Zinc is known to be important nutrient for normal growth of animals, plants and men. Especially, zinc is essential for the proper healing of wounds. It is generally accepted that zinc deficieney interferes in someway with wound healing and this can be corrected or prevented by the administration of zinc containing compounds. Giving zinc to a patient who is not zinc deficient will not improve wound healing and may be detrimental if excessive amounts of zinc are given. In our study, the rate of healing of open wound on the dorsolateral aspects of normal rats has been observed after zinc ointment being given topically and following results were obtained. 1. Macroscopically, wound contraction rate was reduced significantly at postop. 15days, about 13% compared with that of control group. 2. Biochemically, alkaline phosphatase activity, which was a major part of fibroblast activity, was markedly increased in postop. 6 days and then abruptedly decreased in control group, but in zinc treatment group, slowly decreased and in postop. 15 days the activity was htgher than control group. 3. Histologically, phagocytosis was depressed or inhibited at postop. 3 & 6 days quantatively comparing with that of control groups. 4. As an above results, local application of zinc ointment in treatment of keloid and hypertrophic scars is suggested to be effective, so further clinical investigatons are needed.

There has been a dramatic decrease in the incidence of tuberculosis in Korea, as a result of changes in general public health and hygiene, with lessening of crowded living condition and improved nutritional status of general population. With marked decrease in its general incidence of tuberculosis, head and neck involvement gas become quite rare. As a consequence, clinicians are not considered the disease as a primary part of differential diagnosis, so that there are undoubtedly patients in whome proper diagnosis and therapy are delayed or the the diagnosis is missed entirely? This is particulary unfortunate since tuberculosis has become an completely treatable disease. In this patient, any evidence of pulmonary tuberculosis in chest radiography was not recognized and same results were results were obtained from intraoral cavity and regional lymphnode. Here we report a case of primary tuberculosis of parotid gland in female patient. We confirmed the diagnosis of tuberculosis from the results through lesional biopsy at operation field and histopathologic examination.

Immobilization of unilateral(right) lambdoid suture was produced in 9-day-old rabbits to determine its effect on subsequent craniofacial growth. The suture was immobilized by the topical application of methyl-2-cyanoacrylate adhesive, subsequent growth effects on the cranial vault, cranial base and facial skeleton were assessed by serial radiographic cephalometry. The statistically significant result(p < 0.05) were: 1. The growth of immobilized lambdoid suture was decreased accompanying compensatory growth at coronal suture bilaterally. 2. The length of anterior and posterior cranial base was increased. 3. Anterior midfacial height was increased. 4. Lower midfacial angle(angular relationship of cranial base to lower midface) was decreased. With the view of above findings, it is clear that restricted growth was seen at unilateral lambdoid suture accompanying compensatory growth at coronal suture and resulted in altered cranial base and facial growth.

The tongue is located inside the oral cavity at rest, and the structural interrelations between the tongue and the oral cavity is essentially important for normal tongue function. Macroglossia is clinically diagnosed whenever the tongue does not fit the oral cavity, thus patients complain of noisy breathing, drooling, speech and swallowing dysfunction, malocclusion, and social ridicule. Partial glossectomy for macroglossia volume has been assumed to be difficult. In this study, we attempted to measure the tongue volume with the plaster tongue model in a 7-year-old macroglossia patient. This method is reliable and simple for measuring the tongue volume in macroglossia.

The suture was immobilized by the topical application of methyl-2-cyanoacrylate adhesive, subsequent growth effects on the cranial vault, cranial base and facial skeleton were assessed by serial radiographic cephalometry. The results statistically significant(P<0.05) are: 1. Reduction in growth at lambdoid suture accompanying compensatory growth at coronal suture. 2. Increased length of anterior and posterior cranial base. 3. Increased anterior midfacial height. 4. Reduction of lower midfacial angle(Angular relatioship of cranial base to lower midface).

Human clonorchiasis is one of the most common trmatode diseases and of very important pubic health problems in Korea. In the present study, the changing patterns of specific IgG antibody was demonstrated by the enzyme-linked immunosorbent assay(ELISA) in the sera rabbits infected with clonorchis sinensis. The O.D> (optical density) values of the ELISA in the sera were merwured according to intensity and course of infections and tendency of decrease after chemotherapy. The ELISA was performed with veronal buffered saline antigen of clonorchis, peroxidase conjugated antirabbit IgG and ortho- phenylendiamine as a substrate by micro method. In the 3 groups of rabbits infected with 50(A group), 500(B group) or 100×5(C group) metacercariae, the sera were prepared biweekly up to 18th week before chemotherapy, and biweekly up to 24th week after chemotherapy. The results were as follows: 1. O.D. values increased gradually with lapse of time before treatment. The O.D. values indicated firstly 1.000 or more in 8 weeks after infection in A group and 4 weeks after infection in both B and C groups. The O.D. values reached plateau at 10 weeks after infection in A group and 8 weeks after infection in both B and C groups. Regression equations between the O.D. values of the ELISA and period(week) after infection among 2 groups were as fllows, y=0.09x+0.319 in A group y=0.08x+ 0.826 in B group and y=0.08x+0.807 in C group. 2. The O.D. values in A group which had been treated decreased gradually and became preinfection level at 24 weeks after chemotherapy. On the contrary the O.D. values in A group which has not been treated showde plateau. The O.D. values in both B and C groups which had been cured decreased gradually and became preinfection level at 24 weeks after chemotherapy.

Traditional bone donor sources include the rib, ilium and tibia all share some disadvantages such as postoperative pain, limitation of exercise etc. So an alternate donor site with minimal morbidity is desirable. The potential of the calvarium as a bone donor site for craniofacial reconstructive surgery has been recently realized and its many davantages are now recognized. Thirty one patients received autogenous calvarial bone grafts due to various etiology and follow up at least 1 month to 18 months at Department of Plastic and Reconstructive Surgery at Kyung Hee University hospital from May 1986 to July 1988. The results are as follows ; Calvarial bone as a bone donor site has following advantages 1. A visible scar at the donor site is avoided 2. Appropriate curvature is obtained when the donor site is properly selected. 3. Pain and functional inability are absent 4. Easy to molding for the adjustment to the recipient site 5. Grossly there is no secondary deformity due to bone resorption In the authors' experience, calvarial bone grafting is useful technique in restoring craniofacial surface defects.
