Effects of administration of cannabis resin during pregnancy on emotionality and learning in rats' offspring. 1980

G F Kawash, and D L Yeung, and S D Berg

Injection of cannabis resin as a saline-Tween 80 solution to pregnant rats resulted in pups having lower body weight, higher emotionality, poorer learning capacity, and paradoxically higher brain weight and DNA content. The cannabis appeared directly to have caused the inferior growth rate of the pups which in turn affected emotionality and learning.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
