Basic and 'special' stains for plastic sections in bone marrow histopathology, with special reference to May-Grünwald Giemsa and enzyme histochemistry.

A battery of morphological, histochemical, and enzyme histochemical stains have been experimented on semithin sections of glycol-methacrylate-embedded bone marrow biopsies. We have been able to reproduce on sections the typical 'Romanowsky effect' which characterizes May-Grünwald Giemsa-stained smears of bone marrow or peripheral blood. This appears to be of critical importance for proper routine morphological evaluation of bone marrow biopsies. Conventional histochemical stains, and the enzyme histochemistry reactions that are most useful and widely used in the study of marrow aspiration smears have been successfully applied to plastic sections: in this way the evaluation of the cytochemical profiles of marrow diseases, especially leukemias, may be included in the histopathologist's diagnostic approach, with the additional advantage of preserving the architecture of the tissue and the relationship between haemapoietic cells and stromal components.

Burns updated in China: II. Special burn injury and burns of special areas.

The pathogenesis, pathology, classification, clinical features and prognosis of pulmonary burn injury have been studied recently by Chinese surgeons. New methods to treat electrical contact burns and chemical burns are introduced in this paper. The initial attempt to use microvascular surgical technic for repairing the post-burned tissue defect has developed successfully in China.

[Developmental tendencies of gastrointestinal tumors relative to frequency and mortality with special reference to the special situation in Bavaria].

The time trends from 1952-1978 show a decreasing mortality from stomach cancer and increasing rates of cancers of the colon, rectum and pancreas in the Federal Republic of Germany. An analysis of regional trends shows that the stomach cancer rates are highest in the Federal State of Bavaria during the last 30 years. The analysis by age and birth cohorts shows a decrease of mortality rates with increasing year of birth. The effect is most pronounced in persons born after 1910 and in the age groups above 60 years. Since the regional pattern shows higher than average rates in Northeastern Bavaria and the lowest rates in the adjacent region of the Federal State of Hessen, a case control study was launched to investigate the possible reasons. This study will include hitherto considered risk factors, which are discussed, and additional information on dietary and traditional habits.
