The frontal cortex of rat is innervated by dopaminergic pathway(mesocortical pathway) arising from ventral tegmental area. Several studies have suggested that mesocortical dopaminergic neurons may modulate the function of dopaminergic neurons at subcortical sites. The effect of lesions of the dopaminergic nerve terminals in the medial prefrontal cortex of the rat on dopamine D1 and D2 receptors within the striatum and olfactory tubercle has been investigated. Bilateral 6-hydroxy-dopamine lesions were stereotaxically placed in the medial prefrontal cortex. Animal were pretreated with desipramine to block the uptake of neurotoxin into noradrenergic terminals and to make it more selective for dopamine terminal. After 2weeks later, we examined the changes of D1 and D2 receptors in caudate-putamen and nucleus accumbens by quantitative autoradiography using the specific D1 antagonist [3H]SCH23390 and D2 antagonist [3H]spiperone. The results shows that D1 receptor at striatum was up regulated 2weeks after destruction of dopamine terminals within medial prefrontal vortex of the rat. This findings suggest that frontal cortical dopamine system may regulate the dopamine system in corpus striatum.

The purpose of this study was to assess the comorbid axis-II disorders of obsessive compulsive disorder(OCD) patients and to investigate the relationship between symptoms of OCD and the comorbid personality traits. The subjects were 59 patients who met DSM-IV criteria for obsessive-compulsive disorder and 32 normal controls. All subjects completed Personality Disorder Questionnaire-IV(PDQ-IV). The patients completed Beck Depression Inventory(BDI) and Beck Anxiety Inventory(BAI), and were rated with Yale-Brown Obsessive Compulsive Scale(YBOCS). The results were as follows. 1) The OCD patients showed significantly higher prevalence of avoidant, depresssive and borderline personality disorder(p<0.01) compared to controls. 2) The BAI score had significant effect on the avoidant personality score(t=3.23, p<0.003). The BDI score had significant effect on the depressive personality score(t=3.08, p=0.004). The YBOCS(t=2.10, p=0.043) and BAI(t=2.60, p=0.014)scores had significant effects on the borderline personality score. We found that OCD patients had higher prevalence of avoidant, depressive, and borderline personality disorders. We also found that obsessive-compulsive symptoms have significant effect on the severity of borderline personalty traits. We suggest that it would be very helpful to consider Axis-II disorders for managing patients with obsessive-compulsive disorder.

PURPOSE: The prognosis for early gastric cancer (EGC) is favorable, and the 10-year disease-specific survival rate is reported to be around 90%. The absolute number of recurred EGC is too small to assess the risk factors, so recruitment of a large number of cases for statistical analysis is very difficult. We carried out this study to analyze the incidence and the patterns of recurrence of EGC and to identify the clinicopathological risk factors for recurrence of EGC. MATENRIALS AND METHODS: The authors retrospectively investigated the follow-up records of 1418 patients who underwent a curative resection for EGC from Jan. 1984 to Dec. 1999 at the Korea Cancer Center Hospital and analyzed them with special reference to cancer recurrence. Results: In this retrospective study of 1418 cases, 43 patients died of a recurrence of gastric cancer, and 105 patients died of unrelated causes. The five-year and the ten-year overall survival rates were 89.6% and 81.7%, respectively, while the five-year and the ten-year disease- specific survival rates were 96.5% and 94.3%, respectively. The recurrence patterns of the 45 recurred EGC were hematogenous metastasis (19 cases), lymph node (L/N) metastasis (8 cases), locoregional recurrence (2 cases), peritoneal seeding (3 cases), and combined form (13 cases). The mean time interval to recurrence was 38.6 months, and the number of delayed recurred cases after 5 years was 10 (22.2%). Of the clinicopathologic factors, depth of invasion, L/N metastasis, macroscopic type, lymphatic invasion, and vessel invasion, were significant risk factors in the univariate analysis. However, in the multivariate analysis, only L/N metastasis was an independent prognostic factor. CONCLUSION: Based on the results of this study, L/N metastasis is an independent prognostic factor. Thus, in patients with node-positive disease, adjuvant therapy might be considered, and long-term close follow-up might facilitate early detection and treatment of recurrent disease due to delayed recurrence.
