Abstract: Background: Osteoporosis is a global public health problem affecting the ageing population and influenced by poor nutrition, lack of physical activities, and absence of supplementation on time. Objectives: To study the impact of Calcium and vitamin D supplementation along with weight bearing exercises on bone health status of elderly. Methods:30 elderly males and 20 elderly females having poor BMD and poor serum vitamin D were supplemented with 1000 mg calcium and 500 IU vitamin D/ day along with weight bearing exercises for a period of 3 months, along with that 60000 IU vitamin D3/week for 2 months were given to 30 males only. Serum calcium, Vitamin D, BMD, dietary calcium intake, frequency of vitamin D rich food intake, anthropometry etc. were measured at the baseline as well as after the intervention. Results: Mean BMD T-scores (-1.1 to -2.5: osteopenia; >-2.5: osteoporosis) of the elderly males and females were significantly (p≤0.001) decreased after the intervention depicting improvement (baseline:-2.34±0.50, final:-1.86±0.61). 26.7% reduction in osteoporotic cases among males and 50 % among women was achieved. Mean serum calcium (baseline: 9.38±0.63, final: 9.46±0.61) and vitamin D level (baseline: 23.76±13.17, final: 35.48±14.84) was increased significantly (p≤0.05). 60% males and 70% females achieved vitamin D sufficiency level after the intervention. Mean physical endurance (Grip strength, standing balance, walking speed and rise from chair) scores were significantly increased in both males and females. Locomotor problems were reduced among 6.7% males and 40% females after regular weight bearing exercise and supplementation. Conclusion:Calcium and vitamin D supplementation with daily weight bearing exercise has a preventive and curative effect on BMD and it maintains the serum calcium and vitamin D levels. Long term and high dose supplementation needs further investigation. Keywords: Elderly, BMD, Calcium, Vitamin D, Physical Activity.Download Full Article |

Abstract: he microorganisms play a vital role in fertility of soil and hence favors’ large group of plants. In present study we have successfully isolated certain bacteria from soil including both Gram positive and Gram negative bacteria and access their ability in phosphate solubilization. Effects of temperature, pH and different carbon sources, on phosphate solubilization, by these isolates were also determined. Low temperature 25 °C, pH between 5-7, and glucose as carbon source were found to be best for phosphate solubilization by most of the isolates. Present study highlights the importance of these plants growth promoting bacteria and their uses for agriculture purposes. Keywords: Phosphate solubilization, Plant growth promoting bacteria, Indigenous Soil, Temperature, pH and Carbon sources.Download Full Article |

Abstract: During this study, different blends of taro starch-hydrocolloid were incorporated in yeast leavened bread and their effects were investigated. The specific volume, moisture content and slice shape of the bread were found to be improved by the addition of taro starch-guar gum blend. Taro starch-xanthan gum mixture was also found to be a good additive to improve specific volume, slice shape, crumb softness as well as sensory characteristics of bread. The study reveals taro starch-hydrocolloid blend can be utilized as a novel ingredient to improve the physical and sensory characteristics of leavened bread.

Abstract: The methanol extract of chaga (sclerotia of Inonotus obliquus) inhibited the promoting effect of 12-O-tetradecanoylphorbol-13-acatate (TPA) applied twice weekly on skin tumor formation in mice initiated with 7,12-dimethylbenz [a] anthracene. The methanol extract from chaga led to the isolation of eight triterpenoids (1-8). The anti-inflammatory activity of the isolated lanostane-type triterpenes was evaluated against TPA-induced inflammatory ear edema in mice. These compounds showed markedly anti-inflammatory effects, with a 50% inhibitory dose of 125-458 nmol/ear. Keywords: Chaga, Inonotus obliquus, lanostane-type triterpene, antitumor promotion, anti-inflammation, two-stage carcinogenesis.Download Full Article |

Abstract: Toxicity study of Sanguinaria canadensis L. was determined as compared to Aloe vera (L.) Burm. f. against brine shrimp (Artemia salina). Upon statistical analysis of obtained toxicity bioassay data through the method of probits, LC50 of Sanguinaria canadensis was estimated as 0.021 mg/ml, with (95% C.I : 0.0091-0.0485) whereas Aloe vera was found to be almost non-toxic showing relatively higher LC50 that is, 180783.7 mg/ml. These results show that Aloe vera that is being used widely as an herbal medicine throughout the world, could be used safely for other various expected purposes for instance IPM etc. where the excessive amount is anticipated to drain into the sea ecosystem ultimately.
