RESUMO
This research is carried out to explore the hypoglycemic activity of Syzygium cumini seed extracts by in vitro, in vivo, and in silico methods. For in vitro studies the α-amylase and α-glucosidase enzyme inhibition assays were employed. For in vivo studies 30 alloxan induced Wistar rats were used. They were orally administered with glibenclamide and low/high dose of the extracts and were monitored regularly for the change in blood glucose levels for about 28 days. The in silico molecular docking was conducted to evaluate the binding interaction of 1,2,3-Benzenetriol with human pancreatic α-amylase and α-glucosidase. It was found that all the extracts were able to inhibit the α-amylase and α-glucosidase enzymes. Among which the acetone extract showed greater inhibition with 72.52 ± 0.51% and 63.02 ± 0.73% for both the enzymes, respectively. There was significant (p < 0.05) reduction in blood glucose levels in the rats administered with glibenclamide and extracts. In silico docking results revealed that the compound 1,2,3-Benzenetriol exhibited the highest binding affinity for human pancreatic α-amylase with binding energy -7.7 kcal/mol. Thus suggesting the utilization of S. cumini seeds in the management of diabetes mellitus.Communicated by Ramaswamy H. Sarma.
RESUMO
Antibiotics are choice of drugs in patients with respiratory infections. Irrational use of antibiotics is an important public health issue faced on daily basis by the community and the individual. Keeping this in consideration, the current study investigates the prescription pattern of antibiotics in lower respiratory tract infection in general population.The objectives of the study include prescription pattern analysis of antibiotics for LRTIs in general population and to evaluate adherence to antibiotic treatment. This was a hospital based prospective observational study conducted between November 2021 to April 2022 in the department of general medicine and pediatrics. Compliance to various antibiotics was scrutinized by using MMAS 4 scale. Patient demographics, laboratory details, prescribed antibiotics, duration of hospital stay were gathered over a period of 6 months.A total of 200 patients were involved in the study, out of which 53% were males and 47% were females. A total of 2127 drugs were prescribed in 200 patients (10.6 drugs/prescription). Ceftriaxone was the most commonly used antibiotic followed by azithromycin and piperacillin/tazobactam. The most frequently diagnosed disease was Bronchopneumonia (41%) followed by A/E COPD (28%). Evaluation of medication adherence resulted in 58% high and 11% poor adherence. The number of antibiotics prescribed was found to be rational but prevalence of polypharmacy should be prevented. Medication adherence decreases as the frequency of antibiotic increases, so it is recommended to lower the frequency of drugs as possible to enhance the compliance.
RESUMO
The aim was to study the prevalence of comorbidities in rheumatoid arthritis (RA) patients in everyday clinical practice and their association with disease-specific and demographic factors. The multi-center study recruited 3,247 (at 14 centers, and 265) were excluded due to incomplete data. The number of subjects considered for the analysis was 2982. The mean (±standard deviation) age was 48.98±12.64 years and the male-to-female ratio was 1:5. The data was collected based on a pre-structured pro forma by trained clinical research associates through interview and verification of charts and reports available in the patient records. The following comorbidities were studied: cardiovascular disease, hypertension, diabetes mellitus, hypercholesterolemia, thyroid disease, psychiatric diseases like depression, and pulmonary disease. Hypertension (20.7%), diabetes mellitus (14.4%) and thyroid disease (18.3%) were the most prevalent comorbidities. Hypercholesterolemia (5.3%), pulmonary diseases (2.1%), cardiovascular diseases (0.2%) and depression (0.03%) were prevalent in ≤5% of the study population. The overall presence of comorbidity increased with age and reduced with the duration of illness prior (DOIP). The age, gender, and DOIP differed significantly between groups with and without hypercholesterolemia. Females had a statistically increased prevalence of thyroid disease. The prevalence of comorbidities in RA patients from south India is around 40% and the incidence of comorbidity increased with age. As per the literature evidence, the prevalence in the current study subjects was higher when compared to prevalence of similar diseases occurring in the general south Indian population.

