چکیده

[3H]thymidine uptake and colony counts are quantitative and inexpensive methods for studying Spiroplasma growth. Using these techniques, we demonstrated subtle effects on the growth of suckling mouse cataract agent of medium alterations, inoculum size, and freezing of cultures. In addition, suckling mouse cataract agent multiplied more actively under aerobic than under anaerobic conditions. These techniques have wide application for the study of Spiroplasma growth and will be useful for the development of a defined medium.

In vitro growth inhibition of human malignant melanoma cells by glucocorticoids.

The human malignant melanoma cell line, NEL, was found to contain glucocorticoid receptors. When the binding data were analyzed according to the method of Scatchard, results indicated a ligand binding capacity of 247 fmol/mg protein and a Kd of 1 X 10(-9) M. Additional studies show that the continuous incubation of NEL cells with triamcinolone acetonide (TA) for 72 hr results in a 30% inhibitio...

[Methyl-14C]-choline incorporation into nude mice bearing tumor xenografts-correlation with [methyl-3H]-thymidine: A pilot study

Background: Many in vitro studies suggested that choline incorporation into many types of tumors is related to cell proliferation. Whether in vivo choline incorporation is related also to cell proliferation or not was my question. Therefore, the aim of this pilot study was to investigate the relationship of in vivo [methyl- 14C]-choline incorporation and in vivo [methyl-3H]- thymidine incorpora...

Comparative Evaluation of Growth, Yield and Quality Characteristics of Various Gerbera (Gerbera jamesonii L.) Cultivars under Protected Condition

Ten gerbera cultivars (‘Labinel’, ‘Lilla’, ‘Alp’, ‘Alberino’, ‘Bonnie’, ‘Avemaria’, ‘Mammut’, ‘Lexus’, ‘‘Terramixa ’ & ‘Sarolta’) were evaluated for their growth, yield and quality characteristics under protected conditions during 2011. Among the cultivars studied, there were highly significant variations observed for growth, yield and quality parameters. Longest stalk length (60.3 cm) was exhi...

Basic fibroblast growth factor stimulates 3H-thymidine uptake in retinal venular and capillary endothelial cells in vivo.

Recent studies have found basic fibroblast growth factor (bFGF), an angiogenic peptide, in retina and have suggested that bFGF is responsible for retinal vascular proliferation. To test the hypothesis that bFGF stimulates 3H-thymidine uptake in retinal vascular cells in vivo, we injected bFGF (100 ng) into the vitreous cavity of six cats at 0 hr and again at 24 hr. Eight control eyes received b...

Evaluation of Specific Purified TCR Effect on the Immunoregulatory Potential of TGF-beta

Transforming growth factor beta (TGF-b) is a mediator released by nearly all cell types. It has suppression activity on the immune system, but exactly how this effect is carried out is not clear. Previous experiments showed that IgG interacts with or carriers active TGF-b, that could suppresses cytotoxic T-cell responses to an immunogenic tumor in mice. Since T cell receptor (TCR) has structura...
