Adhesive forces between the retina and the retinal pigment epithelium, which is mainta ined by active mechanisms unique for living animals, deteriorates rapidly after death and leads to spontaneous retinal detachment. Change of retinal adhesiveness in rabbits after death was investigated using a new method. Retinal detachment was induced by applying various levels of aspiration power from 0 to 1OO mmHg to the vitreous cavity using a vitrectomy instrument immediately after the rabbit was killed without enucleation. And the time required for creating the retinal detachment was measured. Retinal adhesiveness deteriorated and spontaneous retinal detachment occurred 28 minutes and 35 seconds after death confirming the active adhesion between the retina and the retinal pigment epithelium before death Increase of aspiration power led to shortening of time required for creating retinal detachment. From aspiration powers of 0 to 100 mmHg, the common logarithm of time required for retinal detachment was inversely proportional to the aspiration power [IogY = 1.45215 - 0.01113X, (R2=0.99041), X: aspiration power (mmHg), Y: time required for creating retinal detachment (minutes)]. Thus, presumed time of retinal detachment could be estimated between the aspiration powers of 0 to 100 mmHg.

The veins of the lower limb are subdivided into deep veins, superficial veins, and comminucating veins. The deep veins accompany the arteries, while the superficial veins course under the superficial fascia just beneath the skin and they have great, small saphenous veins, and their tributaries. The superficial and deep veins are connected by the commincating veins, which are usually located along the intermuscular septum. There are many reports about the venous system of the lower limb in foreign countries but a few in Korea. It is considerably valuable in the vascular surgery of the lower limb and the surgical management of the varicose veins. This study deals with the Korean cadavers, the authors observed the location of the saphenofemoral junction, medial and lateral femoral circumflex veins, and deep femoral veins, and the termination modes between the superficial veins and great saphenous veins and the femoral circumflex veins to the deep femoral veins or femoral veins. The following results were: 1. Any noticeable anomalies of the femoral vein proper were not present. 2. The saphenofemoral junctions were located at 3.78±0.91cm below the inguinal ligaments, 2.22±1.18cm below the pubic tubercles, 3.99±0.99cm lateral to the pubic tubercles. 3. The termination modes of superficial veins to the great saphenous veins around the fossa ovalis were classified into 3 types, Type I: Superficial epigastric vein, superficial iliac circumflex vein, external pudendal vein emptied into the upper end of the great saphenous vein(45.1%). Type II: One or more veins among above mentioned 3 veins emptied into the lateral accessory saphenous vein (48.8%). Type III: One or more veins among above mentioned 3 veins emptied into the medial accessory saphenous vein(4.9%). One cadaver(1.2%) was not belonged to the above classification, in which above mentioned 3 veins were emptied directly into the femoral vein. 4. The termination level of deep femoral veins into the femoral veins was 8.68±1.92cm below the inguinal ligaments, 6.60±1.98cm below the pubic tubercles, 5.28±51.46cm lateral to the pubic tubercles. 5. The termination level of medial femoral circumflex veins into the femoral veins or deep femoral veins was 5.10±1.73cm below the inguinal ligaments, 3.65±1.92cm below the pubic tubercles, 4.62±1.41cm lateral to the pubic tubercles, and the termination level of the lateral femoral circumflex veins into the femoral veins or deep femoral veins was 7.00±1.48cm below the inguinal ligaments, 5. 05±1. 67 cm below the pubic tubercles, 5. 41±1.21 cm, lateral to the pubic tubercles. 6. The termination modes of femoral circumflex veins were classified into 4 types in male cadavers, Type A: Medial and lateral femoral circumflex veins emptied into the femoral vein. Type B: Medial femoral circumflex vein emptied into the femoral vein and lateral femoralcircumflex vein emptied into the deep femoral vein. Type C: Medial femoral circumflex vein emptied into the deep femoral vein and lateral femoral circumflex vein emptied into the femoral vein. Type D: Medial and lateral femoral circumflex veins emptied into the deep femoral vein. In the right sides, type A was 94.1% and type C was 5.9% while in the left sides, type A was 79.4%, type B was 5.9% and type C was 14.7%. 7. The collateral circulations were identified in 67 observations (81.7%) and venous circles were identified in 46 observations (56.1%).

