[Potential use of the sauna in the long-term treatment of hypertensive cardiovascular circulation disorders--a comparison with kinesiotherapy].

The authors report about the long-term response (one and three years) of blood pressure and heart frequency under rest and load (50 W) in patients with hypertension, coronary heart disease, essential hypertension and after aortocoronary venous-bypass operation (ACVB) (n = 65) under regular visits (twice a week) to the Finnish sauna. In comparison, 68 hypertensive patients who took a regular kinesiotherapy (running and swimming) were studied. Besides the parameters of heart circulation mentioned above, peripheric microcirculation (M. tibialis anterior) by means of xenon-133 muscle clearance and central hemodynamics by means of LVEF (single probe with In 113) were studied in CHD-patients. Cardiac output at rest and under 50 W load was recorded in hypertensive patients. It was shown that regular balneotherapy had a positive effect on regulation of blood pressure and hemodynamics in patients with hypertension or CHD with hypertension, as had kinesiotherapy in hypertensive patients.

Microsurgical arteriovenous revascularization in the treatment of vasculogenic impotence.

We studied 35 patients with vasculogenic impotence who underwent an operation since 1986 and who were followed postoperatively for a minimum of 1.5 years. In all patients a microsurgical anastomosis was performed between the inferior epigastric artery and the arteriovenous shunt of the dorsal penile vessels. Potency was restored or improved in 77% of the patients during the long-term observation. Doppler or duplex sonography confirmed the same percentage of patent anastomoses. Through microsurgical modifications of the Hauri procedure and the interposition of free venous grafts, it was possible to operate further in 3 patients with short epigastric arteries and to treat intraoperative complications effectively in 1.

[The effect of health resort therapy on cardio-regulation following heart transplantation with special reference to CO2 balneotherapy].

It is being reported about the influence of a CO2-bathing series with 12 patients after heart-transplantation in connection with a light-motion therapy on blood pressure and haemodynamics. The comparative group was a group of 12 heart-transplantation patients of the same age without cure during the comparative time. It was shown that the balneotherapy after HTPL has positive effect on the development of the systolic blood pressure under rest and exercise. The peripheric microcirculation (musculus tibialis anterior) improved significantly. The left ventricular ejections fraction (LVEF) kept without change. Generally, the balneotherapy is well tolerated by heart-transplantation patients. There is no danger of a cardiac overcharge of the left ventricle.

Primary retroperitoneal tumors.

The pathological classification, diagnosis and therapy of primary retroperitoneal tumors are presented. Three typical cases from our clinical experience are described. Ultrasonography is the most important screening method for the early diagnosis of primary retroperitoneal tumors. Early diagnosis and total surgical excision offer the only hope for successful treatment.

Interferon-alpha 2b instillation prophylaxis in superficial bladder cancer--a prospective, controlled three-armed trial. Project Group Bochum--Interferon and Superficial Bladder Cancer.

Sixty-seven patients with recurrent pTa G1-G3 to pT1 G1-G3 tumors were randomized into three groups receiving either Intron A at 10 MU/instillation, Intron A at 10 MU and mitomycin C (MMC) at 20 mg/instillation or MMC at 20 mg/instillation. After a mean follow up of 6.2 months no tumor recurrence has been seen in the group receiving combined therapy, whilst four out of 22 in the interferon group and five out of 23 in the MMC group suffered a recurrence. Side effects were slight. These preliminary results suggest that a combination of the two drugs is more effective than either drug alone.

Experiments on the chemotheraphy of a transplantable glioblastoma in the rat, employing 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU).

A glioblastoma was induced in BD-II rats by weekly i.v. injections of methylnitrosourea and transplanted intracerebrally in numerous passages. The take rate was 100%. For the experiments with CCNU, solid pieces of tumour were implanted into the right parietal region. The cytostatically treated animals lived significantly longer. The untreated tumour rats had an average survival time of 18 days (counted from the time of transplantation), and the rats treated with CCNU had an average survival time of 28 days. The median values were 19 and 28 days.

[Evaluation of bone structure].

Changes in the bone structure, the periodontal space and the interdental alveolar septa are decisive criteria for evaluating the state of health of the alveolar bone. The pathological processes of alveolar bone destruction are subdivided into: reduction in height, vertical reduction and a mixed from resulting from these two.

Sperm motility under conditions of weightlessness.

The aim of this study was to determine the differences in motility of frozen and thawed bull spermatozoa under conditions of weightlessness compared with ground conditions. The tests were performed within a series of scientific and technologic experiments under microgravity using sounding rockets in the Technologische Experimente unter Schwerelosigkeit (TEXUS) program launched in Kiruna, North Sweden. Using a computerized sperm motility analyzer, significant differences were found in sperm motility under microgravity compared with sperm under gravitational conditions on earth. Computer analysis showed alterations in straight line and curvilinear velocity, as well as in linearity values. The amount of progressively motile spermatozoa, including all spermatozoa with a velocity > 20 microns/second, increased significantly from 24% +/- 9.5% in the reference test to 49% +/- 7.6% in the microgravity test. In conclusion, there is strong evidence that gravity influences sperm motility.
