    The kidney plays important roles in the maintenance of sodium balance. Regulation of glomerular filtration rate (GFR) and subsequent renal tubular reabsorption of sodium are essential. Various hormones and autacoids regulate renal hemodynamics and tubular reabsortion. The autoregulation of the kidney also plays a critical role. The responses of the kidney to salt depletion are more effective than those to salt overloading. Although the kidney participates in major way in the pathogenesis of hypertension, it is a matter of considerable dispute whether excessive dietary salt intake causes hypertension. Salt restriction is effective only in salt-sensitive subjects. Strict salt restriction might be of hazard to health. The policy of universal salt restriction should be avoided. It is expected to find simple method to identify the saltsensitivity.

    Bittern is a concentrate of seawater condensed by one thirtieth to one fortieth by volume. It contains, therefore, most of the minerals dissolved in seawater. But constituents and their contents are a little changed by depending on producing methods. What kinds of constituents in bittern are useful for human body as a supplement of minerals? Only major minerals such as magnesium, calcium and potassium are useful as nutrients of minerals. Many other minor minerals are not enough included to be useful for human body. Common bittern has little calcium, but the bittern made by ionexchange membrane electrodialysis method has calcium and more potassium than common bittern. So the former is superior to the later as supplement of minerals. One milliliter of the former bittern can supplement twenty and ten percent of magnesium and potassium intake needed in a day, respectively. Toshio, HASHIMOTO

    Deep ocean water (DOW), existing below ca 200m from the surface in the ocean, has been characterized with cleanliness and containing a number of minerals, which can be used for various purposes. One of the most significant effects of minerals in seawater is acceleration and completeness of fermentation processes for foods, alcohol and many others. Tastes of foods and drinks can also be improved by adding seawater and/or its salts. A stimulation of the growth of human skin cells and formation of cornified envelope during skin cell maturation opened DOW applications into skin care and subsidiary uses for medical skin treatments. Seawater is also applied for soil improvement by adding minerals and for improving tastes of vegetables, crop and fruits by spraying onto leaves. Although many of these effects can be made by surface seawater, DOW has a great advantage for foods, drinks and skin cares because these require high cleanliness.

    海洋細菌のMarinobacterium sp. DMS-S1は, 光の存在下でのみ硫化メチル (DMS) を硫黄源として生育できる海洋細菌である. この細菌の増殖の際に菌体外に放出されるフラビン類を定量したところ, 硫酸塩が充分にあればFAD, FMN, リボフラビンの順で多く, それぞれ100nmol/L, 10nmol/L, 1nmol/Lのオーダーであった. リボフラビン類, メチレンブルーとクロロフィルaを光増感物質としてDMSの光分解を検討したところ, リボフラビン類の場合はジメチルスルポキシド (DMSO) 以外にメタンスルホン酸が数十パーセント, 硫酸イオンが数パーセント生成したが, メチレンブルーとクロロフィルaでは生成物のほとんどはDMSOであり, リボフラビン類によるDMSの光分解にはメチレンブルーやクロロフィルaとは異なる機構が存在することが示唆された.
