I60tng/day) due to hepatotoxicity manifested as asymptomatic transaminase elevations, as well as nausea and vomiting, diarrhea, and anorexia. Odier limitations of tacrine, such as a relatively short half-life (2-3 hr) and significant interindividual variation in clearance rates that necessitated drug titration and plasma determinations, motivated the search for novel agents. It is available under the trade name Cognex, but is rarely prescribed. 

Only the unbound fraction of hydrocortisone and the synthetic corticosteroids are biologically active. Generally, the amount of transcortin in the plasma determines the distribution of glucocorticoids between free and bound forms, and free glucocorticoid concentrations determine the drug s half-life. Glucocorticoids cross the placenta and may be distributed into milk. 

In a collaborative trial, two closely similar samples of oil shale (A and B) were sent to 15 laboratories, each of which performed a single inductively coupled plasma determination of the cadmium level in each sample. The following results were obtained ...

Riboflavin absorbed from the intestine is concentrated in the plasma and erythrocytes of circulating blood. The concentration of this vitamin in plasma determined by Hustad et al. (2002) was 74 nM/L for FAD, 10.5 nM/L for riboflavin and 6.6 nM/L for FMN. These results were compatible with the concentrations noted in previous studies (Schrijver et al. 1991). A much higher concentration of vitamin B2 forms (4-5 times) is present in the interior of erythrocytes. The dominant fraction of vitamin B2 in erythrocytes is also FAD ( 470 nM/L) and FMN ( 45 nM/L), and only a trace amount of free riboflavin is detected (Hustad et al. 2002). After supplementation, the strongest increase in free riboflavin (83%) and FMN (87%) is observed in plasma and erythrocytes, respectively. The level of flavins in erythrocytes is less dependent on short-term dietary intake of riboflavin compared with the plasma level.
