“…More recent work in the writer's laboratory (9) has shown an apparent association of infection with lack of the vitamin G fraction. Matsumura and co-workers (10), moreover, have recently concluded that beriberi is an infectious disease in which a dietary deficiency is merely a predisposing factor. The correct evaluation of these findings must await the accumulation of further data.…”

The nutrition of an animal is reflected in its physical condition. Hence, to ascertain the nutrition problems in a given region it is necessary to know something of the physical condition of the people and their domestic animals.Among the questions that arise in the evaluation of this condition are: What specific deficiency syndromes are peculiar to the region? How prevalent is general malnutrition? Are there indications of a lack of resistance to infections? Are there marked abnormalities of bones or teeth? Is there normal reproduction and rearing of young and do the young grow to the full extent of their hereditary capacity? Then logically follows the query, what factors of climate, soil, dietary habits, or parasitic enemies have either a direct or an indirect relation to the conditions found? These questions should form the basis of our research programs.The writer is aware of only one nutritional disease that may be considered as peculiar to the South; this is pellagra. There were approximately 7400 deaths in the United States in 1928 which were registered as due to pellagra. Only 227 of these were outside the strictly southern states with 53 of this number in California and 12 in Arizona (1). Convincing evidence has not yet been presented that the diet of any class of people in the South is significantly poorer than that of people representing a comparable economic level in any other section of the country. The determination of the basic factors underlying this regional distribution of pellagra are an unanswered challenge.The available data show that the prevalence of other conditions that may be attributed in part at least to nutritional causes indicate that many dietaries of the South are far from optimum. They do not in general indicate any worse conditions, however, than are found throughout the nation.Studies made in Mississippi (2) show that 30-35 per cent of the groups of rural children examined were underweight, 45-50 per cent had decayed teeth, 57-67 per cent had infected tonsils, and 12-27 per cent showed marked evidence of rickets.Studies in Virginia (3) of 462 white school children show that 85 per cent had defective teeth; the same study shows only 60 per cent with decayed teeth in a group of 323 negro school children. A study of over 5000 negro school children in Atlanta, Georgia (4), shows45 per cent in a good state of nutrition as ,judged by clinical evidence; 35 per cent were in a fair state; 2336

“…In the early 1900s, individual food components began to be found. For example, vitamin B1 (oryzanin) was found in trials to overcome the deficiencies of military patients [ 2 ]. Vitamin E was isolated from wheat germ oil, which was found to be involved in rat reproduction [ 3 ].…”

Iron is the most abundant mineral in the human body and plays essential roles in sustaining life, such as the transport of oxygen to systemic organs. The Fenton reaction is the reaction between iron and hydrogen peroxide, generating hydroxyl radical, which is highly reactive and highly toxic to living cells. “Ferroptosis”, a programmed cell death in which the Fenton reaction is closely involved, has recently received much attention. Furthermore, various applications of the Fenton reaction have been reported in the medical and nutritional fields, such as cancer treatment or sterilization. Here, this review summarizes the recent growing interest in the usefulness of iron and its biological relevance through basic and practical information of the Fenton reaction and recent reports.

Case 2.-A man, aged 29 years, presented himself because of right facial paralysis and deafness in the right ear. Three months before he came to the clinic, he had been shot with a 0.22 caliber bullet, fired at a distance of 40 feet. The bullet entered his head at a point 1 inch in front of the right ear. He did not lose consciousness. The injury was immediately followed by right facial paralysis and profound deafness in the right ear. He had been operated on elsewhere shortly after Fig. 2.-Bullet in the right middle ear.the accident, in an effort to remove the bullet, but this operation had been unsuccessful.On examination of the right ear when he came to the clinic, landmarks were obliterated, and a note was made that there was something hard behind the drum, or something crowding the drum from above. A roentgenogram gave evidence that the bullet was in the middle ear. The mere presence of the
