In Japan diagnostic technic of G.I. tract progressed considerably within these 15 years, particularly X ray diagnosis and endoscopic diagnosis are so advanced and generalised overall Japan that early gastric cancer is now numerously detected every year not only in university but also in smaller clinics as well. In this paper macroscopic feature of early gastric cancer is classified in accordance with the classification proposed by Japan Endoscopic Society 1962.

Experimental colonic carcinoma in a dog was induced by anal insertion of an N-ethyl-N′-nitro-N-nitrosoguanidine (ENNG) suppository (each cone containing 50 mg of ENNG) for 17 months. The dog was autopsied 20 months after the initiation insertion of the suppository. Grossly, the colonic wall from the anus to the 10-cm oral side of the colon was thickened, and there was an infiltrating tumor with shallow depressions in the rough mucosa. The lymph nodes around this portion were enlarged, and white spots were found in the liver and redness in the lungs. Histological examination of the colon revealed a variety of pathologic features, e.g., undifferentiated carcinoma, squamous cell carcinoma and malignant melanoma in the region adjacent to the anus. Well and moderately differentiated adenocarcinomas involving the proper muscle layer were found in a region oral to these tumors and were accompanied by marked invasion of the blood vessels and lymphatic permeation. There were metastases to the liver, lungs and lymph nodes which corresponded to the gross findings, and also metastases to renal glomeruli. A well differentiated adenocarcinoma and signet ring cell carcinoma were evident in the gastric mucosa. This experimental model should be useful for studies related to colonic carcinoma in humans.

SummaryThe function of residual parietal cells and G cells following selective vagotomy with pyloroplasty (SV+P) in 21 duodenal ulcer patients was assesed by light-electron microscopical studies of gastroendoscopic biopsy material and determination of gastric acid secretion and serum gastrin levels.The postoperative decrease in number of parietal cells was not so great when compared with the reduction of acid secretion. However, the ultrastructural changes of parietal cells suggested hypofunction of the cells. In addition, the response of parietal cells to histalog stimulation was also decreased according to morphological observations under electron microscope.Basal plasma gastrin was significantly increased (p< 0.01) one month after surgery. Integrated gastrin response (IGR) to meat extract and insulin hypoglycemia stimulation was also increased significantly (p< 0.01) six months postoperatively. The G cells were still increasing in number six months after SV+P, and G cell hyperplasia became more remarkable after one year. Emiocytotic figures were observed in denervated G cells which were stimulated by meat extract or insulin hypoglycemia.On the basis of the findings of this study, it is considered necessary to conduct complete vagotomy on the parietal cell region when SV+P is performed.

陥凹性早期胃癌の発育進展を検討するため, 癌巣の大きさと組織型との関係に加え占居腺領域による特性をみた. 対象は教室の単発陥凹性早期胃癌298例である. その結果, 占居腺領域を問わず分化型腺癌例は癌巣が大きくなるにつれ, sm癌の頻度が増し, 癌巣の大きさと深達度に関連性がみられたが, 未分化型腺癌例はそれらに相関関係は認められず, とくに中間帯領域に占居する未分化型腺癌例に顕著であった. 以上より, 分化型腺癌例の発育進展は同心円状進展が示唆されたが, 中間帯領域の未分化型腺癌例の進展に関しては, 多中心性発育も考慮に入れるべきものと考えられた.

本研究の目的は, われわれがこれまで出血性潰瘍に対して行ってきた保存療法と外科療法の成績を分析し, その治療方針を再検討することにある. 対象は慢性出血性潰瘍152例とストレス潰瘍を含むAGML54例である. 保存療法のうちH2受容体拮抗剤による間欠静注法の止血効果は, 軽症あるいは中等症の出血例に対しては80%以上の有効率であったが, 重症出血例に対しては30~50%と低い有効率であった. これらの無効例のうちAGMLの重症出血例に対しては, secretin 2U/kg/hの持続点滴法が有効であった. これら保存療法と内視鏡的止血法の組合わせにより, 外科療法の適応は, AGMLの重症出血の一部の例や, 穿孔あるいは狭窄をともなう慢性出血性潰瘍など限られてくる.
