Euphorbia helioscopia L. is one of the important medicinal plants used in traditional medicine all over the world. This study was conducted to investigate the effect of ecological and edaphic factors on the active ingredients of this plant. For this purpose, the Euphorbia plant was collected from 3 different altitudes (1861, 949 and 236 m) with 3 replications. The extract was then prepared using acidic methanol and its phenol content was calculated according to the standard curve of gallic acid and flavonoid based on the quercetin curve. Its antioxidant activity was also investigated in 3 methods of DPPH, nitric oxide and reducing power. This study has clearly shown that the biological activity of the extract depends on the amount of phenol and its flavonoids. The results of this study show that Euphorbia plant in Challufe region has the best antioxidant activity in the nitric oxide test and at the highest concentration (800 μg/ml) compared to the other two regions. Our results also showed that the ability of the extracts of Euphorbia in the three studied areas to inhibit nitric oxide free radicals was concentration dependent and increased with increasing concentration of their anti-radical activity. The results of this study showed that the species of Euphorbia had a high total phenol and flavonoid content and antioxidant activity. Which can be used as a medicinal plant species.

The study was aimed to evaluate simultaneously the qualitative indices derived from the measurement of physicochemical parameters of water, as well as biological and demographic indices of the Bazangan wetland. Regarding to the high organic contamination from sediment amount and the stressful conditions of environment in this area, the highest relative frequency of macrobenthos was belonged to Chironomidae and Ephydridae families (resistant families to pollution) and the sensitive families to contamination (EPTs) were absent. The results of studying grading analysis and the total organic matter content in the sediments of samples stations during warm and cold seasons showed the texture of loam-silty, clay-sandy-loam and loam-clay. The maximum amount of organic matter (18.54%) in winter and the lowest amount of organic matter (4.65%) in spring was recorded in the stations. Finally, regarding the high correlation between biological and demographic indices and qualitative index with other indices, the parameters are more suitable indices to evaluate the ecosystem health of Bazangan wetland.

This study was conducted to identify 16S rDNA in the superior phenol-degrading bacteria for phenol bioremediation purposes. Two strains were selected as superior ones with higher phenolase activity and investigated in culture media with different pHs, temperatures, and carbon and nitrogen sources. The first strain removed 100% phenol in the medium contained 0.3 g/L phenol as carbon source, 0.2 % peptone and ammonium chloride as nitrogen source after 24 h, at 35 ºC in pH 7. While the second strain removed 100% phenol in the medium contained 1 % sucrose, 0.3 g/L phenol as carbon source, 0.2 % yeast extract and ammonium chloride as nitrogen source after 24 h, at 30 ºC in pH 7. The results of sequencing and alignment of 16S rDNA sequence revealed that the first strain belongs to Aneurinibacillus migulanus and the second one to Paenarthrobacter nitroguajacolicus. Overall, the two selected strains from the research could be considered as an appropriate candidate in phenol bioremediation purposes.

In stress condition, the blood corticoides increases which can affect general health of body as well as the function of some vital organs such as liver and kidneys. Consumption of herbal antioxidants may improve metabolic defects caused by stress. The aim of this study was to evaluate the effect of Foeniculum vulgare and Trachyspermum ammi essenses on blood metabolites and histopathological damages which is created by dexamethasone due to stress induction. Total of 40 mature Wistar male rats were randomly assigned to 5 treatments: 1- No stress, without supplementation, 2- Stress, whitout supplementation, 3- Stress, with receiving Foeniculum vulgare essense, 4- Stress, with receiving Trachyspermum ammi essense, 5- Stress, with receiving both of Foeniculum vulgare and Trachyspermum ammi essense. Dexamethasone injection was done for stress induction and essential oils of Foeniculum vulgare and Trachyspermum ammi and the mixture of them were gavaged. At the end, the blood samples were collected and then the samples of liver and kidneys were prepared. Stress induction, increased ALT and AST activities, but, feeding each essential oil and the mixture decreased activities of these enzymes. By treatment of Foeniculum vulgare, liver tissue vacuoles decreased significantly as well as edema and fat accumulation. In the stress group, hydropic degeneration and water accumulation were observed in cytoplasm of the tubular cells, but in Foeniculum vulgare treatment group kidney glomerului had normal appearance and cells edema significantly decreased. Treatment of herbal essential oils (especially foeniculum vulgare) had positive effect on liver and kidney health recovery and prevented from tissue damages due to stress induction in rat.

