Developmental Vitamin D Deficiency Alters Mk-801-Induced Behaviours In Adult Offspring, James Kesby, Jonathan O'Loan, Suzanne Alexander, Chao Deng, Xu-Feng Huang, John Mcgrath, Darryl Eyles, Thomas Burne

Xu-Feng Huang

Rationale Developmental vitamin D (DVD) deficiency is a candidate risk factor for developing schizophrenia in humans. In rodents DVD deficiency induces subtle changes in the way the brain develops. This early developmental insult leads to select behavioural changes in the adult, such as an enhanced response to amphetamine-induced locomotion in female DVD-deficient rats but not in male DVDdeficient rats and an enhanced locomotor response to the Nmethyl- D-aspartate (NMDA) receptor antagonist, MK-801, in male DVD-deficient rats. However, the response to MK- 801-induced locomotion in female DVD-deficient rats is unknown. Therefore, the aim of the current study was to further examine …

Perinatal Administration Of Pcp Alters Adult Behaviour In Female Sprague-Dawley Rats, Teresa Du Bois, Xu-Feng Huang, Chao Deng

Xu-Feng Huang

Perinatal phencyclidine (PCP) treatment leads to neuronal damage and causes long-term behavioural alterations in rodents. This study examined the effects of perinatal PCP treatment on behaviour of adult rats in holeboard, elevated plus maze, social interaction and forced swim tests. PCP-treated rats displayed hyperactivity in the holeboard and forced swim tests. These persistent behavioural changes are relevant to the study of psychiatric disorders such as schizophrenia.

The Responsiveness Of State Mental Health Authorities To Parents With Mental Illness, Kathleen Biebel, Joanne Nicholson, Valerie Williams, Beth Hinden

Joanne Nicholson

The majority of adults with serious mental illness living in the community are parents, many of whom may be receiving services from State Mental Health Authorities (SMHA). Innovative intervention approaches are available to improve outcomes for these parents and their children. Analyses of SMHA and state-level data, as well as qualitative interviews of administrators, service providers, and consumers, underscore the importance of organizational structure and philosophy, an advocacy presence, and available funding to SMHA efforts on behalf of parents and their families.

Mothers With Mental Illness: I. The Competing Demands Of Parenting And Living With Mental Illness, Joanne Nicholson, Elaine Sweeney, Jeffrey Geller

Joanne Nicholson

OBJECTIVE: The purpose of this study is to understand the parenting experiences of women with mental illness from the perspectives of mothers and case managers employed by the state department of mental health. METHODS: Six focus groups of mothers and five focus groups of case managers met to discuss the problems facing mothers with mental illness and to recommend solutions. Focus-group transcripts were coded and items grouped by themes in qualitative analyses to explore the conflicts mothers face in meeting the dual challenges of parenting and living with mental illness. RESULTS: Mothers and case managers identified sources of conflict in …

Mothers With Mental Illness: Ii. Family Relationships And The Context Of Parenting, Joanne Nicholson, Elaine Sweeney, Jeffrey Geller

Joanne Nicholson

OBJECTIVE: This study explores the experiences of mothers with mental illness regarding their family relationships.

METHODS: Six focus groups of mothers with mental illness and five focus groups of case managers met to discuss problems facing mothers with mental illness and to recommend solutions. Focus groups were audiotaped, and transcripts were coded and analyzed qualitatively to describe ways in which husbands and partners, grandparents, and other family members contribute to the context of parenting for mothers with mental illness.

