ABSTRACT
The elemental analysis of packed food items which is collected in Debre Tabor markets, Ethiopia namely Pasta, Macaroni, cookies, biscuit, wheat bread, white teff injera, Red teff injera, barley so, barleycorn and maiz bread samples were carried out using EDX spectrometer. An X-ray beam was used to excite each sample and spectra were recorded with a high-resolution Si(Li) detector. The data analysis was carried out by software. Trace elements P, K, Na, Cl, Mg, Ca, Fe, Al and Zn were estimated, and elemental concentrations were determined. To get the exact results of the present study the analysis repeats three times.
ABSTRACT
The relative protective efficacy of oral administration of mycobacteria as compared to the conventional intradermal route of vaccination has been assessed in guinea pigs. Skin test reactivity to partially purified protein derivative and protective immunity to challenge with virulent Mycobacterium tuberculosis were used as parameters of protective immunity. Oral immunisation of guinea pigs either with BCG or with Mycobacterium avium intracellulare induces skin test reactivity and protective immunity comparable to that induced by intradermal route of vaccination. Oral exposure of Mycobacterium avium intracellulare prior to oral or intradermal dose of BCG did not interfere with the protective immunity induced by BCG in guinea pigs challenged with Mycobacterium tuberculosis H37Rv.
