From a rock to a hard place: Journeys of a radiochemist through inner and outer space

A brief chronicle is presented of one radiochemist's meanders through the fields of meteoritics, lunar studies, and geochemistry to current studies of possible relationships of trace element imbalances to diseases affecting the brain and spinal cord. This range of studies is used to underscore the broad applications of radiochemistry and the need to maintain educational programs and research in radiochemistry. Our recent studies of tissues from subjects with Alzheimer's disease (AD) and amyotrophic lateral sclerosis (ALS), have shown that imbalances exist for concentrations of many trace elements, compared to corresponding concentrations in control subjects. Among the elements most frequently found imbalanced are aluminum, bromine, cadmium, copper, iron, mercury, rubidium, and zinc. Several of these elements may be involved in processes leading to free-radical-induced oxidative damage in Alzheimer's disease. Our multi-technique analytical approach to these studies is briefly reviewed.     

Activation analysis in a multitechnique study of trace element imbalances in age-related neurological diseases

It has been suggested that several age-related neurological diseases such as Alzheimer's disease and amyotrophic lateral sclerosis may be related to environmental toxins. Bulk sample multielement analyses by INAA alone are not adequate to define the role of trace elements in these diseases. A multitechnique approach has been developed that incorporates 14 MeV, instrumental reactor, radiochemical, and pre-irradiation chemical neutron activation analysis, together with laser microprobe mass spectrometry. The analytical scheme is able to provide bulk or protein normalized elemental concentrations, as well as microstructural, cellular, and subcellular localization information.     

Determination of trace elements in blood samples of patients affected by multiple sclerosis from Iran by neutron activation analysis

Multiple sclerosis (MS) is a neurological autoimmune disease in which the immune system attacks the central nervous system for unknown reasons and causes several damages to human body by demyelinating the nerve cells. One of the possible cause of this disease is the abnormality levels of some trace elements such as Br, Fe, Rb, Sb, As, and Zn in human body. This study attempts to measure the levels of four trace elements of Br, Fe, Rb, and Zn in the patients?? blood samples and compare them with control samples from healthy individuals. It should be noted that the objectives set out partly met. According to the obtained results, the differences between the levels of Br, Fe, and Rb in patients?? blood samples and control was not significant (P?>?0.05). However, the average level of Zn between samples and controls showed a significant difference (P?<?0.05). Therefore the lower level of Zn in blood is likely to be a major cause of MS emergence. Furthermore, by using the concentration level of Zn as indicator, it was revealed that the risk of MS infection rises as the number of pregnancies increase.

Determination of trace elements in drinking tea by various analytical techniques

Tea has been one of the most popular simulating beverages which is both heavily produced and consumed in Taiwan. The determination of minor or trace elements in drinking tea and tea leaves is therefore important for estimating the daily intake of Taiwanese considered as a safety indicator. In order to accurately and precisely determine the concentrations of trace elements in samples, several analytical methods such as AAS, NAA and ICP-AES are suggested. This paper attempts to utilize all three methods to determine the concentrations of minor or trace elements in different types of tea leaves and the extracts percolated from them. The influence of fermentation processes on the concentration levels of minor or trace elements in tea samples is investigated. Because only free metal ions are bioavailable for the human body, it is necessary to determine their concentrations in drinking tea. The dissolution of trace elements in drinking tea is therefore studied by simulating the common Chinese style of tea percolation. Concentrations of thirteen elements including Zn, Mn, Ca, Cu, Ni, Al, K, Mg, Cd, Pb, Na, Co and Sc are determined.     

缺锌儿童的舌苔改变及其分析

从中医舌诊角度对193例缺锌儿童舌苔改变作了临床观察及理论分析,认为人体内微量元素锌与舌苔之间存在着有机联系,锌的吸收障碍由脾、胃功能失司引起,相应地引起舌苔的改变,大多数表现为“地图舌”。发现“地图舌”患儿在其他临床症状方面与机体“缺锌”状态表现出来的症状相似,而且病因相同,在病理机制及组织学方面曲解释一致,且用“锌”制剂治疗后,“地图舌”明显很快地消失或得到改变。笔者提出,“地图舌”可以作为机体缺锌的临床体征之一,本文为此提供了初步的理论依据。
