Abstract
OBJECTIVE We investigated whether perimenopausal menstrual cycle irregularity is associated with increased gonadotropin immunoactivity, bioactivity, or the bioactivity/immunoactivity ratio at baseline and after short-term stimulation with gonadotropin-releasing hormone. STUDY DESIGN Subjects consisted of four groups: (1) young regular cycling women (< 35 years old), older women (> 35 years) with (2) regular or (3) irregular menstrual cycles, and (4) postmenopausal women. Gonadotropin-releasing hormone stimulation tests (100 micrograms intravenous gonadotropin-releasing hormone) were performed in the National Institute of Mental Health outpatient clinic during the follicular phase of the menstrual cycle or randomly in postmenopausal women. RESULTS Perimenopausal women had baseline follicle-stimulating hormone and luteinizing hormone levels and stimulated follicle-stimulating hormone levels (area under the curve) that were similar to those of postmenopausal women and significantly greater than those of control (younger and older) women. Postmenopausal women had significantly greater baseline levels of luteinizing hormone bioactivity than did the other three groups. The bioactivity/immunoactivity ratio in the postmenopausal women was significantly greater than those in the perimenopausal and older cycling women, which were similar. No change in the bioactivity/immunoactivity ratio was seen after gonadotropin-releasing hormone stimulation in any group. CONCLUSIONS Although the perimenopause is associated with increases in baseline and stimulated gonadotropin levels similar to those seen after the menopause, significantly increased baseline luteinizing hormone bioactivity and the bioactivity/immunoactivity ratio are seen only after the menopause.

Abstract
OBJECTIVES This article defines androgens (and anabolic steroids), describes their mechanisms of action, and summarizes their behavioral effects and relevance in animals and humans. METHOD A MEDLINE-derived review of the literature on androgens and behavior was performed; pivotal earlier publications were also obtained and included in the review. RESULTS In animals, the effects of androgens on brain structure and function are well-established and profound, with behavioral implications extending far beyond reproduction. Androgens play a prominent role in the organization or programming of brain circuits, which are subsequently activated by gonadal steroids. In humans, roles for androgens have been described, albeit inconsistently, in the regulation of sexuality, aggression, cognition, emotion, and personality. The relevance of androgens for psychiatry is further suggested by gender-related differences in pharmacokinetics/pharmacodynamics and in the prevalence, course, and treatment response characteristics of several psychiatric disorders. Direct psychoactive effects of exogenously administered androgens have been described for many years, most recently in reports of the psychotoxic effects of anabolic steroids. CONCLUSIONS Data from both animals and humans suggest that the biological and behavioral responses to androgens are context-dependent.

Abstract
Because of the unique combination of physical (e.g. bloating, water retention) and psychological (e.g. mood, memory) symptoms associated with premenstrual syndrome (PMS), various hypothalamic and pituitary hormones have been implicated in the pathophysiology of PMS. We measured plasma adrenocorticotropic hormone (ACTH), arginine vasopressin (AVP) and atrial natriuretic peptide (ANP) across the menstrual cycle in 19 women with PMS and 12 normal women. AVP concentrations were lower throughout the menstrual cycle in symptomatic PMS patients compared with PMS patients during asymptomatic cycles and normal women. No differences in ACTH and ANP were observed between patients and controls. However, ACTH and ANP were positively and significantly correlated with each other in women with PMS but not in controls. These findings contribute to a growing list of menstrual cycle-independent findings in women with PMS and suggest that there may be an underlying neurobiological vulnerability that predisposes some women to experience somatic and mood dysregulation in the luteal phase of the menstrual cycle.

