    Notizen: Summary The purpose of this article is to present detailed data on the nutritional assessment in cirrhotic patients. The exact frequency and types of malnutrition, its associations with the aetiology of liver disease, liver dysfunction and clinical staging in liver cirrhosis are unknown. A new classification system is presented which may help to suggest some interventional guidelines. Physical (anthropometry, 24-h urinary creatinine excretion, bioelectrical impedance analysis (BIA), total body potassium counting, ultrasound examination) and metabolic (indirect calorimetry) assessment of nutritional status was therefore performed in 123 patients with liver cirrhosis, who were considered as potential candidates for liver transplantation. Data were related to the clinical, biochemical, histological and prognostic data of liver disease. Of our patients 65% showed some signs of protein-calorie malnutrition as indicated by low body cell mass, reduced serum albumin concentrations or abnormal skinfold thickness. Of these 34% were considered as “kwashiorkor-like” (normal body composition, serum albumin 〈35 g/1), and 18% were “marastic” (reduced body weight, body cell mass, and fat mass). However, 49% of the malnourished group had reduced body cell mass in association with increased fat mass and frequently presented with a normal body weight (“mixed” or “obese” type). Protein-calorie malnutrition did not correlate with the aetiology of the disease and biochemical parameters of liver function. Malnutrition was observed at all clinical stages but was more frequently seen at advanced stages. We conclude that malnutrition associated with liver cirrhosis is not a clear phenomenon. Its clinical presentation is heterogenous and not reflected by the histological or biochemical parameters of liver disease. Since malnutrition is rarely diagnosed, early and detailed nutritional assessment in all patients with liver disease is important.

    Notizen: Summary The complex catecholaminergic (CA) nervous system of the polychaete Ophryotrocha puerilis is documented using glyoxylic acid induced fluorescence (GIF) and immunohistochemistry. CA-neurons are found both in the central and peripheral nervous system. In the brain, about 50 CA-neurons are present in the perikaryal layer together with numerous CA fibres. Two pairs of CA perikarya are characteristic for each ganglion of the ventral nerve cord. CA-neurites in the ventral nerve cord are mainly arranged in 4 strands paralleling the longitudinal axis of the worm. Fluorescent neurons with receptive ciliary structures are present in body appendages (antennae, palps, urites, parapodial cirri), in the body-wall, and within the oesophageal wall. Furthermore, a subepidermal nerve net of free CA nerve endings has been found. After incubation of specimens with dopamine prior to the development of GIF more fluorescent perikarya could be observed; the fluorescence was also intensified. Pre-incubation with reserpine reduced the intensity of GIF. Results of high pressure liquid chromatography and immunostaining with a polyclonal antibody against a dopamine-glutaraldehyde-complex suggest that dopamine is the major CA transmitter. It is thought that dopaminergic neurons together with ciliary receptive structures act as mechano- and/or chemoreceptors.

    Notizen: Summary In the posterior part of the brain of the protandric polychaete Ophryotrocha puerilis neurosecretory cells form prominent axon terminals. The terminals are arranged in two complexes. The perikarya of these presumably monopolar neurons are scattered in the anterior part of the cerebral perikaryal layer. In females the terminals store large amounts of neurosecretory material. It has been suggested earlier that neurosecretions of the terminals may play a role during sex reversal from females to males. Application of histamine caused the release of neurosecretory material from the respective terminals in females. However, this discharge was not followed by sex reversal. Application of reserpine had no influence on the terminals. Neither by in vivo observation nor by ultrastructural analysis any effect of reserpine on the terminal complexes could be observed. In isolated terminals filled with neurosecretory material from females, catecholamines could not be detected by HPLC. Also, polyclonal antibodies against dopamine did not stain the terminal complexes. Furthermore, the complexes did not develop any fluorescence after glyoxylic acid treatment. Therefore, the present results contradict the hypothesis that the neurosecretory material of the respective axon terminals is catecholaminergic and that it is involved in sex differentiation. The function of the secretory neurons studied here remains unclear.
