The contrecoup phenomenon. Reappraisal of a classic problem.

We describe briefly and comment upon the salient strengths and limitations of the major published theories that purport to explain the mechanism of contrecoup cerebrocortical contusions. Through the application of mechanical principles, we then present a modification, clarification, and expansion of selected aspects of several theories. Our final formulation emphasizes the injurious potential of nonuniform compressive stress and the relationship between brain lag and rotationally induced injury. The resulting theory remains faithful to the laws of physics while explaining the location and distribution of cerebrocortical contusions opposite the site of a moving head impact.

Six-year program shows benefits of shared laboratory services.

The VA Hospital in Columbia, MO, and the University of Missouri Medical Center conduct the largest shared laboratory service in the VA hospital system. Sharing has enabled these institutions to eliminate unnecessary duplication of resources, develop new laboratory capabilities in subspecialties, handle additional routine procedures, better use the expertise of senior staff pathologists, develop uniform standards, enhance quality assessment, and expand training programs.

Ultrastructure of chick tendon fibroblast with special reference to secretory mechanism.

Electron-microscope study of chick tendon fibroblast revealed a constant ultrastructural finding of a microtubular-microfibrillar system and an intimate relationship which existed between the microtubular-microfibrillar system and secretory vacuoles. Additionally, the data from this study suggest a mechanism by which newly synthesized collagen molecules are transported and secreted into the extracellular space to be organized into mature collagen.

A three-dimensional study of endometrial mitochondria during the menstrual cycle.

Three-dimensional reconstruction of endometrial mitochondria during the menstrual cycle in the woman has produced three mitochondrial populations. These populations are seen to change in size, in number, and in complexity of structure as the menstrual cycle progresses. Through reconstruction and statistical analysis, morphologic data seem to support histochemical data relating to anaerobic and aerobic metabolism in endometrial gland cells.

Inflammatory carcinoma of the breast.

Fifty-eight patients with clinical inflammatory breast carcinoma and 15 patients with "occult" inflammatory cancer (dermal lymphatic carcinomatosis without clinical inflammation) are grouped and reviewed to determine whether diagnosis is pathologic or clinical. All cases represent a retrospective study of records from the Ellis Fischel State Cancer Hospital, Columbia, Missouri. Lesions of clinically apparent and occult inflammatory carcinoma demonstrate similar gross and microscopic growth patterns, histologic types, axillary involvement and early widespread metastases. Regardless of pathologic evidence of dermal lymphatic tumor, patients with clinical inflammation had rapid deterioration. Cases with only a pathological diagnosis were slightly less fulminant in progression. Either clinical or pathologic criteria justify use of the term "inflammatory breast carcinoma" to indicate short-term prognosis despite available treatment.

Evolution of human cytogenetics: an encyclopedic essay. III. The second decade after 1956: banding techiques.

Unequivocal establishment of the correct diploid chromosome number in 1956 started the modern era of human cytogenetics. The next impetus came when the peripheral blood leukocyte culture technique for the chromosome preparation was described in 1960. Discovery of special staining procedures - banding techniques - in early seventies not only saved it from early senescence but played decisive roles in broadening the horizons of modern human cytogenetics.
