Abstract
The functional spectrum of the teleostean head kidney covers haematopoietic, immune and endocrine signalling pathways with physiological effects that are likely to conflict if activated at the same time. An in vivo experiment on the salmonid fish maraena whitefish (Coregonus maraena) revealed that the head kidney shows a remarkably strong response after injection of Aeromonas salmonicida within 48 h. In order to investigate the potential influence of endocrine signalling on the initiation of immune responses, we established a primary culture of head-kidney cells of maraena whitefish. For the characterisation of this model system, we used flow cytometry complemented with an extensive panel of immunological/haematological and stress-physiological/neuroendocrinological qPCR assays. More than one third of the cells expressed the characteristic signature of myeloid cells, while more than half of the cells expressed those genes typical for lymphocytes and monocytes. In parallel, we quantified the expression of genes encoding endocrine receptors and identified ADRA2D as by far the most highly expressed adrenergic-receptor gene in head-kidney cells. The stimulation of the head-kidney cells with toll-like receptor ligands induced the expression of typical immune genes (IL1B, CXCL8, TNF, SAA) after only 1 h. The incubation with the stress hormones cortisol, adrenaline and noradrenaline also had an immune-activating effect, though less pronounced. However, cortisol had the strongest suppressive effect on the stimulation-induced immune response, while adrenaline exerted a comparably weaker effect and noradrenaline was almost ineffective. Moreover, we found that cortisol reduced the expression of genes coding for adrenergic and some glucocorticoid receptors, while noradrenaline increased it. In conclusion, the primary head-kidney cells of maraena whitefish reflect the immunological and neuroendocrinological diversity of the entire organ. This in vitro system allowed thus identifying the correlative changes between the activities of hormones and immune factors in salmonid fish in order to contribute to a better understanding of the regulation circuit between stress and immune defence.

Abstract
In stock enhancement and sea-ranching procedures, the adipose fin of hundreds of millions of salmonids is removed for marking purposes annually. However, recent studies proved the significance of the adipose fin as a flow sensor and attraction feature. In the present study, we profiled the specific expression of 20 neuron- and glial cell-marker genes in the adipose fin and seven other tissues (including dorsal and pectoral fin, brain, skin, muscle, head kidney, and liver) of the salmonid species rainbow trout Oncorhynchus mykiss and maraena whitefish Coregonus maraena. Moreover, we measured the transcript abundance of genes coding for 15 mechanoreceptive channel proteins from a variety of mechanoreceptors known in vertebrates. The overall expression patterns indicate the presence of the entire repertoire of neurons, glial cells and receptor proteins on the RNA level. This quantification suggests that the adipose fin contains considerable amounts of small nerve fibers with unmyelinated or slightly myelinated axons and most likely mechanoreceptive potential. The findings are consistent for both rainbow trout and maraena whitefish and support a previous hypothesis about the innervation and potential flow sensory function of the adipose fin. Moreover, our data suggest that the resection of the adipose fin has a stronger impact on the welfare of salmonid fish than previously assumed.

Abstract
This report deals with 26 cases of uterine rupture seen in Hamburg-Eppendorf in the gynaecological hospital of the University during the years 1968 to 1982. The frequency of such rupture was 0.1% in relation to the total number of deliveries. Approximately 92% of the cases were due to a previous Caesarean section. There was no maternal death, although the maternal complication rate was high. The corrected perinatal mortality rate in relation to a rupture of the uterus was 3.8% during the period under review.

Abstract
In the treatment of minor blunt injuries several topical drugs are known to have anti-inflammatory and analgesic properties. They represent, however, two fundamentally different major pharmacological therapy approaches: the "chemical-synthetical" and the "phytotherapeutical" approach. The main objective of this trial (CODEC_2004) was to compare the efficacy and tolerability of an ointment of Comfrey extract (Extr. Rad. Symphyti) with that of a Diclofenac gel in the treatment of acute unilateral ankle sprain (distortion). In a single-blind, controlled, randomized, parallel-group, multicenter and confirmatory clinical trial outpatients with acute unilateral ankle sprains (n=164, mean age 29.0 years, 47.6% female) received either a 6 cm long ointment layer of Kytta-Salbe f (Comfrey extract) (n=82) or of Diclofenac gel containing 1.16 g of diclofenac diethylamine salt (n=82) for 7 +/- 1 days, four times a day. Primary variable was the area-under-the-curve (AUC) of the pain reaction to pressure on the injured area measured by a calibrated caliper (tonometer). Secondary variables were the circumference of the joint (swelling; figure-of-eight method), the individual spontaneous pain sensation at rest and at movement according to a Visual Analogue Scale (VAS), the judgment of impaired movements of the injured joint by the method of "neutral-zero", consumption of rescue medication (paracetamol), as well as the global efficacy evaluation and the global assessment of tolerability (both by physician and patient, 4 ranks). In this study the primary variable was also to be validated prospectively. It was confirmatorily shown that Comfrey extract is non-inferior to diclofenac. The 95% confidence interval for the AUC (Comfrey extract minus Diclofenac gel) was 19.01-103.09h*N/cm2 and was completely above the margin of non-inferiority. Moreover, the results of the primary and secondary variables indicate that Comfrey extract may be superior to Diclofenac gel.