OBJECTIVE: Photovaporization of prostate (PVP) is a newer surgical modality of benign prostatic hyperplasia (BPH) which is gaining importance recently. There are a few randomized controlled trials that showed safety and efficacy of PVP in comparison with transurethral resection of prostate (TURP) with limited follow-up period (<2 years). Here, we are presenting a comparative study performed on potassium titanyl phosphate (KTP) PVP laser versus TURP for the treatment of BPH with long-term follow-up period. MATERIAL AND METHODS: After institutional ethical clearance, 150 patients were prospectively included in the study from January 2010 to March, 2012. Improvement of International Prostate Symptoms Score (IPSS), Qmax, post-void residual (PVR) urine, International Index of Erectile Function (IIEF)-5 score and complications were assessed at 12, 24, 36 and 48 months. RESULTS: Mean age of the study group was 65.3±7.86 years in the TURP and 63.6±8.12 years in the PVP groups (p=0.45). IPSS symptom score improved significantly in both TURP and KTP groups (p<0.003). There was improvement in Q max during follow-up in both groups (p<0.001) which was maintained at 48 months. Most of the patients in both groups were satisfied with symptoms and bothersome at 48 months. All the sexual parameters are similar to both groups except retrograde ejaculation. Overall complication noted in 23 patients (15.33%). CONCLUSION: Both KTP Laser PVP and TURP afford durable relief from symptoms of BPH at 48 months follow-up. Both procedures are safe and associated with minimal complications. Both procedures do not have any detrimental effect on sexual function on long-term follow-up. Quality of life remains high even at 4 years in both groups.

INTRODUCTION: Vascular endothelial growth factor A (VEGFA) and its kinase insert domain receptor (VEGFR2/KDR) were reported to be upregulated in chronic myeloid leukemia (CML); however, the influence of polymorphisms in VEGFA and VEGFR2 in CML pathogenesis and therapeutic response, have not yet been elucidated. METHODS: We aimed to analyze these polymorphisms in 212 CML patients and 212 healthy controls by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) approach. RESULTS: The VEGFA+936C>T polymorphism did not differ significantly between the CML patients and controls. The frequency of CT genotype was higher in CML patients than in controls (25 vs. 18%), higher in males than in females (29 vs. 18%), was more prevalent in the patients with splenomegaly (p = 0.03), and was negatively associated with lactate dehydrogenase (LDH) levels (p = 0.01). The frequency of VEGFR2 mutant T-allele was higher in CML patients than controls (p < 0.0001). In the dominant model, patients having the combined AT and TT genotypes were associated with 2.6-fold higher risk of CML [odds ratio (OR) = 2.6, 95% confidence interval (CI) = 1.713.97, p < 0.0001]. VEGFR2 AT genotype was significantly associated with high blast count (p = 0.006), minor hematological response (p = 0.03) and poor cytogenetic response (p = 0.003), indicating its role in therapeutic resistance. In contrast, poor molecular response was observed in patients with TT genotype (p = 0.02). VEGFA+936C>T polymorphism was found to have synergistic interaction with VEGFR2+1416A>T in inflating the risk for CML further (P(interaction) = 0.0002). CONCLUSION: Our results indicate that VEGFR2+1416A>T polymorphism may be a useful marker in assessing the disease progression in CML patients. In addition, VEGFA+936C>T was observed to have additive effect in inflating the risk further.

BACKGROUND: The human ADIPOQ gene encodes adiponectin protein hormone, which is involved in regulating glucose levels as well as fatty acid breakdown. It is exclusively produced by adipose tissue and abundantly present in the circulation, with concentration of around 0.01% of total serum proteins, with important effect on metabolism. METHODS: Most deleterious nonsynonymous single nucleotide polymorphisms in the coding region of the ADIPOQ gene were investigated using SNP databases, and detected nonsynonymous variants were analyzed in silico from the standpoint of relevant protein function and stability by using SIFT, PolyPhen-2, PROVEAN and MUpro, I-Mutant2.0 tools, respectively. RESULT: A total of 58 nonsynonymous SNPs consisting of 55 missense variations, 3 nonsense variations were found in the ADIPOQ gene. Next, 14 of the 55 missense variants were predicted to be damaging or deleterious by three different software programs (PolyPhen-2, SIFT, and PROVEAN), and 38 of them were predicted to be less stable (I-Mutant 2.0 and MUpro software). Totally, 10 variants out of 55 missense variants were predicted to be both deleterious and reduce protein stability. Additionally, 3 nonsense variants were predicted to produce a truncated ADIPOQ protein. RMSD and total energy were calculated for 4 nsSNPs out of 10 nsSNPs which were both deleterious and showed a decrease in protein stability. CONCLUSION: rs144526209 has high root-mean-square deviation (RMSD) and lower total energy value compared to the native modeled structure. It was concluded that this nsSNP, potentially functional and polymorphic in the ADIPOQ gene, might be associated with diabetes, obesity, and inflammation.

