Saffron for 3000 years ago was valued as culinary condiment, dye, perfume and medicinal herb. The aim of research was to examine the effects of saffron supplementation on glucose levels, lipids and liver enzymes. In present study, the homogenate of saffron and saffron treated with chitosan was extracted after drying using 96% ethanol. Then, ethanol solvent was removed using rotary equipment. 60 Wistar rats (200-250g) were divided into six groups, including normal group, saffron group, saffron group treated with Chitosan, isoniazid group, isoniazid-saffron group and isoniazid-saffron group treated with Chitosan. For induction of oxidative effect, oral extract of saffron and saffron treated with chitosan was used as gavage. The DPPH method was used to compare the antioxidant effects of chitosan extract. The use of extract of saffron led to decreasing of triglyceride(31%), cholesterol(35%), LDL(22%), ALP(16%) and increasing of HDL levels until to 32%. Chitosan-treated saffron extract also led to decreasinf of LDL to 21%, ALT to 7% and increasing of HDL to 26%. In group receiving isoniazid and saffron, serum levels of enzymes of ALT(7%-16%), ALP(26%-69%), cholesterol(3%-31%), triglycerides(18%-44%) and glucose(4%-14%) showed a significant increasing compared to the control group. Therefore, considering these positive effects of saffron and chitosan-treated saffron, it is obvious the enhancing effects of the evaluated factors. Regarding the effects of saffron on blood glucose and triglycerides and also Liver enzymes, they have a positive effect on blood glucose and lipid control. The results of this study confirmed the undesirable effects of isoniazide on the cells of body.

This present resent study investigated sperm motility parameters (sperm motility duration and sperm motility percentage), spermatocrit, density of sperm and some biological factors such as sperm seminal plasma indices (ionic and organic composition) in 8 Acipenser ruthenus and Acipenser gueldenstaedti broodstocks. Sperm mobility duration length, percentage of sperm mobility, spermatocrit, density of sperm were measured 185±10.23 s, 90.00±2.25 %, 2.60±0.19 %, 2.42 × 0.30, respectively in A. ruthenus and 210±11.12 s, 90.33±2.16 %, 2.77±0.24 %, 2.63±0.18, respectively in A. gueldenstaedti. The concentrations of Sodium (Na+), Potassium (K+), Calcium (Ca2+) and Magnesium (Mg2+) ions were determined 88.56±7.24, 4.24±0.32, 7.52±0.29 and 2.38±0.26 Mm L-1, respectively in A. ruthenus and 90.84±6.12, 4.65±0.21, 7.31±0.34 and 2.44±0.31 Mm L-1, respectively in A. gueldenstaedti. The concentrations of serum cholesterol and glucose were calculated 48.74±5.46 and 27.90±2.57 mg ml-1, respectively in A. ruthenus and 47.53±4.22, 28.63±2.31 mg ml-1 respectively in A. gueldenstaedti. In addition, seminal plasma of A. ruthenus and A. gueldenstaedti were estimated 1.53±0.30 and 1.58±0.34 mg/dl protein, respectively. The results of this study showed that there is a significant difference between sperm motility duration in A. ruthenus and A. gueldenstaedti. No significant differences were observed between other biochemical and spermatological parameters in A. ruthenus and A. gueldenstaedti.

Purchase, transportation and maintenance of fish became and important chain in aquaculture industry along with the increase of farmers. Transporting of fishes is an stressful process in aquaculture. The present study investigate the effect of adding NaCl in transporting stress, on haematological parameters, blood serum biochemical parameters and skin mucus of Caspian white fish. For this purpose, along with the transporting fish to laboratory different concentrations of NaCl (0, 1, 3 and 6) were added to the trasnporting water. The samples of mucus and blood were taken immediately after transferring. Fish transferred to the seawater for one week and samples were collected after three days and one week. The result of this study showed that the RBC and hematocrit increased significantly over time after the salinity stress (P<0.05) and the amount of the hemoglobin, blood glucose and the total number of skin mucus bacteria decreased significantly over time after the salinity stress (P<0.05). However, there was no significant change in the amount of white blood cell, differential count of white blood cells, hemoglobin, mean volume of cell, the average concentration of cell hemoglobin and cortisol (P>0.05). Generally, it can be concluded that transported fishes with 1 g/litr salt in transporting water had better condition regarding immune parameters compared control group and other treatments.

This present resent study investigated sperm motility parameters (sperm motility duration and sperm motility percentage), spermatocrit, density of sperm and some biological factors such as sperm seminal plasma indices (ionic and organic composition) in 7 beluga (Huso huso) and Starry sturgeon (Acipenser stellatus) broodstocks. Sperm mobility duration length, percentage of sperm mobility, spermatocrit, density of sperm was measured 310±30.65 s, 93.11±4.31 %, 2.78±0.31 %, 2.76 × 109±0.36, respectively in beluga and 81±23.61 s, 80.63±3.27 %, 2.63±0.23 %, 2.40×109±0.28, respectively in A. stellatus. The concentrations of Sodium (Na+), Potassium (K+), Calcium (Ca2+) and Magnesium (Mg2+) ions were determined 96.24±8.47, 3.34±0.40, 8.66±0.44 and 1.15±0.15 Mm L-1, respectively in beluga and 95.33±8.40, 4.23±0.28, 8.43±0.47 and 2.39±0.24 Mm L-1, respectively in. The concentrations of serum cholesterol and glucose were calculated 12.98±6.77 and 32.67±2.47 mg ml-1, respectively in beluga and 45.68±5.78, 30.43±0.29 mg ml-1 respectively in A. stellatus. In addition, seminal plasma of beluga and starry sturgeon were estimated 1.45±0.27 and 1.49±0.29 mg/dl protein, respectively. The results of study indicated that mobility during length, percentage of sperm mobility and magnesium values had significant difference between beluga and A.stellatus sturgeon. The quality and quantity of sperm in Huso huso are higher than that in Acipenser stellatus. In addition, the magnesium in Acipenser stellatus level was significantly increased compared to Huso huso, but no significant differences were observed between both species.
