Based on research conducted by the author in the last thirty-five years, this article presents the physicochemical mechanisms of the osteoporosis process, transport of substances created as its result, and the phenomena of tissue mineralization resulting from osteoporosis. Examination of bones, joint cartilage, arteries, veins, parts of heart, thyroid, salivary glands, various tumors and others was conducted with the use of biological and polarizing microscopy, SEM, EDS, ASA, IR, Raman spectroscopy, and X-ray diffraction. Several devices of the same kind, e.g. different types of SEM, were used. Specimens used for examination were obtained from post-surgery and post rnortem materials. Examination of human bones focused on their mineralization and demineralization (osteoporosis). Examination of the mineralization of other tissues was conducted in terms of the ageing of human body. Obtained results show that the process of osteoporosis leads not just to mechanical degradation of bones, but through the transport of ions (mainly Ca and P), it also causes mineralization of soft tissue. Such mineralization occurs in mineralization centers that have been classified in regard to genetics. Tissue mineralization in its first stage is latent and consists of including atoms, mainly Ca and P, into the biological structures of compounds that build the tissues. Latent mineralization may evolve into the next stage--apparent mineralization. Both types of mineralization cause many health issues and may lead to death. This article also presents initial results of research on dissolution of aortic mineralization. 展开更多

We examined the stability of amoxicillin trihydrate from the preparation Augmentin in compounded forms of drugs such as vaginal suppositories and ointments. The quantity of the antibiotic in the preparations studied was determined directly after they had been made and after a lapse of 7 and 14 days. We also carried out comparative examinations of the stability of sodium amoxicillin (Tarommentin) and sodium ampicillin (Ampicillin) in ointments with an addition of a boric acid solution. The examinations confirmed the stability of amoxicillin trihydrate in suppositories and in anhydrous and hydrated ointments. The content of this antibiotic in ointmems with an addition of a boric acid solution decreases slightly. Comparative studies of the stability of sodium amoxicillin and sodium amoxicillin revealed a markedly lower stability of the two antibiotics in comparison to the stability of amoxicillin trihydrate. 展开更多
