RESUMO
Temperature detection and temperature preference are critical for the maintenance of thermal homeostasis and protection from noxious temperature. Methods to measure the time spent on plates of different temperatures such as the two-plate test and thermal-gradient test are generally used to evaluate temperature preference. In this study, we established a temperature preference test that assesses water drinking behavior by modifying the two-bottle taste preference test. We found that mice in a common-temperature environment of 23 °C avoid drinking water more than 40 °C. While mice in a common-temperature environment preferred 10 °C and 30 °C water equally, mice in a hot environment at 35 °C preferred to 10 °C water compared to 30 °C water. Moreover, mice in a cold environment of 10 °C did not avoid drinking 40 °C water compared to 10 °C water. From these results, the temperature preference test that we developed could be used to evaluate temperature preference owing to the ambient temperature changes.
RESUMO
An 80-year-old woman presented with acute abdominal pain and distention. A diagnosis of acute chylous peritonitis was made via contrast-enhanced computed tomography and abdominal paracentesis. She underwent ultrasound-guided intranodal lymphangiography with Lipiodol® (IL with Lipiodol), and her persistent abdominal pain was significantly reduced within a day. Moreover, her ascitic fluid showed marked improvement and paracentesis was no longer needed. Based on the findings of the study, IL with Lipiodol could be a promising minimally invasive approach in the treatment of acute chylous peritonitis.
