Aim To assess serum HGF concentration in individuals with bipolar disorder and investigate the efficacy of zinc therapy on these levels. Subjects and Methods Serum from 35 individuals diagnosed with bipolar disorder and 19 age and gender similar controls were tested for HGF concentration using ELISAs, and copper and zinc plasma levels using inductively-coupled plasma-mass spectrometry. Results HGF serum levels of individuals with bipolar disorder were significantly lower than age and gender similar controls ( P = 0.0021). HGF serum concentration was significantly lower in Bipolar patients pre-therapy ( P = 0.0009) and HGF levels normalized post-therapy. Zinc levels in these same individuals also normalized ( P = 0.0046) and patient's perceived severity of Bipolar symptoms significantly decreased after therapy ( P = 0.0003). We also found a significant direct correlation between Zinc and HGF serum concentration in the bipolar patients ( P = 0.04). Discussion These results suggest an association between low HGF levels and bipolar disorder and also demonstrate that zinc therapy may be associated with the normalization of HGF levels and decrease in severity of disease.

Aim To assess serum HGF concentration in individuals with schizophrenia and investigate the efficacy of zinc and B-6 therapy on these levels. Subjects and methods Serum from 18 individuals diagnosed with schizophrenia and 19 age and gender similar controls ( P = 0.18) were tested for HGF concentration using ELISAs, and tested for copper and zinc plasma levels using inductively-coupled plasma-mass spectrometry. Results HGF serum levels of individuals with schizophrenia, before zinc and B-6 therapy, were significantly lower than age and gender similar controls ( P = 0.016), and significantly lower in schizophrenia patients pre-therapy compared to post therapy ( P = 0.028). HGF levels normalized (reached levels similar to controls) post-therapy. Zinc levels in these same individuals also normalized, and perceived symptoms, particularly anxiety ( P = 0.03), improved significantly after therapy. Discussion These results suggest an association between low HGF levels and schizophrenia and demonstrate that zinc and B-6 therapy may be associated with the normalization of HGF levels and perceived improvement in symptoms.

Abstract Background Several researches have been conducted on the associations between elements and diseases. Few studies have examined trace elements in young people’s hair. The objective of this study is to investigate the influence of age, gender and season on the contents of magnesium (Mg), calcium (Ca), Iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), selenium (Se) and strontium (Sr) as well as to establish the reference intervals (RIs). Methods We conducted a retrospective study of 589 apparently healthy children and adolescents under 19 years old. Quantitative analysis has been carried out using inductively coupled plasma-mass spectrometry (ICP-MS). Eight nutrient elements in peripheral blood of children and adolescents in eastern China were grouped according to age, sex or season, and analyzed using and Mann-Whitney U test and spearman statistical analyses. RIs were defined by using 95% confidence interval. Results Precisions of ICP-MS detecting for Mg, Ca, Fe, Cu, Zn, Mn, Se and Sr are 2.8%~12.2%. The linearity were all > 0.999 and the bias were all within 10%. Differences between contents of particularly Mg, Fe, Cu and Zn in girls’ and boys’ whole blood were found, and higher contents of Mg, Cu for boys were measured in some age groups. Positive correlations for Fe, Zn, Se and Sr, while negative for Ca and Cu were found with age. And substantial differences between age groups were stated. In general, an increasing trend was found for bioelements (Fe, Zn,Se) both for girls and boys in all age groups, while for Ca and Cu changes were even decreasing for children and teenagers. The most frequently correlating element pairs were Fe-Zn, Mg-Se, and Fe-Se in five successive age groups. Lower contents of essential elements (Mg, Ca, Fe, Zn, Se) were found in summer comparing with other seasons. Finally, the reference interval of each element was initially established according to age and gender grouping. Conclusions The contents of elements in whole blood varies depending mainly on the gender and age of children and adolescents. Besides, season is also a factor that affects the contents of elements in the body. The reference intervals of elements in whole blood grouped by age and gender provide a reference basis for clinical diagnosis and treatment of element-related diseases.

Aim To assess serum Cu/Zn SOD (Superoxide Dismutase) concentration in individuals with clinical depression. Subjects and Methods Serum from 36 individuals diagnosed with clinical depression and 18 healthy controls were tested for Cu/Zn SOD serum concentration using ELISAs. Results Serum Cu/Zn SOD levels of depressed individuals (both with and without secondary anxiety) were significantly higher than age and gender similar controls. We also found that, post anti-oxidant therapy, Cu/Zn SOD levels normalized to the level of normal healthy controls. Discussion These results suggest an association between Cu/Zn SOD serum levels and clinical depression.

