I Ni hao Nuuk møder vi den unge, rådvilde grønlænder fra Kvanefjeld, en norsk superekspert med forkærlighed for atomkraft og en nuttet kinesisk pandabjørn. Måske kan de give svar på vores spørgsmål. Kvanefjeldet er en skattekiste fyldt med råstoffer, men hvem bestemmer over skatten? Vinker grønlænderne farvel til Danmark og indgår nye alliancer? Hvor blev kineserne og deres penge af? Og hvad blev
It is not clear where analgesic measures such as morphine and acupuncture have their sites of action. Since analgesia from acupuncturelike stimulation is reversed by naloxone (Sjolund and Eriksson, Brain Res. 173:295, 1979) it is probably mediated via endorphins. The two analgesic procedures mentioned may thus use similar inhibitory mechanisms. We now present data from autoradiographic measurement
Nociceptive C fiber input to SI in the halothane-nitrous oxide anesthetized rat was assessed by recording cortical field potentials evoked by noxious thermal cutaneous stimulation with CO2-laser pulses. Morphine topically applied onto the lumbar spinal cord produced a dose-dependent inhibition of nociceptive C fiber input from the hind paw to the contralateral SI. The inhibitory effect of morphine
Aim: It has been claimed that supraspinal structures are necessary forthe depression of nocifensive behaviour elicited by acupuncture or acupuncturelike (AL) stimulation. However, nocifensive reflexes in the spinal catwere inhibited for long periods by a mechanism releasing opieids on AL conditioning stimulation of groups II-III muscle afferents (Sj~lund and Eriksson, Neurosci.Lett. S3:264:1979).
The signal level and shape of induced polarization responses are significantly affected by the current pulse duration and waveform. If not accounted for, this data dependency on the current will propagate trough the inversion to results rendering unquantifiable subsurface models. While this problem has been addressed in full-response induced polarization modelling, questions remain as to how to ac
In 50 consecutive cases of slipped capital femoral epiphysis (SCFE) from 49 families, the heredity was analyzed by radiographic examination of the first-degree relatives and by interview regarding the second-degree relatives. In four of the 49 families, SCFE was obvious in one or more first-degree relatives; and in another 13 families (14 relatives), radiographic signs of SCFE were found besides t
Lesions of the fimbria-fornix pathways are known to induce a partial cholinergic and noradrenergic denervation of the hippocampal formation, which is followed by a slow and protracted collateral sprouting by the spared afferents. Using the intracerebral microdialysis technique, compensatory changes in extracellular levels of acetylcholine (ACh) and noradrenaline (NA) have been monitored over time
Opinions differ concerning the treatment of choice for severe slipped capital femoral epiphysis, probably due to the lack of long-term follow-up evaluations on the different methods of treatment. A series of 33 patients with severe slipped capital femoral epiphysis, treated per primam with wedge osteotomy of the femoral neck, were radiographically and clinically reexamined an average of 28 years (
Levels of messenger RNA for nerve growth factor, brain-derived neurotrophic factor, neurotrophin-3, and the tyrosine kinase receptors trkA, trkB and trkC have been studied using in situ hybridization in the rat brain 2 h and four weeks after kindling-induced seizures. Epileptiform activity evoked by hippocampal stimulation and exceeding 70 s lead to a concomitant and transient increase of brain- d
Summary: The longitudinal growth rates of the distal fibula were measured, using a roentgen stereophotogrammetric method, in 32 children treated for slipped capital femoral epiphysis and compared with growth rates in a series of normal children. The growth rates in patients were similar to the growth rates in normal children, in both boys and girls. However, at the time of slippage, 13 patients ha
A male, his son, and grandson all had a slipped capital femoral epiphysis (physiolysis colli femoris - PCF). the importance of inheritance in PCF is discussed.
In 25 cases with 29 slipped capital femoral epiphyses, treated with bilateral pinning, tetracycline was administrated preoperatively. Biopsies from the femoral head and the trochanteric region were analyzed by fluorescence microscopy. All had normal tetracycline labeling except the only patient with an acute severe slip.
Five hundred thirty-two cases of slipped capital femoral epiphysis (physiolysis colli femoris - PCF) treated at three orthopedic departments in southern Sweden between 1910 and 1982 were used for epidemiologic studies. Three hundred twenty-five cases came from a well-defined area and were used for incidence analyses. During the whole period of investigation, the disease was more common in men than
Viral infections predispose to the development of childhood asthma, a disease associated with increased lung mast cells (MCs). This study investigated whether viral lower respiratory tract infections (LRTIs) can already evoke a MC response during childhood. Lung tissue from young children who died following LRTIs were processed for immunohistochemical identification of MCs. Children who died from
A monoclonal antibody to the low-affinity NGF receptor, 192 IgG, coupled to a cytotoxin, saporin, was recently introduced as an efficient selective neurotoxin for the NGFr-bearing cholinergic neurones in the rat basal forebrain. In the present study we report that an intracerebroventricular injection of this 192 IgG-saporin conjugate induces a severe, long-lasting spatial learning impairment, as a
Forty patients were treated by means of total hip arthroplasty after nailing of femoral neck fractures had failed. Their average age was 73 years. Thirty-eight patients were still alive after 2 years and were reviewed. Two hips dislocated, but there was no early mortality. The results regarding pain, walking capacity, and function were good, and total hip replacement is considered to be the salvag
