Puerarin mitigates oxidative injuries, opening of mitochondrial permeability transition pores and pathological damage associated with liver and kidney in Xanthium strumarium-intoxicated rats

In this study, the therapeutic effects of puerarin on Xanthium strumarium toxicity, which can develop in many species and does not have a specific antidote, were investigated. A single dose of 100 g/kg X. strumarium seeds was administered by gavage to female Sprague-Dawley rats, 6 h following which 200 mg/kg puerarin was administered by the same route, with puerarin administration being repeated daily at the same time. After completing the application, the blood, liver and kidney tissues of the rats were examined. Further, the biochemical parameters, glucose, MDA, GSH, SOD, mitochondrial Ca2+ and mitochondrial permeability transition pore (mPTP) opening levels, apoptotic factors (TUNEL, Bax and Bcl-2), ATP synthase and histopathological changes of the experimental rats were examined. The results revealed that while the administration of X. strumarium resulted in increased blood AST, ALT, ALP, LDH, CK, BUN and creatinine levels, it decreased glucose levels. In addition, it increased the MDA levels in the tissues and significantly increased the oxidative stress levels by decreasing the GSH levels and SOD activity. X. strumarium caused an increase in the mitochondrial Ca2+ and mPTP opening levels. Moreover, it increased the immunohistochemically determined ATP synthase expression and histopathologically identified necrotic liver cell death rates. Owing to its antioxidant properties and inhibitory effects on mPTP opening, puerarin administered for therapeutic purposes decreased the oxidative damage caused by X. strumarium toxicity, blood biochemical parameter levels, mitochondrial Ca2+ levels, mPTP opening, ATP synthase expression and the percentage of necrotic cells. Hence, the reduction in the liver and kidney damage in X. strumarium toxicity by puerarin indicates its potential use as an antidote for X. strumarium poisoning.

Upregulation of GLUT4 and PI3K, and downregulation of GSK3 mediate the anti-hyperglycemic effects of proanthocyanidins.

Diabetes mellitus is the most common chronic metabolic disorder worldwide. The present study was designed to investigate the potential role of cinnamon bark extract oligomeric proanthocyanidins (OPCs) in controlling streptozotocin (STZ)-induced hyperglycemia and to clarify the underlying molecular mechanisms underlying its effects. For this purpose, 60 male rats were equally divided into six groups as follows: The normal control group; OPC control group (non-diabetic rats treated with OPC at 300 mg/kg orally for 21 days); the untreated diabetic control group; the wortmannin control group [diabetic rats treated with wortmannin at 1 mg/kg, intraperitoneal (i.p.) on the final day of the experiment]; the OPC diabetic group (diabetic rats treated with OPC at 300 mg/kg orally for 21 days); and the OPC diabetic + wortmannin co-treated group (diabetic rats treated with OPC at 300 mg/kg/day for 21 consecutive days and then 24 h after the final OPC dose treated with a single wortmannin injection at 1 mg/kg, i.p.). The results indicated that OPC ameliorated the diabetic state, as evidenced by a significant decrease in serum glucose levels, and a significant increase in the levels of insulin, amylin, insulin receptor phosphorylation, glycogen and glucose transporter-4 translocation; it also improved the lipid profile in STZ-diabetic rats. On the whole, the findings of the present study provide biochemical evidence that OPC treatment is effective as an anti-diabetic and anti-hyperlipidemic agent by enhancing glucose uptake through the activation of insulin receptor kinase activity and the PI3K/Akt pathway.

Diabetes remission after a lifestyle-medicine intervention on type 2 diabetes in lean and obese Chinese subjects: a prospective study.

