noradrenaline/vomiting

The emetic action of noradrenaline was investigated in unanesthetized cats, after it was injected into the cerebral ventricles through chronically implanted cannulae. Intracerebroventricular injection of noradrenaline produced dose-dependent and shortlasting emesis, which was abolished after

Sila-substitution of drugs (the carbon/silicon switch) is a concept that is being successfully used for the development of new chemical entities. The (R)-sila-analogue of the antidepressant venlafaxine is devoid of the serotonin reuptake inhibition observed with the marketed drug, leading to a

The relation between pretreatment night-time urinary catecholamine excretion and chemotherapy-induced nausea and vomiting was studied. The first cohort included 17 women and three men with various cancer forms receiving low or moderately emetogenic chemotherapy. The second cohort included 42 women

The chemotherapeutic drug cisplatin is associated with severe gastrointestinal toxicity that can last for several days. A recent strategy to treat the nausea and emesis includes the combination of a 5-HT3 receptor antagonist, a glucocorticoid, and an NK1 receptor antagonist. The present studies

1. Intravenously injected cisplatin at a dose of 4 mg kg(-1) induced early and delayed emesis in all pigeons without occurrence of lethality during a 72 h observation period. The early emetic response occurred with a latency of 81.3+/-8.0 min (n=15) and reached a peak at 2 - 3 h, and decreased

Intracerebroventricular injection of dopamine (0.5-4.0 mg) produced dose-dependent and short-lasting emesis (1-8 min) in cats, which was abolished after ablation of the area postrema. Relatively selective alpha 2-adrenoceptor antagonists (yohimbine and idazoxan) and a mixed alpha 1- and alpha

Despite the postulated tumour affinity of Lipiodol is liver dysfunction after chemoembolization of hepatic malignancies common. Vasoconstricting action of noradrenaline to protect non malignant tissue was studied. 70 patients with unresectable HCCs (UICC IV: 61%) were treated via percutaneous

1 The hypothermia produced by intraventricular injections of thyrotropin releasing hormone (TRH) in unanaesthetized cats has been investigated. 2 TRH is more potent than either noradrenaline or calcium ions. It is estimated that the equi-potent molar ratio for TRH: noradrenaline:calcium is

In unanaesthetized cats the biochemical mechanisms and the functional characteristics of the emetic action of injection of noradrenaline and McN-A-343, a ganglionic muscarinic stimulant into the cerebral ventricle (i.c.v.) through chronically implanted cannulae were investigated. Both produced

The involvement of 5-hydroxytryptamine (5-HT) with cisplatin-induced emesis in the ferret was investigated using reserpine, para-chlorophenylalanine and fenfluramine. Pretreatment with reserpine (5 mg/kg, 24 hr), fenfluramine (5 mg/kg, 4 days) or para-chlorophenylalanine (100 or 400 mg/kg, 4 days)

A clinical study was conducted to investigate the relationship between nausea/emesis after chemotherapy for lung cancer (docetaxel 60 mg/m(2), cisplatin 80 mg/m(2)) and blood serotonin (S), blood catecholamine (adrenaline) (A), noradrenaline (NA) and dopamine (D) in effective and non-effective

The antiemetic and emetic actions of the anticancer drug cyclophosphamide injected intracerebroventricularly (i.c.v.) and intravenously (i.v.) through chronically implanted cannulae were investigated in unanaesthetized cats. Cyclophosphamide in single doses was injected into the cerebral ventricles

Phenylephrine is recommended for the management of hypotension after spinal anaesthesia in women undergoing caesarean section. Noradrenaline, an adrenergic agonist with weak β-adrenergic activity, has been reported to have a more favourable haemodynamic profile than phenylephrine. However, there are

Basic guidelines for cancer pain treatment can be found in many different handbooks published in the last years. Particularly those of the World Health Organisation published in 1986 and revised in 1996, furnish useful indication for cancer pain treatment. The authors therefore focused on resuming
