Previous studies on animals have revealed that garlic (Allium sativum) is effective in reducing blood and tissue lead concentrations. The aim of this study was to investigate therapeutic effects of garlic and compare it with D-penicillamine in patients with chronic lead poisoning. After coordination and obtaining informed consent, clinical examinations and blood lead concentration (BLC) of 117 workers at a car battery industry were investigated. BLC was determined by heated graphite atomization technique of an atomic absorption spectrometer. The workers were randomly assigned into two groups of garlic (1200 lg allicin, three times daily) and D-penicillamine (250 mg, three times daily) and treated for 4 weeks. BLC was determined again 10 days post-treatment. Clinical signs and symptoms of lead poisoning were also investigated and compared with the initial findings. Clinical improvement was significant in a number of clinical manifestations including irritability (p = 0.031), headache (p = 0.028), decreased deep tendon reflex (p = 0.019) and mean systolic blood pressure (0.021) after treatment with garlic, but not D-penicillamine. BLCs were reduced significantly (p = 0.002 and p = 0.025) from 426.32 € 185.128 to 347.34 € 121.056 lg ⁄ L and from 417. 47 € 192.54 to 315.76 € 140.00 lg ⁄ L in the garlic and D-penicillamine groups, respectively, with no significant difference (p = 0.892) between the two groups. The frequency of side effects was significantly (p = 0.023) higher in D-penicillamine than in the garlic group. Thus, garlic seems safer clinically and as effective as D-penicillamine. Therefore, garlic can be recommended for the treatment of mild-to-moderate lead poisoning.
Background:
Multiple sclerosis is the most prevalent neurological disability of young adults. Anti-inflammatory drugs have relative effects on MS. The anti-inflammatory and antioxidative effects of
Zingiber officinale
(ginger) have been proven in some experimental and clinical investigations. The aim of this study was to evaluate the effects of ginger extract on preventing myelin degradation in a rat model of MS.
Methods:
Forty nine male Wistar rats were used in this study and divided into four control groups: the normal group, cuprizone-induced group, sham group (CPZ + NaCMC), standard control group (fingolimod + cuprizone), including three experimental groups of CPZ, each receiving three different doses of ginger extract: 150, 300, and 600mg/kg /kg/day.
Results:
Ginger extract of 600 mg/kg prevented CC from demyelination; however, a significant difference was observed in the fingolimod group (p < 0.05). Difference in the CPZ group was quite significant (p < 0.05).
Conclusion:
Treatment with ginger inhibited demyelination and alleviated remyelination of corpus callosum in rats. Therefore, it could serve as a therapeutic agent in the MS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
