Evaluation of anthelmintic antimicrobial and antioxidant activity of Chenopodium album.

The objective of this study was to evaluate the anthelmintic, antimicrobial and antioxidant activities of Chenopodium album against gastrointestinal nematodes of sheep and some pathogenic microbes. A worm motility inhibition assay was used for in vitro study, and a faecal egg count reduction assay was used for an in vivo study. Various concentrations ranging from 100 to 500 µg/ml of the extract were subjected to antimicrobial screening by disc diffusion method against four selected bacterial (Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas multocida and Escherichia coli) and two fungal (Aspergillus flavus and Candida albicans) strains in order to estimate the medicinal potential of the herb. DPPH (1,1-diphenyl-2-picrylhydrazyl), riboflavin photo-oxidation, deoxyribose, lipid peroxidation assays were used for antioxidant activity. The extracts exhibited dose- and time-dependent anthelmintic effects on the Haemonchus contortus as compared to levamisole. The extract showed maximum inhibitory effect against S. aureus (28 ± 0.14 mm), while as mild inhibitory effect was observed against E. coli among the selected microbial strains. The effect produced by the different extract concentrations was comparable with the standard antibacterial agent streptomycin sulphate and antifungal agent nystatin, which were used as effective positive control in the study. The antioxidant activity showed that the extracts exhibited scavenging effect in concentration-dependent manner on superoxide anion radicals and hydroxyl radicals leading to the conclusion that the plant has broad spectrum anthelmintic, antimicrobial and antioxidant activities and could be a potential alternative for treating various diseases.

Transradial versus transfemoral approach for coronary angiography and angioplasty - A prospective, randomized comparison.

BACKGROUND: PCI has been done traditionally through transfemoral route. But now transradial and transbrachial routes are also coming up in practice. We compared transradial versus transfemoral routes for ease of operability, time for procedure, complications, and failure rates through a prospective study. METHODS: Four hundred Patients admitted in department of cardiology for percutaneous interventions were enrolled in the study. 200 patients were assigned to each group randomly. A single team did all the procedures. Pre procedure, intra procedure and post procedure data of all the patients was collected, tabulated and analysed properly. RESULTS: Access time (6.0 ± 1vs 4.2 ± 0.7; P =0.001); Fluoroscopy time and overall procedure time (29 ± 11.3 Vs. 27.3 ± 12.4 min) were more with trans radial than transfemoral route, respectively. The most common post procedure complication, ecchymosis was seen in 20.5% in transfemoral group compared to 12.5% in transradial group (P 0.031). Thrombophelibites (17.5 VS 8%, P0.004); Hematoma (14.5 Vs 0%, P 0.005); post procedure access bleed (7 VS 3%, P 0.039) were seen in transfemoral than transradial group, respectively. Failure rates were almost similar. None of our patients had post procedure myocardial infarction, stroke, acute renal failure and infections. CONCLUSION: Transradial approach of PCI is better than transfemoral route with respect to complications like bleeding, haematoma formation, thrombophelebites and ecchymosis is concerned. However access and fluoroscopic time is more with the former. We recommend the transradial route for PCI. TRIAL REGISTRATION: Trial is retrospectively registered in ClinicalTrials.gov with the Identifier: NCT02983721 , Date of registration is December 2, 2016.

Association of Low Levels of Vitamin D with Chronic Stable Angina: A Prospective Case-Control Study.

BACKGROUND: Coronary artery disease (CAD) is a major cause of death and disability in developed countries. Chronic stable angina is the initial manifestation of CAD in approximately 50% of the patients. Recent evidence suggests that vitamin D is crucial for cardiovascular health. The prevalence of vitamin D deficiency in our region is 83%. A low level of vitamin D is associated with chronic stable angina. AIM: This study was aimed at supporting or refuting this hypothesis in our population. MATERIALS AND METHODS: The study was a prospective case-control study. We studied 100 cases of chronic stable angina and compared them with 100 matched controls. Vitamin D deficiency was defined as <20 ng/mL, vitamin D insufficiency as 20-30 ng/mL and normal vitamin D level as 31-150 ng/mL. RESULTS: The prevalence of vitamin D deficiency among cases and controls was 75% and 10%, respectively. 75% of the cases were vitamin D-deficient (<20 ng/mL); 12% were vitamin D-insufficient (20-30 ng/mL), and 13% had normal vitamin D levels (31-150 ng/mL). None had a toxic level of vitamin D. Among the controls, 10% were vitamin D-deficient, 33% were vitamin D-insufficient, and 57% had normal vitamin D levels. The mean vitamin level among cases and controls was 15.53 ng/mL and 40.95 ng/mL, respectively, with the difference being statistically significant (P ≤ 0.0001). There was no statistically significant relation between the disease severities, i.e., on coronary angiography (CAG) with vitamin D level. Among the cases, we found that an increasing age was inversely related to vitamin D levels (P = 0.027). CONCLUSION: Our study indicates a correlation between vitamin D deficiency and chronic stable angina. Low levels may be an independent, potentially modifiable cardiovascular risk factor.

