Amputasi kaki depan adalah salah satu tindakan operasi yang dilakukan pada seekor kucing akibat adanya trauma pada kaki depan yang tidak mungkin untuk disembuhkan. Seekor kucing domestic short hair jantan berusia 1 tahun tidak dapat berjalan, dibawa oleh klien ke Rumah Sakit karena tertabrak kendaraan satu minggu sebelumnya. Kondisi luka terbuka pada kaki depan kanan mengalami abses dan berbau busuk. Krepitasi teraba pada tulang yang mengarah ke kondisi fraktur pada tulang radius ulna. Operasi amputasi kaki depan diambil sebagai langkah untuk menyelamatkan kehidupan pasien. Terapi post operasi yang diberikan antara lain analgesik, NSAID, antibiotik, dan multivitamin. Luka pascaoperasi sembuh dengan baik dan tidak ada komplikasi. Kucing mulai belajar berjalan menggunakan ketiga kaki yang lain pada hari ketiga.

Abstract Raramuri Criollo (RC) are one of 33 known biotypes of heritage Criollo cattle that exist throughout the Americas today. They have been raised by the Tarahumara peoples of the Copper Canyon in Chihuahua, Mexico, for over 400 years and exhibit remarkable rusticity and adaptation to harsh grazing environments. To date, no quantitative phenotypic description of this biotype exists. Our objective was to characterize RC cattle via 26 phenotype traits to provide a preliminary biotype standard. Twenty-eight multiparous RC cows, 4 primiparous heifers, and 4 bulls were selected from a purebred herd of approximately 200 animals at the USDA-ARS Jornada Experimental Range. These 36 animals were selected by a Criollo cattle expert based on body conformation correctness. SAS 9.4 was used to determine means, SEs or frequency of measured traits. Multiparous pregnant and cycling cows averaged 366.8 ± 9.8 kg live body weight, 121.8 ± 0.9 cm withers height, horn widths of 60.3 ± 1.6 cm, horn diameters of 5.7 ± 0.1 cm, chest girths of 183.6 ± 12.0 cm, hip widths of 44.5 ± 0.5 cm, flank girths of 52.2 ± 0.9 cm, body length of 90.0 ± 1.7 cm, neck lengths of 52.0 ± 0.9 cm, and tail lengths of 83.3 ± 1.4 cm. Bulls consistently averaged higher values for all traits and weighed 618.2 ± 9.8 kg with scrotal circumferences of 36.8 ± 0.7 cm. RC cattle exhibited mostly convex nose bridges (89%), open-back horns (49%), black muzzles, hooves, and eyes (62, 69, and 81%, respectively), small ears (78%), oblique eyes (70%), high-set tail heads (86%), short hooves (95%), and short hair (78%). Our preliminary characterization of RC phenotypes will be useful in selecting RC individuals for genotypic evaluation to eventually maintain a distinct purebred registry of this Criollo biotype.

The avian auditory papilla contains two classes of sensory receptor, tall hair cells (THCs) and short hair cells (SHCs), the latter analogous to mammalian outer hair cells with large efferent but sparse afferent innervation. Little is known about the tuning, transduction, or electrical properties of SHCs. To address this problem, we made patch-clamp recordings from hair cells in an isolated chicken basilar papilla preparation at 33°C. We found that SHCs are electrically tuned by a Ca2+-activated K+ current, their resonant frequency varying along the papilla in tandem with that of the THCs, which also exhibit electrical tuning. The tonotopic map for THCs was similar to maps previously described from auditory nerve fiber measurements. SHCs also possess an A-type K+ current, but electrical tuning was observed only at resting potentials positive to −45 mV, where the A current is inactivated. We predict that the resting potential in vivo is approximately −40 mV, depolarized by a standing inward current through mechanotransducer (MT) channels having a resting open probability of ∼0.26. The resting open probability stems from a low endolymphatic Ca2+ concentration (0.24 mM) and a high intracellular mobile Ca2+ buffer concentration, estimated from perforated-patch recordings as equivalent to 0.5 mM BAPTA. The high buffer concentration was confirmed by quantifying parvalbumin-3 and calbindin D-28K with calibrated postembedding immunogold labeling, demonstrating >1 mM calcium-binding sites. Both proteins displayed an apex-to-base gradient matching that in the MT current amplitude, which increased exponentially along the papilla. Stereociliary bundles also labeled heavily with antibodies against the Ca2+ pump isoform PMCA2a.

