Apoptosis in murine lymphoid organs following intraperitoneal administration of dimethyl sulfoxide (DMSO).

A significant increase in lymphocyte apoptosis was detected by the TUNEL method in the thymus, spleen, and Peyer's patches (PP) following intraperitoneal (i.p.) administration of dimethyl sulfoxide (DMSO) (treatment, n = 47; control, n = 8).

[A study of the relationship between community networking and confidentiality].

Legal and ethical conflicts arise in building a community network for mental health workers with confidentiality. Another ethical problem is encountered by involving mental health volunteers who are not obliged to be confidential. The authors made a questionnaire from the following six points of view: 1) the current attitudes of mental health professionals and workers toward confidentiality, 2) the degree of disclosure of individual information, 3) the relation between collaboration with family and confidentiality, 4) the range of extended confidence, 5) the extent of sharing individual information with volunteers, 6) the guidelines of confidentiality.

Acinar cell carcinoma of the pancreas showing finger-print-like zymogen granules by electron microscopy: immunohistochemical study.

A rare case of finger-print-like zymogen granules shown by electron microscopy is reported. The patient was a 75-year-old man who was histologically and ultrastructurally confirmed to have acinar cell carcinoma of the pancreas. Frozen section and postmortem examination revealed that the tumor was made up of solid nests of cells resembling the appearance of normal pancreatic acini, showing polygonal cells which had round or oval nuclei, and rare mitotic figures.