White side test: A simple and rapid test for evaluation of nonspecific bacterial genital infections of repeat breeding cattle.

The objective of the present study was to determine the grades of nonspecific bacterial infection of genitalia of repeat breeding cattle by a simple and rapid test under field condition. For this purpose, a total of 100 crossbred Jersey cows comprising of 80 repeat breeding animals presented for treatment and 20 normal cyclic (control group) animals presented for artificial insemination at their first service were selected. Estrual cervical mucus from all the animals was collected at 8 to 12 hr after the onset of behavioral estrus and subjected to white side test (WST) and bacteriological examination. The results of WST showed only 15% of control group had infection but the remaining 85% were free of it. In contrast, the majority of repeat breeding animals (57/80) showed infection (71.25%) and only 28.75% animals were free of infection. In bacterial culture, 60 (75.00%) from the 80 repeat breeding animals were found positive, and 20 (25.00%) were free of bacteria. All the three samples of control group that showed no color reaction in WST had also no growth in bacterial culture. The WST results showed a positive (p < 0.01) correlation of 0.48 with bacterial culture. It is thus concluded that under field condition WST can be used as a prime modality for ascertaining nonspecific bacterial infection of repeat breeding cattle before subjecting them to any antibiotic therapy thereby reducing the cost of diagnosis and treatment.

Anthelmintic and antimicrobial activity of methanolic and aqueous extracts of Euphorbia helioscopia L.

The aim of this study was to evaluate the anthelmintic and antimicrobial efficacy of Euphorbia helioscopia crude extracts. A worm motility inhibition assay and egg hatch assay were used for in vitro study, and a faecal egg count reduction assay was used for in vivo study. The in vitro study revealed anthelmintic effects of crude methanolic extracts of E. helioscopia on live Haemonchus contortus worms as evident from their paralysis and/or death at 8 h after exposure. Different concentrations (12.5 mg ml(-1), 25 mg ml(-1) and 50 mg ml(-1)) of aqueous and methanolic extracts were used against H. contortus which exhibited dose-dependent anthelmintic effects on H. contortus. Different extracts of E. helioscopia on percent inhibitory egg hatching was very low as compared to levamisole. The antimicrobial activity of extracts ranging from 100 to 500 mg ml(-1) screened by disc diffusion method against four selected bacterial (Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas multocida and Escherichia coli) and two fungal strains (Aspergillus flavus and Candida albicans) was also dose dependent with the extract showing more inhibitory effects against S. aureus and E. coli and a minimum inhibitory effect against A. flavus. It is concluded that the entire plant of E. helioscopia possesses significant anthelmintic and antimicrobial activity and could be a potential alternative for treating cases of helminth infections in ruminants.

In vitro and in vivo anthelmintic activity of Euphorbia helioscopia L.

The anthelmintic potentials of the aqueous and methanol extracts of Euphorbia helioscopia were investigated. In folklore medicine, E. helioscopia (Euphorbiaceae) is used in the treatment of various gastrointestinal ailments and diseases. A worm motility inhibition (WMI) assay and egg hatch assay (EHA) were used for in vitro assessment, and a faecal egg count reduction (FECR) assay was used for an in vivo study. The in vitro study revealed anthelmintic effects of crude methanolic extracts of E. helioscopia on live Haemonchus contortus worms as evident from their paralysis and/or death at 8h after exposure, different concentrations (12.5 mg ml(-1), 25 mg ml(-1) and 50 mg ml(-1)) of aqueous and methanolic extracts were used against H. contortus which exhibited dose-dependent anthelmintic effects on H. contortus. Aqueous and methanolic extracts of aerial parts (stem, leaves and flowers) of E. helioscopia were found to have very low percent inhibitory egg hatching as compared to levamisole. It is concluded that the entire plant of E. helioscopia possesses significant anthelmintic activity and could be a potential alternative for treating cases of helminth infections in ruminants.
