Five varieties of cowpea (Vigna unguiculata) were analysed for their proximate composition, major mineral elements and carbohydrate fractions. Values crude protein ranged from 25.80% to 28.95% while the ether extract, fibre, total ash had following values: 1.83 - 2.37%, 3.06 4.48%, 5.80 7.10% 50.46 55.76% respectively. The average values phosphorus, calcium, magnesium, potassium sodium 0.400%, ...

Sodium taurolithocholate and sodium taurocholenate were infused intravenously into rats and hamsters. Each bile acid salt was given alone or in combination with varying amounts of a primary bile salt, either sodium taurocholate or sodium taurochenodeoxycholate. Bile flow, total bile acid salt excretion, and the excretion of sodium taurolithocholate were quantitatively determined. In addition, m...

The effect of soluble fluorine species in different concentrations on the catabolic activity of Desulfotomaculum ruminis bacteria has been studied. The fluoride concentrations tolerated by and toxic to the bacteria have been determined. The degree of fluorine species toxicity was found to depend on the form in which fluorine is introduced into the medium and increases in the following order: Na...

Insulin increases active sodium transport by the toad urinary bladder within 15 min, an effect which persists for an least 20 h. In tissues pre-treated with inhibitors of transcription or translation, sodium transport briefly increases after insulin addition but returns to basal levels within 60-90 min. We have studied the effects of insulin on the incorporation of radioactive amino acids into ...

Wheat straw-g-polyacrylonitrile (PAN), containing 40% PAN, was saponified with sodium hydroxide and isolated under three sets ofsaponification and work-up conditions. Each reaction mixture was separated into a water-soluble and a water-insoluble fraction, which were individually analyzed for percentages (by weight) of synthetic polymer (saponified PAN), cellulose, hemicellulose, and lignin. Wat...

1. Strontium absorption was studied in vivo with loops of ileum in rachitic chicks and found to be increased by vitamin D(3), bile salts and sodium lauryl sulphate. 2. Bile salts and sodium lauryl sulphate rendered strontium soluble in butanol-benzene (1:1, v/v). 3. Bile was not concerned in the absorption of iron in rats from its water-soluble form, ferrous sulphate. 4. Ligation of the bile du...

Soluble salts, nutrients, and pathogenic bacteria in feedlot-pen runoff have the potential to cause pollution of the environment. A 2-yr study (1998-1999) was conducted at a beef cattle (Bos taurus) feedlot in southern Alberta, Canada, to determine the effect of bedding material [barley (Hordeum vulgare L.) straw versus wood chips] and within-pen location on the chemical and bacterial propertie...

Para-aminosalicylic acid (PAS) is now generally accepted as an effective antibacterial agent in the treatment of certain forms of tuberculosis when administered alone or in combination with one of the streptomycins. However, there remains a great deal of uncertainty as to the best method of administering the drug. Both the free acid and the sodium salt of PAS have been given in various dosage f...

We have established a simple method for assaying the quantity of soluble bromine in the discharge tubes of an extra-high-pressure mercury discharge lamp. Each discharge tube is destroyed in 5 ml of 10 mM sodium hydroxide, and the recovered sodium hydroxide solution is analyzed by suppressed-ion chromatography using gradient elution. We have clarified that this method can assay less than 1 micro...
