Dietary polyunsaturated fats and malignant melanoma.
The consumption of polyunsaturated fat of a group of patients with malignant melanoma was compared to that of various groups of control subjects to determine whether such dietary fats predispose to the development of malignant melanoma. The results are tabulated with reference to various associated factors, and a statistical assessment of their significance is presented. The writers were unable to agree on the interpretation of the results, and present two opposing views on whether the ingestion of polyunsaturated fat is associated with the incidence of malignant melanoma.

Response of leukocytes in chickens infected with the avian schistosome Austrobilharzia variglandis (Trematoda).
Leukocyte levels were monitored weekly in chickens infected with the avian schistosome Austrobilharzia variglandis. Changes in relative and absolute numbers of leukocytes were recorded over a 7-week period beginning 1 week before exposure. There was a significant increase (P less than 0.001) in total leukocytes, peaking at 5.8 X 10(4) cells/mm3 on day 21 postexposure; controls had 2.4 X 10(4) cells/mm3 on that day. The leukocyte count declined over the next 3 weeks, returning to nearly normal levels by day 42 postexposure. With the exception of eosinophils, which peaked 35 days postexposure, all leukocyte subpopulations peaked in number on day 21. Increases in heterophils and monocytes were related to the schistosome egg burden.
A new method for the identification and enumeration of chicken heterophils and eosinophils.
A method for the direct counting of chicken heterophils and eosinophils using Phloxine B stain and a hemacytometer is described. A solution of 0.1% Phloxine B in 50% propylene glycol stained heterophils and eosinophils obtained from peripheral blood. The cytoplasm of heterophils became completely stained, whereas that of the eosinophils stained incompletely, thereby enabling these cells to be distinguished easily from each other. Identification of cell type was confirmed by comparing cell counts prepared from blood smears stained with Wright's stain with wet mounts (hemacytometer preparations) stained with Phloxine B.
