成年Fischer-344(F-344)大鼠对任何浓度的NaCl溶液的偏好均低于水,事实上,在其他品系大鼠可靠偏好的溶液浓度下,避免使用NaCl。相反,据报道,许多品系的未成年大鼠表达了相对于成年大鼠的盐偏好升高。本研究通过测试断奶前(第10天)和断奶(第20-24天)F-344大鼠的盐偏好来检查F-344大鼠盐厌恶的发展。在第10天,在“毛巾测试”期间,F-344大鼠摄入的1%和2% NaCl溶液显著多于水,其偏好与该年龄段其他品系的偏好相当。到正常断奶时(第20-24天),F-344大鼠显示出对等渗范围内NaCl溶液的显著回避,并且它们的偏好与其他大鼠品系显著不同。这在24小时2瓶偏好测试以及25分钟“毛巾测试”中很明显。由于F-344大鼠的NaCl偏好在第10天与其他大鼠品系相当,但在第20天显著不同,因此在此期间必须发生改变,逆转NaCl刺激的享乐值。确定导致这种逆转的因素可能有助于深入了解F-344大鼠不喜欢盐和未成熟大鼠盐偏好升高的原因。
Adult Fischer‐344 (F‐344) rats fail to prefer NaCl solutions of any concentration to water and, in fact, avoid NaCl at solution concentrations which other strains of rats reliably prefer. In contrast, immature rats of a number of strains have been reported to express an elevated salt preference relative to adults. The present studies examine the development of the F‐344 rat's salt aversion by testing salt preference in the preweaning (Day 10) and weanling (Days 20–24) F‐344 rat. At Day 10, F‐344 rats ingested significantly more 1% and 2% NaCl solutions than water during “towel testing” and their preference was comparable to that displayed by other strains at this age. By the time of normal weaning (Days 20–24) significant avoidance of NaCl solutions in the isotonic range was displayed by F‐344 rats, and their preference was strikingly different from other rat strains. This was evident in a 24‐hr 2‐bottle preference test as well as a 25 min “towel test.” Since NaCl preference of F‐344 rats is comparable to other rat strains at Day 10 but dramatically different by Day 20, a change must occur during this time which reverses the hedonic value of NaCl stimulation. Identification of factors responsible for this reversal may provide insight into the causes both of the F‐344 rat's dislike of salt and the immature rats elevated salt preference.
