N. Kolodiy et al., WATER AND NACL CONSUMPTION IN LONG-EVANS RATS AND EGYPTIAN SPINY MICE, Bulletin of the Psychonomic Society, 31(4), 1993, pp. 261-264
Water and NaCl consumption in Long-Evans rats (Rattus norvegicus) and
Egyptian spiny mice (Acomys cahirinus) was examined after periods of a
cute water deprivation (0-100 h) and NaCl deprivation (via 0-10 mg/kg
furosemide i.p.). Rats' intake of water was monotonically related to t
he length of the deprivation period, with only nominal changes in wate
r intake observed for spiny mice. NaCl intake for rats was also monoto
nically related to furosemide dose, again with only nominal changes in
NaCl intake observed for spiny mice. The patterns of water and NaCl c
onsumption for rats were in agreement with those reported previously,
whereas similar observations have not been described for spiny mice. D
ifferences in adaptation to deprivation states were attributed to the
desert heritage and physiological characteristics of the spiny mouse.
