Bactericidal Activity of Rat Leucocytic Extracts
All extract of polymorphonuclear leucocytes of the rat, prepared by means of ultrasonic vibration, was found to be bactericidal against M. aureus. The bactericidal activity was primarily confined to the mitochondrial fraction of the leucocytes. The rat leucocyte mitochondrial extract was bactericidal against both Gram-positive (M. aureus, beta-Streptococci, Diplococcus pneumoniae, Corynebacteri...
متن کاملBACTERICIDAL ACTIVITY OF RAT LEUCOCYTIC EXTRACTS II. CHARACTERIZATION" OF TttE BACTERICIDAL SUBSTANCE IN LEUCOCYTE MITOCHONDRIAL EXTRACTS
In the preceding paper (1), it was reported that rat leucocyfic extracts prepared by ultrasonic disintegration of polymorphonuclear neutrophils (leucocytes) were bactericidal against both Gram-negative and Gram-positive organisms. The bactericidal activity of these extracts was confined primarily to the mitochondria. The purpose of this report is to characterize this bactericidal substance or s...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Bactericidal Activity
as frequent in those with bactericidal activity (54%) as in those without (56%). The coexistence of bactericidal activity and bacteremia was reproduced and studied in experimentally infected weanling rats. Serum from such rats kills in vitro 95% of conventionally broth-grown bacteria within 10 min, but does not kill organisms obtained from the infected animals. Thus bactericidal activity as con...
متن کاملLeucocytic Secretions
In the present condition of the technique of cultivation of tissues, the only possible way of studying leucocytic secretions was to grow colonies of leucocytes in a medium of known properties and to examine the modifications of these properties under the influence of the living cells. The method was far from perfect, because the secretions were mixed with serum and accumulated for 48 hours in a...
