A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.

Horizontal Mattress Suture Technique on Microvascular Anastomosis of rat (body weight: 200-250 gm) femoral artery was evaluated. The present study was conducted to compare the horizontal mattress suture with simple interrupted suture on the suture time, patency rate of the sutured vessels, and the histological changes of surgical site of the vessel wall during wound healing period. The mean suture time of the vessel wall with horizontal mattress suture technique was 15 min 49 sec ± 2.14, which is significantly shorter than that of simple interrupted suture technique. The patency rate of the sutured vessel in both groups was statistically not different each other till post-operative 3rd day but patency rate of horizontal mattress suture was higher than that of simple interrupted suture at post-operative 3rd week. The histological findings such as intimal noss, medial degeneration and intimal regeneration were similar in both groups.

In clinical microsurgery, limitation of space often prohibits rotation of a double clamp in an end-to-end anastomosis, or shortage of length of the secondary vessel in an end-to-side anastomosis does not allow visualization of the back wall. In these situation, back wall repair is extremely difficult. To overcome this problem, we use continuous suture technique without rotation of double clamp for end-to-end and end-to-side anastomosis of the 40 rat femoral arteries. After continuous sutures for micro-arterial anastomosis, the following results were obtained: Continuous sutures are useful in anastomosis where there is unavoidable limited access to the posterior wall and for some of the larger vessels now being anastomosed in free flap and other reconstructive surgery.

Keloids are abnormally healed skin wounds that develop in the subpapillary layer of the dermis. They are a lesion with wide, raised and deep scars. They exceed the original dimensions of the wound and grow mounds upon mounds of collagen in a pseudotumor fashion. Their treatment may take several forms such as surgery, intralesional injection of steroid, compression, superficial irradiation, and combination therapy. However, absolute method is nothing until now. Recently, the cryosurgery shows relatively good effect in treatment, so we tried the clinical experience with cryosurgery in the treatment of keloids. Material and methods: During the past 2 years, we treated 20 individuals of the keloids with severe itching and pain. The age ranged from 5 to 45 years old. Only 6 cases were biopsied before and after cryotherapy. The cryosurgery set we used was Toitu model CR 201 N₂O gas (tip temperature in 80℃) and was applied directly on the lesion about 4 to 5 minutes with slight compression. After cryosurgery in keloids, the following results were obtained: 1. It is both quick and easy method. 2. It is causes little or no pain and no loss of blood. 3. Integumentary normalization is rapid. The new scar tissue is smaller, and more elastic and soft. 4. The pain, itching and paresthesia commonly associated with keloid is usually disappeared. 5. Other treatment can be used after cryosurgery. 6. Histologic picture after cryosurgery is similar with the result of steroid injection. 7. The mechanism of the cryosurgery in keloids is the result of the direct tissue destroying action and cryoimmunologic reaction.

In this animal study, comedones were induced by topical application of oleic acid onto the rabbit ear canal and the histopathologic and ultrastructural changes in response to topical application of HO and hexane extracts of red ginseng, and saponin were measured. No microscopical difference was observed between treatment groups. Nucle ir remnants were observed in the horny cell layer as well as the thinning of the granular cell layer. Scattered and decreased keratohyaline granules were also noted. Six weeks after initiation of treatment, we observed the thinning of epidermis and veappearance of granular cell layer with normal keratohyaline granules. After treatment, scanning electron microscopy showed a decrease in the size of comedones, and loosened and desquamating horny cells in the comedones. From the above results, it could be concluded that Panax ginseng extracts might have effects on the keratinization process of the skin.

Histopathological changes under occulsive dressing with 0.1% triamcinolone acetonide cream, 0 025% fluocinolone acetonide cream, and 1% hydrocortisone cream were compared each other and with the changes following topical application of 5% ammoniated mercury ointment without occulsion in five cases of psoriasis vulgaris. 1) The earliest changes noticed were the diminution of the papillary edema, the appearence of the granular layer and the disappearence of parakeratosis. 2) A week after treatment, the remarkable changes revealed were the thinning of the epidermis, the diminution of acanthosis, papil]ary edema and cell infiltration of the upper dermis and the appearence of the granular layer. 3)The capillary dilatation remained unchanged even two weeks after treatment in all groups. 4) Among these drugs, the best respanse revealed was triamcinolone cream, the next was fluocinolone cream. The response of hydrocortisone cream was poorer than fluocinolone cream and ammoniated mercury ointment was even more poorer than hydrocortisone cream.

PURPOSE: Exercise is frequently recommended in the management of diabetes mellitus(DM) and can improve blood control by increasing insulin sensitivity and psychological benefits. Exercise can result in good glycemic control in type 2 DM, when combined with diet and drug therapy. However, in type 1 DM, the expected improvement in glycemic control with exercise have not been clearly established. Effects of exercise on glycemic control in patients with type 1 DM were investigated. METHODS: 20 patients with of type 1 DM, who were no retinopathy, neuropathy, nephropathy and cardiac disorders, were enrolled and exercised for 30min. with 50% of individualized maximum VO2. Blood sugar concentration were measured before, immediate and 15min after exercise. The results were evaluated with HbA1c, C-peptide and DM duration. RESULTS: Blood sugar concentration were significantly decreased from pre-exercise 198+/-9.7mg/dL to immediate 145+/-7.1mg/dL and at 15min. Post-exercise 134+/-4.0mg/dL(P<0.05). In case with HbA1c<10%, there was significantly decreased in blood sugar level from pre-exercise 176+/-9.7mg/dL to immediate 123+/-63.2mg/dL and at 15min post-exercise 113+/-1.9mg/dL(P<0.05). In case with HbA1c>10% there was also significantly decreased in blood sugar levels 222+/-64.7mg/dL, 169+/-6.1mg/dL, 157+/-1.2mg/dL respectively(P<0.05). Group with moderate decreased blood sugar(40-99mg/dL) was 8 patients(42.1%), group with mild decreased blood sugar(<40mg/dL) was 7 patients(36.8%) and group with decreased more than 100mg/dL was 4 patients(21.5%). There was no correlation in degree of decreased blood sugar concentration among HbA1c, C-peptide, DM duration. CONCLUSION: Proper exercise in type 1 diabetic children can decrease blood sugar level significantly and make good glycemic control and can decrease DM microvascular complications in addition to motivating physically active lifestyle.
