[Muscarinic receptors on lymphocytes].

Introduction: The presence of muscarinic receptors on lymphocytes and possible modifications in their number and affinity may be related to cholinergic changes found in muscarinic receptors at a central level.

Objective: The objective of this paper is to bring the technique for the determination of lymphocyte muscarinic receptors by means of their union with radioligands for application in the study of disorders involving the cholinergic system, such as Alzheimer's disease, up to date.

Material And Methods: We therefore made a density gradient isolation of lymphocytes from healthy subjects and made a trial of union or binding with N-methyl-escopolamine marked with tritium (3H-NMS) on intact lymphocytes.

[Antiphospholipid antibodies and neurological disorders. Types and mechanisms].

The antiphospholipid antibodies (AAFL) are acquired antibodies of different types whose common characteristic is that they are directed against the negatively and neutrally charged phospholipids of the cell membranes. They were first described in 1952 in patients with systemic lupus erythematosus. They are also found in many pathological conditions such as: infections, solid and haematological neoplasms, chronic renal insufficiency, primary immunological deficiencies and other collagenoses, hepatobiliary diseases, etc.

[Hormonal markers of stress in acute cerebrovascular pathology].

Various studies carried out over the last decade have shown that high glucose levels in the blood foster ischaemic brain damage associated with a worse evolution of such pathologies. The aim of the study we performed was to try to shed some light on whether stress in these patients raised their glucose levels adding to a worsening of the patient's clinical picture. We studied 318 consecutive patients suffering from stroke.

[Descriptive epidemiology of risk factors in cerebrovascular disorders:a study in Muro d'Alcoi].

We evaluated cerebrovascular risk factors and the values of cholesterol and triglicerides in the survey in Muro d'Alcoi using a door-to-door randomised interview. We found 14.9% hypertensives, 5.

[Determination of basal GH in dementias].

We have studied the plasmatic levels of the growth hormone (GH) in a control group consisting of 72 subjects with an average age of 69.7 +/- 8.4 years and in a group of 37 patients with an average age of 69.
