Dopaminergic abnormalities in bulimia nervosa have been reported in some studies, but results are not consistent across studies. In the present study, clinical characteristics, plasma level of homovanillic acid (pHVA) and two scales - the Eating Attitudes Test (EAT) and the Beck Depression Inventory
para-Chlorophenylalanine (PCPA, 100-200 mg/kg) was used as a pharmacological tool to characterize the 5-hydroxytryptamine (5-HT) involvement in the emesis occurring 24 hr after the administration of cisplatin (10 mg/kg) in the ferret. PCPA was effective to antagonize the initial 8 hr period of
Cannabis sativa (CS, family Cannabinaceae) has been reported for its anti-emetic activity against cancer chemotherapy-induced emesis in animal models and in clinics. The current study was designed to investigate CS for potential effectiveness to attenuate cisplatin-induced vomiting in healthy
To provide a neurochemical basis for the central nervous system actions of nitrous oxide, the changes of brain dopamine (DA), serotonin (5-HT), norepinephrine (NE), and metabolites of DA and 5-HT were studied in rats. Thirty male Wistar rats were assigned to one of five groups according to the type
A 6-week-old male infant presented with 2 days of fever, emesis, and diarrhea, associated with episodic and chaotic rapid eye movements, determined to be opsoclonus. An electroencephalogram (EEG) obtained during the events was normal. He was treated empirically for meningitis, and an initial workup
Neonatal adrenal abscess is an extremely rare condition. 32 cases, 4 bilateral, have been described in the world literature. We treated successfully other two bilateral cases. We report on this rare condition and review the world literature. In our Department we observed two patients in the neonatal
SCH39166 [(-)-trans-6,7,7a,8,9,13b-hexahydro-3-chloro-2-hydroxy-N-methyl- 5H-benzo[d]naptho-(2,1-b)azepine] is a benzonaphthazepine that has been evaluated as a selective D1 dopamine receptor antagonist. In vitro, SCH39166 (Ki = 3.6 nM) inhibited the binding of [3H]SCH23390 (a D1 specific compound)
The pharmacological properties of AD-5423 [2-(4-ethyl-1-piper-azinyl)-4- (4-fluorophenyl)-5,6,7,8,9,10-hexahydrocycloocta[b]pyridine] were studied in biochemical and behavioral tests. In vitro, AD-5423 bound preferentially to dopamine (DA)-D2 (Ki, 14.8 nM; cf. haloperidol, 8.79 nM; and clozapine,
Tetrahydrobiopterin (BH4) deficiencies are a heterogeneous group of disorders caused by a defect in two of the three enzymes involved in its biosynthesis or in the two recycling enzymes. Except for the deficiency of dehydratase, an enzyme catalyzing a reaction in the recycling pathway, all other
The selectivity, peripheral vs. central actions, of the antidopaminergic agent L-646,462 was assessed in two ways. First, elevation of prolactin in serum (peripheral) and homovanillic acid in the striatum were measured in rats. L-646,462 was found to have a central/peripheral activity ratio of 143,
An 8-yr-old girl is presented who had periodic attacks of vomiting, psychotic depression, drowsiness, and hypertension (160/110 mm Hg) for a period of 16 months after head injury. At the initiation of the attack, serum ACTH and vasopressin levels were prominently increased (610 pg/ml and 41
Varying reactions of the vegetative nerve system to various point combinations (for example: vomiting, dizziness, diarrhea, urge to urinate, fatigue or drowsiness, headache), especially to the needling of Tai Chong (Li 3), induced us to perform biochemical studies before and after acupuncture
The effect of deoxynivalenol (DON, vomitoxin) on brain amine levels was investigated in swine. DON, a trichothecene mycotoxin, causes suppression of feed intake (anorexia) in susceptible species. Following acute administration of DON to pigs (0.25 mg/kg, IV), concentrations of endogenous
Ten patients with severe dementia due to Alzheimer's disease (AD) or multi-infarct dementia (MID) or both, were treated with the precursor amino acids of the neurotransmitters serotonin and dopamine. The precursor amino acids (PAA) were given orally in a preparation that included tyrosine (4 gm
Oseltamivir (Tamiflu), a neuraminidase inhibitor, is effective for treating both seasonal flu and H5N1 influenza A virus infection. Oseltamivir is generally well tolerated, and its most common adverse effects are nausea and vomiting. However, neuropsychiatric behaviors including jumping and falling
