본 실험은 부교감신경의 하나인 미주신경이 난소를 지배하는 신경으로 관여하고 있는지를 pseudora. bies 바이러스를 이용하여 난소신경로와 난소주사후 미주신경정단을 통하여 조사한 연구 보고이다. 이를 위하여 Sprague Dawley계 암흰쥐를 대상으로 pseudorabies 바이러스를 난소에 주사한 무리와 난소 주사후 미주신경을 정단한 우리에서 뇌를 적출하여 pseudorabies 바이러스에 대한 연역조직화학 염색을 시행하여 비교하였다. 본 실험결과 미주신경 중추신경로내의 상위신경핵들이 pseudorabies 바이러스에 대하여 양성반응이 줄어들었거나 관창되지 않는 차이를 보였다 즉 적색핵, 종말판혈관기판, 줄무늬체, 침상핵과 이마엽겉질은 부분적으호 난소의 미주신경로에 관여하고 있으며 미주신경동쭉핵, 고립로핵, 최후영역, 청색반정, 팔옆핵, 코리케퓨즈핵 , 흑색질 및 시각교차위핵은 양성반응이 관찰되지 않아 미주신경으로 투사하는 부교감신경핵으로 조사되었다.

The study on the nerve cells in the subesophageal ganglion of adult cabbage butterfly (Pi-eris rapae L.) was performed to observe their structural characteristics. The subesophageal ganglion which had been associated to rear part of brain in the process of metamorphosis of larva to pupa was consisted of neuropile in the central region and nerve cell bodies in the rind. The nerve cell bodies were divided into three types on basis of their shapes, sizes and presence of neurosecretory granules, etc. In type I nerve cells the sizes of their cell bodies were 9.5 to 14.5μm in diameter and those of their nuclei were 7.0 to 12.0μm. The type I nerve cells which were the most typical neurons of brain nerve cells from cabbage butterflies had round or ellipsoid shapes. The type Ⅱ nerve cells had a variety of shapes, i.e., round, ellipsoid or triangle, and their sizes were 14.5 tp 20.0μm in diameter. The type Ⅱ nerve cells which included a number of neurosecretory granules were considered neurosecretory cells. The type Ⅲ nerve cells had the smallest sizes of approximately 4.5μm in diameter and their nuclei were about 2.5μm. These cells had no secretory granules in their cell bodies.

Morphological studies on larval hemocytes of varioius insects were performed in two ways of research. Ⅰ. Finestructures. An electron microscopical study on hemocytes of last instar larvae of 12 species of Lepidoptera was performed to observe cell types, structrues, raions, relationships and their origins. The results are as follows; 1) Prohemocytes are the smallest round cells with large numlesus, poorly developed cytoplasmic organelles and lower composition ratio, accounting for less than 5% of all cell types. Little remarked differences were revealed among prohemocytes of varous insects and they are thought to be the origins of other cell types. 2) Palsmatocytes are relatively large cells with higher composition ration, accounting for about 40%. They could be subdivided into two forms, oval and spindle. Oval cells are rich in cytoplasmic projections and organelles. But the spindle cells include few of them, while nearly all of the spindle cells possess some microtubules as their cytoskeletons. Some marked difference were revealed among different insects. The most exceptional structure was the fibrous bundles located in both nucleus and cytoplasm in Sericinus telamon Donovan. 3) Granular cells are characterized by various granules in cytoplasm, and by higher composition ration, accounting for about 50% of all numbers. They could be subdivided into three forms, oval, round and spindle with fully developed cytoplasmic organelles and Projections. Cellular fractions were often noticed to be enclosed by granular cells, indicating some activities of phagocytosis. Granular cells are the most pleomo rphous of all cell types, and the most exceptional structures are the bundles of microfibrils in Phalerodonta manleyi Leech. 4) Adipohemocyte were found only in Plodia interpunctella Hubner. They are somewhat oval with few cytoplamic projections and less developed organelles. Some granular cells were found to accumulate lipid droplets into the cytoplasm by trapping floating lipid droplets, adn the adipohemocytes are believed to be originated from formers. 5) Sperule cells were found nearly in all specimens and characterized by sperules composed of flocculent materials. They are round or oval with few cytoplasmic organelles. The most conspicuous spherulesof all sperule cells were radial arrangement of sperules in Adristyrannus amurensis Staudinger and presence of the specific granules in Mamestra illoba Butler. Young sperule cells resembled the granular cells and it is possible that they originate from granular cells. 6) Oenocytoids are large cells and were found nearly in all specimens. They could be subdivided into 3 types according to their inclusions, such as microfibrils, microtubules and none of them. Young Oenocytoids resemble the giant plasmatocytes, perhaps in dicating to be originated from the latters. Ⅱ. Composition ratios of cell types from mid 5-instar to late prepupa. Composition ratios of cell types were investigated in phalerodonta manley; Leech and could be summarized as follows; 1) Prohemocytes disappeared from the stage of early prepupa. 2) Plasmatocytes increased in number at mid stages of each inster and decreased nearing to pupal stage. 3) Granular cells reached peak at early prepupal stage. 4) Adipohemocytes heavily increased at late prepupal stage. 5) Sperule cells increased at late stage of each instar and reached peak at late prepupal stage. 6) Oenocytoids increased at late stage of each instar and reached peak at early prepupal stage.

본 실험은 부교감신경의 하나인 미주신경이 난소를 지배하는 신경으로 관여하고 있는지를 pseudorabies 바이러스를 이용하여 난소신경로와 난소주사후 미주신경절단을 통하여 조사한 연구 보고이다. 이를 위하여 Sprague Dawley계 암흰쥐를 대상으로 pseudorabies 바이러스를 난소에 주사한 무리와 난소 주사후 미주신경을 절단한 무리에서 뇌를 적출하여 pseudorabies 바이러스에 대한 면역조직화학 염색을 시행하여 비교하였다. 본 실험결과 미주신경 중추신경로내의 상위신경핵들이 pseudorabied 바이러스에 대하여 양성반응이 줄어들었거나 관찰되지 않는 차이를 보였다. 즉 적색핵, 종말판혈관기관, 줄무늬체, 침상핵과 이마엽겉질은 부분적으로 난소의 미주신경로에 관여하고 있으며 미주신경등쪽핵, 고립로핵, 최후영역, 청색반점, 팔옆핵, 코리케퓨즈핵, 흑색질 및 시각교차위핵은 양성반응이 관찰되지 않아 미주신경으로 투사하는 부교감신경핵으로 조사되었다. The mammalian ovary has been known as receiving its innervation by sympathetic and sensory neurons of the peripheral nervous system from the brain. Recently, there were several functional reports that the vagus nerves were also regulating the ovarian function, but the vagus nerve had not been identified by clear morphological evidence. A viral transneuronal tracing technique has been used to demonstrate the morphological evidence for the central vagal involvement in ovarian innervation in brain areas. Bartha strain of pseudorabies virus injection was made into the ovary of Sprague Dawley rats. In experimental group, the vagus nerve of the same injection side was removed right after ovarian injection. At five days after initial injection, all the rats were sacrificed and brains were processed for immunohistochemistry. Several central nuclei including hypothalamic paraventricular nucleus showed strong bilateral positive labelings after unilateral injection in control rats, but the positive labelings were disappeared or decreased in several hypothalamic nuclei and nuclei of the vagus nerve. I n conclusion, these results provide the morphological evidence that vagus nerve has neural connection to ovary and by which the central nervous system may maintains the state of ovulation and reproduction as a possible parasympathetic routes in mammals.
