ABSTRACT
We report a 37-year-old man with portal cavernoma who developed pericardial effusion two weeks following sclerotherapy for esophageal varices. It responded to conservative management.

Rhythmometric analysis of hydrolytic enzymes of mouse kidney has been performed on circadian time scale using the F test. Significant rhythms were detected in glucose-6-phosphatase (G6Pase), inorganic pyrophosphatase (InPPase) and alkaline phosphatase (AlPase) on protein and fresh weight basis. Acrophase (time for peak activity) of G6Pase, InPPase and AlPase per mg protein was at 9.9 degrees (1.0 hr), 88.5 degrees (6.0 hr) and at 342.3 degrees (20 hr) respectively. ATPase, which did not show significant rhythm (mean +/- SD = 4.51 +/- 0.30), had a peak value at 32.1 degrees (2.14 hr) with an amplitude of 0.31 units on protein basis. However, G6Pase and AlPase oscillated with high amplitudes (0.18 and 0.71) across the mean value (mesor) of 0.68 +/- 0.3 and 1.43 +/- 0.46 units respectively and with a phase shift of 5 hr. Since G6Pase is a multicomponent and multifunctional enzyme having several overlapping enzyme activities (viz. InPPase), coordinated events of G6Pase, InPPase and ATPase in the regulation of daily renal functions have been mapped in the intact animals, along a physiologic time scale.

Rhythmometric analysis of a group of phosphohydrolases in mouse liver has been performed along a single 24 hr time scale. The presence of the rhythm was conducted by F test. Statistically significant circadian rhythm was detected in glucose-6-phosphatase (G6Pase) and inorganic pyrophosphatase (InPPase) activity expressed on fresh weight and protein basis. Both G6Pase and InPPase oscillated with a high amplitude of 0.44 U and 1.15 U respectively across the mean value (mesor) of 0.40 +/- 0.42 U and 2.81 +/- 1.14 U per mg protein and with a phase shift of 80 degrees (5.34 hr) among them. On the other hand, alkaline phosphatase (AlPase) did not show any rhythm whereas adenosine triphosphatase (ATPase) showed rhythmic activity on protein basis and oscillated across mesor of 1.84 +/- 0.5 U with an amplitude of 0.52. Acrophase (time for peak activity/mg protein) of G6Pase, InPPase and ATPase was found at 194.2 degrees (13.34 hr), 114.1 degrees (8.0 hr) and at 306.1 degrees (20.4 hr) respectively. AlPase, though did not show significant rhythm, had peak value at 231.8 degrees. Since hepatic G6Pase is a multicomponent and multifunctional enzyme with several overlapping activities (viz. InPPase), coordinated action of G6Pase and InPPase in the regulation of hepatic cell functions has been suggested.
