    Notes: Summary In this study the immunoperoxidase technique was used to demonstrate the blood group antigens A, B and H in normal gastric mucosa and primary and metastatic gastric carcinomas. No clear relationship between tumour differentiation and preservation of blood group antigens was found. In some well differentiated tumours there was a marked loss of blood group substance, whereas in other poorly differentiated tumours, both primary and metastatic, it was easily detectable. In some tumours an inverse relationship between A or B and H activity was noted. This observation is consistent with the theory that in some malignant cells there is a blocking of the normal step-by-step elongation of the carbohydrate portion of blood group substances.

    Notes: Abstract Primary carcinoma of the bronchus is a major cause of death in males and females. Several studies report an increase in the incidence of adenocarcinoma and have suggested that this reflects changes in smoking habits or, alternatively, that it is a spurious rise due to changes in diagnostic criteria. To examine the latter suggestion we reviewed three cohorts of bronchial carcinoma from 1970, 1980 and 1990, using immunocytochemical techniques to refine diagnosis. We found that squamous cell carcinoma had been consistently overdiagnosed and adenocarcinoma and adenosquamous carcinoma consistently underdiagnosed in all groups. Also, many tumours showed evidence of divergent differentiation with both squamous and glandular components present. There was a small, but real temporal increase in the proportion of adenocarcinoma over the 10 years between 1970 and 1980, but this was not sustained between 1980 and 1990.

    Notes: Summary 1. It is thought that the extensive system of nerves passing into the wall of the anterior vena cava in Eledone cirrosa has a neurosecretory function. Examination of the fine structure of the nerve terminations demonstrated the presence of large numbers of electron-dense granules similar to those described in known neurosecretory tissue. 2. Extracts of the anterior vena cava have a persistent excitatory effect on the isolated Eledone heart. The activity is not attributable to 5-hydroxytryptamine, noradrenaline or adrenaline. The active factor is heat stable. The greatest level of activity was found in the inner layers of the vessel in the region where the nerves pass into the wall of the vessel, i.e. the distribution of the active principle parallels that of the nerve terminations in the vein. 3. The physiological role of the system is discussed.
