[Imaged thoracoscopic surgery for bronchogenic cyst in posterior mediastinum--a case report].

A 44-year-old female with bronchogenic cyst in the posterior mediastinum was treated successfully by employing imaged thoracoscopic surgical methods in the same way as laparoscopic cholecystectomy. The patient was placed in the left lateral decubitus position. A first 3.

[Two resected cases of malignant fibrous histiocytoma originated from the thoracic soft tissues].

Two resected cases, a 56-year-old man and a 49-year-old man, of malignant fibrous histiocytoma originated from the soft tissues of chest wall were reported. In both cases, MFH was histologically diagnosed prior to our radical operation. One patient received an incisional biopsy and the other was a recurrent case after excisional resection in other hospital.

[A case report of solitary bone cyst of rib detected from pathological fracture].

A case of solitary bone cyst of rib was reported. The patient was 28-year-old man who was admitted to our hospital complaining of chest pain caused by pathological fracture of the left 10th rib. Chest x-ray film revealed a solitary cystic lesion of the 10th rib.

VMA mass screening program of neuroblastoma for infants in Nagoya City, Japan.

In Nagoya City, Japan, VMA mass screening for detection of neuroblastoma has been performed since 1977. Filter paper strips wetted with urine are mailed to a central laboratory. Positive tests are followed up by more definitive testing.

Inhibition by neuroblastoma growth inhibitory factor of ascites-type neuroblastoma cell growth in coculture with normal glioblasts.

A new ascites type neuroblastoma clone (NAs-1), which is characteristic both in anchorage-independent growth and catecholaminergic functions, attached on the monolayer culture of glioblasts and was subjected to morphological differentiation including the extrusion of neuronal processes. Other conventional neuroblastoma cells (Neuro2a, NS-20Y, and N1E-115) as well as NAs-1 in cocultured with normal glioblasts underwent a decrease in cell growth rates and DNA synthesis under the effect of the neuroblastoma growth inhibitory factor (NGIF) produced by glioblasts. After their NGIF production had been reduced by u.
