Primary taste discrimination in alloxan diabetic rats with restricted access to testant and water.

ABSTRACT

This study was conducted to assess the primary taste discrimination in 18 h water deprived control and alloxan diabetic rats for a period of 60 min duration by using two bottle choice paradigm. Different concentrations of sodium chloride, sucrose, urea and hydrochloric acid were used for salty, sweet, bitter and sour taste sensations respectively. Alloxan diabetic rats showed loss of discrimination for sucrose and urea solutions, increased sensitivity for low concentration of hydrochloric acid and no change in sodium chloride taste sensitivity.
