This experimental studies was to investigate the location of PNS and CNS labeled neurons following injection of 2% WGA-HRP and pseudorabies virus (PRY), Bartha strain, into the ductus deferens of rats. After survival times 4-5 days following injection of 2% WGA-HRP and PRV, the rats were perfused, and their brain, spinal cord, sympathetic ganglia and spinal ganglia were frozen sectioned ($30{\mu}m$). These sections were stained by HRP histochemical and PRY inummohistochemical staining methods, and observed with light microscope. The results were as follows ; 1. The location of sympathetic ganglia projecting to the ductus deferens were observed in pelvic ganglion, inferior mesenteric ganglion and L1-6 lwnbar sympathetic ganglia. 2. The location of spinal ganglia projecting to the ductus deferens were observed in T13-L6 spinal ganglia. 3. The PRY labeled neurons projecting to the ductus deferens were observed in lateral spinal nucleus, lamina I, II and X of cervical segments. In thoracic segments, PRY labeled neurons were observed in dorsomedial part of lamina I, II and III, and dorsolateral part of lamina IV and V. Densely labeled neurons were observed in intermediolateral nucleus. In first lumbar segment, labeled neurons were observed in intermediolateral nucleus and dorsal commisural nucleus. In sixth lumbar segment and sacral segments, dense labeled neurons were observed in sacral parasympathetic nuc., lamina IX and X. 4. In the medulla oblongata, PRV labeled neurons projecting to the ductus deferens were observed in the trigeminal spinal nuc., A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular nuc., rostroventrolateral reticular nuc., area postrema, nuc. tractus solitarius, raphe obscurus nuc., raphe pallidus nuc., raphe magnus nuc., parapyramidal nuc., lateral reticular nuc., gigantocellular reticular nuc.. 5. In the pons, PRV labeled neurons projecting to the ductus deferens were ohserved in parabrachial nuc., Kolliker-Fuse nuc., locus cooruleus, subcooruleus nuc. and AS noradrenalin cells. 6. In midbrain, PRV labeled neurons projecting to the ductus deferens were observed in periaqueductal gray substance, substantia nigra and dorsal raphe nuc.. 7. In the diencephalon, PRV labeled neurons projecting to the ductus deferens were observed in paraventricular hypahalamic nuc., lateral hypothalamic nuc., retrochiasmatic nuc. and ventromedial hypothalamic nuc.. 8. In cerebrum, PRV labeled neurons projecting to the ductus deferens were observed in area 1 of parietal cortex. These results suggest that WGA-HRP labeled neurons of the spinal cord projecting to the rat ductus deferens might be the first-order neurons related to the viscero-somatic sensory and sympathetic postganglionic neurons, and PRV labeled neurons of the brain and spinal cord may be the second and third-order neurons response to the movement of smooth muscles in ductus deferens. These PRV labeled neurons may be central autonomic center related to the integration and modulation of reflex control linked to the sensory and motor system monitaing the internal environment. These observations provide evidence for previously unknown projections from ductus deferens to spinal cord and brain which may be play an important neuroanatornical basic evidence in the regulation of ductus deferens function.

간추림 토끼 고양이 돼지 및 사람의 latex 심방조형을 제작하여 심방내강의 형태를 관찰한 바 다음과 같은 결과를 얻었다. 동물에 따라 차이는 있으나 대체로 심방귀 조형은 여러 개의 가지 모양의 구조로 되여 있다. 고유심방의 조형은 한 개의 둥근 latex덩어리로 되어 있었으며 latex 덩어리로부터 나온 가지들은 2~3차에 걸쳐 다시 작은 가지로 나누어져 있고 가지의 표면에는 주름이 잘 발달되어 있으며 맨 끝 가지는 손가락과 같은 몇 개의 구조로 갈라져 끝났다. 동물에 따라 오른쪽과 왼쪽의 심방귀의 조형은 일정한 모양의 구조로 되어있으며 왼쪽은 오른쪽의 것보다 길고 잘 구분되는 가지 모양의 구조를 갖고 있어서 오른쪽과는 차이가 있었다.

