A new epithelial cell line (TE-3) has been established from a metastatic lesion at the right chest wall which was originated from a well differentiated human squamous cell carcinoma of the esophagus. TE-3 has been subcultured more than 150 times for 3 years and 1 month. Cultured cells have grown as isolated colonies of epithelial cells. The average doubling time of the TE-3 cell line was 48 hr ...

This paper deals with an investigation of the effect of these reactions on bacteria. Not only the common staining behavior but also certain other similarities (Fischer et al., 1949; Fischer, 1951) between intact wool and gram negative bacteria, medium degraded wool and gram variable bacteria, as well as between highly degraded wool and gram positive bacteria suggested that reversal of gram stai...

The Congo red stain has undergone several modifications since it was first used by Bennhold in 1922 in order to increase the specificity for staining amyloid. Most of the laboratories in the United States use the method of Puchtler which uses alkaline Congo red solution. Some of the variables associated with the procedure were investigated by us. Our results showed the following: (1) amyloid sh...
