Ionizing radiation cause damage and even cell death to body tissues. Protective compounds are administered before radiotherapy to reduce the harmful effects of irradiation. The aim of this study was to investigate the effects of gamma radiation on spermatogenesis in adult rats and the protective role of Para amino propiophenone.
PAPP was injected intraperitoneally at different doses 40, 20, 10 mg / kg half an hour before exposure to gamma rays (2 Gy). The animals after 3 days were killed. After removing the testes of animals and preparation of slides, the number of spermatogonia, primary spermatocytes, spermatids, spermatozoa, Leydig and Sertoli were counted.
The results showed significantly reduction of the number of spermatogonia, spermatids, spermatozoa, Sertoli, Leydig, in the group that treated with 2 Gy of gamma rays, compared with the control group (P ≤ 0.05). While the number of primary spermatocytes in the gamma treatment groups compared with the control group increased significantly (P ≤ 0.05).
PAPP role as a protector was well represented. It seems that PAPP protects cells and tissues from damaging effects of free radicals under the influence of gamma radiation with low oxygen delivery and hypoxia generation.

For comparing the morphology and morphometric otolith parameters in Liza aurata of Caspian Sea and Liza klunzingeri of Persian Gulf, 35 otolithes (Sagittae) of every species are extracted from under gills region. After washing, their morphometric parameters measured. These parameters include otolith length, width, thickness, ant rostrum, and rostrum, post rostrum in right and left sagittae. In addition to the otolith outline, mode position and mode opening of the sulcus acusticus were examined. Obtained results shown that otolith shape was different in two species. In both of them otolith was medium in size and long. Their thickness was thin. There was a strong correlation between right and left otolith length and right and left otolith thickness in Liza aurata (p≤0.05).but There was not a correlation between right and left otolith width, between otolith length and width and otolith length and thickness(p≥0.05) There was a strong correlation between right and left otolith length and right and left otolith width in Liza klunzingeri (p≤0.05).but There was not a correlation between right and left otolith thickness, between otolith length and width and otolith length and thickness(p≥0.05). Difference in regression relationship between morphometric characteristics of otolith in two species indicates the latitude and temperature effect on the morphometric characteristics of the two species of mullet fish.

Replacing dietary fish oil with vegetable oils has various effects on immune responses. This study was conducted to evaluate the effect of replacement of fish oil (FO) by canola oil (CO) on immune system of the rainbow trout Oncorhynchus mykiss (63.5±0.6 g mean individual weight) for 50 days. Four experimental diets were formulated with partial or complete (33%, 67%, 100%) replacement of FO with CO. The diets were fed to duplicate groups of 25 trout fingerlings. Fish were randomly assigned to each of eight 500 liter fiberglass tanks (500L). The results showed that serum AST, ALP, ALT and LDH levels were higher in fish fed the 100% FO diet than the other fish. Serum lysozyme activity and immunoglobulin (IgM) was higher in fish fed the 100% FO diet than the other fish. Also, C3 and C4 complements were significantly higher in fish fed the 100% FO diet than that the other fish. However, alternative complement activity (ACH50) was higher in fish fed the 100% CO diet. Since the amounts of serum liver enzymes in CO treatment groups was lower than their amounts in FO treatment group, so we can conclude that replacing dietary FO with CO does not have any negative effects but it causes improvement of immune factors and enzymes of rainbow trout (Oncorhynchus mykiss) in period of 50 days.

Trichophyton rubrum is the most common cause agents of dermatophytosis in human skin and nail tissue. Some properties of T. rubrum have been investigated in molecular level; however no information is available regarding the Ran protein in this dermatophyte. The effects of lovastatin were investigated by using various concentrations of this medicine in T. rubrum cultures. Nucleic acids (RNA) were isolated from obtained mycelial mass of this fungus by standard methods. Pairs of primers were designed and synthesis from highly conserved regions of the Ran protein genes in other eukaryotic cells. Then primer and cDNA which synthesis of RNA extracted of T. rubrum utilized in PCR. The growth of fungi was decreases in this medium. Lovastatin depend on concentration reduced growth of fungi and gene expression of Ran protein gene, and with increase of drug concentration growth and gene expression were decreased.

