1. Chronic renal failure was induced in rats by surgical removal of thirteen-sixteenths of renal tissue. 2. The metabolism of p-amino[14C]benzoic acid was studied in the isolated perfused livers of control and chronically uraemic rats. There was a slower rate of clearance and decreased overall metabolism of the compounds in the uraemic rats. 3. Conjugation of p-amino[14C]benzoic acid with glyci...

over the past decade, the chemical behavior of flavonoids as antioxidants has become the subject ofintense experimental research. in this paper, we use a quantum-chemical approach to shed light on thereactivity of four poly phenols, benzoic acid, vanilic acid, gallic acid and flavone . in order to establishthe most efficient theoretical methodology, different methods, either hartree—fock-based ...

A straightforward synthesis of phenols from aryl boronic acids has been demonstrated using benzoic acid as a catalyst. Variety arylboronic bearing electron rich and withdrawing substituents gave the respective in good yields.

The reaction of lead acetate, benzoic acid and 2,2'-bipyridine (bipy) in aqueous solution yielded the title complex, [Pb(C(7)H(5)O(2))(2)(C(10)H(8)N(2))]·C(7)H(6)O(2). The asymmetric unit contains two independent complex mol-ecules as well as two independent benzoic acid solvent mol-ecules, one of which is disordered over two positions with almost equal occupancies [0.504 (5) and 0.496 (5)]. Th...

The purpose of this study was to assess the efficacy of a probiotic containing Bacillus cereus var. Toyoi spores (Toyocerin) and benzoic acid (VevoVitall) on growth performance and diarrhoea in weaning pigs, against negative controls. The trial groups were as follows: (a) NC group (Negative Controls): No treatment (b) TOYO group: Same feed as in the controls plus Toyocerin at a dose of 1 x 10(9...

I. S 24 perennial ryegrass was harvested at six stages of its growth from young leafy herbage to mature grass in which the seed had shed. 2. Two sheep were offered Ikg/d of each cut and two other sheep were offered 750 g/d of each cut of grass. 3. The contents of some possible precursors of the urinary aromatic acids excreted by sheep, namely, shikimic acid, quinic acid, chlorogenic acid, total...
