Histochemical experiment was carry out respectively to confirm the properties of the salis (Achatina fulica and Incilaria fruhstorferi). SDS-PAGE was carried out to compare and invertigate the distribution aspects of protein patterns between the two species. Five types(A, B, F, H and I)of gland cells with four neutral mucopolysaccharide cells and one acid mucopolysaccharide cells and one acid mucopolysaccharide cell were observed in acinous of Achatina fulica, while six types were observed in acinous of Incilaria fruhstorferi: ond acid mucopolysaccharide cell(type-A) and four neutral mucopolysaccharide cells(type-B, C, D and F) and one cell that acid mucopolysaccharide is only mimbrane that surrounded granule(type-E). The results are follows:The thpe-A fland cell is commonly observed between the two species. The type-A gland cell in Achatina fulica possesses a nucleus with a developed heterdchromatin, and the cytoplasm was filled with round granules. The granules were surrounded with an uncertain boundary mimbrane and confirmed with neutral mucopolysaccharides, but is confirmed acid mucopolysaccharide in Incilaria fruhstorferi.The type-B gland cell is obwerved in the two species, too. The type-B gland cell in Achatina fulica was round shaped, and included an evenly alrge nucleus. The uncleoplasm included granules that were confirmed in the neutral mucopolysaccharides of the two species. The type-C and D gland cells exist only in Incilaria fruhstorferi, nucleoplasm was well developed heterochromatins. The type-E gland cell appears in the acinous surrounded the salivary gland of Incilaria fruhstorferi. Thdse granules appear irregular irregular shape and size and the cytoplasm is formed in alveolar. The type-F gland cells are commonly observed in the salivary glands of the two species. They are similar with the type-B gland cell, but the granular shape is comparatively small and irregular, and possess the neutral mucos granules. The type-H gland cells are mainly seen in only Achatina, and in nucleus is a well developed heterochromatin. The cytoplasm is filled with round small granules with acid mucopolysaccharide for alcianophilia observed. The type-I cell was small cell with an irregular shape and only observed in the gland cells of Achatina fulica. The heterochromatins were developed in the nucleus and the granules are not observed in cytoplasm.Secretory ducts of saliva are composed of the interlobular duct and interlobar secretory duct. In Achatina fulica the interlobular duct consists of a simple cuboidal epithelium, while the endothelium of intralobar secretory duct of Incilaria fruhstorferi consists of a simple squamous epithelium and in the cytoplasm is filled with granules(type-G secretory cell). A SDS-PAGE was carried out to confirm that the protein band pattern consist of salivary gland. In conclusions, five more bands in Achatina fulica and three bands in Incilaria fruhstorferi were confirmed in MW<29 kDa. one main band coincides comparatively with both and is between 29-45 kDa. There are four main bands in Achatina fulica and two main bands in Incilaria fruhstorferi between 45-66.5 kDa respectively. The bands in Achatina fulica seem more complex than in incilaria fruhstorferi.

