ABSTRACT
Blood lactate level was determined in two groups of athletes consisting of 12 male runners and 13 male swimmers. Before their performances, blood lactate level was 1.51 + 0.35 mM/L and within 5 minutes after 400 metre speedy running and 100 metre speedy swimming the levels had risen to 13.07 + 2.98 and 12.71 + 2.11 mM/L. Blood lactate level decreased within 30 minutes after exercise and the level were analysed under 3 different resting condition: oxygen inhalation, normal saline solution ingestion, and normal resting, were 5.68 + 1.49, 5.26 + 1.68, and 6.3 + 1.63 mM/L, respectively. There was no statistically significant difference in blood lactate level between the two groups of athletes, and among the three condifions of resting. These data suggest that workload done by 400 metre speedy running is equivalent to 100 metre speedy swimming. Oxygen inhalation or saline solution ingestion after exercise does not cause any better benefit to blood lactate removal than normal resting.
ABSTRACT
Serum angiotensin converting enzyme (ASCE) has some clinical values, especially in sarcoidosis. The activity of the enzyme in serum is thus determined in healthy adults and new borns as a reference value. There was no difference between sexes in any group. The mean value in 167 adults, aged from 15 to 50 years was 36.3 + 9.6 units/ml, but the suggested reference value was 35.2 + 9.8 units/ml. for 107 persons, aged 18 to 30 years and for which risks and underlying disorders are naturally smaller than for other groups.
ABSTRACT
Serum gamma-glutamyl transpeptidase (gamma-glutamyl transferase EC 2.3.2.2) and alkaline phosphatase (EC 3.1.3.1) activities from 115 adults with various hepatic diseases were compared to 200 normal adults. Although the values of both enzymes are significantly above normal in the same liver disorders, the first enzyme is much more sensitive in liver cirrhosis. The two enzymes are correlated very well (r = 0.648, p < 0.0005) in hepatic patients.
