Krebs Henseleit Buffer

1. Rat kidney cortex slices were incubated for 30 min at 37°C in unmodified Krebs-Henseleit buffer containing aldosterone, vasopressin, theophylline, ethacrynic acid, frusemide, spironolactone or ouabain. 2. Tamm—Horsfall glycoprotein (THG) released into the media was measured by radioimmunoassay and at the end of each experiment the slices were homogenized and assayed for THG content. 3. Incubation of kidney cortex slices in unmodified buffer resulted in a significant increase in the slice THG content when compared with pre-incubation levels. The increase was prevented by puromycin or cycloheximide. 4. Incubation in ethacrynic acid (1 mmol/l) or frusemide (10 mmol/l) resulted in a significant increase in release of THG when compared with unmodified buffer. Puromycin or cycloheximide failed to prevent the increased release. 5. THG release induced by ethacrynic acid or frusemide is probably the result of an aggregation-disaggregation reaction on the cell membrane. It is suggested that the action of the chloride inhibiting diuretics, ethacrynic acid and frusemide, is mediated in some way via THG.

Orientation of rat renal and intestinal brush-border membrane vesicles was studied with two independent methods: electron-microscopic freeze-fracture technique and immunological methods. With the freeze-fracture technique a distinct asymmetric distribution of particles on the two membrane fracture faces was demonstrated; this was used as a criterion for orientation of the isolated membrane vesicles. For the immunological approach the accessibility or inaccessibility of aminopeptidase M localized on the outer surface of the cell membrane to antibodies was used. With both methods we showed that the brush-border membrane vesicles isolated from rat kidney cortex and from rat small intestine for transport studies are predominantly orientated right-side out.
