The authors attempted to examine the distribution of S-100 protein in the human fetal skin. Immunohistochemical staining(ABC rnethod) using anti-S-100 antibodies was carried out on skin specimens taken from 11 human fetuses ranging from 9 weeks to 27 weeks of estimated gestational age. At 9 weeks of estimated gestational age, the embryonic epidermis consisted of three cell layers,' the basal layer, intermediate layer and periderm, all of them being stained for S-100 protein. But after 18 weeks, the basal layer changed to be negative. Granular and cornified layer's, beginning their development at 22 weeks, were not stained for S-100 protein. Hair germ of 12 week-fetuses was recognized unstained as a bulge of basal cells. In fully differentiated structural components of the hair follicle after 18 weeks, the outer root sheath only was stained for S-100 protein whereas the inner root sheath, hair matrix cells and sebaceous glands were unstained. Eccrine gland germs developed at 12 weeks of embryonic life as undulation of the basal layer and were not, stained. And at 22 weeks, the secretory portion of the eccrine glands were formed in the dermis and stained for S-100 protein. Our present study suggests that the expression of S-100 protein can undergo considerable changes during ernbryonic differentiation in the epidermis and epidermal appendages.

Reticulate acropigmentation of Kitamura (RAPK) is an autosomal dominant dermatosis comprising of reticulate slightly clepessed pigmentation of the extensor surfaces of the hands and feet with palmar pits. It has been suggested that this may be the same disease as Dawling Degos disease (DDD), an autosomal dorninant condition which is characterized by a reticulate pigmentation of flexures, comedo-like lesicns and pitted scars. We present a case of RAPK in a 49-year-old female who had reticulate, brownish, slightly depressed pigmentation on the extremities with t,he involvement of flexures, the predilection sites of DDD.

Previous observations have demonstrated that fibronectia (FN) is deposited high abundance in basal cell carcinoma (BCC) stroma. Since FN is a glycoprotein which promotes interaction between cells and extracellular matrix, it may been important component of slowly expansile carcinoma such as BCC. Furthermore, BCCs aggressiveness varies with it's histologic appearance. The authors investigated distribution of plasma FN (pFN) in 8 BCC cases with various histologic types (3 nodulocystic type, 2 infiltrative type, 2 keracotic type, 1 adenoid type) and 4 squamous cell carcinomas (SCC), which have a more aggrcisive biologic behavior than BCC using immunohistochemical staining. In normal skin, pFN was strongly positive at the clenzoepidermal junction and perivascular area with a linear pattern, and in the papillary dermis with a reticular pattern, and was weakly positive in the reticular dermis. In BCC, pFN was strongly positive in nodulocystic BCC, with the highest concentration along the periphery of the tumor island in a filamentous pattern, .hereas, it was moderately positive in adenoid, keratotic, infiltrative BCC stroma. In SCC, pFN was weakly positive around tumor the margins with a thin, coarse deposition These results show that with epidermal tumors, the degree of the pFN expression in stroma is propotional to their aggressiveness.

Staging of carcinoma of the urinary bladder is important for the choice of therapy and also has prognostic implications. Hitherto the staging has been based upon cystoscopy with bio psy, transurethral resection , and palpation with complementary radiographic examlnations such as cystography, urography, lymphangiography, ultrasound and angiography. However, with all these methods, the staging of bladder carcinomas still uncertain and inferior to CT. Authors analyzed CT staging of bladder cancers and compared with pathologic staging of laparotomy results. The results are as follows: 1. Overall accuracy of CT staging in bladder carcinoma was 72 percent. 2. Overstaging was 20 percent (5/25) and understaging was 8 percent (2/25). 3. All of CT stage B cancers were proven to be stage B, pathologlcally. 4. In 6 cases of CT stagec cancers,only one was correct,3 were overstaged and 2 were understaged. 5. In 7 cases of CT stage D cancers, 5 were correct and 2 were overstaged. 6. CT detected only 2 cases of pelvic Iymph node involvement in 4 of pathologically proven Iymphadenopathy.

Paralytic hand is the ultimate result of permsnent damage of the central nervous system, failure of the functional repair of peripheral nerve injuries and extensive muscular or tendinous defect resulting in the impairment of hand function. There are a lot of controversies in the side of treatment methods in the paralytic hand, and it is very difficult to formulate the most adequate surgical reconstruction for a given pstient. At Depsrtment of Orthopedic Surgery, Seoul National University Hospital, 66 cases oi paralytic hands in 62 patients have been treated surgically with tendon transfers for 7 years from Jan, 1980 to Dec, 1986. 49 case in 46 patients were followed up for more than one year, and surgical method and its results were anslysed. They consist of CNS lesion (17), peripheral nerve lesion(23) and musulotenidinous defect(9). The methods of surgical reconstruction were opponenesplasty(12), standard set extensor reconstruction(9), Green and Bsnks FCU transfer(11), intrinsic reconstruction(7), pronator rerouting(7), adductorplasty (5) and so on. The mean follow-up was 2.2 years, and in 38 cases good or excellent results were obtained.

Nine patients of clinically definite multiple sclerosis (MS) were examined by magnetic resonance imaging (MRI) at 1.0T. The MS plaques were seen in the brain and spinal cord in eight and three patients. respectively. The frequent sites of MS plaques were periventricular white matter, brain stem, and cervical cord. The shape of most brain MS plaques was round or finger-like configuration. The MS plaques showed high signal intensity on R2 weighted images and low or iso signal intensity on T1 weighted images in all nine cases. Contrast enhancement was seen in 4 cases. Mild brain atrophy was noted in 2 cases and mass effect in 1 case. The sites of cord MS plaques in three patients were C2-C4, C2-C5, and C4-C6 levels respectively. The cord MS plaques showed high signal intensity on T2 weighted image and contrast enhancement on Gd-DTPA enhanced T1 weighted images in all 3cases with mild cord expansion in 2 cases. In conclusion, MRI is a useful diagnostic tool in evaluationg the MS plaques involving central nervous system.
