Disease relevance of ZINC OXIDE

• Zinc oxide protects cultured enterocytes from the damage induced by Escherichia coli [1].
• There is some evidence that zinc oxide (ZnO) protects against intestinal diseases [1].
• Biometry and primary angle-closure glaucoma among Chinese, white, and black populations [2].
• Pulmonary toxicity of zinc oxide (ZnO) was evaluated by investigating the metabolic fate and inflammatory potency of ZnO instilled into the rat lung [3].
• The potential eco-toxicity of nanosized titanium dioxide (TiO(2)), silicon dioxide (SiO(2)), and zinc oxide (ZnO) water suspensions was investigated using Gram-positive Bacillus subtilis and Gram-negative Escherichia coli as test organisms [4].

High impact information on ZINC OXIDE

• CONCLUSIONS: Zinc oxide welding fume was associated with a marked dose-dependent increase in the number of polymorphonuclear leukocytes recovered in bronchoalveolar lavage fluid 22 hours after exposure but was not associated with a clinically significant change in pulmonary function or airway reactivity [5].
• Detailed XRD, TEM, and Raman studies prove that, with the exception of the iron oxide system, where a mixture of the two phases magnetite and maghemite is formed, only phase pure materials are obtained, gamma-Ga(2)O(3), zincite ZnO, and cubic In(2)O(3) [6].
• RATIONALE: Zinc oxide is a common, biologically active constituent of particulate air pollution as well as a workplace toxin [7].
• Reactions on a solid surface. A simple, economical and efficient Friedel-Crafts acylation reaction over zinc oxide (ZnO) as a new catalyst [8].
• Snow-white duodenum: a new endoscopic sign in a patient with hypobetalipoproteinemia [9].

Biological context of ZINC OXIDE

• Commercial sources of zinc oxide (ZnO) differ widely in Zn relative bioavailability (RBV), but it is unknown whether growth-promoting efficacy in young pigs is influenced by RBV of the ZnO sources used [10].
• 1. The OPAE random primers (Operon Technologies, Inc., CA) were used for random amplified polymorphic DNA (RAPD) fingerprinting in Chinese, White Roman and Landaise geese [11].
• Zinc oxide inhalation causes metal fume fever, a flu-like syndrome common among welders [12].
• Occupational exposure to freshly formed zinc oxide (ZnO) particles (less than 1.0 micron aerodynamic diameter) produces a well-characterized response known as metal fume fever [13].
• Zinc oxide was selected to control the reactivity of the glass-ceramics since zinc is a trace element that shows stimulatory effects on bone formation [14].

Anatomical context of ZINC OXIDE

• It has been reported that zinc oxide (ZnO) inhibits dentine demineralization [15].
• The materials tested--Tubliseal, Diaket, AH26, Nogenol, Roth, and Endomethasone sealers--were placed in root canals with laterally condensed gutta-percha [16].
• Gutta-percha with one of the following sealers--EWT, AH26, Nogenol, or no sealer (control)--was used to fill the root canals of 160 autoclaved incisor and premolar tooth roots [17].

Associations of ZINC OXIDE with other chemical compounds

• The experimental group contained six different types of root canal filling materials, including zinc oxide (ZnO) + eugenol + formocresol (FC), Ca(OH)(2) + FC, Ca(OH)(2) + Iodoform, Ca(OH)(2) + Iodoform + camphorated parachlorophenol (CPC), Ca(OH)(2) + CPC, and Vitapex [18].
• The present pilot study was conducted on five primary mandibular second molars requiring endodontic treatment to evaluate the clinical and radiographic success of root canal filling material which was a mixture of calcium hydroxide paste (1 cm), Zinc oxide powder (15 gms) and distilled water using hand operated lentulo spirals [19].

Gene context of ZINC OXIDE

• Zinc oxide exposure in vitro led to TNF release in a dose-dependent manner at 3, 8, and 24 hours (analysis of variance [ANOVA] P = 0.0001) [20].
• Zinc oxide increased (P < 0.05) ADG, ADFI, and G:F from d 0 to 10, and ADG and ADFI from d 10 to 24 [21].
• The results indicated that red cabbage and mustard cabbage had the highest total antioxidant activity, while Chinese white cabbage and red cabbage had the highest free radical scavenging activity [22].
• METHODS: Urine specimens were collected from Chinese, white American, and African-American women with IC and age and race-matched asymptomatic normal control women [23].
• The metallothionein (MT) content in hairless mouse skin was determined after topical application of various glucocorticoids or zinc oxide (ZnO) [24].

Analytical, diagnostic and therapeutic context of ZINC OXIDE

• Zinc oxide was not associated with increased pain by the visual analog scale, cellular abnormalities by histopathological examination of wound biopsies, or other harmful effects [25].
• On the basis of the study results, it may be concluded that Nogenol appears to be more appropriate for cementation of both 2- and 4-implant-supported FPDs when removal of the provisionally cemented superstructure is anticipated [26].
• Piezoelectric thin film zinc oxide (ZnO) and its ternary alloy magnesium zinc oxide (MgxZn1-xO) have broad applications in transducers, resonators, and filters [27].
• Zinc oxide installed in the tissue cages created high, sustained concentrations of zinc in the cage fluid throughout the study [28].
• CONCLUSIONS: Under the conditions of the present study, Snow-White impression plaster appears to be safer to use in implant prosthodontics compared with the Xantano because of its slower and lower exothermic reaction at the implant-bone interface [29].
