The acute administration of the neurosteroid precursor, progesterone (10 mg/kg, s.c.) produced significant hyperphagia in female mice as observed at 0.5-, 1-, 2- and 3-h time intervals. At this dose progesterone also produced significant increase in immobility period duration in Porsolt's forced swim test and nociceptive response in hot-plate and tail-flick tests. Treatment with direct (quipazine, 5 mg/kg, i.p.) and indirect (fluoxetine, 10 mg/kg, i.p.) acting serotonergic agents per se produced significant hypophagia, decrease in immobility period and induced analgesic effect in hot-plate and tail-flick test. Further, treatment with both fluoxetine (10 mg/kg, i.p.) and quipazine (5 mg/kg, i.p.) significantly reversed progesterone-induced hyperphagia, depression and algesia in the female mice. Pretreatment with seganserin, a 5-HT(2) receptor antagonist (2 mg/kg, i.p.) significantly reversed fluoxetine and quipazine-induced antidepressant and analgesic effects. Seganserin reversed quipazine-induced hypophagia but in a replicate study it failed to reverse fluoxetine-induced hypophagia. Further, seganserin, 2 mg/kg, i.p., significantly reversed the suppressive effect of fluoxetine and quipazine on progesterone-induced hyperphagia, depression and algesia in hot-plate test. Seganserin also reversed the suppressive effect of fluoxetine and quipazine on progesterone-induced algesia in hot-plate test. These data suggest that the modulation of progesterone-induced effects by these serotonergic agents possibly involve 5-HT(2) receptor mechanisms. Further, the study underscores the use of serotonergic agents for the treatment of eating and affective disorders caused by the regular changes or disturbances of ovarian steroid levels in females.

This is a general survey of pertinent topics concerning female sterilization in France in question and answer format. Sterilization is not outdated as a result of modern contraception because now more women desire efficient contraception. There is no French law against female sterilization, but the case for men is not as clear. Examples of gynecologic, obstetrical, medical, genetic, psychosocial, and extramedical indications were listed. 5 types of tubal sterilization and 4 routes were described: mini-laparotomy and celioscopy are popular in France, but colpotomy and the inguinal route are rare. Sterilization is preferred immediately after delivery or in the puerperium. Failures range from 1:2000 for Irving procedure, to a maximum in those sterilized just after delivery. Hysterectomy is not recommended because of risk of neurosis. Tubal sterilization can be reversed in 27-75% of cases. Much discussion was devoted to psychological sequelae of sterilization in French women, such as frigidity, depression, guilt, regret, nervousness, cancerophobia, overeating, some of which occur in half of the patients. These frustrations were blamed on cultural and religious taboos. French physicians were urged not to sterilize women under 30, with fewer than 3 children, of Moslem, Jewish or Catholic faith, with poor acceptance of feminity, excessive maternal instinct, or poor marital adjustment. Male sterilization was not recommended, because the side effects of impotence and depression are unacceptable.

Most depressives suffer from weight loss, anorexia and insomnia, while for winter depressives the typical symptoms are weight gain, carbohydrate craving, overeating, oversleeping and extreme lack of energy. It is important to know whether winter depressives differ from most other depressives on measures of energy regulation. In wintertime, we evaluated the rate of oxygen consumption in relationship to neuro-vegetative depressive symptoms in 92 Siberian women. The seated subjects underwent oxyspirography in the mid-morning (1.5 hours after a standard breakfast). It was found that the oxygen consumption rate was similar in non-depressed women (n = 25) and depressed women with non-seasonal depression (n = 27). The comparatively lower values were obtained in women with winter depression (n = 40). This finding supports the suggestion that the behaviour disturbances typical for winter depression may represent a physiological feedback loop to energy conservation.

Seventy unwed pregnant patients in states of mild to moderate depression evidenced by one or more symptoms (tenseness, "nervousness," crying spells, listlessness, fatigue, nausea and vomiting, insomnia and overeating), received informal psychotherapy and a sustained-release capsule combining d-amphetamine sulfate and amobarbital.Forty-eight patients had complete or substantial relief of symptoms, 15 had partial relief, seven had slight or no relief. Use of the preparation seemed to make tense, "nervous" patients more communicative and amenable to counseling, but was less effective in listless, easily fatigued patients. Because of its direct mood-alleviating action and its ability to facilitate psychotherapy, the d-amphetamine sulfate-amobarbital combination proved a very effective treatment for mild and moderate depression accompanying pregnancy.

