Shortly after gulf war (G.W) thousands of war veterans referred with sign and symptoms of an unknown disease called G.W illness. Despite multiple studies undertaken by several non-governmental and governmental centers this illness remains unclassified and can not be coded by international classification of disease (I.C.D). The etiology has not been found and the illness appears to be multifactorial and basically related to use of depleted uranium (D.U) weapons, chemical warfare (C.W) and biological agents. This article reviews this illness and the adverse effects of D.U and B.c.W agents in the G.W battlefields.

There are several global marine forecast systems based on large scale regional data covering Iranian seas which are freely available on their websites. They are also several local marine forecast systems in Iranian waters. This paper performs an inter-comparison among different marine forecasting systems in Iranian seas in order to evaluate the accuracy and difference between them and give a proper ground for further investigation and research in this crucial issue. For this purpose, the results of two forecasting system in several points in the Persian are compared and the reason of differences are investigated.

Background and Aim: The widespread use of antibiotics has been led to increased emergence of antibiotic resistant bacteria and high mortality and morbidity rates due to infectious diseases. Pseudomonas aeruginosa is one of the most important causes of nosocomial infections, which shows high resistance to a wide range of antibiotics. So, finding new and effective antimicrobial compounds in order to overcome antibiotic resistant infectious diseases is so critical. Screening of native actinobacteria can be an effective strategy to find novel antimicrobial compounds. The aim of current study was isolation, screening and identification of rare actinobacteria to find the strains which produce antimicrobial compounds against P. aeruginosa. Material and Methods: Thirty samples of water and sediments were collected from Persian Gulf and Oman Sea and used for isolation of actinobacterial strains. After isolation of actinobacteria, their metabolites were extracted and their anti-P. aeruginosa activities were investigated. Minimum inhibitory concentration (MIC) of the most efficient extract was determined using broth microdilution method. Finally, the most efficient strain was identified. Ethical Considerations: In this study, all principles of biosafety and bioethics have been considered. Findngs: Fifty actinobacteria were isolated from water and sediments. Five isolates had considerable antimicrobial activity. MIC value of the most efficient extract against P. aeruginosa was 100 μ g/ml. Molecular analysis of 16SrRNA showed that the most effective fermentation broth extract belongs to Micromonospora and has 99. 8% similarity to M. chalcea. Conclusion: The current study revealed that the water of southern Iran and their sediments are promising sources of potent rare Actinobacteria in the production of antimicrobial compounds against P. aeruginosa.

A large area in the north of Persian Gulfand sea of Oman have been used for nesting by a great number of sea turtles.The researches done by Food and Agriculture Organization (F.A.0) indicate that five species of sea turtles in the region are found as follow:1- Green turtle (Chelonia mydas)2- Loggerhead turtle (Caretta caretta)3- Hawksbill turtle (Eretmochelys imbricata)4- Oliveridely turtle (Lepidochelys olivacea)5- Leatherback turtle (Dermochelys coriacea)On the assumption that the distribution of the species on the sides of Persian Gulf and sea of Oman is not different, in the current research by concidering the same subject, their distribution is investigated on the basis of field activities and the existance evidence .The obtained results show that more than 50 habitates in southern coast of Iran is used for grazing, mating and nesting .It reveals that Green and Hawksbill turtle were observed more in these regions.

A three dimensional numerical model namely ROMS (Regional Ocean Modeling System) and observational data are used to study the thermohaline front of Persian Gulf Outflow in the Oman Sea. The simulation results show the formation of a thermohaline front at 80m depth in the direction of the north-east-southwest at the mouth of the Oman Sea. The seasonal thermohaline front variability was also identified, during winter a heat and salty tongue stretches from the Strait of Hormuz to the continental shelf along the south Oman coast. During summer, it shows a current departing from the coast moving forward to the middle of the Oman Sea. Thermohaline front is observed throughout the year, in summer as unified and patchy in winter. Intrusion of warm and salty water of Persian Gulf into the Gulf of Oman displays a local increase in salinity in the middle layers in 150-450m and 100-400m depths in winter and summer respectively which expresses two boundaries in the upper and lower layers. Diffusive convection and salt fingering can be seen in both the upper and lower boundaries respectively. The complex ocean flow patterns are result of monsoons in the Oman sea area. During the winter monsoon, a single cyclonic gyre is often observed near 58◦ E and during the Southwest monsoon in summer, a dipolar eddy near Ras al Hamra and an anticyclone’ s gyre in 25° N are detected.

Regarding these brief backgrounds on copyright issues in the Persian Gulf and Oman Sea Waters, 18 species have been identified. Economically important species of fish and fishing, green tiger shrimp (penaeus semisul catus) in the Persian Gulf and Oman Sea which are found in most habitats, but most of its distribution and fisheries ae in the waters of Bushehr. Banana shrimp (Penaeus indicus) is the second and most commercially caught in the waters of the province. Others such as Indian white shrimp (Penaeus indicus) and black tiger shrimp (Penaeus monodon), despite having a large body, due to the low abundance and habitat limitations, cannot be economically exploited. Preliminary investigation of proliferation and shrimp in the calendar year 1363 (1984 AD) by the Fisheries Research Institute of Iran's Bushehr was shrimp investigation center belonging to the country. Achievements of this research work introduced three important commercial species of green tiger shrimp, white Hindi and Vanamy the aquaculture industry in the country. Production of shrimp in the country from, 54 tons in 1373 (1994AD) to 250.5 tons in 1386 (2007AD), was over. Maximum production of shrimp in the country was in 1383 (2004) to 8930 tones of the province, with 5,600 tons ( 63%). Given the diversity of shrimp with a regional vision, reproduction and breeding species can be produced by a variety of conditions with power production of maximum -resistant, disease resistant.

The pharaoh cuttlefish (Sepia pharaonis) is the most aboundant species in the Persian Gulf and Oman Sea. The stock patterns of this species were studied concerning biological and morphological aspects. In addition to measuring the biological patterns, 20 quantitative factors were measured. The results of LSD test showed that tentacle organ is indicative factor which showes significant difference between male and female specimen of Bushehr and Balouchestan regions. Regarding to length and weight frequencies data the results indicated that males are always bigger than females and also, the cuttlefishes of the Gulf of Oman are bigger than Persian Gulf samples. The results of cluster analysis for both sexes showed that the cuttlefishes of both studied region belong to separate stocks. Taking into consideration the findings of present study including: (1) difference in spawning season, (2) results of dendrograms, (3) observed significant differences in one-way analysis of variance (ANOV A) for morphometric measurements, (4) differences in body length and weight, (5) as well as ecological variations of the Persian Gulf and Oman Sea, have indicated that: "the pharaoh cuttlefishes of Bushehr and Balouchestan belong to two separate stocks.
