We aimed to estimate metabolic bone profile in a large cohort of healthy, adult Indian population to generate reference standards of serum calcium, phosphate and alkaline phosphatase (ALP), 25 (OH) Vitamin D and iPTH, and also to find out the prevalence of Vitamin D deficiency in healthy population. Apparently healthy people in the age group of 20–80 years, residing in the union territory of Chandigarh were chosen. Fasting samples for serum calcium, phosphate, albumin, alkaline phosphatase (ALP), 25 (OH) D and iPTH were collected and were processed on the same day. We recruited 930 healthy subjects from different subsectors of Chandigarh. Final analysis was done for 915 subjects. Out of this, 530 (58%) were women and 385 (42%) were men. The study participants were divided into two groups, less than and more than 50 years for the men and pre and post-menopausal for the women. The serum calcium, phosphate, ALP and iPTH were significantly higher in the post-menopausal women compared to the pre-menopausal women. The median plasma 25 (OH) D in men and women was 12.5 ng/mL and 14.3 ng/mL, respectively. 25 (OH) D deficiency was seen in 65.4% of individuals. 25 (OH) D levels co-related negatively with iPTH levels (r = − 0.4, p < 0.0001), and showed an increasing trend with age. We have thus presented metabolic bone profile of healthy, adult north Indian population. These reference values can be used for diagnosis and monitoring of various MBDs. Vitamin D deficiency is still rampant in our population in spite of increasing awareness.  相似文献

Chemoprotective Role of Triphala Against 1,2-Dimethylhydrazine Dihydrochloride Induced Carcinogenic Damage to Mouse Liver     

Sharma A  Sharma KK 《Indian journal of clinical biochemistry : IJCB》2011,26(3):290-295

The present study was carried out to investigate the protective role of Triphala (a combination in equal proportions by weight of fruit powder of Terminalia belerica, Terminalia chebula and Emblica officinalis) against 1,2-dimethylhydrazinedihydrochloride (DMH) induced Endoplasmic reticulum stress (ER stress) in mouse liver. An oral dose of 3 mg/kg body wt in drinking water for 5 weeks significantly (P < 0.001) increased the levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum Alkaline phosphatase (ALP) and total bilirubin thus suggesting damage to mouse liver and biliary dysfunction. The DMH administration invariably led to increase in the liver microsomal proteins of molecular weight of about 29 (ERp29) and 53 kDa (ERp53) and decrease in the protein of molecular weight of 36 kDa (ERp36) thereby suggesting the interference of DMH and its metabolites with normal protein biosynthesis and folding, in the reticular membranes of the liver cells thus developing ER stress. Histological studies show necrosis, large sized hepatocytes with increased N:C ratio, aberrant mitotic figures and prominent nucleoli in the liver of DMH treated mice. In animals fed 5% Triphala in diet (w/w) during DMH administration, there was significant decrease in the above changes in the liver suggesting the suppression of DMH induced ER stress in liver. Triphala significantly (P < 0.05) decreased lipid peroxidation and also the activity of lactate dehydrogenase (LDH) in mouse liver. It simultaneously increased the level of reduced glutathione (GSH) and the activity of glutathione-S-transferase (GST) thereby suggesting that it prevents peroxidative damage and also diverts the active metabolites (electrophiles) of DMH from their interactions with critical cellular bio-molecules which could be responsible for its protective action against DMH.  相似文献   

Effect of wall permittivity on electroviscous flow through a contraction     

Berry JD  Davidson MR  Bharti RP  Harvie DJ 《Biomicrofluidics》2011,5(4):44102-4410217

The electroviscous flow at low Reynolds number through a two-dimensional slit contraction with electric double-layer overlap is investigated numerically for cases where the permittivity of the wall material is significant in comparison with the permittivity of the liquid. The liquid-solid interface is assumed to have uniform surface-charge density. It is demonstrated that a finite wall permittivity has a marked effect on the distribution of ions in and around the contraction, with a significant build-up of counter-ions observed at the back-step. The development length of the flow increases substantially as the wall permittivity becomes significant, meaning that the electric double-layers require a longer distance to develop within the contraction. Consequently, there is a corresponding decrease in the hydrodynamic and electro-potential resistance caused by the contraction. The effect of wall-region width on the flow characteristics is also quantified, demonstrating that the development length increases with increasing wall-region width for widths up to 5 channel widths.  相似文献   

Measuring physical activity in preschoolers: Reliability and validity of The System for Observing Fitness Instruction Time for Preschoolers (SOFIT-P)     

Sharma S  Chuang RJ  Skala K  Atteberry H 《Measurement in physical education and exercise science》2011,15(4):257-273

The purpose of this study is describe the initial feasibility, reliability, and validity of an instrument to measure physical activity in preschoolers using direct observation. The System for Observing Fitness Instruction Time for Preschoolers was developed and tested among 3- to 6-year-old children over fall 2008 for feasibility and reliability (Phase I, n=67) and in fall 2009 for concurrent validity (Phase II, n=27). Phase I showed that preschoolers spent >75% of their active time at preschool in light physical activity. The mean inter-observer agreements scores were ≥.75 for physical activity level and type. Correlation coefficients, measuring construct validity between the lesson context and physical activity types with and with the activity levels, were moderately strong. Phase II showed moderately strong correlations ranging from .50 to .54 between the System for Observing Fitness Instruction Time for Preschoolers and Actigraph accelerometers for physical activity levels. The System for Observing Fitness Instruction Time for Preschoolers shows promising initial results as a new method for measuring physical activity among preschoolers.  相似文献

A study of thyroid status in hyperemesis gravidarum     

Bhupinder Kaur Gill  Promila Jindal  Raj Kumar  Shweta Tiwari  Namrata Sharma  Anupama Goel 《Indian journal of clinical biochemistry : IJCB》2007,22(1):148-151

Study was undertaken to assess thyroid status in hyperemesis gravidarum. 150 women pregnant with <20 weeks of gestation were selected randomly and out of these 100 women presenting with hyperemesis formed study group while 50 normal pregnant women served as controls. 53% of hyperemetic pregnant women were primigravidae and 82% of pregnant women presented with vomiting at less than 12 weeks of gestation. Statistically significant, 22% of hyperemetic women had increased serum T₃ levels while T₄ levels were increased in 67% of women in study group as compared to 8% and 16% respectively in control group. TSH levels were decreased in 18% of hyperemetic women as compared to 8% in control group with decrease in mean TSH level statistically significant. 22% of hyperemetic women had electrolyte disturbances and 7% were ketonuric. In clinically euthyroid women, biochemically altered thyroid function can attribute to vomiting and its prolongation to second trimester  相似文献   

Influence of alcoholic extract of whole fruit of trichosanthes dioica on blood sugar,serum lipids,lipoproteins and faecal sterols in normal albino rabbits     

Govind Sharma  M. C. Pant 《Indian journal of clinical biochemistry : IJCB》1992,7(1):53-56

Effect of oral administration of 2 ml per day of suspension (in water) of alcoholic extract of whole fruit of Trichosanthes dioica (2%) (=100 g fresh wt.=7 g dry wt.=1/15 g of alcoholic extract) with the help of catheter alongwith basal diet for four weeks have been studied in the normal albino rabbits. It was observed that this extract lowered the blood sugar, total cholesterol, low density lipoprotein cholesterol and triglyceride levels, and increased the high density lipoprotein cholesterol, phospholipid and faecal sterol levels. Such effects are manifested from the very first week of feeding and are statistically significant.  相似文献
