Introduction: Epidural anesthesia is the most commonly used technique for providing not only peri-operative surgical anesthesia but post-operative analgesia in lower abdominal and limb surgeries. Our study aimed to assess the comparison between ropivacaine(Group A) and combination of ropivacaine with fentanyl (Group B) in terms of their analgesic effect, hemodynamic stability, side effects and requirement of rescue drug in post operative patient of total knee replacement surgery. Materials and methods: After surgery, Pulse rate, systolic and diastolic blood pressure, Sp02, visual analogue score and requirement of other analgesics was studied at every 30 minutes for 2 hrs, then hourly up to 12 hrs and every 2 hourly thereafter up to 24 hrs in group A and Group B. Patients were also observed for side effects. Statistically significant when the p <0.05 and highly significant if p<0.001. Results: In our study, there was no significant difference amongst the groups in respect to age, sex distribution, height and ASA physical status. There was no statistically significant difference in pulse rate, blood...

Medicinal Plants are endowed with phytochemicals that are vital to counter various metabolic disorders like Oxidative damage in cells causing various degenerative diseases. Hence, the present study deals with the assessment of antioxidant activity and phytochemical screening of the aqueous extract of Jasminum officinale leaves. Antioxidant potential was evaluated in vitro using free radical scavenging assays for DPPH, NO, superoxide and ABTS radicals in addition to Reducing Power assessment. The total phenolic, flavonoid and flavonol contents of the extract were also assessed using standard procedures. The phytochemical analysis of the extract revealed the presence of tannins, flavonoids, terpenoids, alkaloids, steroids and its glycosides in addition to saponins and coumarins. A positive correlation between the inhibition of free radicals and concentration of the extract suggests significant antioxidant potential of the extract. The IC50 values for DPPH, NO, superoxide and ABTS radicals were 41.16, 30.29, 20.19, and 29.48 µg/ml respectively as compared to the standard, ascorbic acid, having 42.79, 36.74, 38.22, and 45.57 µg/ml, for the same radicals. It is interesting...

Objective: To develop and validate a novel and easy first order derivative spectroscopic method for the simultaneous determination of multicomponent dosage form which contains Methylcobalmine, Alpha lipoic acid and Pregabaline. Method: Measurement was achieved by selecting different Zero crossing points i.e ZCP for Methylcobalamine and Alpha lipoic acid at 436.24 nm, ZCP for Alpha lipoic acid and Pregabalin at 338.0 nm and ZCP for Pregabalin and Methylcobalmin at 307.03 nm. The method was validated according to ICH guideline. The proposed method was applied for quantification of all three drugs in the marketed formulations. Results: The method was found linear in the range of 100-140µg/ml for Pregabalin,1-1.4µg/ml for Methylcobalmine and 130-170µg/ml for Alpha lipoic acid respectively. The co-efficient co-relation was found to be 99.5 % for Pregabalin, 99.56 for Methylcobalmine and 99.61 for Alpha lipoic acid. The accuracy and precision were within acceptable limits. Conclusion: The method is simple, accurate, precise, rapid and cheap. The proposed method can be used for analysis of multicomponent marketed...

The living organisms of the aquatic ecosystem have been directly affected by the accumulation of the heavy metals in the aquatic environment 1. Fishes are very good biosensors of aquatic contaminants and as bio-indicator species respond with great sensitivity to changes in the aquatic environment. Copper will accumulate in many different organs in fish and mollusks. In the present study the acute toxicity of copper sulphate was analyzed by the exposure of the copper sulphate to the fresh water fish Grass carp (ctenopharyngodon idella) in the concentration of (3ppm/l for 15 days). The vital organs like Gill, Liver, and muscle tissues showed pronounced effect on the activity of enzymes. Copper sulphate administration decreases the activity of the antioxidants SOD (superoxide dismutase), and CAT (catalase), and the activity of the enzymes GPx (Glutathione peroxidase), GR (Glutathione reductase), GSH (Reduced Glutathione) to the significant level in all the tissues. The level of Lipid peroxidation (LPO) was increased in all the tissues compared to the control group. The decreased activity of antioxidants...

A series of discrete mononuclear lanthanide(III) complexes of H2L1 [Ln(H2L1)(NO3)2]NO3.nH2O (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Y; n = 1 for Ce; n = 2 for La, Sm, Gd and Y; n = 3 for Pr, Nd, Eu, and Tb) have been prepared by the condensation of Schiff-bases with the precursor compounds namely, 2,6-diformyl-4-methylphenol, 1,5-diamino-3-azamethypentane and 4,5-dimethyl-1,2-phenylenediamine. All the mononuclear complexes have been prepared in situ by the step-wise condensation from the precursor compounds. The phenolate oxygen atom of the nucleating ligand behaves as a bridging group between the metal. The complexes have been characterized by elemental analysis, IR, UV-Visible, ESI mass spectra and magnetic studies. The yield of these complexes increases from lighter lanthanides to heavier lanthanides. The fluorescence studies were carried out for europium and terbium complexes. The results of elemental analysis of the complexes are in good agreement with the theoretical values. The complexes are soluble in methanol, chloroform, DMF, DMSO, and CH3CN. Conductivity studies reveal that all the complexes are 1:1...