Abstract
The current laboratory approach to assessing magnesium status is based on determining the concentration of total Mg ((Mg)) in serum or plasma. This strategy is problematic in that the amount of Mg in blood is less than 1% of total body Mg and does not accurately reflect (Mg) in other tissues. Furthermore, the (Mg) of blood does not distinguish biologically active, ionized Mg from the bound fraction. The goal of this study was to determine intracellular ionized Mg ((Mg++)i) of skeletal muscle in vivo and to compare results with the (Mg) of blood constituents. (Mg++)i was determined in resting skeletal muscle by using phosphorus 31 magnetic resonance (31P-MR) spectroscopy. (Mg) was measured in serum (S(Mg)), serum ultrafiltrate (UF(Mg)), mononuclear blood cells (MBC(Mg)), and red blood cells (RBC(Mg)) by using atomic absorption spectroscopy or a colorimetric assay. In a sample of 60 healthy adult subjects, skeletal muscle (Mg++)i = 557 +/- 97 mumol/L (mean +/- SD); S(Mg) = 0.78 +/- 0.09 mmol/L; UF(Mg) = 0.60 +/- 0.12 mmol/L; MBC(Mg) = 13.8 +/- 2.3 mmol/L; and, RBC(Mg) = 1.92 +/- 0.33 mmol/L. A significant negative correlation was found between (Mg++)i and S(Mg) (r = -0.43, p < 0.05). S(Mg) was significantly lower (p < 0.05) and (Mg++)i significantly higher (p < 0.05) in women than in men, but neither was related to age. These findings provide new insight into the relationship between blood Mg measures and (Mg++)i of the largest soft tissue mass of the human body.

Abstract
OBJECTIVE The hormonal regulation of magnesium (Mg) metabolism is poorly understood. Preliminary evidence suggests that reproductive hormones may influence Mg concentrations in various tissues. The purpose of this study was to determine if Mg concentrations in blood and muscle are affected by the phase of the menstrual cycle. METHODS Magnesium measures were obtained from 16 women over the course of one complete menstrual cycle. The principal outcome measure was intracellular ionized Mg ([Mg++]i) in skeletal muscle as measured by 31P nuclear magnetic resonance spectroscopy. Three blood measures (serum, red blood cell, and mononuclear blood cell) of total Mg ([Mg]) were also obtained. RESULTS Mean Mg concentrations were stable across the menstrual cycle with no evidence of a menstrual cycle phase effect for any of the measures. Furthermore, skeletal muscle [Mg++]i was not correlated with any blood measure of [Mg]. CONCLUSION These results suggest that physiologic fluctuations in reproductive hormones do not influence either blood [Mg] or skeletal muscle [Mg++]i in healthy, regularly cycling women.

Abstract
Groups of rats were treated with buspirone (1 mg/kg/day) for 21 days using osmotic minipumps implanted subcutaneously. After buspirone treatment, the 5-HT1A receptor mRNA levels were significantly decreased in the CA1 and CA2 of the hippocampus, but were markedly increased in the dentate gyrus (DG), CA3 and CA4. The level of the 5-HT1A receptor binding sites was not significantly changed in these subhippocampal areas. Buspirone treatment markedly increased 5-HT2A receptor mRNA levels in the DG, CA2, CA3 and CA4. This was accompanied by a significant increase in the level of 5-HT2A receptor binding sites in all subhippocampal regions. These results demonstrate that chronic buspirone treatment differentially regulates 5-HT1A and 5-HT2A receptor mRNA as well as their expressed binding sites in various regions of the hippocampus.

Abstract
Preliminary evidence suggests that nimodipine, an L-type calcium channel blocker, is effective in treating some patients with rapidly cycling affective disorders and some phases of Alzheimer's disease, i.e., two syndromes associated with transient or permanent reductions in cerebrospinal fluid (CSF) somatostatin, respectively. CSF somatostatin (SRIF) was measured in 14 affectively ill patients while they were medication-free and during chronic nimodipine treatment. CSF somatostatin significantly increased in patients during active nimodipine treatment compared with ones in the medication-free state. The current findings raise the possibility that nimodipine-induced increases in CSF somatostatin could potentially contribute to its spectrum of efficacy on neuropsychiatric disorders associated with cognitive or affective impairment. Further clinical and preclinical studies are indicated to elucidate the potential mechanisms involved in the elevation of CSF SRIF, whether it is reflected in regional changes in brain, and its possible relevance to nimodipine's clinical actions.

