  • To predict the influence of carbon monoxide poisonining on cerebral energy metabolism, rats were exposed to 5000 ppm environment for 30 minutes. Carboxyhemoglobin (HBCO) saturation rate in this condition was 72% equally in male and female rats. Cerebral cortex in the rats showed lower level of ATP, glucose, creatine phosphate and higher level of lactate, pyruvate by anaerobic glycolysis. As for the levels of ATP, creatine phsphate and glucose, the cerebral cortex contents of them were larger in female rats of estrus than in male rats, whereas there was no difference between sexes in the levels of pyruvate and lactate. According to time passage from CO intoxication, the mode of changes in cerebral energy metabolite contents was similar in both sexes.

  • This study aims to define the relationship between brain and heart through several literatures about oriental medicine and the conclusions are as follows. Heart in oriental medicine is called as Sinmyeongjishim(神明之心) which has a close connection with Mind, Consciousness, Emotion, and Physiological instinct of Drain in modern medicine. According to Oriental medicine, Brain stores Wonsin(元神) as Heart stores mind(神). Heart is where mind rests whereas Brain is where mind reveals. The external evidences that prove the relationship of Heart and Mind are as follows: First, with ears, eyes, mouth, and nose the subject of cognition is recognized as Sinmyeongjishim(神明之心). Second, Bulin(不仁), which means decreased movement power and sensibility of limbs, proves that Sinmyeongjishim(神明之心) is involved with movement power and sensibility of limbs. The physiological evidences that prove the relationship of Heart and Mind are as follows; First, Heart as the operation of Sinmyeongjishim(神明之心) manages language. Second, Heart is related with Tongue. Third, Heart is linked to Ears through the ear hole. Fourth, Heart is a store of Mind. Fifth, the five viscera control emotional and psychological activities. The pathological evidence of the relationship of Heart and Mind is that the symptoms of heart disease which are related to Sinmyeongjishim(神明之心) are also related to the functions of Brain. Though Brain has a close connection with Heart in oriental medicine, it is recognized that there are distinctive symptoms of disease of Brain and Hyeolyookjishim(血肉之心) respectively. The relationship of Heart and Brain has been researched in this study, even though there are not enough written materials about oriental medicine. But the fact that the majority of Heart operation is deeply connected with Brain activities cannot be denied. Therefore the research of Heart should be done as well as Brain in the clinical study of Brain.

  • 웅성-마우스의 고환을 diethyl ether마취하에서 제거하고, 수종의 steroid 홀몬을 각각 매일 1회씩 4일간 피하주사한 다음 날의 오전 11-12 시에 뇌, 신장, 간장 및 소장의 polyamine을 검량하여 다음의 성적을 얻었다. 1. 고환절제-마우스(CM)에서, 소장 putrescine(PT)는 비고환절제-마우스(UCM)에 비하여 유의한 저하를 보였으나, 간 및 소장의 spermine(SM)은 오히려 유의하게 증가되었다. 2. Hydrocortisone 50 mg/kg는 UCM의 소장 PT는 현저히 증가시켰으나, CM의 뇌 PT 함량은 오히려 감소시켰다. 3. Estradiol 5 mg/kg는 UCM의 간 PT 함량을 현저히 증가시켰으며, CM에서는 간 PT 뿐만 아니라 신장의 전 polyamin 함량-증가와 아울러, 다소의 뇌 및 소장 PT-증가를 유도하였다. 4. Dehydroepiandrosterone 250 mg/kg(DHEA)와 testosterone 5 mg/kg(TS)는 UCM의 경우 신장 PT 함량만 유의하게 증가시켰으나, CM에서는 신장의 PT, spermidine(SD), 및 SM 모두를 더욱 현저히 증가시켰고, 아울러 DHEA는 간 SM의 감소를, TS는 뇌 SM의 유의한 증가를 유도하였다. 이상의 결과로 미루어 볼때, 간 및 소장의 polyamine대사-특히 PT함량의 변동은 각각 E2 및 HC에 의하여 보다 특이적으로 조절되고, 신장의 polyamine 대사는 성steroid들에 의하여 다소 비특이적인 조절을 받는 것으로 생각되며, 고환절제-마우스에서 나타나는 HC에 의한 뇌의 전potyamine감소 및 성steroid들에 의한 신장의 전polyamine증가의 발현기전에 대한 연구가 있어야 할 것으로 사료된다.