Macrobenthos can serve as a bioindicator for natural or anthropogenic environmental changes. Ghareh-Aghaj River is one of the most important rivers in Fars province that supply potable, agricultural and industrial water. This study aimed to investigate the changes of macrobenthos in different months and stations for one year from September 2018 to August 2019 to determine the water quality of Ghareh-Aghaj River in Fars province. For this purpose, 10 stations were selected from 190 kilometers of river length and sediment samples collected once every 45 days. Identifications were done using binocular stereomicroscope and benthic identification keys. BMWP, ASPT and Shannon Wiener indices were used to evaluate water quality. From the midstream zone to the Persian Gulf (stations 7 to 10) has severe pollution. These stations are surrounded by extensive farmlands that use pesticides and herbicides in a large scale, resulting agricultural runoff containing a variety of contaminants flowsinto the river. In addition, in the downstream stations, especially in Kavar (Station 7), the effluent of sand mines flows into the river, which has caused a severe change in the ecosystem of the lake. According to the results, the water quality of Ghareh-Aghaj River is relatively badand placed in the category of moderate to severe polluted

Mullets are among commercial species with good marketing condition which inhabit southern and northern coastal waters of Iran. Understanding of the diversity of mullets is a vital for their conservation. In this study, morphological characters of scale in ten mullet species from Iran are investigated. Specimens were collected from southern and two northern provinces of Iran during two years. Identification verified by reliable available identification keys. Minimum 5 scales were collected from left side of each specimen then photographed by stereomicroscope after rinsing. Results revealed that scales in different ten mullet species are distinguishable base on morphometric and meristic characters including General shape, number of Radii on scale, position of focus, Ctenii and Interradial tongue-like projection shape, scale area, scale length, scale width and distance between focus and up or low margin of scale. Among diagnostic characters, Two species of the Caspian Sea; Chelon aurata and Chelon saliens revealed significant smaller scale area and length (p≤0.05) while significant bigger scale length (p≤0.05) appeared in Ellochelon vaigiensis, Planiliza macrolepis and Planiliza subviridis .

Diazinon is one of the most widely used organophosphorus insecticides, to control plant pests in agricultural fields and is known to be a harmful environmental pollutant in the world. Therefore, the study aimed to investigate the hepatoprotective effects of alcoholic extract of Althaea officinalis against Diazinon-induced liver damage in adult male hamsters. 42 male hamsters were divided into six groups: The positive control group received distilled water, The negative control group received Diazinon poison, The group receiving the Althaea officinalis extract (300 mg/kg) and the group receiving the Althaea officinalis extract (600 mg/kg) received alcoholic extract of Althaea officinalis at doses of 300 mg/kg and 600 mg/kg of body weight, The group receiving Diazinon and the Althaea officinalis extract (300 mg/kg) and the group receiving Diazinon and the Althaea officinalis extract (600 mg/kg) received Diazinon toxin first and then alcoholic extract of Althaea officinalis at doses of 300 mg/kg and 600 mg/kg of body weight. Daily the hamsters were treated orally for 15 days. At the end of the experiment, blood samples were taken and serum levels of Alanine aminotransferase, Aspartate aminotransferase, Alkaline phosphatase, the whole (total) Bilirubin, the whole (total) protein and serum Albumin were measured. Data were analyzed by one-way ANOVA and Tukey's test using SPSS software. In Diazinon group, there was a significant increase in serum levels of Alanine aminotransferase, Aspartate aminotransferase, Alkaline phosphatase, the whole (total) Bilirubin and a significant decrease in serum (total) protein and Albumin levels compared with the positive control group. Alcoholic extract of Althaea officinalis caused a significant and dose-dependent decrease in the levels of hepatic enzymes and the whole (total) Bilirubin and significant increase in the whole (total) protein and serum Albumin levels. The result of this study showed that Althaea officinalis has a protective and therapeutic effect against Diazinon-induced hepatotoxicity in hamster.
