Spectrophotometric Studies of Penetration of Dyes
Spectrophotometric measurements show that the non-medullated nerve of a lobster claw is capable of absorbing methylene blue, azure B, or acid fuchsin dissolved in sea water but this does not necessarily imply that the dyes penetrate into the interior of the nerve.
متن کاملSTUDIES ON PENETRATION OF DYES WITH GLASS ELECTRODE V. WHY DOES AZURE B PElq'ETRATE MORE READILY THAN METHYLENE BLUE OR CRYSTAL VIOLET? BY MARIAN IRWIN
The results 1 from measurements made with the glass electrode and spectrophotometer show that brilliant cresyl blue penetrates as free base into the vacuoles of living cells of Nitella. The present paper describes similar experiments with azure B, methylene blue, and crystal violet. Since the methods for the condition of cells, extraction of the sap, penetration experiments, extraction of free ...

"Previous studies showed that repeated ingestion of erythrosine B [Red 3] (artificial food color) developed behavioral hyperactivity, but nothing is known about its single administration effect as well as the neurochemical (s) involvement. ... The degree of erythrosine-induced inhibition of both MA [motor activity] and brain regional serotonergic activity was dosage dependent. ... Altogether th...
متن کاملEffects of Ct Injector Acceleration Electrode Configuration on Tokamak Penetration
Through compact toroid (CT) injection experiments on the TEXT-U tokamak (with BT ' 10 kG and IP ' 100 kA), it has been shown that the acceleration electrode configuration, particularly in the vicinity of the toroidal field (TF) coils of the tokamak, has a strong effect on penetration performance. In initial experiments, premature stopping of CTs within the injector was seen at anomalously low T...
متن کاملSpectrophotometric Studies of Penetration
The rate of diffusion through the non-aqueous layer of the protoplasm depends largely on the partition coefficients mentioned above. Since these cannot be determined we have employed an artificial system in which chloroform is used in place of the non-aqueous layer of the protoplasm. The partition coefficients may be roughly determined by shaking up the aqueous solutions with chloroform and ana...
