Aim: The study aimed to determine the peculiarities of the micro- and ultrastructural organization of the skin under conditions of a four-week administration of an opioid to experimental animals.
Materials and Methods: The study material included skin samples of white rats with injected vascular beds, histological preparations, and ultrathin skin
sections. The research methods involved injection techniques, histological analysis, electron microscopy, morphometric measurements, and statistical analysis.
Results: The results of the study revealed that after four weeks of nalbuphine administration to experimental animals, blood stasis was observed in the lumen of the capillaries and venules, along with perivascular edema and perivascular infiltrates consisting of neutrophils, lymphocytes, macrophages, and tissue basophils. The electron density of the nuclei and cytoplasm of the granular layer keratinocytes was reduced, keratinocytes in the stratum spinosum acquired a rounded shape, with some nuclei appearing shrunken and hyperchromatic, and their cytoplasm exhibiting vacuolization. In the reticular layer, thickened bundles of collagen fibers were observed, with localized swelling and fragmentation of the collagen fibers. Excessive formation of scales was noticed in the stratum corneum. The papillary layer of the dermis contained numerous mast cells and lymphocytes near blood vessels. The shape of sebaceous and sweat gland cells was altered, with swollen cytoplasm, and lymphohistiocytic infiltration was observed around them. A decrease (p<0.05) in the density of capillary loops in the subpapillary vascular plexus of the skin in the gluteal region of white rats after four weeks of nalbuphine administration, along with an increase (p>0.5) in the trophic activity index of the skin, confirms profound destructive changes in the vascular architecture of the skin.
Conclusions: Four weeks of nalbuphine administration induces irreversible pathological processes in all skin components.
The hair texture changes and hair loss are often the first symptoms of diseases of internal organs. The aim - to study the changes in hair structure, which are reflected in the quality and appearance of hair, to monitor structural changes in the hair and to evaluate the impact of diseases of internal organs in patients in order to improve therapy.Over the course of one year, 40 patients were examined who complained of excessive hair loss and 25 persons, which constituted a control group of apparently healthy people. To determine the structural changes in the root and shaft of the hair, macro- and microscopic examination was used, which was carried out on MBI-3 microscope with an AU-12 binocular attachment (600x magnification). During the examination, the root and the surface of the shaft were carefully examined for cracks or other damage. The pyruvate and pyruvate dehydrogenase tests and antithyroid antibody titer tests were used to detect latent diabetes and autoimmune thyroiditis.
Conclusion: The effect of using lotion and shampoo with dimethylsilanediol in comprehensive treatment was obtained starting from the second month of therapy, which was confirmed by microscopic examination of the hair: hair roots were covered with sheaths, a tile pattern was observed along the entire length of the hair shaft, there were no ridges or grooves. A complete structural restoration of the hair was observed in 70% of patients.
One of the important problems in modern dermatology is to improve treatment efficiency of acne being a common cause for cicatricial skin changes, loss of performance capability and social activity and negatively affects the psycho-emotional state of patients and their quality of life. The topicality of the disease is due to the high degree of its proliferation, chronic and recurrent course, and resistance to existing therapies.
Objective: to study the effect of low level laser radiation (LLLR) on pustular microflora in acne patients and to determine the reasonability of its application in the course of complex treatment of such patients.
Herpes simplex virus (HSV) can be not only a nosological disease, but also a secondary infection that can affect the severity of the course of other dermatoses. Timely diagnosis and correct therapy of the progression of psoriasis helps related specialists to prevent the occurrence of such diseases. Therefore, the goal of our research is a comprehensive examination of patients with psoriasis, especially with a severe and atypical clinical course of the disease, with the aim of detecting herpes infection and improving the effectiveness of treatment of such patients. The detected changes in indicators of both humoral and cellular immunity in patients with psoriasis are indirect evidence of the negative influence of provoking factors and accompanying pathology on the intensity of the immune response in their body, which in turn leads to the formation of immunodeficiency.
Nowadays dermatologist’s arsenal contains numerous pharmacological agents with high efficiency, but achieving the desired results in acne therapy is still not the easiest problem. The aim - to study the modern possibilities of medical and cosmetological correction of acne manifestations based on the analysis of foreign and domestic sources. We conducted a review with further analysis of foreign and domestic sources, domestic, European and American recommendations for the treatment of acne. Publications were searched through the National Center of Biotechnology Information, PubMed, StudMed and GoogleBooks resources.
