Study design: Experimental randomized cross-over study. Animals: Forty male Sprague-Dawley rats (body weight 200-300 g) were used in this study. Methods: Four 1.0% lidocaine solutions were prepared from commercially available solutions. The treatment 1(n=10 rats) was lidocaine hydrochloride, treatment 2 was combination of lidocaine and borate buffer, treatment 3 (n=10 rats) was lidocaineepinephrine, treatment 4 (n=10 rats) was lidocaine-epinephrine-borate buffer. each treatment was received 0.1 ml of the agent using a 27-G needle connected to an insulin syringe injected around the sciatic nerve. Time to the onset and duration of the superficial and deep analgesia were recorded and analyzed. The results were expressed as mean ±SD and were analyzed by a one-way analysis of variance and Duncan test as a post hoc for time of onset and duration of analgesia. Graphpad Prism version 5 software program was used for all analyses. Results: Alkalinization of 1.0% lidocaine with or without epinephrine by borate buffer produced a faster onset than lidocaine or the combination of lidocaine and epinephrine. Conclusion and clinical relevance: We conclude that the injection of lidocaine with added borate buffer and 1: 100,000 epinephrine increases the duration of analgesia and reduces the onset of blockade in the rat model.

Triplicate groups of 15 fish in nine fiberglass tanks held under identical culture conditions (temperature, aerated, dissolved oxygen and photoperiod) were fed three times a day. Three diets were formulated to replace the dietary fish oil containing the same protein level 43% and fat levels of 14% by canola oil (100% fish oil, 100% canola oil and 50% fish oil 50% canola oil). Fish fed with 50% fish oil and 50% canola oil diets had significantly different growth performance compared with other treatments (p<0.05). Feed conversion ratio was significantly different in all treatments with the highest FCR value in 100% fish oil treatment (p<0.05). There was no significant difference on survival rate, carcass protein, fat and moisture. Levels of liver enzymes (Lactate dehydrogenase and Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase) were significantly higher in 100% fish oil than other treatments. Canola oil improved the immune system and enzymes including ALP, AST, ALT and LDH. Based on the obtained results it can be inferred that replacing 50% fish oil with 50% canola oil in the diet was a suitable for Caspian brown trout which not only had positive effects on growth indices but also can reduce feed formulation costs.

The aim of this study was to evaluate the effectiveness of nanocomposite tricalcium phosphate (TCP)/collagen scaffolds combined with hydroxyapatite scaffold for bone healing in surgery of femoral defects in rabbits. In this study, 45 mature male New Zealand white rabbits between 6 and 8 months old and weighting between 3 and 3.5 kg were examined. Rabbits were divided into three groups. Surgical procedures were performed after intramuscular injection of Ketamine 10% (ketamine hydrochloride, 50 mg/kg) and Rompun 5% (xylazine, 5 mg/kg). Then an approximately 6 mm diameter-5 mm cylinder bone defect was created in the femur of one of the hind limbs. After inducing the surgical wound, all rabbits were coloured and randomly divided into three experimental groups of 15 animals each. Group 1 received pure medical nanocomposite TCP/collagen granules, group 2 received hydroxyapatite, and third group was a control group which received no treatment. Histopathological evaluation was performed on days 15, 30, and 45 after surgery. On days 15, 30, and 45 after surgery, the quantity and the velocity of stages of bone formation at the healing site in nanocomposite TCP/collagen group were better than HA and control groups and the quantity of newly formed lamellar bone at the healing site in nanocomposite TCP/collagen group were better than onward compared with HA and control groups. In conclusion, it seems that TCP/collagen nanocomposite has a significant role in the reconstruction of bone defects and can be used as scaffold in bone fractures.

There are large differences among countries in the rate of growth and development of aquaculture. This review tries to explain the progress and problems of aquaculture during three last decades in Iran. The total production of Iran from aquaculture was 25,800 tons in 1994, approximately 8 percent of the total fisheries production. However, by 200 8 it increased to more than 154,000 tons; 27% of total fisheries production. During the last decade, production share of different species in Iran has been variable. In the years 1998 and 2008 the highest percentage of aquaculture production was belonged to silver carp Hypophthalmichthys molitrix (50%) and rainbow trout (Oncorhynchus mykiss; 40%), respectively. The results showed that culture of rainbow trout has grown noticeably in the past two decades. At present, Iran has b...

This project has been proposed to collect the excess sperm of Caspian Sea Southern part sturgeon breeders, to cryopreserve and hold them for further use. During two spawning seasons (2006-2007), sperm quality and quantity analysis were conducted on 34 different male sturgeons of which 12 Persian sturgeon, 4 stellate sturgeon, 1 beluga and 1 ship sturgeon with better quality were chosen to cryopreserve. After dilution of fresh sperm with sturgeon sperm diluent (115 mM Tris, 23.4 mM sucrose and 15% DMSO) at the ratio of 1:1, the 0.5 ml straws were filled using special filling and sealing apparatus and frozen with a multi step freezing rate. To access the further quality and fertilization test, samples were thawed at 40 °C for 20 seconds. During the project performance, 1010 ml of Persian sturgeon sperm , 110 ml of ship sturgeon sperm , 90 ml of stellate and 80 ml of beluga sperm were cryopreserved. The reduction of frozen-thawed sperm motility in comparison with fresh samples showed 10-52.3 % decrease, but there was not any significant differences between samples after 7 months preservation in liquid Nitrogen (P < 0.005). River caught Persian sturgeon samples showed higher sperm density in comparison with nonriverine breeders (P < 0.05). Data showed that stellate sturgeon sperm showed better resistance to freezing condition in comparison with Persian sturgeon spermatozoa. Fertilization tests (4 hours after fertilization)showed 27.4% and 58.2% fertilization rate in frozen-thawed stellate and Persian sturgeon spermatozoa, respectively.

Belugas (120±10g) were fed on diets containing 0, 25, 50, 75, and 100 ppb AFB 1 /kg of diet for 3 months. Results showed various levels of AFB 1 do not significantly affect the specific growth ratio (SGR) (P<0.05) of fish in different treatments. However, weight gain and food conversion ratio (FCR) were varied significantly (P<0.05 between control and treatments with diets contaminated with 75 and 100ppb AFB 1 /kg after 90 days). The increase AFB 1 level of did not affect on the percent of survival rate(SR) and no mortality was observed in treatments (SR=100%) suggesting that various AFB 1 levels under experimental conditions of the present study affect some growth factors, such as, weight gain and FCR but have no significant impact on SR and SGR. Histopathological studies showed that different level of AFB 1 can cause broad range of change in liver tissue, including progressive fat deposition, hepatocyte degeneration and necrosis, particularly at concentration of 75 and 100ppb AFB 1 /kg of diets after 60 days.

The fish larvae (50 ± 4.5 mg) were fed diets containing 0 (control), 5, 10, and 20 mg/kg thiamine for 26 days from 18 days after hatching to 44 days after hatching. Thiamine significantly increased the larvae survival, growth rate, digestive enzymes activity, and whole body protein and ash but decreased the whole body lipid and moisture P < 0.001 ). Also, alanine amino transferase (ALT) and alkaline phosphatase (ALP) were decreased significantly in thiamine-treated groups ( P < 0.05 ). The highest survival and whole body ash were observed in 20 mg/kg thiamine treatment; the highest whole body protein and lipase activity were observed in 10 mg/kg thiamine treatment. The highest growth rate, amylase, and lowest whole body lipid, alanine amin...
