Anti-Quorum Sensing and Anti-Biofilm Activity of Ginger (Zingiber officinale) Rhizomes against Multidrug-Resistant Clinical Isolates of Pseudomonas aeruginosa.

Background: The aim of this study was to determination of Anti-Quorum Sensing (AQS) and anti-biofilm potential of the methanol extract of ginger (Zingiber officinale) rhizomes against multidrug-resistant clinical isolates of Pseudomonas aeruginosa (P. aeruginosa). Methods: The AQS activity of ginger was determined against Chromobacterium violaceum (C. violaceum) ATCC 12472 (CV12472), a biosensor strain, in qualitative manner using the agar well diffusion method. The violacein pigment inhibition was assessed to confirm AQS activity of ginger. The AQS potential of sub-minimum Inhibitory Concentrations (sub-MICs) of the ginger extract was determined by targeting different QS regulated virulence factors, including swarming motility (using swarm diameter measurement method), pyocyanin pigment (using chloroform extraction method), Exopolysaccharide (EPS) (using phenol-sulphuric acid method), and biofilm formation (using microtiter plate assay), against clinical isolates (CIs 2, 3, and 4) and standard reference strain of P. aeruginosa (PA01). Results: The AQS activity of methanol extract of ginger was confirmed against C. violaceum (CV12472) as inhibition of violacein pigment formation without effecting the growth of CIs and PA01 of P. aeruginosa. The ginger extract exhibited concentration-dependent inhibition of virulence factors and biofilm formation. The maximum reduction was found in swarming motility, pyocyanin, EPS and biofilm formation against PA01 (51.38%), CI3 (57.91%), PA01 (63.29%) and CI2 (64.37%), respectively at 1/2 MIC of ginger extract. Conclusion: The results of present study revealed the effective AQS and anti-biofilm potential of Zingiber officinale rhizome methanol extract at a reduced dose (sub-MICs). The extract may be explored as an agent of antimicrobial compounds having AQS and anti-biofilm activity for controlling microbial infection and also for reducing the chances of emergence of resistance in P. aeruginosa.

Antibacterial Activity of Selected Fruit Juices against Multidrug-Resistant Bacterial Pathogens Involved in Urinary Tract and Sexually Transmitted Infections among Tribal Women in Madhya Pradesh, India.

Objectives: The aim of this study was to evaluate the effect of fruit juices on Multi-Drug Resistant (MDR) bacterial pathogens involved in Urinary Tract Infections (UTIs) and Sexually Transmitted Infections (STIs) among tribal women in the district Anuppur, Madhya Pradesh, India. Methods: Fresh juices of lemon (Citrus limon), amla/Indian gooseberry (Phyllanthus emblica), pineapple (Ananas comosus), mosambi/sweet lime (Citrus limetta), orange (Citrus sinensis), kiwi (Actinidia deliciosa), and pomegranate (Punica granatum) fruits were evaluated for in vitro antibacterial activity against bacterial pathogens involved in UITs and STIs among tribal women. Physico-chemical analysis of fresh fruits was also carried out by measuring the pH, moisture, protein, fat, crude fibre, carbohydrate, and ascorbic acid content. Results: Lemon and amla juice showed better antibacterial activity against the pathogens as compared to other juices. MIC results fruit juices against UTIs and STIs pathogens vary depending on the specific pathogen and juice chemical constituents. The physico-chemical analysis showed that the moisture content was highest in mosambi (90%), followed by orange (87%). Ascorbic acid content was found highest in amla (540 mg/100 g), followed by kiwi (90.3 mg/100 g). Pomegranate showed highest concentration of carbohydrate (15.28 g/100 g), fat (1.28 g/100 g), and protein (1.65 g/100 g). Lemon juice had lowest pH of 2.20, followed by amla 2.67. Conclusion: The lemon juice showed highest antibacterial activity against MDR bacterial pathogens involved in UTIs and STIs among tribal women in district Anuppur, Madhya Pradesh, India. The low pH of lemon may be responsible for its high antibacterial activity as compared to other juices.

Suppression of SlDREB3 increases leaf ABA responses and promotes drought tolerance in transgenic tomato plants.

