Lawsonia inermis - an alternative treatment for hyperthyroidism?

PubMedID: 24601697Aim: The goal of our study was to determine the effects of Lawsonia inermis (L. inermis) in mice, in which hyperthyroidism had been caused by thyroid stimulant hormone (TSH). Material and method: The first phase of the study aimed to detect the effects of L. inermis on the amount of ionized hydrogen (pH) in cells. For this aim, the effect of L. inermis on pH levels in the liver tissues of mice, in whom Escherichia coli (E. coli) had caused peritonitis, was examined. In the second phase of the study, the effect of L. inermis on the serum T4 levels in the 24th and 48th hour in mice, whose thyroid cells showed an increased activity by TSH was measured. Results: In the first phase, in mice, in whom E.coli had caused peritonitis, the pH in the liver tissue of the group that had been given L. inermis was found to be signifi cantly alkaline (p<0.05). In the second phase, in mice, in whom TSH had caused hyperthyroidism, it was noted that serum total T4 levels were signifi cantly lower than in the group that had been given L. inermis in the 48th hour (p<0.05). Conclusion: In our study, we detected that L. inermis signifi cantly decreased serum total T4 levels in the 48th hour in mice in whom TSH had caused hyperthyroidism. These results suggest that L. inermis can be used as an alternative treatment for the Graves' disease (Tab. 2, Fig. 1, Ref. 34). Text in PDF www.elis.sk

Environmentally friendly system for the degradation of multipesticide residues in aqueous media by the fenton’s reaction

A Fenton oxidation system employing zero-valent iron (whose source was swarf, a residue of metallurgical industries, in powder form) and hydrogen peroxide for the treatment of an aqueous solution with six pesticides was developed, and the effect of the iron metal content, pH, and hydrogen peroxide concentration was evaluated. The characterization of the aqueous solution resulted in: pH 5.6, 105 mg L−1 of dissolved organic carbon, and 44.6 NTU turbidity. In addition, the characterization of the swarf by FAAS and ICP-MS showed 98.43±7.40 % of zero-valent iron. The removal was strongly affected by the content of iron metal, pH, and hydrogen peroxide concentration. The best degradation conditions were 2.0 g swarf, pH 2.0, and 5 mmol L−1 H2O2. At the end of the treatment, the pesticide degradation ranged from 60 to 100 %, leading to 55 % mineralization. Besides, all hydrogen peroxide was consumed and the determination of total dissolved iron resulted in2mgL−1. Thus, the advantages of this system are rapid degradation (up to 20 min), high-degradation rates, simple handling, and low cost
