BACKGROUND: Monofunctional psoralens plus UVA radiation are not severely phototoxic and have less mutagenic activity than bifunctional psoralens plus UVA radiation. OBJECTIVE: The purpose of this study was to evaluate pigment producing effect using various concentrations(0.02%, 0.1%, 0.5%) of monofunctional psoralens such as angelicin, khellin and comparing it's effect with TMP in topical photochemotherapy. METHOD: Ninty three C57BL mice were painted with either angelicin, khellin or TMP solution in concentrations of 0.02%, 0.1% and 0.5% each and were UVA irradiated. Skin biopsies were performed at 1,3,5 weeks after UVA irradiation. The pigment producing effects were measured by the number, area and perimeter of the melanocytes after topical PUVA. RESULTS: The comparison of melanocyte numbers between different psoralens after five weeks of photochemotherapy showed a significant difference in decreasing order of TMP, khellin and angelicin. The area and perimeter of melanocytes were larger in the TMP group after five weeks photochemotherapy than the other group. However in the khellin and angelicin group, the area and perimeter of melanocytes were not increased by increasing the frequency of the UVA irradiation. CONCLUSION: The number, area and perimeter of melanocytes after topical PUVA increased in the TMP group compared to angelicin or khellin group. We expect the clinical application of angelicin and khellin in vitiligo is possible considering the result of the study of pigment producing effect with a higher concentration and higher dose of UVA.

Vitiligo is a relatively common depigmentary disorder occurring in approximately 1-2% of the general population. All races are affected. Both sexes are likely to be affected equally; the female prevalence in some studies can probably be attributed to cosmetic reasons. It can occur and spread at any stage of life and is often associated with a positive family history. Up to 30 percent of patients have reported vitiligo in another family member. The lesion is characterized by discrete, pale-white macules, few or several in number, which tend to enlarge centrifugally over time. It is not contagious, nor is it a serious health problem. However, it can be troublesome in brown and black people as well as in white persons who tan deeply (skin phototype IV), and often leads to social embarrassment and psychological turmoil.

Ehlers-Danlos syndrome is an inherited disorder of connective tissue in which joint hypermobility, hyperelasticity of skin, bleeding tendency, and scar formation are the most prominent features. It is a generalized disease with essentially universal involvement. A 3-year-old female child had velvety skin, skin hyperextensibility, joint hypermobility, subcutaneous mobile masses on the left shin, many scars on both knees, subcutaneous hematoma, and thick and very folded skin on both palms and soles, but no evidence of internal disorder. Cutaneous histopathologic findings were nonspecific without increase of dermal elastic fibers on Verhoeff stain. Diagnosis was confirmed by clinical and histopathological findings as Ehlers-DanIos syndrome.

The wandering spleen is a rare condition, in which the spleen is located in other than the left upper quadrant of the abdomen. The clinical manifestation is variable from asymptomatic to abdominal catastrophy due to torsion of the splenic pedicle. We experienced a case of torsion of wandering spleen in 8-year-old girl who admitted with fever, vomiting, abdominal pain, palpable left abdominal mass. She was diagnosed preoperatively with the aid of abdominal sonography and C.T. scanning. A splenectomy was performed and she made uneventful recovery. The case report illustrates some of the diagnostic and therapeutic considerations pertaining to wandering spleen with a brief review of related literature.