The aim of this follow-up study was to evaluate the longer-term effectiveness of guided self-care for bulimia nervosa. In the original trial, 62 patients with DSM-III-R bulimia nervosa were randomly assigned to: a) a self-care manual plus eight fortnightly sessions of cognitive behavioural therapy (guided self-change); or b) 16 weekly sessions of cognitive behavioural therapy (CBT). Twenty-eight of these patients (45% of the original cohort) were involved in this follow-up study based on personal interviews by experts and self-rated instruments; the majority of the others could not be traced, but their pre- and post-treatment variables were not different from those of the follow-up patients. After an average follow-up of 54.2 months (SD 5.8), significant improvements were achieved or maintained in both groups in terms of the main outcome measures: eating disorder symptoms based on expert ratings (Eating Disorder Examination sub-scores for overeating, vomiting, dietary restraint, and shape and weight concerns), self report (Bulimic Investigatory Test Edinburgh), and a global five-point severity scale. There was also an improvement in the subsidiary outcome variables: Beck's Depression Inventory, the Self-concept Questionnaire, and knowledge of nutrition, weight and shape. During the week before the follow-up examination, 66.7% of the patients in the guided self-change group and 61.5% of those in the CBT group had not binged, vomited or abused laxatives. Guided self-change incorporating a self-care manual is an approach that can be as effective as standard cognitive behavioural therapy in the long-term, and can reduce the amount of therapist contact required.

Psychopathological disorders, and depression in particular, are strongly linked to eating attitude in obese patients. The identification of cannabinoid CB1 receptors (CB1Rs) in areas of the central nervous system (CNS) that have been implicated in regulation of mood and food intake suggests that these receptors may mediate such a behavioral link. The goal of this study was to evaluate CB1R modulation of antidepressant-like effects and food intake. For this purpose, 129/SVE and C57BL/6 male mice were acutely dosed intraperitoneally (i.p.) with the CB1R inverse agonist AM251 (3-30 mg/kg) and tested, respectively, in the tail-suspension test (TST) and in the forced-swim test (FST), which have been used widely as tests sensitive to antidepressant compounds. Like the antidepressant desipramine (DMI, 16 mg/kg), AM251 significantly reduced immobility at 10 mg/kg in the TST and at 1 and 10 mg/kg in the FST. Such a decrease of immobility was not accompanied by an increase in motor activity in the open field, suggesting that occupancy of CB1R by AM251 induced antidepressant-like effects. This was supported by two additional experiments. First, the co-administration of the CB1R agonist CP55940, at a dose that did not induce motor impairment or profound hypothermia (0.01 mg/kg), reversed effects of AM251 in the TST. Secondly, effects of AM251 in the FST were absent in CB1R knockout (KO) mice. In addition to an antidepressant-like effect, AM251 reduced fasting-induced hyperphagia over a comparable dose range. Taken together, these data suggest that regulation of mood and food intake might be obtained through inverse agonism of CB1R.

The symbolic characters of the Seven Deadly Sins can be traced from time to time in the cultural history of human mankind, being directly specified in certain artistic products. Such are, among others, the painting entitled "The Seven Deadly Sins and the Four Lost Things" by Hieronymus Bosch and the poems Divina Commedia and The Foerie Queene by Dante Alighieri and Edmund Spenser, respectively. However, there are several paragraphs referring to these behaviours of the Seven Deadly Sins in the Bible and in the dramas of William Shakespeare. The objective of the present review is to propose that dysfunctions in the central serotonergic system might be involved in the neurobiology of these 'sinful' behaviour patterns. Evidences indicate that behaviour traits such as Accidia (Sloth), Luxuria (Lust, Lechery), Superbia (Pride), Ira (Wrath, Anger), Invidia (Envy), Avaritia (Greed, Avarice), and Gula (Gluttony) can relate to the functional alterations of serotonin in the brain. Results of biochemical and molecular genetic (polymorphism) studies on the human serotonergic system (receptor, transporter, enzyme), findings of functional imaging techniques, effects of depletion (or supplementation) of the serotonin precursor tryptophan, data of challenge probe investigations directed to testing central serotonergic functions, alterations in the peripheral serotonin measures (platelet), and the changes in the CSF 5-hydroxy-indoleacetic acid content indicate such serotonergic involvement. Furthermore, results of animal experiments on behaviour change (aggressive, dominant or submissive, appetite, alcohol preference) attributed to serotonin status modification and the clinically evidenced therapeutic efficacy of pharmacological interventions, based on the modulation and perturbation of the serotonergic system (e.g. selective serotonin reuptake inhibitors), in treating the 'sinful' behaviour forms and analogous pathological states reaching the severity of psychiatric disorders (depression, sexual disturbances, social phobia, impulsivity-aggression, obsessive-compulsive and related spectrum disorders, paranoid jealousy, eating disorders) all strongly suggest the possibility that brain serotonin dysfunctions might underlie the neurophysiology of the Seven Deadly Sins.

