Considering the importance and undeniable impact of air pollution on human health, the purpose of this research was to investigate the effect of respiratory pollutants on blood parameters and general health of Hormuz Petrochemical personnel in Assalouye. In this experimental research, 60 male employees with at least one year of work experience were randomly divided two experimental groups of 30 people (including the personnel of Hormoz Asalouye Petrochemical Company as the group exposed to respiratory pollutants) and the control (personnel of the Social Security Department of Kazeroon as the group not exposed to pollutants). In order to investigate the effects of respiratory pollutants on changes in blood parameters, blood samples were taken from both groups.Also, to determine the general health of the employees, the standard questionnaire of the Goldberg general health scale was used. Data analysis was done using independent t-test statistical method. The results showed that the amount of white blood cells, platelets and average platelet volume in the exposed group showed a significant difference compared to the non-exposed group (P≤0.05), but the amount of red blood cells and hemoglobin did not differ significantly between the two groups(P>0.05).It was also observed that air pollution has negative effects on mental health and in the group exposed to respiratory pollutants, it led to an increase in physical symptoms, depression and anxiety (P≤0.05). In line with the results of this research, it can be concluded that exposure to air pollutants significantly causes changes in hematological parameters and increase in general health symptoms.

Diazenone is one of the most important organospheric pesticides that is widely used in agriculture and homes to control insects in the soil, plants and other crops. Diazenone is used to control plant pests in many agricultural fields that are located near fresh water sources, It is common.Therefore, in this research, the effect of agricultural poison diazenon was investigated by calculating LC50 on blood parameters and lactobacilli in the intestine of Hypophthalmichthys nobilis. In this experiment, fish were exposed to different concentrations of diazenon poison for 15 days. The amount of blood parameters of red and white blood cells and the presence of lactobacillus species were investigated in 6 treatments with 3 repetitions over a period of 15 days. Then, blood sampling and sampling from the intestines of Hypophthalmichthys nobilis were done. The results showed that the hematological indices of Red carp exposed to different doses of diazenon poison showed a significant decrease in RBC and WBC with increasing poison concentration (p<0.05). Also, the results showed that in all different doses of diazenon poison, the lack of growth of Lactobacillus bacteria compared to the control group on MRS agar culture medium had significant differences (p<0.05). Finally, it can be mentioned that the use of intestinal and blood Lactobacillus samples to investigate the microbial and hematological indicators of Sargandeh carp can be used as biomarkers for measuring and tracking the effects of diazenon poison in aquatic communities.

Today, Spirulina micro-algae is cultivated in many countries as a rich source of protein, unsaturated fatty acids, vitamins, minerals and antioxidants. In this study, the effect of replacing spirulina microalgae powder with different amounts of industrial vitamin-mineral premix was compared as an additive to stimulate the growth performance of broiler chickens. 200 one-day-old broiler chickens were randomly selected among 3000 chickens and divided into five treatments at Mehrgan Jihad Agricultural Research Center in Kermanshah province The diet of the first group, which was considered as a control treatment, includes (100% industrial supplement and no spirulina), the first treatment T1(25% spirulina and 75% industrial supplement), the second treatment T2 (50% spirulina and 50% industrial supplement), The third treatment T3 (75% spirulina and 25% industrial supplement) and the fourth treatment T4 (100% spirulina) were used. After 42 days, there was no mortality in the treatments, in the T1, T2 and T4 treatments, live weight significantly (P<0.05) increased compared to the control group, and the amount of feed conversion ratio (FCR) in the T2 treatment decreased significantly. Therefore, T2 showed the best performance Then the biochemical parameters of blood serum in T2 were checked, which showed a significant (P<0.05) increase in glucose, total protein and albumin, HDL and LDL and a decrease in triglyceride and cholestrol levels. Based on findings, it is concluded that by replacing 50% of the industrial vitamin-mineral supplement with spirulina powder, the growth performance, feed conversion ratio and blood parameters in broilers can be improved.

