Opis:
Histamine was discovered in the year 1910 and subsequently histamine toxicity was reported from several marine foods especially from fish. Detailed research has proved that different species of fishes are known to accumulate large quantity of histamine and the histamine is heat stable. Reason for the histamine toxicity was due to the consumption of fishes with high level of histamine. Ancient systems of medicine such as Ayurveda and Siddha are 5000 years old. Ayurveda and siddha clearly dictates the avoidance of fish by patients who suffer from various diseases such as psoriasis, vitiligo, eczema, urticaria, anemia, duodenal ulcer, irritable bowel syndrome, rheumatoid arthritis etc. In all the above diseases histamine is either the trigger or the cause of the disease, therefore reducing histamine burden is also one of the treatment strategies. Histamine toxicity in fish and sea foods are great concern and the histamine is harmful to many diseases. Ancient siddhars have advised the patients to suffer from various diseases to avoid fish may be due to histamine toxicity. In the light of the present revelation about histamine toxicity in fish and the fish avoidance prescription of Ayurveda and Siddha clearly indicates that the Ayurveda and Siddha scholars were clearly aware of histamine toxicity 5000 years ago. Details are presented in the paper.

Opis:
Coefficient of Variation (C.V) is a unitless measure of dispersion. Hence it is widely used in many scientific and social investigations. Although a lot of work has been done concerning C.V in the infinite population models, it has been neglected in the finite populations. Many areas of applications of C.V involves the finite populations like the use in official statistics and economic surveys of the World Bank. This has motivated us to propose six new estimators of the population C.V. In finite population studies regression estimators are widely used and the idea is exploited to propose the new estimators. Three of the proposed estimators are the regression estimators of the C.V for the study variable while the other three estimators makes use of the regression estimators of population mean and variance to estimate the ratio , the population C.V for the study variable. The bias and mean square error (MSE) of these estimators were derived for the simple random sampling design. The performance of these estimators is compared using two real life data sets. The simulation is carried out to compare the estimators in terms of coverage probability and the length of the confidence interval. The small sample comparison indicates that two of the proposed estimators perform better than the sample C.V. The regression estimator using the information on the Population C.V of the auxiliary variable emerges as the best estimator.

Opis:
Biofertilizers are the special formulation of specific beneficial microorganisms that promote the growth of plant crops by converting the unavailable form of nutrients into available form. Here, the effect of heavy metal stress on antioxidant enzymes were studied in Clitoria ternatea L. leaves. Clitoria ternatea L. plant was grown for 30 days and the heavy metal mercuric chloride was sprayed after 10 days from the date of planting. Effect of mercuric chloride was observed in treated plants. The selected plant Clitoria ternatea L. was grown under mercuric chloride treatment in a specified concentration 1 μg/10 ml. The control plant maintained without the treatment of mercuric chloride. Antioxidant effect of mercuric chloride was measured under controlled and treated conditions. The selected plant Clitoria ternatea L. was grown under mercuric chloride in treatment. Further it increases H2O2 content and the antioxidant enzyme activities such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) were observed in mercuric chloride treated plants when compared with control. Here mercuric chloride was accumulated more in matured leaves. The results are discussed with the literature.

Opis:
The plant Justicia simplex D.Don is traditional herb, people used it in different diseases, they treat fever and burning of the body, strengthen the lungs, the teeth and stop vomiting. The plant exhibited more promising bacterial activity against various microorganisms. Hence, in the present study this plant is also tested against the dental pathogens. The plant was extracted from four different solvents was tested for the presence of phytochemicals in it. After analyzing, its antimicrobial activity is tested against fungi and bacteria. Then a dental carrier Streptococcus aureus, Klebsiella pneumonia, Escherichia coli and Pseudomonas aeruginosa which was collected from the K.S.R. Institute for Dental Science and Research. The isolates were used to check the activity against Justicia simplex D.Don. Based on the positive result obtained against various analyses, it is formulated successfully into a tooth paste. The present study on Phytochemical screening of Justicia simplex D.Don a valuable medicinal plant extract against Dental pathogens enables the use of this plant for the formulation of tooth powder against dental pathogens. The result is more effective against dental pathogens by herbal tooth powder.
