It is shown that total cholesterol levels in the blood before and immediately after delivery in obese and normal weighing women remain within normal values. Conversely blood triglycerides levels, higher than normal prior to delivery, are shown to drop back to normal values within three days (p 0.001). This is not thought to be attributable to labor stress.
Serum glycerol and NEFA content variations are examined before and after labor in obese and normal weighing women (35 subjects). Blood glycerol and NEFA are shown to increase before delivery. Glycerol values are shown to drop to normal immediately after delivery, while NEFA values diminish to a lesser extent. Statistical analysis shown that blood glycerol increase could be pregnancy-dependent in both normal weighing and obese women, but that NEFA increase could be pregnancy-dependent in normal weighing women only. Obesity increases blood glycerol and NEFA concentration considerably, thus masking the effects of pregnancy.
Blood PA and RBP content were estimated in 100 normal subjects (50 men and 50 women). Mean values of 28.2 and 3.75 mg/dl were ascertained for PA and RBP, respectively. The molar ratio RBP/PA was calculated as 0.31 +/- 0.05. Serum concentrations of PA and RBP are seen to be sex-dependent (20% higher in males). Hyperthyroid subjects exhibit a decrease in the two vitamin A-binding proteins whereas no modification could be revealed for hypothyroid states. In patients on maintenance hemodialysis mean serum PA and RBP concentrations were remarkably higher than normal, whereas liver cirrhotic subjects showed a highly significant depression of mean serum RBP and PA values.

Constipation frequency was investigated among 1897 subjects (874 males and 1023 females), ranging in age from 6 to 70 years, chosen at random between city inhabitants and farmers. Bowel habit was studied in 966 obese patients (390 males and 576 females). The authors followed for the diagnosis of constipation either the commonest and restrictive criterion of the weekly bowel actions or the clinical one which implies also others parameters, like hard or small stools, difficulties of expulsion or feeling of incomplete evacuation after defecation. The statistical analysis showed that constipation frequency is 8.3% in obese patients and 1.5% in normal-weighting, according to weekly bowel actions criterion: the difference is statistically significative (p less than 0.001).
The authors studied the behaviour of blood glycerol concentration after glycerol i.v. infusion in obese and normal subjects. The aim of research was to clarify the meaning of blood glycerol increase observed by some one in obese subjects. Results obtained showed that in obese subjects there is not any abnormal behaviour of blood glycerol concentration after infusion and that in none of patients studied was observed any significative increase of basal blood glycerol concentration values.
