In the large compound kitchens of the gold mines of the Witwatersrand, where food is prepared for over a quarter of a million Bantu workers, there is a present trend to replace open cooking by pressure cooking. Of the food consumed, the vegetable stew is the chief, and sometimes the sole, source of vitamin C; however, since scurvy occurs infrequently, the amount of the vitamin provided up to no...

Man and primates have an inborn error in metabolism which renders them incapable of synthesizing ascorbic acid. Clemetson and Anderson reported premature deliveries to vitamin C deficient mothers(1). Vitamin C deficiency in the mother has also been associated with increased morbidity, mortality, still birth, premature and low birth weight(2). Paucity of studies on Indian women and neonates led ...

The experimental evidence presented in this paper shows that multiple paralytic doses of poliomyelitis virus, when mixed with very small amounts of crystalline vitamin C (ascorbic acid), are rendered non-infectious as determined by intracerebral injection of such mixtures into rhesus monkeys.

An error was made with the cutoff vitamin C level reported in this paper (>50 mmol/l). The units should have been given in micromoles per litre, not millimoles per litre, for vitamin C. Throughout the manuscript, wherever >50 mmol/l is given as the cutoff, >50 micromol/l is the correct vitamin C level that should have been reported.

Tuberculosis. At the beginning of the 19th century this disease caused one-fifth of all deaths in western Europe. In London the rate was even higher—30 per cent. In the large American cities the death rate at that time was about 400 per 100,000 of population. To illustrate the rate of decline in England the figures for the city of Ipswich in ten-year averages from 1840 to 1940 are as follows: 3...

The objective of this work was to determine the effects of blanching and two drying methods, open-sun drying and natural convection solar drying, on the quality characteristics of red pepper. A 2 × 3 factorial design with experimental factors as 2 drying methods (open-sun drying and use of solar dryer) and 3 levels of pepper blanching (unblanched, blanched in plain water, and blanched in 2% NaC...

Background: The neonatal brain is particularly vulnerable to imbalances in redox homeostasis because of rapid growth and immature antioxidant systems. Vitamin C has been shown to have a key function in the brain, and during states of deficiency it is able to retain higher concentrations of vitamin C than other organs. However, because neurons maintain one of the highest intracellular concentrat...

Since 1971, 21 placebo-controlled studies have been made to establish whether vitamin C at a dosage of > or = 1 g/day affects the common cold. These studies have not found any consistent evidence that vitamin C supplementation reduces the incidence of the common cold in the general population. Nevertheless, in each of the 21 studies, vitamin C reduced the duration of episodes and the severity o...