BACKGROUND: In-stent restenosis is the most important limitation of modern coronary angioplasty. Drug-eluting stents solve this problem but at the cost of late stent thrombosis and longer duration of dual-antiplatelet therapy. Drug-eluting balloon (DEB) technology is now available and offers an attractive option for treatment of restenosis. METHODS: A cohort of 20 patients with in-stent restenosis after stenting were treated with a drug-eluting balloon and were followed up clinically and angiographically for 6 months. RESULTS AND CONCLUSION: Procedural success was achieved in all patients. 6 month clinical follow-up was available for all and 6 month angiographic follow up for 17 patients. On 6 month follow-up, 5 of the 20 patients had recurrence of angina and 4 patients had angiographic restenosis (2 focal, 2 diffuse). The mean Canadian Cardiovascular Society angina score improved significantly from 3.1 to 1.1. DEB offers a novel method of treatment for patients with in-stent restenosis with a good safety and efficacy profile.
RESUMO
OBJECTIVES: Cardioprotective activity of alcoholic extract of Saraca indica (SI) bark was investigated against cyclophosphamide induced cardiotoxicity. MATERIALS AND METHODS: Cardiotoxicity was induced in Wistar rats by administering cyclophosphamide (200 mg/kg, i.p.) single injection on first day of experimental period. Saraca indica (200 and 400 mg/kg, p.o.) was administered immediately after administration of cyclophosphamide on first day and daily for 10 days. The general observations and mortality were measured. RESULTS: Cyclophosphamide administration significantly (p < 0.05) increased lipid peroxidation (LPO) and decreased the levels of antioxidant markers such as reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). Cyclophosphamide elevated the levels of biomarker enzymes like creatine kinase (CK), creatine kinase isoenzyme MB (CK-MB), lactate dehydrogenase (LDH), aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP). Further, the cyclophosphamide treated rats showed changes in electrocardiogram (ECG) along with increased levels of cholesterol and triglycerides. Treatment with Saraca indica significantly (p < 0.05) reversed the status of cardiac biomarkers, ECG, oxidative enzymes and lipid profile in cyclophosphamide induced cardiotoxicity. Potential cardioprotective effect of Saraca indica was supported by histopathological examination that reduced severity of cellular damage of the myocardium. CONCLUSION: The biochemical, ECG and histopathology reports support the cardioprotective effect of Saraca indica which could be attributed to antioxidant activity.

This study was designed to evaluate the neuroprotective activity of ethanol extract of Pongamia pinnata stem bark in monosodium glutamate-induced neurotoxicity in rats. Neurotoxicity was induced by intraperitoneal injection of monosodium glutamate 2 g per kg body weight daily for 7 days. Ethanol extract of Pongamia pinnata stem bark (200 and 400 mg/kg) was administered orally after 1 h of monosodium glutamate treatment. Dextromethorphan (30 mg/kg, p.o.) was used as standard drug for the comparison. The degree of protection was determined by various behavioural, locomotor, muscle grip activity, lipid peroxidation and measurement of antioxidant status of glutathione, catalase and superoxide dismutase. Estimation of calcium, sodium and potassium ions in brain tissue and gamma aminobutyric acid level in serum was carried out. The histopathological study of brain tissue was also carried out. Treatment with Pongamia pinnata significantly improved monosodium glutamate-induced alteration in behavioural and locomotor activity and muscle strength. Significant decrease in lipid peroxidation and increase in glutathione, superoxide dismutase and catalase was observed in Pongamia pinnata treated group. Further, Pongamia pinnata also significantly reduced the monosodium glutamate-induced excitotoxicity by decreasing the level of Ca(+2) and Na(+) with concomitant increase in the level of K(+). Serum gamma aminobutyric acid level was also increased in Pongamia pinnata treated animals. Further, the histopathological evidence supports the neuroprotective activity of Pongamia pinnata. In conclusion, the present study suggests that the ethanol extract of stem bark of Pongamia pinnata possesses significant neuroprotective activity in albino rats.
RESUMO
The study was designed to investigate the hepatoprotective activity of methanol extract of Cissus quadrangularis against rifampicin-induced hepatotoxicity in rats.The coarse powder of the shade dried stem of Cissus quadrangularis was subjected to successive extraction in a Soxhlet apparatus using solvents petroleum ether (60-80°) and methanol. Liver damage was induced in Wistar rats by administering rifampicin (54 mg/kg, p.o.) once daily for 30 days. Methanol extract of Cissus quadrangularis (500 mg/kg, p.o) was administered 1 h prior to the administration of rifampicin (54 mg/kg, p.o.) once daily for 30 days. Silymarin (50 mg/kg p.o) used as reference drug. Elevated levels of aspartate transaminase, alanine transaminase, alkaline posphatase and bilirubin following rifampicin induction were significantly lowered due to pretreatment with methanol extract of Cissus quadrangularis. Rifampicin administration significantly increased lipid peroxidation and decreased antioxidant activities like reduced glutathione, superoxide dismutas and catalase. Pretreatment of rats with methanol extract of Cissus quadrangularis significantly decreased lipid peroxidation and increased the antioxidant activities. Histology of the liver section of the animals treated with the methanol extract of Cissus quadrangularis further confirms the hepatoprotective activity. The results of the present study indicated the hepatoprotective effect of methanol extract of Cissus quadrangularis which might be ascribable to its antioxidant property due to the presence of ß-carotene.
