PURPOSE: Platelet Rich Plasma(PRP) application is increasing with sinus inlay bone graft, but there is few research with radiographic ananlysis on effect of PRP in maxillary sinus. The author investigated the amount of bony changes of maxillary sinus for dental implantation among the patients with maxillary inlay graft. MATERIALS AND METHODS: With 10 patients who were treated with sinus inlay autologous bone grafting combined with PRP technique, and with 5 patients who were treated with sinus inlay grafting only without PRP, the panoramic radiographys which were taken at preoperation, immediate postoperation, 3months postoperation, and 4 months postoperation(a month after dental implantation)periods were analysed. The films had been scanned, and then proceeded throughout image analysis system. The bone density of maxillary grafted sites was compared with adjacent tooth enamel density and remeasured according to density luminosity of each film. The density changes on PRP group and bone graft only group were an lysed with non-parameteric statistics method. RESULTS: In PRP combined patients group, bone density on postoperation periods was increased totally. The remarkable enhanced change of bone density was observed on 3 months postoperation period, thereafter the increasing rate was slightly reduced . In only bone graft patients group, bone density on postoperation periods was also increased compared with preoperation period, but the bone density of 4 months postoperation period was decreased compared with 3 months postoperation period. The amount of bone density on PRP group was significantly changed according to periods in contrast to bone graft only group. CONCLUSION: The bone density on PRP group was remarkably increased at 3 months postoperation compared to bone graft only group and it was seemed to be associated with more new bone formation, less grafted bone resorption at bone grafted sites with PRP.

OBJECTIVE: It has been well known that alcohol can modulate several ligand-gated ion channel and voltage-gated ion channels. But the roles of alcohol in the autonomic neurons still remain unclear. In this study, thus we characterized the neuronal acetylcholine receptor (nnAChRs) and investigated the modulation of nnAChRs by ethanol (EtOH). METHODS: We used whole-cells which were acutely dissociated male rat major pelvic ganglion (MPG) neurons, and used gramicidin perforated patch clamp techniques. RESULTS: MPG neurons can be classified on the basis of the response of the soma membrane to depolarizing current pulses ; either tonic or phasic neurons. Sympathetic neurons expressing T-type Ca(2+) channels showed tonic firing pattern, while parasympathetic neurons lacking T-type Ca(2+) channels phasic firing to depolarizing current pulses. When hyperpolarizing currents were injected, sympathetic neurons produced post-anodal rebound spikes, while parasympathetic neurons were silent. Under current clamp mode, Acetylcholine (ACh) evoked significant membrane depolarization and produced subsequently marked membrane hyperporization. Under whole-cell mode, application of ACh-induced inward currents held at holding potentials below 0 mV and reversal potential was close to 0 mV, an equilibrium potential of nonselective cation channel. The ACh-activated current was blocked by methyllycaconitine (MLA ; 10 micrometer), hexamethonium (100 micrometer) and alpha-bungarotoxin (alpha-BuTx ; 100 nM), nAChRs antagonists. EtOH (40 mM) potentiated ACh-induced depolarization and hyperpolarization. EtOH also increased both alpha-BuTx-sensitive and -insensitive ACh-activated currents. Futhermore, EtOH potentiated 5-HT-activated current but had a little effect on GABA-activated current. CONCLUSION: These results suggest that EtOH modulates nnAChRs and 5-HT receptors in MPG neurons.

Thirteen patients were operated for cubital tunnel syndrome and followed for an average of 26 months postoperatively. Ten patients had a history of relevant trauma and three patients had degenerative osteoarthritis of the elbow. The average duration of symptoms was 18 months (range, 2 to 96 months). Diagnosis was made by physical examination, electromyography and nerve conduction study. Among these, nerve conduction study was found to be the most valuable diagnostic method for the patients with atypical clinical findings. Most of the operations were performed by anterior transposition of the ulnar nerve. At the most recent follow-up, the result was excellent in two patients, good in eight, and fair in three; thus ten patients(77%) showed satisfactory results. The rating system for ulnar neuropathy based on sensory, motor dysfunction and pain was useful for evaluating the operative results. The postoperative gain of score for pain and sensory function were larger than that of motor function. Factors known to influence the result of the operation (age, duration of symptom, history of trauma, method of operation) did not effect the outcome in this study. For successful operation, the ulnar nerve must be thoroughly examined, all possible levels of compression must be released and new foci of compression must be created.

Several microvascular anastomotic techniques have been described with methodical effectiveness, patency rates, healing state of microscopic findings. This experimental study presents the comparison of three types of arterial microvascular anastomotic techniques: end-to-end(ETE) anastomosis, end-in-end(EIE) anastomosis, and continuous technique. Sixty male Sprague-Dawley rats, 60 femoral arteries were used for this study. Twenty rats per each technique were used and sacrificed at post-operation 1 day, 3 days, a week, 2 weeks for scanning electromicroscopic findings. The patency was monitored by miniDoppler throughout total experimental periods. The anastomotic time on each method was measured to compare the technical effectiveness. The final results were as follows: 1. The anastomotic time for the end-in-end technique was significantly shorter than another techniques. The average time for each technique was measured as 15 minutes on EIE technique, 20 minutes on continuous technique and 25 minutes on ETE technique. 2. The patency rate for the end-in-end technique at 2 weeks also was superior to another techniques. The patency rate for each technique was demonstrated as 90 % on EIE technique, 85 % on ETE technique and 80 % on continuous technique. 3. The scanning electromicroscopic findings on healing condition of vessel endothelium during the observation period showed that the end results of EIE technique, ETE technique and continuous technique in sequence were good. The end-in-end technique proved to be the superior with regard to anastomotic time and patency rate when compared to end-to-end technuqe, so EIE techniqe might be well available for the case of large discrepancy of vessel size. The patency rate, microscopic healing findings in continuous technique were seen as the lowest level among the three anastomotic techniques, therefore the application of continuous technique was recommended only on the inevitable case.