Drought susceptibility is a major yield limiting factor in agricultural crops especially in hybrids/varieties that have been bred for high yields. We show that manipulation of the SlDREB3 gene in tomato alters ABA responses and thereby sensitivity of stomatal closure to ABA. SlDREB3 suppression lines show ABA hypersensitivity and rapid stomatal closure in response to ABA while over-expression lines show reduced sensitivity to ABA and open stomata even at high ABA levels with rapid water loss after 10 days of water stress. This is accompanied with high ROS levels and increased membrane damage due to senescence of leaves and drastically reduced survival in drought. The relative water content (RWC) of OEx lines is much reduced even when grown under well-watered conditions. In contrast, suppression lines show greater tolerance to water stress and almost complete survival to 10-day water stress. They show much reduced ROS levels, reduced membrane damage, higher RWC and reduced leaf water loss. These changes are associated with higher expression of ABA signalling pathway genes in suppression lines while these are highly reduced in OEx lines. The studies suggest that control of ABA signalling by SlDREB3 can help in withstanding severe drought.

Patient Perspectives and Outcomes in Adult Hypospadias Repair.

Background Hypospadias is a common congenital anomaly that needs repair at an early age (six months to one year). Ironically, many cases in India present late due to a lack of healthcare facilities, poverty, and illiteracy. Adult patients are different from children as they are aware of their genitalia. They are concerned with the aesthetics and, predominantly, the potency. In this study, we present the perspectives and outcomes of 111 adult cases of hypospadias. Methodology In this retrospective study conducted between January 2010 and December 2020, 111 patients aged more than 14 years who were diagnosed with hypospadias of any level with or without mild-to-moderate chordee were included. Hypospadias repair using a tubularized incised plate (TIP) urethroplasty technique was performed, and patients after surgery were followed up at three months, six months, and 12 months for any complications with physical examination, uroflowmetry, and patient-related outcomes (PROs). Results Age varied from 14 years to 32 years (mean = 19.88 years, SD = 5.93). The most frequent meatus positions after chordee adjustment were distal (n = 64, 57.65%), middle (n = 25, 22.52%), and proximal (n = 22, 19.82%). Among these, four patients had penoscrotal transposition. Chordee was present in 65.7% (n = 73) of the cases. (<30° in 38.7%, n = 43; 30°-60° in 23.4%, n = 26, and >60° in 3.6%, n = 4). Chordee was corrected using many techniques, including ventral corporotomies. Urethroplasty was done using TIP and spongioplasty in 89% (n = 99), and one patient underwent inner preputial onlay flap urethroplasty. Snodgraft was used to augment the urethral plate in 10 cases. The success rate of one-stage surgery was 74.77% in our series, which significantly correlated with PROs. Uroflow varied from 12 mL/second to 18 mL/second, and in the majority of the cases, the flow rate improved over time. The most common complication was urethrocutaneous fistula in 11 (11.8%) patients, followed by glanular dehiscence in nine (8.1%) patients. Conclusions Adult patients undergoing primary hypospadias repair generally show good outcomes. Patients can have an acceptable mild degree of residual chordee and torsion, which correlate well with PROs. In our series, hypospadias fistula was the most common complication of hypospadias surgery, followed by glanular dehiscence.

Testosterone propionate and Swarna Bhasma treatment modulated D-galactose induced reproductive alterations in male Wistar rats: An experimental study.

Background: The male reproductive system undergoes several adverse age-related changes like decreased hormone synthesis, sperm count, and testicular alteration that can impact on fertility. Objective: The study aims to investigate the effects of testosterone propionate (TP), and ayurvedic formulation Swarna Bhasma (SB) on D-galactose (D-gal) induced reproductive aging in male Wistar rats. Materials and Methods: 60 male Wistar rats were divided into 10 groups of 6 animals. Reproductive aging was induced by D-gal (150 mg/kg Bwt) exposure for 60 days. The rats were then treated by post and combination treatment with TP (2 mg/kg Bwt) and SB (6.75 mg/kg Bwt). Then sperm parameters, reproductive hormones, inflammatory markers, testicular antioxidant enzymes, steroidogenic enzymes, and histological manifestation of testis were evaluated. Results: Exposure of D-gal caused significant (p < 0.001) decrease in serum testosterone (T), testicular steroidogenic, and antioxidant enzymes. Administration of TP increased the serum T level, testicular antioxidant enzymes, and spermatogenic profile at a significant level of (p < 0.001) compared to D-gal. Further, the SB treatment significantly (p < 0.001) elevated the serum T level, sperm count, testicular antioxidant enzymes, steroidogenic enzymes, when compared to D-gal. Conclusion: Both the treatment of TP and SB treatments recovered the reproductive impairments caused by D-gal. However, exogenous T supplementation via TP administration is associated with various side effects during long-term use. SB is an Ayurvedic formulation having a long history of usage in India. The current findings suggest that the SB may be used as a good alternative for potentiating reproductive function in aging males.