신경독성물질인 5, 7-dihydroxytryptamine (5, 7-DHT)이 중추신경계통내 serotonin 신경세포에 미치는 영향과 이에 따른 신경아교세포들의 반응을 형태학적으로 규명하고자 본 연구를 시행하였다. 흰쥐의 가쪽뇌실에 5, 7-DHT(200μg)를 투여한 후면역세포화학적 염색을 시행한 후 광학 및 전자현미경하에서 등쪽솔기핵내 serotonin 신경세포에 초래되는 퇴행성변화와 주위 신경아교세포들의 반응양상 등을 경시적으로 (1, 3, 5, 10 및 20일) 관찰하였던 바 아래와 같은 결과를 얻었다. 흰쥐 등쪽솔기핵내 5, 7-DHT의 세포독성에 반응을 보인 신경아교세포로는 미세아교세포와 별아교세포였으며, 이들 세포 들의 반응양상은 매우 특징적이었으며, 상당한 차이를 보였으며, 전반적으로 미세아교세포가 별아교세포에 비해 빠른 변화소견을 보였다. 즉, 미세아교세포의 경우 실험 3일군 및 5일군에서 이미 그 수의 증가와 함께 활발한 포식작용을 보였던 반면, 별아교세포는 후기 실험군인 10일군 및 20일군에 이르러서야 세포질의 비대 및 수적 증식을 통하여 손상된 신경조직을 보상할 뿐 아니라 밀집된 미세아교세포들을 분산시키는 소견이 관찰되었다. 그러나 희소돌기아교세포는 본 연구의 전 실험군을 통하여 특별한 변화소견이 관찰되지 않았다. 이상의 결과로 부터 5, 7-DHT가 흰쥐 등쪽솔기핵내 신경세포에 강한 세포독성을 유발하며, 이에 따른 주위 신경아교세 포들 특히 미세아교세포와 별아교세포는 시간경과에 따라 매우 다양한 반응양상을 보인다는 사실을 알게 되었다 This study was designed to clarify the cytotoxic effects of 5, 7-dihydroxytryptamine (5, 7-DHT) on the serotonergic neurons in the dorsal raphe nucleus, and to investigate the glial reaction during the neurodegenerative changes by light and electron microscopy. Adult male rats (Sprague-Dawley strain) weighing from 250 g to 350 g each were used as experimental animal. 5, 7-DHT(200 μg dissolved in 0.9% NaCl) was injected into the lateral ventricle of the rat brain with the Hamiton syringe fixed on stereotaxic apparatus. The control rats were given with the similar volume of 0.9% NaCl. The rats were sacrified on the 1st, 3rd, 5th, 10th and 20th day after the injection of 5, 7-DHT. The results were as follows : Glial reactions induced by 5, 7-DHT were also observed in DRN. In early experimental stage, microglial reactions prevailed, whereas astroglial reactions were prevailing in later stage. In addition, microglial cells phagocytosed and removed the degenerated cells. However, astrocytes in DRN did not show phagocytotic activities such as microglial cells. Based on the results, author thought that 5, 7-DHT act as a specific neurotoxin to serotonergic neurons in DRN, and induces severe neurodegenerative changes. The glial reactions in DRN are activated during the neurodegerative changes, and show characteristic patterns of glial reactions.

To investigate the elects on the administration of Opae-san in rats. Opae-san (500mg/day) and omeprazole(10mg/day) were administration with stomach tube for 4 weeks and 8 weeks. This experiment were investigated numerical change of immunoreactive cells of gastric, histamine and somatostatin in rat stomach mucosa by the immunohistochemical method. The results were as follows : 1. In Opae-san administration group for 4 weeks, the number of gastric immunoreactive cells were increased in one and a half times than that of control group. In omeprazole administration group for 4 weeks, the number of gastric immunoreactive cells were increased in four times than that of control group. In Opae-san administration group for 8 weeks, the number of gastric immunoreactive cells were increased four times than that of control group. In omeprazole administration group for 8 weeks, the number of gastrin immunoreactive cells were increased in six times than that of control group. 2. In Opae-san administration group for 4 weeks, the number of histamine immunoreactive cells were increased in two times than that of control group. In omeprazole administration group for 4 weeks, the number of histamine immunoreactive cells were increased in six times than that of control group. In Opae-san administration group for 8 weeks, the number of histamine immunoreactive cells were increased three times than that of control group. In omeprazole administration group for 8 week, the number of histamine immunoreactive cells were increased in seven times than that of control group. These results suggest that Opae-san extracts inhibit the secretion of gastric acid and this extract use to therapeutic herb of gastric disorders related to the hyperacidity and gastric ulcer.
