The procedure of restorative proctocolectomy is associated with a complete removal of the colon and slight reduction of ileum length, which together can lead to systemic shortages of trace elements. Inflammatory changes in the pouch mucosa may also have some impact. However, there is no data on trace elements in pouchitis. Therefore, in the present study we aimed to assess the effect of acute pouchitis on the status of selected trace elements in rats. Restorative proctocolectomy with the construction of intestinal J-pouch was performed in twenty-four Wistar rats. Three weeks after the surgery, pouchitis was induced. Eight untreated rats created the control group. Liver concentrations of selected micronutrients (Zn, Cu, Co, Mn, Se) were measured in both groups six weeks later, using inductively coupled plasma mass spectrometry. Liver concentrations of trace elements did not differ between the study and the control groups. However, copper, cobalt and selenium concentrations [μg/g] were statistically lower (p

Background: Several trace elements have been implicated in the etiology of type 2 diabetes, they can influence the onset or pathogenesis of diabetes in various ways including disruption of normal metabolism of glucose and insulin. The purpose of this work is to evaluate the serum status of copper, zinc, selenium, chromium and manganese in Moroccan type 2 diabetics compared to control group.Methods: Blood samples from 100 type 2 diabetics and 90 control subjects were analyzed for blood glucose, glycated hemoglobin (only for diabetics), lipid status and serum trace elements concentrations.Results: Glucose and triglyceride values were statistically higher in diabetics; while those of HDL-cholesterol were lower. Concentrations of zinc, selenium, chromium, and manganese were lower in diabetics compared to controls. In contrast, copper concentrations were higher.Conclusions: The status of trace elements is impaired in type 2 diabetics compared to a control group.

Background: The objective of the present study was to determine concentrations of zinc (Zn), copper (Cu), iron (Fe), selenium (Se) in blood plasma and manganese (Mn) in the whole blood in patients with long-term home parenteral nutrition (HPN) in comparison to the control group. Patients and Methods: We examined 68 patients (16 men and 52 women) aged from 28 to 68 years on a long-term HPN lasting from 4 to 96 months. The short bowel syndrome was an indication for HPN. The daily doses of Zn, Cu, Fe, Se and Mn in the last 3 months were determined. Results: No significant differences in blood plasma were found for Zn, Cu and Fe in patients with HPN and in the control group (p > 0.05). The concentration of Mn in whole blood was significantly increased in HPN patients (p < 0.0001), while Se concentration in these patients was significantly decreased (p < 0.005). The concentration of Mn in the whole blood of 16 patients with cholestasis was significantly increased compared to the patients without cholestasis (p < 0.001). The Cu concentration was increased with no statistical significance. Conclusion: In long-term HPN, the status of trace elements in the patients has to be continually monitored and the daily substitution doses of these elements have to be flexibly adjusted. Dosing schedule needs to be adjusted especially in cases of cholestatic hepatopathy. A discussion about the optimal daily dose of Mn in patients on HPN is appropriate. For clinical practice, the availability of a substitution mixture of trace elements lacking Mn would be advantageous.

Abstract The objective of the study is multi elemental analysis of four indigenous Ethiopian tuber crops using instrumental neutron activation analysis (INAA) technique in order to get scientific evidences about the status of essential, trace and non-essential elemental compositions. The samples were collected from Southern and South-western parts of Ethiopia. The irradiation and measurement were performed by using irradiation and counting facilities of the Nigeria Nuclear Reactor-1 (NIRR-1) and a HPGe detector setup at the Centre for Energy Research and Training (CERT), Ahmadu Bello University (ABU), Zaria, Nigeria. A total of 17 elements were determined at various concentration levels. The highest concentrations of K, Mg, Mn and Zn were found in Colocasia esculenta (L.) Schott, whereas; the concentrations of essential and trace elements; Ca, K, Mg, Na, Cl, Mn, and Zn were found to be high in the native Coccinia abyssinica (Lam.) Cogn tuber. The estimated daily intake values of the constituent elements from the consumption of these crops are below upper tolerable limits set by international organizations such as WHO and FAO.

SummaryThe principal objective pursued in this study is to establish the base-line data on the status of elemental composition in human milk from Pakistani subjects of Rawalpindi/Islamabad area. Radiochemical neutron activation analysis (RNAA) methodology was developed and successfully employed to determine the concentration of 18 minor and trace elements (essential, toxic and nonessential) in human milk. This methodology has significantly improved the detection limits of most of these elements due to suppression of Compton background. The data provide the base-line values of these elements in human milk of low- and medium-income group subjects of the region. The results obtained show good compatibility with the data reported by the WHO on elemental composition of human milk from different geological regions.

The Status

This study aimed at investigating the status of non-enzymatic antioxidant agents during experimental caprine coccidiosis. A total of 20 newborn kids were selected and allocated into 2 (diseased and healthy) groups. Ten of the kids were infected with sporulated oocysts of the most pathogenic species of <em>Eimeria</em> and ten served as controls. Blood samples were taken at 0 (before inoculation), 3, 7, 14, 21, 28 and 35 days post infection (dpi) and the concentrations of antioxidant trace elements, antioxidant vitamins and ceruloplasmin were measured. Our data showed remarkable reductions in serum concentrations of some antioxidant trace elements (zinc, manganese and selenium) and vitamins (vitamin C) in the diseased kids, however, significant increases were observed in the serum level of ceruloplasmin in infected animals. These alterations became more prominent at 14 to 21 dpi. These observations suggest that <em>Eimeria</em> parasites can significantly interfere with the levels of some antioxidant trace elements and vitamins during caprine coccidiosis. These changes indicate the overproduction of oxidative radicals during the pathogenesis of <em>Eimeria</em> species that may account for extensive oxidative damage in infected animals.

Macro elements are the minerals of which the body needs more amounts and are more important than any other elements. Trace elements constitute a minute part of the living tissues and have various metabolic characteristics and functions. Trace elements participate in tissue and cellular and subcellular functions; these include immune regulation by humoral and cellular mechanisms, nerve conduction, muscle contractions, membrane potential regulations, and mitochondrial activity and enzyme reactions. The status of micronutrients such as iron and vanadium is higher in type 2 diabetes. The calcium, magnesium, sodium, chromium, cobalt, iodine, iron, selenium, manganese, and zinc seem to be low in type 2 diabetes while elements such as potassium and copper have no effect. In this review, we emphasized the status of macro and trace elements in type 2 diabetes and its advantages or disadvantages; this helps to understand the mechanism, progression, and prevention of type 2 diabetes due to the lack and deficiency of different macro and trace elements.
