Factors predicting cancer detection in biopsy of the prostatic fossa after radical prostatectomy.

Objectives: To determine whether the results of anastomotic biopsy for prostate-specific antigen (PSA) recurrence after radical prostatectomy could be predicted by either PSA, PSA velocity, digital rectal examination (DRE), transrectal ultrasound (TRUS), or the interval from prostatectomy to biopsy.

Methods: TRUS with biopsy of the anastomosis was performed for 91 postprostatectomy patients who had either an abnormal DRE or detectable PSA (greater than 0.2 ng/mL).

Cardiovascular depressant effects of N-methyl- and N-isobutyl-1,2-diphenyl ethanolamines: elucidation of the mechanisms of action.

The cardiovascular effects of N-methyl-1,2-diphenyl ethanolamine (compound M) and N-isobutyl-1,2-diphenyl ethanolamine (compound E) were examined in anaesthetized rats and their effects were compared with those of verapamil and diltiazem. Administration of compound M (10-80 mumole/kg), compound E (2-16 mumole/kg), diltiazem (1.5-24 mumole/kg) or verapamil (1.

Antiaggregatory activity of N-methyl- and N-isobutyl-1,2-diphenyl ethanolamines in rat platelets.

The ability of N-methyl-1,2-diphenyl ethanolamine (compound M), N-isobutyl-1,2-diphenyl ethanolamine (compound E), diltiazem and verapamil to inhibit in vitro ADP-induced platelet aggregation was examined in rat platelet-rich plasma. Pretreatment of the platelets with the compounds (0.1-3 mM) for 3 min at 37 degrees C, inhibited an ADP-induced aggregation in a concentration-dependent manner.
