calcium oxalate/dental caries

We describe the case of a patient with calcium oxalate monohydrate and calcium oxalate dihydrate calculi occluded in cavities. All those calculi were located inside narrow cavities covered with a thin epithelium that permits their visualization. Urinary biochemical analysis showed high calciuria,

Under study were the effects of bacterial stimulation of prepared dentin on dental pulp. Traditional method of drug treatment of prepared cavity with alcohol and either was compared with methods reducing dentin permeability making use of calcium hydroxide, potassium nitrate, and calcium oxalate.

Alocasia macrorrhiza (L) Schott and Endl is called Hai Yu, Tien Ho, Shan Yu, Kuan Yin Lien, Tu Chiao lien, Lao Hu Yu and Lang Du in Chinese. Its common English name is Giant Elephant's Ear. The toxic effects of A macrorrhiza arise from sapotoxin and include gastroenteritis and paralysis of the nerve

Typha angustifolia L. (Typhaceae) is an emergent aquatic plant, and aerenchyma is formed through cell lysis in its leaves. The developing aerenchyma of T. angustifolia contains many CaOx crystals (raphides). Oxalate oxidase (OXO) (oxalate:oxygen oxidoreductase, EC1.2.3.4) can degrades calcium

OBJECTIVE The presence of uric acid in the beginning zone of different types of 'pure' calcium oxalate renal calculi was evaluated with the aim of establishing the degree of participation of uric acid crystals in the formation of such calculi. METHODS The core or fragment of different types of

Urine contains variable amounts of organic matter derived from cell degradation. The cellular detritus is composed by membranous and cytosolic glycoproteins, etc. The aim of this paper was to study the role of organic matter in calcium oxalate crystal development and to evaluate the action of some

To our knowledge, this is the first report of calcium oxalate crystals in a cyst of the oral cavity. No underlying systemic disorder could be identified. It is proposed that this represents a dystrophic process, possibly related to inflammation, although the mechanism of the crystal formation is

Discrimination between aspergilloma and chronic necrotizing pulmonary aspergillosis (CNPA) based on radiological findings can difficult. We describe a patient with aspergilloma and organizing pneumonia that was possibly caused by Aspergillus niger infection and radiologically mimicked CNPA. A

OBJECTIVE The monohydrate calcium oxalate lithiasis (MCO) is divided in two groups depending on the morphologic-crystal structure: papillary (anchorage point on a renal papilla lesion) and cavity (formed in a cavity with low urodynamic capacity). The minimal differences between urinary biochemistry

The patient was a 54-year-old woman who had been suffering from chronic tubulo-interstitial nephritis for about seven years, requiring haemodialysis. More recently, she developed a polypoid mass in the left nasal cavity causing discomfort on breathing and slight epistaxis. The tumour was of gritty

The present study aimed to examine the effect of the histone deacetylase inhibitor, vorinostat (SAHA), on renal function in a calcium oxalate crystal mouse model, and to investigate the mechanism underlying the renoprotective effect of SAHA. Calcium oxalate crystal formation was induced in 8

The inner fine structure of 30 human uroliths composed predominantly of calcium oxalate monohydrate was studied in detail. Each type of stone distinguished on the basis of qualitative parameters, viz. M1, M2, S1 and S2 (see Part I), exhibited a specific and characteristic inner structure different

Formation of calcium oxalate stones tends to increase with age and begins from the attachment of a crystal formed in the cavity of renal tubules to the surface of renal tubular epithelial cells. Though most of the crystals formed in the cavity of renal tubules are discharged as is in the urine, in

Metabolic products of Aspergillus species may play a significant role in the pulmonary destructive process. We describe a patient who died of respiratory failure, in whom postmortem examination revealed aspergilloma and numerous calcium oxalate crystals around the aspergilloma, as well as extensive

In human nephrolithiasis, most stones are containing calcium and are located within urinary cavities; they may contain monohydrate calcium oxalate, dihydrate calcium oxalate and/or calcium phosphates in various proportion. Nephrolithiasis may also be associated with nephrocalcinosis, i.e., crystal