Intelligent control of integrated on-board charger with improved power quality and reduced charging transients.

This paper proposes an intelligent control scheme for a two-stage integrated onboard electric vehicle (EV) battery charger connected to a single-phase household outlet which offers a close to ideal battery charging profile with power factor correction feature. Generally, the front-end AC-DC​ conversion stage is controlled by dual loop proportional-integral (PI) controllers, and tuning their gain constants is a difficult task. Furthermore, to achieve a close to ideal charging profile for an EV battery, the DC-DC conversion stage switches from constant current (CC) and constant voltage (CV) mode after a certain state of charge (SOC) which may lead to discontinuity in the charging current and voltage. This paper attempts to solve these issues by proposing an intelligent control scheme that includes the dynamic estimation of PI controller gain constants as well as provides a seamless mode transfer feature for battery charging. It is achieved by using fuzzy-PI-based control in the AC-DC conversion stage and Bayesian Regularization (BR) algorithm trained artificial neural network (ANN)-based control in the DC-DC conversion stage. The performance of the proposed control scheme is assessed both in steady-state and transient conditions in MATLAB® Simulink environment by comparing it against similar control schemes. The proposed intelligent control approach improves the dynamic response of DC link voltage, offers unity power factor operation and maintains the line current harmonics within IEEE 519 standards even during the switchover from CC to CV charging mode. Also, there is a decrease of 85% in the third harmonic component of the source current, 23.2% improvement in DC link voltage undershoot and 6.5% reduction in DC link voltage overshoot with reduced settling times using the proposed unified control scheme.

Inhibition of Quorum Sensing Regulated Virulence Factors and Biofilm Formation by Eucalyptus globulus against Multidrug-Resistant Pseudomonas aeruginosa.

Objectives: The quorum-sensing-inhibitory and anti-biofilm activities of the methanol extract of E. globulus leaves were determined against clinically isolated multidrug-resistant Pseudomonas aeruginosa. Methods: The preliminary anti-quorum-sensing (AQS) activity of eucalyptus was investigated against a biosensor strain Chromobacterium violaceum ATCC 12472 (CV12472) by using the agar well diffusion method. The effect of sub-minimum inhibitory concentrations (sub-MICs) of the methanol extract of eucalyptus on different quorum-sensing-regulated virulence factors, such as swarming motility, pyocyanin pigment, exopolysaccharide (EPS), and biofilm formation, against clinical isolates (CIs 2, 3, and 4) and reference PA01 of Pseudomonas aeruginosa were determined using the swarm diameter (mm)-measurement method, chloroform extraction method, phenol (5%)-sulphuric acid (concentrated) method, and the microtiter plate assay respectively, and the inhibition (%) in formation were calculated. Results: The preliminary AQS activity (violacein pigment inhibition) of eucalyptus was confirmed against Chromobacterium violaceum ATCC 12472 (CV12472). The eucalyptus extract also showed concentration-dependent inhibition (%) of swarming motility, pyocyanin pigment, EPS, and biofilm formation in different CIs and PA01 of P. aeruginosa. Conclusion: Our results revealed the effectiveness of the E. globulus extract for the regulation of quorum-sensing-dependent virulence factors and biofilm formation at a reduced dose (sub-MICs) and suggest that E. globulus may be a therapeutic agent for curing and controlling bacterial infection and thereby reducing the possibility of resistance development in pathogenic strains.

Antibacterial efficacy of different combinations of clove, eucalyptus, ginger, and selected antibiotics against clinical isolates of Pseudomonas aeruginosa.

