[Activating help--aims and limits (author's transl)].

The publication attempts to analyze current work directed at aiding and encouraging aged people in the Federal Republic of Germany, seen from the viewpoint of the various welfare associations, and hense from a practical angle. The considerable contrast between aims, available knowledge, and realization, is made clear by discussing individual problem fields while presenting a catalog of relevant and necessary measures. The paper also describes the requirements training and continuing education, as well as the need for research based on practice and yielding results which are relevant in the everyday life of the aged.

Antigen presentation at the inflammatory site.

The introduction of antigen into tissues can induce an inflammatory response initiated by antigen-specific T lymphocytes. Central to this process is the recognition of antigen by specific T cells that cannot respond to intact antigen directly, but rather recognize antigenic fragments in association with gene products of the major histocompatibility complex (MHC) displayed by an antigen-presenting cell. To present antigen effectively, a cell must internalize antigen, process it to the immunogenic moiety, present the antigen in the context of a MHC molecule, and deliver various antigen-nonspecific signals required for T-cell activation. At the initiation of an immune response, the cells with the capacity to perform all of these functions are limited to a few specialized cell types, including monocytes/macrophages, dendritic cells, B cells, and Langerhans cells. Once the immune response has been initiated, however, cytokines and other factors, released by activated cells at the inflammatory site, stimulate a variety of changes in various cell types that alter their capacity to function as antigen-presenting cells and facilitate antigen-induced T-cell activation. Therefore, as the immunologically mediated inflammatory response evolves, a variety of changes occur within the local environment that enhance and/or modulate the capacity of T cells to recognize and respond to the inciting antigen. The purpose of this review is to catalog the changes in the function of antigen-presenting cells at inflammatory sites that might alter the nature of the immune response.

The switch library: new service in rehabilitation librarianship.

This article discusses the role of assistive devices in patient rehabilitation programs and the problems in evaluating and assessing patients for prescribing these devices. The rehabilitation library can solve many of these problems and enhance patient rehabilitation programs by providing a circulation service for adapted microswitches and other assistive devices. The article outlines library management of such a program, including funding, acquisitions, classification, and cataloging strategies. A comprehensive library classification scheme for assistive devices is proposed, and schedules are given for microswitches and environmental controls. It is predicted that this service will rapidly expand nationally over the next decade to become an integral part of rehabilitation library patient services.

In vitro magnetic resonance properties of CNS neoplasms and associated cysts.

Fresh surgical specimens of central nervous system (CNS) neoplasms were analyzed with particular attention to differences between the T1 and T2 values of the solid and cystic components. Delineation of solid tumor from cyst is important, particularly when surgical intervention is planned, since only the solid portion need be excised. Total protein concentration determinations and microimmunoelectrophoresis for protein distribution and characterization also were performed on the fluid specimens. To diagnose a lesion on magnetic resonance based on T1 and T2 measurements, one must first have a catalog of values on which to base that diagnosis. The authors are reporting such values at 0.25 T. In addition, protein analysis of the fluid specimens has shown that the cysts of the CNS associated with CNS neoplasms are, in fact, transudates rather than collections of cerebrospinal fluid (CSF). Their T1 should permit differentiation from solid portions of neoplasms and from non-neoplastic syringohydromyelia.

Report of a cooperative venture between the China Medical University library and the medical library of McGill University.

In March/April 1986, the medical library at McGill University in Montreal, Canada signed a cooperative agreement with the China Medical University (CMU) Library in Shenyang, China. This paper analyzes the operations of the CMU library within the context of the Chinese system of medical education, health care delivery, and medical librarianship. The CMU library is described in terms of collections, cataloging procedures, filing, public services (reference, bibliographic instruction, circulation, copy service), interlibrary loans, networking, conservation of materials, and personnel. Some interesting comparisons are made between the two libraries with respect to holdings, services provided, and training of staff. The plans for future cooperation are outlined.

An atlas of a rare neuronal surface antigen in the rat central nervous system.

