Sixteen Harnai males were used to evaluate the influence of varying levels of fourwing saltbush hay on feed and water intakes as well as the blood serum mineral status in a completely randomized design. The animals were grouped randomly into four, with four animals in each. The four groups were randomly allotted low, medium, high and very high levels of saltbush hay supplementation in addition to wheat straw. The animals were given fresh water at free of choice. Weekly body weight was recorded for each individual animal. Blood serum was collected for mineral contents. The experiment lasted for eight weeks. The inclusion of saltbush leaves in the diet showed a non-significant effect on the total dry matter intake. There has been a significant increase in the water intake when very high levels of saltbush were included in the ration. Lower levels showed no effect on the water intake. The animals maintained their body weight from week 1 to week 8. No treatment by weeks interactions on the potassium and sodium levels were detected. However higher levels of saltbush increased significantly the potassium and sodium contents in the serum. Calcium contents were significantly(p<0.01) lowered with the inclusion of saltbush leaves in the diet. Whereas Phosphorous contents showed an increasing(p<0.05) trend with the higher levels of saltbush. No clinical or sub-clinical toxicological symptoms were observed in the sheep with the higher mineral contents.

This study was designed to investigate the effect of increased blood and tibia lead on the change of bone mineral density in retired male lead workers. One hundred nine retired male lead workers who worked in 4 different lead industries and 51 nonoccupationally lead exposed male subjects were recruited from March 2004 to October 2004. Bone mineral density(BMD) was measured by broadband ultrasound attenuation(BUA) at left calcaneous bone area with broadband ultrasound attenuation method of QUS-2(Metra Biosystems Inc, USA). Tibia bone lead was measured for skeletal bone lead with K-xray fluorescence(K-XRF) and blood lead was analyzed with flameless atomic spectrophotometer. Hemoglobin, hematocrit, serum calcium and iron were also analyzed. In addition, information for smoking and drinking status and basic personal data such as age and lead exposure were also collected using questionnaire inquiry. Blood lead was correlated with tibia lead (r=0.711) and these two variables were negatively correlated with BUA in bivariate analysis. BUA and tibia lead showed significant main effects on the change of blood lead after adjusting covariates. The effect modification by the level of BMD (low: lower than the median of BUA and high: higher than the median of BUA) was observed between the association of tibia lead and blood lead after adjustment of covariates. The subjects who had higher BMD seemed to have lower blood lead by the increase of tibia lead than those of lower BMD. In the multiple regression analysis of blood lead and tibia lead on BUA after adjustment of covariates, only blood lead showed statistically significant effect on BUA. This study confirmed that BMD and blood lead were significantly associated. To verify the causal association of BMD on blood lead and vice versa, further longitudinal studies are needed.

Objectives: This study was carried out to investigate bone mineral density (BMD), blood pressure, age and biochemical index and nutrient intakes, and to analyze the relationship between BMD, blood pressure, biochemical index, nutrient intakes of Korean women. Methods: The study subjects were 499 women with a age range of 30-79 years living in Seoul and Kyunggi area who participated in 2011 KNHANES. The study subjects were divided into 5 age groups : 30 years (145), 40 years (110), 50 years (102), 60 years (85) and 70 years (57), and 3 BMD groups: normal 258 (50.4%), osteopenia 163 (32.9%) and osteoporosis 78 (16.7%). Results: The average waist circumference, BMI and body fat increased with age, but fat free mass decreased with age. Average BMD and T-score was decreased from 0.84, $0.74g/cm^2$ in 30 years to 0.05, $-1.05g/cm^2$ in 70 years. The rates of osteopenia and osteoporosis increased significantly 22% in 30~40 years, 47% in 50 years and 56% in 60~70 years. Systolic blood pressure and cholesterol were significantly increased with age. The rates of hypertension was significantly increased 2.1% in 30 years, 30.4% in 50 years 89.5% in 70 years. Average nutrient intakes such as protein, calcium, iron, vitamin A and C were significantly decreased with age. There were significant negative correlations between age and calcium, systolic blood pressure, triglyceride. Conclusions: In this study, we found the risk of osteoporosis and hypertension were significantly increase with over 50 years age. Calcium and protein intake decreased with age. Therefore, in order to prevent osteoporosis and hypertension, adult women need to be educated regarding the importance of protein, calcium and other nutrients in their diet.

An experiment was conducted to investigate the effects of calcium (Ca) fertilization on oxalate content in napiergrass (Pennisetum purpureum) and on some blood parameters of sheep. Re-growth napiergrass was grown with or without Ca fertilizer and offered to sheep. Eight sheep, divided into two groups of 4 animals each were used. Calcium-fertilized napiergrass was offered daily to the animals as experimental treatment, whereas without Ca-fertilized napiergrass was given to the animals as control. Results showed that there was a trend to lower soluble and total oxalate concentrations in Ca-fertilized grass than control. The Ca-fertilized grass contained (p<0.05) lower concentrations of K and Mg than control, though Ca fertilization had no affect (p>0.05) on Ca and Na concentrations in plants. Feeding of Ca-fertilized grass had no affect on the feed consumption, blood Mg level and daily gain of sheep. However, sheep fed control grass had lower (p<0.05) blood Ca level than sheep fed Ca-fertilized grass. Our findings suggest that Ca fertilization might minimize the negative effects of oxalate.