The aim of this study was to determine if altered levels of selected trace elements manifest themselves during chronic depression. To identify elements strongly associated with chronic depression, relationships between the elemental contents of hair and nails and the interelement correlations were checked. Inductively coupled plasma mass spectrometry and ion chromatography were used to evaluate the contents of Zn, Cu, Co, Pb, Mn, and Fe in hair and nail samples from a total of 415 subjects (295 patients and 120 healthy volunteers). The study included logistic regression models to predict the probability of chronic depression. To investigate possible intercorrelations among the studied elements, the scaled principal component analysis was used. The research has revealed differences in TE levels in the group of depressed men and women in comparison to the healthy subjects. Statistically significant differences in both hair and nails contents of several elements were observed. Our study also provides strong evidence that the intermediary metabolism of certain elements is age- and gender-dependent. Zn, Mn, Pb, and Fe contents in hair/nails seem to be strongly associated with chronic depression. We found no statistically significant residence-related differences in the contents of studied elements in nonoccupationally exposed patients and healthy subjects.

Aim To assess plasma zinc and copper concentration in individuals with autism. Subjects and Methods Plasma from 79 autistic individuals, and 18 age and gender similar neurotypical controls, were tested for plasma zinc and copper using inductively-coupled plasma-mass spectrometry. Results Autistic individuals had significantly elevated plasma levels of copper and Cu/Zn and lower, but not significantly lower, plasma Zn compared to neurotypical controls. Zn levels increased significantly in autistic individuals with and without GI disease after zinc therapy. Cu decreased significantly after zinc therapy in the GI disease group but not in the autistic group without GI disease. Autistic children significantly improved with respect to hyperactivity and stimming after zinc therapy in autistic children with GI disease. Autistic children without GI disease did not improve in these symptoms after the same therapy. Discussion These results suggest an association between zinc and copper plasma levels and autism, and they suggest that zinc therapy may be most effective at lowering copper levels in autistic children with GI disease.

Abstract Background Trace elements are assumed to be involved in glaucoma pathogenesis via changes in oxidative stress. Especially serum selenium (Se) has been linked to this neurodegenerative disease. Serum Se levels differ between countries due to nutrition and ethnicity. It was the aim of the present study to investigate serum Se levels in primary open-angle glaucoma (POAG) patients and controls in Germany and to consider potential age and gender effects. Material and Methods The Se concentration of 39 serum samples (22 patients with POAG, 17 controls) were analyzed by inductively coupled plasma-sector field mass spectrometry (ICP-sf-MS) in high resolution mode. Covariance and percentile regression were analyzed. Age and gender were defined as confounding factors and their different trends were investigated. Moreover, age was examined across different quantiles of Se levels. Results Total serum least-squares means (LS-means) Se levels were 132.02 µg/L (controls) and 134.86 µg/L (POAG). Total serum Se levels did not differ between the study groups (p > 0.05). Significant age and gender effects of serum Se were observed. Quantile analysis showed that the 1st serum Se quantile decreased with increasing age in POAG patients in contrast to controls. The odds ratios of the 1st serum Se were 1.3 (with 2nd quantile) and 1.3 (with 3rd quantile), respectively. Conclusion The serum Se level of the German cohort was almost half of those of the published US cohort (glaucoma 209.11 ng/mL; control 194.45 ng/mL). Age and gender effects were observed; the serum Se level increased with age in women (controls and POAG), however, Se levels decreased with age in men (controls and POAG).

AbstractThis study investigated lead concentrations in the hairs of radiographers working in the radiological departments of general hospitals that used lead shielding for radiation protection. We collected scalp hair samples from 32 radiographers working in four radiology departments with lead shielding and 18 administration personnel in the same hospitals without lead shielding. Samples were analyzed for lead concentrations by inductively coupled plasma mass spectrometry. As a result, lead concentrations in the hairs of the radiological technologists were significantly higher than those in the administration staffs (0.72 ± 0.51 vs. 0.19 ± 0.27 μg/g, P < 0.001). The hair lead concentrations were positively and significantly associated with environmental lead concentrations (r = 0.6, P = 0.001), but not associated with age, working duration, and gender distribution.