Abstract
The levels of 3 alpha-hydroxy-5 alpha-pregnan-20-one (allopregnanolone) and the epimeric 3 alpha-hydroxy-5 beta-pregnan-20-one (pregnanolone) were studied in women with prospectively confirmed premenstrual syndrome (n = 15) and in a group of asymptomatic control women (n = 12) during the luteal phase of the menstrual cycle. Single late luteal phase plasma samples were selected to make comparisons of plasma hormone levels between patients and controls in the following measures: allopregnanolone, pregnanolone, the ratio of allopregnanolone to pregnanolone, the ratio for each of these anxiolytic steroids to the parent compound progesterone, and the ratio of the sum of allopregnanolone and pregnanolone to progesterone. Differences in these measures were compared by analysis of variance. Additionally, correlations were performed among the various hormone measures and between the hormone measures and the symptom self-ratings. Analysis of variance showed no significant between group differences in the plasma levels of allopregnanolone, pregnanolone, and progesterone. Plasma levels of both allopregnanolone and pregnanolone were correlated with plasma progesterone levels. However, there were no significant correlations between the severity of mood and behavioral symptoms and plasma levels of progesterone, allopregnanolone, and pregnanolone. These data suggest that symptoms of premenstrual syndrome are not associated with a simple deficiency state of either progesterone or its anxiolytic steroid metabolites.

Abstract
The purpose of this article is to review the literature on the effects of the menstrual cycle on dependent variables in mood disorder research to inform investigators which physiological measures are likely to be significantly affected by menstrual cycle fluctuations and precisely how they might be affected. The following variables are discussed: prolactin; growth hormone; the hypothalamic-pituitary-thyroid axis (including thyrotropin, triiodothyronine, and thyroxine); the hypothalamic-pituitary-adrenal axis (cortisol, corticotropin, and beta-endorphin); melatonin; sleep; body temperature; and neurotransmitter activity (serotonergic and adrenergic systems). Body temperature and plasma and urinary norepinephrine vary predictably over the menstrual cycle. Prolactin and beta-endorphin may have peaks in the periovulatory phase, whereas serotonin levels in platelet-poor plasma may reach a nadir at that time. Triiodothyronine, thyroxine, cortisol, and melatonin do not appear to vary systematically over the course of the menstrual cycle, whereas the data for growth hormone, thyrotropin, corticotropin, and sleep are inconclusive.

Abstract
BACKGROUND This study examined the effect of long-term (mean, 19 months) treatment with clomipramine hydrochloride on cerebrospinal fluid (CSF) levels of several neuropeptides and monoamine metabolites in children and adolescents with obsessive-compulsive disorder. METHODS The CSF levels of corticotropin-releasing hormone, vasopressin, somatostatin, and oxytocin and of the monoamine metabolites 5-hydroxyindoleacetic acid, homovanillic acid, and 3-methoxy-4-hydroxyphenylglycol were measured in 17 children and adolescents with obsessive-compulsive disorder before and after long-term treatment with clomipramine. RESULTS Treatment resulted in significant decreases in CSF levels of corticotropin-releasing hormone (mean +/- SD, 175 +/- 32 vs 152 +/- 25 pmol/L, P < .03) and vasopressin (mean +/- SD, 1.30 +/- 0.57 vs 0.86 +/- 0.54 pmol/L, P < .02) and a trend toward a decrease in somatostatin levels (mean +/- SD, 21.3 +/- 8.5 vs 15.3 +/- 9.8 pmol/L, P < .06). Treatment also significantly increased CSF oxytocin levels (mean +/- SD, 6.05 +/- 1.60 vs 6.70 +/- 1.44 pmol/L, P < .01). Significant changes in CSF monoamine metabolite levels with treatment included significant decreases in CSF levels of 5-hydroxyindoleacetic acid (mean +/- SD, 109 +/- 31 vs 77 +/- 23 pmol/mL, P < .001), CSF homovanillic acid (mean +/- SD, 273 +/- 111 vs 237 +/- 101 pmol/mL, P < .04), and 3-methoxy-4-hydroxyphenylglycol (mean +/- SD, 42.4 +/- 10.2 vs 36.1 +/- 4.8 pmol/L, P < .02) and a significant increase in the homovanillic acid-5-hydroxyindoleacetic acid ratio (mean +/- SD, 2.44 +/- 0.46 vs 3.42 +/- 0.84, P < .0001). CONCLUSIONS These neuropeptide results coupled with evidence that central administration of corticotropin-releasing hormone, vasopressin, and somatostatin to laboratory animals increases arousal and acquisition of conditioned behaviors whereas central administration of oxytocin has opposite behavioral effects are consistent with a role for these neuropeptides in the pathophysiologic processes and pharmacologic treatment of obsessive-compulsive disorder.