The mature nervous system contains functional synaptic networks composed of neuronal sets and subsets whose identity and maintenance may rely on external surface molecules specific for these neuronal subdivisions. Such molecules may reside permanently on specific neurons, serving to identify those neurons within a complex population. From a collection of monoclonal antibodies made to the Torpedo cholinergic synaptosome preparation, we have identified several antibodies that bind the surface of some, but not all, neurons of the mature rat brain (Kushner and Stephenson, 1983; Kushner, 1984). In the present study we catalog which neurons of the entire rat brain and spinal cord are immunopositive for one of these antibodies, Tor 23. The atlas we have compiled can be used (1) on a practical level to guide affinity purifications and neuronal cell sorting, and (2) more esoterically to address whether surface antigenic sets of neurons share or define a common functional property. In the forebrain, Tor 23-positive neurons predominate as a rare cell type of the inner cortical laminae. In the midbrain, few cells stain. In the hindbrain, labeled neurons are dispersed among several nuclei. The exceptions to these observations, areas that almost exclusively contain Tor 23-immunopositive neurons, are the spinal cord ventral horn, the deep cerebellar nuclei, some cerebellar-related nuclei, selected auditory nuclei, the supraoptic and paraventricular nuclei of the hypothalamus, and the CA2 pyramidal neurons of the hippocampus. The neurons that bind Tor 23 are related biochemically by virtue of that shared epitope alone. Whether they are related in a functional manner is a separate issue. Tor 23 demarks many motor-related structures, specifically, the ventral horn motor lamina, the orofacial motor nuclei 5 and 7, the ambiguus nucleus, the deep cerebellar nuclei, the pontine reticulotegmental nucleus, the lateral reticular nucleus, the gigantocellular reticular nucleus, the red nucleus, and neurons within the motor and somatosensory cortices. The overlap of Tor 23 with motor structures suggests that Tor 23 is a motor system marker.

Detective magazines: pornography for the sexual sadist?

The origins of detective magazines can be traced to 17th and 18th century crime pamphlets and to 19th century periodicals that Lombroso called "really criminal newspapers." Content analysis of current detective magazines shows that their covers juxtapose erotic images with images of violence, bondage, and domination; that their articles provide lurid descriptions of murder, rape, and torture; and that they publish advertisements for weapons, burglary and car theft tools, false identification, and sexual aids. Six case histories of sexual sadists illustrate the use of these magazines as a source of fantasy material. We postulate that detective magazines may contribute to the development of sexual sadism, facilitate sadistic fantasies, and serve as training manuals and equipment catalogs for criminals. We recommend that detective magazines be considered during policy debates about media violence and pornography.

Heterogeneity in the membrane proteins of human lymphoid cell lines as seen in sodium dodecyl sulfate-polyacrylamide electrophoresis slab gels.

The proteins of [35S]methionine-labeled membranes of six human lymphoid cell lines were examined by electrophoresis in sodium dodecyl sulfate-polyacrylamide gradient slab gels in order to identify molecular differences among these tumors. The lymphoid cells were internally labeled with [35S]methionine, their membranes were isolated, and the reduced and alkylated membrane proteins were treated electrophoretically in sodium dodecyl sulfate-polyacrylamide gradient slab gels. The gel patterns of over 100 membrane proteins per cell were highly complex but reproducible and, in that sense, constituted fingerprints of the individual tumors. Several proteins occurred uniquely on one or a few tumors. Some protein bands were identified to be serologically recognized membrane antigens by electrophoresis of immunopurified antigen in parallel to membrane samples. p44,12, a complex of proteins with molecular weights of 44,000 and 12,000 (HLA-A and -B antigens and beta2-microglobulin), and p29,34, (HLA-D antigen) were identified in this manner. High-resolution sodium dodecyl sulfate-polyacrylamide gradient gel electrophoresis can be used to catalog and describe lymphocyte membrane proteins and perhaps to identify subsets of lymphoid cancers.

EARS: Electronic Access to Reference Service.

