Abstract
HF exposure might produce adverse effects in industrial workers. A 3 mo. exposure of rats to HF at 10 mg/m3 8 h/day 5 days/wk resulted in increased blood serum concentrations of hydroxyproline and hydroxylysine and in enhanced urinary excretion of these amino acids and in changes of collagen fractions in the liver, lungs and skin. In all tissues studied (especially liver), soluble and insoluble collagen decreased. HF affected biosynthesis and maturation of collagen fibers.

Influence of methionine upon the concentration of malondialdehyde in the tissues and blood of rats exposed to sodium fluoride
The aim of the study has been to determine the influence upon the kidney, liver, and the blood prooxidative system, exercised by administration of methionine (Met), under conditions of oxidative stress induced by sodium fluoride (NaF).The experiment was carried out on Wistar FL rats (adult females) that, for 35 days,

Study on changes of clinical indicators and key proteins from fluoride exposure
Few studies have evaluated the biomarker changes of fluoride exposure. In order to explore early and sensitive indicators, animal experiment was designed. Ninety-six healthy SD rats (48 males and 48 females) weighing approximately 60 g were randomly divided into six groups of 16 animals each by gender average. Control animals

Effect of chronic exposure to sodium fluoride and 7,12- dimethylbenz[a]anthracene on some blood parameters and hepatic, renal, and cardiac histopathology in rats.
This study aimed to investigate the effects of both sodium fluoride (NaF) and 7,12-dimethylbenz[a]anthracene (DMBA), both separately and in combination, on some blood parameters and hepatic, renal, and cardiac histopathology in rats. Forty male Wistar albino rats, weighing 250–300 g, were randomly divided into one control and three experimental groups

Effect of inhaled waste anaesthetic gas on blood and liver parameters among hospital staff.
A significant health risk exists within a section of health workers that are exposed to anaesthetic gas and vapours, found in the atmosphere of treatment or operating rooms. These compounds are classified as waste anaesthetic gases (WAG). The present study aimed at identifying alterations in hepatic and haematological parameters occurring

Alteration of paraoxonase, arylesterase and lactonase activities in people around fluoride endemic area of Tamil Nadu, India.
BACKGROUND: Toxicity due to excess fluoride concentration in drinking water is of great concern in people who rely only on the ground water as their water source in many region of the world. METHODS: We collected samples and examined the toxicity of fluoride in a population residing at Salem, Dharmapuri and
