Circulating immune complexes in pre-eclampsia.

Serum samples from 20 non-pregnant women, 30 women with normal pregnancy and 50 women with pregnancy associated with pre-eclampsia were tested for circulating immune complexes using the polyethyleneglycol precipitation method. A highly significant positive correlation was found between circulating immune complexes and severe pre-eclampsia (BP greater than 140/90 mm Hg, albuminuria greater than 0.25 g/l). In contrast to this the difference in immune complex levels between non-pregnant subject, normal pregnancy cases and patients with mild pre-eclampsia was not statistically significant. A significant positive correlation was found between the level of circulating immune complexes and the severity of albuminuria. These findings suggest that circulating immune complexes, though not seeming to play an aetiological role in pre-eclampsia may very well be involved in its pathogenesis.

Effect of salbutamol on premature labour.

Salbutamol, a beta-adrenergic stimulant, with a property of smooth muscle inhibition has been used in prevention of premature labour on 40 patients. To 540 ml of 5% dextrose solution 5 mg of salbutamol was added. The infusion was started at the rate of 10 drops per minute and then increased by 10 drops every 5-10 minutes, until uterine contractions ceased. It was observed that in 62.5% patients pregnancy was prolonged for more than 7 days and in 80% for more than 3 days. The mean gain in days was 14.8 days and the maximum was 48 days. The drug was more effective in patients with cervical dilatation less than 2 cm and with uterine contractions less than 3 per 10 minutes.

Hemorrhagic hypotension and the lung: in vitro respiration.

We examined the O2 consumption and respiratory quotient of lung slices from rats whose mean blood pressure was decreased to approximately 40 mm Hg for 1 hour by hemorrhage and from control rats that were handled in the same manner but were not bled. The in vitro O2 consumption of lung slices from the hypotensive rats was lower than the O2 consumption of slices from control rats; exogenous glucose did not alter these differences. In the absence of exogenous glucose, the (mean +/- SE) respiratory quotient of lungs from control rats was 0.75 +/- 0.01; from hypotensive rats 0.78 +/- 0.01 (P less than 0.05). Glucose increased the respiratory quotient of lung slices from control rats to 0.95 +/- 001 but increased the respiratory quotient of slices from hypotensive rats to only 0.86 +/- 0.01. We concluded that hemorrhagic hypotension decreases lung O2 consumption and alters substrate metabolism by the lung.
