RESUMEN

Searching for a family donor other than an HLA identical sibling can be successful. The chance of finding an identical or one antigen mismatched family donor can be calculated with a computer program, so this may help in the decision making whether to perform extended family typing or not. Extended family donors are often better matched rather than unrelated donors. The reason is that they have at least one haplotype genetically identical to the patient, and that there may be some higher match grade for the minor histocompatibility antigens. Sometimes extended family donor could be the only donor for the patient. Ethical considerations have to be taken into account and extended family donors should be volunteer donors.

RESUMEN

The effects of minimal doses of insulin administered by intracerebroventricular (ICV) and intracisternal (IC) routes in mongrel dogs, on peripheral blood glucose level (BGL) have been studied. The dose of 0.1 U of insulin was found to be the minimal dose. This dose produced an immediate short lived hyperglycaemia followed by a marked and sustained hypoglycaemia. Both the effects were not observed in spinal cord transected-vagosympathectomised animals. The immediate hyperglycaemic effect was not observed in adrenalectomised animals whereas the subsequent hypoglycaemic effect did not appear only when the liver was removed. In an attempt to identify the precise site of action in the central nervous system (CNS), The cerebellomedullary angles were found to be the most sensitive sites for the action of locally applied insulin. It is suggested that insulin on central administration causes a rise in the BGL by an action on the adrenal glands and subsequently causes a marked fall in BGL by an action on the liver through some nerve fibers.
