The status of the Arbuscular Mycorrhizal (AM) fungi associated with the ischolar_mains of ten different medicinal plants viz., Aristolochia bracteata, Centella asiatica, Cichorium intybus, Eclipta prostrata, Hygrophylla auriculata, Indoneesiella echioides, Ocimum sanctum, Oxalis corniculata, Phyla nodiflora and Solanum trilobatum belonging to eight families such as Apiaceae, Aristolochiaceae, Solanaceae, Verbenaceae, Oxalidaceae, Labiatae, Acanthaceae and Asteraceae growing in the State Forest Department's medicinal garden at Aliyar, Tamil Nadu was investigated. The study revealed that all the plant species had AM colonization in the ischolar_mains and spore population in the rhizosphere soils. But there is a variation in per cent colonization in the ischolar_mains and soil spore population in different plant species. Among different plants studied, maximum percent ischolar_main colonization and soil spore population of AM fungi were observed in the plant samples of Ocimum sanctum and Centella asiatica. Low per cent colonization and soil spore population was observed in the plant samples of Cichorium intybus. Among different AM fungi isolated and identified, the most dominant was Glomus which had ten different species found in the rhizosphere of different medicinal plants studied.

Six new random copolyesters with ethereal linkages were prepared from a potential mesogenic non-linear monomer 4, 4'-oxybis(benzoic acid) by direct poly-condensation with different aliphatic and aromatic diols in pyridine solution. Diphenylchlorophosphate (DPCP) was employed as the condensation agent. Viscosity measurements, FTIR, 1H and 13C NMR spectral data were used for investigating their structural features. The thermal phase transition behavior of these polymers was investigated by Differential Scanning Calorimetry (DSC). Agar well diffusion method was employed to study the antibacterial activity of these random copolyesters. All the six random copolyesters showed significant inhibition against the test bacteria. The presence of ether group in the main chain of the polyester enhances the solubility in organic solvents and hence eases processing.Keywords

Objectives: This study involves the measurement of obstructions in the blood flow of an arterial system. An attempt is made to find the correlation between the pressure and flow of the blood. Methods: The obstructed area produces vascular sounds which are acquired through disturbed blood flow patterns. The measurements are carried over by audio frequency analysis of the sound observed during arterial stenosis. These sounds can be measured using piezoelectric film sensor by placing it in the wrist and mid arm in the blood flow path. Results:The sounds that initiate in the narrowed arteries is measured by non-invasive, sensitive piezoelectric film sensor that captures the vibration caused by the flow of blood inside arteries and generate appropriate waveform for different flow conditions. Conclusion: The waveforms are analyzed in spectrum analyzer and compared with the normal flow patterns and if the values deviate from normal it is concluded for occlusion or clot that happened in the blood flow passage.Keywords
