[Psychosis and grammatical reality. Preliminary to an axiomatic system].

This paper is elaborated in the same order of those who developpe the idea that, Psychosis is pleaded as an alibi of a totalitarian reality (Psychosis alibi). So it may allow to disengage the evolution of the Psychiatry outside of the anti-psychiatry ideologies. The main subject of this work, is to analyse the gap between the Reality which includes the psychosis as a part of herself (Psychosis as disease). On the second hand the Reality of the psychosis from the psycho-pathologic point of view (delirium, hallucinations, autism, etc...). Considering the importance of the formal grammatical functions in the linguistic matter to site the reference to the reality according to the rules of the communication and the oral expression; so we propose a grammatical analysis. Two parts are distinguishable in this work. The first part concerns a review of languages proposed in different psychiatric "theorization" established previously about mental disorder. So it could be considered that the psychosis is the one who "speaks" the psychiatry. The second part concerns an abstract of the "semiotiques" studies by which we can tackle the psychosis with a scientific language: The Psychiatric "speaking" the psychosis not the opposite. This way of analyse allows to realize the modifications in the part of both protagonists in the game. By the same way, it authorizes to introduce the psychiatry from the axiomatic point of view, allowing a self-contained definition as a branch of the medicine, and disengaging his subject: The psychosis; as a syntactic subject.

[Pharmacokinetics of trimethoprim and sulfametrol in patients with end stage renal failure and hemodialysis treatment (author's transl)].

In 6 patients with regular dialysis treatment the pharmacokinetics of intravenously administered trimethoprim and sulfametrol were investigated not only during dialysis procedure but also during the dialysis-free interval. Half-life of the free plasma sulfametrol component is normal even in cases with absent renal function and can be markedly reduced by hemodialysis treatment. The N4-acetylated main metabolite of the sulfonamide is - similar to trimethoprim - hardly dialyzable. Half-life of the latter drug component is prolonged in patients with far advanced renal failure. Due to the excellent dialysanceof the free plasma sulfonamide component the elimination of total sulfametrol is normal during hemodialysis despite cumulation of the N4-acetylated metabolite. Because of the tendency of this metabolite to cumulation, in dialysis patients the compound preparation of trimethoprim and sulfametrol should be used only for trasient treatment of acute infections.

Angiotensin-converting enzyme in uveitis and sarcoidosis.

Serum angiotensin-converting enzyme (SACE) was studied in a group of 29 sarcoidosis patients (among whom five had uveitis) and in 22 patients with non-sarcoid uveitis. SACE was normal in all non-sarcoid patients and elevated in 62 per cent of the patients with sarcoidosis. Thus an elevated SACE is closely linked to sarcoidosis and may be a valuable tool in evaluating patients with uveitis in search of a sarcoid origin.

[Alpha 1-antitrypsin level in serum of dialyzed and renal transplant patients (author's transl)].

alpha 1-Antitrypsin in serum was determined by radial immunodiffusion in 30 healthy persons, 18 dialyzed patients and 11 renal transplant recipients with an observation time up to 24 months after surgery. There was no significant difference in serum alpha 1-antitrypsin concentrations in dialyzed patients when compared to the controls (2570 +/- 570 and 2280 +/- 450 mg/l respectively). alpha 1-Antitrypsin concentration increased significantly from the first day after successful renal transplantation, then decreased again 10 days thereafter. Long term follow up controls 3, 6, 12, 18 and 24 months respectively after surgery--with a good renal transplant function--revealed values within the normal range. An acute rejection episode of the transplant was connected with a significant increase of alpha 1-antitrypsin concentration in the serum. Determination of alpha 1-antitrypsin level in serum can be useful in the diagnosis and prognosis of acute renal transplant rejection.

Persistent pituitary-thyroid dysfunction patients following renal transplantation.

Pituitary-thyroid function, which is known to be altered in patients with chronic renal insufficiency, has been evaluated after successful kidney transplantation in 36 patients and compared with that in 15 healthy subjects. Thyrotropin (TSH) response to thyrotropin-releasing hormone (TRH) was in the low range of normal in 24, and markedly decreased in 12 patients (< 0.0005). In the former group serum thyroxine was normal, whereas triiodothyronine was lowered; in the latter group thyroxine, although within the normal range, and triiodothyronine levels were reduced when compared with that of healthy controls. This differential TSH response to TRH was unrelated to kidney transplant function, duration of renal insufficiency or duration of the preceding hemodialysis, or to the dose and dosing schedule of prednisolone therapy. However, a slight negative correlation between the dose of prednisolone administered and TSh responsiveness to TRH as well as serum triiodothyronine was established (P < 0.05). Thus, corticoid treatment may in part be responsible for the alteration in TSH secretion and in the peripheral conversion of thyroxine to triiodothyronine. Other, as yet undefined factors, such as patients' variability in pituitary susceptibility to the polypragmatic therapy administered, have to be suspected as the major causes of the persistent pathological pituitary-thyroid function tests observed after renal transplantation.

Combined action of hepatotoxic substances and increased environmental temperature on the liver of rats.

Male albino rats were orally treated in a single dose with 40 mg allyl alcohol/kg or 50 mg 4,4'-methylenedianilline/kg, or 100 mg 1,1,2,2-tetrachloroethane/kg, or 400 mg carbon tetrachloride/kg, or 800 mg chloroforme/kg, immediately after-wards exposed to increased temperature (35 degrees C, 50% RH, 4 h), and examined 20--22 hours later. Under these conditions, only carbon tetrachloride led to a more intensified changes manifesting themselves in changes of the serum enzymes LAP, ALAT, and GLDH, as well as in liver histology. The liver lesions, caused by the substances mentioned, reacted to an additional thermal strain in a comparable manner as the LD50-values determined under identical exposure conditions. The temperature-dependent enhancement of the carbon tetrachloride hepatotoxicity is ascribed to an intensification of liver peroxidation processes due to increased core temperature.
