Effects of neonatal treatment with monosodium-glutamate in spontaneously hypertensive rats

Following neonatal treatment with monosodium-glutamate (MSG), blood pressure in adult spontaneously hypertensive rats (SHR) was markedly lower than in control SHR, with only a small decrease in normotensive Wistar-Kyoto controls (WKY). In addition, in MSG-treated SHR an increase in pain-sensitivity was found and both strains showed increased water intake and reduced organ and body weights as compared to vehicle-treated rats.
