Ontogeny of isoproterenol-stimulated renin secretion from sheep renal cortical slices.

The American journal of physiology

Nakamura KT, Page WV, Sato T, Klinkefus JM, Robillard JE.
PMID: 2500035
Am J Physiol. 1989 Jun;256(6):R1258-63. doi: 10.1152/ajpregu.1989.256.6.R1258.

The ontogeny of renin secretion from renal cortical slices was studied in two groups of fetal (107-109 days of gestation and 131-136 days of gestation; term is 145 days), newborn (3-9 days old), and adult nonpregnant sheep. Isoproterenol (ISO;...

Effect of enantiomers of propranolol on desipramine-induced anti-immobility in the forced swimming test in the rat.

Pharmacological research

Mancinelli A, D'Aranno V, Stasi MA, Lecci A, Borsini F, Meli A.
PMID: 2047359
Pharmacol Res. 1991 Jan;23(1):47-50. doi: 10.1016/s1043-6618(05)80105-7.

The effect of d- and l-enantiomers of propranolol on desipramine-induced anti-immobility effects and on brain desipramine levels was studied in the rat. Intraperitoneal propranolol and desipramine were administered three times, 25, 6, 2 and 24, 5, 1 h respectively,...

[Endogenous beta-adrenomimetic substance as a constituent of the adrenergic beta receptor blocking mechanism].

Akusherstvo i ginekologiia

Pomaskin IN, Medvedev BI, Tsirkin VI, Zakharov VV.
PMID: 2554739
Akush Ginekol (Mosk). 1989 Aug;(8):23-7.

In order to reveal endogenous beta-adrenomimetic in the blood the authors proposed the biological testing of the serum and plasma on the isolated myometrium of the rat. For this purpose obsidan was used as a beta-adrenoblocker. It was shown...

Inhibition of phosphatidic acid phosphohydrolase activity by sphingosine. Dual action of sphingosine in diacylglycerol signal termination.

FEBS letters

Lavie Y, Piterman O, Liscovitch M.
PMID: 2269371
FEBS Lett. 1990 Dec 17;277(1):7-10. doi: 10.1016/0014-5793(90)80796-l.
Free Article

Recent evidence indicates that a major fraction of diacylglycerol that is produced in hormonally stimulated cells arises by phosphatidylcholine hydrolysis via the sequential action of phospholipase D and phosphatidic acid phosphohydrolase (PAP). We have previously reported that sphingoid bases...

Beta-adrenergic and prostanoid inhibition of canine fundic mucosal mast cells.

The American journal of physiology

Soll AH, Toomey M.
PMID: 2468293
Am J Physiol. 1989 Apr;256(4):G727-32. doi: 10.1152/ajpgi.1989.256.4.G727.

We examined regulation of histamine release from canine hepatic and fundic mucosal mast cells in short-term culture. We found that beta- but not alpha-adrenergic agonists markedly inhibited concanavalin A (ConA)-stimulated histamine release. Inhibition by epinephrine was reversed by the...

Role of atrial natriuretic peptide in hemoconcentration during exercise.

American journal of hypertension

Tsai RC, Yamaji T, Ishibashi M, Takaku F, Hsu ST, Yeh SJ, Lee YS.
PMID: 2148091
Am J Hypertens. 1990 Nov;3(11):833-7. doi: 10.1093/ajh/3.11.833.

Changes in plasma levels of atrial natriuretic peptide (ANP) and albumin, and blood hematocrit (Hct) during treadmill exercise were studied in 6 healthy men before and after beta-adrenergic blockade. Plasma ANP levels increased during exercise and then gradually decreased....

The influence of propranolol on the cardiovascular effects and plasma clearance of epinephrine.

Anesthesia progress

Ichinohe T, Igarashi O, Kaneko Y.
PMID: 1842159
Anesth Prog. 1991 Nov-Dec;38(6):217-20.
Free PMC Article

The purpose of the present study was to determine how propranolol modifies the circulatory effects of epinephrine infused to produce plasma concentrations achieved during dental local anesthesia and to evaluate the effects of propranolol on the plasma clearance of...

The neutrophil respiratory burst. Responses to fatty acids, N-formylmethionylleucylphenylalanine and phorbol ester suggest divergent signalling mechanisms.

European journal of biochemistry

Hardy SJ, Robinson BS, Poulos A, Harvey DP, Ferrante A, Murray AW.
PMID: 1646722
Eur J Biochem. 1991 Jun 15;198(3):801-6. doi: 10.1111/j.1432-1033.1991.tb16084.x.
Free Article

The oxygen-dependent respiratory burst is a key neutrophil function required for the killing of bacteria. However, despite intensive investigation, the molecular events which initiate the respiratory burst remain unclear. Recent reports have suggested the agonist-induced hydrolysis of cellular phosphatidylcholine...

Effects of canine endotoxin shock on lymphocytic beta-adrenergic receptors.

Circulatory shock

Silverman HJ, Lee NH, el-Fakahany EE.
PMID: 1963122
Circ Shock. 1990 Dec;32(4):293-306.

To determine whether beta-adrenergic receptors on circulating lymphocytes are impaired during endotoxemia and the precise role of catecholamines in this process, we allocated 16 dogs to three groups: I) control-saline vehicle (n = 5), II) endotoxin--Escherichia coli endotoxin 1.0...

Effects of diltiazem or propranolol during exercise training of hypertensive men.

Medicine and science in sports and exercise

Stewart KJ, Effron MB, Valenti SA, Kelemen MH.
PMID: 2355813
Med Sci Sports Exerc. 1990 Apr;22(2):171-7.

This was a prospective, randomized, double-blind, placebo-controlled trial to establish whether beta blockers or calcium-channel blockers limit exercise capacity and training responses in men with mild hypertension. Circuit weight and aerobic training was used to assess the effects of...

Autonomic mechanisms underlying area postrema stimulation-induced cardiovascular responses in rats.

The American journal of physiology

Ferguson AV, Smith P.
PMID: 1677538
Am J Physiol. 1991 Jul;261(1):R1-8. doi: 10.1152/ajpregu.1991.261.1.R1.

Experiments were designed to examine the autonomic mechanisms underlying the decreases in blood pressure and heart rate elicited by electrical stimulation in the rat area postrema (AP). Vagotomy was found to significantly reduce the bradycardia observed in response to...
