Comparative Studies on Respiration. Xv. the Effect of Bile Salts and of Saponin upon Respiration
I t was pointed out by Osterhout I that substances which increase the electrical conductivity of tissues are antagonized by those which decrease it. An illustration of this is seen in antagonism between NaC1 (which increases conductivity) and Na taurocholate ~ (which decreases it). This case has additional interest as an example of antagonism between anions as well as of antagonism between orga...
متن کاملThe Acceleration of Saponin Hemolysis by Proflavine
Proflavine is a very powerful accelerator of saponin hemolysis of rabbit, human, and dog erythrocytes. Lysolecithin hemolysis, on the other hand, is inhibited. Dog erythrocytes in the presence of proflavine undergo marked changes in shape, finally becoming rods of about 13 micro in length. Rabbit and human erythrocytes are not altered in form under these conditions.
متن کاملCr Secretion Induced by Bile Salts
When applied to the basolateral (serosal) side of the T84 coIonic epithelial monolayer, taurodeoxycholate caused net Clsecretion in a dose-dependent manner with a threshold effect observed at 0.2 mM. In contrast, when applied to the apical (luminal) surface, concentrations of taurodeoxycholate below 1 mM had little or no effect. Only when the concentration of taurodeoxycholate present on the ap...
متن کاملBile salts modulate chronic ethanol-induced hepatotoxicity.
This study tested the hypothesis that chronic ethanol-induced injury in rats may be modified by the hydrophobicity of the bile acid pool. The supplementation to chronic ethanol feeding (28 days) with chenodeoxycholate, a hydrophobic bile salt, aggravated steatosis (accumulation of triacylglycerols and cholesterol esters), lipoperoxidation and cytolysis (expressed as elevations of activities of ...
متن کاملEffects of Bile and Bile Salts
We have shown previously that ox and pig bile accelerate in vitro growth of Giardia lamblia. We have now investigated the possible mechanisms by which mammalian biles promote parasite growth. Growth effects of (a) ox, pig, guinea pig, and human biles, (b) pure bile salts, and (c) egg and soybean lecithins were studied in the presence of a lecithin-containing growth medium. Individually, dilute ...