RESUMO
OBJECTIVE: To investigate the preventive and curative role of ascorbic acid on doxorubicin (dox)-induced myocardial toxicity in rats. MATERIALS AND METHODS: Animals were divided into five groups of six animals each. Group I served as normal control and received saline 5 ml/kg/day intraperitoneal (i.p.) for a period of 15 days. Group II animals received ascorbic acid 20 mg/kg per oral (p.o.) for 15 days as a pretreatment control (PR). Group III animals received dox 2.5 mg/kg body weight (b.w.), i.p., in six equal injections for two weeks for a total cumulative dose of 15 mg/kg b.w. Group IV animals received ascorbic acid 20 mg/kg p.o. for 15 days as a pretreatment followed by dox 2.5 mg/kg b.w., i.p., in six equal injections for two weeks for a total cumulative dose of 15 mg/kg body weight. Group V animals received dox 2.5 mg/kg b.w., i.p., in six equal injections for two weeks for a total cumulative dose of 15 mg/kg b.w. followed by ascorbic acid 20 mg/kg p.o for 15 days as post-treatment control (CR). The biochemical parameters such as tissue glutathione (GSH), malondialdehyde (MDA), catalase (CAT), and superoxide dismutase (SOD), and enzyme biomarkers such as creatine phosphokinase (CPK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were monitored. RESULTS: Pretreatment with ascorbic acid (20 mg/kg p.o.) significantly protected the myocardium from the toxic effect of dox (PR), by increasing the levels of antioxidant enzymes such as GSH, SOD, and CAT toward normal and decreased the levels of MDA, CPK, LDH, AST, and ALT as compared with dox-treated rats. Post-treatment with ascorbic acid to dox-treated group (CR) significantly increased the levels of tissue GSH, SOD, CAT and significantly decreased the level of MDA as compared with dox-treated group. It also reduced the severity of cellular damage of the myocardium as confirmed by histopathology. The restoration of the endogenous antioxidant system clearly depicts that ascorbic acid produced its protective effect by scavenging the reactive oxygen species. CONCLUSION: The results obtained in this study provide evidence for the usefulness of the ascorbic acid as a cardioprotective agent.
RESUMO
OBJECTIVE: The present investigation was undertaken to explore the possible mechanisms of Plectranthus amboinicus leaf extract in alloxan-induced diabetic rats. MATERIALS AND METHODS: Control and alloxan-induced diabetic albino rats received different treatments; orally control (vehicle), 200 mg/kg and 400 mg/kg of ethanol extract of Plectranthus amboinicus (PAEE) and 600 µg/kg of glibenclamide (standard) for 15 days. At the end of the experiment, the animals were sacrificed and enzyme activities of carbohydrate metabolism were measured in the liver. RESULTS: Diabetic control rats showed a significant elevation (P < 0.001) in fasting blood glucose on successive days of the experiment as compared with their basal values, which was maintained over a period of 2 weeks. Daily oral treatment with PAEE showed a significant reduction (P < 0.001) in the blood glucose levels on successive days of the experiment as compared with their basal values. The most pronounced antihyperglycemic effect was obtained with the dose of 400 mg/kg. PAEE shows a dose-dependent reduction in gluconeogenic enzymes like glucose-6-phosphatase and fructose-1,6-disphosphatase. After 15 days of treatment with PAEE, glycolytic enzymes like phosphoglucoisomerase resulted in a significant increase with a concomitant significant decrease in the activities of aldolase. On the other hand, glucose-6-phosphate dehydrogenase was significantly improved in diabetic rats on administration of PAEE; the 400 mg/kg dose of PAEE elicited a more potent effect compared with the 200 mg/kg dose. CONCLUSION: The results obtained in this study provide evidence of the antidiabetic activity of PAEE, mediated through the regulation of carbohydrate metabolic enzyme activities.
