    Notes: Abstract Visceral leishmaniasis (kala-azar) affecting HIV-infected patient is being reported in increasing frequency. A 40-year-old German bisexual patient with full-blown AIDS is described who presented with Kaposi's sarcoma, epigastric pain, diarrhea, and weight loss but without fever.Leishmania amastigotes were initially found in biopsies from stomach, duodenum, and a cutaneous Kaposi's sarcoma lesion but were later also recovered from bone marrow and lymph node. The patient received three courses of a combination of pentavalent antimony and interferon-γ. In addition to the common side effects such as fever, thrombocytopenia, and elevated amylase and lipase, a vivid progression of the Kaposi's sarcoma was noted. Tumor progression was temporally closely associated with treatment with interferon-γ. Because this phenomemon has also been observed in other patients, we advise caution when using interferon-γ in patients with Kaposi's sarcoma.

    Description / Table of Contents: Zusammenfassung Bei normotensiven und renal hypertensiven Ratten, die kochsalzarm oder kochsalznormal ernährt wurden, wurde der Effekt des Cyclooxygenasehemmers Indomethacin (3,4 mg/kg/24 h) auf den systolischen Blutdruck und die Plasma-Renin-Aktivität untersucht. Indometacin reduzierte die Plasma-Renin-Aktivität in kochsalzarm und kochsalznormal ernährten, normotensiven und hypertensiven Tieren. Darüberhinaus erniedrigte Indomethacin den systolischen Blutdruck in salz-arm ernährten Ratten, erhöhte jedoch den Blutdruck in salz-normal ernährten Tieren. Diese Befunde lassen vermuten, daß der Effekt von Indomethacin auf den Blutdruck von Ratten vom Extrazellulärvolumen und der Plasma-Renin-Aktivität abhängt.
    Notes: Summary The effect of the cyclooxygenase inhibitor indomethacin (3.4 mg/kg/24 hr) on systolic blood pressure (PB) and plasma-renin-activity (PRA) was evaluated in normotensive and renovascular hypertensive rats receiving either a normal or low salt diet. Indomethacin reduced PRA in normal and hypertensive animals on both low and normal salt intake. Indomethacin furthermore, decreased BP in animals on low sodium diet but increased PB in sodium repleted rats. These data suggest that the effect of indomethacin on rat BP may depend on the state of extracellular volume and PRA.
