Effects of methyltestosterone on immunity against Salmonella Pullorum in dwarf chicks.
This study was conducted to determine effects of methyltestosterone on innate immunity and adaptive immunity against Salmonella Pullorum in dwarf chicks. In vivo experiment, comparisons of pathological sections, viable counts of bacteria, specific antibody levels, and subsets of T lymphocytes were set forth between chicks with or without 10(-7) M methyltestosterone treatment (2 d of age through...
متن کاملAlterations in the nitrogen excretion pattern of chicks infected with Salmonella pullorum.
Investigations in our laboratory have established that infection with SalmoneUa pulorum strain CDC 3522/51 results in a decrease in arginine, methionine, glycine and tryptophan in the blood and liver of 1to 3-day old White Leghorn cockerels (Ross et al., 1955a). Subsequent experiments revealed that the administration of arginine within 24 hr following infection produced a marked increase in sur...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Effect of the administration of cortisone on the response of chicks to the endotoxin of Salmonella pullorum.
Previous investigations conducted in our laboratory have shown that the arginase system and, consequently, the Krebs ornithine cycle, is reactivated in baby chicks experimentally infected with Salmonella pullorum (Ross et al., 1956). A similar reactivation, as evidenced by an alteration in the nitrogen excretion pattern, was demonstrated in chicks treated with the endotoxin of S. pullorum (Dool...
