  • A 5-year-old intact female Persian cat was referred with anorexia and vomiting. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Ultrasonography revealed several findings including uniformly hyperechoic hepatic parenchyma compared to adjacent falciform fat, increased attenuation of the ultrasound beam, and poor visualization of intrahepatic vessel borders. Computed tomography revealed hypoattenuation of the hepatic parenchyma with a radiodensity value of -60 Hounsfield units. The adjacent intrahepatic vessels appeared hyperattenuated relative to the hepatic parenchyma as if the vessels were contrast-enhanced. Based on ultrasonography and computed tomography results, the cat was tentatively diagnosed as feline hepatic lipidosis.

  • The study was carried out to assess the developmental abnormalities induced by Cytotec in mice during intrauterine life. Pregnant mice were exposed to a single dose of 0, 0.02, 0.04, 0.06, 0.08 and $0.1{\mu}g$/g BW on day 8 of gestation. Fetuses were recovered on day 18 of gestation. These fetuses were subjected to morphological and morphometric studies. Morphological studies showed abnormalities like anophthalmia, microophthalmia, micromelia and syndactyly. In addition to these, resorptions were also encountered in the higher dose groups. Morphometric analysis showed an overall reduction in body weight, crown rump length, brain and eye circumference, pinna and snout size, length of fore and hind limb and tail size with a significant difference (p<0.001) compared to controls. The outcomes of histological studies revealed some brain defects like hydrocephaly, enlarged third ventricle and undifferentiated ectoneural cells and abnormalities of the heart included right auricle thrombosis and degeneration of trabecular zone.

  • Six adult female Murrah buffaloes of about 12 years were exposed to solar radiation during summer when minimum and maximum ambient temperatures were 27.1 and $44.1^{\circ}C$, respectively. The skin surface temperature at forehead, middle pinna, neck, rump, foreleg, hind legs were recorded using non-contact temperature measuring instrument and respiration rate and rectal temperature were measured throughout the 24 hours starting from 6:30 AM. The diurnal fluctuations and temperature gradients have been reported for buffaloes. During summer when ambient temperature and solar radiation was maximum, adult buffaloes were not able to maintain their thermal balance even after increasing the pulmonary frequency 5 - 6 times. The changes in skin temperature at various sites indicate that the temperature of skin surface not only varies in relation to exposure but also due to water diffusion and evaporation.

  • The purpose of this study was to compare the consistency of external ear measurements obtained by electronic digital caliper, photocopier scanning and digital photographic methods. Photogrammetric measurements were made after image editing software was used to optimize the brightness, contrast, size and image clarity. The CorelDRAW dimension tool was used to create a dimension line that measured the vertical and horizontal length between any two landmarks. Results of repeated measures analysis of variance revealed no significant differences in length and width of the pinna between the three methods. The reliability of the three measurement techniques showed a high degree of consistency. Further study and efforts could be extended to measurement hands, foots and facial dimensions by present techniques.

  • A new unrecorded species, Hypodematium squamuloso-pilosum Ching (Hypodematiaceae), previously known only in China, was newly found on the rocks of a limestone mountain in Yeongwol-gun, Gangwondo, Korea. This taxon is distinguished from H. glanduloso-pilosum (Tagawa) Ohwi, reported as a species of Hypodematium in Korea based on linear lanceolate scales on the rhizome and a stipe base, white long hairs throughout the leaves, rarely reddish brown curly linear scales on the stipe, and oblong-lanceolate basal pinna. This taxon was most similar to H. hirsutum based on the plant height, rhizome, scale shape and size, sori position, and indusium shape. A new Korean name, 'Huin-geum-teol-go-sa-ri', was given based on the long white hair throughout. Descriptions and illustrations of this taxon and a photograph of its habitat are provided from Korea.

  • The purpose of this study was to examine some acoustic characteristics in the ear canal. It was assumed that a sound outside the external auditory canal could be different from the sound inside the external auditory canal. The acoustic signals were captured by a probe microphone placed at a distance within 1 cm from the tympanic membrane, and a reference microphone was placed over the upper pinna. Three vowels /a/, /i/, /u/ were recorded from a normal adult male speaker. The parameters such as the formant frequency ($Fl\simF5$) and the peak intensity were measured using a speech analyser, PCquirer. It was found that the entering part of the external auditory canal functions as a narrowing point as to the speech that passes through the free field. Results show that acoustic characteristics were changed for speech discrimination rather than speech perception.

  • A 2-year-old, spayed female, Korean domestic short-hair cat was presented with depression and vomiting. The patient had history of weight loss lasting seven months. Physical examination revealed icterus in the pinna, oral mucosa, and sclera. Based on ultrasonography and computed tomography, tentative diagnosis was extrahepatic biliary tract obstruction with acquired portosystemic shunt (PSS). Tumor or inflammation of hepatobiliary system was suspected as the cause of obstruction of the common bile duct. But it could not be determined without biopsy. The severely dilated cystic duct was considered to cause portal hypertension and secondary multiple PSS. The patient expired without histopathologic examination.

  • The chigger is of importance to humans and animals as an irritating pest and a crucial vector of disease. We observed stylostome formation by larvae of Leptotrombidium pallidum in parasitized striped-field mouse (Apodemus agarius) pinna skin. The stylostome formations were also examined in detail by electron microscopy. The proximal and middle parts of the stylostome were formed as a rod-like structure containing a canal. The stylostome was coated with thick degenerated epidermal cells, and seemed to be formed a hyperplastic epidermis. The stylostome formation may result from an interaction between larval secretions and the host tissue. According to histological and morphological characteristics, the stylostome exhibited considerable inflammation in the epidermis and similar reactivity.

  • A 1.5-year-old neutered male domestic short hair cat was presented with multiple nodular mass, and suspected mast cell tumor on the surface of the right ear, accompanied by submandibular lymph node involvement. Histopathological Examinations and KIT (CD117) immunohistochemical staining was performed after the surgical resection of the entire right ear pinna. This patient was diagnosed with an anaplastic mast cell tumor with a diffuse positive cytoplasmic expression of KIT. Imatinib mesylate was prescribed after surgical resection; the patient presented without recurrence or metastasis for 2 years. Mild leukopenia was observed as the only side effect of imatinib mesylate during medication.

  • Formant frequencies depend on the position of tongue, the shape of lips, and larynx. In the auditory system, the external ear canal is an open-end resonator, which can modify the voice characteristics. This study investigates the effect of the real ear on formant frequencies. Fifteen subjects ranging from 22 to 30 years of age participated in the study. This study employed three corner vowels: the low central vowel /a/, the high front vowel /i/, and the high back vowel /u/. For this study, the voice of a well-educated undergraduate who majored in speech-language pathology, was recorded with a high performance condenser microphone placed in the upper pinna and in the ear canal. Paired t-test showed that there were significant difference in the formant frequencies of F1, F2, F3, and F4 between the free field and the real ear. For /a/, all formant frequencies decreased significantly in the real ear. For /i/, F2 increased and F3 and F4 decreased. For /u/, F1 and F2 increased, but F3 and F4 decreased. It seems that these voice modifications in the real ear contribute to interpreting voice quality and understanding speech, timbre, and individual characteristics, which are influenced by the shape of the outer ear and external ear canal in such a way that formant frequencies become centralized in the vowel space.