Whether diabetes remission still happened among non-obese type 2 diabetes (T2DM) patients with a body mass index (BMI) <25 kg/m2 following lifestyle-medicine interventions was quite necessary to be reported because many diabetes happened with normal or low BMI in China. The criteria for subject inclusion: <20 years after T2DM diagnosis, ≥6 months treatment with oral anti-diabetic drugs, without serious complications, and no history of insulin use. They were divided into two groups: the obesity group (BMI ≥25 kg/m2) and the lean group (BMI <25 kg/m2). All subjects received the following lifestyle-medicine interventions: stopping oral anti-diabetic therapy, initiating a low-carbohydrate (contributing by 35-40% to calorie intake) diet for the first month (gradual transition to a normal diet for the next 5 months), participating in resistance and aerobic exercise, and receiving strengthen management. Diabetes remission was defined as glycosylated hemoglobin (A1C) level <6.5% (<48 mmol/mol) after 6 months of not taking any anti-diabetic medications during the lifestyle-medicine intervention. Finally, 125 individuals completed the lifestyle-medicine intervention in the prospective study. The efficacy and safety of lifestyle-medicine intervention were assessed and compared between lean and obese Chinese subjects with T2DM. We found that 64.52% of the T2DM subjects in the obese group and 60.64% of T2DM subjects in the lean group achieved diabetes remission [i.e., an A1C level <6.5% (48 mmol/mol)] without any anti-diabetic medications after the 6-month lifestyle-medicine intervention. Our multiple linear regression analysis showed that decreases in the fasting plasma glucose (FPG) level had the most powerful effect on decreases in the A1C level after the intervention (R2=0.3072). Lifestyle-medicine interventions may have increased effectiveness in controlling mild T2DM as compared with the oral antidiabetic-based treatment; unexpectedly, there seems no further improvement in lean relative to obese patients. Three in five subjects could achieve diabetes remission though the lifestyle-medicine intervention regardless of whether their BMI was below or above 25 kg/m2.

Correlations of Salivary and Blood Glucose Levels among Six Saliva Collection Methods.

Background: Saliva has been studied as a better indicator of disorders and diseases than blood. Specifically, the salivary glucose level is considered to be an indicator of diabetes mellitus (DM). However, saliva collection methods can affect the salivary glucose level, thereby affecting the correlation between salivary glucose and blood glucose. Therefore, this study aims to identify an ideal saliva collection method and to use this method to determine the population and individual correlations between salivary glucose and blood glucose levels in DM patients and healthy controls. Finally, an analysis of the stability of the individual correlations is conducted. Methods: This study included 40 age-matched DM patients and 40 healthy controls. In the fasting state, saliva was collected using six saliva collection methods, venous blood was collected simultaneously from each study participant, and both samples were analyzed at the same time using glucose oxidase peroxidase. A total of 20 DM patients and 20 healthy controls were arbitrarily selected from the above participants for one week of daily testing. The correlations between salivary glucose and blood glucose before and after breakfast were analyzed. Finally, 10 DM patients and 10 healthy controls were arbitrarily selected for one month of daily testing to analyze the stability of individual correlations. Results: Salivary glucose levels were higher in DM patients than healthy controls for the six saliva collection methods. Compared with unstimulated saliva, stimulated saliva had decreased glucose level and increased salivary flow. In addition, unstimulated parotid salivary glucose was most correlated with blood glucose level (R2 = 0.9153), and the ROC curve area was 0.9316, which could accurately distinguish DM patients. Finally, it was found that the correlations between salivary glucose and blood glucose in different DM patients were quite different. The average correlation before breakfast was 0.83, and the average correlation after breakfast was 0.77. The coefficient of variation of the correlation coefficient before breakfast within 1 month was less than 5%. Conclusion: Unstimulated parotid salivary glucose level is the highest and is most correlated with blood glucose level, which can be accurately used to distinguish DM patients. Meanwhile, the correlation between salivary glucose and blood glucose was found to be relatively high and stable before breakfast. In general, the unstimulated parotid salivary glucose before breakfast presents an ideal saliva collecting method with which to replace blood-glucose use to detect DM, which provides a reference for the prediction of DM.

