The author evaluated the optimal concentration of 3 compositions of TIC medium which has used as the melanacytes culture medium. The concentrations of placental extract and bovine pituitary extract, which have the ability to promote proliferation of melanocytes, were evaluated also. Modified TIC medium with above 5 components of evaluated concentration was very effective in melanocytes culture. The results were as follows : l. 12-0-tetradecanoyl-phorbol-13-acetate (TPA) showed effective melanocytes proliferating activity at the concentration of 30ngml (p(0.05) 2. Isobutylmet:hyl xanthine (IBMX) showed effective melanocytes proliferating activity at the concentration of 0.3mM (p(0.05) 3. Cholera toxin (CT) showed effective melanocytes proliferating activity at the concentration of )OnM (p(0.05) 4. Two percentages of placental extract in culture medium showed effective melanocytes proliferating activity. S. Two percentages of bovine pituitary extract in culture medium showed effective melanocytes proliferating activity. 6. Placental extract and isobutylmethyl xanthine proved to have high melanocytes proliferating activity. 7. Melanocytes proliferated rapidly on modified TIC medium (Proliferation doubling time . about 43 hours) 8. The peak time of melanocytes proliferation (7.2 X 10/cm) was observed on the seventh day of culture, From this data, this culture system can be recommended as a new melanocytes culture.

Washboard nail is a dystrophy that presents as a series of ridges that extends across the nail. It is often accompanied by a central depression that extends from the cuticle to the free edge. Washboard nail is often a result of frequently repeated trauma, but sometimes predisposing factors cannot be found. When habitual tic is the cause of the lesions, restraining the habit is the most important treatment. Here, we report a case of a 6-year-old male with washboard nails on both thumbnails and was treated with topical 0.1% tacrolimus ointment. Significant improvement was observed after 4 months of application. This case suggests that topical tacrolimus can be considered as a primary therapy in the treatment of washboard nails in the absence of trauma.

Chemical destruction of Gasserian ganglion by either alcohol or phenol has remained a popular form of treatment for tic pain. However, control of the lesion size is inaccurate and various complications have often resulted. With advent of radiofrequency generator, percutaneous coagulation of the Gasserian ganglion is now possible, and the need for open surgery or chemical destruction have been drastically reduced. We treated 3 cases of trigeminal neuralgia with the radiofrequency current. Modified Hartel's anterior appaorch for the injection of the Gasserian ganglion is utilized and the radiofrequency lesions were made in the second branches of the trigeminal nerve selectively preserving the touch sensation in our patients. We reviewed the literature and described the technical procedures.

BACKGROUND: The biosynthesis of melanin is initiated by the enzymatic oxidation of L-tyrosine to L-dopa by tyrosinase. Some precursors of melanin are cytotoxic, and melanoma cells are killed as a risk of exposare to excess tyrosine or dopa in the culture medium. However, there have been few observations of the effects of L-tyrosine on cultured normal human melanocyte. OBJECTIVE: In order to investigate whether exogenous tyrosine induces cytotoxicity in cultured normal human melanocytes as in melanoma cells, we examined the effects of L-tyrosine on proliferation and melanization in normal human melanocytes. METHODS: A melanocyte culture was produced with a modified TIC medium. L-tyrosine was added to the culture medium, 100, 200, 400, and 800uM. After 2 days of incubation, the proliferation was measured by methylthiazol tetrazolium(MTT) assay and sulforhodamine B(SRB) assay. The melanin contenis were also measured by the modified Whittaker's method. RESULTS: On MTT assay, the proliferation of melanocytes had been stirnulated significantly (p< 0.05) in all L-tyrosine added groups. On SRB assay, the proliferation of melanocytes had heen stimulated significantly (p<005) in 200, 400, 800uM of L-tyrosine added groups. The melanin contents had increased in all L-tyrosine added groups, and had increased significantly (p<0.05) in 400uM of L-tyrosine added group. CONCLUSION: L-tyrosine is not toxic to normal melanocytes, It stimulates the proliferation and melnization of cultured normal human melanocytes.

We review the effect of methylphenidate, focusing on Osmotic-controlled Release Oral delivery System (OROS) methylphenidate, on cardiovascular system, appetite and growth, sleep, tic, epilepsy, psychiatric and rare adverse events. Although OROS methylphenidate has side effects including increased heart rate or blood pressure, decreased appetite, delayed sleep onset, emergence or aggravation of tics, withdrawal or changes in mood, these effects appeared to be minimal in impact or difficult to distinguish from risk to untreated population and tended to be improved by dose adjustment or drug discontinuation. However, in subjects with underlying cardiac problems, uncontrolled epilepsy, previous psychotic episode, clinicians should pay attention and balance the risk and benefit.
