Measurement of extravascular lung water by the double indicator dilution method using heat and sodium in horses under general anesthesia.

Rapid infusion is believed to be harmful to the lung, however, the pathological status of pulmonary edema resulting from excessive fluid therapy in horses has not been clarified because the quantitative diagnosis of pulmonary edema is impossible. To evaluate the precision of the double indicator dilution method using heat and sodium in horses, which allows the quantitative diagnosis of pulmonary edema, we compared extravascular lung water volume measured using a lung water computer based on the theory of the double indicator dilution method with that determined by the direct method. The value of extravascular thermal volume (ETV) determined by the double indicator dilution method was 7.82 +/- 0.62 ml/kg and the detection ratio of ETV to the value of pulmonary extravascular water volume (PEWV) by the direct method was 0.996 +/- 0.038. There was a significant correlation between ETV and PEWV (P < 0.05), and the regression line was Y = 1.23 X - 1.73 with a correlation coefficient of 0.953. The value of extravascular lung water determined by the double indicator dilution method was significantly consistent with that obtained by the direct method, indicating the high precision of the double indicator dilution method in normal horse lungs.

Occlusion in temporomandibular disorders: treatment after occlusal splint therapy.

The concept of using the condylar path as the reference for occlusion is questionable for the patient whose temporomandibular joint has pathological changes because the condylar path of TMD patient deviates greatly. After occlusal splint therapy it is suggested that the patient's occlusion be treated using the Twin-Stage Procedure which does not require measurement of the condylar path. The research findings that occlusion controls the condylar path seems to support the concept that if the dentist creates the occlusion properly, the condylar path may be corrected and thereby minimise the micro-trauma which causes TMD.

Prevalence of upper respiratory tract disorders detected with a flexible videoendoscope in thoroughbred racehorses.

A total of 350 thoroughbred racehorses found clinically as having coughs or abnormal breath sounds underwent endoscopic examination of the upper respiratory tract at rest. As a result, abnormal endoscopic findings were obtained in all horses, demonstrating that thoroughbred racehorses with a clinical abnormality in the respiratory system necessarily had disorders in the upper respiratory tract. Whereas 11 types of disorder were observed, a combination of three different types of disorder were found in the highest frequencies in 3-, 4- and 5-year-old horses (27.8%, 29.2% and 29.7%, respectively). Among 6-year-olds or older horses, those having only one type of disorder accounted for the greatest proportion (47.6%). The prevalence of pharyngeal lymphoid hyperplasia or abnormalities of the epiglottis decreased with age.

Assessment of the sedative effect of medetomidine and determination of its optimal dose in thoroughbred horses.

The present study was carried out to assessing the sedative effect of medetomidine and determining its optimal dose in thoroughbred horses. Excessive ataxia after sedative treatment is dangerous for horses. Therefore three doses which may cause sufficient sedation with only mild ataxia were examined. Response to stimulation and the severity of ataxia suggested that 7.5 micrograms/kg BW, i.v., is optimal.

Determination of the minimum alveolar concentration (MAC) and physical response to sevoflurane inhalation in horses.

The minimum alveolar concentration (MAC) of sevoflurane required to prevent gross purposeful movement in response to electrical stimulation of the oral mucous membranes was determined in horses, and their physical responses to inhalation of this anesthetic were observed. The MAC was 2.31 +/- 0.11%. The horses showed good ventilation, without any signs of airway irritation such as coughing. The horses became slightly excited before they laid down. The end tidal sevoflurane concentration (ESC) required to produce recumbency was 2.54 +/- 0.11%. These results suggest that sevoflurane is a clinically useful anesthetic agent in horses.

Porcelain laminate veneers with three-dimensional shade reproduction.

A new system for creating porcelain veneers with three-dimensional shade options is described. The development of a new porcelain consisting of an intense colour which provides natural tooth aesthetics in layers of only 0.5 mm has made the system possible. In addition a masking porcelain may be used over discoloured tooth tissue. The new system is claimed to supersede the sometimes less aesthetic shades created with other laminate systems, as well as enhancing the marginal integrity of the veneer.

Twin-tables technique for occlusal rehabilitation: Part I--Mechanism of anterior guidance.

Anterior guidance and the condylar path have been considered independent factors. In a recent study, it was revealed that the anterior guidance influenced the working condylar path and even changed when the lateral incisal path deviated from the optimal orbit. This supports the hypothesis that anterior guidance and condylar path are dependent factors. When setting anterior guidance, it is recommended to set the working condyle so that it moves straight outward along the transverse horizontal axis. The angle of hinge rotation created by the angular difference between anterior guidance and condylar path assists the posterior disclusion, but is not solely responsible. The anatomy of the cusps is created by establishing the appropriate form of the posterior cusps aligned to the condylar path so that it also contributes to posterior disclusion. Posterior disclusion is crucial in controlling harmful lateral forces. The molars must disclude slightly more than the deviation in the condylar path to avoid occlusal interferences.

Twin-tables technique for occlusal rehabilitation: Part II--Clinical procedures.

Molar disclusion is determined by the cusp-shape factor and the angle of hinge rotation. A new twin-tables technique has been introduced for developing molar disclusion by using two incisal tables. It is a relatively uncomplicated technique and does not require special equipment. The final prosthesis with the twin-tables technique ensures a restoration with a predictable posterior disclusion and anterior guidance in harmony with the condyle path.
