The presence in human serum of an inhibitory substance which is capable of neutralizing an enzyme elaborated by a strain of hemolytic streptococcus recently has been demonstrated by Friou and Wenner (1). They further showed that the amount of inhibitory substance in sera from patients with rheumatic fever was greater than in sera from patients early in the course of uncomplicated hemolytic stre...

Ecthyma contagiosum is a viral disease of sheep and goats, which is caused by Parapoxvirus. Primary cell cultures of lamb testis, lamb kidney, rabbit kidney and permanent cell lines: foetal sheep kidney (FSK), sheep foetal thymus (SFT), sheep foetal muscle (SFM), sheep plexus choroideus (SPC), bovine trachea (BTR), embryonic bovine trachea (EBTR), Madin Darby bovine kidney (MDBK) and baby hamst...

background heat is a harmful factor in workplaces that causes physiologic and cognitive changes in workers. objectives the purpose of this study was to investigate the effect of cooling vest on heat strain and reaction time while wearing chemical-biological-nuclear protective clothes. methods twelve male students with mean age of 25 ± 2 and body mass index (bmi) of 23 ± 1.5 were recruited in th...

determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. in this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. the critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. in a...
