Serum Amino Acid Concentrations in Nine Athletes Before and After the 1993 Colmar Ultra Triathlon

“…the entry of AAA into the brain may be favoured (27,38). In line with this, the cerebrospinal fluid -AAA concennation was increased by 100-400% in patients suffering from hepatic encephalopathy (32). An increased brain tryptophan concentration was also observed in exhausted rats (4.30.31) with an increased hypothalamic 5-hydroxy-tryptamine concentration, but to a lesser extent in trained animals, possibly reflecting a training-dependent improved fatigue or stress tolerance.…”

“…The baseline serum amino acid concentration was approximately 40 % higher in the triathletes ( Table 3) compared to untrained subjects (32). Einspahr and Thorp (9) as well as D6- 'p c 0.05; "p c 0.01; "'p < 0.001; "Iflot significant combaz et al (6) also described approximately 20% higher levels in endurance athletes, but there were considerable concentration differences in some individual amino acids between these three studies.…”

“…however, remained significantly higher than usually observed in patients suffering from hepatic encephalopathy with significantly increased cerebrospinal fluid levels of tyrosine. phenylalanine and tryptophan (32). However, to view central fatigue as solely related to an increase in brain tryptophan and 5-hydroxytryptamine concentration seems too simplistic and attempts to delay fatigue during prolonged exhaustive exercise by supplementation of BCAA to avoid the decrease in BCAA-AAA-ratio have produced contradictory results.…”

“…Central fatigue, originating in the brain by an excitation < inhibition dysbalance is assumed during prolonged exhaustive exercise and in overtrained athletes (23,27,38), based on a plasma (serum) amino acid imbalance (5,6,9.27,30,31.38) which in part resembles the amino acid profile in patients suffering from hepatic encephalopathy (32). The BCAA (leucine, isoleucine, valine) were found to remain unchanged after completing a marathon (5) or to be reduced after a 30 km run, a marathon (2, 29,30), and a 100 km-run (6) combined…”

Pneumocystis pneumonia

“…As is indicated in the title of his article (" About the non-syphilitic interstitial pneumonia of early infancy "-translated from the German title), he drew attention to the fact that this disease had to be separated from congenital syphilis of the lungs (pneumonia alba), with which it could easily be confused. Rossle (1928) and also Loeschcke (1928) had briefly remarked upon the existence of a non-syphilitic interstitial pneumonia in infants. Benecke (1938), who published a series of 10 cases, nearly simultaneously with and independently of Ammich, considered the disease to be infectious and caused by an unknown Giemsa.…”