The goal of this study was investigation of the effect of different semen extender including milk (M), Tris-egg yolk (TEY), and Tris-soybean lecithin (TSL) on ram sperm quality during cool storage condition. Semen was collected from four rams using artificial vagina. Afterward, ejaculates were pooled and then divided into three aliquots. Aliquots were diluted with either M, TEY or TSL based extenders and stored at 5°C for 48 hours. Total motility, progressive motility, and sperm viability were evaluated at 0, 3, 6, 24, and 48 hours after starting the experiment. The results showed as the experiment proceeds, the total and progressive motility significantly decreased in each three treatments. Also, total and progressive motility had no significant difference between three treatments, in exception of 3 hours after starting the experiment. Sperm viability as the experiment proceeds, significantly decreased in each three treatments, but there was no significant difference between different treatments. The results of this experiment show total motility, progressive motility, and sperm viability when semen was diluted with TSL extender had no significant difference in comparison with M and TEY extenders. So, TSL as an animal protein free extender can be an appropriate substitute for semen extenders containing milk and egg yolk to store ram semen in cool condition.

Pontogammarus maeoticus is an epibenthic amphipod that is very well adapted to life in estuaries and shallow coastal waters. In the southern coasts of the Caspian Sea, this species is the most abundant macrofaunal species. In the present study, the effect of two important environmental factors, temperature (25 and 30ºC) and salinity (4, 8 and 12ppt), on the life history of adult individuals of P. maeoticus was analyzed in laboratory to assess survival rate, growth and reproductive characters. The results of this study showed that survival rates of adult individuals were similar (P>0.05) among different treatments, despite higher survival rate at 30°C. The growth rate of adult individuals was significantly affected by temperature-salinity interaction (P<0.05). The growth rate was significantly lower in 25ºC -8 and 12ppt and 30ºC-12ppt compared with the other combinations of temperature-salinity. Adult individuals of P. maeoticus at 25°C required one week more time than those reared at 30°C to complete their sexual maturation period. The relative number of released offspring showed no considerable difference among the different temperature-salinity conditions (P>0.05). In overall, the combination of 30°C and 8ppt can be considered as the optimal temperature-salinity condition for culture of adult P. maeoticus.

A 60 day trial was conducted in order to determine optimum level of lipid for oriental river prawn. 5 treatments containing 0, 3, 6, 9 and 12% lipid added to diets with iso protein (40%) were formulated. Juvenile prawns with initial average weight of 0.967 g were randomly stocked between 15 glass aquariums. The juvenile prawns were fed at satiation in three times (8, 12 and 18 hrs). Growth performances in the term of average weight (WG), survival rate (SR), food conversion ratio (FCR), condition factor (CF), lipid productive value (LPV), specific growth rate (SGR) and protein efficiency ratio (PER) were evaluated. Generally, the best growth performances were at 9% lipid added diet (i.e. 11.27) and were significant with others (P < 0.05). With increasing lipid in diets, the moisture was decreasing while lipid was moderately increased. In spite of the diets being iso protein, the body protein was increased in treatments 9 and 12%.

Understanding environmental factors which affect burrow site selection by reptiles is known as a useful tool for biodiversity conservation and management. The aim of this study was to investigate the role of vegetation richness, diversity, and cover on burrow site selection by Mesopotamian spiny-tailed lizard in Mish Dagh Protected Area, Khuzestan province. Vegetation characteristics were measured in 415 presence/absence circle plots (11.5-m radius). The entrance hole of active dens was taken into account as the center of presence plots. Absence plots also were located in 200-500 m apart from each entrance hole in one of the eight randomly selected cardinal directions. We used t-test to evaluate the differences of vegetation richness, diversity and cover between presence/absence plots. Our results revealed that vegetation factors were significantly different between present and absence plots. Vegetation around den site play critical role to supply food and shelter for lizards which affects their survival rate positively.

Capoeta trutta living in the Middle East and Iran in the catchment Region of the Tigris and Forat and Karun shoot lives. Samples caught by electric fishing two stations using this species as season of the from Jun 2011 to August 2011 the kharchangrod and Cheshmemahi Gamasyab River the province. Within a year the total number of samples, 224 fish were caught and analyzed. Overall, average total length of the two stations 13.22 ± 5.06 cm and 34.44 ± 30.08 g total weight is 17.37 ± 2.84 and 12.48 ± 5.02 cm and average weight of kharchangrod in the stations, and Cheshmemahi, respectively, is 61.67± 28.81 and 29.56 ±27.56 g. Both two stations fish were caught with five groups +0 to +4 are the age group+1 is dominant. The logarithmic relationship between length and weight of kharchangrod and Cheshmemahi sampling stations, respectively, W= 2.85 TL- 4.09 and W=2.94 TL- 4.4 the growth pattern of fish in both stations is negative allometric. Kharchangrod growth equation parameters Brtalanfy station is L ∞= 204.151, k= 0.56 and t. = - 1.68 and Cheshmemahi station is L ∞= 211.489, k= 0.59, t. = - 0.74.