The purpose of this study was to find educational needs of toddler's mother in child-caring experience. The subject of the study was toddler's mother who visited one health care center in J city for immunization and had a child or children between twelve and thirty six months old. The subjects were 37 mothers. The instrument used for this study was a semi-structured questionnaire developed by researcher and based on Objective Content Test of Garretson(1967). The Collected data were analized by two researchers using the method of content Analysis. The results of this study are summarized as follows ; 1) Of the large categories, the need of the highest frequency was 'prevention and management of disease and injury', that of the lowest 'growth and development'. 2) In 'physical care' category, 'care of sleeping' was the highest. In 'nutrition and eating-habitual management' category, 'weaning management' was the highest. In 'prevention and management of disease and injury' category, 'disease management' was the highest. In 'discipline and teaching' category, 'discipline' was the highest. 3) In comparison with preceding references, the educational needs of child-caring which had not been shown in preceding references but had been shown in this study were hair-caring, kind of weaning diet, method of cure and nursing, management of deformity, and so on. In conclusion, educational needs of toddler's mother in child-caring experience were matter-of-fact and inclusive. Needs in management of special situation such as disease were higher than usual parenting procedure or method. In addition, there were higher needs in questions happened through child-caring experience or confirmation of procedures practicing now. Then, it is suggested that parent education program should be developed on the basis of educational needs found in this study to be more effective in preparing mothers's child-caring.

The bone formation of periarticular connective tissue after head injury and total hip arthroplasty is included in the category of heterotopic ossification. Induction of a new bone formation in the soft tissue is related to various materials such as bone morphogenic protein. The alkaline phosphatase and acid phosphatase act as important factors in the formation and absorption of the bone. The acid phospatase has the important function of acting as the control with specific activity of phosphatase in vivo. Cholecalciferol induces absorption of the calcium in the alimentary tract and bone resorption and increment of bone calcification, whereas disodium etidronate inhibits the deposition and dissolution of calcium salt and formation of heterotopic bone. This paper reports on the relationship of alkaline phosphatase and various phosphoaminoacid phosphatase which affect the cellular differentiation and remodelling in the heterotopic ossification, with the effect of cholecalciferol and disodium etidronate on the heterotopic bone induction in rats. The following results were obtained: 1. The contents of the calcium in the implanted bone matrix increased markedly from two to five weeks. There was no changes in the calcium content by cholecalciferol or in the administration of small doses of disodium etidronate (5mg/kg). However, in the administration of large dose of disodium etidronate (25mg/kg), calcium mobilization was totally suppressed for the whole period of the experiment. 2. The protein content in the implanted bone matrix did not much change for the whole period of the experiment and the administratinn of cholecalciferol or disodium etidronate also had no effect on the protein content. 3. The activities of alkaline phosphatase in the implanted bone matrix peaked at two weeks in control or cholecalciferol group, whereas disodium etidronate admninstration caused the highest activity in the third week. 4. The activity of acid phosphatase in the implanted bone matrix increased in first and third weeks by cholecalciferol treatment. Disoidum etidronate inhibited the activity of the acid phosphatase in the first, fourth & sixth weeks of implantation. 5. The activity of phosphoserine phosphatase increased due to cholecalciferol treatment, but was significantly inhibited by disodium etidronate (25mg/kg) treatment. 6. The activity of phosphothreonine phosphatase in the implanted bone matrix slightly increased due to cholecalciferol treatment, whereas the activity decreased significantly for the whole period of the experiment by disodium etidronate (25mg/kg) treatment. 7. The activity of phosphotyrosine phosphatase in the implanted bone matrix was not change much for the whole period of the experiment and the administration of cholecalciferol or disodium etidronate had no effect on the activity of phosphotyrosine phosphatase. In conclusion, the disodium etidronate (25mg/kg) almost completely inhibited the molilization of calcium and the activities of acid phosphatase, phosphoserine and phosphothreonine phosphatases. Therefore, it can be suggested that the above phosphatases are closely related to the action mechanism of disodium etidronate.

Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

Melanoma is relatvely uncommon malignant tumor arising in the skin from epidermal melanocytes, from the junctional component of a cellular nevus or, rarely within a blue nevus and frequently metastasizes to regional lymph nodes first, followed by hematogenous spread to lungs, liver, gastrointestinal tract, pancreas, adrenal, heart and brain. All melanoma patients are carefully evaluated according to several parameters. A complete history and physical examination are carried out, with particular attention being devoted to other pigmented tumors that the patient may have. The patient should be further evaluated to determine the presence or absence of metastases by chest X-ray examination, metastatic series or bone scan, liver function studies, liver scan, EKG, etc. Special factors such as age, sex, and race, as well as site, size, and growth rate of lesions are also evaluated. We had a case of 59 year-old male patient with disseminated malignant melanoma. Upon his first visit, we did not find any abnormality in his physical examination and routine laboratory findings except skin tumors on left heel and left leg.
