Hence, the present study was carried out to know about the tolerance, sensitivity of the plants located in the experimental site. Method: Aqueous leaf extract was used for the whole study. Biochemical components, secondary metabolites, antioxidant activities were assessed by following standard procedures. Fresh leaves were collected from the study area daily until the completion of the study. The collected leaves were weighed with dust and without dust i.e after cleaning. The difference gives an idea about the pollution load in the particular place. Results: The ascorbic acid content was high with Tecoma stans, all the other plants showed

Plants produce antioxidant compounds like carotenoids, flavonoids, ascorbic acid, etc. to prevent the oxidation of the susceptible substrate. Hence, it was decided to assess the biochemical parameters. At the same times measures were taken to study the secondary metabolites as well as antioxidant activity. The results of the air pollution tolerance index studied showed, that Calophyllum inophyllum plant exhibited highest air pollution tolerance index of 19.26. The protein content was higher for Azadirachta indica showing 24.20 ± 1.55 mg/g followed by Albizia saman showing 16.80 ± 3.81 mg/g. Ficus religiosa showing carotenoid content of 10.39 ± 3.15 mg/g. The soil nitrogen, potassium content was found to be moderate showing 116.42, 112.04 kg/acre, whereas, phosphorus content was low showing 14.09 kg/acre. The total mineral content was found to be 242.55. The total phenolic content was higher with Syzygium cumini (25.26 ± 3.34 mg/g) and Albizia saman (25.53±7.04 mg/g). The flavonoid content was higher with Millettia pinnata showing 19.46 ± 0.57 mg/g. The total antioxidant activity of Syzygium cumini was found to be 20.13 ± 6.00 mg/g followed by Prosopis juliflora 20.00 ± 01.73 mg/g. The nitric oxide scavenging activity was same for the plants studied. The reducing power activity was found to be 13.86 ± 08.19 mg/g for Syzygium cumini and 13.33 ± 08.00 mg/g for Azadirachta indica. Metal chelating activity was found to be high with almost all the plants studied. The variation in the observed result might be due to the solubility of the components in the solvent selected.

Plants are playing a vital role in hepatoprotective activity. In this present investigation we used Solanum nigrum for the antimicrobial activity and hepatoprotective activity against acetaminophen induced liver toxicity in male albino rats. The important chemical groups present in the aqueous extract canbe determined using Fourier transform infrared spectroscopy (FT-IR). Zone of inhibition in bacterial spread plate showing a antimicrobial property of the plant extract. The aqueous extract of Solanum nigrum significantly decreases the serum enzyme alanine amino transferase (ALT), asparate amino transferase (AST), triglycerides (TGL), total cholesterol (TC) and significantly increased the total protein level. Silymarin (100 mg/kg), a known hepatoprotective drug used for comparison exhibited significant activity. The morphology of liver cells clearly indicating the treatment of Solanum nigrum against acetaminophen induced liver damage near to normal cells.

The aim of the present experiments was to determine the cellular synthesis of NO in the CNS immediately after injury, using the CNS of the leech which is capable of synapse regeneration, as a step towards understanding the role of NO in nerve repair. We report that within minutes after crushing the nerve cord of the leech, the region of damage stained histochemically for NADPH diaphorase, which is indicative of nitric oxide synthase (NOS) activity, and was immunoreactive for endothelial NOS (eNOS). On immunoblots of leech CNS extract, the same antibody detected a band with a relative molecular mass of 140,000, which is approximately the size of vertebrate eNOS. Cells expressing eNOS immunoreactivity as a result of injury were identified after freezing nerve cords, a procedure that produced less tissue distortion than mechanical crushing. Immunoreactive cells included connective glia and some microglia. Calmodulin was necessary for the eNOS immunoreactivity: it was blocked by calmodulin antagonist W7 (25 microM), but not by similar concentrations of the less potent calmodulin antagonist W12. Thus in the leech CNS, in which axon and synapse regeneration is successful, an increase in NOS activity at lesions appears to be among the earliest responses to injury and may be important for repair of axons.

The effect of horizontal wells on flood profile has been investigated by using two different well configurations, viz., horizontal injection-vertical production (HI-VP) and vertical injection-horizontal production (VI-HP). The experimental results show that HI-VP configuration recovers more oil than VI-HP configuration. The commercial simulator, ECLIPSE, is used for simulating the flood profiles for these well configurations. A good agreement is observed with the experimental flood profiles. Further simulations are carried out with varied perforation lengths and well positions to find out the optimal well configuration for both HI-VP and VI-HP. Such flow visualization experiments can be used as a validation tool for numerical simulators.
