Abstract:
Possible interferences with aflatoxin B1 metabolism, of some compounds naturally present in food (quercetin, beta-naphthoflavone), resulting from way of cooking method (2-aminodipyrido [1,2-a; 1',2'-d] imidazole (Glu-P-2), norharmane; NH) or used as food additives (butylated hydroxytoluene; BHT) have been studied in vivo by evaluating the production of adducts to glutathione and adducts to serum proteins in laboratory rats. Glu-P-2 and norharmane inhibit strongly the production of adducts to glutathione whereas quercetin and beta-naphthoflavone have only a low effect. BHT is completely ineffective. The adducts to proteins are inhibited by the five compounds, norharmane being the most efficient.

Methods for Studying Drug Absorption: In vitro
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...
Methods for Studying Drug Absorption: In situ
The Doluisio method involves perfusing a prepared segment of a rat's small intestine with a solution of radiolabeled drug and a non-absorbable marker. This helps to differentiate between absorbed and non-absorbed drug concentrations. The intestinal segment is connected at both ends using tubing and syringes,...

Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
