[The psoic bladder or Boari's knell. 4 cases (author's transl)]

Repairing a pelvic ureter is always an ideal when the kidney above it is still functional. But this operation imposes technical artifices when direct urtero-vesical implantation is not possible. Referring to four cases, the authors show the value of the psoic bladder and compare it with the tubulate vesical strip and vesical bipartition.

[Reference values of pulmonary compliance (author's transl)]

Pulmonary compliance has been measured, using a classical method in 156 healthy subjects aged between 18 and 74 years, breathing spontaneously. Pulmonary compliance (ml-cmH2O-1) was related to height in meters (H) by an allometric relationship such as C = aHb. As b was not significantly different from three, than C/H3 ratio was studied. This ratio was not dependent on age so that it was possible to establish that, in men, C (ml-cmH2O-1) = 36.6 H3 (m) and in women, C (ml-cmH2O-1) = 33.3 H3 (m). These two relationships were significantly different. From these relationships and from reference values of pulmonary volumes, specific pulmonary compliance could be calculated but since confidence limits were very wide, their utilization is limited. Furthermore, it is difficult to apply specific compliance in respiratory impairment.

2,3-Diphosphoglycerate red cell concentration changes during the menstrual cycle in woman

The authors showed that 2,3-DPG red cell concentration (2,3-DPG) WAS SIGNIFICANTLY HIGHER DURING THE LAST WEEK Of the menstrual cycle of five women (1.08+/-0.09 mol-,p;Hb-1) (M +/- 1 SE) THAN DURING THE First part and the last but one week of the cycle (0.86+/-0.04 mol-molHb-1, p less than 0.01). PACO2 was significantly lower during the last week of the cycle (36.3+/-1.3 torr) than during the first part and the last but one week of the cycle(40.1+/-0.8 torr, p less than 0.001). This hypocapnia was due to transient hyperventilation in the second part of the menstrual cycle. 5 men were studied during 4 weeks to determinate control values. No change was observed. The 2,3-DGP mean value (1.10+/-0.01 mol-molGb-1) was not significantly different of the values observed in the women during the last week of the cycle. These results suggest that the 2,3-DPG increase during the last week of the menstrual cylce is problably due to a respiratory alkalosis induced by progesterone secretion.
