Diabetes and its complication continue to remain a concern in the world population despite the introduction of various hypoglycemic agents. Biochemical changes remain the major observable, clinical, and pathological factors as a derangement in the levels of these parameters increase the risk of developing complications. Although herbal extracts for the treatment of diabetes have been scientifically validated, the scientific interaction and alteration of the biochemical parameters due to the administration of this herbal product are not thoroughly investigated in this region. Therefore, this study aims to determine the effect of the extract of Kigeliaafricana and Sorghum bicolor stalk on the biochemical parameters of diabetic-induced rats. A total of eleven groups containing five rats per group of randomly selected Alloxan-induced Diabetes Healthy Wistar rats of both sexes were used in the study, with one serving as the control group, another serving as glibenclamide treated group, and the remaining nine, extract treated groups. After the overnight fast, the control group received a dose of 0.5 ml of 2% w/v acacia solution. Glibenclamide treated group received 600 μg/kg body weight (bwt) glibenclamide. In contrast, the other nine groups received specified doses (125, 250, and 500mg/kg bwt) of Kigeliaafricana and Sorghum bicolor extracts singly and in a mixture of ratio 1:1, respectively. After receiving the specified doses once a day orally for 30 days, the rats fasted overnight, and 5 ml of blood collected via cardiac puncture into heparinized and fluoride bottles. The samples were spun and separated for biochemical profiles (plasma glucose, lipid profile, liver function test, and electrolytes urea and creatinine) using a commercially prepared kit with outlined procedures. The result showed a significant decrease (p < 0.05) of plasma glucose level in the extract-treated rats, with a remarkable increase in untreated diabetic rats compared to the control. A significant reduction (p < 0.01) in the plasma levels of triglyceride and LDL-Chol was also observed in all treated groups at various doses of extracts compared to control with HDL-Chol values marginally increased in all extract-treated groups. Urea and creatinine showed a significant decrease (p < 0.01) in all treated doses except the lowest when compared to the control, while all the electrolytes parameters (Na+, K+, Cl- and HCO3-) show no significant difference (p > 0.05) across the groups when compared to the control. Liver function showed no significant differences in all parametersexcept for the noticeable decreasing effects on AST and ALT values compared to the control. The extracts and their mixture exhibited antidiabetic and hypolipidaemic activities and cardiovascular benefits due to their considerable lowering effects on total cholesterol, LDL-Chol, triglycerides, and increase in the HDL-Chol levels. The observed biological actions may be due to the presence of different phytocomponents present in the plant extracts. There is, therefore, a need to determine which of the active constituents has the main antidiabetic and hypolipidaemic effect for their optimal usage.

To investigate the influence of the pineal gland through melatonin secretion on the physiological and morphological parameters of pancreatic islets, we studied the plasma biochemistry and morphological and morphometric characteristics of the endocrine pancreas of male Wistar rats. The animals were distributed into five groups of ten rats each: NC - normal control group; NS - sham-operated group; Px (25) - pinealectomised group, studied 15-25 days after surgery; Px (70) - pinealectomised group, studied 60-70 days after surgery; ALX - alloxan monohydrate-treated group. Data are analyzed statistically by ANOVA and by the Kruskal-Wallis test. Although there was no significant difference in plasma glucose or insulin levels between the Px (25), Px (70) and NC groups, Px (25) animals showed a tendency to increased glucose and reduced insulin levels. The ALX group showed a clear elevation of plasma glucose and a reduction of plasma insulin compared to the other groups. Morphometric analysis showed a larger pancreatic islet area and a lower pancreatic islet density in the pancreas of Px (70) animals and an increase in degenerative pathological processes in the pancreatic islets of the Px (25) and ALX groups. The present results suggest that melatonin, in addition to acting on tissue sensitivity to insulin (as reported in other studies), affects the secretory action of beta cells, as demonstrated by the morphological and morphometric changes observed in pinealectomised animals.

