The psychiatric morbidity following hysterectomy has received increasing attention. One of the sequelae of hysterectomy has been a brief, acute psychosis with excellent outcome, the etiology and pathomechanism of which is still unclear. Two Chinese patients born of Southeast Asian origin who manifested brief, acute psychosis following hysterectomy are presented. Therapy comprised drug treatment with low dose antipsychotics and benzodiazepines coupled with hypnosis and marital therapy to explore and treat the underlying pathology. Both psychotic states resolved.
The in vitro effect of the following antimicrobial agents on Toxoplasma gondii tachyzoites were studied: artemisinin ether (arteether), cycloguanil hydrochloride (cycloguanil), mefloquine, primaquine phosphate, and quinine sulfate, as well as the calcium channel blocker verapamil and the calmodulin inhibitor trifluoperazine hydrochloride. Arteether at > or = 0.5 micrograms/ml and cycloguanil at > or = 1.0 micrograms/ml inhibited T. gondii in vitro. Cycloguanil (2.5 micrograms/ml) combined with a noninhibitory concentration of sulfadiazine (25 micrograms/ml) inhibited T.
Drug Metabolism and Disposition: The Biological Fate of Chemicals
The aim of this study was to investigate the effect of commonly used botanicals on UDP-glucuronosyltransferase (UGT) 1A4, UGT1A6, and UGT1A9 activities in human liver microsomes. The extracts screened were black cohosh, cranberry, echinacea, garlic, ginkgo, ginseng, milk thistle, saw palmetto, and valerian in addition to the green tea catechin epigallocatechin gallate (EGCG).
