Splenoportovenography: safety, success rate and hemodynamic changes, and incidence and natural history of splenic hematoma

Forty-five non-cirrhotic patients undergoing splenoportovenography (SPV) were studied. SPV was performed successfully in 43 (95.5%) patients. Local pain was encountered in 12 (26.6%) and lasted for a mean (+/- SD) of 7 +/- 3.8 hours. Local tenderness was noted in 17 (37.7%) and lasted for 6.8 +/- 3.7 hours. The mean rise in the pulse rate after the procedure was 6.5 +/- 4.7 beats per minute and the fall in the systolic and diastolic blood pressures was 3.4 +/- 2.5 and 0.8 +/- 1.7 mmHg respectively. Post-SPV splenic hematoma was noted in 3 (6.6%) patients. All were subcapsular, at the site of puncture, and disappeared by the seventh day. There was no difference in the age, change in the pulse rate, and fall in systolic or diastolic blood pressures between those who developed and those who did not develop hematoma. One patient required one unit of blood transfusion. There were no deaths. SPV was noted to be a simple and safe procedure with a high success rate with minimal morbidity and no mortality.

Comparative incorporation of uridine-3H into nucleolar RNA of mouse subcutaneous and skin tissues at early times after 20-methylcholanthrene administration

A single s.c. injection of 20-methylcholanthrene (1 mg in 0.2 ml olive oil) is found to stimulate the relative uptake of uridine-3H by the skin and the s.c. tissue 17- and 3fold respectively, 24 h post-administration.
