Phenolic compounds were extracted with 60% methanol (after purification with acetone) from the ears of two winter triticale cultivars (Dagro and Malno). Total phenols were determined and five phenylpropanoid acids were identified. Separation of phenylpropanoids was carried out in a H PLC column - C,8 Eurospher with the use of KNAUER isocratic system. A mixture of methanol- -0.1 M KH2P04 (55: 45) was used as a mobile phase. The obtained results showed that the contents of total phenols and caffeic acid were higher in Malno than in Dagro. The concentration of four other phenylpropanoid acids was higher in Dagro.

Dizziness is a symptom of many diseases. Patients very frequently come with such ailment to the hospital emergency department. It is a state which may last a few seconds or minutes and increase or recede with time. Therefore, the admitted patients frequently cannot assess their own illness in a precise and objective way. The dizziness definition is also quite ambiguous. Dizziness is defined as the sensation of one own’s body movement or spinning and movement of the surrounding. It is very important to record the patient’s medical history since the diagnostic procedure may depend on the symptoms’ character. Dizziness may be a symptom of a serious disease, although it is not easy to find its cause. It appears not only in case of the labyrinth and nervous system disorders, but also in the systemic and functional diseases. Dizziness and balance disorder are the direct cause of admitting one in every thirty patients. The symptom indicated the directly life-threatening disease only within the 3-8.5% of patients (cerebral circulation insufficiency - 6%, cardiac dysrhythmia – 1.5%, brain tumour < 1%). Analyzing the data concerning the problem of dizziness occurrence within the general population, it has been noticed that this symptom has been reported two or three times more frequent by women than by men. Dizzinesses are classified pathogenetically and clinically into labyrinthine and non-labyrinthine, paroxysmal and permanent, acute and chronic. Dizziness is hard to diagnose because the symptoms reported by patients are only their own subjective sensations. The data presented in the article implicate the increasing number of patients with such disorders. Apart from dizziness, the patients complain also about the hearing disorders and nausea, which make their proper functioning impossible. It is inappropriate to start the treatment without knowing the cause. Establishing, on the basis of patient’s medical history and physical examination, whether the dizziness is of peripheral or central origin, is essential for the further diagnosis. After establishing the main diagnosis, the casual and symptomatic treatment is implemented, in some cases - there is a vestibular rehabilitation or even a surgical treatment.

A partial cranial endocast and right inner ear of the Cretaceous abelisaurid dinosaur Aucasaurus garridoi were digitally reconstructed from CT scans. The forebrain, midbrain, and hindbrain resemble the morphology described for the abelisaurids Majungasaurus and Indosaurus. However, Aucasaurus exhibits a floccular process that is relatively larger than that of Majungasaurus. In Aucasaurus the flocculus is enclosed in an 8-shaped floccular recess, similar in shape and size to that observed in Abelisaurus, suggesting that the two Patagonian taxa were capable of a slightly wider range of movements of the head. Here we describe the second inner ear known for the Abelisauridae. The labyrinth of the inner ear is similar in shape and size to the semicircular canals of Majungasaurus, although the lateral semicircular canal is shorter in Aucasaurus.

Wings are the most obvious adaptation bats have for powered flight and differences in wing morphology are known to correlate with flight behaviour. However, the function(s) of ancillary structures such as the ears and tail, which may also play an important role during flight, are less well understood. Here we constructed a simplified model of a bat body with ears based upon morphological measurements of a brown long-eared bat (Plecotus auritus) to examine the aerodynamic implications of flying with large ears. The forces and moments produced by the model were measured using a sensitive 6-component force and torque balance during wind tunnel testing. The large ears of the model bat produced positive lift as well as positive drag of the same order of magnitude. At small ears angles (0° to 10°), increasing the angle of the ears resulted in an increase of the lift-to-drag ratio. At higher ear angles (> 10°) separation of the flow occurred which caused a large decrease in the lift-to-drag ratio produced. To maximise the benefit from the ears (i.e., lift-to-drag ratio) our model predicts that a horizontal free flying P. auritus should hold its ears at an approximate angle of 10°. The results of the pitching moment coefficient are inconclusive in determining if the large ears are important as flight control structures. The additional drag produced by the ears has consequences for the foraging behaviour of P. auritus with reductions in its flight speed and foraging range.