The purposes of this retrospective study were to assess the change of serum parameters in oral and maxillofacial surgery patients after operation and to determine what laboratory parameters on treatment periods were associated with the recovery of systemic condition. For purposes of assessing systemic nutritional status, several serum parameters were chosen. The sample patients were randomsubjects extracted from three category patient groups- oral cancer, odontogenic abscess, facial bone fracture based on treated patients at department of oral and maxillofacial surgery in Pusan National University Hospital from September 1, 1998, to September 1, 2002. Each groups were consisted with 10 patients. Each patient chart was examined and blood sample parameters were reviewed with clinical signs, symptoms and vital sign at preoperative day, postoperative 1 day, postoperative 1 week. Several parameters were analyzed statistically for extraction of mean values and differences between the periods groups. The findings of serum parameters of cancer, abscess and fracture groups were as follows: 1. In cancer patients, Hb, MCV, albumin, cholesterol, LDH, AST, ALT, neutrophil, platelet, leukocyte, Na, K, Cl, BUN, creatinine were analyzed. Values of Hb, albumin, AST, neutrophil, leukocyte, Cl showed significantly differences according to periods. 2. In abscess patients, CRP, ESR, leukocyte, body temperature, neutrophil were analyzed. Values of CRP, leukocyte, body temperature, neutrophil showed significanlty differences according to periods. 3. In fracture patients, same arameters with cancer patient's were chosen. Values of platelet, Cl only showed significantly differences according to periods. 4. In cancer patients, data regarding correlation was analyzed statistically as Pearson's value. A positive correlation was found between Hb and albumin, K, Na(p<0.05). A positive correlation was also found between neutrophil and leukocyte(p<0.05). Positive correlations were found between cholesterol and ALT, LDH and platelet, creatinine both, Platelet and BUN, Na and K(p<0.01). 5. In abscess patients, Peason's correlation values were analyzed on parameters. A positive correlation was found only between CRP and neutrophil(p<0.05). 6. In fracture patients, The correlations of parameters also were statistically analyzed. Positive correlations were found between MCV and K, albumin and LDH, AST and three parameters of creatinine, Na, Cl, K and neutrophil, neutrophil and three parameters of leukocyte, BUN, K(p<0.05). Positive correlations were found between LDH and AST, ALT and AST, creatinine both(p<0.01). This retrospective clinical study showed the CRP levels only on abscess patients may be useful in determination of clinical infected status, but the levels of other parameters on cancer, fracture patients did not showed significant values as diagnostic aids for clinical status.

PURPOSE: Neoadjuvant chemotherapy is commonly used to treat cancer patients as adjunct treatment, but if the microvascular tissue transfer is performed simulataneously with cancer resection surgery, the induction chemotherapy might affect the survival rate of vascularized free flap. Our study will focus on the effect of induction chemotherapy on the free flaps which were made on white rat abdomen after injection of 5-FU. MATERIALS AND METHODS: The experimental rat groups were divided into three groups (total 24 rats) as a normal control group, 24 hrs group after 5-FU injection, 3 days group after 5-FU injection. Inferior abdominal island flaps of 8 Sprague Dawley rats on each group were made and immediately were induced into an ischemic state by clamping the supplying inferior epigastric artery and vein with microvascular clamp for a hour to induce a similiar free flap circumstance, then the inferior abdominal skin flaps were reperfused by releasing the clamps. The flaps on abdomen were repositioned and sutured. The experimental data for flap survival rate was collected by digital photo taking, analysed by computer image program to compare with the flap luminosity. The rats were sacrificed at 3 days, 5 days, 7 days after flap preparation and specimens of the flap were taken and stained with H-E staining. The microscopic finding was made under magnification of 200 and 400. RESULTS: 1. Gross findings on each groups showed the healing condition was good as following sequences; normal, 24 hrs group after chemotherapy, 3 days group after chemotherpy. 2. The values of flap luminosity for evaluation of flap survival rate also showed the same sequences as gross findings of healing state. 3. The microscopic findings of epidermis necrosis, inflammation state, dermis fibrosis, vessel change, fatty tissue layer thinning were compared with each group. The 3 days group after chemotherapy showed remarkably poor healing condition compared to other groups. CONCULSION: Chemotherapy agents affected the healing process of free flap, but healing condition was recovered spontaneously as post-injection periods passed out. In opposite to our expectation, 3 days group showed the bad flap condition in comparing with 24 hours group which was considered as immatured body circulation state of chemotherapy agent. It showed that 3 weeks in human being after chemotherapy was not proper as timing of microvascular tissue transfer if 3 days group in rat was considered as same healing period of 3 weeks in human being. More delayed healing timing than 3 weeks might be required in clinical application of free tissue transfer.

Jessner's lymphocytic infiltration of the skin (JLIS) is a well-known but poorly understood disorder. Some doubt still exists about whether it is a distinct disease or a variant of lupus erythematosus or, less commonly, polymorphous light eruption, cutaneous lymphoid hyperplasia. An effective therapy is still unavailable for JLIS. We report a patient with JLIS which was successfully treated with dapsone and intermittent systemic glucocorticoid therapy.
