formaldehyde/atrophy

General toxicity and genetic materials damage of formaldehyde on germ cells in different stages was studied. In order to discover the toxicity mechanism of formaldehyde on germ cells and the biomarkers of effect after the presence of damage in germ cells and the estimation index, the relationships

Formaldehyde (FA), a ubiquitous environmental pollutant, is extensively used in hospitals, laboratories and many industrial settings. Previous studies have showed that short-term, high-dose FA exposure is toxic to male reproduction of mammals. In this paper, we evaluated the male reproductive

We aimed to investigate of protective role of proanthocyanidin (PA) and vitamin E (vit E) against to toxic effect of formaldehyde (FA). Twenty-eight Wistar albino rats were divided into four groups: control group, rats treated with FA intraperitoneal (i.p.) (10 mg/kg), FA + vit E intragastric (i.g.)

BACKGROUND Formaldehyde (FA), one of the simplest organic molecules, is a flammable, pungent, irritating and colorless gas. This study aimed to investigate the effects of various concentrations of FA vapor on sperm parameters and testicular tissue. METHODS In this experimental study, we randomly

The part played by basement membrane in the guidance of peripheral nerve growth in vivo has been assessed by examining the capacity of degenerating mouse muscle to support the regeneration of the cut sciatic and saphenous nerves. Ethanol and formaldehyde-fixed gluteus maximus muscles were implanted

The effect of a single injection of d,1-p-chloro-N-methylamphetamine (PCMA) on 5-hydroxytryptamine (5-HT)- containing neurons in rat brain was investigated using fluorescence histochemical, electron microscopic and biochemical methods. PCMA caused in a dose-dependent manner (from 4.3 mg/kg), an

After reconsidering the physicochemical mechanisms involved in the so-called degeneration methods for the demonstration of axons and nerve terminals, the method of Eager was fundamentally modified in order to stabilize the staining process. This resulted in a simple and reliable method which stains

The present study examines long-term effects of occupational exposure to formaldehyde fumes on lung function. Forced spirometry and diffusing lung capacity were measured in 16 health-service professionals (8 medical doctors and 8 laboratory technicians) working at the pathoanatomic laboratory for at

Formaldehyde is a nasal carcinogen in rats but it remains to be determined what cancer risk this chemical poses in humans. Molecular dosimetry studies of formaldehyde and cellular proliferative responses to formaldehyde-induced cytotoxicity have been studied in the rodent and are important

Ethoxylated alcohols are non-ionic surfactants. The majority are used in household cleaners, laundry products, toiletries and in industrial and institutional cleaners. In previous studies, an ethoxylated non-ionic surfactant of technical quality showed allergenic activity in guinea pig experiments.

OBJECTIVE To determine analgesic effects of intraneural injection of ethyl alcohol or formaldehyde in the palmar digital nerves of horses. METHODS 6 horses. METHODS Ethyl alcohol was injected in the medial palmar digital nerve of 1 forelimb, and formaldehyde was injected in the contralateral nerve.

To study the significance of damage to the nasal mucosa for the induction of nasal tumours by formaldehyde in rats, a long-term inhalation study was conducted in which male rats with severely damaged or undamaged nose were exposed 6 h/day for 5 days/week to 0, 0.1, 1.0 or 10 ppm formaldehyde vapour

The effects of formaldehyde on biofilm morphology and biomass activity were investigated in an ultracompact biofilm reactor (UCBR) for carbonaceous wastewater treatment. The wastewater contained a fixed amount of glucose (with a chemical oxygen demand concentration of 600 mg/L) and an increasing
