SKIN CONDITION IN EXPERIMENTAL INFECTION OF SHEEP WITH CONTAGIOUS DERMATITIS

As a result of the study, it was found that with contagious pustular dermatitis, the damage affects the epidermis and dermis of the skin. The most severe damage is recorded in the epidermis on day 9, fragments of organelles and viroplast clusters are observed in the cytoplasm. On the 22nd day, regenerative and regenerative processes prevail in the epidermis and dermis, in the form of proliferation, cell differentiation and organization of intercellular substance.

The Impact

Introduction: Aging facial skin is a natural and unavoidable process. It involves a gradual weakening of the biological activity of cells, extension of regenerative processes and reduction of adaptability. At the same time, a smooth, radiant, wrinkle-free complexion has been a global trend in cosmetology for many years, which results in more and more people, especially women, benefiting from new non-invasive anti-aging treatments. One of such treatments offered on the cosmetology market are treatments utilising RF radio waves. Therefore, the aim of this study was to assess the impact of a series of treatments utilising RF on the skin of the faces of women. Materials and methods: The analysis of the results was carried out by the examined person and by the authors of the project via a point scale of visual assessment of skin condition. The following facial skin parameters were analysed in the study: depth of wrinkles, elasticity, skin brightening and moisturising. Results and conclusions: The conducted own study proves the impact of treatments using RF radio waves on the skin of the face. The applied series of treatments caused a partial reduction of the most visible and deepest wrinkles, as well as improved elasticity, brightening and moisturising of the facial skin.

Infected Chimpanzee

Experimental infection of chimpanzees with non-A, non-B hepatitis (NANB) or with delta agent hepatitis results in the appearance of characteristic cytoplasmic alterations in the hepatocytes. These alterations include spongelike inclusions (Type I), attached convoluted membranes (Type II), tubular structures (Type III), and microtubular aggregates (Type IV) (Fig. 1). Type I, II and III structures are, by association, believed to be derived from endoplasmic reticulum and may be morphogenetically related. Type IV structures are generally observed free in the cytoplasm but sometimes in the vicinity of type III structures. It is not known whether these structures are somehow involved in the replication and/or assembly of the putative NANB virus or whether they are simply nonspecific responses to cellular injury. When treated with uranyl acetate, type I, II and III structures stain intensely as if they might contain nucleic acids. If these structures do correspond to intermediates in the replication of a virus, one might expect them to contain DNA or RNA and the present study was undertaken to explore this possibility.

Histopathological Findings

It has been shown in previous studies that the toxin T-514 isolated from K. humboldtiana induces severe damage to the lung in treated rodents. Histopathological findings include edema, and alveolar hemorrage. However, the ultraestructure of the lesion has not been investigated. In this study we used two species of rodents: Hamster and guinea pig, and a primate: Macaca fascicularis. Animals received different single dosis of the toxin via intraperitoneal. Control animals received only the vehicle (propylen glycol). Inmediately after spontaneous death, lung samples were fixed in Karnovsky-Ito fixative, post fixed in osmium tetroxide and embedded in epon. Thin sections were prepared with an Ultratome V LKB, stained with uranly acetate and lead citrate, and studied in an electron microscope Zeiss-EM109.

Thymic Factor

The possibility that intrathymic T-cell differentiation involves stem cell-lymphoid interactions in embryos led us to study the ultrastructure of epithelial cell in normal embryonic thymus. Studies in adult thymus showed that it produces several peptides that induce T-cell differentiation. Several of them have been chemically characterized, such as thymosin α 1, thymopoietin, thymic humoral factor or the serum thymic factor. It was suggested that most of these factors are secreted by populations of A and B-epithelial cells.Embryonic materials were obtained from inbred matings of Swiss Albino mice. Thymuses were disected from embryos 17 days old and prepared for transmission electron microscopy. Our studies showed that embryonic thymus at this stage contains undifferentiated and differentiated epithelial cells, large lymphoblasts, medium and few small lymphocytes (Fig. 5). No differences were found between cortical and medullary epithelial cells, in contrast to the findings of Van Vliet et al,. Epithelial cells were mostly of the A-type with low electron density in both cytoplasm and nucleus. However few B-type with high electron density were also found (Fig. 7).