BACKGROUND: Nosocomial infections caused by multidrug-resistant Pseudomonas aeruginosa are commonly treated with conventional antibiotic which may lead to some serious side effects in the patients. Conventionally, medicinal plants, including clove, eucalyptus, and ginger, are used for the safe and effective treatment of several diseases. AIMS AND OBJECTIVES: The aim and objective of this study is to evaluate the combined antibacterial efficacy of medicinal plants (clove, eucalyptus, and ginger) and selected antibiotic and also combined efficacy of different plants extracts against clinical isolates of P. aeruginosa. MATERIALS AND METHODS: A total of seven clinical isolates and one reference strain (PA01) of P. aeruginosa were included in this study. The antibacterial activity of crude methanol extracts of medicinal plants and selected antibiotics was screened using well-diffusion assay and their minimum inhibitory concentration (MIC) was determined by the microdilution method. Combined efficacy of ceftazidime and plant extracts was tested using standard checkerboard method and different plant extracts were evaluated using broth macrodilution method. RESULTS: All of the seven clinical isolates of P. aeruginosa showed multidrug resistance pattern and were found highly sensitive to ciprofloxacin followed by ceftazidime and gentamicin. Clove exhibited better antibacterial activity as compared to eucalyptus and ginger. Synergistic interaction was found between ceftazidime and plants extracts against reference PA01 and clinical isolate 2. Highest two-fold reduction in MIC was found in the combination of clove-ginger against reference PA01 and clinical isolate 3. CONCLUSION: The selected medicinal plants are highly efficient for enhancing the antibacterial activity of antibiotic.

Predictors of Presenting Seizures in Acute Cerebral Vein and Dural Sinus Thrombosis.

BACKGROUND AND PURPOSE: Risk of seizure is significantly higher in cerebral vein and dural sinus thrombosis (CVST) compared to other stroke subtypes. There is paucity of literature on predictors of presenting seizures in CVST. This study was designed to investigate the risk and predictors of seizures in CVST at presentation. METHODS: Total 181 consecutive patients with CVST were retrospectively analyzed. RESULTS: Total 181 patients with CVST were enrolled (age range, 14 to 96 years; mean age, 34.64±14.66 years). A total of 44 patients had presenting seizures. Younger age (p=0.028), involvement of superficial cortical veins (p=0.016), presence of hemorrhagic venous infarct (p≤0.001) and involvement of frontal lobe (p≤0.001) were significantly related to the presenting seizures on the univariate analysis. The hemorrhagic venous infarct (odds ratio [OR], 4.44; 95% confidence interval [CI], 1.89-10.44; p=0.001) and involvement of the frontal lobe (OR, 10.66; 95% CI, 4.02-28.29; p≤0.001) were independently associated with the presenting seizures on the multivariate analysis. CONCLUSIONS: About one fourth of the patients with CVST had presenting seizures. The patients with hemorrhagic venous infarct in the frontal region are more prone to have presenting seizures.

Acetylation of Response Regulator Proteins, TcrX and MtrA in M. tuberculosis Tunes their Phosphotransfer Ability and Modulates Two-Component Signaling Crosstalk.

Two-component signal transduction (TCS) cascades involve stimulus-dependent activation and phosphorylation of a sensor kinase (SK), which then transfers the phosphoryl moiety to the response regulator (RR) protein. The fidelity of this phosphotransfer reaction from the SK to the RR provides specificity to TCS signaling. In the present study, we show that for TcrX, a transcriptionally autoregulated RR of Mycobacterium tuberculosis, acetylation enhances its net phosphorylation from cognate SK TcrY and lowers it from a non-cognate SK MtrB. Similar acetylation mediated increase in phosphorylation was also observed for another RR MtrA from cognate SK MtrB. Thus, we establish a novel TCS signaling design wherein acetylation of RRs results in enhanced cognate phosphorylation and suppresses non-cognate phosphorylation. Using wild-type or acetylation-deficient TcrX proteins in M. tuberculosis H37Ra, we demonstrate that non-acetylated TcrX acts as a "phosphate sink" for MtrB and suppressing signal propagation from MtrB to MtrA in vivo, linking metabolism to TCS signaling. Overall, we report that acetylation of RRs shields TCSs from crosstalk, modulates the phosphatase activities and alters the DNA-binding activities of RRs, all of which are non-intuitive behavior of TCS systems.

In vitro and in vivo Assessment of Protein Acetylation Status in Mycobacteria.

Protein acetylation is one of the standard post-translational modifications found in proteins across all organisms, along with phosphorylation which regulates diverse cellular processes. Acetylation of proteins can be enzymatically catalyzed through acetyltransferases, acetyl CoA synthetases or non-enzymatically through acyl carrier metabolic intermediates. In this protocol, using response regulator proteins as targets we describe the experimental strategy for probing the occurrence of acetylation using purified recombinant proteins in an in vitro setup. Further using M. smegmatis strains overexpressing the wild type or mutant response regulator protein, we also describe how in vivo acetylation can be validated in Mycobacterial proteins. The described approach can be used for analyzing acetylation of any mycobacterial protein under both in vitro and in vivo conditions.

