متن کاملThe testicular sperm ducts and genital kidney of male Ambystoma maculatum (Amphibia, Urodela, Ambystomatidae).
The ducts associated with sperm transport from the testicular lobules to the Wolffian ducts in Ambystoma maculatum were examined with transmission electron microscopy. Based on the ultrastructure and historical precedence, new terminology for this network of ducts is proposed that better represents primary hypotheses of homology. Furthermore, the terminology proposed better characterizes the di...
متن کاملExpression of the cystic fibrosis gene in human development.
The specialised epithelia lining the respiratory tract, pancreatic ducts, male genital ducts and sweat gland ducts are defective in the severe inherited disease, cystic fibrosis (CF). We have looked at the expression of the CF gene in human fetal tissues to throw light on the development of function in specialised ductal epithelia and to determine the age of onset of the CF disease process. The...
متن کاملExperimental Study of the Effects of Scolicidal Agents on Liver Bile Ducts
SUMMARY Scolicidal agents are used by most surgeons during operations for hydatid cysts when these agents are injected into the cys t cavity, they can pass through the communicating passages between the cyst and bile ducts into the large intrahepatic and extrahepatic bile ducts and because of their caustic nature, they have the potential to damage the epithelium of ducts. This epithelial da...
