BACKGROUND: Transforming growth factor-beta(TGF-beta) has multiple regulatory effects on cells of the immune system, and it has been suggested that differentiation of lymphoid cells is influenced by low concentra tions of this cytokine. OBJECTIVES: The aim or this study was to investigate the role of TGF-beta in regulation of T cell growth and differentiation, and to compare this effect with that of other cell signals known to be important in T cell ontogeny. METHODS: We used the CTLL-2 cell line in the presence of IL-2. Surface phenotype expression was analysed to see whether these cells could be switched to the other subtype of cells. RESULT: Treatment of CTLL-2 cells with TGF-beta resulted in dose dependent growth inhibition and morphological changes. Curing routine passage, less than 5% of cells were CD8alpha positive, whereas 38% of cells expressed CD8alpha when treated with IL-2 plus TGF-beta. However, TPA plus calcium ionophore, IFN-gamma, or TNF-alpha caused no significant changes in the proportion of CD8 cells. CONCLUSION: Our results show that this experiment can be a useful model for investigating CD8 precursor potentials in populations of CD4-CD8-(double negative) cells, and such a model may offer a way to study the molecular regulation of CD8 gene expression.

Sonographic detection of ureteral jets entering the urinary bladder is a well-known procedure. Color Doppler ultrasound was used to image the ureteral jets in 28 patients with unilateral ureteral calculi proved by intravenous urography. Three major findings of ureteral jets were obtained in the affected ureter with a stone: less frequency (26 patients), weak reflection (20 patients), and lower grade in length (27 patients) that were significantly different from the unaffected side in the same patient. No significant differences were found between the ureteral jets and the degree of hydronephrosis or the location of a stone. In conclusion, these results suggest that ureteral jets should be checked routinely during the procedure of color Doppler ultrasonogram in patients with possible unilateral ureteral obstruction. Color Doppler examination of ureteral jets may be a important adjunct in routine pelvic ultrasonogram especially in patients who have absolute or relative contraindications of intravenous urography.

A computer progrem which performs obstetric calculation on Clipper Language using the datas from ultrasonography was developed from personal computer. It was designed for fast assessment of fetal development, prediction of gestagional age, and weight from ultrasonographic measurements which included biparietal diameter, femur length, gestational sac, occipito-frontal diameter, abdominal diameter, and etc. The Obstetricel-Ultrasound data-Base Managemant System was tested for its performance. The Obstetrical-Ultrasound Data-Base Management System was very useful in patient management with its convenient data filing, easy retrieval of previous report, prompt but accurate estimation of fetal growth and skeletal anomaly and production of equation and growth curve for pregnant women.

Meigs' syndrome is defined as a hydrothorax with ascites and a pelvic tumor, both of which resolve on removal of the tumor. Pseudo-Meigs' syndrome is a variant not possessing the original tumor cell types described by Meigs. Both these syndromes should be considered in otherwise healthy women who present with either new or recurrent hydrothorax and ascites. Pseudo-Meigs' syndrome occurs with the clinical triad of (1)ascites, (2)pleural effusion and (3)Brenner tumors, struma ovarii, benign thecomas, extreme ovarian edema, uterine leiomyomas or other benign pelvic tumors. A case of Pseudo-Meigs' syndrome associated with Brenner tumor is presented with a brief review of literatures.
