[RARE-MR myelography in routine clinical practice. Experience with 175 cases].

In 1984 Henning, Nauerth, Friedburg and Ratzel described a new MRI data acquisition technique called RARE (Rapid Acquisition with Relaxation Enhancement). Several clinical applications have been published. A modification developed in the meantime, called "RARE hydrography", yields T2-weighted aqueous fluid specific images within a few seconds. As a nontomographic rapid approach to MR-myelography ("RARE-myelography") this technique is routinely applied at the beginning of all examinations of the spine. On the basis of 175 cases current potentials and limitations are discussed. Future applications of 3D-RARE myelography are mentioned.

Five-and-a-half years' experience with percutaneous retrogasserian glycerol rhizotomy in treatment of trigeminal neuralgia.

The results of treating trigeminal neuralgia with percutaneous retroganglionic glycerol rhizotomy in 319 patients from an overall series of 394 patients with 459 operations carried out over a period of 5 1/2 years are reported. Idiopathic trigeminal neuralgia was the diagnosis in 252 patients. 34 patients had trigeminal neuralgia associated with multiple sclerosis. The remaining 33 patients suffered from symptomatic trigeminal neuralgia or atypical facial pain. 230 patients (91.3%) with idiopathic trigeminal neuralgia and 30 patients (88.2%) with multiple sclerosis reported complete freedom from pain. In 12 patients (4.8%) of those with tic douloureux and in 1 patient (2.9%) with multiple sclerosis, pain was alleviated, and the patients required a reduced pharmacotherapy. 10 patients (3.9%) and 3 patients (8.8%) were considered to be treatment failures. The rate of recurrences within the first 2 years was 10.9 and 40.0%, respectively. In the long-term, the rate of recurrences in patients with tic douloureux was 36.9%. 144 patients (45.1%) noticed a hypesthesia. 132 patients (41.4%) had hypalgesia following the procedure, and there was a decrease of symptoms in the long-term observation in 20.0% of the patients. 59 patients (18.5%) developed dysesthesia postoperatively which regressed only to an inappreciable extent in the long-term course. In 16 patients (5.0%) exclusively with a preexisting organic lesion or who had received surgical pretreatment, there was a loss of corneal sensation. The investigation showed on the one hand the effectiveness of the method, but on the other hand also the possibility of marked sensory disorder in selected cases.

Polyethylene glycol-mediated infection with avian sarcoma viruses.

In this communication we report that fusion of viral and cellular membranes by polyethylene glycol is a convenient approach to overcoming genetically determined resistance to infection. Using this method, avian sarcoma virus-transformed mammalian cells have been produced which serve as useful model systems for the study of Rous sarcoma virus-specific tumor antigens.

Immunodiffusion studies on Schistosoma mansoni and its host stage specific antigens. 1. Immunoelectrophoresis cross-reactions between S. mansoni adults and larval stages antigens.

IMMUNOELECTROPHORESIS was applied to evaluate the immunologic relationship between the different stages in the life cycle of Schistosoma mansoni (S.m.). The preparation of antigens and antisera was described. Separated female and male adult worms tested seem to be identical. Eggs, miracidia and cercariae from Biomphalaria glabrata and Biomphalaria alexandrina showed varying degree of cross-reactions. The maximal number of pricipitin arcs was observed, when anti-miracidia-serum was checked against all other S.m. antigens.

Immunodiffusion studies on Schistosoma mansoni and its host stage specific antigens. 2. Immunoelectrophoresis cross-reactions between hepato-pancreas of Biomphalaria glabrata and Biomphalaria alexandrina.

IMMUNOELECTROPHORESIS was used for studies on immunological cross-reactions between both Schistosoma mansoni (S. m.) intermediate host snails Biomphalaria glabrata and Biomphalaria alexandrina. The preparation of antigens and their corresponding antisera from hepato-pancreas of S. m. infected and non infected snails was described as the homologous reactions of both snails either infected or non infected were rather similar, close immunological relationship between B. glabrata and B. alexandrina could be deduced.

Immunodiffusion studies on Schistosoma mansoni and its intermediate host stage specific antigens. 3. Immunoelectrophoresis cross-reactions between S. mansoni stages and Biomphalaria sp. hepato-pancreas antigens.

IMMUNOELECTROPHORESIS was applied for cross-wise checking of the different stages in the life cycle of schistosoma mansoni with extracts of hepato-pancreas from its intermediate host snails Biomphalaria glabrata and Biomphalaria alexandrina. Only few fractions were common to non infected snail organ and parasite development stage, while more crossreactions were detected with infected snail hepato - pancreas.

Influence of diet on breeding and infectivity in mass cultivation of Biomphalaria glabrata.

Under well defined laboratory conditions as troughs, room temperature, humidity, water and air supply Biomphalaria glabrata was bred and kept. In feeding trials powder of pellets for mice and commercial fish food were used as high protein diet in comparison to poor protein diet consisting of lettuce only. The high protein diet resulted in more clutches and eggs per snail than the lettuce diet. Also the yield of cercariae in the rish protein group was much higher than in the group fed on on lettuce alone. The optimal amount of snails could be obtained by feeding pellet powder, fish food and lettuce.

Influence of diet on breeding and infectivity in mass cultivation of Bulinus truncatus.

Under well defined laboratory conditions as troughs, room temperature, humidity, water, and air supply Bulinus truncatus was bred and kept. In a feeding trial high protein diet consisting of powdered mice pellets, commercial tropical fish food and lettuce was compared to poor protein diet of lettuce alone. Higher yield of clutches, eggs and cercariae were observed in the rich protein diet group, Bulinus and Biomphalaria Snail seem to be influenced by diet in the same way.
