Oral Supplementation with Baker's Yeast Beta Glucan Is Associated with Altered Monocytes, T Cells and Cytokines following a Bout of Strenuous Exercise.

Exercise and physical labor in extreme environmental conditions causes transient decreases in immune cell and cytokine concentrations, likely increasing the susceptibility to opportunistic infection. Baker's yeast beta glucan (BYBG) has been previously demonstrated to be an effective countermeasure in athletes, but its effectiveness in individuals of average fitness under similar physical stress is unknown. The purpose of this study was to determine if 10 days of oral supplementation with BYBG could modify previously observed suppression of monocytes, T cells, circulating and whole blood LPS-stimulated cytokines due to strenuous exercise.

Clinical trials simulation: a statistical approach.

A generic template for clinical trials simulations that are typically required by statisticians is developed. Realistic clinical trials data sets are created using a unifying model that allows general correlation structures for endpoint*timepoint data and nonnormal distributions (including time-to-event), and computationally efficient algorithms are presented. The model allows for patient dropout and noncompliance.

Combined treatment of acute EAE in Lewis rats with TNF-binding protein and interleukin-1 receptor antagonist.

Experimental autoimmune encephalomyelitis (EAE) is a term given to describe a collection of animal models representing the human disease multiple sclerosis (MS). Although not fully understood, the involvement of cytokines and the immune system in either EAE or human MS is well established. Past efforts have shown that inhibition of proinflammatory cytokines tumor necrosis factor (TNF-alpha) or interleukin-1 (IL-1) result in amelioration of acute EAE in Lewis rats.

Effect of zimeldine and its metabolites on [3H]thymidine incorporation in lymphocyte cultures from psychiatric patients with or without a hypersensitivity reaction during zimeldine therapy.

Lymphocyte transformation test (LTT) was applied to 28 patients who had developed a hypersensitivity syndrome (HSS) during treatment with the antidepressant drug zimeldine. Twenty-seven patients treated with zimeldine without any symptom of an HSS were matched controls. Zimeldine and its metabolites norzimeldine and CPP 200 all induced statistically significant increased [3H]thymidine incorporation in cultured lymphocytes from the HSS patients compared with the controls, norzimeldine being the most potent inducer.

Interaction study between remoxipride and biperiden.

Twelve healthy male volunteers took part in a double-blind randomised cross-over study composed of three treatment sessions: remoxipride 100 mg; remoxipride 100 mg plus biperiden 4 mg; and biperiden 4 mg. Plasma and urine concentrations of remoxipride and biperiden, plasma prolactin levels, salivary flow and adverse events were recorded to assess pharmacodynamic interactions. Remoxipride and biperiden had no effect on each other's plasma concentrations.

Neuroendocrine responses to single oral doses of remoxipride and sulpiride in healthy female and male volunteers.

Six female and six male healthy volunteers received 100 mg remoxipride, 200 mg sulpiride and placebo as single oral doses in a double blind trial with a randomized crossover design. The main objective was to compare the effect of the two drugs on serum prolactin levels, but effects on other hormones were also investigated. Remoxipride and sulpiride increased the serum levels of prolactin to similar peak levels.

Drug interaction studies with remoxipride.

The interaction potential of remoxipride was investigated with biperiden, warfarin, diazepam, and ethanol. The studies were conducted in 12 healthy volunteers each of whom received single doses of remoxipride, the interacting drug, and the combination in a randomized crossover design. Remoxipride and biperidene had no influence on each other's pharmacokinetics.

Pharmacokinetics of foscarnet and distribution to cerebrospinal fluid after intravenous infusion in patients with human immunodeficiency virus infection.

To investigate the pharmacokinetics and effects of intravenous foscarnet, 13 relatively healthy male patients with human immunodeficiency virus infection and a mean CD4+ lymphocyte value of 0.45 x 10(-9) cells per liter were given a continuous intravenous infusion of foscarnet (0.14 to 0.

Pharmacokinetics and absorption of foscarnet after intravenous and oral administration to patients with human immunodeficiency virus.

Six patients with human immunodeficiency virus were given foscarnet in oral solution, 4000 mg every 6 hours for 3 days, followed by a washout period for 2 days and continuous intravenous infusion of 16,000 mg/24 hr over 72 hours. After oral foscarnet, plasma concentrations were less than 33 mumol/L in four patients; two had occasional concentrations of 35 to 50 mumol/L. The extent of absorption varied between 12% and 22%.

Intrapleural administration of 0.25%, 0.375%, and 0.5% bupivacaine with epinephrine after cholecystectomy.