The Comparative Effects of Aqueous Extracts of Green Tea and Catechin on Inflammation, Apoptosis and Oxidative Stress in the Testicular Tissue of Diabetic Rats

Diabetes mellitus causes damage to testicular tissue through inflammation and oxidative stress. Catechin has been reported to have anti-oxidant and anti-inflammatory properties. This study was performed to compare the effects of aqueous extracts of green tea and catechin on inflammation, apoptosis and oxidative stress in the testicular tissue of type-1 diabetic rats. In this experimental study, 48 male Wistar rats were divided into control group, and diabetic rats treated with aqueous extract of green tea (100 and 200 mg/kg) and diabetic rats treated with catechin (100 and 200 mg/kg) (n = 6/each group) for 4 weeks. Diabetes was induced by an intraperitoneal injection of 240 mg/kg Aloxan. Levels of glucose, CRP, TNF-α, IL-1β and IL-6, SOD, CAT, GPX, MDA, Bax and Bcl-2 were measured by Elisa in testicular tissue. Histomorphometric changes in testicular tissue were evaluated using E&amp;H staining method. Treatment with aqueous extract of green tea (200 mg/kg) and catechin (100 and 200 mg/kg) resulted in a significant increase in Bcl-2, SOD, CAT, GPX levels and a significant decrease in serum glucose, Hs-CRP, TNF-α, IL-1β, IL-6, Bax and MDA levels, and significantly increased seminiferous tubules diameter and germinal cells count in testicular tissue compared to the diabetic control group. Treatment of diabetic rats with catechin had more improving effects on blood glucose, apoptosis, inflammation, lipid peroxidation, antioxidant enzymes, and histological structure of testis than green tea aqueous extract.

Relationship Of Serum Adiponectin Levels With Glycaemic Status In Pregnant Women.

Adiponectin plays an important role in glucose metabolism and released in response to insulin. It helps to decrease glucose levels and insulin resistance; however, this relation is not been studied in pregnant ladies. Objective was to determine serum adiponectin level and glycaemic status in pregnant women belonging to Peshawar, Khyber Pakhtunkhwa (KPK) and to find any possible relationship between them. Hundred pregnant women with gestational diabetes mellitus (GDM) and 100 healthy pregnant women without GDM were randomly selected in a cross-sectional study. After an overnight fast, their blood samples were taken for determination of serum adiponectin, glycosylated haemoglobin (HbA1c) and fasting blood glucose (FBG). The relationship of adiponectin with glycaemic status was determined with Pearson Correlations coefficient (r). Pregnant women with GDM when compared to healthy pregnant women showed significantly low levels of serum adiponectin (μg/mL) (2.2±0.2 vs. 11.25±4.8, p<0.05) and significantly high level of FBG (mg/dl) (182.7±64.2 vs. 93.6±5.9, p<0.05) and HbA1c (%) (7.4±0.1 vs. 5.4±0.1, p<0.05). Serum adiponectin level showed a statistically significant negative correlation with FBG (r = -0.203, p=0.042) and HbA1c (r = -0.744, p=0.000) in pregnant women with GDM. Serum adiponectin concentration is markedly decreased in pregnant women with GDM which concludes that Hypoadiponectinemia is related with deranged (elevated) glycaemic status in pregnancy. Moreover, adiponectin is associated negatively with FBG and HbA1c in the studied population.

Rest-activity circadian rhythm and impaired glucose tolerance in adults: an analysis of NHANES 2011-2014.

