Effects of antibiotics on oestrogen metabolism.
SIR,-Ampicillin,1 phenoxymethylpenicillin,2 and neomycin3 have been shown to decrease urinary oestriol output in normal human pregnancy. We have explored this matter further by employing a new gas chromatographic method4 which enables the four known urinary oestriol conjugates to be measured separately. Six healthy mothers 33-37 weeks pregnant were given 0 5 g of ampicillin orally four tines da...
متن کاملEffects of Soil Salinity on Sucrose Metabolism in Cotton Leaves
This study investigated sucrose metabolism of the youngest fully expanded main-stem leaf (MSL) and the subtending leaf of cotton (Gossypium hirsutum L.) boll (LSCB) of salt-tolerant (CCRI-79) and salt-sensitive (Simian 3) cultivars and its relationship to boll weight under low, medium and high soil salinity stress in Dafeng, China, in 2013 and 2014. The results showed that with increased soil s...
متن کاملArsenic Toxicity: The Effects on Plant Metabolism
The two forms of inorganic arsenic, arsenate (AsV) and arsenite (AsIII), are easily taken up by the cells of the plant root. Once in the cell, AsV can be readily converted to AsIII, the more toxic of the two forms. AsV and AsIII both disrupt plant metabolism, but through distinct mechanisms. AsV is a chemical analog of phosphate that can disrupt at least some phosphate-dependent aspects of meta...
متن کاملNovel biopesticide based on a spider venom peptide shows no adverse effects on honeybees
Evidence is accumulating that commonly used pesticides are linked to decline of pollinator populations; adverse effects of three neonicotinoids on bees have led to bans on their use across the European Union. Developing insecticides that pose negligible risks to beneficial organisms such as honeybees is desirable and timely. One strategy is to use recombinant fusion proteins containing neuroact...
متن کاملEffects of oestrogen administration on vitamin B6 and tryptophan metabolism in the rat.
1. In order to assess the effects of oestrogens on the metabolism of tryptophan and vitamin B6, ovariectomized rats have been maintained on diets providing known amounts of tryptophan, nicotinamide and vitamin B6. They received oestrone sulphate, 210 micrograms/kg body-wt per d, either incorporated in the diet for 8 weeks, or by daily intraperitoneal injection for periods of 1-3 d. 2. Oestrone ...
