        Background & Aim: Type 2 diabetes is the most common endocrine disease that occurs due to glucose intolerance due to imbalance between reserves and insulin demand, which leads to be changes in liver enzymes with structural and functional changes in the liver. The aim of this study was to study changes in liver enzymes and insulin resistance index after HIIT and royal jelly in obese rats with type 2 diabetes. Materials & Methods: The statistical sample of the present study was 36 obese male rats with an average weight of 409 gr. After 20 weeks of high-fat diet, rats became diabetic by intraperitoneal injection of 25 mg/kg STZ body weight. Mice with fasting glucose between 150 and 400 mg /dl were considered to have type 2 diabetes. Diabetic rat in 4 groups of control (N=6), HIIT (N=8), royal gel (N=7), HIIT& Royal gel (N=8) group done and Accomplished Eight weeks of HIIT, 5d/w with intense 2-minute intervals of 80 to 90% VO2max and one-minute rest intervals with 50 to 56% VO2max. Royal jelly was given by gavage at the rate of 100 mg / kg 5 days a week. At the end of the protocol, blood samples were taken and liver enzymes and glucose were measured using an auto-analyzer and insulin was measured using a laboratory kit and analyzed using one-way and two-way analysis of variance and post hoc test. Results: showed that in comparison with the control group, HIIT led to a significant decrease in glucose and insulin resistance index and intermittent exercise resulted in a decrease in liver enzymes ALT, AST and ALP compared to the control group. The ALP decrease was significant (P = 0.001). Conclusion: It seems that HIIT and consumption of royal jelly can help reduce liver enzymes and improve liver status in rats. Manuscript profile

        This research was conducted in order to study the effect of taurine amino acid addition on performance, carcass characteristics, blood factors and liver enzymes in broilers. The experiment was conducted in 45 days in the form of a completely random design with 300 pieces of one-day-old broilers of the Ras strain, including 4 treatments, 5 repetitions and 15 birds in each repetition with the same energy and protein diets with the same rearing conditions. The experimental treatments included: the first treatment (basic diet) and the second, third and fourth treatments respectively: the basic diet along with 1 g/kg taurine amino acid, 3 g/kg taurine amino acid and 6 g/kg taurine amino acid. The results showed that body weight gain, feed consumption and food conversion ratio were significant between the experimental treatments and the control treatment during the breeding period (P0.05). But numerically, a better performance was observed with the addition of taurine supplement to the diet in these enzymes. (P > 0.05). In general, the results of this experiment showed that adding 6 grams/kg of taurine amino acid leads to an improvement in the titer of blood parameters and liver enzymes without negatively affecting the performance and characteristics of the carcass.

        4 - The Effect of Different Levels of Dietary Manganese on Antioxidant Activity, Liver Enzymes and Liver Histology in Reared Young Beluga (Huso huso)

        This research aims to determine the effect of different amounts of dietary manganese on antioxidant activity, liver enzymes and, liver tissue of rearing young beluga (Huso huso) from October to December 2022 at the Dr. Beheshti Reproduction and Genetic Stock Restoration Center of Sturgeon in Rasht, Guilan province. For this study, 180 pieces of beluga with an average initial weight of 266 ± 3.05 grams underwent a two-week adaptation period in the breeding environment, in six treatment groups and each treatment with three repetitions, with concentrations of 5 (Mn1), 10 (Mn2), 15 (Mn3), 20 (Mn4) and 25 (Mn5) mg of manganese sulfate monohydrate (MnSO4H2O) per kilogram of food and control treatment (Mn0) without adding manganese sulfate supplement were carried out in two months. At the end of each month, three pieces of fish were selected from each repetition, blood was collected and their livers were sampled for histological studies. The results revealed a significant difference in catalase and glutathione peroxidase levels among the experimental treatments (p<0.05) and their maximum amount was the control treatment fish, while superoxide dismutase levels did not differ significantly (p<0.05). Among the liver enzymes, Alkaline-phosphatase and aspartate-aminotransferase had a significant difference between the control treatment and other experimental treatments (p<0.05), but the alanine-aminotransferase enzyme had no significant difference (p<0.05). Also, different forms of tissue damage were observed in the liver tissue of all treatments, even the control (atrophy, biliary stagnation, Fat degeneration and, cellular necrosis). Based on the results of this research, the levels of 10-15 mg of dietary manganese could improve antioxidant activities, liver enzymes and reduce liver tissue damage in breeding young beluga.

        A total of 288 Ross 308 broiler chickens (mixed sex) were used to investigate the effect of supplemental guanidino acetic acid (GAA) to soybean meal (SBM) and canola meal (CM) based diets on growth per-formance, carcass characteristics, liver enzymes, and morphometric indexes. Birds were randomly assigned to four treatments in a completely randomized design with a 2 × 2 factorial arrangement consisting of 2 types of oil seed meal (SBM and CM) and 2 levels of GAA (0 and 0.6 g/kg) with six replicates in each. The results indicated that birds fed with CM diet had significantly lower feed intake and body weight gain and a worse feed conversion ratio than those fed with SBM diet (P<0.05). Supplementing GAA to the CM diet but not to the SBM diet led to increased feed intake so that the value was similar to those birds receiving the SBM diet as a statistical point (P<0.05), while the improvement of body weight gain was not achieved completely. Carcass, breast, and thigh yields were statistically lower in birds fed the CM diet than those fed the SBM diet, while the abdominal fat and liver weight were higher (P<0.05). Neither type of oil seed meal nor GAA significantly affected the liver enzymes and nitric oxide concentrations, as well as gut mor-phometric indexes (P<0.05). It can be concluded that supplementing 0.6 g/kg GAA to the CM-based diet to some extent improves the growth performance of broiler chickens, and more content may be needed for complete improvement.
