Primary Sjögren's syndrome is an autoimmune disorder characterized by lymphocytic infiltrates and destruction of the salivary and lacrimal glands, and systemic production of autoantibodies to the ribonucleoprotein (RNP) particles SS-A/Ro and SS-B/La, leading to clinical symptoms of dryness of the mouth and eyes (sicca syndrome). Autoreactive T cells bearing the CD4 molecule may recognize an unknown self antigen, triggering autoimmunity in the salivary and lacrimal glands. Although several candidate autoantigens including α-fodrin have been reported in Sjögren's syndrome, the pathogenic roles of the autoantigens in initiation and progression of SS are still unclear. It is possible that individual T cells activated by an appropriate self antigen can proliferate and form a restricted clone. Recent evidence suggests that the apoptotic pathway plays a central role in making T cells tolerant to tissue-specific self antigen, and may drive the autoimmune phenomenon. We recently reported that tissue-specific apoptosis in estrogen-deficient mice may contribute to autoantigen cleavage, leading to the development of autoimmune exocrinopathy. The studies reviewed imply that tissue-specific apoptosis and caspase-mediated α-fodrin proteolysis are involved in the progression of autoimmune lesions in Sjögren's syndrome. Moreover, Fas ligand (FasL) and its receptor Fas are essential in the homeostasis of the peripheral immune system. It is considered that a defect in activation-induced cell death (AICD) of effector T cells may result in the development of autoimmune exocrinopathy in Sjögren's syndrome.

OBJECTIVESTo evaluate the physical strength, cerebral function, and mental health conditions in elderly persons, and to examine the correlation between these functions.

METHODSThe subjects were 151 independent-living elderly Japanese women, mean age 70 +/-5 years (+/-SD; range, 60 to 80 years), with normal abilities in daily life. The health check-up was conducted from April to May 1997. Physical strength was estimated by measuring seven activities. Cerebral functions were assessed by six sub-tests of the General Aptitude Test Battery (GATB). Their mental health status was measured by four sub-scales of the General Health Questionnaire (GHQ)-28.

RESULTSThe physical strenght and almost all of the cerebral functions decreased with age. Social dysfunction and severe depression on the GHQ sub-scales also worsened with age. Physical strength was strongly correlated with cerebral functions after adjusting for the confounding effect of aging. There were also interrelations between physical strength and mental health.

CONCLUSIONSThis study provided important information on the correlation between physical and mental status in elderly women. Future longitudinal studies with the intervention of physical training are required to determine whether a causal relationship exists between these factors.

Objective: To examine how best to provide information on over-the-counter (OTC) drugs in the future, the Japan Self-Medication Industry (JSMI) conducted an online survey on public attitudes toward changes in the system for controlling the sales of OTC drugs specified by the revised Pharmaceutical Affairs Act effective since June 2009.
Methods: A secure web-based questionnaire system was developed and linked to the JSMI website.  The survey was conducted between July 17 and August 31, 2009.
Results: Of the 4,257 people who responded to the questionnaire, 56.8% indicated they understood the provisions of the revised Pharmaceutical Affairs Act.  More than half of the responders had positive opinions of the revision.  They welcomed the improvement in convenience resulting from the availability of drugs at convenience stores, but “Druggists,” who are responsible for sales of the drugs, were not sufficiently represented among responders.  It was inferred that the general public feels that they should be able to purchase OTC drugs for self-medication after receiving sufficient information about the drugs from qualified sources.
