The influence of jejuno-ileal bypass surgery on mineral metabolism was studied in patients with morbid obesity before operation, and 2 and 5 years after-wards. When calcium and potassium were orally substituted post-operatively, in serum calcium fractions, parathyroid hormone, phosphate, potassium and the bone mineral content remained unchanged, while serum(More)
Damage to peripheral nerve branches triggers activation of microglia in CNS areas containing motor neuron soma and primary afferent terminals of the damaged fibers. Furthermore, microglial activation occurs in areas containing the soma and terminals of spared nerve branches of a damaged nerve. Because the abdominal viscera are innervated by spinal afferents(More)
Intraperitoneal injection of CCK reduces food intake and triggers a behavioral pattern similar to natural satiation. Reduction of food intake by CCK is mediated by vagal afferents that innervate the stomach and small intestine. These afferents synapse in the hindbrain nucleus of the solitary tract (NTS) where gastrointestinal satiation signals are(More)
Neurogenesis is important for developing certain forms of memory. Recently, hippocampal cell proliferation has been implicated in the development of drug addiction, an extreme form of emotional/motivational pathological memory. Aiming to explore the role of hippocampal neural cell proliferation in cocaine-induced conditioned place preference (CPP), we(More)
The effect on the urinary excretion of calcium of an oral cation exchange resin without phosphorus was studied in healthy control subjects and patients with recurrent calcium lithiasis under out-patient conditions. An immediate reduction of intestinal calcium absorption and urinary calcium excretion was found in five control subjects and in one patient(More)
The topographical distribution of adrenocorticotropic hormone, growth hormone and prolactin was studied in nine multihormonal pituitary adenomas and two normal adenohypophyses using quantitative immunohistochemical methods. For each pituitary hormone paraffin sections stained by antihormone antibodies were scanned with a light microscope equipped with a(More)
In 37 pituitary adenomas obtained by surgery the immunohistochemical staining for ACTH, GH and prolactin and the tumor size were related to the basal serum hormone levels. 5 adenomas were associated with Cushing syndrome, 9 with acromegaly, 17 with hyperprolactinemia and 6 were preoperatively diagnosed as inactive. A rather close correlation between(More)
