The prognostic value of prostate-specific antigen and prostatic acid phosphatase in serum of patients with prostate cancer after orchidectomy.

Correlations between the serum levels of PAP and PSA before and 1, 3 and 6 months after orchidectomy in 27 prostatic cancer patients (advanced clinical stages C and D according to Whitemore scale) were studied. The PSA values correlated more distinctly than PAP with the general clinical condition. PSA is a reliable tumour marker when used at regular intervals, especially for monitoring therapeutic results. A high preoperative PSA level correlates with a high postoperative level and progression of the disease.

[Serum angiotensin converting enzyme (SACE) in patients with atopic bronchial asthma].

The aim of the study was to assess serum ACE (S-ACE) activity in atopic bronchial asthma. S-ACE activity values were determined in 50 subjects (11 blood donors, 39 asthmatics) using the radioenzymatic method with Ventrex Laboratories kits. The authors did not find any differences between asthmatics in clinical remission, not receiving therapy, patients receiving prednisone (mean daily dose 10.0 +/- 2.5 mg) and healthy blood donors. In subjects with exacerbations of bronchospasm (not receiving steroids) S-ACE activity was significantly higher.

Acupuncture-induced changes in human plasma insulin level.

Changes of immunoreactive insulin, glucose, and electrolytes in serum were studied in two experimental sessions, each using ten healthy volunteers, who were subjected to two different kinds of acupuncture stimulation. Immediately after acupuncture, independent of the stimulation technique used, a significant short-term decrease in insulin concentration was observed. This effect provides indirect evidence that acupuncture induces alpha-adrenergic system activity and may suggest that this system is responsible in part for acupuncture-analgesia.

Plasma immunoreactive beta-endorphin and enkephalin concentration in healthy subjects before and after electroacupuncture.

The involvement of the endogenous analgesia systems in the mechanism of analgesia produced by electrical stimulation of the brain or resulting from certain stressful manipulations seems now well-established. The purpose of the present study was to determine whether acupuncture as a method of peripheral sensory stimulation activates, like central stimulation, the endogenous opiate system. Plasma concentrations of ACTH and the best known endogenous opiates: beta-endorphin, met- and leu-enkephalin, were determined before and after standard electroacupuncture stimulation in healthy volunteers. Acupuncture stimulation resulted in a significant (p less than 0.005) decrease of plasma beta-endorphin-like immuno-reactivity (B-EPLI), but plasma ACTH assayed did not change about 5 minutes after acupuncture. The authors conclude that the reaction of the beta-endorphin system to acupuncture (sensory peripheral) stimulation in humans did not involve pituitary hypersecretion, and suggest that the increase of beta-endorphin binding to the tissue receptor sites seems to be responsible for the peripheral (plasma) B-EPLI decrease after acupuncture.