Pupillary Reflex

Korneal squestrum merupakan suatu keadaan yang terjadi pada kornea yang telah mengalami kornea ulser dalam kurun waktu yang panjang/kronis. Kornea merupakan struktur pada mata bagian depan yang memiliki warna transparan dan tersusun atas outer epitelium, middle stroma dan inner endothelium. Pemeriksaan dasar yang dilakukan pada pasien adalah menace, dazzle dan pupillary reflex. Sedangkan pemeriksaan penunjang yang dilakukan adalah schiemer tear test dan fluorescein test. Hasil pemeriksaan dasar menunjukkan hasil yang positif tanpa adanya gangguan penglihatan. Sedangkan hasil fluorescein test menunjukkan hasil positif kornea ulser dengan adanya pendaran warna hijau. Terapi dilakukan dengan memberikan antibiotik (cendo genta 0,3%) s.6.d.d selama 2 minggu. Respon possitif ditunjukkan oleh pasien dengan hasil fluorescein test negatif pasca 2 minggu pengobatan. Akan tetapi, masih terdapat jaringan-jaringan berwarna putih kecoklatan yang menutupi permukaan korneal. Terapi dilanjutkan dengan memberikan cendoxitrol s.2.d.d selama 2 minggu. Respon yang diberikan pasien kurang baik, jaringan berubah menjadi kecoklatan atau disebut dengan korneal squestrum.

1. Single-neuron behavior in the cochlear nerve of neonatal (3-day-old) chicks was examined after exposure to a 120-dB SPL pure tone (0.9 kHz) for 48 h. Exposed animals were tested after 0 days or 12 days of recovery. Nonexposed chicks, age-matched to the exposed animals, formed two control groups. 2. Spectral response plots were obtained from each cell. These plots described the neuron discharge rates in response to 1,767 tone burst stimuli, each with a unique frequency-intensity combination. The tone bursts were presented at frequencies between 0.1 and 4.5 kHz and for intensities between 0 and 100 dB SPL. From these plots the characteristic frequency (CF), CF threshold, and sharpness of tuning (Q10 dB) were derived for each cell. Frequency response-area functions at selected stimulus levels and rate-intensity functions at the CF were also constructed from the spectral response plots. In addition, spontaneous activity was determined. Data were obtained from 903 cells. 3. Neuron activity in the control cells revealed no differences between CF thresholds, Q10 dB, or spontaneous activity in the two age groups. However, age differences at all frequencies were noted in the rate-intensity functions. 4. A frequency-dependent loss in CF threshold was observed in the 0-day recovered cells. The threshold shift (relative to age-matched control cells) was 55-65 dB between 0.8 and 1.5 kHz, but only 10-15 dB between 0.1-0.4 kHz and 2.5-3.5 kHz. The exposed cells showed no loss in frequency selectivity (Q10 dB) at < 0.5 kHz, whereas above this frequency an increasing deterioration in tuning was noted. Spontaneous activity in the 0-day cells was suppressed across the entire range of CFs. The rate-intensity function of exposed cells had a steeper growth rate than that of control cells. 5. At 12 days of recovery, CF threshold, Q10 dB, and spontaneous activity all recovered to the levels exhibited by age-matched control cells. However, the rate-intensity function for cells with CFs between 0.8 and 1.0 kHz showed abnormal growth and higher discharge rates at saturation than the control cells. Outside of this frequency range the rate-intensity functions of control and exposed cells were similar to each other. 6. Recovery of function in the sound-damaged chick ear is accompanied by almost complete repair of the basilar papilla. The tectorial membrane, however, retains a major defect and only the lower layer of this membrane regenerates. An important observation in this presentation was the abnormal rate-intensity functions (in the 12-day recovered cells) reported for frequencies served by that region of the sensory epithelium where the tectorial membrane defect was found. This observation may be related to sustained structural damage to the short hair cell region of the papilla and/or alterations in the efferent control of papilla function mediated by the short hair cells.