Thirty patients who had undergone cholecystectomy (subcostal incision) were randomly allocated to three groups of ten patients each and given intrapleural injections of 20 ml 0.25% (group I), 0.375% (group II), or 0.

Remoxipride--a new potential antipsychotic drug. Pharmacological effects and pharmacokinetics following repeated oral administration in male volunteers.

Remoxipride, a new potential antipsychotic drug, was administered over 4 days at two dose levels, 70 and 140 mg t.i.d.

Pressor response of oral tyramine in healthy men given amiflamine and placebo.

During two baseline challenge tests, oral tyramine (50 to 400 mg) was given to 12 healthy men to find each individual's cardiovascular pressor response. All 12 subjects "tolerated" 200 mg oral tyramine, but three of the 12 developed an increment in systolic blood pressure greater than 30 mm Hg when given a dose of 400 mg. Thereafter, amiflamine, 5 mg bid (n = 8), or placebo, 1 capsule twice a day (n = 4), were given in a double-blind fashion for 7 days, and oral tyramine challenge tests (12.

The effect of adjuvant radiotherapy on the time of occurrence and prognosis of local recurrence in primary operable breast cancer.

A retrospective study was conducted of all patients with an isolated locoregional recurrence of carcinoma of the breast after modified radical mastectomy was performed with or without adjuvant radiotherapy. The findings are summarized as follows: adjuvant radiation therapy delayed the appearance of local recurrence; there was no difference in the length of time to the diagnosis of distant dissemination between the irradiated and nonirradiated patients after the treatment of locoregional relapse. 35% of the irradiated patients and 25% of the nonirradiated patients remained clinically free of disease for relatively long periods after the treatment of locoregional relapse.

Topical treatment of recurrent genital herpes infections with foscarnet.

In a double-blind study 86 patients with a total of 129 episodes of recurrent genital herpes were treated topically with 0.3% foscarnet or placebo cream. All patients considered, healing time was significantly shortened in the foscarnet group as compared to the placebo group (p less than 0.

Immune status of untreated patients with Hodgkin's disease and prognosis.

In this study of 127 previously untreated adult patients with Hodgkin's disease and 167 age- and sex-matched controls, highly purified blood lymphocytes were studied for E+ receptors; their spontaneous DNA synthesis and that induced by concanavalin A, pokeweed mitogen, or purified protein derivative of tuberculin were measured as incorporation of 14C-thymidine. T-cell counts and the response to mitogens and antigen were significantly decreased in the patients, while the spontaneous lymphocyte activity was increased. Forty-nine patients had died after a mean observation time of 6 years.

Blood T-lymphocyte functions in healthy adults in relation to age.

Blood T-lymphocyte functions were studied in 167 healthy adults (age range 19-91 years). Lymphocyte DNA synthesis induced by concanavalin A, pokeweed mitogen and PPD antigen declined with age while the spontaneous DNA synthesis remained essentially unchanged. Relative and total T-cell counts but not total lymphocyte counts were moderately decreased in elderly persons.

Lymphocyte function in untreated Hodgkin's disease: an important predictor of prognosis.

One hundred and twenty seven consecutive and previously untreated patients with Hodgkin's disease (HD) (mean age 47 years) from the Stockholm area admitted to Radiumhemmet, Karolinska Hospital, were studied. The age-matched control group consisted of 167 healthy adults. Incorporation of [14C]-dT was measured on Day 1 in unstimulated monocyte-depleted lymphocyte cultures, and on Day 3 in cultures activated by PWM, ConA and PPD, T and B cells were enumerated by surface markers.

Prognistic relevance of radiation induced immune suppression in breast carcinoma.

The extent of radiation induced immune suppression was analysed in 100 patients with carcinoma of the breast. The relative changes of lymphocyte counts and stimulations by PHA and PPD were similar in patients who differed with regard to age, size of tumour and its malignancy grade or axillary node condition. Moreover, no difference in the degree of radiation induced immune suppression existed between patients who developed recurrent disease and those who remained free of disease during a follow-up period of 4 1/2 to 7 years.

Prognostic relevance of immunologic variables in breast carcinoma.

A series of 203 consecutive patients with operable carcinoma of the breast was analysed with regard to correlations between a set of immunologic and clinical variables existing at the time of the diagnosis. No major correlations were revealed between immunologic variables on the one hand and clinical features or the course of the disease on the other. The well-known prognostic relevance of tumour size, involvement of the axilla and the histological grade of malignancy was evident.
