To perform preliminary phytochemical screening, GC-MS analysis and to study the antimicrobial activity of Petroleum ether, ethanolic and aqueous extracts of Vernonia cinerea leaves. Leaves of Vernonia cinerea was shade dried, powdered and extracted with respective solvents. The extracts were then screened for phytocompounds, the petroleum ether and ethanol extracts were analysed by GC-MS to detect the compounds present in the polar and non polar solvent extracts of the leaves.

Auto exhaust pollution serve as the major driver of the deteriorating air quality in Rewa city. This study aims to investigate the effects of auto exhaust pollution on foliar morphological structure of road side ornamental shrub species, Bougainvillea spectabilis. Increased number of stomata and epidermal cells per unit area in leaf samples of Bougainvillea spectabilis collected from polluted sites than those from control sites is observed by light microscopic technique.

The Objective of the study is to determine the effect of Brahmi Nei with massage and varmam on dynamic gait index of children with spastic cerebral palsy. Among the 250 children 210 Spastic CP satisfied the inclusion criteria and were divided in to three groups (N=70 Nos). Group –I treated as an active control, Group –II received Brahmi Nei, Group - III received Brahmi Nei along with external therapies such as massage with Vasavu ennai and Varmam twice a day. Experimental period was 90 days and dynamic gait index was recorded 0th day and followed by every 30th day.

A new series of copper (II) and zinc (II) Schiff bases complexes containing the bidentate ligands N, N'-bis (diphenylmethylene) ethane-1, 2-diamine (L1) and N, N'-bis (diphenyl methylene) benzene-1, 2-diamine (L2) was prepared by the condensation of the ethylenediamine, or the orthophénylènediamine on benzophenone in ethanol at reflux. The Schiff base ligands and their corresponding complexes have been identified by IR spectroscopy, 1H NMR, 13C NMR and by ESI MS spectrometry.

Click synthesize of several novel tris-chalcone with 2,4,6-trichloro-1,3,5-triazine core from reaction of premade tris-aldhydes or tris-acetophenones with aromatic aldehydes or acetophenones under basic conditions in MeOH in the presence of NaOH are reported. All of the synthesized products were characterized by FT-IR, 1H, 13CNMR and elemental analysis. The antibacterial activities of tris-chalcones were estimated versus Staphylococcus aureus, Micrococcus luteus, Escherichia coli, Pseudomonas aeruginosa and Bacillus subtilis. Some compounds display promising activities.

The present study was carried out to investigate the phytochemical screening, antibacterial, antifungal activity and GC-MS analysis of Costus pictus leaf extracts. Antibacterial activity of Costus pictus leaf extracts was evaluated against Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Bacillus subtilis and Staphylococcus aureus and antifungal activity against Aspergillus niger, Aspergillus fumigatus, Aspergillus parasites, Candida albicans and M. Purpureus. Three different solvents Ethanol, Petroleum ether and Aqueous were used for extraction.

Aphis spiraecola Patch is a polyphagous aphid and is a major pest of citrus apple and Mexican aster. The diversity of its host range in India includes plants belonging to 278 species/subspecies under 68 plant families. Plants belonging to following families are highly infested: Asteraceae, Cucurbitaceae, Fabaceae, Lamiaceae, Malvaceae, Polygonaceae, Rosaceae, Rutaceae and Solanaceae.

The present study was carried out to determine the possible bioactive components of methanolic leaf extract of Magnolia nilagirica by using GC-MS analysis. The GC-MS analysis provides different peaks determining the presence of 55 compounds were identified from the leaf extract of M. nilagirica.

This study aimed to investigate the effect of Brilliant Blue and Dark Green food dyes on the Escherichia coli which is part of the intestinal flora.The food dye stock solution was prepared as 50 mg/ml with serum physiologic solution. Both of the food dyes were added in nutrient broth medium as 5, 2,5 and 1,25 mg/ml concentrations Design bacteria was inoculated inside of the dyes a 0.34 McFarland. After samples werewaitedin shaking incubator during 24 h, streaking was made to agar medium. In addition, RNA of control and sample groups were extracted forusing kits for molecular studying.

A total of 50 intestines of domestic chicken were collected in and around Cheyyar, Thiruvannamalai district from April 2014 to September 2014. The overall prevalence of parasitic infection was 91.54%. of this overall prevalence of 91.54%, 80.67% was infected with cestodes and 19.33% with nematodes. The collected tape worms (cetodes) were identified as Raillietina tetragona, R.echinobothridia, R.cesticillus, Cotugnia dionophora and Hymenolepis carioca) and nematodes were identified as Ascaridia galli and Heterakis gallinarum.
