Probiotic effects of lactic acid bacteria against Vibrio alginolyticus in Penaeus (Fenneropenaeus) indicus (H. Milne Edwards)

Cell free extracts of four strains of Lactic acid bacteria (LAB) viz. Lactobacillus. acidophilus, Streptococcus.cremoris, Lactobacillus bulgaricus –56 and Lactobacillus bulgaricus –57 inhibited growth of Vibrio alginolyticus in nutrient broth. The antagonism of LAB to Vibrio alginolyticus was further confirmed by streak plating wherein suppression of growth of Vibrio was obtained. Juveniles of Penaeus indicus (average weight 0.985 ± 0.1 g) on administering orally a moist feed base containing 5 × 106 cells·g of the four LAB probionts for a period of four weeks showed better survival (56 to 72%) when challenged with V. alginolyticus by intra-muscular injection of 0.1 ml containing 3 × 109 cells·ml. Animals maintained on a diet devoid of bacterial biomass exhibited 80% mortality

COMPARATIVE STUDY OF EFFECTS AND ADVERSE REACTIONS OF LEVOCETIRIZINE, RUPATADINE AND MOMETASONE IN PATIENTS OF ALLERGIC RHINITIS

Aim: To compare the therapeutic efficacy and safety of Rupatadine and mometasone with Levocetirizine which is most commonly used drug. To study the effects of levocetirizine, Rupatadine and mometasone on absolute eosinophil count and IgE levels. Methodology: The participants were randomly divided into 3 groups of 25 patients each and treated as follows: Group I: were treated with Levocetirizine 5mg OD for 14 days, Group II: were treated with Rupatadine 10mg OD for 14 days, Group III: were treated with Mometasone two sprays (50mcg of mometasone in each spray) in each nostril once daily (total daily dose of 200mcg) for 14 days. The patients were asked to report at the hospital after 14 day and they were followed up with regard to clinical improvement of symptoms and signs and any adverse effects as reported by the patient. Rhinoscopy finding, X- ray of para nasal sinus, improvement in symptoms (sneezing, Itching, nasal discharge, nasal blockage and anosmia) Absolute eosinophils count, Serum IgE levels and adverse reports were studied and investigation were compared before and after treatment. Result: Rhinoscope finding showed treatment with mometasone became normal but X- Ray of para nasal sinus results showed levocetirzine showed higher rate of improvement. In improvement of symptoms sneezing, itching and nasal discharge was high mometasone. In all groups post treatment there was no changes in Ig E and Absolute Eosinophils count. ADR reported with mometaxone. Conclusion: The three drugs, levocetirizine, rupatadine and mometasone were found to have similar levels of efficacy in controlling the symptoms of the allergic rhinitis. The physical signs improved better with mometasone than the other 2 drugs. The 3 drugs levocetirizine, rupatadine and mometasone had no significant effect on the absolute eosinophil count and the serum IgE levels. Adverse effects were found to be more with levocetirizine than the other two drugs. Considering this factor and also the fact that long term use of corticosteroids like mometasone is undesirable, rupatadine appears to be a better choice in the treatment of allergic rhinitis

Mechanisms for Introduction of Pseudo Ductility in Fiber Reinforced Polymer Composites- A Review

Advanced polymer matrix composites are gaining the market in their way due to their exceptional specific stiffness, specific strength, fatigue, and corrosion resistance in the field of Auto-Tech, Aero-Tech, Biotech, etc. However, the lack of ductility and catastrophic failure has limited their application in these areas. Hence there is a need to explore means and protocols for designing the reduced factor of safety with high-performance toughened composites. To address this problem, a new generation of high-performance composites with pseudo-ductile or ductile behavior is needed. The ongoing High-Performance Ductile Composite Technology (HiPerDuCT) program jointly between the University of Bristol U.K and Imperial College London to address this challenge by developing newer materials. The fiber architectures made under this project gave a more gradual failure rather than catastrophic failure which improves the mechanical properties. This paper mainly focuses on addressing this evolution of pseudo ductility in fiber-reinforced composites. In addition to this, an attempt has been made to newer possible fiber positions in matrix materials for inducing reasonable ductility in composites

On the Difficulty of Manhattan Channel Routing

We show that channel routing in the Manhattan model remains difficult even when all nets are single-sided. Given a set of n single-sided nets, we consider the problem of determining the minimum number of tracks required to obtain a dogleg-free routing. In addition to showing that the decision version of the problem isNP-complete, we show that there are problems requiring at least d+Omega(sqrt(n)) tracks, where d is the density. This existential lower bound does not follow from any of the known lower bounds in the literature

Correlations due to localization in quantum eigenfunctions of disordered microwave cavities

Non-universal correlations due to localization are observed in statistical properties of experimental eigenfunctions of quantum chaotic and disordered microwave cavities. Varying energy {E} and mean free path {l} enable us to experimentally tune from localized to delocalized states. Large level-to-level Inverse Participation Ratio (IPR I_{2}) fluctuations are observed for the disordered billiards, whose distribution is strongly asymmetric about . The density auto-correlations of eigenfunctions are shown to decay exponentially and the decay lengths are experimentally determined. All the results are quantitatively consistent with calculations based upon nonlinear sigma-models.Comment: 4 pages, LaTex, 5 .jpg figures.

ANTI INFLAMMATORY EFFECT OF CIPROFLOXACIN, AZITHROMYCIN AND DICLOFENAC SODIUM ON CARRAGEENAN INDUCED HIND PAW EDEMA IN MICE

Background: Obviously, antibacterial agents are primarily directed against bacteria. However, because microorganisms can initiate an exaggerated inflammatory reaction, and as pathogens which persist in cryptic reservoirs (cells or granuloma tissue) can be the underlying cause of chronic inflammation, the hypothesis that antibacterials can down regulate inflammation. Methodology: Healthy adult mice weighing 20 - 30 g and aged 6-8 weeks, each group 6 mice were included. 1% carrageenan administered to produce inflammation. Grouping: Group 1: Normal saline 0.2 ml. i.p., Group 2: Diclofenac sodium 25mg/kg, Group 3 Ciprofloxacin 50 mg/kg, Group 4: Azithromycin 20mg/kg. Drugs were administered Intra Peritoneal. After 30 min of test drugs administration each group of mice were received subplantar administration of 0.05ml of saline (Control) or 0.05ml carrageenan (1%) for test groups 2 to 4. Paw volumes were measured by dipping in to the mercury plethysmograph at 30, 60, 120 and 180 minutes and results were tabulated. Results: Diclofenac, ciproflaoxin, Azithromycin inhibited paw edema in % at 30min 42.85, 28.55, 14.28, at 60min 75, 50, 25, at 120min 71.42, 42.85, 14.28, and at 180 min 50, 50, 25 respectively. Conclusion: Ciprofloxacin (50mg/kg) has exhibited consistent anti-inflammatory, but the anti-inflammatory activity of is less than that of Diclofenac sodium and Azithromycin also has exhibited anti-inflammatory activity, though much less when compared to Diclofenac sodium and Ciprofloxacin.
