1. To further understand the vasodilator actions of atrial natriuretic peptide and its role in hypoxic pulmonary hypertension, we studied the effects of atrial natriuretic peptide in the isolated perfused rat lung during normoxic ventilation and afte

In isolated rat adipocytes, tumour-promoting phorbol esters caused (1) dose-dependent stimulation of lipogenesis in the absence of insulin and (2) inhibition of the lipogenic effect of submaximal concentrations of insulin, but without affecting insul

Histamine secretion and phosphatidylinositol turnover were compared in antigen-sensitized rat peritoneal mast cells stimulated with a number of different ligands. A small and variable increase in the incorporation of [32P]Pi and of [3H]inositol into

Vasopressin stimulates the incorporation of [32P]Pi into phosphatidylinositol but not into other phospholipids in rat thoracic aorta strips. The relative abilities of three vasopressin analogues to stimulate phosphatidylinositol labelling in rat aort

The effect of diarachidonin on the synthesis of prostaglandin E2 in rabbit kidney medulla slices was examined. The addition of diarachidonin stimulated prostaglandin E2 production in a dose-dependent manner. At three concentrations (10, 50 and 100 mi

The effects of verapamil, a calcium antagonist, on lipolysis in isolated rat adipocytes were studied. Verapamil (100 microM) potentiated lipolysis due to dibutyryl cyclic AMP (Bt2cAMP) at submaximal concentrations, with or without extracellular Ca2+.

Treatment of intact hepatocytes with glucagon, TH-glucagon [(1-N-alpha-trinitrophenylhistidine, 12-homoarginine]glucagon), angiotensin or vasopressin led to a rapid time- and dose-dependent loss of the glucagon-stimulated response of the adenylate cy

In hepatocytes from 48 h-starved rats identical glucagon dose-response curves were obtained for the stimulation of gluconeogenesis from lactate, for ketogenesis and for the decreasing of the C5-dicarboxylate pool. Glucagon (20 nM) caused a 5-fold inc

The stimulation of phenylalanine hydroxylation in isolated liver cells by sub-maximally effective concentrations of glucagon (less than 0.1 microM) is antagonized by insulin (0.1 nM-0.1 microM). This phenomenon is a consequence of a decrease in the g

Light-emission of the perfused lung is induced by t-butyl hydroperoxide, giving chemiluminescence yields that oscillate between 800 and 1500 counts/s depending on the site and position of the lung. The response of the perfused lung to infusion with d