The distribution of portal veins within the liver in 30 Korean native cattle were observed. Vinylite solution was injected into portal veins of eighteen specimens for cast preparation. The angiography was prepared in twelve specimens by injecting 30% barium sulfate solution into portal veins, and then radiographed on a X-ray apparatus(Shimadzu 800MA 120Kvp). The results were summarized as follow: 1. The Vena portae was divided immediately upon entering the liver into a very short Truncus dexter venae portae($14.75{\pm}4.86$ : 6.9~23.1mm) and a long Truncus sinister venae portae($94.16{\pm}9.62$ : 110~150mm). 2. The Truncus sinister venae portae runs of first in the long axis of the liver from the Porta hepatis toward the left lobe. At the boundary between the quadrate and left lobes it bends sharply 50 to 80 degrees toward the Incisura ligamentum teretis, and after a course of 36. 5 to 54.mm between the quadrate and left lobes, ends abruptly. The Truncus sinister venae portae is divided for description into the Pars transversa, from the Porta hepatis to the flexure, and the Pars umbilicalis, from the flexure to the end. 3. The branches of Venae portae were Ramus ventralis lobi sinistri, Ramus intermedius lobi sinistri, Ramus dorsalis lobi sinistri, Ramus lobi quadratii, Ramus ventralis lobi dextri, Ramus intermedius lobi dextri, Ramus dorsalis lobi dextri, Rami processus caudatorum and Rami processus papillarum. 4. The Ramus intermedius lobi sinistri was arised from the left surface of the Pars umbilicalis, and was origined on the common trunk with Ramus dorsalis lobi sinistri(3 cases, 10%) or Ramus ventralis lobi sinistri(3 cases, 10%). 5. The Rami lobi quadratii consisted of the vein(15 cases, 50%) or two veins(15 cases, 50%), and was observed on the arched-shaped at 2 cases (6.6%) of the liver. 6. The Rami processus caudatorum consisted of one vein(28 cases, 93.3%) or two veins(2 cases, 6.6%). The former were formed common trunk with R, dorsalis lobi dextri(7 cases, 23.3%) or R. ventralis lobi dextri (2 cases, 6.6%). 7. The Rami processus papillarum were arised from the dorsal border of Pars transversa, and also gave off many small branches supplied papillary process of the caudate lobe. 8. The anastomosis on the branches of Vena portae was observed in the intralobar and interlobar areas. 9. The Truncus dexter venae portae and Truncus sinister venae were ramified many secondary branches that were radiated within the liver. 10. On the diaphragmatic surface, small vessels of the portal veins were observed, while there were big ones on the visceral surface. 11. The ramified angles at Ramus dorsalis lobi dextri, Rami processus papillarum, Ramus dorsalis lobi sinistri, Ramus intermedius lobi sinistri, Ramus ventralis lobi sinistri, Rami lobi quadratii, Rami processus caudatorum, Ramus ventralis lobi dextri and Ramus intermedius were 10~50, 70~110, 100~150, 140~170, 185~220, 270~330, 240~300, 270~320 and 340~10 degrees, respectively.

Both bronchial leiomyoma and pulmonary sequestration are rare conditions, and to the best of our knowledge there are no reports of the two conditions coexisting. We report a female patient with bronchial leiomyoma with acquired pulmonary sequestration who presented with dyspnea, cough and purulent sputum. The patient had been treated for pneumonia at a local medical clinic. but was transferred to our clinic beacausr there was no clinical improvement. A 3-D computed tomography scan revealed a 1.5 cm sized mass near the distal portion of the left main bronchus and an anomalous artery arising from the aorta. The patient showed clinical improvement after a left lower lobectomy and a ligation of the anomalous artery.

Background : Pulmonary sequestration is a rare congenital malformation, which is manifested by formation of nonfunctioning lung tissue lacking normal communication with the tracheobronchial tree. The preoperative diagnostic rate has been relatively low, and without consideration of pulmonary sequestration, unexpected bleeding from aberrant vessels may be a serious problem during the operation. The purpose of our study is to describe the clinical features of pulmonary sequestration based on a review of 15 cases treated by operation. Method : Fifteen patients with pulmonary sequestration who had undergone surgical treatment from 1991 through May 1996 at Yongdong Severance Hospital and Severance Hospital were reviewed retrospectively. Results : The mean age of the patients was 22.5 years (range 5~57), and male to female ratio was 9 : 6. Clinical presentations varied from recurrent respiratory infections such as fever, cough, and sputum or chest pain to no symptom. The chest simple X-rays showed multicystic shadow(10/15) and solid mass-like shadow(5/15). The chest CT scans, done in twelve cases, showed multicystic lesion with or without lung infiltration(8/12), solid mass-like lesion(4/12), The chest MRIs, done in three cases, revealed the aberrant arteries originating from descending aorta(2/3). Aortograms, done in four cases, showed the aberrant arteries originating from descending thoracic aorta(2/4), abdominal aorta(I/4), and intercostal artery(1/4). and the venous returns were via the pulmonary veins. Pulmonary sequestration was considered preoperatively in six patients of fifteen. Other preliminary diagnosis were lung tumor(3/15), lung abscess(21/15), bronchiectasis(2/15), and mediastinal tumor(2/15). In the operative findings, twelve cases were of intralobar type and three cases of extralobar type. The left lower lobe was most often affected(9/15) and one extralobar sequestration was in the pericardium. The aberrant arteries originated from descending thoracic aorta(6/15), abdominal aorta(1/15), internal thoracic arteries (2/15), intercostal artery(1/15), pericardiophrenic artery(1/15), but in four cases, the origins could not be defined. There was no mortality or complication postoperatively. Conclusion : In our study, preoperative diagnostic rate was relatively low, and clinical features were similar to previous reports. Preoperative vigorous diagnostic approach including aortography is strongly advocated not only for its diagnostic value, but also for accurate localization of the aberrant vessels, which is major concern to surgical procedure.
