1. A strain of cartilage cells, obtained from the pars cartilago sclerae of the eye of chick embryos, has been cultivated for more than 3 months in vitro. 2. The initial growth of the cartilage was possible only on the free surface of the coagulum. 3. The hyaline substance disappeared during cultivation in vitro. The succeeding stages of a transformation from small, lymphocyte-like cells into l...

The morphology, incidence and distribution of hyaline cells in ten cases each of pleomorphic adenoma, adenoid cystic carcinoma, adenocarcinoma and mucoepidermoid tumour were studied by conventional light microscopy. Results showed that the hyaline cells were identified in 60% of pleomorphic adenoma and in 20% of mucoepidermoid tumours, but were absent in adenoid cystic carcinoma and adenocarcin...

Juvenile hyaline fibromatosis (JHF) is a rare, progressive autosomal recessive disease that's characterized by papulonodular skin lesions, soft tissue masses, joint contractures, gingival hypertrophy and osteolytic bone lesions. We present here the case of a 2-yr-old boy with JHF along with a review of the relevant literature. This case demonstrates that JHF should be considered in the differen...

Juvenile byaline fibromatosis is a rare connective tissue disorder, characterized by skin tumours, gingival hypertrophy and flexion contractures of the acral joints. Other associations include stunted growth, osteolytic changes and muscle weakness. The mental development is normal. Juvenile hyaline fibromatosis probably has an autosomal recessive inheritance, characterized by increased synthesi...

The periodic appearance of a hyaline cap at the front of advancing pseudopodia is an almost universal accompaniment of movement in ameboid cells. The fluid of the hyaline cap cannot be a simple filtrate of the ground substance pressed through the "plasmagel sheet" as Mast (11, 12) believed, because the dry mass of this fluid is less than half that of the ground substance of the rest of the cell...

BACKGROUND Our case describe a rare recurrence case of Unicentric Castleman's disease (UCD) with hyaline vascular type 14 years after surgery. CASE PRESENTATION A 35-year-old Chinese female was admitted to hospital with one and half months history chest distress and chest pain. Patient reports a history of thoracic operation for mediastinal mass 14 years ago, and it was diagnosed UCD with hya...

Phospholipid analyses in tracheal, hypopharyngeal or gastric aspirates of premature infants have been performed in order to predict or to establish the diagnosis of hyaline membrane disease (HMD) [1, 2, 3, 4, 7]. The predictive value of solely measuring the lecithin/spingomyelin ratio (L/S) in these fluids is controversial. Few studies have included the detection of phosphatidylglycerol (PG), a...

A species not identifiable with any of the about 23 Myxobolus species recorded from the common carp so far, was detected in the gills of one- and two-summer-old specimens of the common carp ((Cyprinus carpio L.) cultured in pond farms in Hungary. The strictly tissue-specific plasmodia of the parasite were located, surrounded by hyaline cartilage cells, in the chondrous substance of the terminal...
