Effect of hydroxyethyl starch solution in normal horses and horses with colic or acute colitis.

Hydroxyethyl starch (HES) solution is an effective colloidal infusion solution in humans for treatment of hypovolaemic shock, but it has not been compared with fluids currently available for use in horses. On the basis of plasma-expanding effect of HES in normal horses, a 10% medium-molecular 200/0.5 solution of HES was subsequently tested in hypovolaemic horses.

[Progressive paralysis caused by radiation-induced cervical malignant peripheral nerve sheath tumor].

Unlabelled: HISTORY AND DIAGNOSIS: A 59-year old engineer was admitted to the hospital because of pain in his right collar region and the onset of incomplete paresis of the right arm. Magnetic resonance tomography displayed an advanced tumour arising from the right paravertebral soft tissue. Histological examination revealed a malignant peripheral nerve sheath tumor (MPNST).

Raman resonance of electron donor/acceptor complex.

The resonance Raman excitation profiles of a number of charge transfer transitions in electron donor/acceptor complexes with tetracyanoethylene as acceptor in solution at room temperature are reported and compared with absorption and fluorescence spectra of these complexes. All complexes show distinct anomalies which cannot be accounted for by existing theories unless they are extended. In particular, the excitation profiles peak at the low energy side of the absorption profiles by amounts of the order of 1000-2000 cm-1 and also, in the cases where two charge transfer bands are present, resonance occurs independently for the two bands.
