Blastogenic responses of lymphocytes from mice immunized by sublethal infection with yeast cells of Histoplasma capsulatum. 总被引:1,自引:1,他引:1 下载免费PDF全文

Blastogenic responses of spleen cells to histoplasmin and ribosomal antigens and to the mitogens concanavalin A. phytohemagglutinin, and lipopolysaccharide were studied in normal and immunized mice (10(5) live yeast cells of Histoplasma capsulatum given by the subcutaneous route). Cells (10(6) per well) were cultured with and without antigens and mitogens in microtiter plates with RPMI 1640-5% heat-inactivated normal mouse serum for 72 h at 37 degrees C. Cells were harvested after a 16- to 18-h pulse with 1 microCi of [3H]thymidine (6.7 Ci/mol), and thymidine incorporation was measured by scintillation counting. The initial blastogenic response to concanavalin A (54 X 10(3) cpm) was suppressed (P less than 0.001) from 4 to 14 days post-immunization and returned to control levels on day 21. The response to phytohemagglutinin was suppressed up to 21 days. Lipopolysaccharide responses, however, were affected to a lesser degree. Blastogenic responses to histoplasmin and H. capsulatum ribosomes were similar on day 0 in normal and immune lymphocytes, but by day 4 cells from immunized mice were more responsive (P less than 0.01). The maximum response to H. capsulatum antigens was detected on day 42 and was 9- to 16-fold higher than in controls. These results demonstrate in vitro responses of primed lymphocytes on exposure to H. capsulatum antigens and suppressed responses to mitogens during early stages of the immune response. 相似文献

In a series of 22 patients with the hyperosmolar hyperglycemic nonketotic syndrome managed during a five-year period in a community hospital setting, 21 patients were known to be diabetic and only six patients were in coma. The overall mortality was 36.3 percent, and seven of the eight deaths were explained by associated nonmetabolic causes. In this study, hyperosmolarity was not related to coma or to final outcome of treatment. Patients were managed with relatively small amounts of fluid, and the type of fluid used did not influence the final outcome. 相似文献

A patient with an unusual course of Graves' ophthalmopathy is presented; serial computed tomographic scanning of the orbits was used to follow the course of the eye disease. Right-sided unilateral ophthalmopathy first developed two years after thyroid ablation with radioactive iodine and was followed by complete resolution two years later. The remission of this patient's eye disease was short-lived; within eight months, unilateral ophthalmopathy affected the left eye, and ophthalmopathy recurred in the right eye a few months later. Current hypotheses do not readily explain the course of this patient's ophthalmopathy. 相似文献

Brainstem auditory and visual evoked potentials in Type 1 (insulin-dependent) diabetic patients 总被引:1,自引:0,他引:1
R. Khardori Dr. N. G. Soler D. C. Good A. B. DevlescHoward D. Broughton J. Walbert 《Diabetologia》1986,29(6):362-365
Summary Brainstem auditory evoked potentials and pattern shift visual evoked potentials were measured in 34 Type 1 (insulin-dependent) diabetic patients with long-standing disease and in 43 control subjects. Thirty-two percent of diabetic patients had abnormal brainstem auditory evoked potentials and 15% had abnormal visual evoked potentials. These abnormalities were not related to duration of diabetes, diabetic control or individual diabetic complications (retinopathy, nephropathy, peripheral or autonomic neuropathy). The aetiology of the abnormalities must remain a subject for speculation. The findings of this study are consistent with a central diabetic neuropathy involving the brainstem in long-standing diabetic patients. 相似文献

Treatment of metastatic liver disease is at the crossroads of an evolutionary transformation with more and more reports reiterating the benefits of resectional therapy in various cancers. A quest for application of laparoscopic approaches to the management of liver metastasis has arisen due to the projected benefits of less morbidity, early recovery, and equivalent oncological outcome in selected malignancies. However, the diverse and heterogenous data on indications, operative technique, and outcome evaluation make a comparative analysis of these studies difficult. This review is an appraisal of technique and outcome of minimally invasive liver resection as reported in the current literature with special reference to treatment of metastatic colorectal cancers. 相似文献
