포항 분지 장기층군의 하부 및 상부 함탄층(마이오세)의 화석목재에 나타난 고환경 요인
박노태,김종헌 한국지구과학회 2010 한국지구과학회지 Vol.31 No.6
A paleobotanical study of the fossil woods has been carried out from the Tertiary Janggi Group, Pohang Basin. Three species belonging to three genera of Ulmus sp., Prunus sp., and Acer sp. were identified from the Lower Coalbearing Formation, and two species of two genera of Taxodioxylon sp. and Fagus hondoensis (Watari) from the Upper Coal-bearing Formation. As our specimens are mostly poorly preserved, it is difficult to give clear specific names, but mostly are all characteristic constitutional elements of the Miocene fossil woods in Korea. The values of mean sensitivity measured from the fossil woods of Lower and Upper Coal-bearing Formations are 0.367 and 0.370 respectively, but they are more than 0.30. Based on the present two data mentioned above, it stands to reason that there were many changes in the water supply to the roots of the woods or having influence to some degree each year because of the seasonal changes in rainfall. 포항 분지 제3기 장기층군에서 산출된 화석목재의 고식물학적 연구가 수행되었다. 하부 함탄층의 화석목재는Ulmus sp., Prunus sp., and Acer sp.의 3속 3종으로, 상부 함탄층의 화석목재는 Taxodioxylon sp.와 Fagus hondoensis (Watari) Watari의 2속 2종으로 각각 동정되었다. 연구에 사용한 표본은 조직의 보존성이 좋지 않아서 종의 동정까지는어렵지만, 이들은 모두 한국 마이오세 화석목재의 특징적인 구성 요소들이다. 하부 및 상부 함탄층에서 채집한 화석목재의 나이테를 분석하여 얻어진 평균민감도 값은 0.367과 0.370로 비슷하지만, 이들은 0.30보다는 약간 높다. 현재의두 그룹의 자료만으로 판단하면, 뿌리에 대한 물의 공급은 계절적인 강수량의 변화에 의해 매년 어느 정도 제한을 받았거나 물 공급에 있어 다양한 변화가 있었던 것으로 추정된다.

I have observed the changes in the anterior pituitary cells under Heidenheins Azan stain and PAS stain after removing the pituitar glands out of female matured white rats weighing 120∼150gm in body weight. Results based (based upon β-cells mainly) 1) Cyclic changes of β-cell were observed during normal estruscycle. 2) Most increase of , β-cell was observed during preestrus phase. Subsequent increases were observed in the order of estrus phase, interval phase and post-estrus phase. 3) Morphological changes of β-cell a) Multiple granules were found in the cytopiasm of the β-cells and cells were smaller in size during the interval phase. b) The amount and size of p-cell were most increased and coarse granules were appeased in the cytoplasm during the pre-estrus phase. c) The amount and size of p-cell were diminished and the granules were changed into fine nature in cytoplasm during the estrus phase along with the PAS positive material leaking from cytoplasm. d) Markedly decreaced of cell amount, cellular atrophy and remarkabl became fine granules in cytoplasm were observed during the post-estrus phase.

식욕부진(食慾不振) 및 복부팽만(腹部膨滿)을 충남대학교(忠南大學校) 농과대학부속가축병원(農科大學部屬家畜病院)에 의뢰(依賴)된 11년(年)된 암컷 잡종견(雜種犬)을 병리조직학적(病理組織學的)으로 관찰(觀察)한 바 담관세포암으로 진단(診斷)하였고 그 결과(結果)는 다음과 같다. 임상적(臨床的) 소견(所見)으로 복부팽만(腹部膨滿), 식욕부진(食慾不振), 호흡곤란(呼吸困難), 및 침울(沈鬱) 등(等)을 관찰(觀察)할 수 있었고, 혈중(血中) GOT, GPT, LDH 및 BUN등(等)은 정상치(正常値)보다 증가(增加)하였으며 총단백량 및 Albumin 은 약간 감소(減少)하였다. 육안적(肉眼的) 소견(所見)으로 간장(肝臟)은 종대, 표면(表面)에는 많은 백색(白色)의 꽃양배추양 결절(結節)이 있었으며 직경(直徑) 3~4cm의 낭형성(囊形成)이 있었다. 낭내(囊內)에는 황백색(黃白色)의 교상물질(膠狀物質)이 차 있었다. 해부학적(解剖學的)으로 본종양을 간내(肝內) 담관암으로 분류(分類)하였다. 조직학적(組織學的)으로 본종양은 관상암과 담관낭종암이 혼합(混合)되어 있었으며 관상암은 관상구조(管狀構造)가 특징(特徵)으로 내피세포(內皮細胞)는 입방형(立方形) 또는 원계형(圓桂形)이며 결합조직(結合組織)의 증식(增殖)을 볼 수 있었다. 그리고 담관낭종암은 단층(單層)및 중층입방형(中層立方形) 또는 국주형세포(國柱形細胞)로 덮혀 있었다. On 11-year-old female mixed-breed dog with chief complaints of existence of abdominal enlargement and anorexia was referred to the veterynary teaching hospital of Chungnam National University. The dog was diagnosed into cholangiocarcinoma by the result of the histopathological observation. The results observed are summarized as follows: The clinical signs were abdominal enlargement, anorexia, dyspnea and depression. There were marked increase in serum glutamic pyruvic transaminase(GPT), serum glutamic oxaloacetic transaminase(GOT), lactic dehydrogenase(LDH) and blood urea nitrogen(BUN). Serum total protein and albumin were slightly below normal. In gross finding, the liver was enlarged and friable with numerous white, cauliflower-like nodules over the surface and composed on cysts from 3 to 4 cm in diameter. The cystic lesions contained a yellow gelatinous material. Anatomically, this neoplasm was classified as intrahepatic bile duct carcinoma. Histologically, this neoplasm was combined tubular carcinoma with bile duct cystadenocarcinoma. The former were characterized by tubular structures lined by anaplastic cuboidal or columnar cells with diffuse fibrous stroma, and the latter by multiple cystic structures lined by simple and stratified cuboidal or columnar cells.
