Treatments with copper sulphate (CuSO4), paraquat (PQ) and methidathion (MD) caused tissue damage and stress effects in carp, indicated by the increased lactate dehydrogenase (LDH), glutamic oxaloacetic transaminase (GOT), and glutamate dehydrogenase (GIDH) enzyme activities and elevated blood-sugar levels. Copper sulphate, administered together with PQ and MD, were synergistic in terms of tissue damage and stress effects. The isoenzyme patterns showed organ-specific tissue damage. The administered chemical and isoenzymes indicating liver damage were detectable in the blood. The combination of CuSO4 and MD caused focal cell necrosis, which was observable in the liver tissue by light microscopy. Electron microscopic studies revealed the presence of damaged parenchymal cells with electron transparent cytoplasms, myelin figures, and altered mitochondria ER and Golgi.

Control of hypertension with single daily doses of sotalol hydrochloride.

A study was carried out in 12 previously untreated hypertensive patients to assess the efficacy of sotalol given in a once-daily dosage regimen. After an initial dosage titration period (mean 3 weeks) during which diastolic pressure was stabilized at less than 100 mmHg, all patients were satisfactorily maintained on a constant once-daily dose of sotalol for 3 months. Eight of the 12 patients required 320 mg or less daily (mean dose 190 mg). Whilst blood pressure remained controlled for at least 26 hours after daily doses the pulse rate, counted at the same time, showed escape from beta-blockade. Side-effects (vivid dreams) were reported in only 1 patient.

[Profilographic studies with 99mTc-pertechnetate in joint diseases in children].

The inflammatory activity of joints can be stated after intravenous administration of 99mTc-pertechnetate by demonstration of an enrichment of isotope. In 85 out of 111 patients (77%) a good accordance between profilogram and clinical finding could be seen. "False positive" results could be found in juvenile rheumatoid arthritis, ulcerative colitis, reactive arthritis and juvenile gout. In some cases of juvenile rheumatoid arthritis the clinical finding is later obvious than the demonstration by nuclear medicine. "False negative" results mainly can be seen at the wrists of patients with juvenile rheumatoid arthritis and tendosynovitis as well as in already existing radiological changes of the bones. Differential diagnostical evidences of profilography cannot be expected with the investigation technique used here. It, however, may contribute to assure the diagnosis in non-inflammatory joint diseases ("psychogenic rheumatism", lymphatic oedema).
