Blood carbon dioxide tension changes during hysteroscopy. | During hysteroscopy the uterus may be distended with carbon dioxide (CO2), nitrous oxide (N2O), or Hyskon (a high molecular weight dextran). An initial study in 27 patients (group 1) using arterialized venous blood samples demonstrated rises in carbon dioxide tension (PCO2) when N2O was insufflated by using a laparosco... | 467,700 | [

Effects of cadmium on polyribosome sedimentation pattern in mouse liver. | Cadmium injected to mice provokes an acute disaggregation of hepatic polyribosomes. The effect appears within 15 min, it is maximal after 1 h and then gradually disappears. The reaggregation of polyribosomes takes place 6--12 h after injection. The disaggregation of polyribosomes is linear with log doses in a range of ... | 467,771 | [

Retention of plasma somatomedin activity in the foetal rabbit following decapitation in utero. | One rabbit foetus within each litter was decapitated in utero on day 24 of gestation. Plasma somatomedin activity and costal cartilage metabolism were studied 5 days later in the experimental foetuses and control litter-mates. Somatomedin was assayed by the uptake of [35S]sulphate in vitro into costal cartilage from in... | 469,459 | [
