Clinical aspects of antiaging
Ikuo Taniguchi. MD. PhDDirector, IMSJ
As the theme of the beginning of 2013, I had chosen aging which is a thing that we cannot avoid while we are alive. In

Japan, the increase in the number of elderly has become a major social issue. Anti-aging can be said as an ultimate preventive medicine as it is a wish to live healthily as one’s corresponding age rather than restoration of youth. Aging of brain and aging of the internal organs are hard to evaluate objectively, but aging of appearance varies greatly from person to person such as people who look younger or people who look older. Today I would like to introduce you the lectures on anti-aging of skin and bone which have a great influence on the appearance of aging from a medical point of view. Let's welcome Professor Shigeru Nakagawa from the Dermatology Department of Jikei University, School of Medicine on the topic of "Aging of skin and the prevention of it" and Professor Mitsuru Saito from

【Lecture I】
Poor bone quality in life-related disease: a possible explanation for
bone fragility in aging, osteoporosis, and diabetes mellitus
Mitsuru Saito, MD, PhDAssociate Professor, Department of Orthopedic Surgery,
The Jikei University School of Medicine Collagen cross-linking, a major post-translational modification
of collagen, plays important roles in the biological and biomechanical features of bone. Collagen cross-links can be divided into lysyl hydroxylase and lysyl oxidase-mediated enzymatic immature divalent cross-links, mature trivalent pyridinoline and pyrrole cross-links, and glycation- or oxidation-induced non-enzymatic cross-links(Advanced glycation end products: AGEs)such as glucosepane and pentosidine. These types of cross-links differ in the mechanism of formation and in function. Material properties of newly synthesized collagen matrix may differ in tissue maturity and senescence from
older matrix in terms of cross-link formation. Additionally, newly synthesized matrix in osteoporotic patients or diabetic patients may not necessarily be as well-made as age-matched healthy subjects. Data have accumulated that collagen cross-link formation affects not only the mineralization process, but also microdamage formation. Consequently, collagen cross-linking is thought to affect the mechanical properties of bone. Furthermore, recent basic and clinical investigations of collagen cross-links seem to face a new era. For instance, serum or urine pentosidine levels are now being used to estimate future fracture risk in osteoporosis and diabetes. In this review, we describe age-related changes in collagen cross-links in bone and abnormalities of cross-links in osteoporosis and diabetes that have been reported in the literature.

Skin aging and preventive strategies

also influenced by exogeneous factors, in particular, ultraviolet irradiation resulting in premature skin aging referred to as photoaging. Intrinsic skin aging is strongly influenced by hormonal changes of sex hormones. Especially, the deficiency in estrogens and androgens cause dryness, epidermal atrophy, wrinkling due to collagen breakdown and loss of elasticity. Ultraviolet irradiation is absorbed in chromophores and the energy is conversed to chemical reactions, resulting in skin aging and photocarcinogenesis. The formation of reactive oxygen species and the induction as well as activation of matrix metalloproteinases play the central role in skin aging. Skin aging can be considered as the accumulation of different deleterious changes in tissues and cells, leading to the progressive impairment of biological functions and the increase of the risk of development of skin diseases including skin cancers. Therefore, to investigate the precise mechanisms of exogeneous factors in skin aging will further contribute to the development of various therapeutic and preventive strategies for skin aging.
Introduction of the speaker of discourse
Ikuo Taniguchi. MD, PhD Director, IMSJ
Shiseido is a top brand in the cosmetics industry. In recent years, it can be seen that the management of the company had put a great effort on the expansion of the global development and development of the human resources. This innovative management reformation is introduced by the Chairman Shinzo Maeda. Mr. Maeda joined Shiseido after graduating from Keio University in 1970. He had been involved in the corporate planning on the cosmetics business and international business. In 2005, he had become the president of Shiseido. And in 2011, he was promoted to Chairman. Today he will talk about the CSR(corporate social responsibility)of Shiseido.
Towards the improvement of corporate value
Shinzo Maeda Chairman Representative Director SHISEIDO Co., Ltd.
Recently, CSR activities have a significant impact to corporate and I will introduce some examples of our company on CSR.
In recent years, "environment" is one of the most important issues in the world, and our company agrees with "Initiative on Climate Change" proposed by the Global Compact Network of United Nations.

In 2009, Shiseido had become the first company certified as "Eco-First" in the cosmetics industry, which aims at symbiosis of corporate activities and environmental activities. Especially Eco-First, in order to carry out unique activities of Shiseido such as "a new lifestyle proposal on symbiosis of ecology and beauty", we have declared "reduction of the emission of CO2", "effort towards the realization of a recycling society" and "proposal on achieving a society where people and society can live together in symbiosis beautifully".
The environmental activities of our company covered all areas of activity. For example, solar power generation equipment had been introduced in the factory in the United States and 70% of annual energy consumption are covered by sunlight. Also, wind power generation had been introduced in other factories. Both the factories in Japan and overseas are promoting zero emissions. On the aspects of the product, plastic of low environmental load which is made by "polylactic acid", a plastic of are used. "Polylactic acid" is made by regeneration and plant-based plastic resins. Also, containers are produced from polyethylene extracted from sugarcane. A lot of efforts had been done in it. In the logistic aspect, delivery
cardboard is made in decahedron shape which results in reducing the use of paper itself and the increase in volume ratio. It is also effective in reducing CO2.
The environmental activities introduced now are positioned as "Basic CSR activities". "Shiseido Earth Care Project", an environment project which is planned by all employees is also started.
On the other hand, Societies which is related to dermatology such as Japanese Dermatological Association, Japanese Society for Burn Injuries and Japanese Society of Pressure Ulcers, Societies which is related to pharmacy such as Japanese Nursing Association, and Japanese Cancer Society are collaborated together to cover the problem of hair loss of eyebrows and eyelashes, dullness of skin and color change of the tip of toes by makeup techniques. Also, tailored-made counseling is done for individuals and activities to support the improvement of the QOL are carried out. These activities are "Shiseido’s unique contribution to society" which is carried out through makeup which is our core business. Furthermore, we visit elderly home and disabled facilities to carry out beauty workshops in Japan and also overseas.