IntroductionCircadian rhythm disturbance occurs in type 2 diabetes, yet it is unknown whether it also exists in the prediagnostic phase of the disease. Thus, we examined the association of rest-activity circadian rhythm with 2-hour glucose levels and the risk of impaired glucose tolerance (IGT) in a nationally representative sample of adults without diabetes using a cross-sectional design.Research design and methodsWe analyzed data from 2760 adults without diabetes (age ≥20) with at least 4 days of validated accelerometer recordings and a valid oral glucose tolerance test from the National Health and Nutrition Examination Survey 2011–2014. Non-parametric rest-activity circadian rhythm parameters were derived from the accelerometer recordings.ResultsIn the models adjusting for multiple covariates, a one-quantile increase in relative amplitude (ie, increased circadian rhythmicity) was associated with 2.66 mg/dL decrease in 2-hour glucose level (95% CI −3.94 to −1.38, p<0.001) and a decreased odds of IGT (OR 0.75, 95% CI 0.63 to 0.89, p=0.002). A one-quantile increase in intradaily variability (ie, increased rhythm fragmentation) was associated with 3.01 mg/dL increase in 2-hour glucose level (95% CI 1.52 to 4.49, p=0.001) and an increased odds of IGT (OR 1.37, 95% CI 1.19 to 1.58, p<0.001).ConclusionsCircadian disruption is significantly associated with impaired glucose homeostasis in a general population of adults without diabetes. The association of circadian rhythm abnormalities with indicators of the pre-diabetic state suggests that circadian dysfunction may contribute to early disease pathogenesis.

Impact of DPP-4 inhibitors on plasma levels of BNP and NT-pro-BNP in type 2 diabetes mellitus

BackgroundDipeptidyl peptidase-4 inhibitors (DPP-4i) decrease glucose levels by regulating incretin peptides in type 2 diabetes mellitus (T2DM). This study aimed to determine the modulatory effect of DPP-4i on brain natriuretic peptide (BNP) and N-terminal pro-brain natriuretic peptide (NT-pro-BNP) in patients with T2DM.MethodsPubMed, Embase and the Cochrane Library were systematically searched to identify randomized controlled trials (RCTs) evaluating the impact of DPP-4i on BNP or NT-pro-BNP. A fixed- or random-effects model was used for quantitative analysis, according to the heterogeneity. Sensitivity analysis and publication bias were performed using standard methods.ResultsNine trials with 3056 patients with T2DM were included. Meta-analysis revealed that DPP-4i did not significantly modulate the BNP (0.21 pg/mL, 95% CI − 2.36–2.79) or NT-pro-BNP level (− 7.34 pg/mL, 95% CI − 24.27–9.59). DPP-4i demonstrated no stronger effect on modulating BNP (5.17 pg/mL, 95% CI − 7.48–17.82) or NT-pro-BNP (− 9.95 pg/mL, 95% CI − 44.61–24.71) than active comparators. Pooled analysis was robust and stable after sensitivity analysis.ConclusionsDPP-4i exhibits no significant effect on modulating BNP or NT-pro-BNP and shows no stronger effect than traditional antidiabetic agents in T2DM.

Introduction: Diabetes is a serious metabolic disorder and plenty of medical plants are used in traditional medicines to treat diabetes. These plants have no side effects, and many existing medicines are derived from the plants. The purpose of this systematic review is to study diabetes and to summarize the available treatments for this disease, focusing especially on herbal medicine. Methods: Scientific data bases were investigated for and screening through google engine for diabetes and effective plants informatics data. However, the investigation included Science direct, PubMed, Wiley, Scopus, and Springer. Out of the 100 collected articles (published in the period between 1997 and 2018). Results: Diabetes is mainly due to oxidative stress and an increase in reactive oxygen species that can have major effects. Many plants contain different natural antioxidants, in particular tannins, flavonoids, C and E vitamins that have the ability to maintain β-cells performance and decrease glucose levels in the blood. Conclusion: According to published results, it can be said that medical plants are more affordable and have less side effects compared synthetic drugs and are more effective in treatment of diabetes mellitus. Also order to harness these natural resources and maximize the socioeconomic benefits derivable from Sudanese medicinal plants efforts should be geared toward research funding and deployment of Research and Development (R &amp; D) policy framework into medicinal plants research endeavors.

