Since phenotypic manifestations are similar in most families, classification is based on differences in the mode of inheritance, onset and progression of the disease, nerve conduction velocity and nerve biopsy findings. Autosomal dominant, autosomal recessive, X-dominant and X-recessive forms, substantial intrafamilial differences, intermediate forms and the combination of neuropathies with spinocerebellar degeneration within one and the same sibship have been described. On the basis of selected own cases it is demonstrated that there is a broad spectrum of functional and structural abnormalities depending on the progression of the disease and on the site of nerve studied (proximal or distal part). Both the neuronal and hypertrophic variants begin with axonal degeneration of the dying back type followed by segmental demyelination and variable degrees of hypertrophic Schwann cell proliferation. Constantly, posterior columns of the spinal cord reveal fiber loss. Since the molecular basis of the different forms remains to be clarified it seems to be of greater interest to underline common features than to separate seemingly different nosological entities. It is suggested that the latter are partly the result of a selection of cases with a variable severity. Evidently, the syndrome of myatrophic ataxia comprises apart from \"pure\" HMSN with unsignificant degenerations of posterior columns and \"pure\" Friedreich's ataxia with mild peripheral nerve fiber loss intermediate forms.</p>","PeriodicalId":23840,"journal":{"name":"Zentralblatt fur allgemeine Pathologie u. pathologische Anatomie","volume":"136 6","pages":"549-62"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13431846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lesions caused by these experimentally established pathological conditions were analysed by the following criteria, after treatment with a Ca-blocking agent (Nitrendipine, Bayer, Leverkusen): Changes in systematic blood pressure; Histochemical detectability of myocardial and vascular lesions as a consequence of artificially induced hypertension and hypoxaemia; Assessment by means of the tracer technique (Ferrlecit, Nattermann, Cologne) of alterations to vascular permeability in small cardiac vessels of rats treated and not treated with the Ca-blocking agent; Detection of lesions in small vessels of other organs, such as intestine, mesentery, and pancreas, in rats treated and not treated with the Ca-blocking agent. This study has been conducted for the purpose of elucidating vascular lesions resulting from lasting hypertension and short-term hypoxaemia, with particular attention being given to effects of therapeutic intervention on morphological expression of vascular damage. The Ca-blocking agent had a favourable effect on vascular alterations due to long-term and short-term injuries, since the animals treated with Nitrendipine exhibited drop in blood pressure and developed very mild vascular lesions, if any. The cardioprotective action of Nitrendipine was readily obvious under the above experimental conditions.</p>","PeriodicalId":23840,"journal":{"name":"Zentralblatt fur allgemeine Pathologie u. pathologische Anatomie","volume":"136 1-2","pages":"97-111"},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13478424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence was produced to the existence of syncytial bridges between neighbouring chorionic villi. Besides, syncytial knots and sprouts were present, as well as structures apparently similar to bridges which had resulted from peculiar cutting through a syncytial knot. The latter have been referred to as artefacts by other authors and are obtainable only under two conditions: 1. pre-existence of nuclear agglomeration at cutting level; 2. accidentally appropriate cutting. Such coincidence has been recordable from two thirds of all cases, but it is by no means responsible for all cases of bridge formation. Structures of that kind are never artefacts by any account of lexical meaning. The following criteria are suggested for differentiation between bridges, on the one hand, and structures resembling bridges due to tangential sections: 1.

Classification was conducted according to recommendations given by a working group of pathologists, specialised in liver pathology. 42 cases out of this material had come from Prenzlauer-Berg Hospital, Department of Infectious Diseases, and were re-examined under clinical aspects. 6 of them were discarded from evaluation. Type I proved to be of high diagnostic reliability, as was seen from 61% of all cases. Only 3 cases had to be discarded from that group and were associated with other drugs, such as halothane, methyldopa, and propranolol. The following clinical parameters proved to be of particular value for definite assessment of drug-induced hepatitis: time of exposure (for analysis of co-medication), time of recovery, and re-exposure test. Only circumstantial evidence so far can be provided for all histological types to causative relationship between drug ingestion and hepatitis.
