유리 측두 - 두정 근막이식을 이용한 수부 복합조직 결손의 재건술

In hand resurfacing, the temporoparietal fascia is one of the most ideal donorflaps in terms of thin, pliable and well vascularized sheets of tissue. It leaves an inconspicuous donor site morbidity within the hair bearing scalp. In addition, microvascular transfer is facilitated the axialpatten flap with consist, reliable and large calibered vascular pedicles. It should carry a good intrnisic blood supply to improve local conditions for healing and to decrease bacterial contamination of the wound. Secondary reconstructive surgery can be safely performed beneath the flap. We have experienced 4 cases of reconstruction of full thickness skin and tendon less in the hand using temporoparietal facial flap with skin graft. In two cases, we did a tendon graft using fascia lata with temporoparietal fascial flap. For these two, we saw a satisfactory functional recovery as well as good coverage for the defect. For the other two case, we did only the temporoparietal fascial flap and got satisfactory coverage. Coverage was provided without moable complications.

The thrombus formation is the most common cause of vessel obstruction after microvascular anastomosis and the change in the vessel wall is the most important factor in pathogenesis of thrombus formation. In the proximal portion of the ligated side branch of the artery, development of hypertension and turbulent flow with resultant continuous hemodynamic stress on the arterial wall could be expected. the histology of the arterial wall could be changed as a result of hemodynamic stress and such histologic changes could have an effect on the thrombus formation after microvascular anastomosis. In this study, the superficial epigastric artery of a rat, which was side branch of the femoral artery was ligated (5 rats, 10 speciments in each group). The specimen was obtained from the proximal portion of the ligation after specific time elpase and stained with H & E and vicyoria blue and observed under the light microscope (3 hours, 1, 3 days, 1, 2, 4 weeks). The following results were obtained. 1. Duration of ligation of less than 3 days resulted in the inflammatory cell aggregation and congestion of capillaries around the artery. There were no other specific findings. 2. From 1 week after ligation, intimal thickening due to subendothelial hyperplasia began and increased as further time elapsed but without statistical significance (P>0.05). 3. The incidence of intimal thickening due to subendothelial hyperplasia was higher at the site near to ligation (P<0.05). 4. From 2 weeks after ligation, many elastic fibers were observed as an extracellular component in the thickened intima. 5. Changes within the tunica media and advantitia were not found.

The radial forearm flap has proved to be a reliable and versatile free flap in many areas of reconstructive surgery, especially head, neck and extremity reconstruction. Much of this reliability results from the constant vascular pattern of the forearm and the large size of vessels which greatly simplify the technical aspects of microsurgery. Furthermore, the flap is thin, pliable easily available in variable sizes and can be used as a composite flap with vascularized nerve, bone of tendon. This paper presents the our clinical experience of 9 patients to whom underwent reconstruction of soft tissue by using free forearm flap.

A number of methods are available for scalp reconstruction : skin graft, local flap, distant pedicle flap and free flap. Each of these has well defined roles, advantages and limitations according to nature and extent of the defect. Free flap, especially latissimus dorsi muscle flap is preferred for reconstruction of extensive scalp defect because it is the largest single muscle available for free transfer as well as it has constant anatomy and long large size of vessels which greatly simplify the technical aspects of microsurgery. Furthermore, it can control infection and also the donor site morbidity is minimal. We have been experienced 2 cases of reconstruction of extensive scalp defect using free latissimus dorsi muscle flap with skin graft. A robust coverage was provided without notable complications.

Ethylene is Known to have properties such as retardation of longitudinal growth and leaf expansion, increase in stem thickness, and stimulation of overall growth. This experiment was conducted to provide the background for application of beneficial properties of ethylene to bean sprouts production. Samples were put on the treatment for 4 days total and alt the parameter were measured at 5th day of the experiment. The results are as follows : Mean body length from upper part was decreased 2.2cm, but middle part and lower part were rather increased 1.5cm and 0.2cm, respectively, compared with the mean values of controls. Mean difference in stem thickness for upper, middle, and lower part of the stem were 0.5mm, 0.4mm, and 0.2mm respectively. Especially, it is a great way to change shape of the bean sprout in desired way without using any chemicals, such as pesticides or growth stimulation reagent.

뇌실내 TRH(Thyrotropin-Releasing Hormone)에 의한 이자 외분비 항진 기전에 관한 연구

Thyrotropin-releasing hormone (TRH) may play a physiological role as a neurotransmitter or a neuromodulator in addition to its hormonal role. It is diatributed not only in the hypothalamus but also in extrahypothalamic tissues including pancreas and gastrointestinal tissue. But limited studies suggest that TRH can stimulate pancreatic secretion and a paucity in information and controversy still remain. Therefore, in the present study, the mechanism of the intracerebroventricular (i.c.v.) TRH-induced pancreatic exocrine stimulation was investigated in rat pancreas in relation to central vagal factor, gastric acid factor, duodenal factor and local vagal reflex affecting secretory mechanism of exocrine pancreas. I.c.v. injection of TRH (3 ㎍) stimulated the amylase and protein secretion. The effect reached maximum at 30 minutes and returned to basal level at 90 minutes after administration. But pancreatico-biliary flow was little affected. Th effects of TRH were blocked by bilateral vagotomy and posterior truncal vagotomy, but not by anterior truncal vagotomy. Procedures of the pylorus ligation and the resection of pyloroduodenal junction also blocked TRH-induced pancreatic secretion. However, treatment with cimetidine, L-364,718 (a selective CCK antagonist) or reconnection of pyloroduodenal junction had small or no effect on TRH-induced pancreatic secretion. These results suggest that the central TRH stimulates the pancreatic exocrine secretion, which is mediated mainly via vagus, especially posterior vagal trunk.