Glucose deprivation using 2-deoxyglucose and acarbose induce metabolic oxidative stress and apoptosis in female mice bearing breast cancer

A characteristic of cancer cells is increased glucose uptake and glycolysis for energy production and hydroperoxide detoxification due to mitochondrial dysfunction. Thus, inhibition of glucose uptake and glycolysis represent smart novel therapy. We used 2-deoxyglucose (2DG) as a glycolysis inhibitor and acarbose (ACA), a specific alpha-glucosidase inhibitor, to decrease glucose uptake. Mice bearing mammary adenocarcinoma tumors were treated by 2DG and/or ACA. Relative tumor volume, tumor growth inhibition rate, relative body weight, glucose concentration, hexokinase-1 protein level by ELISA, pyruvate, and ATP (glycolysis products), reactive oxygen species (ROS), total glutathione T-GSH, apoptosis, and histopathology were measured in treated and untreated groups. Our results showed that combination therapy inhibited tumor volume and increased tumor growth inhibition rate, body weight reduction, decreasing glucose level, HK-1 level, and inhibition of glycolysis products. In addition, combination therapy induced oxidative stress, increase ROS, and decrease T-GSH. Furthermore, immunohistochemistry examination showed the broader area of apoptosis in breast cancer treated by combination agents. In conclusion, our result revealed that the novel combination inhibits glycolysis and glucose uptake and induced oxidative stress and apoptosis.

Discovery of (E)-4-styrylphenoxy-propanamide: A dual PPARα/γ partial agonist that regulates high-density lipoprotein-cholesterol levels, modulates adipogenesis, and improves glucose tolerance in diet-induced obese mice

Peroxisome proliferator-activated receptors are promising therapeutic targets for metabolic diseases, including obesity, diabetes, and dyslipidemia. This study describes the design, synthesis and pharmacological evaluation of stilbene-based compounds as dual PPARα/γ partial agonists with potency in the nanomolar range. In vitro and in vivo assays revealed that the lead compound (E)-4-styrylphenoxy-propanamide (5b) removed 14C-cholesterol from the foam cells through apolipoprotein A-I and High-Density Lipoprotein-2. In the high-fat diet-induced obesity mouse model, the oral administration of compound 5b increased HDL levels, paraoxonase-1 activity, and insulin sensitivity, and decreased glucose levels. Moreover, the adipogenesis pathway and triglyceride accumulation slightly changed in the adipocyte cells upon treatment with compound 5b, without affecting the body weight and adipose tissue in obese mice. Compound 5b did not affect the plasma levels of hepatic and renal injury biomarkers. Thus, stilbene-based compound 5b is a promising prototype for developing novel candidates to treat dyslipidemia and diabetes.

Effects of Isorhamnetin on Diabetes and Its Associated Complications: A Review of In Vitro and In Vivo Studies and a Post Hoc Transcriptome Analysis of Involved Molecular Pathways.

Diabetes mellitus, especially type 2 (T2DM), is a major public health problem globally. DM is characterized by high levels of glycemia and insulinemia due to impaired insulin secretion and insulin sensitivity of the cells, known as insulin resistance. T2DM causes multiple and severe complications such as nephropathy, neuropathy, and retinopathy causing cell oxidative damages in different internal tissues, particularly the pancreas, heart, adipose tissue, liver, and kidneys. Plant extracts and their bioactive phytochemicals are gaining interest as new therapeutic and preventive alternatives for T2DM and its associated complications. In this regard, isorhamnetin, a plant flavonoid, has long been studied for its potential anti-diabetic effects. This review describes its impact on reducing diabetes-related disorders by decreasing glucose levels, ameliorating the oxidative status, alleviating inflammation, and modulating lipid metabolism and adipocyte differentiation by regulating involved signaling pathways reported in the in vitro and in vivo studies. Additionally, we include a post hoc whole-genome transcriptome analysis of biological activities of isorhamnetin using a stem cell-based tool.