Electronic Access to Reference Service (EARS) is a front end to the Health Sciences Library's electronic mail system, with links to the online public catalog. EARS, which became operational in September 1984, is accessed by users at remote sites with either a terminal or microcomputer. It is menu-driven, allowing users to request: a computerized literature search, reference information, a photocopy of a journal article, or a book. This paper traces the history of EARS and discusses its use, its impact on library staff and services, and factors that influence the diffusion of new technology.

Medical libraries and computers. The role of medical libraries in medical informatics.

The classic function of health sciences libraries is to build and maintain a knowledge base and to provide timely access to that collective memory for the purpose of learning, teaching, caring for patients, conducting research or managing an organization. The formats and representation of that knowledge base are changing rapidly, as are the methods and techniques for gaining access to information. Medical libraries have long used computers for cataloging and controlling records but are now shifting to acquiring, managing and distributing bibliographic and full-text information to local library "networks."

Health care machine-readable data files: secondary analysis, access, and the role of the library.

Access to health care machine-readable data files (MRDF) is becoming increasingly important to students and researchers in the health care field who use the data in secondary analysis. Health sciences libraries must play a role in providing such access, and this role should consist primarily in providing users with information about the identity and contents of available MRDF and about how they may be obtained. Libraries should therefore collect extensive materials containing information about the MRDF that may be of interest to their users. Many such materials are available in print, and their quality may be expected to improve as newly developed methods and procedures for constructing bibliographic citations, abstracts, and catalog entries for MRDF are put into practice. Also, it is now feasible to incorporate data file abstracts into existing online bibliographic databases.

Library orientation methods: J. Hillis Miller Health Center Library program.

Two orientation devices are described which are currently in use at the J. Hillis Miller Health Center Library. One is a taped tour which requires a portable recorder with earphones attached. Tapes are now available for nursing students, physical therapy students, and Health Center staff. The tour includes location information and description of the card catalog and certain basic index and abstract services. The second orientation device is a short instruction tape on the use of Index Medicus which is attached to the Index Medicus table. This is heard through a telephone apparatus. It is anticipated that the tape technique will be expanded to apply to other students and other library tools. It is also believed that this technique may be used in other libraries. Information about the supplies and equipment used is given as an addendum.

Hospital-based patient education programs and the role of the hospital librarian.

This paper examines current advances in hospital-based patient education, and delineates the role of the hospital librarian in these programs. Recently, programs of planned patient education have been recognized by health care personnel and the public as being an integral part of health care delivery. Various key elements, including legislative action, the advent of audiovisual technology, and rising health care costs have contributed to the development of patient education programs in hospitals. As responsible members of the hospital organization, hospital librarians should contribute their expertise to patient education programs. They are uniquely trained with skills in providing information on other health education programs; in assembling, cataloging, and managing collections of patient education materials; and in providing documentation of their use. In order to demonstrate the full range of their skills and to contribute to patient care, education, and research, hospital librarians should actively participate in programs of planned patient education.

The health sciences library's contributions to patient care.

The medical librarian in a hospital contributes to the quality of patient care by building a library which can provide promptly the information needed by all members of the treatment team, including medical and paramedical persons. The librarian is meeting his responsibility to the patient when he performs the duties of selecting materials, cataloging these materials speedily and thoroughly, and giving reference service to library users. An excellent hospital library and the services of a knowledgeable librarian can be a significant factor in the medical team's ability to provide superior patient care.

A film program in a teaching hospital.

The Martland Hospital Medical Library has for more than a year been conducting a 16mm film program for interns, residents, attending physicians, and nurses as an adjunct to continuing education. It was possible to run this project on a minimal budget because many films are available at little or no cost from governmental agencies, pharmaceutical companies, medical associations, and universities. The program is run on a departmental basis. Films for a department are selected by the chief resident in that department from a list which the librarian has prepared of available films in the specialty involved. The library orders and publicizes the films and transacts all business in connection with them. Films pertinent to clinical practice are preferred. The administration of this program is described in this paper, and a number of film catalogs are evaluated. Criteria for film selection are discussed.
