ANTIPNEMOCOCCUS PROTECTIVE SUBSTANCES IN NORMAL CHICKEN SERUM*

The Presence of Protective Substances in Human Serum during Lobar Pneumonia

These experiments demonstrate that protective substances are usually present in the blood of patients recovering from lobar pneumonia. As a rule, the appearance of protective bodies in the blood, when demonstrable, coincides rather sharply with the period of critical fall in temperature and the disappearance of symptoms. These substances are not present in the blood in any measurable degree bef...

Increasing of serum nitric oxide metabolites in chicken Eimeria infection

In order to determine the involvement of nitric oxide in the pathogenesis of coccidiosis induced by Eimeria, 30 chickens were challenged with mixed sporulated oocysts of four species of Eimeria (E. acervulina, E. maxima, E. necatrix, and E. tenella) at 26 days of age. There was an increasing of oocyst shedding in the infected birds at 6, 10 and 14 days post-infection. Histopathological examinat...

Naturally occurring substances and their role in chemo-protective effects.

Cancer chemoprevention is defined as the use of natural, synthetic or biological chemical agents to reverse, suppress or prevent carcinogenic progression of invasive cancer. Carcinogenesis is a complex multi-step process; therefore, it is necessary to attack cell proliferation, stimulate apoptosis and inhibit angiogenesis. There have been more than 60 randomised trials using chemopreventive pot...
