Target cell-induced calcium signals in human natural killer leukemia cells as revealed by confocal fluorescence microscopy.

The target cell-induced calcium response in natural killer (NK) cells was examined using indo-1 (a ratiometric fluorochrome), a newly developed video-rate ultraviolet laser-scanning confocal microscope system, and a human NK leukemia cell line, YTN. Susceptible target cells (JY cells), but not unsusceptible target cells (K562 cells), increased the intracellular calcium concentration ([Ca]i) in almost all indo-1-loaded YTN cells with a lag time, although the kinetics of increase in [Ca]i differed in individual YTN cells. The increase in [Ca]i was completely blocked by 2 mM EGTA and partially (around 50%) blocked by 10 microM nicardipine, the extents of inhibition of calcium response correlating well with those of inhibition of cytotoxic activity. Thus, the calcium response in YTN cells observed in this study may constitute a critical step in the manifestation of cytotoxic activity.

The contour lines of the upper lip and a revised method of cleft lip repair.

Many techniques for cleft lip repair have been reported, but these techniques do not consider the contour lines of the upper lip and, in fact, destroy them. The upper lip has complicated contour lines including the vermilion free margin, vermilion border, upper lip horizontal groove (upper lip groove), philtrum (dimple and columns), nostril sills, and nasolabial grooves. Incision lines should be designed so that the postoperative scars do not cross these contour lines. We feel that our incision lines and postoperative scars provide better aesthetic results and diminish hypertrophic scar formation.

Operations for microforms of cleft lip.

Microform cleft lip is a mild expression of cleft lip and may be difficult to repair. Its severity may be defined by the degree of downward depression of the nostril rim, skin striae of the upper lip, notching of Cupid's bow, and deformity of the vermilion border. Variation in surgical repair is reported for each type of microform cleft lip.

Cleft lip-nose repair technique: sequential repair.

The results of repairing cleft lip by aesthetic plastic surgery are now excellent. However, the cleft lip-nose deformity is still very difficult to repair with the present techniques. A technique that can repair the cleft lip-nose deformity with good results is presented. The technique is divided into three parts: Part I consists of nasal repair of the primary cleft lip. Part II is nasal reconstruction as a secondary operation with or without lip repair. For example, nasal reconstruction may be secondary to repair of deformities of the sill, rim, limen nasi, septum, or nasal bones. Part III is an aesthetic nasal operation such as rhinoplasty, mentoplasty, or zygomaplasty.

Augmentation rhinoplasty.

Augmentation rhinoplasty using a silicone implant is the most popular operation in Japan, but is not without several complications such as exposure of the implant and its deviation. We obtained good results in preventing these complications by a fixation at the hollow which is made by chiseling the frontal bone and by fibrous tissue which grows through the small holes of the implant tail.