Objectives Cats are commonly affected by chronic kidney disease (CKD). Many reactive carbonyl intermediates and end products originating from the oxidative stress pathways are recognised as uraemic toxins and may play a role in CKD progression. The aim of the present study is to confirm whether carbonyl end-product formation is higher in cats affected by CKD and to assess whether an angiotensin-converting enzyme inhibitor (ACEi) might affect these hallmarks. Methods Twenty-two cats were divided into three groups: a control group (CG), cats with CKD and cats with CKD treated with an ACEi. Serum levels of pentosidine, carboxymethyllysine, advanced oxidation protein products, malondialdehyde, methylglyoxal and hexanoyl-lysine were measured. In addition, biochemical parameters and systolic blood pressure were evaluated. After checking for normality, comparisons between groups were performed followed by multiple comparison tests. P values ⩽0.05 were considered significant. Correlations between concentrations of the considered biomarkers and of the other metabolic parameters were investigated. Results Advanced oxidation protein products, malondialdehyde and hexanoyl-lysine concentrations were significantly higher in CKD and ACEi-treated groups compared with the CG ( P <0.05). Carboxymethyllysine increased in the ACEi-treated group when compared with the CG, whereas intermediate values of these biomarkers were found in the CKD group ( P <0.05). The ACEi-treated group showed the highest values of carboxymethyllysine, advanced oxidation protein products and hexanoyl-lysine. By contrast, the CKD group had the highest concentration of malondialdehyde. No statistically significant difference was found in the levels of pentosidine or methylglyoxal. End products correlated with creatinine and urea and with each other. Conclusions and relevance Significantly high concentrations of both intermediate and end products of carbonyl/oxidative stress were detected in CKD cats. This is the first study to have concurrently taken into account several uraemic toxins and biochemical parameters in cats affected by CKD.

Aims Type 1 diabetes is a high-prevalent endocrine disease and causes oxidative stress in the testis tissue. In the treatment of diabetes, the tendency toward herbal medicines use is increasing. This study aimed to investigate the crocin effect on the Bax, Bcl2 (B-cell lymphoma 2), and anti-oxidant levels of streptozotocin-induced diabetic rats. Methods & Materials This experimental study was performed at Payam Noor University. In total, 24 rats were divided into 4 groups, as follows: control, untreated diabetic, and 2 crocin-treated (50, 100 mg/mL, 25 days intraperitoneal injection) diabetic groups. The diabetic groups were diabetic rats receiving the Intraperitoneal (IP) injection of Streptozotocin (STZ). On day 25, the testicles were dissected to evaluate antioxidant enzymes, Bax and Bcl2. The obtained results were analyzed in SPSS using one-way Analysis of Variance (ANOVA) and Least Significant Difference (LSD) test. Findings The pro-apoptotic Bax and malondialdehyde levels in the treated group with a concentration of 100 mg/mL of crocin was significantly reduced, compared to the treated group with a concentration of 50 mg/mL of crocin and the control group. However, the level of pro-apoptotic Bcl-2 and glutathione peroxidase, superoxide dismutase, and catalase enzymes in the treated group with a concentration of 100 mg/mL of crocin significantly increased, compared to the treated group with a concentration of 50 mg/mL of crocin, and the control group (P<0.05). Such finding indicates the effect of crocin concentration. Additionally, crosin significantly reduced the glucose level in diabetic rats. Conclusion Crocin improved the antioxidant indicators and diabetes-induced damages in the testis tissue of diabetic rats.

Background: Insulin, like most peptides, is classified as a hydrophilic and macromolecular drug that is considered as a low permeable and unstable compound in the gastrointestinal (GI) tract. The acidic condition of the stomach can degrade insulin molecules. Moreover, the presence of proteolytic activities of some enzymes such as trypsin and chymotrypsin can hydrolyze amide-bonds between various amino-acids in the structures of peptides and proteins. However, due to its simplicity and high patient compliance, oral administration is the most preferred route of systemic drug delivery, and for the development of an oral delivery system, some obstacles in oral administration of peptides and proteins including low permeability and low stability of the proteins in GI should be overcome. Objective: In this study, the effects of orally insulin nanoparticles (INPs) prepared from quaternerized N-aryl derivatives of chitosan on the biochemical factors of the liver in diabetic rats were studied. Methods: INPs composed of methylated (amino benzyl) chitosan were prepared by the PEC method. Lyophilized INPs were filled in pre-clinical capsules, and the capsules were enteric-coated with Eudragit L100. Twenty Male Wistar rats were randomly divided into four groups: group1: normal control rats, group 2: diabetic rats, group 3: diabetic rats received capsules INPs(30 U/kg/day, orally), group 4: the diabetic rats received regular insulin (5 U/kg/day, subcutaneously). At the end of the treatment, serum, liver and kidney tissues were collected. Biochemical parameters in serum were measured using spectrophotometric methods. Also, oxidative stress was measured in plasma, liver and kidney. Histological studies were performed using H and E staining . Results: Biochemical parameters, and liver and kidney injury markers in serum of the diabetic rats that received INPs improved significantly compared with the diabetic group. INPs reduced oxidative toxic stress biomarkers in serum, liver and kidney of the diabetic treated group. Furthermore, a histopathological change was developed in the treated groups. Conclusion: Capsulated INPs can prevent diabetic liver and oxidative kidney damages (similar regular insulin). Therefore oral administration of INPs appears to be safe. Lay Summary: Although oral route is the most preferred route of administration, but oral delivery of peptides and proteins is still a challenging issue. Diabetes Mellitus may lead to severe complications, which most of them are life-threatening. In this study, we are testing the toxicity of oral insulin nanoparticles in kidney and liver of rats. For this investigation, we will prepare insulin nanoparticles composed of a quaternized derivative of chitosan. The nanoparticles will be administered orally to rats and the level of oxidative stress in their liver and kidney will be determined. The data will be compared to the subcutaneous injection of insulin.

