Notes: Summary The three-dimensional structure of the bile ducts and their relationship to the blood vessels were studied in the larval lamprey by scanning electron microscopy of the intact tissue and of biliary and vascular casts. The intrahepatic gall bladder is situated in the cephalic portion of the liver and a cystic duct is connected to a straight intrahepatic common bile duct, which extends to the extrahepatic bile duct at the caudal end of the liver. Several smaller intrahepatic common bile ducts are connected directly to the intrahepatic common bile duct, are convoluted or serpiginous and are surrounded intimately by sinusoids. This arrangement enables the bile ducts to have increased surface area exposed to blood vessels. The functional significance of this arrangement is discussed with respect to the modification of bile through the transport of solutes and the similarity of this bilio-vascular relationship to the peribiliary vascular plexus of the mammalian liver.

Notes: Measurements of plating efficiency, accumulation of metaphases and generation times have shown that fibroblast from patients with Fanconi anemia (FA) have decreased probability of completing a further division after successful mitosis. Thus FA cells show decreased growth rates and increased generation times. We have also measured the survival of FA fibroblasts and lymphoblasts after treatment with a variety of mutagens. All FA cells show an increased sensitivity to drugs such as MMC and psoralen plus long wave length UV which cause DNA interstrand crosslinks. FA strains show varying degrees of sensitivity to these drugs and the extent of this sensitivity seems to be characteristic of each patient. FA cells are equal to controls in their sensitivity to other alkylating agents such as ethyl methane sulfonate, N-methyl-N1-nitro-N-nitrosoguanidine and actinomycin D. Both the decreased growth and increased drug sensitivity may result from defect in DNA replication or repair.