The aim of the study was to find out the potential prognostic value of proliferation activity and apoptosis in cholesteatoma and granulation tissue removed during middle ear reoperation in recurrent middle ear inflammation. Granulation tissues and recurrent cholesteatoma were analysed after being surgically removed from the middle ear in a group of 25 patients qualified for middle ear reoperation procedure. Paraffin sections were stained with haematoxylin and eosin according to Mallory’s method. Immunohistochemical reaction Anti-PCNA was performed. Apoptosis was evaluated using the TUNEL method. The percentage of PCNA-positive cells was 42–95% in the matrix of the cholesteatoma and 29–81% in the perimatrix. In the granulation tissue it was 35–75%. The percentage of apoptotic cells was 12–73% in the matrix of the cholesteatoma, 5–72% in the perimatrix and 1–65 % in the granulation tissue. The prognostic value of the parameters studied in the recurrent middle ear inflammatory process is questionable, probably due to the small number of cases under examination.

To determine the staphylococcal colonization pattern in healthy and diseased dogs, living in two particular environments, a number of microbiological samples were taken. Overall, twenty dogs, either healthy or with infected skin lesions, were examined. In each case bacterial swabs were collected from the nasal mucosa, ear, perineum, lumbo-sacralis triangle, and from the infection sites if such were present. A total number of 104 isolates representing different staphylococcal species were isolated and identified using routine biochemical methods applied in diagnostic laboratories. Among 17 isolated staphylococcal species, Staphylococcus intermedius was the most common species isolated from both healthy or diseased dogs living either in animal shelter or household environments. The pattern of Staphylococcus sp. colonization differs considerably for animals living in the two tested habitats. In particular, S. aureus MRSA and MSSA isolates were detected only in infected skin lesion samples from animals that dwelled in the animal shelter. As could be expected, S. intermedius was found to be a predominant causative agent in canine skin infections. In our study, we demonstrated that S. intermedius in its carrier-state, inhabits mainly the mucosal membrane of the nasal vestibule. It was also found in the samples taken from the skin, the lumbo-sacralis triangle and perineum, but was rarely isolated from the ears.

Based on careful tissue processing, detailed structural analysis, and histochemical as well as cytophotometrical evaluation of the epidermis, the study presents data with respect to changes of tissue integrity during two storing modes (room temperature and 4°C) and various storage times of the porcine auricle. Structural degeneration was first noted in the barrier region of the epidermis from where such changes spread, independent of storage conditions, from small horizontal necrotic islands and continuously with increasing storage time. The histochemical results corroborated these observations, emphasizing, however, that the lower epidermal layers seemed intact for a longer time period than the upper layers. Cytophotometrical evaluation of histochemical stainings showed, with regard to the enzyme succinate dehydrogenase, that oxidative metabolism was negatively affected in the early stages of storage, whereas epidermal lipids (neutral fats, glycolipids) remained relatively stable, even during storage at room temperature. In conclusion, it was obvious that the barrier region is the most sensitive element of the porcine ear epidermis. Taking into consideration that this part of the epidermis is most important for permeation studies, it seems reasonable to avoid any storage of porcine auricles at room temperature, and to use only auricles that have been stored at 4°C for not more than 4 to 6 hours, immediately after delivery from the slaughter-house. In this way better tissue preservation can be achieved, whereby the use of shinkage-free water-soluble plastic embedding would generally improve the histological control of structural integrity, and the application of an easy to handle enzyme histochemical procedure (e.g. succinate dehydrogenase demonstration) to unfixed fresh-frozen sections would help to control basic aspects of tissue functions. The results are discussed in relation to the use of porcine integument as a model in human dermatological research.