Porang (Amorphophallus oncophyllus) Flour Macerated with Strobilanthes crispus Reduced the Blood Glucose Levels of Streptozotocin-Induced Diabetic Rats

BACKGROUND: Diabetes mellitus (DM) is a group of metabolic diseases indicated by hyperglycemia. Dietary regulation represents a viable means of controlling blood glucose levels. Porang (Amorphophallus oncophyllus) is a local tuber that has a low glycemic index due to its high glucomannan content. In combination with Strobilanthes crispus (SC), which is rich in antioxidants, porang flour could be a promising treatment approach for DM. AIM: This study aimed to determine the effect of porang flour macerated with SC on the blood glucose levels of diabetic rats. METHODS: Thirty-five Wistar (Rattus norvegicus) rats were divided into five groups on the basis of their diets: Normal/negative control (NC) group (non-diabetic, standard AIN-93 diet), positive control (PC) group (streptozotocin [STZ]-induced diabetic), glibenclamide (GB) group (STZ-induced diabetic, medicated with GB 100 mg/200 g body weight [BW]), porang (NP) group (modified AIN-93 diet, fiber substituted with 11% porang flour [equal to 1.1 g/200 g BW]), and SC-macerated porang (SP) group (modified AIN-93 diet, fiber substituted with 11% porang flour macerated with SC [equal to 1.1 g/200 g BW]). The rats’ food intakes, stools, and BWs were recorded throughout the study, while their blood glucose levels were measured before the induction of DM, 3 days after the induction of DM, and at the end of the study (14-day treatment period). The data were statistically analyzed using a one-way analysis of variance combined with Duncan’s multiple range test. RESULTS: The rats’ feed intakes during the 14-day treatment period were almost the same, which influenced their BWs. After the induction of DM, the rats’ BWs appeared to decrease, albeit not to a statistically significant extent. This weight loss may have been better controlled in the treatment groups because the glucomannan content of the porang led to an improvement in the rats’ glucose metabolism, especially in the NP and SP groups. The rats’ stools appeared normal in consistency and moisture, and it was confirmed that there were no diarrhea incidents. The glucomannan content also decreased the blood glucose levels in the NP and SP groups. The SP group showed the best results in terms of decreased glucose levels due to the addition of SC as a source of antioxidants. CONCLUSION: Porang exerted an antidiabetic effect that was comparable with the effect of GB (a commercial drug). In combination with SC, it provided a high level of antioxidants. Porang should be further studied to optimize its antidiabetic potency and potential for use as a functional food or nutraceutical.

Exenatide challenge in oral glucose tolerance test is insufficient for predictions of glucose metabolism and insulin secretion after sleeve gastrectomy (SG) in obese patients with type 2 diabetes: a pilot study to establish a preoperative model to estimate β-cell function following augmented glucagon-like peptide-1 secretion after SG.

The postoperative increase in glucagon-like peptide-1 (GLP-1) is the main factor to improve glucose metabolism following sleeve gastrectomy (SG) in obese patients with type 2 diabetes. We investigated whether the β-cell responsiveness to an injection of exogenous GLP-1 in the preoperative period could determine the postoperative glucose tolerance in 18 patients underwent SG. In the preoperative period, a regular oral glucose tolerance test (OGTT) and an exenatide-challenge during OGTT (Ex-OGTT) were performed to evaluate the β-cell function and its responsiveness to GLP-1. The postoperative glucose tolerance was evaluated by another regular OGTT performed at 3 months after SG. The significant decrease in glucose levels with enhanced secretions of insulin and GLP-1 was observed in OGTT at 3 months after SG. The area under the curve of glucose from 0 to 120 minutes (AUC glucose0-120 min) and the insulinogenic index (I.I.) in OGTT at 3 months post-SG were significantly improved compared to those in preoperative period, but comparable with those in Ex-OGTT. AUC glucose0-120 min and I.I. in OGTT at 3 months post-SG were significantly correlated with not only those in Ex-OGTT, but also those in the preoperative regular OGTT. Conversely, the correlations calculated by the Spearman's ρ were stronger in the latter than the former. This exenatide-challenge protocol might be useful to estimate glucose tolerance and insulin secretion after SG, however, it may be insufficient to improve predictability of a patient who is likely to achieve a significant benefit on glucose metabolism from receiving SG.

