AIM To evaluate the effect of different mouth rinses 12 h after rinsing on genuine intra-oral halitosis. MATERIALS AND METHODS Twenty-four adults with halitosis were included in a double-blind, crossover, randomized clinical trial. Halitosis was evaluated 12 h after rinsing with placebo and five mouth rinse products containing zinc acetate and chlorhexidine diacetate; zinc lactate, chlorhexid...

595 Abstract: The antibacterial activity of zinc acetate against Staphylococcus auerus, Staphylococcus epidermidis and Pseudomonas aeruginosa isolates was measured in Mueller-Hinton broth containing different amounts of zinc acetate using spectrophotometry. Staphylococcus auerus, Staphylococcus epidermidis and Pseudomonas aeruginosa isolates were inhibited by zinc acetate (p<0.05). The effect o...

The glycolysis of postconsumer polyethylene terephthalate (PET) waste was evaluated with catalysts of zinc acetate, zinc stearate and zinc sulfate, showing that zinc acetate was the most soluble and effective. The chemical recycling by solvolysis of polylactic acid (PLA) and PET waste in either methanol or ethanol was investigated. Zinc acetate as a catalyst was found to be necessary to yield a...

BACKGROUND Repeated use, coitus-independent microbicide gels that do not contain antiretroviral agents also used as first line HIV therapy are urgently needed to curb HIV spread. Current formulations require high doses (millimolar range) of antiretroviral drugs and typically only provide short-term protection in macaques. We used the macaque model to test the efficacy of a novel combination mic...

BACKGROUND A previous meta-analysis of 3 zinc acetate lozenge trials estimated that colds were on average 40% shorter for the zinc groups. However, the duration of colds is a time outcome, and survival analysis may be a more informative approach. The objective of this individual patient data (IPD) meta-analysis was to estimate the effect of zinc acetate lozenges on the rate of recovery from col...

Sir—Upon reviewing the recently published report by Turner et al. [1] about the effects of zinc gluconate or zinc acetate lozenges on experimental and natural rhinovirus colds, I realized that I have some information that was inadvertently omitted and that is necessary to accurately discern the meaning of the report. As a zinc ion availability (ZIA) consultant for Warner Lambert, I found that t...

BACKGROUND A previous meta-analysis found that high dose zinc acetate lozenges reduced the duration of common colds by 42%, whereas low zinc doses had no effect. Lozenges are dissolved in the pharyngeal region, thus there might be some difference in the effect of zinc lozenges on the duration of respiratory symptoms in the pharyngeal region compared with the nasal region. The objective of this ...

Intracellular levels of zinc have shown a strong inverse correlation to growth and malignancy of prostate cancer. To date, studies of zinc supplementation in prostate cancer have been equivocal and have not accounted for bioavailability of zinc. Therefore, we hypothesized that direct intra-tumoral injection of zinc could impact prostate cancer growth. In this study, we evaluated the cytotoxic p...

AIMS The aim of this study was to determine whether the allergy status and other characteristics of common cold patients modify the effects of zinc acetate lozenges. METHODS We had available individual patient data for three randomized placebo-controlled trials in which zinc acetate lozenges were administered to common cold patients. We used both one stage and two stage meta-analysis to estim...
