In recent years we have attempted to produce pigs 3-5 weeks old deficient in vitamin BIZ. The pigs were removed from the sow at 2 days of age and reared on a vitamin B,,-deficient synthetic-milk diet of the composition described by Neumann, Johnson & Thiersch (1950). Unlike the American workers, we were unable to produce such deficient pigs under our conditions and considered that differences i...

In many diseases such as cancer, simultaneous use of two or more pharmacologically active agents will be more effective and have fewer side effects. In this study a new palladium(II) complex with formula of [Pd(phen)(py-dtc)]NO3 (where is phen 1,10-phenanthroline and py-dtc is n-propyldithiocarbamate), was synthesized. The cytotoxic activity of this complex was tested against leukemia K562 cell...

1. A study was undertaken to investigate the role of vitamin E in the aetiology of phrynoderma (follicular hyperkeratosis). Fifty-six children with the disease and twenty-one normal children were investigated for this purpose. 2. Plasma vitamin E levels (mean +/- SE; mg/l) were found to be low in phrynoderma (3.7 +/- 0.19) in contrast with normal children (6.6 +/- 0.40) and therapy with a combi...

Consumption of vegetables and fruits is associated with a reduced risk of stroke, but it is unclear whether their protective effects are due to antioxidant vitamins or folate and metabolically related B vitamins. The purpose of the study was to test the hypothesis that intake of fruits and vegetables, which are major sources of antioxidant and vitamin B complex vitamins, reduces the risk of str...

B complex vitamins play an important role in the metabolism of carbohydrates, proteins and fats. The aim of this study was to determine the effects of B complex vitamins administered by exogenous route on rumen protozoa, hematological and blood biochemical parameters in clinically healthy cattles. Thirty cattles aged between 6 to 18 months, and breeding in Afyonkarahisar Province and surroundin...

Pyridoxineless mutants of Escherichia coli B which specifically require pyridoxal or pyridoxamine for growth can be divided into classes according to their growth responses in enriched media. Members of the slowest growing class synthesize vitamin B(6) at the fastest rates when starved for pyridoxal in glycerol minimal medium. After 80 min of synthesis at 4 x 10(-10) moles of vitamin B(6) per m...
