K. Kamino et al., FORMATION OF O-6-ETHYLGUANINE IN SPERMATOGONIAL DNA OF ADULT SYRIAN GOLDEN-HAMSTER BY INTRAPERITONEAL INJECTION OF DIETHYLNITROSAMINE, Experimental and toxicologic pathology, 47(6), 1995, pp. 443-445
17-Week-old Syrian golden hamsters received a single intraperitoneal i
njection of diethylnitrosamine (DEN) at a dose of 100 mg/kg body weigh
t. The DNA alkylation product O-6-ethylguanine was formed in the sperm
atogonia. The data demonstrate that DEN can pass the blood-testis barr
ier and be metabolized in the spermatogonia to yield an alkylating der
ivative or that externally activated metabolites themselves can pass t
he barrier.
