Histohemijska, imunohistohemijska i morfometrijska analiza promena na srčanom mišiću kod heroinskih zavisnika

In order to clarify the mechanism of heroin addicts death, besides changes in the lungs, which were most frequently studied, changes in the heart muscle were also observed. The weakening of the contractility of the myocardium and the binding of the connective tissue in the heart muscle are considered to be the basis for the development of possible pathogenetic mechanisms of dying. In order to define micro-morphological changes on the myocardium, histochemical, immunohistochemical and morphometric analysis determines the qualitative characteristics of cardiomyocytes and connective tissue, as well as the number of inflammatory cells in the myocardium (leucocytes, monocytes and macrophages, Tlymphocytes and mastocytes) of 42 cadavers whose death is in relation to the heroin abuse, and 10 cadavers from the control group. The quantification of these parameters was performed by measuring the thickness of the myocardiocyte and determining the percentage of connective tissue representation, and counting specific cell types in 30 visual fields in each of the 6 myocardial samples taken from the defined sites. The mean values were analyzed statistically. The connective tissue was statistically significantly present in the heroin addicts myocard in relation to the control group (p = 0.001). Cardiomyocytes were statistically significantly thicker in heroine addicts for p = 0.005. The number of leukocyte was significantly lower in the left ventricle compared to the right ventricle and the intraventricular septum (p = 0.02) for heroin addicts. Statistically significant differences between the sexes and between the groups defined by the length of heroin use were not recorded for the analyzed parameters. Cardiomyocyte hypertrophy, presence of connective tissue, and the presence of certain immune response cells indicate that prolonged use of the herion over time can lead to dysfunction of the heart muscle and heartbeat system, which may represent the cause of the death of heroin addicts

Oral rehabilitation of a patient with systemic lupus erythematosus using implant-supported fixed dentures: A case report with review of important considerations

Introduction. Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease with a variety of oral manifestations (dry mouth, reduced salivary flow, painful mucosal lesions and restricted mouth opening, impaired oral hygiene maintenance), as well as possible far-reaching systemic implications. In the context of SLE, oral rehabilitation with dental implants might be the most appropriate solution. However, a lack of available literature, as well as the absence of treatment protocols, often leads to unsatisfactory management of these patients. The aim of this paper was to describe oral rehabilitation of a patient with SLE using dental implants and fixed dentures in both jaws. Case outline. A 66-year-old female patient, who had suffered from SLE for over 30 years, was referred for oral rehabilitation as her chief complaints related to the existing mobile partial dentures in the jaws and poor chewing ability. Proposed oral rehabilitation with fixed dentures supported by six dental implants in the maxilla and four dental implants in the mandible, as well as prosthetic restoration of the mandibular teeth, was accepted by the patient. During the follow-up period of three years, no biological complications were observed related to the performed treatment. Conclusion. Dental implants might be the most suitable treatment modality for oral rehabilitation of patients suffering from SLE

Bioremediation of soil polluted with crude oil and its derivatives: Microorganisms, degradation pathways, technologies

The contamination of soil and water with petroleum and its products occurs due to accidental spills during exploitation, transport, processing, storing and use. In order to control the environmental risks caused by petroleum products a variety of techniques based on physical, chemical and biological methods have been used. Biological methods are considered to have a comparative advantage as cost effective and environmentally friendly technologies. Bioremediation, defined as the use of biological systems to destroy and reduce the concentrations of hazardous waste from contaminated sites, is an evolving technology for the removal and degradation of petroleum hydrocarbons as well as industrial solvents, phenols and pesticides. Microorganisms are the main bioremediation agents due to their diverse metabolic capacities. In order to enhance the rate of pollutant degradation the technology optimizes the conditions for the growth of microorganisms present in soil by aeration, nutrient addition and, if necessary, by adding separately prepared microorganisms cultures. The other factors that influence the efficiency of process are temperature, humidity, presence of surfactants, soil pH, mineral composition, content of organic substance of soil as well as type and concentration of contaminant. This paper presents a review of our ex situ bioremediation procedures successfully implemented on the industrial level. This technology was used for treatment of soils contaminated by crude oil and its derivatives originated from refinery as well as soils polluted with oil fuel and transformer oil
