antioxidant, antibacterial and cytotoxic effects of the phytochemicals of whole leucas aspera extract.to investigate the antioxidant, antibacterial and cytotoxic activity of whole leucas aspera (labiatae) (l. aspera) alcoholic extract.023620850
in vitro antibacterial and in vivo cytotoxic activities of grewia paniculata.grewia paniculata (family: malvaceae) has been used to treat inflammation, respiratory disorders and fever. it is additionally employed for other health conditions including colds, diarrhea and as an insecticide in bangladesh. the aim of the present study was to investigate the antibacterial and cytotoxic activities of different extracts of grewia paniculata.025949950
the etiology of acute dysentery in the united states.1. the several standard cultures used in this study are indistinguishable -a conclusion previously reached and stated by flexner. 2. the acute dysentery of the united states is due to a bacillus indistinguishable from that obtained from the epidemics of dysentery in several other parts of the world. 3. the sporadic and the institutional outbreaks of acute dysentery are caused by the same microorganism, and this organism is identical with that causing epidemic acute dysentery. 4. the cause of acu ...190219866970

the resistance of spirochetes to the action of hexamethylenetetramine derivatives and mercurial and arsenic compounds.the majority of the 76 new compounds possessed spirocheticidal powers ranging between 1: 1,000 (30) to 1:2,500 (14), while only 2 attained the power of 1:5,000, 1 of 1: 25,000, and 2 of 1: 50,000. on the other hand, 8 killed the spirochetes in a dilution of 1: 750, 10 in 1:500, 7 in 1:250. 1 in 1: 100, and 1 in 1:50. it may be mentioned that the 2 (m1, m4) of 1:50,000 and 1 (m7) of 1:25,000 belong to the mercury compounds, and that mercuric chloride kills the organisms in a dilution of 1: 100,00 ...191719868094
the survival of leptospira (spirochaeta) icterohaemorrhagiae in nature; observations concerning microchemical reactions and intermediary hosts.1. leptospira icterohaemorrhagiae is unable to grow in the urine, either with or without the addition of suitable culture ingredients, the acidity of the urine being detrimental to the growth. it survives less than 24 hours, unless the urine is neutralized or slightly alkalized, when the period of survival is somewhat longer. if suitable nutrient ingredients are added to the neutralized or slightly alkalized urine, the organism is able to grow for about 10 days, after which multiplication ceases ...191819868229
toxins and antitoxins of bacillus dysenteriae shiga.with the methods which have been described we have separated an exotoxin and an endotoxin from cultures of the shiga dysenteric bacillus. the study of the nature and effect of the poison of this microorganism is thus simplified. the two toxins are physically and biologically distinct. the exotoxin is relatively heat-labile, arises in the early period of growth, and yields an antiexotoxic immune serum. the endotoxin, on the other hand, is heat-stable, is formed in the later period of growth, and ...192019868386
divisions of the so called flexner group of dysentery bacilli.from these data it is seen that ill defined divisions of the so called flexner group exist. the divisions do not appear to be sufficiently distinct to warrant the use of separate names. to avoid confusion all mannitol-fermenting dysentery bacilli should be called bacillus dysenteriae flexner and the subdivision noted. there are two methods for this division, one by the fermentation of carbohydrates, the other by agglutination with monovalent rabbit sera. these do not coincide and one or the othe ...192019868467
studies on the phenomenon of d'herelle with bacillus dysenteriae.it has been shown that a lytic fluid for dysentery bacilli can be obtained from the peritoneum of the guinea pig by intraperitoneal inoculation of live dysentery bacilli, and that the lytic action of such a fluid is not strictly specific, but that it exerts a group action on the dysentery-colon-typhoid group of bacilli. a lytic fluid with similar effects was obtained from a child dying of flexner dysentery infection, and an anti-colon bacillus lytic fluid from a child who died of intussusception ...192119868572
ulcerative colitis due to bacillus dysenteriae, simulating pernicious anaemia. 192220314110
separation of the toxins of bacillus dysenteriae shiga.by the suppression, through anaerobiosis, of the exotoxin-producing activity of bacillus dysenteriae shiga a pure endotoxin is produced directly from the culture. the duality of the poison of shiga bacillus is further substantiated by studies on the diffusion of exotoxin, or neurotoxin, and endotoxin, or enterotoxin, by means of collodion sacs, implanted intraabdominally in rabbits or placed in vitro.192319868758

the multiplication of bacteriophage in vivo and its protective effect against an experimental infection with shigella dysenteriae.1. anti-shiga bacteriophage injected into the general circulation can multiply in the brain of mice infected intracerebrally with shigella dysenteriae. 2. under proper conditions, the injection of active bacteriophage into the general circulation can protect mice against an otherwise fatal intracerebral infection with shigella dysenteriae. 3. the protection so induced appears to depend upon the early establishment of a high bacteriophage level in the infected animal.194319871319

preparation and properties of shiga toxin and toxoid.1. shigella dysenteriae (shiga) can, under the proper cultural conditions, produce a soluble toxin which is independent of the specific somatic polysaccharide antigen. a method is described for the rapid production of this toxin by an avirulent r variant of this organism. 2. the amount of bacterial protoplasm synthesized, and the yield of toxin produced, are very much increased when the culture is grown under conditions which favor aerobic metabolism and which do not permit accumulation of organ ...194619871559

production of heteroagglutinins in haemocytes of leucophaea maderae l.it was our purpose to study the immunological activity of circulating fluid cells in the blattoid insect leucophaea maderae l. these cells are generically called haemocytes; after a preliminary morphological study under optical microscope, they were treated with anti-heteroagglutinins serum marked with fluorescein isothiocyanate. thus, it was possible to show the presence of heteroagglutinins into the cytoplasm, as regards one group of haemocytes, and on the cell membrane for the second group.19541269671