Abstract
The purpose of this study was to evaluate blood magnesium (Mg) measures across the menstrual cycle in women with premenstrual syndrome (PMS) and control women. Longitudinal determinations of plasma, red blood cell (RBC) and mononuclear blood cell (MBC) Mg were made in 26 women with prospectively confirmed PMS and in a control group of 19 women. Data were analyzed using analysis of variance with repeated measures and Spearman rank correlations. Significant diagnostic group effects were observed for RBC and MBC Mg concentrations (p < 0.05). These effects reflected lower Mg concentrations in PMS patients at each sampling time. No significant effects were observed for either plasma Mg or MBC Mg content, nor were there significant time by diagnosis effects for any of the measures. Consistent with earlier studies, we found decreased RBC Mg concentrations and additionally observed decreased MBC Mg concentrations in women with PMS. However, neither of these relative deficits were confined to the luteal phase.

Abstract
There has been recent renewed interest in the role of magnesium in affective disorder, particularly in the bipolar subtype. However, determinations of serum magnesium concentrations have not yielded consistent findings and little is known about cerebrospinal fluid (CSF) magnesium in these patients. We analyzed CSF magnesium levels from 173 medication-free patients with affective disorder (76 bipolar I, 54 bipolar II, and 43 unipolar) and 59 healthy volunteers. In addition, we examined CSF magnesium from 32 patients before and during carbamazepine treatment and 13 patients before and during lithium treatment. CSF magnesium levels varied significantly according to gender (with lower concentrations in women) but not with respect to age, diagnosis, mood state, or treatment with carbamazepine or lithium. An abnormality of magnesium in affective disorders, if it exists, is not readily detectable in CSF.

Abstract
Dissociation is made manifest by a failure to integrate thoughts, feelings, memories, and actions into a unified sense of consciousness. Although dissociation is presumed to be a special state of consciousness manifested by state-dependent memory and physiology, the psychobiology of dissociation is poorly understood. In this study, we examined cerebrospinal fluid levels of the major monoamine metabolites and beta-endorphin in patients with eating disorders (11 with anorexia nervosa, 16 with bulimia nervosa), while they were acutely ill. Dissociative capacity was measured using the Dissociative Experiences Scale (DES). We provide evidence that neurochemical changes in dopaminergic, serotonergic, and opioid systems may be associated with the clinical expression of dissociation in patients with eating disorders during the acute phase of their illness. These preliminary results are compatible with previous studies of neurochemical disturbances in the eating disorders and suggest that future work in dissociation should specifically include examination of these neurobiologic systems.

Abstract
OBJECTIVE To evaluate the acute effects of anabolic steroids on mood and behavior in male normal volunteers. DESIGN A 2-week, double-blind (subject and rater), fixed-order, placebo-controlled crossover trial of methyltestosterone. SETTING An inpatient research unit at the National Institutes of Health. SUBJECTS A volunteer sample of 20 men who were medication free, free of medical and psychiatric illness, not involved in athletic training, and had no prior history of anabolic steroid use. INTERVENTION A sequential trial for 3 days each of the following four drug conditions: placebo baseline, low-dose methyltestosterone (40 mg/d), high-dose methyltestosterone (240 mg/d), and placebo withdrawal. MAIN OUTCOME MEASURES Mood and behavioral ratings were completed during each drug condition and included both subjective and objective measures. RESULTS Significant (P < .05) albeit subtle increases in symptom scores were observed during high-dose methyltestosterone administration compared with baseline in positive mood (euphoria, energy, and sexual arousal), negative mood (irritability, mood swings, violent feelings, and hostility), and cognitive impairment (distractibility, forgetfulness, and confusion). An acute manic episode was observed in one of the 20 subjects, representing a 5% incidence, even under these conservative conditions. An additional subject became hypomanic. Baseline characteristics including family psychiatric history or previous drug abuse did not predict symptom changes. CONCLUSION This is the first placebo-controlled prospective study demonstrating the adverse and activating mood and behavioral effects of anabolic steroids.

