Effects of High Plasma Phenylalanine Concentration in Older Early-Treated PKU Patients: Performance, Neurotransmitter Synthesis, and EEG Mean Power Frequency Wilma L. Krause, Margaret . The purpose of this study was to evaluate the toxicity of L-phenylalanine when administered daily in the diet to rats for at least 28 days. Male and female Crl:CD®(SD)IGS BR rats were assigned to four groups. Each group received diets containing basal diet or , , or % (w/w) L-phe-nylalanine. Studies were performed to exclude changes in pool size of precursor (l-phenylalanine-(14)C) or product (amylase) in accounting for decreases associated with fasting. These studies demonstrate that fasting was associated with decreased rates of pancreatic amylase and protein synthesis in rats. Indeed, the experiment reveals a clear dose-dependent suppression of food intake by phenylalanine (Fig. 1). The second experiment compared the effects of capsulated phenylalanine ( g), aspartame Cited by:

The effect of hypothalamic lesions on feeding. Lateral lesions produce thin, anorectic rats, whereas medial lesions result in obese hyperphagic rats. The Dual Center Hypothesis evolved about fifty years .   He was a senior lecturer, and eventually was appointed chair at the Glasgow University Zoology Department in He has studied behavior, hybrid vigor and effects of breeding at a low temperature in rats and mice .   This being said, there are many obvious and important differences in feeding behavior between mice and humans. Laboratory mice are nocturnal and consume most of their food in frequent, small meals throughout the dark. By comparison, humans tend to consume most of their calories Cited by: Rats exhibit aggressive behavior when threatened. They may fight, chase, bite and box. Rats also display some behaviors such as sidling and belly-up defensive postures. Rats dwell in cities, suburbs and rural areas. They are capable of thriving in human environments are therefore are considered a commensal rodent.

Once again, there was no treatment effect on hunger, mood, and arousal. We conclude that Phe, when given as the free amino acid or as APM, in doses up to 10 g, does not affect feeding behavior in Cited by: 3. 1. Physiol Behav.

Because these studies did not consider the confounding effect of changes in food intake, it remains unclear whether ovarian hormones regulate body composition independently of their effects on food intake. We utilized a pair-feeding paradigm to examine the effects .