Depression with atypical features is a treatable and relatively common disorder among depressed outpatients. A growing body of evidence suggests this is a biologically distinct subtype of depression. This assertion is supported by genetic epidemiologic studies and by a preferential response of the subtype to monoamine oxidase inhibitors compared with tricyclic antidepressants. The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) includes atypical features as a parenthetical modifier for depressive illness. According to DSM-IV diagnostic criteria ("atypical features" specifier), the disorder is primarily characterized by 2 or more of the following symptoms as predominant features in patients with major depression or dysthymic disorder: overeating, oversleeping, "leaden paralysis," and interpersonal rejection sensitivity. Patients also show mood reactivity in response to actual or potential positive events. Despite aspects of the disorder resembling a maladaptive, persistent mode of behavior, patients diagnosed with depression with atypical features demonstrate a good response to antidepressant treatment.

Hypericum extract (HE) might be favourably active in depressed patients with reversed vegetative signs (RVS). Therefore, we performed an exploratory subgroup analysis of a three-armed study to compare HE, fluoxetine, and placebo in patients with major depressive disorder (MDD) in a 12 wk trial. A total of 135 patients were randomized to 12 wk treatment with HE LI 160 (900 mg/d), fluoxetine (20 mg/d), or placebo. Patients with RVS were defined in two steps, according to DSM-IV. First, patients with melancholy-related vegetative signs were excluded. Secondly, patients had to have at least one score of 2 for the items 22-26 of the HAMD-28 scale, which are related to hypersomnia and hyperphagia. Twenty-seven patients remained in the group. Analysis of covariance (ANCOVA) was applied using the HAMD-17 score. Secondly a chi2 test for response was performed, using the same and further an adapted criterium as in recently published studies. ANCOVA revealed a trend to a global difference. Post-hoc analysis showed a trend to superiority of HE compared to placebo and to fluoxetine, but a very large effect size for both differences. Fluoxetine was not different from placebo. The adapted response criterium showed a significant global difference as well as a significant superiority of HE over placebo and over fluoxetine. These data are based on a small sample size and must be considered tentative. A characterization of vegetative features of patients with depression could lead to an overall increased effect size in the treatment with HE.

Cancer surgery is a major challenge for patients to develop immune depression in postoperative period. Several cytokines can depress immune cell subpopulations. Increased cytokine response after surgery is assumed to arise mainly from lipooxygenase pathway acting on membrane arachidonic acid. Therefore; investigators focused their efforts to alter the membrane fatty acid profile by changing the nutritional regimen with epsilon-3 fatty acid supplementation and encouraging results were obtained after surgery. Despite the theoretical and clinical advantage of enteral nutrition many surgeons remain committed to parenteral nutrition for feeding of patients due to maintain bowel rest and fear of anastomosis leakage at the postoperative period. Several studies investigating role of the postoperative immunonutrition reported that beneficial immunological changes were associated with reduction of infectious complications. Interestingly; these findings were observed at least five days after the surgery in which the highest incidence of complications was seen. In this prospective study including 42 patients eligible for curative gastric or colon cancer surgery; we investigated the beneficial effect of enteral immunonutrition (EEN) compared to total parenteral hyperalimentation (TPN) beginning from the preoperative period. Cortisol and CRP levels as stress parameters significantly increased one day after surgery in both groups but they rapidly returned to (on POD1) preoperative baseline level in EEN group whereas these values remained high in the TPN group. Additionally a significant decrease in natural killer (NK) cells and CD8+ levels were observed in both groups. However they recovered on POD3 in EEN group and on POD6 in TPN group. CD4+ subset remained almost same as preoperative value in the TPN group whereas it increased from (%) 40.14 to 46.40, 51.29 and 54.7 on PO 6th hr, POD3 and POD6 in the EEN group. Our findings suggest that preoperative nutrition via the enteral route provided better regulation of postoperative immune system restoration than parenteral nutrition. On the basis of our findings we recommend enteral immunonutrition to be started at the preoperative period rather than postoperatively before a major operation whenever the enteral route is feasible.