Clinical Presentation, Neuroimaging Findings, and Predictors of Brain Parenchymal Lesions in Cerebral Vein and Dural Sinus Thrombosis: A Retrospective Study.

INTRODUCTION: Cerebral venous sinus thrombosis (CVST) is an unusual cause of stroke with potentially serious consequences. This study was designed to investigate the clinical and neuroimaging features in patients with CVST and to analyze the predictors of brain parenchymal lesions. MATERIALS AND METHODS: A retrospective study of 181 patients with CVST was conducted in a tertiary care hospital. RESULTS: Of 181 patients (age range 14-96 years, mean age: 34.64 ± 14.66 years), 121 were female (66.9%). Most of the patients were in their third decade of life. Headache (47.51%) was the most common clinical presentation followed by seizures (24.31%). Transverse sinus (TS) (77.9%) was the most common site of venous sinus thrombosis. Brain parenchymal lesions were present in 63%, and each patient had subarachnoid and intraventricular hemorrhage. Hemorrhagic venous infarct was the most common brain parenchymal lesion (37.57%). Frontal region (25.4%) was the most common site of brain parenchymal lesions followed by frontoparietal region (21.9%). Women were more likely to have brain parenchymal lesions (72.4%, P = 0.034). Headache was the most common clinical presentation in patients without brain parenchymal lesions while seizures with brain parenchymal lesions. Straight sinus thrombosis was more likely to be associated with brain parenchymal lesions (P = 0.009). CONCLUSION: CVST presents in young and more commonly in females. TS was the most common site of venous sinus thrombosis. Female gender, seizures, altered sensorium and focal neurological deficit at presentation, and straight sinus thrombosis were more likely associated with the presence of brain parenchymal lesions.

GLP-I secretion in healthy and diabetic Wistar rats in response to aqueous extract of Momordica charantia.

BACKGROUND: Diabetes mellitus is one of the major global health disorders increasing at an alarming rate in both developed and developing countries. The objective of this study was to assess the effect of aqueous extract of Momordica charantia (AEMC) on fasting blood glucose (FBG), tissue glycogen, glycosylated haemoglobin, plasma concentrations of insulin and GLP-1 hormone (glucagon-like peptide 1) in healthy and diabetic wistar rats. METHODS: Male Wistar rats (both normal and diabetic) were treated with AEMC by gavaging (300 mg/kg body wt/day for 28 days). RESULTS: AEMC was found to increase tissue glycogen, serum insulin and GLP-1 non-significantly (P > 0.05) in normal, significantly (P < 0.01) in diabetic Wistar rats, whereas decrease in FBG and Glycosylated haemoglobin non-significantly (P > 0.05) in normal, significantly (P < 0.01) in diabetic Wistar rats. The elevation of GLP-1 level in normal and diabetic treated groups may be due to the L-cell regeneration and proliferation by binding with L-cell receptors and makes a conformational change, resulting in the activation of a series of signal transducers. The polar molecules of M. charantia also depolarize the L-cell through elevation of intracellular Ca2+ concentration and which in turn releases GLP-1. GLP-1 in turn elevates beta-cell proliferation and insulin secretion. CONCLUSION: The findings tend to provide a possible explanation for the hypoglycemic action of M. charantia fruit extracts as alternative nutritional therapy in the management and treatment of diabetes.

Curcumin and Quercetin Ameliorated Cypermethrin and Deltamethrin-Induced Reproductive System Impairment in Male Wistar Rats by Upregulating The Activity of Pituitary-Gonadal Hormones and Steroidogenic Enzymes.

