EVALUATION OF IN VIVO ANTIDIABETIC AND ANTIOXIDANT ACTIVITY OF ARTOCARPUS HIRSUTUS SEEDS IN STREPTOZOTOCIN-INDUCED DIABETIC RATS
ABSTRACTObjective: The objective of the study was to evaluate the antihyperglycemic activity and in vivo antioxidant effect of Artocarpus hirsutus seeds in bothnormal and diabetic rats.Methods: Male Wistar rats weighing about 180-250 g were divided into six groups, of six rats each. Diabetes was induced by giving streptozotocin(30-50 mg/kg) intraperitoneally. Rats, which showed blood glucose levels ≥250 mg/dl, were selected for the study. Metformin (50 mg/kg) was used as a standard oral hypoglycemic agent. Oral glucose tolerance test was performed in all groups of rats. In the estimation of in vivo antioxidant activity,the levels of liver enzymes superoxide dismutase (SOD), lipid peroxidation, and CAT (catalase) were measured using standard methods.Results: The ethyl acetate seed extract of A. hirsutus at different doses was selected and administered orally. The blood glucose levels were estimatedby the glucose oxidase method, and insulin levels were measured by chemiluminescence assay method. Antihyperglycemic activity of the test drugin diabetic rats showed a significant reduction in blood glucose levels (p<0.001) at 2, 4, 6, and 8 hrs, respectively, as compared to diabetic groups.The antioxidant enzymes SOD and CAT levels were significantly raised, whereas malondialdehyde-thiobarbituric acid residue substances levels havedecreased (p<0.001).Conclusion: The results suggested that A. hirsutus seed extract showed a potential antidiabetic activity and antioxidant effect justifying the use of thedrug for the treatment of diabetes mellitus and its associated oxidative damage.Keywords: Antidiabetic, Antioxidant, Artocarpus hirsutus, Streptozotocin
Comparative Assessment on Linearity Test based V2Ï€ and VÏ€/2 Voltage Variations of Closed Loop IFOG
Interferometric Fiber Optic Gyroscope (IFOG) has to operate in closed loop condition to achieve inertial grade performance. The closed loop system is mainly depends upon the amplitude of the ramp signal (V2Ï€ of IOC) and bias (square wave) signal frequency (fbias). The digital phase ramp function is given as feedback to the optical system and makes gyro to null condition. The peak-to-peak amplitude (VÏ€/2) of biasing signal is one-fourth of the ramp amplitude (V2Ï€). If there are any variations in the amplitude of the ramp and biasing signals, then it introduces variations in the gyro performance. In this paper, a comparative discussion made in the gyro parameters for three cases: (i) V2Ï€ (vary) & VÏ€/2 (constant), (ii) VÏ€/2 (vary) & V2Ï€ (constant) and (iii) both V2Ï€ and VÏ€/2 are varying simultaneously. The effects on gyroscope are described with the derived values in terms of linearity. From the experimental results, it was observed that the gyro output is very sensitive with respect to V2Ï€ variations and obtained the percentage error of 10% in gyro output, but very less effect due to VÏ€/2 variations. So, the proper resetting of ramp voltage (V2Ï€) is required to avoid nonlinearities and instabilities in gyro output

Simultaneous determination of ezetimibe and simvastatin in rat plasma by stable-isotope dilution LC-ESI–MS/MS and its application to a pharmacokinetic study
AbstractA simple, sensitive and specific liquid chromatography–tandem mass spectrometry method was developed for simultaneous quantification of ezetimibe and simvastatin in rat plasma. The deuterium isotopes: ezetimibe d4 and simvastatin d6 were used as internal standards for ezetimibe and simvastatin, respectively. MS/MS detection involved a switch of electron spray ionization mode from negative to positive at retention time 3.01min. Samples were extracted from plasma by liquid–liquid extraction using tertiary butyl methyl ether. Chromatographic separation was achieved with Agilent Eclipse XBD-C18 column using mobile phase that consisted of a mixture of ammonium acetate (pH4.5; 10mM)–acetonitrile (25:75 v/v). The method was linear and validated over the concentration range of 0.2–40.0ng/mL for simvastatin and 0.05–15.0ng/mL for ezetimibe. The transitions selected were m/z 408.3→271.1 and m/z 412.0→275.10 for ezetimibe and ezetimibe d4, and m/z 419.30→285.20 and m/z 425.40→199.20 for simvastatin and simvastatin d6. Intra- and inter-batch precisions for ezetimibe were 1.6–14.8% and 2.1–13.4%; and for simvastatin 0.94–9.56% and 0.79–12%, respectively. The proposed method was sensitive, selective, precise and accurate for the quantification of ezetimibe and simvastatin simultaneously in rat plasma. The method was successfully applied to a pharmacokinetic study by oral co-administration of ezetimibe and simvastatin in SD rats
Adaptation and mitigation measures for climate change by the dry land farmers
ABSTRACT Due to climate change, there was significant impact on agriculture and allied areas and led to biotic and abiotic stresses. The study focused on the analyzing the awareness of the dryland farmers on the climate change and also the extent of adoption of adaptation and mitigation measures for climate change. Study was conducted in Chittoor district of Andhra Pradesh with 120 dryland farmers by following appropriate sampling procedure. Structured schedules were prepared for both awareness and adoption of measures for climate change. There was 84.47 percent of awareness on climate related changes followed by 74.27 percent on crop related changes, 73.61 percent on animal husbandry related changes and 61.11 percent on soil& water related changes. The item wise analysis indicates that delayed onset of monsoon, rainfall, temperature, availability of ground water, pests & diseases, drought conditions were the major areas in which farmers were well aware. Increased crop weed competition, reduced quality of produce, Increase in disease transmission, Decreased fertilizer use efficiency were the areas where farmers were not well aware. Intercropping was ranked first in extent of adoption followed by alteration in sowing/ planting dates, micro irrigation systems, use of drought tolerant varieties and use of pest and disease resistant varieties, etc. Very meager percent adoption was observed for crop rotation, high yielding and drought resistant forage crops/varieties, integrated weed management practices, use of suitable breeds/varieties. Strategy consisting of ten broad areas was designed for achieving climate resilient agriculture in dry land areas
Betel leaf yield in relation to soil fertility in Guntur district (Andhra Pradesh)
An attempt was made to survey betelvine gardens in Guntur district of Andhra Pradesh to ascertain soil fertility status and its impact on growth and yield of betelvine. All the soils were clay loam in texture. The pH of the soil was alkaline (7.1 to 8.4) and EC ranged from 0.35 to 1.61 dSm-1. The organic carbon (OC) content of the soil was in the range of 0.55 to 1.24%. The available nitrogen (N), phosphorus (P) and potassium (K) status ranged from 201 to 313, 10 to 60, 337 to 840 kg ha-1, respectively. Correlation indicated that the growth parameters viz., number of laterals, intermodal length, petiole length and soil parameter viz. pH, EC and P were positively correlated with betel leaf yield but relations were not significant, whereas, plant height and soil nutrients viz., OC content, N and K were significantly and positively correlated with leaf yield.
