Tetrodotoxin is a neurotoxin produced by about 90 species of puffer fish and causes paralysis of central nervous system and peripheral nerves by blocking the movement of all monovalent cation. Ingestion of tetrodotoxin produces clinical manifestations such as paresthesias(within 10-45 min), vomiting, lightheadedness, salivation, muscle twitching, dysphagia, difficulty in speaking, convulsion and death that expressed by cardiopulmonary arrest with loss of brain stem reflex sometimes. Tetrodotoxin prevents or delays ischemia induced neuronal death by way of following 3 mechanisms. Firstly, it reduces the energy demand of the brain tissues. Secondly, it delays or even prevents anoxic depolarization. Finally, it deminishes ischemia induced cell swelling and cerebral edema. We report a case of puffer fish poisoning which presented with cardiopulmonary arrest and loss of brain stem reflex, but completely recovered by aggressive cardiopulmonary resuscitation.

It is necessary to develop and supply special equipment suitable for reclaimed area agriculture in accordance with the progress of agricultural mechanization. But it is more worth while to consider how to effectively use the machinery such as tractors and power tillers which have already been supplied for reclaimed area agriculture. Thus we have carried out an experiment to study the working rate slope and safety of the machine frame when this machinery is used in the area. 1. Plowing working rate of bottom plough was 35.8 minute per 10 ares on the 6 slope and 47.6 minutes on the 10 slope. These working rates were lower. than those of flat land by 44% and 33% respectively. Working rates of disc harrow on the 6 and 10 slopes were 55-76% of the working rates at the flat land. In case of power tiller, working rates on slopes were about 35-58% of those an float land. 2. Harrowing working rates on the Rotavator was 18.5 minutes per 10 ares on the 6 slope and 22.01 minutes on the 10 slope. 3. The working rate of making catch canals was 18.8 minutes per 50m of catch canal when a disc harrow was used on the 6 slope. 4. The real slope of the tractor body in the plowing operation in accordence with the different land slope is almost the same when plowing by bottom plough or plowing by disc plow. However, considering the overturn of tractor on the steep slope and the proliferation of roots it is better to plow by disc plough than by bottom plough. 5. During ploughing operation in the sloping area, the inclination of the tractor with bottom plough was more than that of the tractor equipped with disc harrow and for power tiller it was more with rubber tire than with cage wheel. 6. It was found that the steeper the slope is, the more was the slip of the tractor, or power tiller and the slip to the contour direction was more in conparition to the slip occured to the direction of the slope.

This research was performed to optimize the anaerobic pretreatment of slurry type swine wastewater for the subsequent nitrogen and phophorus removal. Step-wise increases in Organic Loading Rate(OLR) and decreases in Hydraulic Retention Time(HRT) were utilized in Upflow Anaerobic Fixed Bed(AFB) reactor at mesophilic temperature(35℃). The maximum methane prodution rates of 1.16 v/v-d was observed at an HRT of 12 hours. TCOD removal efficiency of 75% at an HRT of 2 days and 41% at an HRT of 12 hours were obtained respectively. It is likely that the influent COD concentration of 3,000 mg/L for the subsequent biological nutrient removal system could be supplied from the anaerobic pretreatments operated at an HRT of 12 hours(OLR 12g CODL-day). During AFB operation alkalinity showed 800- 1,500mg/L as CaCO_(3) at all HRTs. It could play an important role for compensating pH drop caused by nitrification. The COD/TKN ratio of 6-14 at all HRTs, COD/TP ratio of 30-50 at an HRT of 1 day and proper buffering capacity and pH of the effluent from the anaerobic fixed bed could be adequate substrate condition in the following nitrogen and phosphorus removal. In conclusion, when AFB was operated at an HRT less than 1 day, the system could be optimized to reach an efficient anaerobic pretreatment for swine wastewater and the subsequent biological nutrient removal.

In the literature study on the cerebral palsy, the results were as follows : 1.Cerebral palsy is defined as a disorder of movement and posture due to a defect or lesion of the immature brain. For practical purposes it is useful to exclude from cerebral palsy those disorders of posture and movement which are of short duration, due to a progressive disease, due solely to mental deficiency. 2.Cerebral Palsy is classified with quadriplegia, diplegia, hemi plegia, triplegia, and monoplegia or spastic CP, athetoid CP, ataxic CP, and combined classifications. 3.Causes of Cerebral Palsy is any damage with prenatal, natal and postnatal causes. 4.Management consists of helping the child achieve maximum potential in growth and development. This should be started as early as possible with identification of the very young child who may have a developmental disorder. Certain medications, surgery, and braces may be used to improve nerve and muscle coordination and prevent dysfunction. 5.The aim of treatment is to encourage children and adults to learn to be as independent as possible. Some children and adults who have midl cerebral palsy will have no problems in achieving independence 6.Oji(五遲),Oyeon(五軟) and Okyeong(五硬) have the simmiar concepts with the cerebral palsy. 7.Oji(五遲) Oyeon(五軟) and Okyeong(五硬) are caused by seoncheon-pumbu-bujok(先天稟賦不足) and related with gan(肝), bi(脾) and sin(腎). 8.The treatment is achieved by the method of bogansin(補肝腎), ganggeungol(强筋骨) and bojungikki(補中益氣).

Lupus vulgaris, which is a progressive form of postprimary tuberculosis in patients with a moderate to high degree of immunity and tuberculin sensitivity, is the most common, most serious, and most variable type of cutaneous and mucous membrane tuberculosis. Domonstration of M.tuberculosis directly or in culture in some of these eruptions can be difficult. It is essential to demonstrate the presence of M.tuberculosis in a clinical sample for a definitive diagnosis of tuberculosis. With the discovery of the polymerase chain reaction (PCR), the DNA diagnostic approach for infection has developed in a short period. With the dual purpose of definitive and rapid diagnosis of tuberculosis, this study examined the usefulness of a nested PCR for detection of M. turberculosis. Compared with a single-step PCR, the two-step PCR was able to enhance sensitivity approximately 1,000-fold on the basis of bacterial counts and DNA quantity. We concluded that two-step nested PCR appeared to be the most useful PCR protocol for early and sensitive diagnostic method detecting M.tuberculosis in acid-fast stain negative specimens.