  • Whole brain irradiation is one mode in the treatment of brain cancer and brain metastasis, but it might cause brain injury such as brain necrosis. It has been studied whether the dose distribution could be a cause of brain injury. The dose distribution in whole brain irradiated by Co-60 beam has been measured by means of calibrated TLD chips inserted in the brain of Humanoid phantom. The following results were obtained. 1. Dose distribution on each transverse section of the brain was uniform. 2. On the midsagital plane of the brain, the dose was highest in upper portion and lowest in lower portion, varying 8 from 104% to 90%. 3. When the radiation field includes free space of 2cm or more width out of the head, the dose distribution in the whole brain is almost independent of the field width. 4. It is important to determine adequate shielding area and to set shielding block exactly in repetition of treatment.

  • The present study is concerned with the demonstration of the relationship between the behavior and the brain concentration of noradrenaline resulted from pretreatment of amphetamine in isolated or aggregated rats. The experimental subjects were rats weighing from 120g to 200g housed 1, 2, and 6 in a cage. Analeptic activity of amphetamine was measured by determining the sleeping time induced by pentobarbital sod. The noradrenaline content in brain was determined with Aminco-Bowmann's spectro-photofluorometer by Lee's modification of Shore and Olin method. Results: 1) The analeptic activity of amphetamine on the sleeping time induced by pentobarbital sod. was more increased in the grouped rats than in isolated animal. 2) In being isolated and grouped rats, the sleeping time induced pentobarital sod, was markedly prolonged by pretreatment of amphetamine. 3) Means of housing rats, e.g., isolation or aggregation did not seem to affect the brain noradrenaline depleting action. 4) Repeated daily parenteral administration of amphetamine sulfate for a period 1 to 3 weeks resulted in decrement of brain noradrenaline concentration in being isolated and grouped rats. 5) The prolongation of sleeping time of the isolated or aggregated rats, when pretreated with amphetamine, compared with that of stock rats, seems to be attributable rather to the means of housing than the variation of the noradrenaline caused by amphetamine.

  • Relationship between hypertension and monoamine oxidase (MAO) activity in rat brain and the change of this relationship by presynaptic ${\alpha}-receptor$ agonist were studied. Animals were divided into three groups. Group I was composed of normotensive Sprague-Dawley rats (NR), group II of spontaneously hypertensive rats (SHR) and group III of acquired hypertensive rats induced by deoxycorticosterone acetate (DOCA) and NaCl treatment. Clonidine, a presynaptic ${\alpha}-receptor$ agonist, was administered to groups II and III. Blood pressures and MAO activities were measured in each group. MAO activities in the brain of SHR were lower than those of NR. Animals in group II received clonidine which lowered blood pressures but did not change MAO activities in the brain. DOCA and NaCl induced hypertension 21 days after these treatments in group III and did not cause any changes in brain MAO activity. Clonidine lowered blood pressures of group III but did not change MAO activities. The data from the present study suggest that abnormaly low MAO activities in SHR brain may be one of the underlying factors for the susceptibility to hypertension and that the decrease in noradrenergic neuronal activities through presynaptic ${\alpha}-receptor$ activation by clonidine may not be related to the changes of brain MAO activities.

  • The effect of dietary condition on the acethylcholine and chotinesterase activity in the brain was observed. Rats weighting $120{\sim}130\;gm$ was fed on diets deprived of protein, carbohydrate and lipid, respectively. Experimental terms was devided into 3, 7 and 15 days. The results are summarized as follows: 1. The lipid free diet makes greater contribution to the gain of body weight than the carbohydrate free and protein free diet. 2. The acethylcholine in the protein free diet group is reduced after 7 days and that in the carbohydrate free diet, after 3 days. 3. The cholinesterase activity shows continuing decrease after 3 days by protein free diet, and the other diet groups appear temporal decrease at 7 days and increase, at 15 days. 4. The relation of acethylcholine, and cholinesterase is similar to each other except that of the carbohydrate diet. From the above results, the conclusions are obtained that the protein free diet makes the acethylcholine and cholinesterase activity lower, and the carbohydrate free diet, acethylcholine lower.
