The authors explored a group of patients suffering from rheumatic pelvispondylitis from the point of view of muscular lesions: clinical muscular examination, anatomo-pathological investigation of the muscle (optical microscopy, histochemistry), electromyographic investigation, and determination of certain serum and muscle enzymes. Some muscular anomalies were observed, which were predominant in the muscles of the lumbar grooves, although there were some lesions of the quadriceps muscle, with a myogenous appearance, but without inflammation. The clearest anomalies were neurogenic and were present particularly in the muscles of the lumbar grooves.

[Amyotrophy and neuronal depopulation of cerebral origin].

Amyotrophy of cerebral origin was analyzed in 12 hemiplegics by means of comparative histological, histoenzymological, histographic and biochemical analysis of biopsies carried out in symmetrical zones. In the 6 cases in which atrophy predominated on the paralyzed side, it occurred early, the deficiency affecting the upper limb in particular and the sensory disturbance being irregular. Attempted numeration of the motor units remaining, according to the "incremential" method of stimulation, suggests a numerical reduction on the hemipelgic side. Despite reservations and general criticisms of this method, its comparative value, although approximate, must be acknowledged. However, although amyotrophy presumes a transsynaptic change in trophic function to have taken place in the peripheral neurone, neuronal depopulation--if one accepts it--cannot be other than functional.

[HL-A and Paget's disease].

In a study on 43 patients suffering from Paget's disease the authors grouped them within the HL-A histo-compatibility system. Twenty-nine antigens in this system were investigated. Comparison with the distribution in the population of France did not show a significant difference. Nevertheless, there appeared to be a greater frequency of the HL-A 5 and perhaps of W 22 antigens in patients suffering from generalized Paget's disease.

[Irregular agglutinins, hemolysins, antilymphocyte antibodies, serum anticomplementarity, human and species antiglobulins and cryoglobulins in a series of 33 patients with rheumatoid arthritis].

An immunological investigation was carried out on 33 rheumatoid polyarthritis patients. The phenomena of antierythrocytes immunization were investigated by standard tests : irregular agglutinins, haemolysins, and auto-antibodies which all proved negative. The lymphocyte immunological phenomena were also studied. Cold (4 degrees C) lymphocytotoxins were shown in 8 patients, 5 of whom had anti-lymphocyte auto-antibodies. The proportions of "sheep rosettes" were significantly reduced. The sera did not show notable anti-complementary activity. Studies on the human antiglobulins and on species antiglobulins were not very conclusive. Cryoglobulins were never detected. No clear correlation was found between these different tests and those of standard rheumatism serology.
