In order to measure the MPD with 8-methoxypsoralen, we selected 49 Korean healthy male vlunteers without phototoxic or photosensitive dermatoses. They were divided to 3 groups (Immediate; group 1, 1 hour; group 2, 2 hours', group 3) according to the waiting time, intervals of application of photosensitizer a,nd UVA:irradiation. The reaults were summarized as follows: 1. MPDs of group 1 had no clinical significance. 2, MPDs of group 2 were more than those of group '3 independently of application methods of photosensitizer. 3. In the cases of topical application of 8-MOP, MPDs of group 3 according to reading interval (24 hours, 48 hours and 72 hours after UVA irradiation) were 3.4+/-2.9 J/cm2, 1.9+/-l.5 J/cm' and l. 7+1, 2/cm, respectively. 4 In the cases of oral administration of 8-MOP, MPDs of group 3 according to reading; interval as topical application of 8-MOP were 7.1+/-2.3 J/cm, 4.4+/-1.1 J/ cm2 and 4.2+/-l.2 J/cm2, respectively. 5 MPL)s accarding to the skin types as follows; (waiting time; 2 hours, read- ing interval; 48 hours) a. In the case of topical application of 8-MOP, MPDs of the skin type ]II, 1V and V were 0.9+/-0.5 J/cm2, 1.8+/-1.1 J/cm2 and 3.0+/-l.3 J/cm2 respectively. b. In the case of oral administration of 8-MOP, MPDs of skin type g, W and were 3.5+/-1.1 J/cm2, 4.7+/-1.3 J/cm2 and 6.9+/-l.8 J/cm2, respectively.

Restoration of functional and anatomic changes of kidney in UPJ stricture is one of most important subjects in urology. A clinical observation was made on the 28 cases (29 kidneys) of pyeloplasties for UPJ stricture from Jan. 1976 to Dec. 1981. Of them 20 cases (21 kidneys) were followed up for more than 6 months postoperatively. The following results were obtained; 1. The patients in this series were 22 males and 6 females, and 11 children and 17 adults. The left side was 3 times more frequently affected than the right. They symptoms on admission were mostly flank pain, palpable mass, and etc. 2. Preoperative status of UPJ was; UPJ stricture alone in 20, UPJ stricture with aberrant vessel in 4, UPJ stricture with stone in 3, and UPJ stricture with vesicoureteral reflux in 1 case. 3. Preoperative grade of hydronephrosis was closely related to each other in the functional and anatomic aspects of kidney. In general, children showed relatively more advanced hydronephrosis than adults and the degree of improvement of hydronephrosis postoperatively was similar to each other. 4. Anderson Hynes' method of pyeloplasty in most cases (20 kidneys) and simple pyeloureterostomy in 9 kidneys were performed, and results between both operations showed no difference. But Anderson Hynes' method was more effective in marked hydronephrosis such as giant hydronephrosis and simple pyeloureterostomy in mild hydronephrosis. 5. In cases in which UTI was present preoperatively, postoperative UTI tended more to persist than in those not complicated with preoperative UTI, and in both sides postoperative UTI mostly persisted for 2 months and disappeared within 6 months. 6. The period of nephrostomy and ureteral stent was not directly related to postoperative results, but nephrostomy without ureteral stent relatively showed good results. 7. Postoperative complication was UTI in 2, re-do pyeloplasty in 1 and secondary nephrectomy in 1 case. 8. Improvement Of hydronephrosis continued for about a year after operation. It is recommended that more careful attention should be paid for the first year and be continued to watch for consecutive 2 years.

A lg year-old female patient with pityriasis lichenoides et varioliforrnis acuta (PLEVA) was been treated with PUVA, At first, she was treated with tetracycline for 8 weeks with improvement somewhat. But 2 months later, her skin lesions aggravated slowly. So, we tried to treated her with PUVA and then she was cleared completely. The initial dose of UVA was 5 J/cm The UVA dosage increased by 10g of the previous exposure and increased to the maximum dose, 15 J/cm The patient exposed to UVA R times per week. 12 times after the PUVA therapy, the skin lesions begin to improve and completely improved at 21 times of Pl.JVA therapy. She was followed up every week and there was no side effect except hyperpigrnentation till 24 months. The total dose during treatment is 210 J/cm.

