Mucosal damage induced by various gastric carcinogens in the glandular stomach of the rat.

The process of erosion formation in the glandular stomach of the rat given single and multiple intragastric doses of 100 mg N-methyl-N'-nitro-N-nitrosoguanidine (MNNG)/kg body weight, was studied histologically, histochemically, and ultramicroscopically and compared with erosion induced by other gastric carcinogens and erosion-forming chemicals. The acute effect of several nongastric carcinogens on the glandular mucosa was also studied. The earliest degenerative transformation, fatty change, was found in the surface mucous cells within 1 hour a one-pulse intragastric dose of 100 mg MNNG/kg body weight; the change gradually progressed into deeper glandular cells and after three successive doses, erosion was complete in every rat. Ultrastructurally, four main glandular cells showed essentially similar degenerative alterations. Fatty change was also induced by other gastric caricnogens such as 4-nitroquinoline-1-oxide, methylnitrosocyanamide, methylnitrosourea, N-2-fluorenylacetamide, and iodacetamide, a noncarcinogenic alkylating agent. Mucosal damage induced by acetylsalicylic acid and thermal burn did not show fatty change. Nongastric carcinogens failed to induce mucosal damage. The relationship of the carcinogen-induced fatty change and mucosal damage to carcinogenesis was discussed.

The surgical management of massive gastro-intestinal hemorrhage due to stress ulcer following surgery.

In this paper, thirty-six cases complicated by gastrointestinal bleeding after various operations were reviewed. The mortality rate was 47.2%. In 20 surgical cases, the mortality rate was 35.0%. Especially in the cases of post-intracranial surgery, a remarkably better result was obtained by surgical than by conservative treatment. With reference to the better results of surgical treatment, we suggested that the surgical indication depended on a stressor due to the original postoperative phase, which induced a stress ulcer. In post-CNS surgery, operative treatment should not be performed in a comatose patients. As regards jaundiced patients, those with low improved bilirubin levels should be preferred to those with infected bile ducts. In cases of abdominal surgery, sepsis and functional failure of the liver and kidney must be taken into consideration. From our clinical experience, subtotal gastrectomy combined with truncal vagotomy appears to be a more satisfactory treatment for stress ulcers than gastrectomy or vagotomy alone.

Success in the radical resection of esophageal cancer with artificial blood infusion: case report.

Using the oxygen-carrying, so-called "artificial blood", Fluosol-DA, developed by us, we successfully performed a radical resection for esophageal cancer and a one-stage reconstruction, without any blood transfusion. The operation was performed quite safely despite a large blood loss, a stable condition was performed quite safely despite a large blood loss, a stable condition being maintained during and after the operation. Fluosol-DA has no relation to blood type and is stable in a frozen state for one year or more and can, therefore, be used conveniently and safely for treating severe and intraoperative hemorrhages. Furthermore, this preparation may well have at wide application because it greatly reduces the risk of postoperative hepatitis.