Abstract
OBJECTIVE To evaluate the efficacy of alprazolam in the treatment of premenstrual syndrome. DESIGN A randomized, double-blind, placebo-controlled, crossover trial of alprazolam during eight menstrual cycles. SETTING Outpatient clinic at the National Institute of Mental Health, Bethesda, Md. PARTICIPANTS Twenty-two women with prospectively confirmed premenstrual syndrome entered this study. All subjects were either self-referred or were referred by their physicians. All reported having regular menstrual cycle lengths, were taking no medication, and were free of current or recent medical or psychiatric illness. Two subjects did not complete the trial. INTERVENTION Participants were assigned to receive alprazolam or placebo as follows: cycle 1, 0.25 mg of alprazolam or placebo three times daily beginning on menstrual cycle day 16; cycle 2, 0.50 mg of alprazolam or placebo three times daily according to the regimen during the first cycle; cycles 3 and 4, 0.75 mg of alprazolam or placebo three times daily from menstrual cycle day 16 and continued throughout the fourth menstrual cycle to evaluate the efficacy of relatively long-term (approximately 6 weeks) treatment with alprazolam. MAIN OUTCOME MEASURES Daily self-report symptoms ratings were completed during the entire study period. RESULTS We observed no significant differences in the severity of premenstrual symptom ratings during alprazolam administration compared with placebo on any scale except the Beck Depression Inventory Scale. The Beck Depression Inventory ratings demonstrated a statistically (F1,19 = 7.1, P < .05), but not clinically, significant improvement in depressive symptoms during alprazolam administration compared with placebo. CONCLUSION Our findings do not support alprazolam as a uniformly effective treatment for the symptoms of premenstrual syndrome.

Abstract
UNLABELLED We have examined the relationship between thyroid function and the presence of symptoms in women with prospectively confirmed premenstrual syndrome (PMS) in the following ways: 1) basal thyroid function tests (n = 124); 2) thyroid auto-antibody levels (n = 63); 3) TRH stimulation tests performed during the follicular phase (n = 39) or during both the follicular and luteal phase (n = 21); and 4) the efficacy of L-T4 in the treatment of PMS (n = 30). RESULTS Thirteen women (10.5%) had basal evidence of either grade I or II hypothyroidism or hyperthyroidism. Elevated thyroid auto-antibody titers were observed in eight women (13%). Eighteen women (30%) (all with normal basal TSH levels) had abnormal responses to TRH, either blunted (n = 6) or exaggerated (n = 12). L-T4 was not superior to placebo in the treatment of PMS in a double blind placebo controlled cross-over trial. Although it is clear that PMS is not simply masked hypothyroidism, abnormalities of stimulated thyroid function appear with greater than expected frequency in women with PMS and may define a subgroup of women with this disorder. L-T4 supplementation appears to have no place in the routine management of PMS.

Abstract
OBJECTIVE Because the central administration of somatostatin to experimental animals produces behaviors with some similarities to the compulsions of patients with obsessive-compulsive disorder and because serotonin reuptake inhibitors have been reported to reduce brain content of somatostatin, the authors examined central somatostatin activity in patients with obsessive-compulsive disorder. METHOD CSF for measurement of somatostatin was obtained from 15 drug-free outpatients with obsessive-compulsive disorder and 27 normal volunteers. RESULTS The mean CSF somatostatin level was significantly higher in the patients with obsessive-compulsive disorder than in the normal subjects. CONCLUSIONS Although the functional significance of this finding is unknown, these data are consistent with a role for somatostatin in the clinical symptomatology of obsessive-compulsive disorder and its response to neuropharmacological agents. The high levels of CSF somatostatin reported here in a patient subgroup whose predominant symptoms consisted of overly focused, perseverative thought processes are in contrast to the consistently low levels of CSF somatostatin seen in patients with a spectrum of disorders characterized by substantial cognitive deficits.

Abstract
Patients with Alzheimer's disease (AD) and major depression have been shown to have overlapping clinical symptoms and biological markers, including decreased concentrations of cerebrospinal fluid (CSF) somatostatin-like immunoreactivity (SLI), which may be related to alterations in the hypothalamic-pituitary-adrenal axis activity. As in prior studies, we found that CSF SLI was significantly decreased in a group of AD patients (N = 49) and a group of elderly patients with major depression (N = 18), as compared with 13 age-matched controls (F[2, 77] = 12.9, p < .001). In the present study, CSF SLI and CSF corticotropin-releasing factor correlated significantly within the group of AD patients (r = 0.49, p < .0004) and almost attained significance in the depressed patients (r = 0.47, p < .07). CSF SLI correlated significantly with urinary free cortisol within each patient group (r = -0.51, p < .03). Clinical measures of dementia severity and depression did not consistently correlate with CSF SLI in either patient group.