In this study, the resistance of rainbow trout was assayed after feeding with a commercial probiotic (Bactocel®) and Manan Oligosaccharide prebiotic in challenging with hypoxia and temperature stresses. 720 fish with average initial weight of 10±2 g under 6 feeding treatments (in 3 replicates) were tested: 1) feeding with commercial food (control), 2) feeding on 100 mg Bactocel/kg feed, 3) feeding on 2.5 g Manan oligosaccharide/kg feed, 4) feeding on 5 g Manan oligosaccharide/kg feed, 5) feeding on 100 mg Bactocel and 2.5 g Manan oligosaccharide/kg feed, 6) feeding on 100 mg Bactocel and 5 g Manan oligosaccharide/kg feed. The results showed that intestine of fish fed on both probiotic and prebiotic contained significantly higher number of probiotic bacteria. Minimum mortality under temperature stress was observed in treatments fed on both probiotic and prebiotic (P<0.05) and maximum tolerance to anoxia stress was detected in treatments 4 and 6, significantly higher compared to control group.

The use of liver histopathology in various fish species as a biomarker in marine monitoring programs to assess the biological effect of exposure to contaminants is well established although the Euryglossa orientalis has repeatedly been recommended as an appropriate bioindicator for monitoring purposes in the Persian Gulf, information on histopathological liver alterations of this species is scarce. In order to obtain an overview, a total of 80 flounder, collected in the period between winter 2011 and summer 2012 from 7 sampling sites distributed over north of the Persian gulf, were histologically analyzed. Liver lesions were recorded and classified according to established liver lesion categories. A high prevalence of non-specific and early toxicopathic non-neoplastic hepatic lesions was recorded. In contrast, pre-neoplastic lesions were observed only in some cases and neoplastic changes were absent. Indices of liver tissue damage in Euryglossa orientalis Eskeleh Nafty Majidieh, Bushehr and Bandar Abbas significantly higher than other stations (p<0.05). The results revealed that the observed alterations may indicate effects of environmental stressors including contaminants. The results of the present study, thus, support the application of Euryglossa orientalis liver histopathology in environmental monitoring.

The gender of the dominant Taxon Zoanthus is a subclass of Zoantharia which is known to have a wide variety of colors. This feature make the species identification based on morphological characterization difficult and somewhat impossible. To ensure the accuracy of the identification of genetic research is, hence, inevitable. For this reason, 10 colonies with various colors in three repetitions were collected from the islands of Lark, Qeshm, and Kish. After DNA extraction from the samples, 16S rRNA gene fragment were amplified and finally sequenced by using the PCR method. The results of the present study show that the nucleotide sequence of this mitochondrial gene fragment is identical in all the examined samples and is consistent with the reported sequences of the species of Zoanthus sansibaricus.
What this study obtained is undoubtedly a systematic report from the color variation of the available samples in the Iranian islands of the Persian Gulf. Observation of brown, green, gray, red, pink and purple polyps, green and brown tentacles, green, red, blue and pink oral color with oral disc green, red, blue, pink and gray colors confirms a wide range of colors in this species.

Sefidroud is one of the important water resources of Gilan province and recognition of parasitic condition of this river’s fishes, is very important in determination of juvenile’s destination that are released every year by North Fisheries. In a study of 25 samples of Spirlin in Sefidroud River that were caught in spring 1391, in 3 fishes Glochidia were found. The glochidia is a special microscopic larval stage of some freshwater mussels, aquatic bivalve mollusks in the family’s Unionidae and Margaritiferidae, the river mussels and European freshwater pearl mussels. These fishes were studied of biology, age and sexuality. Also the size and position of larvae were studied. Fishes were 2+ and 3+ and all of them were female. Maximum length of larvae was 1.6 mm and minimum length was 0.8 mm, also maximum height of these larvae was 0.9 mm and minimum height was 0.5 mm.
