The Comparative Study

Previously it has been shown that cell hydration is a universal and extrasensitive marker for different environmental mediums and functional state of tissue and organism. The comparative study of cell hydration of different organs (brain cortex, liver, and skeletal muscle) at various experimental conditions (microstress, pathology, and different poisons) was realized. It was shown that among tissues of different organs muscle hydration is more sensitive to any change of functional state of organism and environmental medium. The study of correlation between tissue muscle hydration and double-frequency measurement impedance method indicated that the differences between muscle reactive conductivity measured at high frequency (HF) and low frequency (LF) could be an adequate marker for detection of muscle hydration. The animal poisoning, stress, and pathology-induced tissue hydration were accompanied by increase in . The observed close correlation between time-dependent tissue hydration and in different environmental mediums can be a marker for detection of postmortal period as well as for characterizing environmental medium of the corpse.

Abstract. Detection of T4 and T3 in paraffin sections of the rat thyroid gland in various functional states was attempted by an immunoenzyme technique. Both hormones showed a similar localization, being detected mainly in the colloid in the follicular lumen, and sometimes in certain regions of the cytoplasm of the follicular epithelium. Following administration of TSH, their stainability was increased, and the localization within the cytoplasm became more remarkable. Decrease or disappearance of stainability was observed after hypophysectomy or administration of PTU. These findings support the view that the immunostainability of T4 and T3 is closely correlated with the functional state of the thyroid gland.

Specimen Edge

During the course of electron transmission investigations of the deformation structures associated with shock-loaded thin foil specimens of 70/30 brass, it was observed that in a number of instances preferential etching occurred along grain boundaries; and that the degree of etching appeared to depend upon the various experimental conditions prevailing during electropolishing. These included the electrolyte composition, the average current density, and the temperature in the vicinity of the specimen. In the specific case of 70/30 brass shock-loaded at pressures in the range 200-400 kilobars, the predominant mode of deformation was observed to be twin-type faults which in several cases exhibited preferential etching similar to that observed along grain boundaries. A novel feature of this particular phenomenon was that in certain cases, especially for twins located in the vicinity of the specimen edge, the etching or preferential electropolishing literally isolated these structures from the matrix.

Toxic Injury

The increased number of lysosomes as well as the close approximation of lysosomes to the Golgi apparatus in tissue under variety of experimental conditions is commonly observed. These observations suggest Golgi involvement in lysosomal production. The role of the Golgi apparatus in the production of lysosomes in mouse liver was studied by electron microscopy of liver following toxic injury by CCI4.

Incident Beam Energy

The ultimate sensitivity of microchemical analysis using x-ray emission rests in selecting those experimental conditions which will maximize the measured peak-to-background (P/B) ratio. This paper presents the results of calculations aimed at determining the influence of incident beam energy, detector/specimen geometry and specimen composition on the P/B ratio for ideally thin samples (i.e., the effects of scattering and absorption are considered negligible). As such it is assumed that the complications resulting from system peaks, bremsstrahlung fluorescence, electron tails and specimen contamination have been eliminated and that one needs only to consider the physics of the generation/emission process.The number of characteristic x-ray photons (Ip) emitted from a thin foil of thickness dt into the solid angle dΩ is given by the well-known equation
