Rats were provided both with brain cannulas, to permit infusion of fluids in the ventromedial and lateral hypothalamic areas (resp. VMH and LH), and with two heart catheters. In this way infusions of fluids and withdrawal of blood could...

Fat burners are a category of nutritional supplements that are claimed to increase the metabolism and promote greater energy expenditure, leading to weight loss. However, little is known about the side effects on gastrointestinal motility. In this study, we...

Sympathetic overactivity prevails over the vascular amplifier phenomena in a chronic kidney disease rat model of hypertension.

Physiological reports

Ameer OZ, Hildreth CM, Phillips JK.
PMID: 25413325
Physiol Rep. 2014 Nov 20;2(11). doi: 10.14814/phy2.12205. Print 2014 Nov 01.

We examined whether increased sympathetic nerve activity (SNA) accounts for enhanced depressor responses to ganglionic blockade in the Lewis polycystic kidney (LPK) model of chronic kidney disease (CKD) or whether it reflects increased vascular responses to vasodilation (vascular amplifier)....

Monitoring the Secretory Behavior of the Rat Adrenal Medulla by High-Performance Liquid Chromatography-Based Catecholamine Assay from Slice Supernatants.

Frontiers in endocrinology

De Nardi F, Lefort C, Bréard D, Richomme P, Legros C, Guérineau NC.
PMID: 28993760
Front Endocrinol (Lausanne). 2017 Sep 25;8:248. doi: 10.3389/fendo.2017.00248. eCollection 2017.

Catecholamine (CA) secretion from the adrenal medullary tissue is a key step of the adaptive response triggered by an organism to cope with stress. Whereas molecular and cellular secretory processes have been extensively studied at the single chromaffin cell...

Discriminative stimulus effects of the nicotine antagonist mecamylamine in rats.

Journal of psychopharmacology (Oxford, England)

Garcha HS, Stolerman IP.
PMID: 22290370
J Psychopharmacol. 1993 Jan;7(1):43-51. doi: 10.1177/026988119300700108.

The discriminative stimulus effects of the nicotine antagonist mecamylamine have been investigated to characterize further its behavioural effects and its interactions with (-)-nicotine. Rats were trained to discriminate the effects of mecamylamine from saline in a two-bar operant conditioning...

PMID: 22135597
Malays J Med Sci. 2011 Jul;18(3):18-26.

BACKGROUND: Terminalia chebula Retz is traditionally used to relieve constipation. The current study was performed to investigate the pharmacological action of aqueous extract of Terminalia chebula seeds (ATC) in vitro and in vivo.METHODS: Terminal pieces of rat ileum were...

Effect of intrathecal administration of ET-1, ET-3 and ET(16-21) on blood pressure and micturition reflex in anesthetized rats.

Neurochemistry international

Giuliani S, Lecci A, Maggi CA, Rovero P, Giachetti A.
PMID: 20504743
Neurochem Int. 1991;18(4):565-9. doi: 10.1016/0197-0186(91)90157-9.

In urethane-anesthetized rats, intrathecal administration of endothelin-1 (ET-1), endothelin-3 (ET-3) (3-100 pmol/rat) or the C-terminal hexapeptide ET(16-21) (10-100 nmol/rat) dose-dependently increased mean blood pressure (MBP) and suppressed the supraspinal micturition reflex (SMR). ET(16-21), at 100 nmol, produced a pressor...

The stress of immobilization in water caused a significant increase in the activity of choline acetyltransferase (CAT) and acetylcholinesterase (AChE), acetylcholine (ACh) content in the stomach and gastric acid secretion, but a decrease of choline content in rats. The...

Enhanced sympathetic activity and cardiac sympathetic afferent reflex in rats with heart failure induced by adriamycin.

Journal of biomedical research
