Creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) activity in serum before and after intravenous salbutamol administration of patients with bronchial asthma.

The effect of salbutamol, a selective beta 2-adrenergic agonist, on creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) activity in serum of 20 asthmatic patients was investigated. Venous blood was obtained 30 min, 2 h and 4 h after 0.5 mg salbutamol intravenous injection of 0.5 mg salbutamol. Total creatine kinase activity was assayed on a Technico RA-1000 analyzer with the IFCC recommended method. CK-MB activity was determined using a centrifugal analyzer (Cobas Fera, Roche, Switzerland). Reagent kits were provided by Boehringer Mannheim (FRG). We observed no increase of CK-activity after salbutamol, and found a statistically significant increase of CK-MB activity. Serum CK-MB activity before treatment was 13 +/- 10/IU/l after 30 minutes drug, 31.8 +/- 19 IU/l after 2 h 27.2 +/- 17.79 and after 4 h 22.6 +/- 12 IU/l. We conclude that salbutamol exerts a cardiotoxic effect.

Adenylate energy charge and the steroid 11 alfa-hydroxylase activity in Monosporium olivaceum during growth and starvation.

During growth of Monosporium olivaceum its energy charge, E.C., (i.e. the adenylates ratio ATP + 0.5 ADP/ATP + ADP + AMP) increased from an initial value of 0.59 up to 0.85 after 25 hr of growth and then decreased to 0.51. The increase of energy charge was followed by the decrease of the activity of the 11 alpha-hydroxylase of cortexolone. This occured very clearly in the starved mycelium. Highest hydroxylation activity was observed when the lowest E.C. level (0.39-0.33) was reached.

Changes in the cellular content of the pool constituents of Monosporium olivaceum -- a steroid hydroxylating mould.

Changes of the metabolic pool constitutents of Monosporium olivaceum -- a mould capable of steroid hydroxylation were examined. The experiments were carried during growth and starvation of the microorganism. The highest activity of the 11alpha-hydroxylase was observed in the mycelium which contained the lowest level of free amino acids, glucose, and mannitol. It is suggested that the inhibition of biosynthetic processes and the decrease of the respiration rate, the activity of the NAD(P)H regenerating systems maintained, provide the optimal physiological conditions for the activity of the steroid hydroxylases.
