ANTIBACTERIAL ACTIVITY OF SELECTED MEDICINAL PLANT IN TRADITIONAL TREATMENT OF WOUND INFECTION IN SOUTHEAST INDIA

Objective: The wound healing potential of fruit peel of Pithecellobium dulce Benth, a plant traditionally used for wound treatment against wound- infecting bacteria, was assessed using disc diffusion and microtitre plate methods. Methods: P. dulce fruit peel was extracted using ethyl acetate, methanol and water and tested for their antimicrobial activities against bacterial isolates from wound infection using disc diffusion and microtitre plate methods. Results: All the three extracts had antimicrobial activities, among which methanol extract had higher activities against all the tested organisms compared to the ethyl acetate and aqueous extracts. The most susceptible organism to all the extracts was K. pneumonia and S. aureus while the most resistant were P. mirabilis and P. vulgaris. Conclusion: The potential antibacterial activity of P. dulce plant against both gram-positive and gram-negative bacteria justifies the use of the plant as the wound healing agent. The isolation of active principle of this plant may serve as source and lead for the synthesis of drugs in pharmaceutical industries

Wireless Dual DC Motor Control

Abstract—“WIRELESS DUAL DC MOTOR CONTROL ” is less complex than the standard dc motor control. The device aim is how to build dual dc motor control system, combined with a wireless receiver and transmitter which will tell the two independent motors at which speed they should move and in what direction. There are four core components: input system for the transmitter, a wireless transmitter, wireless receiver and a motor controller connected to the receiver. Transmission and reception are enabled using XBee module. The information is sent to the motor through an XBee transmitter via system software ‘Terminal’. XBee receiver placed on the robot will automatically connect with the transmitter and begin receiving data. The receiver will receive the unique values from an XBee module and tells each motor independently which way to turn and how fast to move. Software is loaded into the PIC. Motor control combined with wireless transmitter and receiver is an uncomplicated and low cost design that works reliably

Anti-Diabetic Activity Of Aqueous Extract Of Pithecellobium Dulce Benth Fruit Peel On Streptozotocin Induced Diabetic Rats

The decoction of the Pithecellobium dulce fruit peel has been used for the control of diabetes mellitus in the traditional method adopted by the local people of northwest region of Tamil Nadu, India. The present study was carried out to investigate the anti-diabetic potential of aqueous extract of Pithecellobium dulce fruit peel by its oral administration (200 mg/kg) to streptozotocin-induced diabetic rats. The levels of blood glucose, urine sugar, glycosylated hemoglobin, glucose-6-phosphatase, fructose-1,6-bisphosphatase, total cholesterol, triglycerides, aspartate transaminase, alanine transaminase, alkaline phosphatase and reduced  glutathione were increased significantly whereas the levels of plasma insulin, hexokinase, protein, liver glycogen, reduced glutathione, superoxide dismutase, catalase and glutathione peroxidase were decreased in streptozotocin-induced diabetic rats and it was normalized after treatment of aqueous extract. Glibenclamide was used as the standard drug. These outcomes suggest that the aqueous extract possesses anti-diabetic activity and supports the traditional use of the Pithecellobium dulce fruit peel decoction as hypoglycemic agent

Analytical Method Development and Validation of Iron, Arsenic, Cadmium, Mercury and Lead Content in Sunset Yellow by Inductively Coupled Plasma Mass Spectrometry (Icp-Ms)

A method for determining the iron, arsenic, cadmium, mercury, and lead content in Sunset Yellow by ICP-MS was developed, verified, and implemented for routine ICP-MS analysis. Inductively coupled plasma mass spectrometry (ICP-MS) is a good instrument for determining the basic composition of numerous substances. Iron, arsenic, cadmium, mercury, and lead metal as defined in USP (233) linearity, method precision, accuracy, robustness, and ruggedness factors were taken into account and analysed for method validation in this work. The recovery rates of iron, arsenic, cadmium, mercury, and lead metals ranged between 92.0% and 101.4%. The detection limits of all elements investigated demonstrated the procedure's suitability for routine analyses. To summarize, the provided analytical processes can be used to measure the mass fractions of iron, arsenic, cadmium, mercury, and lead components in Sunset Yellow samples

NLO-QCD corrections to e+ e- --> hadrons in models of TeV-scale gravity

We present results on NLO-QCD corrections to the process e+ e- --> hadrons via photon-, Z- and graviton-exchange in the context of TeV-scale gravity models. The quantitative impact of these QCD corrections for searches of extra dimensions at a Linear Collider is briefly discussed.Comment: 10 pages, LaTeX, using axodraw.st

To study the association of antiphospholipid syndrome in patients with bad obstetric history

Background: Antiphospholipid syndrome is an autoimmune condition characterized by vascular thrombosis and /or pregnancy morbidity in the presence of antiphospholipid antibodies. A failure or significant delay in recognizing APS as the underlying disease entity may leave to the loss of an opportunity to prevent serious consequences of the disease and the associated pregnancy complications. Aim of the study was to study the association of Antiphospholipid Syndrome (APS) in patients with bad obstetric history (BOH).Methods: Patients registered in Obstetrics and Gynecology Department SAT Hospital, Medical College, Trivandrum, Kerala with bad obstetric history (BOH) meeting the inclusion and exclusion criteria were recruited for the study. They were followed up in the postnatal ward after abortion and preterm delivery as per protocol for bad obstetrics outcome evaluation. They were offered lab test in standard labs for APL Syndrome especially LAC and anti-cardiolipin antibodies IgM and IgG. Those tested positive were retested 12 weeks later also to confirm the test. Then the various adverse pregnancy outcomes were studied in both APLA positive and negative groups.Results: The association of APLA with bad obstetric history (BOH) in the present study are as follows- Late miscarriages-16%, miscarriages less than 10 weeks-12%, Preterm- 10.8%, unexplained death-14%, Severe Pre-eclampsia-12.3%, IUGR-11.8%, Abruption-11.1% of which late miscarriages more than10 weeks was the commonest association.Conclusions: The study shows that women with bad obstetric history (BOH) and those cases where miscarriage occurred after the appearance of foetal cardiac activity should be investigated for APLA in the preconceptional period itself in the next pregnancy earlier and if positive should be given prophylaxis for the same to prevent a miscarriage in future pregnancy