RESULTS: Mothers with mental illness and case managers described a range of relationships and attitudes of family members and provided examples …

Temporal Trends And Factors Associated With Extent Of Delay To Hospital Arrival In Patients With Acute Myocardial Infarction: The Worcester Heart Attack Study, Jorge Yarzebski, Robert Goldberg, Joel Gore, Joseph Alpert

Jorge L. Yarzebski

Factors associated with delay to hospital arrival after the onset of symptoms suggestive of acute myocardial infarction (AMI) were examined in the late 1960s and 1970s, but recent data concerning these characteristics are limited. The purpose of the present study was to examine overall and temporal distributions of the extent of patients' delay from the time of onset of AMI symptoms to hospital arrival and factors associated with delay in seeking medical care from a multihospital, population-based perspective. Review of medical records was undertaken of patients hospitalized with a discharge diagnosis of AMI in 16 teaching and community hospitals in …

Patient Delay And Receipt Of Thrombolytic Therapy Among Patients With Acute Myocardial Infarction From A Community-Wide Perspective, Robert Goldberg, Jerry Gurwitz, Jorge Yarzebski, J. Landon, Joel Gore, Joseph Alpert, P. Dalen, James Dalen

Jorge L. Yarzebski

The duration of patient delay from the time of onset of symptoms of acute myocardial infarction (AMI) to hospital presentation, and the relation of delay time and various patient characteristics to receipt of thrombolytic therapy were examined as part of a community-based study of patients hospitalized with AMI in the Worcester, Massachusetts, metropolitan area. In all, 800 patients with validated AMI hospitalized at 16 hospitals in the Worcester metropolitan area in 1986 and 1988 constituted the study sample. Patients delayed on average 4 hours between noting symptoms suggestive of AMI and presenting to area-wide emergency departments with no significant change …

Polymorphonuclear Functions In Patients With Mixed Connective Tissue Disease, E. Bodolay, Katalin Lukacs, G. Frendl, Gyongyi Szabo, G. Arato, Gyula Szegedi

Gyongyi Szabo

Polymorphonuclear leukocytes (PMNs) from 29 patients with mixed connective tissue disease (MCTD) were studied "in vitro" for their phagocytic and chemotactic function as well as for granulocyte alkaline phosphatase (GAP) activity. Fc-receptor expression detected by EA-rosette formation was comparable to the control. Yeast-phagocytosis, C3b-receptor mediated phagocytosis and chemotaxis of PMNs, however, significantly decreased in MCTD. At the same time, photometric measure of alkaline phosphatase activity indicated a nearly two fold increase in PMNs from patients with MCTD. Although no correlation was found between PMN functions and the activity of the disease, PMN disorders may play a role in pathogenesis of …

Monocyte Functions In Patients With Mixed Connective Tissue Disease, E. Bodolay, Katalin Lukacs, Gyongyi Szabo, G. Frendl, T. Ben, Gyula Szegedi

Gyongyi Szabo

The authors investigated the number and functions of peripheral blood monocytes in patients with mixed connective tissue disease. Moderate monocytopenia was detected in the active stage of the disease. There was a close correlation between the sensitized sheep red blood cell binding capacity of monocytes and the elevated levels of circulating immune complexes. The yeast phagocytosis of monocytes and the chemotactic activity were normal in patients with mixed connective tissue disease. C3b receptor mediated phagocytosis of monocytes decreased in the active and inactive stages of the disease. This study suggests that the decreased function of C3b receptors of monocytes is …

Selective Induction Of Mononuclear Phagocytes To Produce Neopterin By Interferons, Gabriele Bitterlich, Gyongyi Szabo, Ernst Werner, C. Larcher, Dietmar Fuchs, Arno Hausen, Gilbert Reibnegger, T.F. Schulz, J. Troppmair, Helmut Wachter

Gyongyi Szabo

Interferon-gamma (IFN-gamma) has been shown to be a potent inducer of neopterin secretion by human peripheral blood monocytes/macrophages (1). In this paper, it is shown that other known stimuli of monocytes (e.g., to secrete proteases or to migrate) such as zymosan-activated human serum, lipopolysaccharide, human C3/iC3 and zymosan coated with complement were unable to trigger monocytes/macrophages to release neopterin. Monocytes/macrophages could be stimulated solely by IFN-gamma (25 U/ml) and IFN-alpha at very high concentrations (10,000 U/ml). In the case of human peripheral blood mononuclear cells (PBMNC), basically the same pattern was observed. If however, in the buffer controls PBMNC showed …
