In order to clarify whether children's food intakes made their bone weak and caused their fractures, the food intakes of 70 children aged 8-14, who suffered fractures over three times, were surveyed for three days. And nutritional analysis of their food intakes and food pattern analysis of them were done in comparison with those of the children suffered non of fractures.
The results were as follows.
1)　Nutrient intakes of the fractured children were more sufficient than those of the control.
2)　But on calcium intake, there was not a difference between them and calcium/phosphorus ratio of the fractured children was significantly lower than that of the control.
3)　In comparison with the control, the fractured children took more meat and drink and less cereals, milk and seaweed.
4)　By multiple regression analysis, it was found that lower calcium/phosphorus ratio of the fractured children was caused by their less intakes of seaweed and milk and more intakes of meet.
5)　Principal component analysis proved that the fractured children had more tendency of selecting their foodstuffs by their preference for them than the control.
The results suggested that the children suffered frequent fractures had a pattern of food intakes which lowered the calcium utilization and influenced on the occurrences of their fractures.

To evaluate a desirable method for scalp disinfection, we studied recovery course and number days with 110 serial dressing changes after brain surgery.
We obtained the following results;
1.　The disinfection by Isodine solution alone filled 4 of 5 requirements in scalp disinfection except crusting.
2.　Combination of Isodine-hypoalcohol was not appropriate to the disinfection, because this combination disturbed epithelization.
3.　Disinfection with combination of Iodine tincturehypoalcohol was sometimes found incomplete, because it needed 5 minutes before effects were obtained.
4.　Since the combination of hypoalcohol-Isodine showed antiseptic effects and induced less crusting, it is, therefore, thought that this combination is second choice next to Isodine solution alone.

The maternal obesity was studied in mice.
Changes in body weight, fat weight/body weight, daily food intake, liver glycogen, blood glucose, blood proteins and tyrosine aminotransferase activity were examined during pregnancy, lactation and weaning (recovery) periods.
The results were as follows;
1)　The maternal obesity was observed after weaning in lactated mice and after pregnancy in nonlactated mice. The extent of obesity was higher in lactated mice than in nonlactated mice.
2)　The increase of daily food intake was not observed at appearance of the obesity.
3)　The activity of tysosine aminotransferase, that is, the level of blood glucocorticoid, increased during pregnancy and lactation was decreased immediately after weaning. Then followed decreased of liver glycogen and blood glucose, and an increase of blood proteins.
