Injury to specific areas of the immature brain, in both the human and animals, can result in compensatory reorganization in undamaged adjacent or contralateral areas. The functional plasticity of such compensatory hypertrophy is not well known, but in some cases may be responsible for recovery of function. In order to investigate the effect of unilateral ischemic injury on the contralateral cerebral hemisphere in neonatal rats, early and late changes in various areas of both cerebral hemispheres were assessed. Seventy-seven seven-day-old Sprague-Dawley rats underwent unilateral carotid artery ligation and were then exposed to hypoxia(8% oxygen) for 3 hours. The animals were killed one week(Group I, 58 rats) and three months(Group II, 19 rats) later. Twelve rats, comprising Group III, were exposed to hypoxia for 3 hours without carotid artery ligation. The control group, consisting of 19 rats, did not undergo any of the above procedures. In each slice of brain tissue(4mm posterior to the bregma), the area of the whole brain, each hemisphere, and the frontoparietal, temporal and hippocampal regions in each hemisphere were measured, using the image analysis program(Optimas 5.2), and to assess which regions were affected, proportions of each hemisphere occupied by each region were compared. In Group II, the proportional areas of the frontoparietal(p<0.05) and temporal(p<0.01) regions in the contralateral hemisphere increased significantly, compared with the control group, but the hippocampal region showed no significant change. In Group I, there was no contralateral hypertrophy. The ipsilateral hemisphere showed significant atrophy and there was weight reduction in Groups I(p<0.001) and II(p<0.001). This study suggests that unilateral hypoxia-ischemia results in ipsilateral hemispheric atrophy and contralateral hypertrophy, especially in the frontoparietal and temporal areas, may contribute to some functional recovery and compensation in addition to uncrossed corticospinal or other descending motor systems.

Uterine didelphys is a congenital malformation characterized by the presence of two separated hemiuteri andhemivaginas, due to lack of midfusion of the Mullerian ducts. We report a case of UD-BHRA(uterine didelphys withblind hemivagina and ipsilateral renal agenesis), a rare type of uterine didelphys charaterized by symptomaticunilateral hematocolpos due to blind hemivagina after menarche and ipsilateral renal agenesis. The MRI findings in22-year-old woman with bilateral ovarian tumors demonstrated two separated uterine horns and cervical and vaginalcanals, with left hematocolpos and left renal agenesis.

The case of a 27-year-old woman with an ectopic pancreas in the stomach, presenting as a cystic abscess formation, is presented. Physical examination revealed severe epigastric pain with a high fever. Laboratory data showed leukocytosis. A computed tomographic (CT) scan demonstrated a cystic mass adjacent to the gastric antrum. Endoscopy disclosed a submucosal mass at the antrum. With the diagnosis of a cystic mass laying near the gastric antrum, a laparoscopic approach was taken initially. An inflammatory abscess containing a cystic mass was found at the gastric antrum, so a partial gastrectomy was performed. Histological examination revealed an ectopic pancreas with cystic abscess formation. A review of the literature published in English showed that this case was an example of a rarely reported complicated change of an ectopic pancreas in the stomach.

BACKGROUND: Reactive oxygen species (ROS) are free radicals that induce lipid peroxidation and cause tissue damage. ROS are frequently produced by ischemia and subsequent reperfusion in clinical situation and like coronary artery bypass graft surgery and transplantation. More over, some anesthetics are known to act as an antioxidants and free radical scavenger and, the aim of this study was to explore the scavenging effects of thiopental and ketamine against ROS induced by isolated rabbit thoracic aortic endothelial damage. METHODS: Twenty white male rabbits (weighing 2.0-2.5 kg) were used. Thoracic aorta and were dissected free, cut into rings (3-4 mm), and suspended in an organ bath filled with 10 ml Krebs solution bubbled with 5% CO2 and 95% O2 at 37oC. The rings were equilibrated for 90 min and the solution changed every 15 min, and then a resting tension of 1.5 g was applied to the rings. Isometric tensions were recorded using a transducer connected to a data acqusition system (Biopac Inc. USA). Aortic rings were precontracted with norepinephrine (NE, 10-6 M), and changes in tension were measured after the cumulative administration of acetylcholine (ACh 3 x 10-7, 10-6 and 3 x 10-6 M) and nitroglycerin (NTG 10-5 M). Data are expressed as percentages of the 10-5 M NTG-induced relaxation (ACh/NTG). Percentages of ACh/NTG, before and after ROS exposure by electrolysis were noted for control and experimental groups. Aortic rings were pretreated with thiopental (3 x 10-5, 10-4 and 3 x 10-4 M, n = 9, 13, 17), ketamine (10-4 M, n = 8), catalase (1000 U/ml, n = 12), mannitol (3 x 10-4 M, n = 5) or not pretreated (free, n = 6). After 30 minutes, with the rings were exposed to ROS by electrolysis (DC 9 V, 20 mA, aortic rings 1 cm removed from the anode) in Krebs solution for 2 minutes. After electrolysis, the organ bath fluid was replaced with fresh Krebs solution, and the aortic rings were precontracted with NE and was vasorelaxation with ACh and NTG as above mentioned concentrations. RESULTS: Endothelium-dependent vasorelaxation was induced in all concentrations of thiopental groups in a dose-dependent fashion (P <0.05 vs control value) even with ROS attack. The catalase group produced vasorelaxation after ROS attack (P <0.05 vs control value). On the other hand, no ACh-induced significant endothelium-dependent vasorelaxation after ROS exposure was observed in the ketamine and mannitol pretreated group, or in the free group (P <0.05 vs control group). CONCLUSIONS: These findings suggest that thiopental and catalase preserve ACh induced endothelium-dependent vasorelaxation and that thiopental has a dose-dependent ROS scavenging effect like catalase.