Glycemic Control in Patients Undergoing Treatment With Paritaprevir/Ombitasvir/Ritonavir and Dasabuvir for Chronic Hepatitis C Infection.

Patients with hepatitis C virus (HCV)-associated cirrhosis are more prone to developing type 2 diabetes mellitus than patients with any other etiology of cirrhosis. The main objective of this study was to evaluate the impact of all oral antiviral treatment with ritonavir-boosted paritaprevir/ombitasvir and dasabuvir (OBV/PTV/r + DSV) in patients with chronic genotype 1b HCV infection. We retrospectively evaluated 806 patients who underwent antiviral therapy between December 2015 and July 2019. The laboratory data analyzed were liver function tests, kidney function tests, HCV viremia, fasting glucose levels, and glycosylated hemoglobin. Patients with impaired glucose metabolism were predominantly male and of older age compared to patients with normal glucose tolerance, and also had higher levels of transaminases. Proteinuria and higher creatinine levels were found in patients with impaired glucose metabolism. Overall, we found a 98.01% rate of sustained virologic response (SVR), with a non-significant difference between patients with normal and abnormal glucose metabolism. A statistically significant difference in SVR rates in patients with low degrees of fibrosis (F0-F2) versus those with advanced degrees of fibrosis (F3-F4) was found in both groups. Antiviral treatment resulted in significant decreases in fasting glucose levels and glycosylated hemoglobin levels in all patients with impaired glucose metabolism at SVR. Patients with pre-diabetes, as well as diabetic patients, achieved a better glycemic control after SVR obtained by ritonavir-boosted paritaprevir/ombitasvir and dasabuvir.

Phytochemical screening and antidiabetic effects of fruit rind of Momordica dioica roxb. on streptozocin induced type 2 diabetic rats

Momordica dioica (M. dioica) is a gourd like blooming plant that is readily available in Bangladesh, requiring biological research to discover its therapeutic values. The goal of our research was to see if the ethanolic extract of this plant had any anti-hyperglycemic properties. Water, glibenclamide and M. dioica extracts were fed to Streptozocin induced type-2 diabetic rat models at a dose of 1.25 g/kg body weight (bw) for 28 days to see what kind of effects they had on serum glucose, insulin, liver glycogen and lipid contents. Except for the control group, all the groups followed a pattern of maintaining the body weight. The oral glucose tolerance test was observed to be improved in extract after 14 days of the experiment. When assessed with the control group, the M. dioica extract showed a significant (p = 0.0015) decrease in postprandial serum glucose level (M±SD, mmol/l, 13.23 ± 1.03 control Vs 11.47 ± 2.21 extract) at 120 min. The treatment of diabetic model rats with extract resulted in a 7% (p < 0.0001) reduction in serum cholesterol levels. While subsequent 28 days of treatment, insulin levels were found to be lowered in all groups (from 246.76 to 200.44 pg/dL; p < 0.0001 for standard and from 309.01 to 204.61 pg/dL; p < 0.0001 for sample). The results revealed that prolonged administration of M. dioica improved the glycemic and lipidemic state of type-2 diabetic rats, implying that more research is needed to identify the active ingredient (s).

