Punjabi, Silver(I) Catalyzed photochemical oxidation of methylene blue
and safranine-O by peroxydisulphate: A green chemical approach, Int.
The mechanism of action of methylene blue
in the treatment of methemoglobinemia is through the NADPH-MetHb reductase system.
Patient was given methylene blue
infusion of 1 mg/kg body weight over 20 mins, SP[O.sub.2] improved to 99% at room air.
The positive result for the presence of AFB was confirmed using ZN technique which includes strong carbol fuschin as primary stain, 20% sulphuric acid as decolorizer and 0.1% methylene blue
as counter stain (7).
The parabasal cells were small round cells with a high nuclear to cytoplasmic ratio and can be seen clearly in clusters when stained with methylene blue
. The intermediate cells varied in size and shape as some can be oval with prominent nucleus and others polygonal with lesser nucleus to cytoplasmic ratio .These cells were clearly shown with the Papanicolaou stain than other stains.
is used for sentinel node biopsies as it carries a lower risk of allergic reaction than the alternative blue dyes (1,2).
Calibration curve were made with methylene blue
solutions at 25, 50, 100, 250, 500 and 1000 mg.[L.sup.-1] concentrations.
Patients were randomly assigned to receive a full dose of the methylene blue
dye, a half dose, or placebo.
For each approach, 1mL plastic syringes filled with 0.2mL of 1% methylene blue
dye were used.
Here, we modeled hindlimb IR by clamping left femoral artery for 4 h followed by 4 h of reperfusion in rats, and the effects of methylene blue
treatment were evaluated.
The methylene blue
has a large polar organic molecule [C.sub.16][H.sub.18][N.sub.3][S.sup.+] that can be adsorbed onto the negatively charged surfaces of clay minerals.
The responses analyzed were the yield and adsorption of methylene blue
. They were related to calcination temperature and time by a second-order polynomial model given in the following equation:
