OBJECTIVE To examine the prevalence and risk factors of vitamin deficiencies among older Thai adults. METHODS The cross-sectional study was conducted in four rural communities, one from each of the four main regions of Thailand. In total, 2336 subjects aged 60 years and over were recruited. Anthropometric variables, demographic data, blood glucose and lipid profile, albumin, globulin and bloo...

IN a quantitative study of the excretion of vitamin B1 in human urine [Harris & Leong, 1936], it was observed that, with the subjects studied, the daily urinary output of the vitamin amounted to only about 10% of the daily intake. Later, in a more detailed study on rats [Leong, 1937], evidence was obtained that a certain amount of the ingested vitamin could not be accounted for in the total uri...

1. The effect of vitamin B complex (vitamin B1, B6 and B12) was studied on nerve conduction velocity in acrylamide-neuropathy rats maintained on refined semisynthetic complete vitamin and vitamin B-deficient diets in vivo and on neurite outgrowth in vitro using cells obtained from dorsal root ganglions of mice. 2. Acrylamide neuropathy was clearer in the group maintained on a refined semisynthe...

Background and aim: Primary dysmenorrhea is defined as painful menstruation in the absence of any confirmed pelvic disease. Its incidence has been estimated between 50-90% in different communities. Non-steroidal anti-inflammatory drugs (NSAIDs) and contraceptives are usually prescribed for the treatment of primary dysmenorrhea; however, they cause several specific complications. Due to the impo...

Fungus growth methods for estimating either vitamin B1 thiazole or vitamin B1 pyrimidinel have been used by Robbins and Kavanagh (l), Kavanagh (2), and Krampitz and Woolley (3), and a fermentation stimulation method has been described by Schultz, Atkin, and Frey (4). A procedure utilizing the synthesis of vitamin B1 by yeast from thiazole and pyrimidine has been used in this laboratory to estim...

The purpose of the present study was to examine the nutritional status of vitamin B1, B2, and B6 in respect to dietary intake of these vitamins and activity coefficients of the erythrocyte enzymes transketolase, glutathione reductase, and aspartic aminotransferase in young men and women with different physical activity levels. The participants of this study were 20 women and 20 men with high ph...

Case: We describe a case of beriberi with leg edema, pleural effusion, and anemia. Echocardiography revealed that the inferior vena cava diameter was 18 mm, but respiratory changes were not observed. Pulmonary hypertension was observed, with a systolic pulmonary arterial pressure of 45 mmHg. Peripheral blood concentrations of vitamin B1 decreased significantly. Beriberi heart disease caused by ...

Vitamin B1, or thiamin, can limit primary productivity in marine environments, however the major marine environmental sources of this essential coenzyme remain largely unknown. Vitamin B1 can only be produced by organisms that possess its complete synthesis pathway, while other organisms meet their cellular B1 quota by scavenging the coenzyme from exogenous sources. Due to high bacterial cell d...

IT was shown by Coward [1933] that the accuracy obtainable in a vitamin A test by the "increase in weight" method was increased very little by prolonging the test period beyond three weeks. Since then, enough results of vitamin B1 determinations by the method of the "increase in weight" of rats have been accumulated to make it possible to carry out a similarexamination ofthe duration of a vitam...
