(17) In microsomes from untreated rats with the predominant cytochrome P450IIA1 subfamily as well as in microsomes from isopropanol treated rats (induction of cytochrome P450IIE1) which catalyse only lonazolac hydroxylation to a detectable amount, the latter reaction was inhibited by pantoprazole with a somewhat lower Ki of 77 whereas the values for omeprazole and lansoprazole remained unchanged in comparison to those found in microsomes from phenobarbital pretreated rats.
(18) Clotrimazole, an imidazole antifungal drug, is known to induce cytochrome P450 isozymes of the P450IIIA and P450IIB subfamilies in rats.

(20) These two subfamilies were further shown not to be present on the homologous chimpanzee chromosomes and therefore must have arisen by rearrangement of the human genome after separation of the two species.
Taxonomic
Definition:
(a.) Pertaining to, or involving, taxonomy, or the laws and principles of classification; classificatory.
Example Sentences:
(1) The taxonomic relationship of strains H4-14 and 25a with previously described Xanthobacter strains was studied by numerical classification.
(2) Bordetella pertussis and Bacillus anthracis, two taxonomically distinct bacteria, secrete adenylate cyclase toxins that are activated by the eukaryotic protein calmodulin.
(3) The present classification of vasculitis has several objections, based on the following aspects: 1) It does not take into account taxonomic rules; 2) It uses criteria which helps to cover up; 3) It uses generic terms without a specific meaning; 4) Lack of clinical interest.
(4) As an extension to the variety of existing techniques using polymorphic DNA markers, the Random Amplified Polymorphic DNA (RAPD) technique may be used in molecular ecology to determine taxonomic identity, assess kinship relationships, analyse mixed genome samples, and create specific probes.
(5) Authors pointed on etiologic connections between particular clinical syndroms in AIDS and microbial, parasitic and viral agents belonging to different taxonomic groups.
(6) Disclosure of the 5'-terminal sequence of the HCV genome would facilitate its taxonomic classification, and contribute toward immunological diagnosis of infection and development of vaccines.