BACKGROUND: Dietary antioxidants protect tissues and organs against insecticides/xenobiotic-induced damage. In the present study, we evaluated the results of exposure to synthetic pyrethroid insecticides, cypermethrin (Cyp) and deltamethrin (Del) and possible protective effects of curcumin and quercetin on reproductive system in male Wistar rats. MATERIALS AND METHODS: In this controlled experimental study, 42 male Wistar rats were randomly divided into 7 groups of 6 animals. Group A served as control, group B was exposed to Cyp (2 mg/kg.bw), group C was exposed to Del (2 mg/kg.bw), group D was exposed to Cyp+Del (2 mg/kg.bw each), group E was exposed to Cyp+Del and treated with curcumin (100 mg/kg.bw), group F was exposed to Cyp+Del and treated with quercetin (100 mg/kg.bw) and group G was exposed to Cyp+Del and treated with quercetin+curcumin for 45 days. RESULTS: Exposure to Cyp and Del caused decreases in reproductive organs weight, sperm count, sperm motility, level of sex hormones viz. testosterone (T), follicle stimulating hormone (FSH) and luteinizing hormone (LH), steroidogenic enzymes viz. 3ß-hydroxyl steroid dehydrogenase (3ß-HSD) and 17ß-HSD, non-enzymatic antioxidant glutathione (GSH) and enzymatic antioxidants viz. superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST) and glutathione reductase (GR) activity and increases in sperm abnormalities and lipid peroxidation (LPO). The exposure also adversely affected the histo-achitecture of testes. Single and combined treatment with curcumin and quercetin significantly ameliorated Cyp and Del-induced damage in reproductive system. CONCLUSION: Curcumin and quercetin protected against Cyp and Del-induced reproductive system toxicity and oxidative damage in rats. The increases in activities of 3ß-HSD and 17ß-HSD with concomitant increases in testosterone were mainly responsible for ameliorating effects of curcumin and quercetin. Curcumin showed slightly better activity as compared to quercetin. The combination of both antioxidants offered more protection compared to each one alone.

MRI findings of Persistent Mullerian Duct Syndrome: A Rare Case Report.

Embryologically mullerian duct derivatives lead to formation of female genitalia and wolffian duct derivatives to male genitalia. Presence of mullerian duct derivatives in a chromosomally normal male (XY) leads to male pseudohermaphroditism and is referred to as Persistent Mullerian Duct Syndrome (PMDS). A young male patient with bilateral cryptorchidism presented to our hospital who was subsequently imaged. There are many case reports of persistent mullerian duct syndrome but they focus mainly on surgical aspects. In this article, MRI features of persistent müllerian duct syndrome are presented.

Administration of Lactobacillus casei and Bifidobacterium bifidum Ameliorated Hyperglycemia, Dyslipidemia, and Oxidative Stress in Diabetic Rats.

BACKGROUND: The present work was planned to evaluate the antihyperglycemic, lipid-lowering, and antioxidant effect of Lactobacillus casei and Bifidobacterium bifidum in streptozotocin (STZ)-induced diabetic rats. METHODS: Single daily dose of 1 × 10(7) cfu/ml of L. casei and B. bifidum alone and in combination of both was given to Wistar rats orally by gavaging for 28 days. Glucose tolerance test, fasting blood glucose (FBG), lipid profile, and glycosylated hemoglobin (HbA1c) were measured from blood. Glycogen from thigh muscles and liver and oxidative stress parameters from pancreas were analyzed. RESULTS: Administration of L. casei and B. bifidum alone and in combination of both to diabetic rats decreased serum FBG (60.47%, 55.89%, and 56.49%, respectively), HbA1c (28.11%, 28.61%, and 28.28%), total cholesterol (171.69%, 136.47%, and 173.58%), triglycerides (9.935%, 8.58%, and 7.91%), low-density lipoproteins (53.27%, 53.35%, and 52.91%) and very low-density lipoproteins (10%, 8.58%, and 11.15%, respectively) and increased high-density lipoproteins (13.73%, 15.47%, and 15.47%), and insulin (19.50%, 25.80%, and 29.47%, respectively). The treatment also resulted in increase in muscle (171.69%, 136.47%, and 173.58%) and liver (25.82%, 6.63%, and 4.02%) glycogen level. The antioxidant indexes in pancreas of diabetic rats returned to normal level with reduction in lipid peroxidation (30.89%, 46.46%, and 65.36%) and elevation in reduced glutathione (104.5%, 161.34%, and 179.04%), superoxide dismutase (38.65%, 44.32%, and 53.35%), catalase (13.08%, 27%, and 31.52%), glutathione peroxidase (55.56%, 72.23%, and 97.23%), glutathione reductase (49.27%, 88.40%, and 110.86%), and glutathione-S-transferase (140%, 220%, and 246.6%, respectively) on treatment with L. casei, B. bifidum, and combination treatment. CONCLUSIONS: Administration of L. casei and B. bifidum alone and in combination of both ameliorated hyperglycemia, dyslipidemia, and oxidative stress in STZ-induced diabetic Wistar rats.
