Abstract
The integration of nanomaterial with biology is finding wide applicability in various areas of medical sciences. Recently, silver nanoparticles have gained attention because of their antimicrobial activity which offers the possibility of their use for medical purposes. Metallic nanoparticles can be obtained by physical, chemical or biological methods. But silver nanoparticles synthesized by chemical reduction methods are found to be toxic, flammable and not at all eco-friendly. Therefore in the present study, an attempt was made to formulate a cost effective and environment friendly technique for green synthesis of silver nanoparticles. The silver nanoparticles were synthesized using extract of Phyllanthus amarus with AgNo3 solution . Their antibacterial activity was studied using agarwell diffusion method on isolates viz., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis, Enterobacter obtained from patients suffering from urinary tract infection. The antibacterial efficacy of silver nanoparticles of Phyllanthus amarus was found to be superior to that of hot or cold extracts of Phyllanthus amarus silver nanoparticles were characterized by UV-Vis spectroscopy and scanning electron microscopy (for particles size analysis). This work demonstrates the possible use of biologically synthesized silver nanoparticles to treat urinary tract infections.

IN VITRO ANTIOXIDANT ACTIVITY, TOTAL PHENOL AND TOTAL FLAVONOID CONTENT OF Orthosiphon aristatus (Blume). Miq.
Abstract
The aim of this was to examine the antioxidant activity, total phenol and total flavonoid content of the leaf of Orthosiphon aristatus collected from three distant regions of Tamil Nadu namely Azhizar, Trichy, Chengalpattu. These were examined using extracts of aqueous, ethanol, acetone, chloroform and petroleum ether. The leaf extracts were evaluated for antioxidant activities by DPPH (1,1 – diphenyl -2- picryl-hydrazyl) radical scavenging assay. Among three accessions with different solvents used, maximum antioxidant activity was found in ethanolic leaf extract 85.2% from cuddalor followed by others. Total phenol and flavonoid content was quantitatively estimated, the ethanolic leaf extract of Orthosiphon aristatus was found maximum in Azhiyar accessions (17.13 mg Gallic Acid Equivalents (GAE)/g and 9.30 mg Quercetin Equivalents (QE) /g). The powerful antioxidant activity is attributed to the greater amount of total phenol and flavonoid compound in the ethanolic leaf extract ofOrthosiphon aristatus
Customer perception on credit portfolio – A Study with reference to Primary Co-operative Agriculture and Rural Development Bank in Mayilduthurai Town.
Abstract
Agriculture, in spite of its importance, suffers from many deficiencies such as of value addition process, its dwindling share in Net Domestic Product (NDP) and the declining productivity of agriculture in general and lack of development of a viable organizational mechanism at the grass root level which can undertake planning and co-ordination. This calls for the need to develop the villages at the grass root level, which holds the key for economic development .Considering these, the Eighth Five Year Plan has given emphasis to agricultural and rural development .It is hoped that a provision of adequate credit to this sector will help in taking off agriculture from the present deteriorating stage. “India lives in villages” is true even to this day. The Land Development Banks structure has a history of eight decades in India. But such banks were not in existence in some states till independence of India. The first Land Mortgage Bank was set up in 1920 at Jahangir in the state of Punjab. In 1996-97 these LDB’s renamed as Primary Co-operative Agriculture and Rural Development Banks (PCARDBs) in most of the states. The present study is undertaken to analyses the Customer perception with credit portfolio in primary co-operative agricultural rural development bank.

A Study on Problem and Issues of the Primary Co-operative Agriculture and Rural Development Bank in Mayilduthurai Town.
Abstract
Agriculture in a narrow sense is referred to crop production while in its wider sense it includes other allied activities where biological transformation is the process of production. Following the definition of National Commission on Agriculture, “It includes activities like cultivation of crops, cattle rearing and dairy farming, raising piggery and poultry and development of fishery and forestry and also activities connected with their improvements, while maximization of output through modernization of agriculture and allied activities is termed as agriculture development”. “India lives in villages” is true even to this day.” The Land Development Banks structure has a history of eight decades in India. But such banks were not in existence in some states till independence of India. The first Land Mortgage Bank was set up in 1920 at Jhang in the state of Punjab. In 1996-97 these LDB’s renamed as Primary Co-operative Agriculture and Rural Development Banks (PCARDBs) in most of the states. The present study is undertaken to analyses the recovery performance of loans and the reasons for default repayment by the borrowers in primary co-operative agricultural rural development bank.
EFFECT OF ORGANIC AND INORGANIC FARTILIZERS ON GERMINATION PERCENTAGE AND SEEDLING CHARACTERS OF SUNFLOWER
Abstract
The present study examined the effects of organic and inorganic fertilizers on germination percentage, shoot length and root length, whole plant fresh and dry weight of sunflower plants. There are four sources of organic fertilizer: Agricultural waste compost, market waste compost, paper waste compost and their combined treatment. While, N,P,K and their combination treatments were used as the source of inorganic fertilizers. The results observed that, the combined treatment of organic fertilizer shows highest percent of germination followed by N+P+K, when compared to individual treatments and control. The treatment with organic fertilizers is found to be more effective than the inorganic fertilizer in sunflower plant.

IMPACT OF HEAVY METAL, CHROMIUM ON GLYCOGEN CONTENTS IN GILL, LIVER AND KIDNEY OF FRESHWATER FISH, Channa striatus (BLOCH)
Abstract
Fish is generally appreciated as one of the healthiest and cheapest source of protein and it has amino acid compositions that are higher in cysteine than most other sources of protein. Heavy metals are natural trace components of the aquatic environment but their levels have increased due to industrial wastes, geochemical structure, agricultural and mining activities. All these sources of pollution affect the physiochemical characteristics of the water, sediment and biological components and subsequently affect the quality and quantity of fish stocks. The chromium is present in the tannery effluent and is known to cause various ill effects. Such health hazards are dependent on the oxidation state of chromium. Its hexavalent form is more toxic than the trivalent form. The aim of the present study was to assess the glycogen contents in gill, liver and kidney of Channa striatus was exposed to sublethal concentrations of chromium for the period of 10, 20 and 30 days. The fish exposed to chromium showed a decreased the glycogen contents for 10, 20 and 30 days in gill, liver and kidney. The objective of the present investigation was to observe the effect of chromium on glycogen contents in the gill, liver and kidney of freshwater fish, Channa striatus.