Abstract
OBJECTIVES To investigate the clinical efficacy and safety of a newly developed diclofenac patch in the topical treatment of blunt impact injuries. METHODS This was a randomised, placebo controlled, double blind, multicentre study in 120 patients with traumatic blunt soft tissue injury. Within 3 h of the injury participants of sport competitions and training camps were enrolled and treated twice daily with the diclofenac or a placebo patch over a period of 7 days. Patients were randomised (1:1) to two parallel groups. Tenderness produced by pressure was measured twice daily during the first 3 days after enrollment as well as at day 7. Tenderness was defined as the amount of pressure (measured by a calibrated caliper at the centre of the injury) that first produced a pain reaction as reported by the patient. RESULTS The primary efficacy variable was the area under the curve for tenderness over the first 3 days. The diclofenac patch was significantly more effective than placebo (p<0.0001). The treatment effect was 64.7 kp h/cm2 (95% confidence interval 48.7 to 80.9) between diclofenac and placebo patches. These results were supported by all secondary efficacy variables. The diclofenac patch produced rapid pain relief as reflected by the time to reach resolution of pain at the injured site which was significantly shorter compared to placebo (p<0.0001). The diclofenac patch was well tolerated. The most frequently observed adverse events were local cutaneous adverse reactions (pruritus, rash) of minor severity occurring with the same frequency as in the placebo group. CONCLUSIONS A newly developed diclofenac patch is effective and safe for the treatment of blunt impact injuries.

Abstract
Comfrey (Symphytum officinale L.) is a medicinal plant with anti-inflammatory, analgesic and tissue regenerating properties. In a double-blind, multicenter, randomized, placebo-controlled, group comparison study on patients suffering from unilateral acute ankle sprains (n = 142, mean age 31.8 years, 78.9% male), the percutaneous efficacy of an ointment of comfrey extract (Kytta-Salbe f, four treatments per day for 8 days) was confirmed decisively. Compared to placebo, the active treatment was clearly superior regarding the reduction of pain (tonometric measurement, p<0.0001, as the primary efficacy variable) and ankle edema (figure-of-eight method, p = 0.0001). Statistically significant differences between active treatment and placebo could also be shown for ankle mobility (neutral zero method), and global efficacy. Under active treatment, no adverse drug reactions were reported. The good local and global tolerance of the trial medication could also be confirmed. The study results are consistent with the known pre-clinical and clinical data concerning comfrey.

Abstract
Ozonation of industrial and sewage sludge is a suitable process for minimizing the sludge production of activated sludge processes. The ozonation has the advantage for complete oxidation of volatile suspended solids (VSS) of combining partial sludge oxidation with subsequent biological oxidation. This paper describes the evaluation of two full-scale sewage sludge ozonation investigations for subsequent aerobic stabilisation as well as for subsequent anaerobic stabilisation compared to different sludge treatment processes. For both the anaerobic and aerobic application, sludge liquefying by release of 110 and 160 mg COD per g total suspended solids (TSS) has been reached at specific ozone consumption of 0.03 and 0.06 kg O3 per kg TSS, respectively. The subsequent biological treatment has reached a mass reduction of 20-35% for the aerobic and 19% for the anaerobic stabilisation. For both applications the specific ozone consumption was about 0.05 kgO3 per kg TSS to be treated. A comparison with mechanical and thermo-chemical sludge mass reduction methods shows that the mass reduction potential of ozonation is presently higher. Even though costs for sludge ozonation are higher compared to other methods, the optimisation potential for cost reduction of sludge ozonation is obvious from the results presented in this paper.

Abstract
AIM To analyze the anti-inflammatory and analgetic properties of the topical comfrey, preparations Kytta-Salbe f, Kytta-Plasma f and Kytta-Balsam f applied to bruises, sprains and distortions and painful conditions of the muscles and joints. METHOD A prospective open multicentric observational study complying with paragraph 67(6) of the AMG and involving 162 general practitioners. During the two-week period of observation, the patients received an average of one to three applications of the comfrey preparation per day. All 492 questionnaires were evaluated. Efficacy and tolerability were assessed by both physician and patient. RESULTS Pain at rest and on movement, as also tenderness, improved in the overall observation group by an average of 45-47%. The duration of morning joint stiffness decreased from 20 minutes initially to 3 minutes. During the course of treatment with comfrey, more than two-thirds of the patients were able to reduce or even discontinue their intake of non-steroidal anti-inflammatory drugs and other specific concomitant medication. In most of the cases, both effectiveness and tolerability were assessed to be excellent or good. CONCLUSION The results of the study confirm the effectiveness and tolerability of the topical comfrey preparation investigated in the treatment of bruises, sprains and distortions as well as painful conditions affecting muscles and joints.

