Acute effects of acetylsalicylic acid on renal and hepatic function in normal humans.

The effect of a single oral dose (1 g) of acetylsalicylic acid (ASA) on renal function and hepatic enzymes as well as prothrombin time was studied in two series of experiments on normal human volunteers. Radioimmunoassay of albumin and beta 2-microglobulin excretion rates in urine revealed a statistically significant increase in both beta 2-microglobulin and albumin excretion rates within 2 h after dosage. Hepatic enzymes were not influenced by a single dose of ASA, while a statistically significant reduction in prothrombin time was registered.

Renal effects of chronic exposure to organic solvents. A clinical controlled trial.

Chronic effects of organic solvents on renal function were measured by creatinine clearances and urinary excretion rates of beta 2-microglobulin and albumin. Forty-three male printing trade workers occupationally exposed to different organic solvents for 9-25 years were compared with 43 age-matched male controls. No differences were found either in creatinine clearances or average basal levels of beta 2-microglobulin and albumin excretion rates, whereas a positive relation could be demonstrated between alcohol consumption on the day before the trial and urinary excretion rate of albumin.

Renal effects of acute exposure to toluene. A controlled clinical trial.

Urinary excretion rates of beta 2-microglobulin and albumin were measured in 43 male printing trade workers and 43 age-matched male controls before and during exposure to toluene, 382 mg/m3, for 6 1/2 hours in a climate chamber. There were no significant changes in renal excretion rates of albumin and beta 2-microglobulin during toluene exposure indicating that no causal relationship exists between moderate exposure to organic solvents and renal injury.

Systemic availability of acetylsalicylic acid in normal men and women and its effect on in vitro platelet aggregability.

The systemic availability of acetylsalicylic acid (ASA) after oral ingestion of 1 g in an effervescent formulation was 16.3 +/- 2.0% and 16.

Systemic availability of acetylsalicylic acid in human subjects after oral ingestion of three different formulations.

Systemic availability of acetylsalicylic acid (ASA) in normal human subjects after oral ingestion of 1 g in three different formulations was determined by using high-pressure liquid chromatography for ASA assay. For an effervescent, a plain and a sustained release preparation systemic availabilities expressed in percent of the ingested dose were 16.9 +/- 3.

178 fatal cases of pulmonary embolism in a medical department.

The diagnosis of pulmonary embolism was established during a 6-year period in 284 patients hospitalized in medical departments of a general hospital. Of the 183 patients who died, 178 were autopsied. A retrospective study was performed on the autopsy-verified fatal cases to correlate their clinical state to relevant postmortem findings.

Antihypertensive effect of atenolol (100 mg once a day) and methyldopa (250 mg thrice a day). A double-blind cross-over multicentre study.

In a double-blind cross-over multicentre study lasting for 16 weeks, the antihypertensive effect of atenolol (100 mg once a day) was compared with that of methyldopa (250 mg thrice a day) in 48 patients with mild to moderately severe hypertension. At the end of the trial, atenolol was superior to methyldopa in achieving clinically relevant BP levels, less than 150/95 mmHg (p less than 0.001), and in respect to patients' drug preference (p less than 0.
