Testosterone therapy for human immunodeficiency virus-positive men with and without hypogonadism.

This study was designed to evaluate the safety and effectiveness of testosterone therapy for clinical symptoms of hypogonadism (low libido, low mood, low energy, loss of appetite/weight) in human immunodeficiency virus-positive men with CD4 cell counts less than 400 cells/mm3 and deficient or low normal serum testosterone levels. The trial consisted of 8 weeks of open treatment with 400 mg of intramuscular testosterone cypionate biweekly. Responders were maintained at this dosage for another 4 weeks and then were randomized in a double-blind, placebo-controlled, 6-week discontinuation trial.

Fluoxetine treatment for depression in patients with HIV and AIDS: a randomized, placebo-controlled trial.

Objective: The goals of this study were to determine whether fluoxetine is superior to placebo in treating HIV-seropositive patients with major depression or dysthymia or both, whether severity of immunosuppression is associated with treatment response, and whether fluoxetine treatment is associated with change in immune status as measured by CD4 cell count.

Method: A double-blind, randomized, placebo-controlled 8-week trial of fluoxetine was conducted in a university-affiliated research outpatient clinic. The fluoxetine-placebo randomization was 2:1.

Smoked cocaine self-administration in females and voucher incentives for abstinence.

Unlabelled: There are three purposes for this study: (1) To extend the laboratory study of heavy smoked cocaine use to women, (2) to assess cocaine withdrawal symptoms and (3) to assess the utility of voucher incentives for achieving and maintaining cocaine and other drug abstinence in female cocaine abusers.

Methods: Ten non-treatment seeking female cocaine smokers resided inpatient for 4-5 days and could smoke up to 6 doses of cocaine base (50 mg each) twice a day (at 1200 h and again at 1600 h) for 2 consecutive days. During the following 2-week outpatient phase, women were given US $40 in merchandise vouchers if urinalysis indicated lower drug levels from the previous day.

Ethanol and food pellet self-administration by baboons.

During daily 23-h sessions, baboons had concurrent access to food pellets and an oral ethanol/dextrose solution. The effect of increasing the fixed-ratio or "cost" for pellets on pellet and fluid intake was examined when baboons had access to 2%, 4%, or 8% (w/v) ethanol. Increasing the response requirement for a pellet decreased pellet intake.

Effects of methysergide and loratadine on food intake, mood, and performance of humans living in a residential laboratory.

The effects of loratadine, a peripherally acting histamine (H1) antagonist, and methysergide, a serotonin (5-HT) antagonist, were evaluated in seven normal-weight, male research volunteers, participating in a placebo-controlled, double-blind, 17-day residential study. Participants received oral loratadine (10 or 20 mg), methysergide (4 or 8 mg), or placebo at 1000 and 1700 hours daily. Active drug was administered on Days 4, 5, 7, 8, 11, 12, 15, and 16; placebo was administered on all other days.

Effects of acute and chronic ethanol exposure on fatty acid ethyl ester synthases in mouse cerebellar membranes.

Fatty acid ethyl esters (FAEE), the products of esterification of fatty acids with ethanol (EtOH), are shown to cause organ injury in chronic alcohol abusers. Their formation is catalysed by the enzyme FAEE synthase which is present in both animal and human brain. In the present study, we investigated the effects of acute and chronic EtOH exposure on FAEE synthase activity in crude cerebellar membrane preparation of mice, using oleic, linoleic and arachidonic acids as substrates.

A novel protocol for studying food or drug seeking in rhesus monkeys.

The purpose of this study was to determine if multiple aspects of drug and food-reinforced behavior could be measured in a single study. Drug or food seeking can be observed under four conditions: 1) internal drug or food cues and external stimulus cues present; self-administration, 2) only internal cues present; priming, 3) no internal or external stimulus cues present; abstinence, and 4) no internal cues, but external stimulus cues present; extinction. Six adult rhesus monkeys lived in three-chambered enclosures: fluid (0.

Behavioral and subjective effects of DN-2327 (pazinaclone) and alprazolam in normal volunteers.

DN-2327 (pazinaclone) is a new non-benzodiazepine compound which has high affinity for benzodiazepine receptors. The acute behavioral effects and abuse liability of DN-2327 (2, 4 and 8mg) were compared to those of the benzodiazepine anxiolytic alprazolam (0.25, 0.

PERSONALITY FEATURES AND DISORDER IN THE SUBJECTS IN THE NEW YORK HIGH-RISK PROJECT.

One hundred and seventy-five offspring of parents in two psychiatrically ill groups and of normal controls in the New York High-Risk Project (NYHRP) were assessed for Axis II personality traits and disorders as defined by the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised (DSM-III-R). These offspring include: subjects at high risk for schizophrenia (HRSz, n = 48), all of whom have a parent with schizophrenic disorder; subjects at high risk for affective disorder (HRAff, n = 40), all of whom have a parent with affective disorder; and subjects at no increased risk for psychiatric illness (NC, n = 87), whose parents are psychiatrically normal. The trained interviewers, who administered a standardized direct interview, were blind to parental clinical status and to previous clinical status of the offspring.

Arachidonate incorporation into phospholipids in rat brain: A comparison between slice and membrane preparation.

The incorporation of [(3)H]arachidonic acid ([(3)H]AA) into cerebral phospholipids was studied in slices and membranes of rat brain cortex. Effects of preincubation, different washing procedures with or without bovine serum albumin, or incubation in the presence of neurotransmitters were investigated. Over 60% of the phospholipid-bound [(3)H]arachidonic acid was recovered in phosphatidylinositol in both slice and membrane preparations.

Atropine Sulfate Premedication and Cardiac Arrhythmia in Electroconvulsive Therapy (ECT).

Prophylactic effects of atropine sulfate as a premedication for cardiac arrhythmia were studied in 44 patients receiving electroconvulsive therapy in a randomized, cross-over, double-blind design. Cardiac rhythms were recorded with Holter monitors during atropine sulfate and placebo treatments. Vagal arrhythmia seemed to be reduced with atropine sulfate premedication, but the frequency of ventricular arrhythmia was not affected.

Idiopathic precocious puberty in girls: Psychosexual development.

A promising model syndrome for the examination of the role of physical maturation in the development of female sexuality is idiopathic precocious puberty (IPP). In this first controlled study of psychosexual development in IPP females, 16 females between 13 and 20 years of age with a history of IPP were compared to 16 control subjects with a history of normal puberty pair-matched to the index subjects on the basis of sex, race, age, socioeconomic level, and menarcheal status. The psychosexual history and the current psychosexual status were assessed by a systematic half-structured interview.
