Tow cases of congenital ectodermal defect in brothers aged 15 and 10 years were pesinted and the literature was reviewed. They had lack of sweating, sparseness of the hard hairs, absence of lanugo hairs, maldevelopment or defect of most of the teeth, etc. They seemed to be angidrotic type associated with a sex-linked reccessive inheritance in their family backgroud.

A fistulous comunication between kidney and colon after trauma is rare and usually causes severe damage to kidney necessitating nephrectomy. Intrarenal aneruysm after trauma is also rare and its accurate diagnosis is important. Authors have experienced a reno-colic fistula and intrarenal aneruysm occured in a same patient afterpenetrating renal injury.

Recent development of maxillofacial surgery has taken an interest in the regeneration of facial bone defects. For the reconstruction of facial bone defects, autogenous bone grafts have been widely used. However, there are some clinical problems : the morbidity of donor sites, resorption of autogenous bone graft and, the availability of the proper form and size. The purpose of this study is to find the effective solutions to above problems. The present study was designed to evaluate the roles and regenerating capacity of fibrin sealant. Fibrin sealant is a newly developed substance for hemostasis, tissue sealing and wound healing. I made the experimental study on the effects and roles of bibrin sealant in sutogenous bone graft procedure to minimize the above complications and problems. Twenty-five adult white rabbits were used as the experimental material. Three trephine defects were made by drilling on the parietal bone of each rabbit. Defect size was 8x8mm. First group consisted of the rabbits which had the artificial defect on the parietal bone as control. The defect in second group was sealed up with autogenous boon chip only. Last group comprised the rabbits autografted by mixing the bone chip with the fibrin sealant. The results were carefully examined grossly and microscopically from the 3rd day to the 28th day postoperatively. The following results were obtained ; 1. The mixture of fibrin sealant and bone chip was useful for regenerating the bone defects. Most of the defects were substituted by new bone. 2. In the case of the graft with bone chip only, most defects were also filled with new bone, but less than fibrin group. 3. In the control group, new bone was formed around the peripheral area only. A mixture of fibrin sealant and autogenous bone chip plays an effective role in forming new bone. find judging from the results of this experiment, it may be expected the much use of the fibrin sealant in maxillofacial orthopedic surgery.

CT was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any otherclassical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically andhistologically. The results were as follows; 1. Age distribution of the cases was 15 males and 16 females withpeak age of 6th decade in males and 4th decade in females. 2. Metastatic lesions were multiple in 18 cases andsingle in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Markededematous low densities with relatively small nodular high densities in precontrast scan and variable contrastenhancement of the nodular densities were the most frequent CT findings. 4. No specific characterstics accordingto the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.

BACKGROUND AND OBJECTIVES: Dimenhydrinate is known to act on the vestibular system, causing vestiular suppression. But the effects related with therapeutic dosage on eye tracking tests and vestibulo-ocular reflex (VOR) are not clear yet. We performed this study to evaluate the effects of dimenhyrinate on eye tracking tests and VOR. MATERIALS AND METHODS: Twenty five healthy subjects, comprising of 12 men and 13 women between the ages of 15 and 69 (mean age=39) participated in this study. The assessment included saccade test, smooth pursuit test, optokinetic nystagmus test for eye tracking test and sinusoidal harmonic acceleration test for VOR test. Each test was performed before, and 2 hours and 4 hours after the oral intake of dimenhydrinate (therapeutic dosage: 50 mg). The subjects were kept alert by performing a calculation task and communicating with the investigator during tests. RESULTS: Analysis of results showed that latency was prolonged after 2 hours but was returned to initiae value after 4 hours. Gain was not changed in the saccade test as well as in the smooth pursuit test. Mean slow phase eye velocity (SPEV) decreased after 4 hours in optokinetic nystagmus test. Gain and phase lead decreased only at 0.01 Hz in sinusoidal harmonic acceleration test. CONCLUSION: Dimenhydrinate had minimal effects on eye tracking tests and VOR when the patient's alertness was kept during test.
