Background and Objective: Pesticides are hazardous to human beings, flora, fauna and ecosystems. Though they are applied to increase the productivity in crop fields for controlling pests, they cause pollution in air, water and soil. Bioremediation is employed to clean polluted sites using organisms. Microbes are ubiquitous and some of them can degrade pesticides. Hence the present study has been designed to isolate a bacterial strain capable of degrading methyl parathion and to test its efficiency of degradation. Materials and Methods: Soil samples collected from contaminated crop fields were subjected to serial dilution, plating and incubation. From the grown colonies one colony was chosen and it was identified using biochemical tests. It was tested for its efficiency after exposing to 50, 100, 150 and 200 ppm for 30 h by monitoring changes in pH, orthophosphate, turbidity and the influence of sugars and immobilization. UV-visible spectrophotometry, HPLC analysis and statistical analysis were carried out to confirm the degradation efficiency of the natural isolate. Results: The natural isolate was identified as Pseudomonas aeruginosa based on the results of biochemical tests. Maximum orthophosphate was released in 200 ppm methyl parathion. The pH declined during degradation while turbidity exhibited an increase which indirectly indicated the degradation by the natural isolate. Orthophosphate level increased steadily when immobilized cells were tested. All the tested carbohydrates enhanced the release of orthophosphate. Both UV-visible spectrophotometry and HPLC analysis confirmed the degradation of the pesticide by the natural isolate. Conclusion: The natural isolate can be used to degrade pesticides like methyl parathion and its capacity can be enhanced by immobilization or supplementation with carbohydrates. |

Immuno-modulators play a key role in immunity of each animal in this world. Almost all animals have their own system to produce different immuno-modulators at different time. This review focuses on the use of a variety of natural products/drugs in the enhancement and suppression of impaired immune system under unfavorable conditions. The main accent of this review is to emphasize on the need to evaluate the potential of Indian Ayurvedic remedies as adjuvants to counteract side effects of modern therapies. This study also highlights on the process involved in drug discovery from plant extracts in India. The review assigned a brief discussion on past and present scenario of herbal medicines in India with some important recommendations, suggestions and future directions in this area of herbal medicines. |

To assess the nutritional status of toddlers of different
villages of Niwai tehsil, Dist-Tonk, Rajasthan. Toddler aged 1-3 years were
selected through random sampling from villages of Niwai Tehsil, District-Tonk,
Rajasthan. Anthropometric measurements were taken according to standard procedures
and dietary survey was done through 24 h recall method for 3 consecutive days.
Hemoglobin level was measured by cyanomethnoglobin method. Overall, scenario
of anthropometric measurements have revealed that according to weight for age,
height for age and weight for height 20, 40 and 12% were normal respectively
while 42, 43 and 16% were normal according to MUAC, head/chest circumference
ratio, tricep’s skin fold thickness. Results of clinical examination shown
that sign and symptoms of protein energy malnutrition as flag sign, dull and
dry hairs, skin pigmentation, bitot’s spot in the form of vitamin A deficiency
were prevalent and dietary intake was less than recommended dietary allowances.
About 75% of children were found to be anaemic. The nutritional status of children
in rural communities is affected by low family income and behavioral problems.
To improve nutritional status of children the full implementation of the poverty
alleviation programmes should be considered and appropriate measures need to
be taken to support needy families with children. Appropriate measures should
be taken by the respective authorities to improve childhood health and nutritional
status. |

Soybean and watermelon seeds are rich source of protein as well as minerals mainly iron yet they are not consumed by a large number of populations instead of their nutritional qualities. Guava is a rich source of ascorbic acid. The objective of the present study was to prepare nutritionally enhanced ice creams by the incorporation of soy milk, watermelon seeds milk and guava pulp and evaluation of their acceptability and nourishing potential. Total six different types of ice creams were prepared from soy milk, watermelon seed’s milk as whole and their blends with or without addition of guava pulp. At 9-point Hedonic scale products were evaluated for their appearance, flavor, mouth feel and overall acceptability in which most of the ice creams were liked moderately to very much and one ice cream were most acceptable, i.e., blended milk (50% soy milk and watermelon seed milk) ice cream with guava pulp. The nutritional analysis of most acceptable ice creams indicated that protein and fat value was found to be excellent and iron as well as vitamin C content were also found in good amount in comparison to standard cow’s milk ice cream. Thus, these ice creams would be highly nutritious and acceptable by the population. |

Obesity is one of the most common metabolic and nutritional
diseases. The effect of obesity of children has a wide spectrum of adverse effects
that can rage from low self-esteem to increased risk of many degenerative diseases.
So, present study was conducted in different schools of Dehradun city to find
out prevalence of obesity among children (10-12 years) in different schools
and its variability according to economical status, eating practices and physical
activities. The study was conducted to assess the prevalence of obesity among
children (10-12 years of age) from 8 different schools, having students coming
from low as well as high economic status families. Selection of schools was
done on the basis of their fee structure. The general information about age,
sex, parent’s occupation and
number of family members with anthropometric measurements like height, weight,
waist circumference, hip circumference, MUAC taken and compared with NCHS-3
standards. Calculation of BMI and WHR was also done. Nutrients intake was noted
by 24 h dietary recall method. The physical activity pattern was also noted.
It was found that there were more percentage of obese and overweight children
in affluent class as their energy, protein, carbohydrate and calcium intake
was higher. Also, they are less engaged in energy consuming activities. Increasing
affluence, over-consumption of calories and reduced physical activity are noted
which result in childhood obesity. |
