The effect of exercise on the elevation of HSP70 was studied in rats fed a different diet on the B_6 content (as pyridoxine 1.5 mg/kg diet or 7.5 mg/kg diet). Minimum requirement of B_6 in the diet is known to be about 1.5 mg/kg diet in 20 % casein diet. Rats were divided into 4 groups in each series and assigned as Sc (sedentary control), Se (sedentary-exhaustion), Ec (training control), and Ee (trainingexhaustion). HSP70 was determined in the heart, liver and gastrocnemius muscle (red and white portions). HSP70 in the heart was not changed in all groups of both series. In the liver HSP70 was elevated to very high levels in Sc and Ee groups in the rats fed the high level of B_6, and where as a little in Ee group in rats fed low level of B_6. The levels of inductions were in the muscle not so high very similar but as observed in the liver. AST (aspartate aminotransferase) activity was significantly elevated in Ec and Ee for the liver, and in the three groups for the kidney and muscle (red portion) in the rats fed the high level of B_6. On the contrary in all tissues in all groups fed low level of B_6, AST activity was not changed at all. Thus the low induction of HSP70 in the tissues, especially in the liver of rats fed the low B_6 diet, may suggest impairment of amino acid metabolism and, consequently, insufficiency of energy supply.

The recommended dietary allowance (RDA) of vitamin B_6 (B_6) for Japanese was formulated for the first time in the 6^<th> revised National Reference Intake in Japan. The RDA of infant is O.1mg/day in the 6^<th>revision. Milk intake of infant was calculated to be 850 ml/day in the 5^<th> revised RDA, however it was set at 750 ml/day based on investigation in the 6^<th> revised RDA. The B_6 intake of infant deeply depended on the content of B_6 in breast milk. Thus we determined the B_6 contents in breast milk of Japanese women. Milk samples were collected from 25 healthy nursing women whose infants were 2 - 5 ages in month. Total B_6 content in milk was quantified by HPLC. The average content of B_6 was 0.25 mg/l breast milk. This value was not different from those of other studies and the datum in 6^<th> revised RDA.
