Background: Oxidative stress is a major contributor to diabetes, which can lead to testicular damage and infertility. Objective: This study aimed to compare the effects of metformin as a chemical drug with silymarin as an herbal agent on the sperm parameters and histopathological changes of testes in diabetic rats. Materials and Methods: Thirty-two male Wistar rats (250-270 gr) were randomly divided into four groups: 1) control; 2) diabetic; 3) diabetic+metformin 200 mg/kg; and 4) diabetic+silymarin 100 mg/kg. Daily injections were administered intraperitoneally for 56 days. At the end of the treatment, blood sampling was performed for biochemical assessment. Then, the rats were sacrificed and their left testis and epididymis were cut for sperm analysis as well as histopathology and morphometric evaluation. Results: Diabetes was associated with a reduced sperm count, motility, viability, maturity, and chromatin quality of sperm (p ≤ 0.001). It was also associated with a higher malondialdehide level and lower total antioxidant capacity level of serum in comparison with the control group (p ≤ 0.001). There was a significant difference in the seminiferous tubule diameter, germinal epithelium height, and testicular histopathological alterations in the diabetic rats compared with the control rats (p ≤ 0.001). Treatment with metformin and silymarin improved the above-mentioned parameters and this improvement was more substantial in silymarin-treated animals (p ≤ 0.001). Conclusion: In diabetic rats, metformin and silymarin improved sperm parameters, sperm DNA integrity, seminiferous tubule diameter, germinal epithelium thickness, and testicular histopathological complications; this improvement was more substantial in the silymarin-treated group. So, the findings of this study suggest that silymarin is more effective than metformin in treating diabetic-induced infertility. Key words: Diabetes, DNA damage, Metformin, Silymarin, Sperm, Testis.

Background: There is a growing interest in the correlation between antioxidants and periodontal disease. In this study, we aimed to investigate the effect of oxidative stress and the impact of two antioxidants, curcumin and rutin, respectively, in the etiopathology of experimentally induced periodontitis in diabetic rats. Methods: Fifty Wistar albino rats were randomly divided into five groups and were induced with diabetes mellitus and periodontitis: (1) (CONTROL)—control group, (2) (DPP)—experimentally induced diabetes mellitus and periodontitis, (3) (DPC)—experimentally induced diabetes mellitus and periodontitis treated with curcumin (C), (4) (DPR)—experimentally induced diabetes mellitus and periodontitis treated with rutin (R) and (5) (DPCR)—experimentally induced diabetes mellitus and periodontitis treated with C and R. We evaluated malondialdehyde (MDA) as a biomarker of oxidative stress and reduced glutathione (GSH), oxidized glutathione (GSSG), GSH/GSSG and catalase (CAT) as biomarkers of the antioxidant capacity in blood harvested from the animals we tested. The MDA levels and CAT activities were also evaluated in the gingival tissue. Results: The control group effect was statistically significantly different from any other groups, regardless of whether or not the treatment was applied. There was also a significant difference between the untreated group and the three treatment groups for variables MDA, GSH, GSSG, GSH/GSSG and CAT. There was no significant difference in the mean effect for the MDA, GSH, GSSG, GSH/GSSG and CAT variables in the treated groups of rats with curcumin, rutin and the combination of curcumin and rutin. Conclusions: The oral administration of curcumin and rutin, single or combined, could reduce the oxidative stress and enhance the antioxidant status in hyperglycemic periodontitis rats.

PURPOSE: To compare body weight and length, heart weight and length, heart-to-body weight ratio, glycemia, and morphometric cellular data of offspring of diabetic rats (ODR) and of normal rats (control). METHODS: Diabetes was induced in 3 pregnant Wistar rats, bearing 30 rats, on the 11th day after conception by intraperitoneal injection of 50 mg/kg of streptozotocin. Six normal pregnant Wistar rats, bearing 50 rats, made up the control group. Morphometric data were obtained using a scale for the weight, length, heart and body measurements. Morphometric cellular data were obtained by a computer assisted method applied to the measurements of myocytes. Statistical analysis utilized Student's t-test, ANOVA and Levene test. RESULTS: Control offspring had greater mean body weight and length than offspring of diabetic rats (p < 0.001). Heart weight and length and heart-to-body ratios of newborn rats differed between groups at birth (p < 0.001), but showed no difference at 21 days. Mean nuclei area and perimetric value of the myocytes decrees throughout the first 21 days of life (p < 0.01) in the diabetic group. CONCLUSIONS: Heart hypertrophy on the offspring of diabetic rats at birth was demonstrated by the significant difference between the groups. After the eleventh day, no difference was found, which confirmed regression of cardiomegaly. The significant difference between the first and the 21th day of life, for nuclei area feature, demonstrate regression of cardiac hypertrophy in the offspring of diabetic rats.