Abstract
Approximately 20 to 30% of patients with idiopathic nephrotic syndrome and focal glomerulosclerosis experience a relapse of their nephrotic syndrome after transplantation. Previously, it has been shown that ex vivo immunoadsorption on protein A strongly (although transiently) reduces proteinuria in relapsing patients. To investigate whether the factor(s) that give rise to albuminuria are bound directly to protein A in the immunoadsorption procedure or are part of a complex with Ig, four patients with relapse of focal glomerulosclerosis presenting as nephrotic syndrome after transplantation were treated, sequentially, using a (non-protein A) anti-Ig affinity column and a protein A column. This study reports that the effect on proteinuria of immunoadsorption using an anti-Ig immunoaffinity column is comparable in its magnitude and kinetics to that of immunoadsorption on protein A. The two procedures were also equally effective in depleting the relapsing patients' plasma of a factor capable of altering the albumin permselectivity of isolated glomeruli in vitro. This study demonstrates for the first time that immunoglobulins have a role in the nephrotic syndrome. In addition, the fact that the two different immunoadsorption procedures both resulted in the removal of the same putative albuminuric factor in these patients and that no autoreactivity of eluted immunoglobulins was observed on human tissues strongly suggests that the factor or factors that may be responsible for immediate nephrotic syndrome after transplantation are bound to an immunoglobulin. However, no firm evidence can be yet provided against a direct role of immunoglobulins.

Abstract
The effect of insulin-like growth factor-I (IGF-I), epidermal growth factor (EGF), fibroblast growth factor (FGF) and nerve growth factor (NGF) on production of oxytocin and progesterone by cultured bovine granulosa and luteal cells was studied. Secretion of oxytocin was stimulated, in a dose-dependent manner, by IGF-I at 48 and 120 h of culture to levels much higher than those after stimulation with LH, FSH, EGF, FGF or NGF. A similar effect of IGF-I was observed for progesterone but, in contrast to oxytocin, secretion of progesterone was not increased by EGF, NGF or FGF. During primary culture, for 4 h, of dispersed bovine luteal cells obtained from corpora lutea between days 4 and 10 of the oestrous cycle, all the growth factors tested failed to stimulate secretion of oxytocin or progesterone. The data suggest the relevance of growth factors (especially IGF-I) for ovarian physiology and their possible importance for differentiation of follicles and luteinization.

Abstract
In the bovine ovary there is a delay of 4-6 days between the observed maximum of oxytocin mRNA and the peak in the luteal levels of oxytocin nonapeptide. This implies a maturation process involving components of the post-translational processing pathway. In situ hybridization shows the oxytocin gene to be transcribed exclusively in the large cells of the corpus luteum at the beginning of the estrous cycle.

Abstract
Immunoreactive oxytocin was measured in ovaries (corpus luteum and follicular fluid) and adrenals of cows, and in testes, seminal vesicles, prostate gland and adrenals of bulls. Secretion of oxytocin was further measured after culture of whole follicles, granulosa cells and theca tissue. Concentrations of oxytocin increased in corpora lutea of cycling cattle until mid-luteal phase (447 +/- 93 ng/g wet weight) and decreased afterwards. Low concentrations were found in corpora lutea of pregnant animals (6 +/- 3 ng/g wet weight). Follicular fluid contains some oxytocin (on average 42-108 pg/ml) but concentrations were significantly higher in the fluid of ovarian cysts (190 pg/ml). After culture of follicles the amount of oxytocin released into the medium increased indicating de novo synthesis. The granulosa cells were the main source of follicular oxytocin. Production increased during luteinization indicating that luteinization is an important step for the production of oxytocin in ovaries. Tissues of testes (65 +/- 10 pg/g wet weight) and adrenals from cows (122 +/- 39 pg/g wet weight) and bulls (111 +/- 2 pg/g wet weight) contained oxytocin but at much lower concentrations compared to corpus luteum tissue. About 10 times higher concentrations of oxytocin were measured in the adrenal medulla (717 +/- 96 pg/g wet weight) compared to the cortex (72 +/- 11 pg/g wet weight). Seminal vesicles and prostate gland contained no measurable amounts of oxytocin (less than 5 pg/g wet weight).

Abstract
During the last few years, a relative increase in the number of patients with non-puerperal mastitis was recorded. From 1980 to 1983, 51 patients were treated who were suffering from an abacterially or bacterially complicated nonpuerperal inflammation of the breast tissue. The present paper reports on patients' history, clinical symptoms, and the development of this form of mastitis during different methods of treatment. The importance of pre-existing lesions of the breast tissue and of hormonal data for the pathogenesis is discussed. The authors conclude that the administration of prolactin inhibiting drugs is an effective therapy. This treatment results in lower rates of abscesses. Long-term therapy with bromocryptine can prevent recurrence of this disease.
