OBJECTIVES: The aim of this review article is to consider conceptual models of psy-chotherapy aff-ecting the brain. METHODS: Discuss the article by Eric R. Kandel describing the influence of psycho-therapy on the brain. CONCLUSIONS: Psychotherapy effects on memory system(conscious or unconscious) and other areas of the brain bringing structural and/or functional changes. It means that the brain and mind is not two but one, that is "mind is the function of the brain". The future task of 21st century psychiatrists is the integration of the brain biology and psycho-ther-apy: to explore the "biology of psychotherapy" or "psychotherapeutic effects of biological therapies".

OBJECTIVES: The objective of this article is to clarify the similarities and differences between psychiatry and neurology. METHODS: The author reviewed articles regarding the reciprocal relationship of psychiatry and neurology in Korea and western countries. RESULTS: The divided domains of psychiatry and neurology according to mind/body dualism is arbitrary and wrong. Mind is the function or activity of brain. Psychiatry is a branch of medicine which treats the mind disorders (dysfunction of the brain) caused by various biopsychosocial factors. Neurology is also a branch of medicine which treats the anatomical or structural abnormalities of the brain. Progress in the neuroscience and other disciplines heralds a new understanding of the brain leading to new approaches to neuropsychiatric disorders. CONCLUSION: Integration of the two disciplines is desired for mutual benefits and their patients' benefits near future in Korea.

Changes in the number, the immunoreactivities and the ultrastructures of sero- tonin immunoreactive mucosal mast cells[MMCs] in rat gastrointestinal tracts after vagus nerve stimulation were investigated by using light and electron microscopic immunocytochemical methods. The vagus nerves were electrically stimulated with a square wave pulse generator for a duration of 5 minutes each, a total of 8 times at 2 minute intervals. Serotonin immunoreactive cells of the connective tissues of the gastrointestinal tract were mainly located in the lamina propria, and a small number of the cells were also scattered in the submucosa. By using electron microscopic immunocytochemistry and Wright stain, the serotonin immunoreactive cells of the lamina propria and the submucosa were identified to be MMCs. A few large-sized serotonin immunoreactive connective tissue mast cells [CTMCs], showing strong metachromasia with the Wright stain, were located together with the MMCs in the submucosa of the stomach. In most of the gut regions of the control group, the majority of the MMCs did not show any serotonin immunoreactivities and only a few MMCs showed weak serotonin immunoreactivities. After stimulation of the vagus nerves, the number and the immnu- noreactivities of the serotonin immunoreactive MMCs dramatically increased in all gut regions observed, especially in the small intestines. In the samples treated with the electron microscopic immnunocytochemical methods, hardly any serotonin immunoreactivities were detected in the MMCs of the control group. However, the serotonin imrnunoreactivities of the MMCs were significantly increased after vagus nerve stimulation. The serotonin immnunoreactive products were localized, following vagal stimulation, both in the peripheral matrix of the granules and in the cytoplasm. Also, it was confirmed ultrastructurally that the Golgi complexes were expanded in the MMCs of the vagal stimulation group. The above results suggest that vagus nerve stimulation may activate serotonin biosynthesis in MMCs.

This study was undertaken to investigate the ultrastructure of the neurons, neuroglial cells and capillaries in the area postrema[AP] of the Oriental discolured bat, Vespertilio superans. The AP of the bat was a single midline structure at the most caudal portion of the fourth ventricle. Most neurons in the AP were small cells, but their ultrastructure were similar to the typical neurons located elsewhere in the central nervous system. Astroglial cells and oligodendrocytes were also observed and showed their typical ultrastructure. Ultrastructural features of neurons, astroglial cells and oligodendrocytes were not changed during hibernating cycles. However, microglial cells were only found in the hibernating AP ; these cells were located in the parenchyma and near the blood vessels of the AP. Since the microglial cytoplasm was filled with phagocytotic inclusions, the nuclei of the these cells were eccentrically located. Phagocytotic cytoplasmic inclusions were shown to be composed of a dense irregular peripheral region and the pale round central region. A Large vacant space was often found in the electron lucent central region. Continuous and fenestrated capillaries surrounded by pericytes were found in the bat`s AP. Especially, Phagocytotic inclusions were found in the pericyte cytoplasm of the hibernating AP, and this result supports suggestion that pericytes might be phagocytotic cells. On the basis of the distributions of phagocytotic tells[pericytes and microglial cell], ultrastructure of these cells, morphology of their cytoplasmic inclusions, and the appearance of phagocytotic activity of the pericytes during the hibernating stage when microglial cells were observed, it can be concluded that pericytes may also participates in the formation of rrlicroglial cells. Tanycytes were also found in the bat AP.

