[Significance of ofloxacin for the treatment of infection-exacerbated chronic obstructive lung disease].

The success achieved with treatment employing 2 X 200 mg oral ofloxacin administered over a period of 10 in 28 patients with COLD exacerbated by infection and requiring inpatient treatment, was comparable with that observed in 29 patients receiving treatment with established antibiotics. In elderly patients, high plasma levels of ofloxacin and frequent states of confusion were observed.

[Plasma catecholamine levels in liver disease].

To evaluate the alterations of plasma catecholamines in chronic and acute liver diseases and their complications: hepatic encephalopathy (grade 1-4), ascites, deranged metabolism, and circulatory alterations, we measured the concentrations of norepinephrine, epinephrine, and dopamine in plasma in 49 patients with cirrhosis of the liver, in 2 patients with fulminant hepatitis B, in 2 patients with acute gestational fatty liver, and in 11 patients with fatty liver. We examined 21 healthy controls. The norepinephrine concentrations in patients with cirrhosis were raised and reached the highest values in hepatic coma grade 4. As well patients with fulminant hepatitis B had excessive high norepinephrine concentrations. The epinephrine concentrations were not significantly raised in patients with toxic cirrhosis and in patients with posthepatitic cirrhosis without encephalopathy. In hepatic coma grade 4 in patients with cirrhosis and fulminant hepatitis they reached again the highest values. Patients with acute gestational fatty liver had only slightly increased, and patients with fatty liver had normal catecholamine concentrations in plasma.

Comparative quantitative aspects of putative neurotransmitters in the central nervous system of spiders (Arachnida: Araneida).

The amounts of eight putative neurotransmitters or modulators (acetylcholine, dopamine, noradrenaline, adrenaline, GABA, taurine, glutamic acid, glycine) were determined from the CNS of 12 species of five different spider families (Theraphosidae, Agelenidae, Araneidae, Lycosidae, Salticidae). Comparatively high contents of acetylcholine and noradrenaline could be found in the CNS of hunting spiders, higher contents of GABA and taurine were visible in the web-building spider families, while extraordinarily high amounts of glutamic acid were confined to the Theraphosidae. The results obtained are compared with findings from other arthropod groups and the role of putative transmitters or modulators in the spider CNS is discussed in relation to behavioural differences within the families investigated.

[Hyperoxaluria in intestinal and liver diseases].

Excretion of oxalic acid in urine was measured in 28 healthy and 97 patients with gastrointestinal diseases. We found significantly higher values in the following groups: patients after resection of parts of the small intestine, patients with sprue and other diseases with malabsorption, patients with M. Crohn of the small intestine, colitis ulcerosa and granulomatosa, patients with chronical diseases of the pancreas gland and patients with cirrhosis of the liver. In 4 patients after resection of parts of the small intestine or pancreas urolithiasis could be verified. Reduction of fat and food without ballast reduced the excretion of oxalic acid in urine. Hyperoxaluria correlied significantly with the following parameters: excretion of fat in feces, exhalation of 14CO2 in the glykocholate breath test, resorption of vit. B12 and the length of resected small intestine. This form of hyperoxaluria is caused by hyperresorption of oxalic acid from food. The mechanism of this hyperresorption is not clarified yet, an important factor seems to be ill resorption of fat.

[Hyperoxaluriaas a complication of intestinal diseases (author's transl)].

Urinary oxalate excretion was measured in healthy persons and patients with Crohn's disease, colitis ulcerosa, sprue and other diseases accompanied with malabsorption, and patients with insufficiency of the exocrine pancreas gland. Further measurements were made in patients after resection of parts of the small intestine or the colon. We found a clear increase of urinary oxalate excretion in patients with resected parts of the small intestine, sprue or other malabsorption syndromes. In 4 patients with resected parts of small intestine or pancreas we even found urolithiasis. Urinary oxalate excretion correlated significantly with steatorrhoea and increased if larger parts of small intestine were resected. Increased resorption of oxalate from food causes increased urinary excretion. Details about the patho-mechanism of this increased excretion are not known yet; an important factor seems to be the reduced absorption of fat in the small intestine.