GAMBARAN HASIL PEMERIKSAAN KADAR GLUKOSA URIN PADA PENDERITA DIABETES MELLITUS DENGAN PENYIMPANAN DI LEMARI PENDINGIN SELAMA 24 JAM DAN TANPA PENYIMPANAN DI RS BANDUNG MEDAN

Glycosuria is where sugar (glucose) is excreted in the urine, even though blood sugar levels are low or normal. Glycosuria is a disease characterized by the presence of glucose in the urine. The disease is often also called diabetes or diabetes mellitus. Urine that is delayed for more than 2 hours will result in changes in its composition by germs because the collected urine sample is not accommodated in a clean and sterile container. This study aims to determine the urine glucose levels of patients with Diabetes Mellitus directly examined and stored 24 hours in a refrigerator at Bandung Hospital Medan using the Dip method. This study is descriptive in nature, where the population in this study is all people with diabetes mellitus from September to October 2021. The research sample was determined by Total Sampling. The results obtained from 10 positive urine glucose samples with the Dip method, all experienced a decrease in glucose levels when compared to direct examination. It is recommended that further research does not delay urine examination.

Prevention of diseases of the limbs in highly productive cows in the conditions of the industrial complex

The object of the study was cows of a black-and-white Holstein breed on tethered maintenance, housed in cowsheds of 200 animals each. Milk productivity per day averaged 36.2 kg per cow. The following main etiological factors of the occurrence and development of finger diseases were identified: violations of the conditions of keeping and feeding cows, lack of regular pruning and clearing of hooves, year-round stable maintenance and lack of exercise. When analyzing the biochemical composition of blood, it was revealed that the protein level in 67% of animals was higher than the normative indicators and was in the range of 89.7 - 91.2 g/l, the reserve alkalinity of blood serum in 86.5% of cows was reduced, which was 33.2 - 41.2 vol%, the ratio between albumins and globulins was violated. Also, 45.7% of the cows studied had a decrease in glucose levels in relation to the normative indicators. A set of measures for the prevention of diseases of the fingers in cows has been developed and its clinical effectiveness has been determined. A detergent and disinfectant called Compomol DS Step antipodermite is proposed for the rehabilitation of limbs in animals. This remedy has not only detergent -antiseptic properties against fresh wounds of the sole of the fingers, crumb, tissues of the arch of the interhoof slit and corolla, but also promotes rapid granulation of wounds, seals the horny wall of the hooves, forms a protective film with a long-lasting antimicrobial effect. The results obtained in production conditions indicate that the double use during the week of foot baths with a 5% solution of Compomol DS Step antipodermite reduces the incidence of limbs in cows by 26.3%, compared with the use of a 5% solution of copper sulfate.

EFFECT OF DIETARY SUPPLEMENTATION WITH ASTAXANTHIN ON THE HEMATOLOGICAL AND BIOCHEMICAL RESPONSE OF NILE TILAPIA (Oreochromis niloticus)

This study aimed to evaluate the effect of astaxanthin on the hematological, biochemical and somatic response of Nile tilapia ( Oreochromis niloticus ) orally administered in the feed for a period of 60 days. For the study, 105 tilapia (n=35) from the same spawn were used, constituting the following treatments: Control = animals (not treated with astaxanthin); T100 and T200 = fish treated with 100 and 200 mg of astaxanthin/kg of feed, respectively. There were no hematological alterations in red blood cells counts, hematocrit, hemoglobin, MCV and MCHC. In addition, astaxanthin-fed tilapia presented a better thrombocyte and leukocyte responses with a marked decrease in the number of thrombocytes, lymphocytes and neutrophils. Among treatments, there were no changes in serum levels of total protein, albumin, globulins, aspartate aminotransferase and alkaline phosphate. Treatment with astaxanthin resulted in a decrease in triglyceride and glucose levels, as well as increase in hepatosomatic indices. The results of hematological and biochemical analyzes of tilapias demonstrated the clinical safety of this carotenoid, not causing harmful effects to the health of fish. Therefore, the antioxidant activity of this compound in tilapias resulted in an improvement in the leukocyte profile and contributed to hypolipidemic effects at the dose of 200mg of astaxanthin/kg of feed.