This study was performed from April, 2007 to August, 2012 with female patients who were being treated for and suffering from chronic lumbar pain for periods of 6 months and over. The 53 female patients were diagnosed with osteoporosis by having a T-Score of <-2.5 in a bone mineral density(BMD), as well as showing signs of metabolic syndrome. This was deduced by taking measurements of blood pressure, carrying out blood-chemical examinations and physical measurements such as weight, height, waist measurement and body mass index(BMI). After 5 minutes rest, the patient's blood pressure, height and weight were measured. BMI was calculated using the equation BMI = weight (Kg)/height ($m^2$). The patients had their blood taken in a fasted state(more than 12hours), the fasting blood sugar, total cholesterol, triglyceride, HDL-cholesterol were measured. The average BMD and T-score were calculated by measuring BMD(mg/cc) of L1-L3 using QCT. In a correlation analysis of the physical examinations, clinical character of metabolic syndrome and T-score, the result showed that age and T-score had a negative correlation(r=-0.699, p<0.01) as did triglyceride and T-score (r=-0.047, p<0.01), where as weight(r=0.239, p<0.05) and height(r-=0.329, p<0.01) and T-score had a positive correlation. There was no significant correlation with total cholesterol, HDL cholesterol, blood sugar, blood pressure and T-score. This study showed that there are significant correlations with age, weight, height and T-score. But there are no significant correlations with total cholesterol, HDL cholesterol, blood sugar, blood pressure and T-score and that these did not influence bone density. Further research with more subjects is required to determine whether there is a correlation of clinical character of metabolic syndrome and T-score.

In order to investigate the effect of different sources of energy on intake and nutrient utilization from urea molasses mineral block (UMMB), rumen fermentation pattern and blood biochemical constituents, 18 intact and 9 rumen fistulated male Murrah buffaloes aged about 3 years and average weight 310.8 kg were randomly allocated into three groups of 9 animals in each, thus each group having 6 intact and three rumen fistulated buffaloes. All animals were fed individually for 90 days. All buffaloes were offered wheat straw as basal roughage and urea molasses mineral block for free choice of licking. Three different energy sources viz., barley grain, (group I), maize grain (group II) and jowar green (group III) were offered to meet their nutrient requirement as per Kearl (1982). At the end of feeding trial, a metabolism trial of 7 days duration was carried out on intact animals to determine the digestibility of nutrients. Rumen fermentation studies were carried out on rumen fistulated animals. After the metabolism trial blood was collected from intact animals to estimate the nitrogen constituents in blood serum of animals fed on different sources of energy. Results revealed no significant difference in the intake of UMMB in three groups. Similarly, the intake of DM (kg), DCP (g) and TDN (kg) per day was similar in three groups statistically. The apparent digestibility of dry matter (DM), organic matter (OM), ether extract (EE) and nitrogen free extract (NFE) was significantly (p<0.05) more in group II than group III, whereas the digestibility of DM, OM and NFE was similar in group I and II. The digestibility of crude fiber (CF) and all the fiber fractions i.e. NDF, ADF, cellulose and hemicellulose was alike in 3 groups. Nitrogen balance (g/d) was significantly (p<0.05) more in group III as compared to group I and II, which were alike statistically, though the N intake (g/d) was similar in 3 groups but N balance (g/d) was significantly (p<0.05) less in group III as compared to other 2 groups. Significantly (p<0.05) higher concentration of total volatile fatty acids (TVFA), total nitrogen (TN) and its fractions were observed in group I and II as compared to group III. There was no effect on rumen pH, rumen volume and digesta flow rate due to different sources of energy in 3 groups. Similarly the blood serum biochemical parameters (NH3-N, urea-N and total protein) were statistically identical in 3 groups.

Objectives The relationship between metabolic syndrome causes and bone mineral density (BMD) was explored by taking 60 female chronic low back pain patients with age 61 years old or elder having metabolic syndrome and osteoporosis as study subjects. Methods Fasting blood glucose, serum total-cholesterol, triglyceride and HDL were measured by biochemical tests. Anthropometric elements and blood pressure were measured. Results Average BMD and T-score of part number 1 to 3 of lumbar vertebra were estimated by Quantitative Computed Tomography (QCT). In order to find the relationship between clinical factors and osteoporosis, correlation analysis was done on T-score. Age (r=0.679, p<0.01) had significant negative correlation and weight (r=0.342, p<0.01) and height (r=0.475, p<0.01) had significant positive correlation. Blood glucose, blood pressure, total cholesterol, triglyceride, HDL and body mass index did not have significant correlation. BMD had negative correlation with age (r=0.317, p<0.05). Regression analysis was done by taking T-score as independent variables and taking other factors as dependent variables. It was possible to know that age ($\beta$=-0.471, t=-7.050) with p<0.001, height ($\beta$=0.277, t=4.120) and weight ($\beta$=2.856, t=2.780) with p<0.05 have significant impact on osteoporosis. Conclusions Therefore, it was possible to know that T-score and BMD decrease as one gets older and T-score and BMD increase as one is taller and heavier.