PURPOSE: Evaluate the cardiovascular and hematological effects produced by chronic treatment with two dosis of etoricoxib in Wistar normotensive rats. METHODS: Thirty rats have been used and divided into one control group and two etoricoxib (10mg/kg and 30mg/kg) treatments groups for 60 days. The mean arterial pressure (MAP) was taken during the whole experimental period and at the end of this period, under anesthesia blood samples were taken, and further the withdrawn of the aorta, heart, brain, liver, and kidneys for the anatomopathologic study. RESULTS: The treatment with etoricoxib (30mg/Kg) produced a significant increase of the MAP from the 28th day of the experiment and from the platelets when compared to the control group and to the group treated with 10mg/Kg, besides producing a highly significant difference in hematocrit and in the red blood cells in relation to the control group. On the other hand the treatment with etoricoxib has not caused histopathological changes when compared to the control. CONCLUSION: These data show that the chronic treatment with etoricoxib leads to increase of the MAP, and to important hematological changes which seem to be associated to the hemoconcentration although not producing anatomopathological significant changes.

Objective: To find out microscopically whether Trigonella foenumgraecum (fenugreek seeds/methi seeds) has got any preventive role against the lowering of cortical thickness of the thymic lobules in diabetes mellitus. Design: An experimental study on Long Evans rats which were divided into three equal groups depending on their different shorts of dietary feeding and drug treatment. Setting: Anatomy department of IPGMR (Institute of Post Graduate Medicine and Research) at present BSMMU (Bangabandhu Sheikh Mujib Medical University) and BIRDEM (Bangladesh Institute of Research and Rehabilitation in diabetes, Endocrine & Metabolic Disorders). Subjects: Fifty eight healthy young Long Evans rats of either sex weighing 72 to 174gm aged between 50 to 60 days were used in this study. Main outcome measures: Variation of cortical thickness of the thymic lobules in different groups of rat. Result: Cortical thickness in the nondiabetic control group, which ranges from 30.17 to 36.99. and the mean was 34.83 ± 0.60. In diabetic control group the cortical thickness ranges from 17.78 to 26.46 and the mean was 21.85 ± 1 On the other hand, in the fenugreek- treated diabetic rats the cortical thickness ranges from 25.71 to 32.95 and mean cortical thickness was 30.49 ± 0.75. Conclusion: Fenugreek showed a tendency of acting against lowering of the cortical thickness of the thymic lobule of Streptozotocin-induced diabetes mellitus. However, further investigations are recommended for establishing fenugreek as a safe, useful effective agent to preserve the cortical thickness improving the diabetic condition by acting as antidiabetogenic agent.

Infertility is one of the major health concerns in the world whose globally incidence rate is on the rise. Several hormones are effective in this process, such as testosterone, estrogen and Osteocalcin (OCN). The Osteocalcin has Gprc6a receptors on leydig cells, which promotes the production of testosterone when mounted on these receptors. Therefore, the aim of this study was to investigate the role of Osteocalcin on the improvement of spermatogenesis and expression of Gprc6a receptors on leydig cells in the azoospermic mouse model.Twenty-five mice (4 to 6 weeks) were randomly divided into five groups: control, sham I Group that was initially injected by busulfan solvent (DMSO) at 5 weeks old and then by Osteocalcin solvent (PBS) after 5 weeks for one month, azoospermia Group that received busulfan (40 mg/kg/ip) at 5 weeks old. Sham II Group received busulfan 40mg/kg/ipandt hen after 5 weeks received PBS and experimental group, including azoospermic mice, was administered by Osteocalcin (3ng/g/d) for one month. After the last injection, the tests were dissected and then exposed to the tissue passage. To measure morphological changes, H & E staining was performed on a number of sections to measure the diameter of the seminiferous tubule, thickness of the germinal layer, count the spermatogonial cells, spermatocyte, round spermatid, long spermatid, Sertoli, leydigandmyoid cells. Image J software was used to conduct quantitative studies. Immunohistochemical method was employed to examine the expression of the specific receptor of Osteocalcin, Gprc6α, in the Leydig cell among the groups.The H & E staining showed a significant difference in the count the spermatogonial cells, spermatocytes, round spermatids, long spermatids, the thickness of the germ layer, the seminiferous tubule diameter between the studied groups (P<0.05).There was also no significant difference in the count of Sertoli, leydig, myoid cells and seminiferous tubule diameter between the groups (P<0.05). In the immune histochemistry, no significant difference was found in the count of GpRC6α-positive leydig cells between the groups (P< 0.05).According to the current results, the OCN plays an important role in spermatogenesis, which has a positive effect on the count of spermatocytes and spermatids, and can be further explored as an appropriate therapeutic strategy proposed for the infertility.