An evaluation of axillary block in 803 clinical cases, during the period from January 1974 to June 1979, was made. Satisfactory results were obtained in 756 out of 803 blocks (94. 2%) with the axillary perivascular technique. The authors feetl that the axillary perivascular technique in which a relatively large volume(40~50ml) of anesthetic solution was administered into the perivasculsr space of the axilla was simple, convenient and had no serious complications compared to the supra-or subclavian perivascular technique and interscalene block for a diagnosis and treatment of upper extremities.

We performed a reoperation of failed tricuspid mechanical valve in a 63-year-old female patient because the overgrown endothelial pannus had entrapped the prosthetic leaflets. Four years ago, the patient underwent mitral and tricuspid valve replacements with 31 and 33 mm Carbomedics, respectively. The patient showed symptoms of neck vein distention, abdominal distention and peripheral edema. The chest film, echocardiography and cineangiography confirmed the diagnosis of tricuspid valve. During the operation, we found the entrapped leaflets of the tricuspid valve in a partially closed state and the endothelial pannus had overgrown into the leaflets. Carpentier-Edward bovine pericardial valve was inserted and the patient was discharged with no significant events.

OBJECTIVES: Many recent studies of relationship between geriatric depression and changes in brain have examined the structural abnormalities in hippocampus. Using MRI, the hippocampal volumes of patients with major depression were measured and compared with control subjects for research of above relationship. METHOD: Fourteen patients (early-onset five, late-onset nine) with major depressive disorder based on DSM-IV and fourteen age-matched normal controls are included. Applying semiautomated computer program to MRI, we measured and compared the hippocampal volumes in two groups. Moreover we identified the laterality and the correlation of the volumes with age of onset, duration of education, numbers of psychiatric admission, duration of illness, MMSE scores at admission, and severity of depression. RESULT: No significant difference was observed between the hippocampal volumes of patients with major depressive disorder and those of control subjects. A significant correlation in patients was observed between duration of illness and left hippocampal volume to cerebral volume ratio. In early-onset depressed patients, left hippocampal volume was larger than in late-onset depressed patients and the positive correlation was observed between MMSE scores at admission and left hippocampal volume to cerebral volume ratio. In late-onset depressed patients, there was the negative correlation between numbers of psychiatric admission and MMSE scores at admission as well as and between cerebral volume and age of onset. CONCLUSION: Our study indicated no change in the volume of hippocampus among geriatric major depressive patients. So we suggest that more extensive and systematic studies for structural abnormality of hippocampus will be required.

To evaluate trends, if any, anesthetic experiences of 10,000 cases in the total performed at the department of Anesthesiology, Han Kang Sung Shim Hospital, Choong Ang University, School of Medicine from Dec. 197I through Nov. 1976 were analyzed statistically according to anesthetic method, age, sex, department, anesthetic agent, anesthetic duration, physical status and cause of death. The results are as follows; 1. About forty-five percent of all surgical patients were emergency cases. 2. The spinal and regional blocks tended to increase compared with inhalation anesthesia. 3. The patients under 1 year and over 60-years of age also tended to increase. 4. In almost all cases, post-operative and post-anesthetic cause of death was due to the severity of preexisting disease itself and overall death rate of surgical patients who received anesthesia was 0.16% 5. Through this statistical study, we can perform anesthesia with more safety and ease, and also eliminate post-operative and post-anesthetic complications, with further study of new agents and techniques.
