The society of public health: 1957-1997.

History of the Period 1957-1997 The Society of Public Health: 1957-1997 is in two parts that are complementary but may be read independently of each other. Part 1: A History of the Period 1957-1997 This account details the progress and activity of the last forty years of the Society of Public Health (previously The Society of Community Medicine: Originally The Society of Medical Officers of Health) before its ammalgamation with the Royal Institute of Public Health and Hygiene to form The Royal Institute of Public Health and Hygiene and Society of Public Health. The appendices to this account cover the Presidents of The Society and Its Branches (Home And Overseas) and Special Interest Groups, Editors, its Faculty, Awards and Conferences since the Society's establishment in 1856 or their own beginning, as appropriate. Published in Public Health (2000) 114, 73-107 Part 2: Profiles of Some Fellows of the Society of Public Health To be published in Public Health (2000) 114, (3) This consists of profiles of eminent people active within the Society and the wider discipline of public health during the period 1957-1997. As it is based on availability of information the series cannot be all inclusive and readers are invited to consult the history in Part 1 and the listings in its appendices for additional information regarding members of the Society of Public Health.

Knife blade as a facial foreign body.

This case demonstrates the unpredictability of foreign bodies in the face. The retained knife blade eluded detection on two separate examinations. The essential components to making a correct diagnosis of a foreign body following a stabbing to the face include a thorough review of the mechanism of injury, a complete head and neck examination, a high index of suspicion, and plain radiographs of the face.

Sensitivity of mouse Skh:HR-2 to ultraviolet radiation: melanocyte inactivation.

The hairless mouse, Skh:HR-2, was exposed to doses of ultraviolet (UV) radiation known to induce skin pigmentation. Three parameters associated with perturbations in skin pigmentation were monitored following UV exposure. These include spectroscopy (skin darkness), histology (melanocyte density), and biochemistry (melanin). Within 90 min of UV exposure, the skin became lighter. This was associated with a reduction of quantifiable melanin and the inactivation of epidermal melanocytes.

Comparative toxicity of 226Ra, 239Pu, 241Am, 249Cf, and 252Cf in C57BL/Do black and albino mice.

Groups of C57BL/Do (black and albino) mice were injected with graded activities of 226Ra, 239Pu, 241Am, 249Cf, or 252Cf and were followed throughout life. Bone sarcoma was the principal radiation-induced end point, and the risks associated with average skeletal doses of the four transuranium radionuclides, relative to radium, were determined. The relative biological effectiveness (RBE) was calculated for each emitter by dividing its risk coefficient (bone sarcomas per 10(6) mouse-rad) by the risk coefficient for 226Ra. Combined data for males and females in both black and albino mice gave the following values +/- SD for the RBE relative to 226Ra = 1.0: 239Pu = 15.3 +/- 3.9, 241Am = 4.9 +/- 1.4, 249Cf = 5.0 +/- 1.4, and 252Cf = 2.6 +/- 0.8. About 70% of the tumors occurred in the axial skeleton, and the risk coefficient for females averaged about four times higher than for males when all five nuclides were included. The RBE of fission fragment irradiation from 252Cf for cancer induction, relative to alpha irradiation, for the combined data in all of the animals given 252Cf and 249Cf, was 0.02 +/- 0.28, in agreement with the calculated theoretical value of 0.03, based on the ratio of summed track lengths in tissue.