A2 D time, a time interval from aortic second heart sound to the D point of mitral valve echogram, was reported as a valuable index of the left ventricular relaxation in its early diastole. It was suggested, however, that A2D time is influenced by variable factors rather than single factor. This study was performed to evaluate the influences of several on the A2D time and to extend our understandings in A2D time. For this purpose, A2D time was measured in 4 groups whose hemodynamic states were different, i.e.31 normal subjects (group A), 32 patients with essential hypertension without decompensation (group B), 10 normotensive patients with clinically full blown congestive heart failure (group C), and 11 patients with hypertensive heart failure (group D), and the mean values of each group were compared between the groups. Concordantly systolic hemodynamic parameters were observed and the relationship of A2D time and each of these parameters were observed. A2D time was consistently influenced by the level of left ventricle impedance and it is well correlated with parameters representing left ventricular systolic performances. In hypertensive subiects, A2D time was increased before the deterioration of the left ventricular systolic function but shortened after clinical heart failure. These findings suggest that A2D time may be of value in longitudinal follow-up of the left ventricular function in the hypertensive patients even before the development of clinical heart failure.

There have been increasing interests of diabetes in the realm of plastic surgery due to problems like foot ulcer as a complication, delayed wound healing or higher failure rates of flap surgery. Main pathology in diabetes is microvascular compromise as well as metabolic derangements. The disturbance in microvascular circulation results in ischemic environments in the body and acts as a main factor that determines the limit of reconstructive or aesthetic plastic surgery. A useful method to overcome such problems is the use of hyperbaric oxygen therapy, which is known to be effective in the treatment of ischemic skin ulcer or osteoradionecrosis. However, there have been few studies on the survival of diabetic random skin flap or the effects of hyperbaric oxygenation directed to increase survival of such flap. In our study, we supposed that the survival of diabetic random skin flap was diminished owing to compromised microvascular pathology and blood rheology, and metabolic derangements, so we hypothesized that hyperbaric oxygen therapy has both reversible and irreversible effects on the survival of ischemic random skin flap in Streptozotocin-induced diabetic rats. Increase of local transcutaneous oxygen concentration, O2 affinity in blood and dysmorphogenesis of red blood cells are reversible and relatively short-term effects and promotion of neoangiogenesis is irreversible or long-term effects. We intended to confirm that hyperbaric rats and to compare the effects between preoperative and postoperative hyperbaric oxygenation on the survival of such flap. And we expect the additional effects of hyperbaric oxygenation on metabolism in diabetic rat, such as lowering the blood glucose level and solving the arrested weight gain. We divided Streptozotocin-induced diabetic rats into three groups: the first was non-treatment diabetic group, the second was preoperative hyperbaric oxygen treated diabetic group(100% O2, 2 atm, 90min, 15sessions, twice a day), and the third was postoperative hyperbaric oxygen treated group(100% O2, 2atm, 90min, 15sessions, twice a day). After elevation of random skin flap on dorsum of diabetic rats, we evaluated the extent of flap survival by measuring the necrotic areas at 3rd, 7th, 10th, and 13th postoperative days. At that time, we intended to evaluate both effects on flap survival by preoperative and postoperative hyperbaric oxygen therapy. As a result, flap survival of non-treated diabetic group was 41% at 13th postoperative days. In diabetic groups with preoperative and postoperative hyperbaric oxygen therapy, flap survival were increased to 64.6% and 62.4% respectively. Diabetic groups with hyperbaric oxygen therapy have a tendency of meaningful decrement in blood glucose level. However, there were no meaningful differences between preoperative and postoperative hyperbaric oxygen therapy. Hyperbaric oxygen therapy has no effective correlations with body weight changes. We conclude that hyperbaric oxygen therapy has some useful effects on the survival of diabetic random skin flap.
