P REVIOUS reports have given a description of the cyclic changes in excitability of both auricle and ventricle of the dog’s heart (I, 2). It was found that the dog’s auricle is ‘vulnerable’ to fibrillation throughout the major dip area of the excitability-recovery curve (3). A study of ventricular vulnerability has now been made. Cats and turtles were used almost exclusively in this investigati...

The validity of the serial compartment analysis of dye dilution curves was tested by injecting dye into the right auricle, pulmonary artery, a pulmonary vein and the aorta consecutively while sampling blood from the carotid artery. It was found that the serial compartment analogy is valid and that the lungs tire the largest volume in the series. In curves obtained by injecting into the pulmonar...

Ramsay Hunt syndrome is an infectious disease caused by the varicella zoster virus. It is characterized by the symptoms of facial paralysis, otalgia, and erythematous vesicular rash on the auricle and/or oral cavity. We present a case of a patient with clinical evidence of Ramsay Hunt syndrome involving the cranial nerves VI, VII, and VIII. The patient, a 66-year-old woman, showed left facial p...

The formation of developmental boundaries is a common feature multicellular plants and animals, impacts the initiation, structure function all organs. Maize leaves comprise proximal sheath that encloses stem, distal photosynthetic blade projects away from plant axis. An epidermally derived ligule joint-like auricle develop at blade/sheath boundary maize leaves. Mutations disturbing ligule/auric...

Primary tumours of the heart are uncommon. Various authors estimated their frequency at autopsy as follows: Rand and Sachs (1943), o.5 per cent.; Straus and Merliss (I945), 0.0017 per cent.; Lymburner (1934), o.6I per cent. About three-quarters are benign and about half of the benign tumours are the so-called myxomas. Approximately 70 per cent. of these myxomas arise in the left auricle in the ...

Endochondral pseudocyst of the auricle is an uncommon, though distinctive clinicopathological entity occurring mainly in young men. An additional case is reported and the differential diagnosis and pathogenesis discussed. It is suggested that lymphatic dilatation of normally present tissue planes could be the most likely causative mechanism. Minor trauma to susceptible ears also seems to be a r...

Cortical areas that control ear movement have not been reported in humans. We describe a rare case in which ear auricle movement was induced by extraoperative electrical cortical stimulation. A 21-year-old man with intractable localization-related epilepsy was admitted for presurgical evaluation. Subdural electrodes were implanted over the right temporal and frontal regions. Tonic upward contra...

INTRODUCTION Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are non-melanoma skin cancers (NMSCs) and are the most common malignancies in Caucasians. The purpose of our study was to examine the frequency of the histological types of NMSC located on the auricle, and to determine whether national and international guidelines on NMSC treatment were followed in our ear, nose, and thro...
