The author experienced a schizophrenic patient who had one episode of spontanous convulsive attack which was followed by symptom relief. A 33 yrs old male schizophrenic patient showed vivid auditory hallucination, grandiose delusion, persecutory idea, unrealistic thinking with aggressive and suicidal tendency for the past 3 years. These symptoms were relieved following this episode of spontaneous seizure attack.

Vegetable transplanting operation has been wholly depended on human labor that needs 18.4 hrs per 10 acres in Korea. Since periods of vegetable transplanting operations are limited, their mechanization has been strongly demanded. This study was conducted to develop a transplanting device that was the core technology for vegetable transplanter. In order to find out transplanting track and velocity of transplanting device, a kinematic analysis software was employed. Evaluation of prototype was carried out in the circular soil bin with high speed camera. Rotary type transplanting device produced an elliptic loci when two links of different lengths were moving to the opposite direction. The length of two links was 75 mm and 44 mm, respectively. Maximum displacement of rotary type transplanting device was 238 mm. It seemed that the transplanting elliptic loci of transplanting device were identical between the simulation output generated by kinematic analysis software and the circular soil bin test result with a high speed camera. The rotary type transplanting device can be suitable for transplanting short height vegetable, less than 20 cm length vegetables such as Chinese cabbage and cabbage, etc.
PC12세포에서 Reserpine에 의한 Preproenkephalin 유전자 발현의 조절
박석호,임동윤,최철희,김상훈,박상학,김학렬 조선대학교 1994 The Medical Journal of Chosun University Vol.19 No.1
In cultured PCl2 celIs, prepronkephalin gene expression was studied by measuring preproenkephalin mRNA levels as well as enkephalin content after the treatment of reserpine. Reserpine(0.5 uM) elicited and increased enkephalin peptide levels within 6-24 hrs, which was not inhibited by cycloheximide(2ug /ml), a protein synthesis inhibitor. In addition, reserpine-induced increase of enkephalin was not inhinited by dactinomycin(5ug / ml), which was found to decrease preproenkephalin mRNA. When preproenkephalin mRNA was measured by Northern blot hybridization with cDNA probe, reserpine elicited a slightly increased preproenkephalin mRNA in PCl2 cells as well as in the rat adrenal glands. From the present experimental data it is thought that reserpine-induced enhancement of cellular enkephalin content in cultured PCl2 cells may be mediated through the post translational processing along with a slightly increased transcription.

The authors report a case of hyperventilation syndrome shown in a male patient of 17 years. In relation to emotional stresses, he has suffered from overbreathing followed by tingling sensation and tetany of both upper and lower extremities and precordial pain. The patient was remitted completely after 30 days of treatment in neuropsychiatric department since admission. So clinical and psychodynamic aspects were discussed, and several literatures were reviewed. (The authers wish to thank prof. Yong Sub Ohm, M.D.)
