Effects of a 24 hour fast were studied in 21 obese children aged 7 to 14 and in 8 controls. Mean blood glucose (BG) during fast dropped more in controls (0.88 to 0.54 g/l) than in obese (0.90 to 0.63 g/l) Plasma cortisol changes were similar in the 2 groups, FFA increased (p less than 0.01) in the 2 groups, but the 24 hour mean level was higher in controls (4.0 mEq/l) than in obese (2.06 mEq/l). At the end of the fast, a ketonuria was present in all obese children except 2. Serum alanine dropped similarly in obese (28 to 24 muM p. cent ml) and in controls (30 to 22 muM p. cent ml). All obese exhibited at the end of the fast a significant rise (p less than 0.01) of branched chain aminoacids, not observed in controls. Responses to glucagon (0.03 mg/kg I.M.) were studied before and after fast. At time 0, BG response was higher and more prolonged in obese in spite of hyperinsulinism. At time 24 hours, BG raised from 0.50 to 0.74 g/1 and insulin from 8 to 35 muU/ml in controls, while in obese BG raised from 0.63 to 1.06 g/l and insulin from 25 to 88 muU/ml. Concomitant hyperinsulinsim and biological criteria of hypoinsulinism demonstrated in obese children the peripheral resistance to insulin. The contrast between a normal degree of protein gluconeogenesis and a reduced rate of fat mobilization during fast may be a major biological feature of obesity in childhood.

Three groups of freshly calved dairy cows suffering from fatty liver syndrome of different stages were examined for serum cholic acid (SCA) levels to assess the value of SCA-determination as a diagnostic approach to fatty liver syndrome. A. Comparison of the SCS levels between cows with and without ketonuria: Cows with ketonuria (n = 13) and with elevated plasma ASAT activity, indicating a moderate liver damage, showed a rise of their mean SCA level to 35.3 (+/- 14.9) mumol/l. Freshly calved cows without ketonuria (n = 10) had at the same time a mean SCA level of 17.9 (+/- 6.4) mumol/l, falling practically into the physiological range. The SCA level increased above the physiological range in 10 of the 13 cases with ketonuria, in seven of them even more than twice. B. Interrelationship between SCA level and hepatic lipid content: Increase in hepatic total lipid (TL) was always associated with SCA-elevation. The mean SCA level was 55 (+/- 22.0) mumol/l in cases of severe fatty liver (TL = 200-280 g/kg), and 39.5 (+/- 6.0) mumol/l in the moderate form (TL = 180-200 g/kg) of the syndrome. C. Peripartal SCA levels of cows with fatty liver: Clinically healthy cows (n = 6) with ketonuria and an elevation of serum ASAT and FFA concentrations had a mean SCA level of 35-45 mumol/l. One cow of this group, which developed acute fatty liver syndrome and died within the period of study, showed an extreme SCA level of 100 mumol/l in it's terminal stage.(ABSTRACT TRUNCATED AT 250 WORDS)
