A combination of pharmacological and genetic approaches was used to determine the role of type 4 cAMP-specific cyclic nucleotide phosphodiesterase 4 (PDE4) in reversing alpha(2)-adrenoceptor-mediated anesthesia, a behavioral correlate of emesis in non-vomiting species. Among the family-specific PDE
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
Both interferon-alpha (IFN-alpha) and alpha-difluoromethylornithine (DFMO) have shown modest activity as single-agent therapy in the treatment of malignant melanoma. Several investigators have demonstrated true synergism in vitro of the combination of DFMO and IFN-alpha against human tumor cells,
OBJECTIVE
This study seeks to evaluate the comparative role of alpha-fluoromethylhistidine and diphenhydramine in the prevention of motion sickness.
METHODS
The role of histaminergic mechanisms in motion sickness were evaluated in a feline model. Twenty-six female cats were studied. A variety of
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
Pentostatin (2'-deoxycoformycin) is a unique antineoplastic agent that has proven valuable in the treatment of a number of lymphoid malignancies. Dose-limiting toxicities observed in clinical trials include central nervous system (CNS) effects and acute renal failure. Information regarding the
A pair of siblings with clinical symptoms of cyclic vomiting and ketoacidosis were found to have a biochemical triad of normoglycemia, ketoacidosis and elevated levels of alpha-hydroxy- and alpha-aminobutyrate in plasma and urine. Methionine loading studies in both sibs produced prompt rises in
Tick bites can cause the alpha-gal syndrome, which is characterized by delayed anaphylactic reactions mainly to red meat and offal due to IgE antibodies against mammalian galactose-alpha-1.3-galactose carbohydrate (alpha-gal). Ixodes ricinus bites are considered the primary cause of IgE antibody
Though therapeutic advances have been made in the treatment of ovarian carcinoma, success at achieving a cure in women with advanced disease has been elusive. Since advanced ovarian carcinoma is frequently confined to the peritoneum, the use of intraperitoneal (IP) chemotherapy is being studied.
This paper describes a rare case of adenocarcinoma located in the middle portion of the esophagus with liver metastasis. An 80-year-old man was admitted to our hospital with dysphagia and vomiting, following which an upper gastrointestinal series and esophagoscopy located an elevated-type carcinoma
Prostaglandins are mainly used in clinical medicine for midterm abortion and to terminate pregnancy. Systemic adverse reactions include nausea and vomiting, which occur in approximately half of the patients and, to a lesser extent, diarrhea. Although bronchospasm occurs infrequently, PGF2 should be
The dosage of Prostaglandin F2 alpha used until the present (100, 250 and 1000 micrograms/kg bw), in order to treat pyometra in the bitch, was accompanied with side effects such as salivation, vomiting and diarrhea. In the present work, the efficiency of low dose Prostaglandin (20 micrograms/kg bw)
A case is presented involving an acute fatality resulting from self-administered alpha-chloralose, a rodenticide. A 18-year-old man was found dead at home, with several stains of vomit on the carpet. An empty box of three bags of 5 g 100% alpha-chloralose (Corbeaux nuisibles, Rhône Poulenc) was
BACKGROUND
Malignant mesothelioma is a tumour which is generally resistant to chemotherapy. While the addition of interferon to chemotherapy improves response rates in some other malignancies, such a combination has not been evaluated in the treatment of mesothelioma.
OBJECTIVE
To assess the
