P-222: The Effect of Vitex Agnus Castus Essential Oil on Seminiferous Tubule Structure in Mice

Background: Plant materials continue to play an important role in the maintenance of human health since antiquity. Phytoestrogens are naturally occurring plant substances that can either mimic or antagonize the action of endogenous estrogens. This study was conducted to investigate the effects of vitex agnus as a phytoestrogenic plants, essential oil on structure and morphology of seminiferous ...

evidence of active transport involvement in morphine transport via mdckii and mdck-pgp cell lines

several transporters appear to be important in transporting various drugs. many patients, who receive morphine as analgesic medication, also receive other medications with potency of changing morphine transport by affecting p-glycoprotein (p-gp) and oatp2 transport system. this could influence morphine pharmacokinetics and pharmacodynamics. the aim of present study was to elucidate the transpor...

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Ontogeny of rabbit proximal tubule urea permeability.

Urea transport in the proximal tubule is passive and is dependent on the epithelial permeability. The present study examined the maturation of urea permeability (P(urea)) in in vitro perfused proximal convoluted tubules (PCT) and basolateral membrane vesicles (BLMV) from rabbit renal cortex. Urea transport was lower in neonatal than adult PCT at both 37 and 25 degrees C. The PCT P(urea) was als...

Active cellular transport of urea by frog renal tubules.

P KEVIOUS studies have shown that, in the frog, urea is excreted in part by tubular activity. Marshall and Crane in their classic paper on the secretory function of renal tubules (I) emphasized that urea ex-cretion in frogs differed from that in mammals and resembled phenol red elimination in frogs and mammals in that its excretory efficiency (U/P ratio) was depressed as plasma concentrations w...
