Food Intake Assessment, Measurement of Lithium and Magnesium Serum Levels, and TheirCorrelation with Aggression in the Residents of Ahvaz Jundishapur University of Medical Sciences’ Dorms in 2012

Background: This study was undertaken to investigate the changes in salivary and serum calcium and alkaline phosphatase in osteoporosis patients. The objective was to compare the change in serum levels with those in saliva.Methods: The study was conducted in the department of biochemistry, National Institute of Medical Sciences and Hospital, Shobha Nagar, Jaipur, Rajasthan, India. Subjects were selected from department of orthopedics, National Institute of Medical Sciences and Hospital, Shobha Nagar, Jaipur, Rajasthan, India. At the same time one hundred adult osteoporosis patients confirmed by DEXA were taken. Calcium and alkaline phosphatase were measured in serum and saliva of each patient. The data obtained was statistically analyzed.Results: Serum calcium has strong positive correlation with salivary calcium (r=0.726) while serum ALP and salivary ALP had weak positive correlation (r =0.453).Conclusions: Saliva can be used to measure calcium level instead of serum as it is non-invasive, quick and easy method.

Severe chronic metabolic acidosis (CMA) in rats is associated with poor food intake and downregulation of growth hormone (GH), insulin-like growth factors (IGFs), and liver receptors; the administration of recombinant GH (rGH) fails to improve the growth failure. In mice with carbonic anhydrase II deficiency (CAD), a model of moderate CMA with food intake close to normal, we studied serum levels of GH, IGFs, and IGF-binding proteins, and the growth response to rGH. CAD was associated with low serum levels of GH in males. Randomized administration of rGH from ∼5 to ∼12 wk to CAD mice improved food efficiency and increased serum IGF-I levels, final length, and weight compared with placebo without affecting blood pH. Although administration of rGH also increased linear growth in healthy animals, the effect was less than that in CAD mice and was only observed when started before 6 wk of life. Thus growth failure in CAD mice is associated with a decrease in GH secretion in males but not in females. Long-term administration of rGH increases linear growth in CAD mice despite persistent CMA.

Food intake, body weight, serum levels of triiodothyronine (T3) and free thyroxine (FT4), and metabolic rate were measured at intervals in Svalbard (SR) and Norwegian (NR) reindeer. From summer to winter food intake decreased 57 (SR) and 55% (NR), while body weight decreased 8.6 (SR) and 3.8% (NR). In SR T3 and FT4 changed seasonally, whereas this was only evident for T3 in NR. Resting (standing) metabolic rate (RMR) in winter was 1.55 (SR) and 2.05 W X kg-1 (NR), lower critical temperature (TLC) being -50 (SR) and -30 degrees C (NR). RMR in summer was 2.15 (SR) and 2.95 W X kg-1 (NR), TLC being -15 (SR) and 0 degrees C (NR). Seasonal changes in T3 and FT4 did not coincide with changes in food intake or RMR in either SR or NR. RMR did, however, correlate with food intake. This indicates that seasonal changes in RMR are due to the thermic effects of feeding and represent no physiological adaptation aimed at conservation of energy during winter.

Significant Difference

Background: The role of trace metals in Pathogenesis of Pre-eclampsia has received insufficient attention in Nigeria.Materials and Methods: We examined the effect of serum levels of some trace metals; selenium (Se), zinc (Zn), copper (Cu), cobalt (Co), and manganese (Mn) in the development of pre-eclampsia in Nigeria. Blood samples were collected from 59 pre-eclamptic, 150 normal pregnant and 122 non pregnant women. Serum Se, Zn, Cu, Co and Mn were determined by AAS.Results: Result shows significantly lower serum Se, Zn, Cu, Cu: Zn ratio, Co and Mn in pre-eclamptics compared to normal pregnant women (p<0.001). Comparison of normal pregnant women and controls showed non significant difference in the zinc level (P>0.05), significantly lower levels of serum Se, Co, Mn (p<0.00011, p=0.0022, p<0.0001 respectively) and significantly raised copper level (p<0.001) in normal pregnant women compared to controls. Serum Se, Zn, Co and Mn were significantly lower (p<0.001) while serum copper and Cu: Zn ratio were significantly higher (p<0.001) in pregnant women compared to controls. ANOVA shows significant progressive decreases in serum Se, Zn Co and Mn, from controls to normal pregnant women and pre-eclamptics (p<0.0001).Conclusion: Decreases in serum level of Se, Zn, Cu, Cu: Zn ratio, Co and Mn may play important role in the pathogenesis of pre-eclampsia.Asian Journal of Medical Sciences Vol. 7(3) 2016 78-83
