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...

The aim of the present study was to assess the effects of ammonium sulphate exposure on the antioxidant defence system and lipid peroxide concentration in the testes of wistar rats, as well as the examine possible protective role of zinc from the adverse effects of ammonia .The LD50 of Ammonium Sulphate and Zinc Chloride were determined, after toxicity testing evaluation. It is 91.5 mg/kg body ...

The effects of inhaled zinc oxide/hexachloroethane smoke (11,580 mg x min/m3) and intratracheally instilled zinc chloride (2.5 mg/kg body weight) have been studied in rat lung. The effects of subsequent treatment with 70% oxygen have been studied after both procedures. Both the inhalation of the smoke and instillation of zinc chloride produced similar effects that included pulmonary edema, alve...

Degenerative histopathalogical alterations were seen in liver due to chronic exposure of the fish, Labeo rohita to chlorides of chromium, nickel and zinc for 30 days. However, more severe degenerative changes were observed in case of zinc chloride exposed fish than nickel chloride and chromium chloride treated fishes, indicating more toxic nature of zinc chloride. There were enlarged nuclei, co...

BACKGROUND Ellagic acid (EA), a dietary polyphenolic compound, has been demonstrated to exert anti-angiogenic effect but the detailed mechanism is not yet fully understood. The aim of this study was to investigate whether the zinc chelating activity of EA contributed to its anti-angiogenic effect. METHODS AND PRINCIPAL FINDINGS The matrix metalloproteinases-2 (MMP-2) activity, a zinc-required...

background: since heavy metals can accumulate in the tissues of aquatic organisms, they can cause a range of hazardous effects which can become harmful to humans. the aim of this study was to investigate the acute effects of some heavy metals as potential dangerous substances by assessing the mortality effects of mercuric chloride (hgcl2), lead chloride (pbcl2) and zinc sulfate (znso4) pollutan...

Other studies avoided the use of a zinc salt by generating lithium zincates either by iodine-metal exchange 7 or by deprotonation. 8 In 2002, Gauthier and co-workers documented an approach through lithium zincates using only one third equivalent of zinc chloride for the synthesis of 5-aryl-2-furaldehydes from 5-lithio-2-furaldehyde diethyl acetal. 9 In addition, Mutule and Suma described in 200...
