Opis:: Purpose:To examine lipid peroxidation, antioxidant protection and L-arginine-NO – system in patients with papulo-pustular rosacea.Materials and methods:The study included 128 women with papulo-pustular rosacea aged 40.1±0.99 years (range: 18-68 years). The patients were divided into three groups based on the severity of the symptoms: group I –patients with mild rosacea (n=42), group II – patients with moderate rosacea (n=49), group III – patients with severe rosacea (n=37). Indicators of lipid peroxidation and antioxidant protection were defined in all patients by a spectrophotometric method.Results:The first group of patients showed a significant decrease in superoxide dismutase (SOD) and ceruloplasmin when compared to the control group. A significant increase in diene conjugates (DC), malondialdehyde (MDA), liposoluble antioxidants (retinol, α-tocopherol) and decrease in SOD, catalase and ceruloplasmin were observed in the second group. Patients in the third group had similar dynamics with a worsening of lipid peroxidation.Conclusions: The changes in some parameters of lipid peroxidation and antioxidant protection were revealed in patients with papulo-pustular rosacea. The nature of these changes depends on the severity of the disease. Evaluation of the antioxidant imbalance may be informative to determine the understanding of the genesis of dermatosis and to study therapeutic strategy aimed at reducing the generation of reactive oxygen species (ROS), leading to a decrease in the capacity of the antioxidant defense.

Opis:: Rhinophyma stanowi zaawansowaną postać trądziku różowatego. Guzowaty przerost nosa zewnętrznego jest schorzeniem o wieloletnim, przewlekłym przebiegu. Sam trądzik różowaty, stosunkowo często występujący, spotykany jest głównie u kobiet. Natomiast zaawansowane zmiany o typie rhinophyma występują zwykle u mężczyzn w 5–6 dekadzie życia. Etiopatogeneza choroby jest wieloczynnikowa i nie została ostatecznie poznana. Wiadomo, że w początkowych etapach dochodzi do zaburzeń w mikrokrążeniu w obrębie nosa i przerostu gruczołów łojowych. W ciągu lat następuje powolny rozrost i włóknienie skóry i tkanki podskórnej w obrębie nosa, co prowadzi do powiększenia i deformacji nosa. Zmieniony chorobowo, rozrośnięty, o zapalnie zmienionej powierzchni nos stanowi defekt estetyczny chorego. Może być również przyczyną obturacji przewodów nosowych. W latach 1992–2013 w Klinicznym Oddziale Chirurgii Szczę- kowo-Twarzowej obserwowano 5 chorych z przerostem guzowatym nosa. Poniżej przedstawiono opis przypadku chorego, który w ostatnim czasie był leczony w tut. Oddziale.
Rhinophyma is a late manifestation of rosacea. Nodular hypertrophy of the external nose is a chronic disease lasting for many years. Rosacea itself is a frequent disease most common among women, yet its manifestation resulting in rhinophyma is typical for men in their 50s and 60s. The etiopathogenesis of rosacea is complex and not yet investigated thoroughly. Early stages are characterized with disruption of microcirculation in the nose and hypertrophy of sebaceous glands. Over the years skin and subcutaneous tissues proliferate and become firous leading to enlargement and malformation of the nose. Lesions pose not only a cosmetic defect, but may also cause obstruction to the nasal passage. Between 1992 and 2013 fie patients who presented with rhinophyma were treated at the Clinical Department of Maxillo-Facial Surgery of Provincial Specialist Hospital in Rzeszów. A case study of a patient who was recently treated at the clinic is presented below.

Opis:: Vertical distribution of species richness of various groups of organisms within trees is still insufficiently understood. The reason for this are, among others, the difficulties in accessing standing trees. The aim of the study was to determine the differentiation of species richness of fungi, lichens and lichenicolous fungi and bryophyte of three tree species (oak, birch and pine) within windthrow areas in the Kampinos National Park (central Poland). Ten individuals of each tree species were chosen. They were only thrown, not broken, without serious damage, still alive and easily accessible. The investigations of species composition were performed in five parts of each tree: trunk bottom, lower trunk, upper trunk, lower crown and upper crown. Individual parts of the trees were measured, than their surface and volume were determined. The species richness of the studied groups of organisms was calculated using rarefaction curves based on the number of samples, volume and area of the distinguished tree parts. Species composition changes of the tree parts were described using non−metric multidimensional scaling. The most important parts of trees for fungi were the crowns of trees, in particular oak’s. The highest richness of lichens was found within the crown of oaks, however they were recorded within all of the distinguished tree parts. The highest richness of bryophytes was recorded in the lower crown of oak and the trunk base of birch, but this group of organisms generally did not inhabit the birch and pine crowns. In the case of rarefaction curves based on the number of samples, the large positive meaning of the oak was observed, however the observed pattern was different when the volume and surface were taken into account. The general species richness of the studied taxa was similar for three tree species, the pine was distinguished positively in case of fungi, birch – in the case of lichens and oak – in the case of bryophytes. The species of trees differ from each other in terms of the species composition of the studied groups of organisms. We also observed the gradual change in the species composition from the base of the trunk to the upper crown.
