A case of malignant melanoma is described. The patient, 67 years old male, had thumb tip sized two tumor masses with linear arcuate spread on left upper back near spine of 3 months duration, and metastatic lesion on right axillary lymphnode. Lesions were removed surgically and split skin graft was done.

The one case of sparganosis is described, the patient, 45 years old male, had adult fist sized tumor mass on scrotum for 3 year's duration and removed 4 adults sparganum mansonoides by surgical operation. Attention is calIed to the importance of sparganosis in subcutaneous swelling or tumor because of to took lived snake or non-boiling water in customary at Korea.

The authors retrospectively analysed the ultrasonographic findings of 43 cases of surgically confirmed hypertrophic pyloric stenosis and their postoperative findings of sonograms taken at 1 month(n=40) or 3 months( n=5) after pyloromyotomy. In preoperative study, the thickened pyloric muscle was isoechoic or slight hypoechoic relative to liver on the midline longitudinal view and appeared as a "nonuniform acoustic ring" on the transverse view. The results of measurement in the all cases with hypertrophic pyloric stenosis were the pyloric thickness ≥3.8mm, the pyloric diameter ≥14mm, the pyloric channel length ≥16mm, the pyloric muscle volume ≥2.21Cm

PURPOSE: The purpose of this study was to evaluate the CT features of second branchial cleft cysts. MATERIALS AND METHODS: We retrospectively analyzed the computed tomographic images in nine cases of second branchial cleft cyst which was confirmed pathologically. Emphasis was on localization of the masses to fascial spaces as defined by the deep cervical fasica. RESULTS: In all nine cases, the lerions were located in the submandibular and carotid spaces. Among these cases, six(67%) had simultaneous involvement of the other contiguous spaces, such as anterior and posterior cervical spaces. All cases had round or oval, unilocular, cystic masses with partial or complete rim enhancement. In eight cases(89%), smooth and thin walls were observed. In one case, thick wall and septations were noted. No definite calcifications were noted in all cases. The internal contents of cystic masses showed relatively homogeneous appearance, and CT number ranged from 20 to 35.2 Hounsfield unit(HU)(mean, 28.4HU). CONCLUSION: CT diagnosis of second branchial cleft cyst would be easily obtained from recognition of frequent simultaneous involvement of the other contiguous spaces, along with a typical location and characteristic morphology.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Recent laboratory data indicate that the adenosine during the ischemic period may trigger protection via A1 or A3 adenosine receptor and also protein kinase C(PKC) plays a central role. This study was designed to determine the role of adenosine receptor subtypes and PKC in the preconditioning protection. METHODS: All cat heart groups were subjected to 40min ischemia and 30min reperfusion. The preconditioning protocol consists of 4min ischemia and then 10min of reperfusion 4 times. The effects of ischemic preconditioning, nonselective adenosine receptor blocker(SPT), an A1 specific antagonist(DPCPX) and protein kinase C inhibitor(Polymyxin B), on ischemic preconditioning were determined by infarction size. There were 5 groups : (1) control group (Group 1, n=10)(2) Ischemic preconditioned group(Group 2, n=9)(3) DPCPX pretreatment group(Group 3, n=6)(4) SPT preteatment group(Group 3, n=6)(5) Polymyxin B pretreatment group(Group 5, n=6). SPT and DPCPX were given intravenously 5 min before ischemic preconditioning. Polymyxin B was administered to cats for 30min during ischemic preconditioning period. RESULTS: Ischemic preconditioning only or pretreatment with DPCPX prior to preconditioning demonstrated a significant reduction in infarct size(22.6+/-1.5, 25.4+/-0.9% infarction of the risk zone, respectively, p<0.05) with respect to control, SPT-pretreatment, and polymyxin B-pretreatment groups(44.0+/-1.7, 43.0+/-2.0 and 40.3+/-0.4% infarction of the risk zone, respectively). CONCLUSIONS: Ischemic preconditioning protects heart from subsequent ischemia. Protection was blocked by SPT and protein kinase C inhibitor(polymyxin B), but not by A1 antagonist DPCPX. The cardioprotective effects by ischemic preconditioning in the in vivo cat heart appear to be dependent on A3 adenosine receptors and activation of protein kinase C.
