Adhesion formed between tendon and its sheath after repair often impairs functional recovery. There have been many attempts to reduce adhesion around a repaired tendon, but most results have been unsatisfactory or impractical in clinical application. Moreover, most attempts were focused on extrinsic tendon healing. whereas studies on the intrinsic tendon healing are sacrce in the literature. We have previously reported that fibrotic tendon adhesion after repair was decreased by decorin, a natural inhibitor of TGF-beta. Accordingly, the serial tensile strength was measured after complete tensection and repair of the tendon severance in order to confirm the effect of decorin inhibition of intrinsic healing capability. Forty White Leghorn chickens were subject to complete transection and repair of the third toe flexor digitorum profundus tendon in Zone II. In the experimental group, 0.5ml of diluted decorin(50microgram/ml) was injected around the repaired site, and the same volume of saline solution in the control group. Tendons were harvested at 1, 3, 5 and 7 weeks. The disrupting force of the repair site was analyzed using tensiometry(LLOYD LR 30K, U.K). The tensile strength of repaired tendon was similar in both groups for all postoperative periods. This indicates that intrinsic healing proceeds normally within the decorin group in spite of the blockade of TGF-betaactivity. Decorin, a natural inhibitor of TGF-beta, showed a significant inhibitory effect on reducing post-repair tendon adhesions, without disruption of intrinsic healing in the chicken flexor tendon injury model. Therefore, decorin is expected to be a useful agent for preventnion on tendon adhesion after the repair in clinical usage.

Background: Cerebral palsy is due to static encephalopathy during perinatal period. Selective dorsal rhizotomy (SDR) involves selective division of posterior nerve roots to reduce spasticity and improve function in children with spastic cerebral palsy. Anesthesia during SDR must preserve muscle contraction in response to direct electrical stimulation of the dorsal nerve roots. We did this study to get the better management of anesthesia for SDR. Methods: Anesthetic records were reviewed for 16 patients who underwent SDR during January 1996 to August 1997. Demographic data; anesthetic drugs and doses; changes of vital signs and end tidal CO2; dorsal root stimulation; postoperative pain control were analysed. Results: The mean age of patients was 4.9+/-1.7 years old. The mean weight was 16.3+/-4.0 kg. The under 1 MAC concentration of isoflurane and 2~3 mcg/kg/hr fentanyl did not interfere with electrophysiologic monitoring. Esophageal temperature was increased significantly during electrical stimulation of dorsal roots. End tidal CO2 concentration had a tendency to increase after electrical stimulation too. Direct installation of 10~15 mcg/kg intrathecal morphine prior to dural closure, and postoperative 0.5 mcg/kg/hr fentanyl had a good postoperative analgesia without complication. Conclusions: Isoflurane and fentanyl during anesthesia, and intrathecal morphine with continuous infusion of fentany postoperatively are suggested a good anesthetic method for SDR.

Allergic contact dermatitis that is attributable to contact with environmental sensitizers boine by a second individual, especially in marital or sexual relationships, has been described as connubial contact dermatitis. Severely pruritic multiple erythematous plaques, vesicles and bullae in a 35-year-old woman occurred on the face, posterior area of the neck, breasts, buttock, and both upper arms. No direct contact to allergens was obtained. However her husband had eaten some cooked sprouts from a lacquer tree for lunch at a restaurant the day before her eruption, then he caressed her that night. A patch test with extracts of lacquer tree in ethanol(2%), crushed extracts of lacquer tree (as is), and urushiol(0.002% pet.) on the patients back showed strong positive reactions.

Ectopic pregnancy refers to gestation in which the fertilized ovum implants on any other tissure than tbe mucus membrane lining the uterine cavity. Cornual (intertitial) pegnancy is a relatively uncommon but potentially catastrophic form of ectopic pregnancy, defined as implantation in the intramural portion of a fallopian tube. A hydatidiform mole usually occupies the uterine cavity but it's occurrence in the uterine tube is extremely rare. Only a few cases of primary hydatidifm mole of the tube have been reported. We experienced a case of ectopic hydatidiform mole in the uterine cornua and so present it with brief review of literatures.

We herein report a case of occupational contact urticaria syndrome induced by cefotiam di-hydrochloride in a nurse. She had generalized pruritic wheals accompanied by palpitations and tachypnea during the preparation of cefotiam solution. A scratch patch test with cefotiam di-hydrochloride, a major component of cefotiam ingredient showed multiple erythema and wheals within 5 minutes, accompanied by palpitations and tachypnea. No delayed type reaction was observed. Based on her clinical history and scratch test result, we diagnosed her condition as contact urticaria syndrome caused by cefotiam.

It is desirable to use more safe, objective, non-invasive method than visual scoring for the evaluation of irritation reaction and determine the optimum eoncentration of sodium lauryl sulfate(SLS) as a positive irritant control in routine patch test. In this study, SLS was applied to the volar forearm of ll non-atopic, healthy volunteers in concentrations of 0.5, 1.0, 2.0, and 5.0% under occlusion for 24h. The blood flow in test sites exposed to SLS was tecorded by laser Doppler velocimetry (LDV). The test sites were scored visually and the skin blood flow was measured at 24h, 48h, and 72h after the application of FiLS. We obtained the following results,' 1. There was a good correlation between visual scoring and skin blood flow using LDV(p = 0.4547). 2. 5.0% SLS could be used as a positive irritant control in routine patch test (p<0,05).

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

We examined the anatomical position of the mental foramina in mandibles foramen normal adult Koreans. 1. The percentages obtained from the study of the relationships between the mental foramen and the lower teeth showed that the most common location was type lv in which the mental foramen lay at the apex of the second promolar. The foramen between thr apices of ice two premolars (type lll) and the foramen between the second premolar and the first molar (type v) occured often and less often rspectively and find no foramen mesial to the first premolar or at the apex of the first premolar and posterior of the first molar (type l, ll, vl). 2. The study of relationship of the mental foramen to the bo of the mandible revealed that mental foramen was situated closer to the lowed border of the mandibular body. The distance ratio between the mental foramen and the alveolar crest to that between the mental foramen and the lower border was approximately 1.2 : 1. The height of the mandibular body was 31.09±2.80mm on the left side and 30.97±2.48mm on the right. 3. The distance from the mandibular symphysis to the anterior border of the mental foramen measured 29.52±2.01mm on the left, 30.82±2.04mm on the right side, and from the mandibular symphysis to the posterior border of the mandibular ramus was 104.20±4.74mm on the left, 105.44±4.49mm on the right side. It indicates that the mental foramen lies approximately at one-fourth of the distance from the mandibular symphysis to 2017-04-19 the posterior border of the ramus. 4. The distance from the superior border of the mental foramen to the bottom of the lower second premolar socket was found to be positive. It was 5.46±3.09mm on the left, 5.73±3.03mm on the right side. This indicates that the bottom of the lower second premolar socket is slightly higher than the superior border of the mental foramen.
