This study was planned to determine the effects of lycopene treatment on serum protein fractions in experimental diabetic rats. In order to induce diabetes in rats in the diabetes (D) and diabetes + lycopene (DL) groups, rats were given 45 mg/kg single-dose streptozotocin intraperitoneally. Lycopene (10 mg/kg/day dissolved in sunflower oil) was administered to the rats in the lycopene-only (L) and DL groups. Blood glucose levels and HbA1c% in DL group and diabetes group increased (p < 0.05) compared to control and L group. Total protein, albumin, α1, α2, and β globulin fractions of diabetic and DL groups were lower than control and L groups (p < 0.05). D group had lowest gamma (γ) globulin levels among other groups (p < 0.05). The γ globulin levels was slightly increased than diabetic groups (D and DL), but it was still lower than control and L groups (p < 0.05). The highest value of A/G ratio was observed in diabetic group. Similarly, the % level of A/G ratio of D group was higher than other groups. It was noted that the A/G ratio decreased and reached to control group levels after lycopene treatment.

The aim of this study was to determine the effects of Plantago major’s (P.major) water extract added into broiler diets at different levels on serum protein fractions. A total of 112 Ross 308 broiler chicks were used in the study. Experiment consisted of control and 3 treatment groups with a 28 chicks within each group. Each experimental group was divided into four subgroups consisting of 4 chicks. A basal (control) diet was prepared and three experimental diets were established by addition of P.major into basal diet; P.major 1 (5 g/kg feed), P.major 2 (10 g/kg feed), P.major 3 (15 g/kg feed). Broiler chicks were fed with these diets for 42 days ad libitum. Total protein levels of P.major 3 group were lower than other groups and controls. It was determined that the albumin percentages and levels became decreased in a significant ratio in the P.major 1 and P.major 2, (P<0,05), Alpha 1 globulin percentage and concentration were found significantly high in P.major 2 group than the other groups (P<0.05), Alpha 2 level and percentage in P.major 1 group was seen significantly higher than the control group, the A/G ratio in P.major 1 and P.major 2 was seen significantly lower than the control group. There was no significant difference between groups for beta and gamma globulins as percentage.

Background: Experimental diabetes can be induced using chemical agents such as streptozotocin Objective: This study aimed to investigate the effect of streptozotocin (STZ) which is most important agent to produce experimental diabetic model at two different doses on serum protein fractions in rat models. Materials and Methods: Twenty-four male rats that weighed an average of 250 g and were 3-4 months old were used as the experimental models. They were sorted into three groups composed of eight rats each of STZ 55 mg/kg, STZ 65 mg/kg and control. Diabetes was induced by administering STZ 55 mg/kg and 65 mg/kg intraperitoneally. The serum protein fractions were analyzed by cellulose acetate electrophoresis. Results: No significant difference was observed between the groups for all fractions except alpha-2 and beta globulins. The alpha-2 and beta globulin levels were significantly higher in the 55 mg/kg group than in the 65 mg/kg STZ and control groups (p<0.05). Conclusion: This increase may be due to the involvement of different proteins in the alpha-2 and beta globulin protein fractions.
