Chemical Content Variations and Morphological Changes Evaluation of Incisors Enamel Induced by Chronic Fluoride Intoxication

The aim of this study was to assess the morphology and chemical composition changes induced by chronic intoxication with low doses of sodium fluoride (NaF) in mice enamel. Twenty-one C57BL/6 male mice of the same age were randomly divided into a control group and 2 experimental groups (n = 7). The experimental groups were treated with 25ppm and 50ppm respectively of NaF. NaF was supplied throug...

Chronic chloroform intoxication.

Chloroform was discovered in 1831 by a French chemist, Soubeiran, and independently by the American, Samuel Guthrie of Sachett's Harbour, in the State ofNew York (Duncum, 1947). Soubeiran obtained impure chloroform, which he provisionally called " bichloric ether ", by distilling a mixture of chloride of lime and alcohol. Liebig, in the following year, obtained a purer chloroform, which he name...

Chronic lead intoxication mimicking motor neurone disease.

a sexual contact by gonorrhoea patients is a valid candidate for the procedure known as " epidemiologic treatment " even when cultures (which may miss 20%, or more of such gonococcal infections) are negative. If chemotherapy is adequate, a link in a chain of infection may thus be broken. A patient who would refuse a diagnosis of venereal disease may willingly accept this precautionary measure, ...

Chronic Arsenic Intoxication in Asia: Current Perspectives

Chronic arsenic intoxication has been an issue of public health concern in some countries in Asia, such as Taiwan, Mainland China, Bangladesh, India, and Thailand. In Taiwan, an endemic peripheral vascular disease known as ‘blackfoot disease’ (BFD) located in a confined area along the southwestern coast of Taiwan attracted the attention of the government and the scientific professionals since m...
