Rat Dendritic Cells Function As Accessory Cells And Control The Production Of A Soluble Factor Required For Mitogenic Responses Of T Lymphocytes., Wolfgang E. Klinkert, Jon H. Labadie, James P. O'Brien, Carl F. Beyer, William E. Bowers
Rat Dendritic Cells Function As Accessory Cells And Control The Production Of A Soluble Factor Required For Mitogenic Responses Of T Lymphocytes., Wolfgang E. Klinkert, Jon H. Labadie, James P. O'Brien, Carl F. Beyer, William E. Bowers
Dartmouth Scholarship
Transformation of T lymphocytes, induced by treatment with periodate or with neuraminidase plus galactose oxidase, requires the participation of accessory cells. Procedures were developed for the fractionation of rat lymph node cells, by which most of the lymphocytes can be recovered as a major population of cells that do not respond to mitogenic stimulation unless accessory cells from a separated minor population are added. Further purification led to a 1000-fold overall increase in accessory activity per cell, with a 50-70% yield. The purest preparations were virtually free of macrophages and contained more than 90% typical dendritic cells. Maximum responses occurred …

A Small Area Approach To The Analysis Of Health Systems Performance, John E. Wennberg, Alan Gittelsohn
Dartmouth Scholarship
Methods and techniques for acquiring and analyzing data have been an area of primary concern for State and local health planning agencies since their initial designation. As their responsibilities have developed and the factors become more complex, the agencies have realized an even greater need for analytic processes for evaluating the performance of their health care systems and determining future directions of their programs.
Cellular Action Of Vasopressin In Medullary Tubules Of Mice With Hereditary Nephrogenic Diabetes Insipidus, Brian A. Jackson, Richard M. Edwards, Heinz Valtin, Thomas P. Dousa
Cellular Action Of Vasopressin In Medullary Tubules Of Mice With Hereditary Nephrogenic Diabetes Insipidus, Brian A. Jackson, Richard M. Edwards, Heinz Valtin, Thomas P. Dousa
Dartmouth Scholarship
Our previous studies (1974. J. Clin. Invest.54: 753-762.) suggested that impaired metabolism of cyclic AMP (cAMP) may be involved in the renal unresponsiveness to vasopressin (VP) in mice with hereditary nephrogenic diabetes insipidus (NDI). To localize such a defect to specific segments of the nephron, we studied the activities of VP-sensitive adenylate cyclase, cAMP phosphodiesterase (cAMP-PDIE), as well as accumulation of cAMP in medullary collecting tubules (MCT) and in medullary thick ascending limbs of Henle's loop (MAL) microdissected from control mice with normal concentrating ability and from mice with hereditary NDI.
Adenylate cyclase activity stimulated by VP or by …
China's Revolution In Health, Norman Miller, James C. Strickler
China's Revolution In Health, Norman Miller, James C. Strickler
Dartmouth Scholarship
China today is in the midst of a peaceful revolution that is dramatically changing the very nature of that vast country. Since the death of Chairman Mao and the political demise of the *Gang of Four," there has occurred a major re-emphasis on change and Western technology. To achieve their political goals the new regime, under Chairman Hua Kwo-Fenj, has emphasized "four modernizations": science, industry, national defense, and agriculture. Health and medicine are seen as a part of the scientific arena. The planned changes in this sector will plunge China into a Western form of technology that will certainly have …

Vermont Surgery Study, 1969-1971: On The Incidence Of Tonsillectomy And Other Common Types Of Surgery, John E. Wennberg
Vermont Surgery Study, 1969-1971: On The Incidence Of Tonsillectomy And Other Common Types Of Surgery, John E. Wennberg
Dartmouth Scholarship
The tonsils and adenoids have been subject to a widespread uncontrolled therapeutic experiment over the past half century so that at times and in certain segments of the society, less than half of the children have reached adulthood with these organs intact. While the operation has been recorded in ancient history, its popularity is associated with the advent of modern surgery and anesthesia. Tonsillectomy began to increase in frequency early in the century with a precipitous rise following World War I. Procedure rates continued at high levels since the 1930s and only in the past decade has there been evidence …
Journey In A Forgotten Land- Part 2: Food And Drought: The Broader Picture, Norman Miller
Journey In A Forgotten Land- Part 2: Food And Drought: The Broader Picture, Norman Miller
Dartmouth Scholarship
Kenya and Ethiopia handled the drought very differently, both in action and public statements. Ethiopian officials in the south spoke openly and candidly about famine and starvation and willingly gave access to mortality statistics. They also bitterly criticized the former regime for its inept attempt to deal with the famine. Kenya's administrators were cautious and guarded; they denied that any great suffering had occurred and sought to avoid publicity. Missionaries in northern Kenya were advised to give aid without fanfare, not to write home about the famine, and to keep conditions confidential.

Health information about total populations is a prerequisite for sound decision-making and planning in the health care field. Experience with a population-based health data system in Vermont reveals that there are wide variations in resource input, utilization of services, and expenditures among neighboring communities. Results show prima facie inequalities in the input of resources that are associated with income transfer from areas of lower expenditure to areas of higher expenditure. Variations in utilization indicate that there is considerable uncertainty about the effectiveness of different levels of aggregate, as well as specific kinds of, health services. Informed choices in the public …

Population Review 1970: Kenya, Norman Miller

The Republic of Kenya, located astride the equator on the Indian Ocean, enjoys the distinction of being the first tropical African nation to initiate a serious government program in population analysis and family planning. Ghana, Botswana, and the Reunion Islands off the African coast recently followed suit and have positive programs underway. By contrast, most other African states remain apathetic toward their own population problems, and a few are vigorously pronatal. Perhaps the most extreme example is Kenya's island neighbor, Zanzibar, which reportedly has introduced the death penalty for illegal abortions, and banned the sale of all contraceptives.