Purpose:  To study the effects of Intra-vitreal injection of Bevacizumab as an adjunct during phacoemulsification in patients with diabetic retinopathy. Study Design:  Quasi experimental study. Methods:  Hundred diabetic patients who were scheduled to undergo phacoemulsification were included in the study. They were equally divided into two groups; Bevacizumab and control group. Complete ocular examination and macular thickness and volume were determined using an OPTOVUE-OCT machine. The patients in the Bevacizumab group were given intra-vitreal injection of 1.25 mg/0.05ml of Bevacizumab at the time of Phacoemulsification. A written ethical approval was obtained and the study was conducted according to principles of declaration of Helsinki. Results:  The bevacizumab group manifested low value of CMT one month post-surgery as compared to the control group (262.2 ± 32.2 and 288.5 ± 54.1, respectively) with P = 0.01. The Total Macular volume, and Best-corrected visual acuity in the two groups showed no significant difference one month after surgery. Amongst the patients who developed postsurgical macular edema, four patients did not possess a positive history for diabetic retinopathy and 3 of them had Non Proliferative Diabetic Retinopathy. We found no significant relationship between the post-surgical macula edema with the presence of mild Non Proliferative Diabetic Retinopathy. (Fisher's test, P = 0.321). Conclusion:  The ocular anti-VEGF therapy substantially reduces macular edema secondary to post-surgical inflammation in diabetic patients. It effectively reduces the central macular thickness although the results are not found to be statistically significant when compared with the control group. Key Words:  Diabetes mellitus; diabetic macular edema; diabetic retinopathy: Bevacizumab.

Objective: Methotrexate (MTX), is a commonly used chemotherapeutic agent. This study aimed to investigate the possibility that curcumin (CMN) protects against MTX-induced testicular damage by affecting the phospho (p)-p38 mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-kB) signaling pathways. Methods: Male Wistar albino rats were subdivided into three groups. The control group was given an intragastric (ig) administration of dimethyl sulfoxide (DMSO) daily for 14 days, the MTX group was given a single intraperitoneal (ip) dose of MTX (20 mg/kg) on the 11th day, and the MTX+CMN group was given ig CMN (100 mg/kg/day, dissolved in DMSO) for 14 days and a single ip dose of MTX (20 mg/kg) on the 11th day. Results: The animal weights, the seminiferous tubule diameter, and germinal epithelium height significantly decreased in the MTX group compared to the control group. The testes weight and the ratio of the testes to body weight did not change, whereas the number of seminiferous tubules and the interstitial space width increased significantly in the MTX group. The number of phospho-p38 (p-p38) MAPK immunopositive cells and the immunoreactivity of NF-kB also increased in the MTX group compared to the control group. Conclusion: CMN prevented the MTX-induced decreases in the body weight, seminiferous tubule diameter, and the germinal epithelium height, while significantly reducing the number of histologically damaged seminiferous tubules and the interstitial space width changes due to MTX. CMN also reduced the number of p-p38 MAPK immunopositive cells and the NF-kB immunoreactivity.

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.

The aim of this study was to describe the effects of nickel (NiCl2) on murine testicular structure. Experimental animals were injected intraperitoneally with a single dose of 20 mg NiCl2 per kg of body mass (group A, n = 5) and 40 mg NiCl2 per kg b. m. (group B, n = 5). The group without injection (n = 5) was the control (C). Animals were killed 48 hours after administration of nickel. The body mass of animals, the mass of testes and the testes : body mass ratio were not significantly affected. In both experimental groups a significant (p < 0.001) decrease of germinal epithelium in comparison with control group was observed. The relative volume of the interstitium was increased but not significantly in both experimental groups. An increase in the relative volume of the lumen was registered in both experimental groups in comparison with the control group. The qualitative analysis detected a dilatation of blood vessels in the interstitium, undulation of the basal membrane and several empty spaces in the germinal epithelium. The diameter (n = 150) of the seminiferous tubule was markedly (p < 0.05) decreased in both experimental groups (A, B) compared to control group. The height of the germinal epithelium showed a significant decrease (p < 0.05 - 0.001) after nickel administration. Evaluation of the lumen diameter in the seminiferous tubule showed a significant increase in both experimental groups. The data of the perimeter of seminiferous tubules corresponded with those of the seminiferous tubule diameter. TUNEL assay detected a higher frequency of localized apoptosis in the interstitium of nickel-administered animals compared to control group. Our findings clearly suggest a negative effect of nickel on the structure as well as on the function of the seminferous epithelium at the site of spermatozoa production.
