Estimation of accidental gaps in the data on Sample survey of marine fish landings

In sample surveys carried out to estimate the monthly marine fish landings, instances often arise when the relevant data in parts are lacking. A statistical method for the estimation of such gaps has been developed which seems to meet the requirement within limits

Problem of nonadditivity in two-way analysis of variance of data for comparing the efficiency of fishing gears

To bring out the relative efficiency of various types of fishing gears, in the analysis of catch data, a combination of Tukey's test, consequent transformation and graphical analysis for outlier elimination has been introduced, which can be advantageously used for applying ANOVA techniques, Application of these procedures to actual sets of data showed that nonadditivity in the data was caused by either the presence of outliers, or the absence of a suitable transformation or both

Antifungal activity of ethanolic extract of Sphaeranthus indicus Linn. against Dermatophytes and Candida species

Background: Sphaeranthus indicus as an entire plant or the specific parts like roots, leaves, flowers are used for treating helminthiasis, jaundice, diabetes, dyspepsia, fever, cough, hernia, gastritis, hemorrhoids, migraine, leprosy and skin diseases. The objective of this study was to evaluate the antifungal activity of ethanolic extract of the whole plant Sphaeranthus indicus Linn. Methods: The antifungal activity of ethanolic extract of the whole plant Sphaeranthus indicus Linn was evaluated by incorporating the extract in Sabourauds dextrose agar. This property was studied in vitro using the ethanolic extract on Candida albicans, Microsporum gypseum, Trichophyton mentagrophytes and Epidermophyton floccosum by using Clotrimazole as standard drug.Results: This study revealed that the ethanolic extract of Sphaeranthus indicus is having good antifungal activity against Dermatophytes and Candida species. Conclusions: This study demonstrates the promising antifungal action of ethanolic extract of whole plant of Sphaeranthus indicus Linn. This feature can be exploited in the development of a newer antifungal agent from plant.

In vitro evaluation of antibacterial activity in ethanolic extract of whole plant Sphaeranthus indicus Linn.

Background: Sphaeranthus indicus Linn is a widely used medicinal plant in Indian traditional system of medicine against human pathogens. Alarming bacterial resistance is urging scientist to search for newer anti-microbial substances from the medicinal plants. The objective of the study was to evaluate the antibacterial activity of ethanolic extract of the whole plant Sphaeranthus indicus Linn (Asteraceae).Methods: The antibacterial activity of ethanolic extract of whole plant of Sphaeranthus indicus Linn was done against Escherichia coli, Pseudomonas aeruginosa, Proteus mirabilis and Staphylococcus aureus in Mueller Hinton Agar (MHA) and compared with ciprofloxacin as standard by disc diffusion method.Results: The study revealed that there was no zone of inhibition in doses of 100 mcg, 200 mcg and 300 mcg of ethanolic whole plant extract of Sphaeranthus indicus in MHA plates compared with ciprofloxacin 30 mcg.Conclusions: Ethanolic extract of Sphaeranthus indicus does not have antibacterial activity. Further studies are needed in different extracts and parts of the plant. Simultaneous studies can be done in different places to evaluate environmental factors and regional variations

Plankton production in the Vembanad Lake and adjacent waters in relation to the environmental parameters

The Vembanad Lake and its connected backwater system around Cochin are well known as the nursery grounds for the commercially important fishery resources of this area. This account embodies the results of studies on the environmental parameters of the estuarine system around Cocb in extending over an area of 300 sq. km. Observations were made on the hydrography, primary and secondary productions. The relative influence of the environmental factors like, temperature, salinity, dissolved oxygen and nutrients on the plankton production is interpreted from the correlation coefficient

Sodium Alginate Based Mucoadhesive System for Gatifloxacin and Its In Vitro Antibacterial Activity

The objective of this study was to formulate sodium alginate based ophthalmic mucoadhesive system of gatifloxacin and its in vitro antibacterial potential on pathogenic microorganisms, Staphylococcus aureus and Escherichia coli. Sodium carboxymethylcellulose (NaCMC) was added to the formulations to enhance the gel bioadhesion properties. The prepared formulations were evaluated for their in vitro drug release, gelation behaviour, rheological behavior, and mucoadhesion force. All formulations in non-physiological and physiological condition showed pseudo plastic behavior. Increase in the concentration of sodium alginate and sodium CMC enhanced the mucoadhesive force significantly. In vitro release of gatifloxacin from the system in simulated tear fluid (STF, pH – 7.4), was influenced significantly by the properties and concentration of sodium alginate, NaCMC. Significant reduction in total bacterial count was observed between control and treatment groups with both the test organisms

Japanese defence policy since 1976: latest trends

This study sets Japan's defence posture in the context of world politics, especially in regard to the Soviet Union and the United States. The different perceptions of defence by different groups of people in Japan (the man on the street, the political parties and business groups) are discussed. The gradual development from a heavy dependence on the United States for defence is slowly progressing towards a more equal sharing of defence responsibilities between the United States and Japan. The author points out the practical necessities for this change, the pressures that the United States is putting on Japan to carry out this change, and also the problems and fears that arise in Japan because of this pressure. Specific topics covered include the development of defence production industries in Japan, the exchange of weapons technology with the United States, Japan's ability to defend her sea lanes, the concept of collective defence responsibility and the diverse opinions aroused both in Japan itself and in neighbouring countries in regard to these developments. The author has added an addendum since the publication of the 1983 Japanese Defence White Paper, the reaction to which again emphasises the difficulties Japanese defence planners and politicians face in trying to achieve a balanced defence policy
