Does treatment with tetrahydrocannabinol ( THC ) prevent infertility in male cystic fibrosis mice?
The present study shows that (i) endocannabinoid function is impaired in CF mice, as evidenced by the regenerating effect of its stimulation on the fertility of otherwise infertile males, (ii) endocannabinoid system dysfunction is apparently the determining factor causing infertility in CF, and (iii) mild stimulation of the endocannabinoid system in infancy and adolescence appears to normalize many reproductive processes and thereby prevent infertility in CF males.
Unstable cervical spine injuries secondary to explosion are extremely rare. The majority of unstable cervical spine fractures were secondary to penetrating injuries, with irreversible neurologic deficits on admission. The application of SRCC did not seem to be of any benefit in these patients and might pose a risk of obscuring other neck injuries. We recommend that SRCC will not be used in the prehospital management of victims of explosions.