RESUMO
OBJECTIVES: To investigate the effect of the aqueous extract of Phyllanthus niruri (Aq.E.PN) against doxorubicin (Dox)-induced myocardial toxicity in rats. MATERIALS AND METHODS: Cardiotoxicity was produced by Dox administration (15 mg/kg for 2 weeks). Aq.E PN (200 mg/kg, orally) was administered as pretreatment for 2 weeks alternated with Dox for the next 2 weeks. The general observations, mortality, histopathology, biomarker enzymes like lactate dehydrogenase (LDH), creatinine phosphokinase (CPK) and alkaline phosphatase, diagnostic enzyme markers like aspartate aminotransferase (AST) and alanine aminotransferase (ALT), and antioxidants such as glutathione (GSH), superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA) were monitored after 3 weeks of the last dose. RESULTS: Pretreatment with the Aq.E.PN significantly (P < 0.01) protected the myocardium from the toxic effects of Dox by reducing the elevated level of biomarker and diagnostic enzymes like LDH, CPK, AST and ALT to the normal levels. Aq.E PN increased the GSH, SOD and CAT levels and decreased the MDA levels in cardiac tissue. Administration of Dox caused cardiomyopathy associated with an antioxidant deficiency. CONCLUSION: These results suggest a cardioprotective effect of P. niruri due to its antioxidant properties.
RESUMO
The present study was designed to compare the curative role of proton pump inhibitors, omeprazole, rabeprazole and lansoprazole against dexamethasone-induced ulcer model. Dexamethasone (5 mg/kg/day) was used as an ulcerogen. Dexamethasone suspended in 1% CMC in water was given orally to all rats. Omeprazole (20 mg/kg), rabeprazole (20 mg/kg), and lansoprazole (20 mg/kg) were administered by oral route 30 minutes prior to dexamethasone for ulcer protective studies, gastric secretion and mucosal studies. Effects of proton pump inhibitors were determined by the evaluation of various biochemical parameters such as estimation of myeloperoxidase, cortisol, alkaline phosphatase, malondialdehyde, endogenous anti-oxidants like superoxide dismutase, catalase and reduced glutathione. In dexamethasone induced ulcer model, omeprazole showed significant decrease in malondialdehyde, myeloperoxidase, alkaline phosphatase level and increase in superoxide dismutase, catalase and reduced glutathione level as compared to rabeprazole and lansoprazole. Omeprazole showed significant reduction in cortisol content where as rabeprazole and lansoprazole did not show significant changes as compared to control. The result indicates that omeprazole is the most effective and selective proton pump inhibitor in dexamethasone induced ulcer model as compared to rabeprazole and lansoprazole.
RESUMO
OBJECTIVE: The study was designed to investigate the hepatoprotective activity of methanol extract of Cissus quadrangularis (CQ) against isoniazid-induced hepatotoxicity in rats. MATERIALS AND METHODS: The successive petroleum ether (60-80°C) and methanol extracts of C. quadrangularis were used. Hepatic damage was induced in Wistar rats by administering isoniazid (54 mg/kg, p.o.) once daily for 30 days. Simultaneously, CQ (500 mg/kg p.o) was administered 1 h prior to the administration of isoniazid (54 mg/kg, p.o.) once daily for 30 days. Silymarin (50 mg/kg p.o) was used as a reference drug. RESULTS: Elevated levels of aspartate transaminase, alanine transaminase, alkaline posphatase, and bilirubin following isoniazid administration were significantly lowered due to pretreatment with CQ. Isoniazid administration significantly increased lipid peroxidation (LPO) and decreased antioxidant activities such as reduced glutathione, superoxide dismutase, and catalase. Pretreatment of rats with CQ significantly decreased LPO and increased the antioxidant activities. CONCLUSION: The results of this study indicated that the hepatoprotective effect of CQ might be attributed to its antioxidant property.
RESUMO
In the present study, 70% ethanol extract of Mimusops elengi Linn. bark was assessed for antiinflammatory, analgesic and antipyretic activities in animals. The antiinflammatory activity of ethanol extract of Mimusops elengi (200 mg/kg, p.o) was evaluated using carrageenan-induced paw edema and cotton pellet-induced granuloma models. Analgesic effect was evaluated using acetic acid-induced writhing and Eddy's hot plate models and antipyretic activity was assessed by Brewer's yeast-induced pyrexia in rats. The ethanol extract of Mimusops elengi (200 mg/kg, p.o) significantly inhibited the carrageenan-induced paw oedema at 3rd and 4th h and in cotton pellet model it reduced the transudative weight and little extent of granuloma weight. In analgesic models the ethanol extract of Mimusops elengi decreases the acetic acid-induced writhing and it also reduces the rectal temperature in Brewer's yeast induced pyrexia. However, Mimusops elengi did not increase the latency time in the hot plate test. These results show that ethanol extract of Mimusops elengi has an antiinflammatory, analgesic and antipyretic activity.