The present study was performed to investigate the effect of furosemide on oxidative stress, mortality due to ascites and some blood parameters in broiler chickens. A total of 450 Ross 308 days-old chicks were assigned to 3 groups (control and two treatments of 30 and 60 ppm zamide) in a completely randomized design with 5 replications and 30 chicks per replicate. The birds were subjected to a special cold temperature program to induce ascites. Blood parameters: red blood cell count, hematocrit, hemoglobin, white blood cells, activity of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, creatine kinase and oxidative stress parameters such as; Plasma antioxidant capacity, plasma malondialdehyde, glutathione peroxidase and superoxide dismutase activity, glucose, protein, triglyceride, cholesterol and high-density lipoprotein were measured. Performance parameters of body weight gain, feed intake and feed conversion ratio were also evaluated. Deaths were recorded daily and described to differentiate the cause of death and determine ascites. The results showed that administration of 60 ppm of furosemide significantly reduced weight and feed intake as well as improved feed conversion ratio (P<0.05). In addition, furosemide, significantly decreased ascites index and ascites losses (P<0.05). Also, level of 60 ppm furosemide, increased white blood cells, plasma antioxidant capacity, glutathione-peroxidase activity). Decreased plasma protein, malondialdehyde and activity of plasma aspartate, aminotransferase, alkaline phosphatase, and creatinine kinase (P<0.05). The results of this research show that the level of 60 ppm Furosemide can reduce the problems caused by high blood pressure in birds with this metabolic syndrome by improving its antioxidant status.

Regarding the role of arginine in vasodilatation and reduction of blood pressure and the possibility of replacing this amino acid with guanidinoacetic acid, a test was conducted with 400 chicks in 5 treatments (control, two levels of 0.5 and 1% arginine, and two levels of 0.15 And 0.3% Guanidininostech) in four replications in a completely randomized design. Birds were subjected to a cold temperature program for induction of pulmonary hypertension syndrome. Blood parameters (RBC, hemoglobin, hematocrit and heterophile / lymphocyte), biochemical parameters (lactate, urea, uric acid and nitric oxide), enzymatic parameters (LDH, AST, ALT, CK) and antioxidant TAS, MDA, GPX, SOD) in plasma were measured at the end of the experiment (day 42). The results showed that supplementation of 1% arginine and 0.15% guanidinoacetic acid significantly decreased the heterophilic/ lymphocyte index, hematocrit, urea and uric acid, and increased nitric oxide (P <0.05). Treatment with 1% arginine and 0.15% guanidinoacetic acid reduced malondialdehyde and increased activity of superoxide dismutase and creatine kinase in plasma (P <0.05). The level of 1% of arginine also significantly increased the activity of glutathione peroxidase enzyme in the plasma. Other measured parameters were not significantly affected by experimental treatments (P> 0.05). In general, the results of this experiment showed that, given the lower price of guanidinoacetic acid compared to arginine, it is possible to effectively use 0.15% guanidinoacetic acid to replace arginine supplementation in preventing reduce stress.

This investigation was conducted to replace artificial food with Gammarus and study this effect on survival and growth parameters of jewel in case of completely randomized design with 3 treatments and 3 replicates in each treatments. 270 jewel fishes with initial mean weight of 1.22±0.72 were reared in 9 aquariums (30 fishes in each aquarium) with volume of 100 liter water. Experimental diets were including: 1) Gammarus 2) commercial pellet and Gamarus alternatively 3) commercial pellet (control diet). Fish were fed with the experimental diets to apparent satiation 4 times daily. At the end of experiment, growth parameters were estimated by the initial and final weight and hematology parameters were measured. Results showed significant differences for increased body weight and specific growth rate (P<0.05), but there were no significant differences for feed conversion ratio, conditional factor and survival rate between treatments (P>0.05). Increased body weight and specific growth rate was higher in control diet among treatments. Gammarus made significant differences on blood and biochemical factors such as hematocrit, hemoglobin, MCH, MCV, MCHC and triglyceride (P<0.05) but, red blood cells, white blood cells and total protein have not shown significant differences (P>0.05). Control diet had the higher value of hematocrit, hemoglobin, and triglyceride and lowest value of hematocrit and triglyceride was observed in Gammarus while hemoglobin was lowest in treatment 2. Diet containing commercial pellet and Gamarus alternatively had similar growth rate and some blood parameters than that of commercial pellet, so it could be useful for rearing ornamental fish and can considered as replacement by the part of commercial food, despite the fact that Gammarus could not cause to increase growth parameters as only feed.
