Acute Inflammatory reaction induced by intrapleural injection of calcium pyrophosphate increases the resistance of mice to Klebsiella pneumoniae infection. Transfer to mice of protection against Klebsiella pneumoniae is effected by injection of inflammation sera. 相似文献

Summary The 30-day survival after exposure to 800 Rad60Co gamma radiation has been compared for female mice maintained on vitamin E deficient, vitamin E supplemented or regular lab rations before and/or after irradiation. Pre- or post-irradiation dietary supplementation had no effect on survival; however, injection ofa-tocopherol immediately after irradiation significantly reduced radiation lethality.Acknowledgments.

Mice peritoneal macrophages cultured in vitro release a prostaglandin-like activity as evaluated by a bio-assay using Rat stomach fundus. The prostaglandin release is greatly increased when macrophages are incubated with the supernatant of mixed lymphocyte cultures between recipient and donor of a skin allograft. This phenomenon was found in all strains of Mice tested except C3H/HeJ Mice, a strain already known for its defective responsiveness to bacterial lipopolysaccharide (LPS). 相似文献

Riassunto Sono stati studiati gli effetti del piruvato di sodio nella intossicazione acuta da cianuro nel topo. I risultati, statisticamente validi, dimostrano che il piruvato iniettato per via endovenosa riduce notevolmente l'effetto letale del cianuro di sodio somministrato per via endoperitoneale. 相似文献

Summary It was shown that, in physiological concentrations, insulin enhances, in vitro, the immunological phagocytosis of sensitized sheep erythrocytes by cultured mouse peritoneal macrophages. Insulin seems to stimulate macrophage phagocytosis as a cholinomimetic agonist by increasing the intracellular levels of cyclic GMP.Acknowledgments.

Summary Plasma erythropoietin levels during continuous exposure to hypobaric hypoxia in mice with marrow aplasia induced by whole body X-irradiation or 5-fluorouracil injection were higher than in control mice similarly exposed. These findings give support to the hypothesis that a relationship exists between erythropoietin production rate and erythroid responsiveness to the hormone.Supported by Conicet and Subcyt grants.

Glycosidase and peptidase of non-treated Mouse peritoneal macrophages were characterized. The enzymatic activities of Corynebacterium parvum stimulated Mouse macrophages were compared to those of macrophages obtained from non-treated animals. All the enzymatic activities, but beta-C-galactosidase, were higher in stimulated Mouse macrophages. 相似文献

In the Rat, after a localized freezing of the sciatic nerve inducing a complete denervation of the medial head of the gastrocnemius muscle, the reinnervation took place within 16-18 days under our experimental conditions. After only one freezing, a limited and stable "type-grouping" of muscle fibres is observed from 30 to 360 days. After 2 to 5 freezing repeated every three weeks, the muscular changes observed one month after the last freezing are much more pronounced than when only one freezing is performed. These changes consist of a progressive increase in the number of type I and type II C fibres. This transformation is not stable: 3 months after the 3rd freezing, the muscle pattern does not differ from that which is noted after a single freezing. 相似文献

It has been recently reported that the levo isomer of propranolol possesses anti-serotonin properties in animals. Since harmine-induced behavioural changes in mice are reported to be mediated through central serotonergic receptors, an attempt was made to test whether 1-propranolol would also modify harmine-induced responses by virtue of its anti-serotonergic or anti-adrenergic property. The results indicated that l- and dl-propranolol inhibited central serotonin receptor mediated responses to harmine in mice, a finding that is analogous to other recent observations. 相似文献

Resumen Se inmunizaron ratones BALB con glóbulos rojos de ratas de una línea endocriada. A estos ratones se les extrajo el ARN del bazo y se inyectó a otro grupo de animales de la misma cepa. Además, se inyectó el ARN proveniente de bazo de ratón normal a un segundo grupo de animales. Cinco días después de la inyección del ARN normal e inmune, ambos grupos, y un tercero, testigo, recibieron una inyección de glóbulos rojos de rata. 相似文献

Summary The short-time restraint of pregnant mice on day 8 of gestation led to a significant increase of the anomaly rate in fetuses. This effect may be due to stress factors of endocrine origin.The technical assistance of Mrs E. Frei is gratefully acknowledged.
