When using the Mycobacteria Growth Indicator Tube (MGIT), pretreatment of clinical specimens with N-acetyl-L-cysteine-NaOH is recommended by the manufacturer. Processing of clinical specimens (n = 1,000) with sodium dodecyl (lauryl) sulfate-NaOH resulted in both poor recovery and delayed mean time to detection of acid-fast bacilli. Values were comparable to those obtained on solid media.

The purpose of this study is to investigate feasibility of sodium lauryl sulfoacetate (SLS) as an immunoadjuvant in chickens. After treating with 62.5, 125, 250, or 500 mug/mL SLS in vitro, lymphocyte proliferation assay of chicken peripheral blood mononuclear cells showed that the OD(570) values of all experimental groups, as well as Con A-stimulated group, were significantly higher than that ...

Sodium lauryl sulfate (SLS), a synthetic detergent commonly used in dentifrices, is an effective denaturant. The aim of the present study was to investigate the effect of SLS in patients with recurrent aphthous ulcers (RAU). Ten patients with multiple minor RAU participated in the study. The mean incidence of RAU was 17.8 during a 3-month period before the study. The patients used a dentifrice ...

Aim: to prospectively evaluate degree of pain during transrectal ultrasound-guided prostate biopsy after receiving analgesics treatment of oral morphine sulphate compared to suppository sodium diclofenac. Methods: the study group comprised 60 consecutive men subjects (median age 67.8 years) undergoing transrectal prostate biopsy. They were randomized into two groups; group 1 received oral analg...

BACKGROUND In order to develop colloidal drug carriers with desired properties, it is important to determine physico-chemical characteristics of these systems. Bile salt mixed micelles are extensively studied as novel drug delivery systems. The objective of the present investigation is to develop and characterize mixed micelles of nonionic (Triton X-100) or anionic (sodium lauryl ether sulfate)...

Plasmid deoxyribonucleic acid (DNA) ranging from 5 x 10(6) to 65 x 10(6) daltons may be isolated from chromosomal DNA by the preferential precipitation of the higher-molecular-weight chromosomal DNA in the presence of sodium lauryl sulfate and a high concentration of NaCl.

The effect of three chemical formulationstwo surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Dodecyl Benzene Sulfonate (SDBS) and a builder Sodium Tripolyphosphate (STPP) on two aquatic plants – Azolla pinnata and Hydrilla verticillata was studied at various concentrations for a period of five months, from November to March. It was observed that while the detergents favoured the growth of p...

Inhibition of hemolysis by plasma has been studied in systems containing saponin, digitonin, and sodium lauryl sulfate, using the methods developed for the study of the kinetics of progressive reactions. The results are that the progressive nature of the hemolytic reaction in saponin systems becomes less when the inhibitor is added, that the addition of inhibitor to digitonin systems has no eff...