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.

ABSTRACT The polysaccharide fucoidin is a selectin blocker that inhibits leukocyte recruitment into the cerebrospinal fluid (CSF) during experimental pneumococcal meningitis. In the present study, the effect of fucoidin treatment on the release of the proinflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1 (IL-1), and IL-8 into the CSF was investigated. Rabbits (n = 7) were treated intravenously with 10 mg of fucoidin/kg of body weight every second hour starting 4 h after intracisternal inoculation of ∼106 CFU of Streptococcus pneumoniae type 3 (untreated control group, n = 7). CSF samples were obtained every second hour during a 16-h study period. Treatment with fucoidin caused a consistent and significant decrease in CSF IL-1 levels (in picograms per milliliter) between 12 and 16 h (0 versus 170, 0 versus 526, and 60 versus 1,467, respectively;P < 0.02). A less consistent decrease in CSF TNF-α levels was observed in the fucoidin-treated group, but with no significant difference between the two groups (P > 0.05). In contrast, there was no attenuation in CSF IL-8 levels. Indeed, there was a significant increase in CSF IL-8 levels (in picograms per milliliter) in the fucoidin-treated group at 10 and 12 h (921 versus 574 and 1,397 versus 569, respectively;P < 0.09). In conclusion, our results suggest that blood-derived leukocytes mainly are responsible for the release of IL-1 and to some degree TNF-α into the CSF during pneumococcal meningitis, whereas IL-8 may be produced by local cells within the brain.

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.

Aims. The aim of this study was to assess the efficacy and safety of timolol in the treatment of myopic regression after laser in situ keratomileusis (LASIK).Methods. We searched MEDLINE, CENTRAL, EMBASE, China National Knowledge Infrastructure (CNKI), and Chinese Biological Medicine (CBM) from the inception to July 2015 for relevant randomized controlled trials that examined timolol therapy for myopic regression. The methodological quality of the studies included was assessed using the Revman 5.3 software.Results. We included six clinical trials involving 483 eyes in this review, including 246 eyes in treated group and 237 eyes in controlled group. We observed statistically significant improvements on the postoperative SE in the 3 months. However, the change of CCT was not statistically different between the control group and the experimental group. There were fewer cases of IOP, UDVA, and CDVA in treated group having significant difference from the controlled group.Conclusions. Topical timolol could be an effective treatment for reduction of myopic regression especially the spherical errors after myopic LASIK. Further RCTs with larger sample sizes for these trials are warranted to determine the efficacy and limitation for myopic regression after LASIK.

The effects of fibre-enriched biscuit on biomarkers associated with hepatotoxicity in diabetic rats were investigated. Diabetes was induced by single intraperitoneal injection of alloxan monohydrate. Treatment lasted for 14 days after which the rats were sacrificed by cervical dislocation. Blood serum was analyzed to determine hepatic function enzymes. The liver was also analyzed to determine hepatic lipid profile and antioxidant enzymes. Induction of diabetes led to elevated levels of ALP, AST, and ALT. These were, however, significantly (p<0.05) reduced in the fibre-enriched biscuit fed (treated) group. There was no significant difference in the serum bilirubin and total protein levels of the studied groups. Reduced albumin level was observed in the diabetic group; this was further lowered on feeding with fibre-enriched biscuits. Induction of diabetes led to increased hepatic level of cholesterol, triglyceride (TG), low density lipoprotein (LDL), and lipid peroxidation and decreased activities of glutathione (GSH), catalase (CAT), and superoxide dismutase (SOD) and HDL level. These were significantly (p<0.05) reversed on feeding with fibre-enriched biscuit. This study portrays the protective effect of fibre-enriched biscuit on increased oxidative stress and hyperlipidemia in hepatic tissues of alloxan-induced diabetic rats.
