objective: in order to overcome the limitation of systemic administration of methylene blue, this study investigated the encapsulation of methylene blue in polymeric liposomes and drug release following sonication. methods: we encapsulated methylene blue into nanoliposomes. the dynamic light scattering (dls) method was used to measure the size distribution of the liposomes. after loading methyl...

The authors recently demonstrated that methylene blue (MB), an inhibitor of the nitric oxide (NO) pathway, reduces the increments in pulmonary capillary pressure, lung lymph flow and protein clearance in endotoxaemic sheep. In the present study, the authors examined whether MB influences pulmonary haemodynamics and accumulation of extravascular lung water (EVLW) by mechanisms other than the NO ...

Adsorption of Chromium ions (VI) and (III) in aqueous solution was investigated using activated carbon prepared from olive wastes, by one step physical activation with steam. After adsorbent material characterization using adsorption capacity of methylene blue, iodine and phenol, BET surface area, Fourier Transform InfraRed (FT-IR) spectroscopy, pHpzc, surface functions based on the Boehm m...

Variamine blue dye as chromogenic reagent was used for Portland cement samples in determination of soluble hexavalent chromium. This method was based on the reaction of Cr(VI) with potassium iodide in acidic medium to liberate iodine, which oxidized variamine blue to form a violet colored species having an absorption maximum 556 nm. The extraction of soluble Cr(VI) for quantification in cement ...

Peritoneal adhesions are challenging in abdominal surgery. In spite of different kinds of treatments still no definitive and effective treatment is suggested. To determine the prevention effects of intraperitoneal (ip) methylene blue in post surgical adhesion formation 44 rabbits were randomly divided in two groups of equal number. Group I received an intra peritoneal injection of a 1% suspensi...

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

the effects of thiamine, ascorbic acid ami their combination an workers who are continuously exposal to lead has been investigated. in this study 60 persons in a battery industry was selected and divided into four equal groups. group i received placebo, group ii thiamine (300 mg), group iii ascorbic acid (250 mg) anil group iv thiamine (300 mg) plus ascorbic acid (250 mg) three times a day (ora...

Harvesting lymph nodes (LNs) after gastrectomy is essential for accurate staging. This trial evaluated the efficiency and quality of a conventional method and a methylene blue-assisted method in a randomized manner. The key eligibility criteria were as follows: (i) histologically proven adenocarcinoma of the stomach; (ii) clinical stage I-III; (iii) R0 resection planned by gastrectomy with D1+ ...

       This study was designed to explore the protective effects of ascorbic acid and water extract of Spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. This in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates....

BACKGROUND/AIMS Postoperative adhesions following abdominopelvic surgery may cause significant morbidity. In this study, the effect of different doses of methylene blue in the formation of adhesions and the role of allopurinol in revealing the possible mechanism of action was evaluated. METHODS Seventy five male Wistar-Albino rats weighing 200g-220g. were divided into five groups of 15 rats e...
