Zoxazolamine paralysis times have been used as a probe to measure the activities of cytochrome P450 1A1 in mice in vivo. The results indicate that male and female mice of the BALB/c and CBA/J strain do not show altered paralysis times if infected with less than 4 worm pairs. Alterations were observed only in animals harbouring more than 5 worm pairs irrespective of the sex or strain of mouse being used. The study has extended the findings of other workers showing that mice infected with fewer than 4-5 worm pairs of S. mansoni do not show any alteration in the metabolism of pentobarbital in vivo.

D010243	Paralysis	A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function.

D003577	Cytochrome P-450 Enzyme System	A superfamily of hundreds of closely related HEMEPROTEINS found throughout the phylogenetic spectrum, from animals, plants, fungi, to bacteria. They include numerous complex monooxygenases (MIXED FUNCTION OXYGENASES). In animals, these P-450 enzymes serve two major functions: (1) biosynthesis of steroids, fatty acids, and bile acids; (2) metabolism of endogenous and a wide variety of exogenous substrates, such as toxins and drugs (BIOTRANSFORMATION). They are classified, according to their sequence similarities rather than functions, into CYP gene families (>40% homology) and subfamilies (>59% homology). For example, enzymes from the CYP1, CYP2, and CYP3 gene families are responsible for most drug metabolism.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D012550	Schistosoma mansoni	A species of trematode blood flukes of the family Schistosomatidae. It is common in the Nile delta. The intermediate host is the planorbid snail. This parasite causes schistosomiasis mansoni and intestinal bilharziasis.	Schistosoma mansonus,mansonus, Schistosoma
