anorexia/ニコチン

Male rats on a 22-h food deprivation schedule were injected daily with a low dose of nicotine and allowed to drink sweetened milk for 10 min in a test cage in the colony room. Nicotine initially suppressed milk intake but complete tolerance developed within 10 days so that the amount of intake did

Hypothalamic pro-opiomelanocortin (POMC) neurons are the major source of anorectic melanocortin peptides in the brain. A recent study (Mineur et al., 2011) demonstrates that nicotine directly stimulates arcuate POMC neurons through nicotinic acetylcholinergic α3β4 receptors, suggesting a new

BACKGROUND Nicotine reduces body weight by reducing appetite. Estradiol modulates food intake. Menopause or ovariectomy (Ovx) increases food intake and body weight. Nicotine and estradiol individually influence hypothalamic dopamine (DA) and serotonin (5-HT), whose interaction influences food intake

BACKGROUND A high frequency of cigarette smoking has been reported among individuals with major depression. In a previous study, transdermal nicotine produced short-term improvement in the mood of depressed patients. This study was undertaken to determine the effects of 4 days' administration of

Anxiety may play a role in the initiation of smoking and there is evidence to suggest that sex and age may predetermine responses to nicotine. At present, the greatest increase in smoking is in women and it is often accompanied by dieting. The purpose of the present study was to investigate how the

BACKGROUND Patients with anorexia nervosa can develop distal vasculopathy sometimes leading to severe Raynaud's phenomenon or acrocyanosis. We report a cas of anorexia nervosa-related vasculopathy associated with iatrogenic injury to the radial artery that led to digital necrosis. METHODS An

This is an addictovigilance report of a pregabalin use disorder case in a young female patient who secondarily presented a tobacco use disorder after smoking initiation combined with pregabalin intake. Pregabalin was first prescribed for anxiety. Concomitant use of pregabalin with tobacco led to a

Inflammation contributes to the pathogenesis of cancer anorexia-cachexia syndrome. Nicotine administration reduces cytokine levels and mortality during sepsis. Therefore, nicotine administration may result in improved anorexia-cachexia. Sixteen male Fischer rats inoculated with MCA sarcoma were

People with attention-deficit/hyperactivity disorder (ADHD) or other psychiatric disorders show high rates of nicotine dependence (ND). This comorbidity might be (partly) explained by shared genetic factors. Genetic correlations between ND and ADHD (or other psychiatric disorders) have not yet been

While nicotine treatment to rodents causes a transient anorexia and persistent weight loss, withdrawal produces hyperphagia and weight gain. Herein, we test the hypothesis that endogenous anorectic peptide cocaine- and amphetamine-regulated transcript (CART) may be involved in these nicotine

Rats chronically treated twice daily with nicotine (0.4 mg/kg, SC) or d,1-amphetamine (1.5 mg/kg, SC) exhibited different patterns of anorexia, hypodipsia, and body weight loss. Amphetamine-treated rats developed tolerance to these ingestive effects and to weight loss, whereas nicotine-injected rats

We investigated the role of corticotropin-releasing factor type 2 (CRF(2)) receptors in acute, chronic and withdrawal effects of nicotine on feeding behavior in rats. Nicotine was injected intraperitoneally, whereas CRF, CRF(2) receptors agonist urocortin-1 or selective antagonist astressin2-B were

Daily nicotine injections for 6 weeks produced a transient anorexia with a concomitant reduction of the body weight. Upon nicotine withdrawal, the rats developed a compensatory hyperphagia and gained nearly control weight.

This paper describes the explanatory model of green tobacco sickness (GTS) held by migrant and seasonal farmworkers in North Carolina and compares it with a research-based biobehavioral model. GTS is a form of acute nicotine poisoning that affects individuals who work in wet tobacco fields. It is

(--)-Nicotine, in doses of 0.2-0.6 mg/kg intraperitoneally (i.p.), induced a dose-dependent anorexia 1 h, 2 h and 4 h after food presentation in 20-h food-restricted male rats. The anorectic response of nicotine (0.4 mg/kg, 30 min before the test) was prevented by pretreatment with the central
