Estrogen provides beneficial effects on hyperlipidemia in climacteric and elderly women. In this study of 68 women (37 to 67 years old), hepatic triglyceride lipase (HTGL), lipoprotein lipase (LpL) serum lipids and apolipoproteins were analyzed to investigate the effects of estrogen replacement therapy (ERT). After menopause, LpL, total cholesterol, low-density lipoprotein (LDL)-cholesterol, and apolipoprotein B increased. But ERT suppressed total cholesterol, LDL-cholesterol, apolipoprotein B, and especially apolipoprotein E in menopausal women. The mechanism was thought that ERT significantly suppressed HTGL, but LpL was not affected. Estrogen also increases hepatic LDL receptors and accelerates transfer of serum LDL-C (and TC). It was said that HTGL accelerates conversion of intermediate-density lipoprotein (IDL) to LDL. The suppression of HTGL by the ERT may decrease conversion of IDL to LDL and lower LDL-C (and TC). These estrogen's beneficial effects on lipids, may prevent the atherosclerosis. In addition, apolipoprotein E increases senile plaques in senile dementia-Alzheimer's type. The decrease in apolipoprotein E with ERT may be related to cognitive functions of elderly women.

Werner's syndrome (WS), a representative progeroid syndrome with chromosomal instability caused by the mutation of RecQ type DNA/RNA helicase, manifests skin changes similar to those observed in systemic sclerosis (SSc). In addition, patients with WS show a variety of the signs and symptoms of normal ageing at an early stage of their life; gray hair, alopecia, muscle atrophy, osteoporosis, cataracts, hypogonadism, diabetes mellitus, hyperlipidemia, atherosclerosis, malignancy, brain atrophy, and senile dementia. Although no direct evidence has been presented linking RecQ type DNA/RNA helicase dysfunction with the occurrence of premature ageing symptoms in WS, WS may give us a unique model to analyze the skin changes and the mechanisms of fibrosis in SSc.

The "lifestyle-related disease" has been increasing in Japan as the population advances in age and the food culture becomes westernized. Although prevention, treatment and therapy for this disease have been attempted using certain kinds of food and nutritive elements, so-called "health foods" such as DHA and EPA, which are mostly contained in fish oil, have been a special focus within these attempts. There have been many reports regarding the pharmacological functions and the mechanisms of DHA and EPA. Also, in the past few years, it has become possible to produce ingestible DHA and EPA oils, oils for chemical compounds, oils for animal feed, and highly purified DHA and EPA for medical and pharmaceutical use. EPA ethyl ester has a wide market as a preventive medicine in Japan. Initially in 1990, this medicine was administered in cases of arterisclerosis obliterans, using its anti-platelet aggregation ability. Four years later, in 1994, its effectiveness in triglyceride reduction was recognized, and its application was extended to cases of hyperlipidemia, which has remarkably broadened its market. Clinical studies with DHA have shown improvement in senile dementia (cerebral thrombosis, Alzheimer's disease), atopic dermatitis, and the ability to focus on moving objects, as well as control of aggressiveness against others caused by stress, and prevention of hyperlipidemia, hypertension, and cancer.
