5- Meriones persicus,6- Cricetulus migratorius. Their figure and a simple diagnostic key are provided to determin of them in this region.

The aim of this research was to study the Agamidae family species in East Azerbaijan, Iran. From among the many different habitat regions, several areas were randomly selected for trapping. To meet the goal, 100 samples of the Agamidae family lizards including five species (Trapelus agilis, Trapelus persicus, Phrynocephalus scutellatus Phrynocephalus persicus, Laudakia nupta) out of three different genera were collected. After take the specimens, Specification subject to change Such as:, sampling location, date, eyes color and etc, was recorded. Samples, based on the size and type and conventional methods were killed, and were transported to the laboratory for identification. After transporting these specimens to the laboratory, they were fixed in 10% formalin and, then they were identified by the valid identification keys.