Status of blood minerals and their absorption by neonate calves as influenced by fat soluble vitamins supplementation in their respective mothers, mineral supplementation in calves themselves has been evaluated. The objective was to know the impact of antioxidant vitamin supplementation to advance pregnant buffaloes, on enhanced acquired immunity during first few hours after birth, in relation to weight gain in buffalo calves. Advance pregnant buffaloes (n = 30) consisting of average body weight of $550{\pm}15$ kg and of 4-6 parity were fed on 25 kg green (green Jawar-Sorghum bicolor), 2-3 kg wheat straw and 3-4 kg concentrate mixture individually per day. Intramuscular injections of vitamin triplex A $D_3$ E consisting of -2,500,000 IU of vit A -Palmitate; 2,500,000 IU of vitamin $D_3$ and 1,000 IU of vit E (dl-alpha tocopherol acetate) were given per dose, a month prior to parturition, twice at 15 days interval to 15 dams. Rest of the 15 pregnant buffaloes served as negative controls. Secretion of immune proteins, immunoglobulin (Ig) enhanced by 80% in colostrum. The blood serum levels of Zn, Cu, Ca, Mg were measured from birth to 90 days in calves. A significant (p<0.05) difference between the blood serum Zn levels of calves born to vitamin supplemented and non-supplemented dams was measured and a positive correlation between blood serum Zn levels and injections of vitamins was identified. Association of Zn and Cu with passive immunity status has been identified in these calves. A significant positive correlation between Zn and Cu was also identified which showed a change under the impact of vitamin supplementation in buffaloes. The study signifies the role of micronutrients supplementation in dams prior to parturition, in calf immunity development. The study indicates significant mineral - vitamins interactions during this process.

The purpose of this study was to Investigate the effects of green tea catechin on changes of mineral contents in chronic cadmium-poisoned rats. Sprague-Dawley male rats weighing 100 $\pm$ 10g were randomly assigned one of normal group and three cadmium poisoned groups. Cadmium groups were classified to catechin free diet(Cd-0C group), 0.25% catechin diet(Cd-0.25C group) and 0.5% catechin diet(Cd-0.5C group) according to the levels of catechin supplement. Animals were raised for 20 weeks. Cadmium was supplied in drinking water which contained 50ppm Cd$^{2+}$. Effects of catechin were analyzed on changes of mineral contents in chronic cadmium poisoned rats by determining the calcium accumulation in bones, blood, urine and faces and phosphorus In blood and urine. Cd-poisoning inducted the decrease of red blood cell(RBC), white blood cell(WBC), contents of blood hemoglobin and hematocrit, but the levels of those indices were increased by catechin supplementation. The contents of tibia and femur in Cd-0C group was significantly lower than in normal group, but those of catechin supplemetation group was similar to normal group. The calcium contents of urine and faces were higher in Cd-poisoned groups than in normal group, but they was lowered by catechin supplementation. The phosphorus contents of blood and urine in Cd-0C group was significantly lower than in normal group, but that of catechin supplementation group was similar to normal group. Catechin supplementation improved the calcium metabolism in chronic cadmium poisoned rats by increasing the contents of minerals such as calcium and phosphorus in blood and femur and by lowering the urinary and fecal calcium.m.

Purpose: Patients with chronic gastrointestinal disease are at risk for trace element deficiency due to impaired absorption and gastrointestinal loss. The aim of this study was to evaluate the trace element status of patients with gastrointestinal disease by blood and hair analysis, and to determine the usefulness of hair mineral analysis for diagnosing trace element deficiency not detected by a blood test. Methods: An analysis of hair minerals was performed and compared with blood mineral analysis in 13 patients with chronic gastrointestinal disease. The concentration of each element in the hair and blood was compared in the subgroups based on parenteral nutritional support or clinical symptoms. Results: Almost all patients had trace element deficiency. The trace elements deficient in the blood or hair analysis included zinc, selenium and copper. The hair zinc concentration was significantly lower in the group receiving parenteral nutritional support. The hair selenium concentration was statistically associated with the clinical symptoms of hair loss, brittle hair and loss of hair pigmentation. Conclusion: The results of this study suggest that patients with chronic gastrointestinal disease should receive adequate zinc and selenium replacement to avoid trace element deficiency especially when treated with long-term parenteral nutrition. Hair mineral analysis is useful as a complementary tool for the detection of a trace element deficiency.
