Objectives: The present study was conducted to evaluate and compare the effect of vanadium pentoxide and chromium oxide in normal and streptozotocin induced diabetic albino rats. Methods: Diabetes was experimentally induced by injecting intraperitoneally with a single dose of 60mg/kg. The animals were considered as diabetic, if their blood glucose values were above 300 mg/dl on the 10th day after injection. The blood glucose estimation was done by glucose oxidase method. Glibenclamide was taken as standard drug. The one-way ANOVA followed by Dunnett’s ‘t’ test was used for statistical analysis. Results: The blood glucose levels were found to be significantly (p<0.05) decreased in vanadium pentoxide and chromium oxide treated groups. Conclusion: This study suggests that vanadium pentoxide and chromium oxide have antidiabetic effect in a dose dependent...

Sophisticated analytical methods like HPLC and Mass spectroscopic methods which being employed for analysis, are relatively expensive and hence there is a need for developing simple analytical methods. In the proposed work, such methods have been developed and applied for routine determination of ketorolac in pharmaceutical formulations and bulk dosage forms. These methods were based on the formation of colored species on binding of ferric chloride and Hydrochloric acid for method A and binding of drug and Folin Cioclataeu reagent in alkaline conditions for method B, and the colored chromogen obtained in each method was finally treated with the drug ketorolac to produce yellow colored for method A and blue colored chromogen for method B with λmax at 430 nm and 627 nm respectively. Statistical analysis of these methods exhibited Sandell’s Sensitivity of 0.8 and 0.0617 (Method A and B) respectively, and the relative standard deviation (RSD) of these methods were found equal to 0.69 and 1.90 respectively, indicating that these methods are highly reproducible, based on the principle...

The term HbA1c refers to glycated haemoglobin. By measuring glycated haemoglobin (HbA1c), clinicians are able to get an overall picture of what our average blood sugar levels have been over a period of weeks/months. Diabetic neuropathy is generally assessed in clinical practice by a combination of objective and subjective measures. Nerve conduction studies, the distal sural sensory nerves and the bilateral common peroneal and posterior tibial motor nerve was performed in lower limb in female patient of 20-years old suffering from type-I diabetes from past 10-yeras and had poor glycemic control (haemoglobin [HbA1c] 9.56%). Studies showed motor conduction studies (MNCV) and sensory conduction studies (SNCV) of the lower extremities, revealed borderline- prolonged distal latencies, evoked CMAPs of reduced amplitude of common peroneal, posterior tibial (right and left) with reduced conduction velocity was observed and however sural SNAP amplitude recordings in lower limb was normal. F response latencies were markedly prolonged in patient. Electro-diagnostic techniques play an important role in the prognosis of diabetic neuropathy because timely intervention reduces disability and...

Enzymes plays a major role in industries like textile, leather, sugar, paper, rubber, tea etc., Microbes plays important role in enzyme production due to their fast growth rate, easy to manipulate for getting highly stable enzymes through genetic engineering and requires shorter time for production and purification steps. In our present study, we concentrated on the enzymes used in textile industries. Recently, many novel enzymes that prove to be the efficient in the process of desizing, peroxide removal, bio polishing have been developed for textile industries. In commercial point of view, finding of new enzymes with high activity and desired properties that can be potentially used for those processes is a continuous process. Hence, we tried to isolate the cellulolytic bacteria from red soil and produced the enzyme cellulase using specific media. The isolated bacterial species was identified as Bacillus species by morphological and biochemical analysis. Further the cellulase activity was analyzed and the parameters like pH, temperature, substrate concentration, and incubation time were also...

An hitherto new unreported [16]-membered dioxadiazanapthaldehyde based macrocyclic ligand (L) 2,11-dioxa-23,30-diaza heptacyclo [30.4.0.0 4, 9.0 12, 21. 0 14, 19. 0 24, 29. 0 34, 39]-tetraconta-12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40-pentadecaene, has been synthesized by two different synthetic routes each involving two stages. 2-Hydroxy-1-Napthaldehyde in the presence of potassium carbonate was treated with α,α’-dibromo-o-xylene to yield the dial derivative(I). The dial derivative(I) was further made to undergo Schiff base condensation with 1,2-diaminobenzene to yield the bright yellow macrocycle (L) in good yield. In the second method the Schiff base condensed product Napthaloph was synthesized and allowed to undergo Williamson’s condensation with α,α’-dibromo-o-xylene to yield the ligand (L). The neutral sixteen membered tetradentate dioxadiaza ligand(L) readily complexes with Co(III), Ni(II) and Cu(II) perchlorate salts in 1:1 mole ratio to yield complexes of formulae [Co(L)X2]ClO4, [Ni(L)X2], [Cu(L)X]ClO4, (X = Cl–, Br– and NO3–). The complexes were also synthesized by the metal template method. The yield of the template procedure was found to...
