Abstract

The therapeutic values of numerous plants and their herbal formulations were tested against a few chemical induced subclinical levels of liver damages in rodents and experiments have clearly shown that plants such as Picorrhiza kurroa, Andrographis paniculata, Eclipta alba, Phyllanthus maderaspatensis and Trichopus zeylanicus are sufficiently active against certain hepatotoxins. Screening plants for antihepatitis activities remains in its infancy. The Methanol extract of Blumea mollis were studied for their hepatoprotective effects on paracetamol induced acute liver damage on Wistar albino rats. The degree of protection was measured by using biochemical parameters such as serum glutamate oxalate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT), alkaline phosphatase (ALP and bilirubin Further, the effects of the extract on hepatic Glycogen (mg/100g tissue) GSH (µmlol/mg protein GST (u/g tissue), GPX (u/mg protein) GSH-R (mol NADPH min^-1/g tissue) were estimated. The Blumea mollis extracts produced significant (P<0.05) hepatoprotection by decreasing the activity of serum enzymes and bilirubin while it significantly increased the levels of Hepatic glycogen reduced glutathione (GSH) Glutathione-S-transferase (GST) glutathione peroxidase (GPX) and GSH-R in a dose dependent manner.

Abstract

The rates of daily average, minimum and maximum oxygen consumption, specific dynamic action (SDA), ingestion and digestibility in Panaeus indicus were measured before, during and after a gradual rise of water temperature from 25 to 31°C at ever 2°C interval. The relationship between energy again and the metabolic costs has also been investigated. Oxygen consumption of P. indicus showed a clear rhythmicity, with low levels during darkness and higher levels during the light period.

Abstract

Human interaction with the smart spaces is a rapidly developing field. This has been achieved by various means in the past, through wired or wireless modes of communication. In our proposed model we used MEMS device for finger movement detection, which can control the smart spaces. We develop communication between the system and human in a java environment and further bond them using a communication port to perform some operations in the system such as system logging off and logging on and the automatic control of camera along with sending a mail of real time image captured by the camera, controlling of home appliances like electrical connections, TV, fridge and automobile. These operations are performed without any tactile touch with the system. Our system consists of a transmitting block and receiving end. The transmitting side is in the form of a ring in our finger. The receiving end is the universal unit. Four hand gestures were given as input (left, right, up, down). For each of which a specified operation is performed.

Keywords

Abstract

Biofouling is a natural process of colonization of organisms on submerged surfaces, either living or artificial, by a wide range of microorganisms, plants, algae and animals. Biofilms on artificial structures create serious problems for industries worldwide, with effects such as increase in drag force and metal corrosion as well as reduction in heat transfer efficiency. For antifouling or preventing the attachment of fouling organisms, a knowledge of the microbial composition is of considerable importance. In the present study, biofouling samples were collected bimonthly from the boats docked at the Royapuram harbour, which is situated in northern Chennai. Culturable marine bacteria were isolated on Zobell's marine agar medium and identified by biochemical methods. The bacteria most frequently isolated were Bacillus spp., Vibrio spp., Pseudomonas spp., Micrococcus luteus, Proteus mirabilis and Shigella spp. The macrofouling community is dominated by barnacles, Mytilus spp.; green mussel, Perna viridis; polychaetes and other tubeworms. An analysis revealed that most of the marine bacteria are of anthropogenic origin. The stone crab Menippe mercenaria is reported as a macrofouler for the first time.

Abstract

Vibrios contribute the major part among water and foodborne pathogens in coastal ecosystems. The members of the family Vibrionaceae contribute 60% of the total bacterial population. The current work is aimed at the analysis of the presences of Vibrio species in edible oyster Crassostrea madrasensis along the coastal line of Chennai in Ennore, Royapuram and Muttukadu. The oysters were collected, and total heterotrophic bacteria were analysed using selective non-selective agar medium and further confirmed by biochemical tests. The predominant pathogenic halophilic Vibrio species were identified to generic level according to Bergey's Manual of Systematic Bacteriology. Among the Vibrios, Vibrio alginolyticus, V. parahaemolyticus and V. harveyi were the dominant species identified in Crassostrea madrasensis.

Abstract

The objective of this study is to comparatively analyse and assess the heavy metal pollution in coastal areas of Ennore and Royapuram, Tamilnadu, India. Ennore coast receives untreated/treated effluents from Manali Industrial belt, which houses many chemical Industries. Royapuram mainly receives domestic sewage. Analyses of water and mussel samples were done by ICP-AES. During summer all the dissolved heavy metals exhibited maximum values. The result shows that concentrations of copper, cadmium, zinc and lead were above the permissible limits.

Keywords
