acetic acid/atrophy

BACKGROUND Glutaraldehyde-related cytotoxicity and transanastomotic ingrowth inhibition prevent the spontaneous endothelialization of bioprosthetic heart valves. In order to evaluate the ability of improved biocompatibility to reduce tissue degeneration, conventionally fixed aortic root prostheses

Parkinson's disease is characterized not only by a progressive loss of dopaminergic neurons in the substantia nigra but also by a degeneration of locus coeruleus noradrenergic neurons. The present study addresses the question of whether a partial neurodegeneration of dopaminergic neurons using

In this work, α-lipoic acid and cyclosporine demonstrated significant protection against acetic acid-induced ulcerative colitis in rats. We proposed that α-lipoic acid and cyclosporine co-administration might modulate their individual effects. Induction of ulcerative colitis in rats was performed by

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

Albino rats six weeks (wk) of age underwent transection of the spinal cord at the level of the seventh thoracic vertebra. They were killed ten wk later by several schedules of formaldehyde-glutaraldehyde, formaldehyde and formaldehyde-ethanol-acetic acid perfusion-fixation. Layer Vb of the

The metabolic effects of intravenous administration of 200 mg/kg imidazole-4-acetic acid (IMA) on normoxic, hypoxemic and hypoxemic-oligemic rat brain were assessed by measurement of the cerebral contents of energy phosphates and selected glycolytic-citric acid cycle intermediates. In normoxic brain

Aqueous ammonia in concentrations of 0.02 or 0.1% was continuously administered to rats to study its effect on the gastric mucosa histologically and cell kinetically. Furthermore, acetic acid ulcer, which is a model of chronic gastric ulcer, was experimentally induced in the stomachs of rats to

A simple and rapid method for light and electron microscopic visualization of degenerating neuronal processes and axon terminals is described. Hundred-micrometer vibratome sections of perfusion-fixed rat brain were incubated briefly in a 5% silver nitrate solution in a conventional microwave oven.

We performed an observational study to investigate if plasma 5-hydroxyindole-3-acetic acid (5-HIAA), a derivative end product of serotonin (5-hydroxytryptamine), concentration could be a predictor for deterioration of urinary albumin excretion. The relationship between baseline plasma 5-HIAA

The significant predictors for the postoperative deterioration of separate renal function after minimally invasive stone surgery were investigated in the present prospective and observational study. A total of 117 consecutive patients who underwent retrograde intrarenal surgery or mini-percutaneous

Bovine fetal muscle cells were exposed to culture media containing 2 mg and 20 mg per liter of 2,4-dichlorophenoxy acetic acid (2,4-D) for varying intervals to determine the in vitro response of mammalian cells to this compound. The concentrations of 2,4-D used were comparable to those used in spray

OBJECTIVE To illustrate the cytologic features of hepatocellular carcinoma (HCC) after percutaneous acetic acid injection (PAI) and to correlate the cytologic findings with helical computed tomography (CT) findings. METHODS The study included 30 patients with 37 HCC who had undergone PAI. Baseline

The most important pathogen for table grapes is Botrytis cinerea which causes a rapid deterioration of fruit. Postharvest losses are controlled with SO2 fumigations carried out every 7 or 10 days, but the use of this gas is becoming more difficult to justify because of undesirable effects on the

One ml of 0.106%, 0.425% or 1.7% acetic acid (AA) solution, isotonic to physiological saline solution, was injected into the M. vastus lateralis of male Japanese white rabbits. Two, 7, 14 and 21 days after the injections, the rabbits were autopsied, and the removed muscles were observed

The reversibility of the effect of gossypol on testicular histology and fertility was studied in rats. Adult males of proven fertility were treated orally with gossypol acetic acid (15 mg/kg) for 9 or 16 weeks (groups 1 and 2, respectively). Another groups of animals (group 3) was given gossypol (15
