I worked with Arthur Grollman for 3Vi years (and 12 scientific publications) beginning in 1947. Arthur was Chairman of the Department of Experimental Medicine, and I became Chairman of the Department of Pathology at Southwestern Medical School in Dallas. Grollman inoculated me with his concept of a "nonexcretory antihypertensive function of the kidney", "incretory" he termed it. For some time, ...

INTRODUCTION Robot-Assisted Single Site Radical Nephrectomy (RASS-RN) has been reported by surgeons in Europe and United States (1-3). To our best knowledge this video presents the first RASS-RN with concomitant cholecystectomy performed in Latin America. CASE A 66 year-old renal transplant male due to chronic renal failure presented with an incidental 1.3cm nodule in the upper pole of the ri...

Antihypertensive polar renomedullary lipid (APRL), a conglomerate of 1-0-alkyl-2-acetoyl-glycero-3-phosphocholine analogs, ws tested in 4- to 6-week-old spontaneously hypertensive (SHR) and normotensive Wistar-Kyoto (WKY) rats using microcirculatory techniques. APRL (0.5 ug/ml), when added to the solution bathing the cremaster muscle, caused significant changes in the diameter, red blood cell v...

The purpose of these experiments was to investigate whether the vasodilator tissue hormone bradykinin contributes to the maintenance of normal blood pressure. A newly synthesized peptide competitive antagonist of bradykinin, the compound Arg-Pro-Hyp-Gly-Phe-Ser-DPhe-Phe-Arg-trifluoracetic acid (B3852), capable of inhibiting the depressor effect of exogenous bradykinin by over 50%, was infused i...
