Abstract
Background: In this study, the effects of zinc oxide nanoparticles (ZnO NPs) and thiamine on the blood biochemical markers and kidney histopathological changes after experimental diabetes in mice was investigated.
Materials and Methods: For this purpose, 56 mice were randomly divided into 8 groups of 7 each. Two groups of animals as controls (A) and thiamine (G) were considered. Other groups were diabetic by alloxan at a dose of 180 mg/kg. Group B mice were considered as diabetic group. To diabetic mice into Group C and D , ZnO NPs in concentrations of 0.1 and 0.5 mg/kg were intraperitoneally injected. Groups E and F; to these groups of diabetic mice, ZnO NPs in concentration of 0.1 and 0.5 mg/kg along with thiamin (30 mg/l) was injected. ZnO NPs in concentration of 0.1 was injected to group H mice. Changes in renal tissue along with some biochemical parameters were measured.
Results: The results showed that diabetes induced changes in some of the serum biochemical factors (GGT, BUN and creatinine) in rats (p<0.05). However, the administration of nanoparticles and thiamine reduced these negative effects. Exposure to diabetes causes changes in the kidney tissue of the mouse, in the disturbance of scaffolds for tissue integrity clutter, fragmentation of some convoluted tubules and congestion within the connective tissue.
Conclusion: Treatment of the diabetes mice by ZnO NPs and thiamine improves renal histopathologic structure and blood biochemistry levels.

Abstract
Background and Aim: Diabetes is a well-known disease with such complications, as retinopathy, nephropathy, and gastropathy. This study aimed to investigate the effects of thiamine and lead acetate on the colon of induced-alloxan diabetic rats; the effects of which become obvious in the treatment or reduction of tissue complications caused by diabetes.
Methods & Materials: In this study, 63 rats weighing 200 g were divided into 9 groups, as follows: 1) Group of diabetes+pb acetate 200 ppm; 2) Group of thiamin+pb acetate 200 ppm; 3) Group of thiamine+pb acetate 1000 ppm; 4) Group of diabetes+thiamine+Pb acetate 1000 ppm; 5) Diabetes group; 6) Group of diabetes+thiamine; 7) Group of diabetes+thiamine+acetate 200 ppm; 8) Group of diabetes+pb acetate 1000 ppm, and 9) the control group. After 20 days, the study samples were removed from the abdominal cavity and the slides were prepared by routine tissue method. Then, the slides were evaluated for stereological and histomorphometric studies.
Ethical Considerations: This study was approved by the Faculty of Veterinary Medicine, Shahrekord University (Code: GRN1M1903). Moreover, all methods used in the present study, including facilitation, were conducted per the ethical principles of animal restraint.
Results: The mean thickness of mucosa-sub-mucosa suggested significant differences in groups 6 and 7, compared to other treatment groups. There was a significant difference in the thickness of the muscle layer between the control and all treatment groups except for groups 2, 6, and 7. There was no significant difference in the mean thickness of advantia layer in groups 1, 7, and 8, and the control group. The obtained results also indicated a significant difference concerning different layers of colon tissue between group 1 and controls.
Conclusion: Based on the present research results, thiamine presented enhancing effects on muscle layer thickness and adventitia layer thickness. Furthermore, the area of the mucosal layer was not affected by the improving effects of thiamine.

Abstract
Introduction: The study discusses the impact of thiamine on the tissues of rats that have been exposed to copper oxide nanoparticles. The research looks at how thiamine correlates with the level of kidney damage caused by the intrusion of nanoparticles.
Methods: In this experimental study, forty male Wistar rats aged 10 rats in each group were randomly divided into four groups. Two groups of rats were used as control group (I) and thiamine group (II). Rats of group III were administered intraperitoneal injection of 25 mg/kg body weight copper oxide nanoparticles for 14 days. Patients in group IV received the same dose of copper oxide nanoparticles together with thiamine (30 mg/kg body weight.
Results: The histopathological findings showed disruption of the order of convoluted tubules and their disintegration and widening of the tubular lumen, cell separation and tubular necrosis of the majority of the renal tubules in-group III. In the group treated with copper oxide nanoparticles along with thiamine (IV), the pathological changes were slight and the majority of the tubes had their normal structure. Statistically significant alteration in the levels of some serum biochemical parameters (catalase, superoxide dismutase, TBARS, and TAC) were observed in groups III and IV on day 14 when compared to the control group.
Conclusions: In this research, it was demonstrated that thiamine can be utilized as an effective compound to reduce the damage caused by nanoparticles in kidney tissue and can significantly improve the health of kidney tissue in patients suffering from damage caused by these nanoparticles.
