Observers blinded to the experimental conditions tested the rats using the acetone/water spray tests at the same time on days 0–7 after oxaliplatin treatment. To estimate cold sensitivity of the paw, acetone (Kanto Chemical Co., Inc., Tokyo, Japan) or water (22 °C) was used, according to modification of previously described methods [33 (link)]. Rats were placed in a clear plastic box (23 × 23 × 12 cm) with a wire mesh floor and allowed to habituate for 30 min prior to testing. After habituation, 50 μl fluid (acetone or water) was sprayed on the plantar surface of the hind-paws five times using a MicroSprayer® (Penn Century Inc., Philadelphia, PA, USA). Paw withdrawal, defined as flinching, licking, or biting of the limb, was measured for 1 min after the start of the acetone spray. For the water spray test, mineral water at 22 °C was used. The effects of acetone or water spray were repeatedly evaluated over time after oxaliplatin (1, 3, and 6 mg/kg) or 5 % glucose administration. A group of animals given oxaliplatin or glucose was tested 1 day before drug administration and for 7 days after drug administration.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
