Trace Elements Status in Sera of Patients with Allergic Asthma

Background: Asthma is a multifactorial disease and its severity varies with the inflammatory grade. There are conflicting reports about the roles of trace elements in asthma. This study examined the effects of zinc (Zn), copper (Cu), and selenium (Se) concentrations in sera of patients with allergic asthma attending Ghaem Hospital, Mashhad, Iran. Methods: Forty-nine patients, aged 10 to 50 y...

Trace Elements

Trace elements occur in the human and animal body in milligrams per kilograms amount or less as against major elements which occur in gram per kg.essential elements are elements required for lifewhose deficient intake results in impairment of vital functions and only intake of physiologic amounts of the element can alleviate or prevent such a disturbance in function. Certain T.Es exists in the ...

Trace Elements in Clinker –

The trace element content of clinkers (and possibly of cements) can be used for the qualitative identification (i.e. manufacturing factory). Several hundred clinker sorts have been analysed (by replicated quarterly samples, collected from all Hungarian cement factories as well as from factories of 8 foreign countries) to determine their Mg, Sr, Ba, Mn, Ti, Zr, Zn and V content. The first 6 elem...