BACKGROUND: Anesthetic technique for laryngeal microscopic surgery should be focused on rapid recovery of deep anesthesia and full muscle relaxation. This study was taken to evaluate the effect of continuous infusion of propofol and succinylcholine for this kind of anesthetic goal. METHODS: Forty patients scheduled for laryngeal microscopic surgery of short duration(15 min) were randomly allocated into two groups. Anesthesia was induced and maintained with either propofol(2.5 mg/kg followed by a continuous infusion of 0.1 mg/kg/min) in group P or with thiopental (5.0 mg/kg) and inhalation of 1~2 vol % enflurane for maintenance of anesthesia in group T/E. Succinylcholine(1 mg/kg followed by continuous infusion of 0.1 mg/kg/min) was administered to facilitate tracheal intubation and maintain neuromuscular blockade. RESULTS: No significant difference of duration of anesthesia appeared between two groups. Additional doses of succinylcholine were needed in 10% of group P and 30% of group T/E (p<0.05). In group P, time to response to suction catheter(136+/-54 vs 232+/-116 sec), time to eye open spontaneously or to verbal commands (368+/-142 vs 549+/-165 sec) and time to extubation (454+/-117 vs 647+/-181 sec) were significantly shorter comparing to group T/E. The quality of awakening was more favorable in group P(p<0.05). Laryngeal suspension induced bradycardia in 15% of group P and in 5% of group T/E. Both group P and group T/E (10% vs 30%) needed esmolol infusion to control the blood pressure during surgical procedure. CONCLUSIONS: Rapid recovery of anesthesia and muscle relaxation can be expected after continuous infusion of propofol(2.5 mg/kg followed by 0.1mg/kg/min) and succinylcholine(1 mg/kg followed by 0.1 mg/kg/min) supplemented with 50% N2O in 50% O2 for short duration of laryngeal microscopic surgery.

PURPOSE: The purpose of this article is to study whether the Doppler ultrasound differentiate obstructive hydronephrosis from nonobstructive hydronephrosis in sonographically diagnosed hydronephrosis. MATERIALS AND METHODS: We studied 35 kidneys of 27 patients with hydronephrosis which were diagnosed with sonography. Resistive indices were calculated from Doppler waveforms at the level of interlobar or arcuate arteries. We divided the materials into two groups with obstructive and nonobstructive hydronephrosis according to the findings of intravenous pyelography, retrograde pyelography, and anterograde pyelography. These were compared with normal control group(20 kidneys in 10 persons). We also grouped patients regarding to the duration after onset of clinical symptom, and graded the hydronephrosis into three group according to sonographic findings. We analyzed the correlations of the above sonography and clinical findings with resistive index. Hydronephrosis was obstructive in 20 kidneys(in 17 patients) and nonobstructive in 15 kidneys(in 10 patients). RESULTS: There was statistically significant difference between the mean resistive indices in obstructive hydronephrosis(0.74 +/- 0.02) and that in nonobstructive hydronephrosis (0.60 +/- 0.02)(p<0.05). Also there was no difference between the mean resistive indeces in nonobstructive hydronephrosis and that in normal control group(0.59 +/- 0.07)(P > or = 0.05). CONCLUSION: The use of Doppler sonography can be helpful in detecting the presence or absence of true obstruction in patients with hydronephrosis.