Muscle Biopsies

An eight-month-old, male, neutered, domestic short hair cat was presented for further investigation of white granuloma-like lesions on the tongue and recent onset regurgitation. The owner reported that the cat had an ‘unusual’ gait. Moderate increases in alanine aminotransferase, aspartate aminostransferase and markedly elevated creatine kinase were present. Thoracic radiographs revealed moderate-to-severe oesophageal impaction, cardiomegaly and an irregular appearance of the diaphragm. Endoscopy revealed a distended oesophagus with accumulation of ingesta. Difficulties were encountered when passing the endoscope through the cardia. Histology of the white granuloma-like lesions were pathognomonic of calcinosis circumscripta. These features raised the suspicion of feline muscular dystrophy. Muscle biopsies and electromyography were declined, and the patient was euthanased. Postmortem examination, histopathology and immunohistochemistry were suggestive of dystrophin-deficient muscular dystrophy (DDMD). This case emphasises the importance of including DDMD as a differential diagnosis for regurgitation and lingual calcinosis circumscripta in cats.

1. With the use of whole-cell mode of the patch-clamp method, we examined the electrical responses of hair cells enzymatically isolated from the goldfish sacculus. 2. Hair cells from the rostral saccule had a short cell body and were ovoidal or eggplantlike in shape, whereas hair cells from the caudal saccule had a variable shape. Many had a longer cell body and were cylindrical or gourd-like in shape, but some short hair cells were also present in the caudal saccule. 3. The short hair cells had a resting potential of about -75 mV. In current-clamp experiments, these hair cells elicited damped oscillatory-potential changes of a relatively small amplitude in response to a depolarizing current. A current in the opposite direction produced a slow hyperpolarization, much larger in amplitude. 4. Resonant frequency of the short, or the oscillatory, type of hair cells ranged from 40 to 200 Hz or higher. However, resonance was generally of a poor quality as compared with that noted for hair cells in the turtle cochlea or frog sacculus. 5. The long hair cells had a resting potential of -90 to -100 mV. In current-clamp experiments, these hair cells elicited an all-or-none spike approximately 50 mV in amplitude in response to a depolarizing current. The spike was usually followed by a plateau, which was maintained for the duration of the depolarizing pulse. In some hair cells, damped slow oscillatory waves were evoked at a rate of 5-15 Hz. On the other hand, a hyperpolarizing current produced potential changes much smaller in amplitude. 6. Voltage-clamp experiments showed that Ca2+-activated K+ channel and A-current, especially its high-threshold subclass, were involved in the generation of outward rectification in the oscillatory-type hair cells. On the other hand, Na+, in addition to Ca2+, was involved in the generation of spike in the spike-type hair cells. Spike potentials were elicited even in the presence of tetrodotoxin (TTX), but the rate of rise was slower as compared with the intact spikes. 7. The spike-type hair cells had an inwardly rectifying K+ channel similar to that noted in the tunicate egg and chick vestibular hair cell. However, the oscillatory-type hair cells had an inwardly rectifying channel similar to the hyperpolarization-activated current, Ih, of the rod inner segment, or sinoatrial nodal cell, or lacked the inwardly rectifying channel. Differences in the resting membrane potential between the oscillatory- and spike-type hair cells are probably related to differences in the inwardly rectifying channels. 8. Effects of sound stimulation were simulated by injecting a half-wave rectified sinusoidal current of various frequencies.(ABSTRACT TRUNCATED AT 400 WORDS)
