BACKGROUND Little is known about the relationship between splenic arteriolar hyaline and cause of death. The purpose of this retrospective study was to evaluate the clinicopathological significance of splenic arteriolar hyaline in autopsy cases and estimate the applicability of hyaline for diagnosing the cause and rapidity of death. METHODS Archival data and histological slides from 82 cases ...

INTRODUCTION It is common for leiomyoma to undergo various secondary changes like hyaline degeneration, cystic change, myxoid degeneration, infection, necrosis, calcification, red degeneration and very rarely ossification. They are said to result from inadequate blood supply resulting in replacement of muscle fibres by hyaline material, collagen, calcium, mucopolysaccharides or a combination of...

Light and scanning electron microscopic (SEM) examinations were used to study the hyaline zone and associated root resorption after orthodontic treatment of the upper first molars of rats. The orthodontic treatment consisted of a fixed buccal expansion appliance with an initial force of 250 mN. The animals were divided into nine experimental groups with orthodontic treatment and one control gro...

In former investigations (1) we observed the deposition of a hyaline substance in the connective tissue of the uterine mucosa and muscularis of mice injected with large doses of estrogen for a period of two months or longer. This hyaline material acted in certain respects like a foreign body, in some instances causing the formation of epithelioid and small giant cells which helped in its absorp...

The pathogenesis of hyaline membrane disease is not only unsolved but also highly controversial and 'there exist almost as many theories about it as there have been serious observers' (Stowens, 1959). Among these theories some are based on the assumption that circulatory disturbances play a role in the development of the hyaline membranes. Transudation of constituents of blood plasma has been c...

PURPOSE To determine the nature of hyaline membranes in different manifestations of diffuse alveolar damage, [pulmonary and extrapulmonary acute respiratory distress syndrome], and idiopathic [acute interstitial pneumonia]. MATERIALS AND METHODS Pulmonary specimens were obtained from 17 patients with acute respiratory distress syndrome and 9 patients with acute interstitial pneumonia. They we...

Infantile systemic hyalinosis is a rare, progressive, fatal condition with a presumably autosomal recessive mode of inheritance. It is characterized by widespread deposition of hyaline material in many tissues. We present a three-month-old girl with hypoproteinemia, growth retardation, and generalized stiff and edematous skin, who was diagnosed as protein-losing enteropathy. A final diagnosis o...

We have generated and characterized a monoclonal antibody (McA Tg-HYL) that recognizes sea urchin hyalin as evidenced by immunofluorescence staining of the hyaline layer (HL) and immunoblot staining of the hyalin protein band. On immunoblots of HL extracts only the hyalin protein reacted with McA Tg-HYL. Immunoprecipitates of radioactive proteins from embryos incubated with [35S]methionine yiel...

Neuronal Lewy body-like hyaline inclusions (LBHI) and astrocytic hyaline inclusions (Ast-HI) are morphological hallmarks of certain familial amyotrophic lateral sclerosis (FALS) patients with superoxide dismutase-1 (SOD1) gene mutations, and transgenic mice expressing the human SOD1 gene mutation. The ultrastructure of inclusions in both diseases is identical: the essential common constituents ...
