Abstract
Low density lipoproteins (LDL) are considered to be the most atherogenic of lipoproteins. These LDL can be modified and oxidative modifications are now well known. In addition, other atherogenic modifications of LDL exist, such as desialylation. In the present study sialic acid content was determined in LDL preparations obtained from patients with coronary artery disease (CAD+) and compared with that of healthy subjects and patients without coronary heart disease (CAD-). The sialic acid concentration was found to be statistically lower (P < 0.05) in the LDL of CAD+ patients (11.6 +/- 2.7 micrograms/mg of protein) than in the LDL of controls (16.5 +/- 5.6 micrograms/mg of protein) or in the LDL of CAD- patients (15.3 +/- 3.8 micrograms/mg of protein). In subgroups of CAD+ patients divided according to the severity of the disease, no statistically significant difference was observed in LDL sialic acid content. This work confirms the presence of desialylated LDL in the sera of patients with atheroma.

Abstract
Malondialdehyde, a marker of lipid peroxidation, was measured as thiobarbituric acid reactive substances (TBARS) in 117 diabetic patients and 53 controls. Patients were divided into groups and subgroups according to the type of diabetes (type 1 and type 2) and the existence or not of vascular complication (macro- or micro-angiopathy). Results showed that TBARS concentrations were significantly higher in type 1 (P < 0.0001) and type 2 (P < 0.001) diabetic patients than in the control group. The plasma TBARS concentrations in type 1 and type 2 diabetic patients did not differ significantly. Among the patients with vascular disease, type 2 diabetic patients with macroangiopathy had significantly higher TBARS concentrations than patients with no vascular complication (P < 0.05). Whichever the type of diabetes, there was no correlation between TBARS concentrations and glycaemic control: glycosylated haemoglobin, fasting blood glucose. This study confirmed the existence of lipid peroxidation disorders in diabetic patients.

Abstract
A macrocreatine-kinase type 1 was identified by CK isoenzyme electrophoresis of a serum sample from a patient. Constituents of this enzyme complex were studied. The isoenzyme present in the macrocreatine-kinase was identified using immunoprecipitation with antibodies against the M subunit. Affinity chromatography then determined the type of the immunoglobulin bound to the CK isoenzyme. A protocol for studying macrocreatine-kinase type 1 compounds is proposed.

Abstract
Six biochemical parameters and four enzyme activities were determined from the serum of 76 healthy and 56 pathological human fetuses between the 20th and 38th week of pregnancy. In the normal fetuses studied within that period, creatinine, immunoglobulin M, lactate dehydrogenase, and gamma-glutamyltransferase increased; haemoglobin F and glucose progressively decreased; and alkaline phosphatase was at a peak around the 26th week; cholesterol and triglycerides were always low. The same parameters were also measured in some of the pathological fetuses and compared with their normal counterparts.

Abstract
Concentrations of alpha 1 acid glycoprotein, albumin, transferrin, haptoglobin, immunoglobulins G, A, M and apolipoprotein B were measured in serum and suction blister fluid from a group of individuals presenting a biologically proven inflammatory syndrome, and from a control group. Protein values in suction blister fluid did not change from the 2nd to the 3rd h after the beginning of blister formation. The ratio of the concentration of proteins in blister fluid and serum did not differ significantly between the groups. However, a 25% decrease in blister fluid albumin and a 100% increase in blister fluid alpha 1 acid glycoprotein, recorded in the inflammatory group, were worth noting, since they possibly influence the tissular distribution of some protein-binding drugs. Finally, an inverse relationship was established between the blister fluid/serum concentration ratio and the respective molar mass of each protein.

Abstract
Six-hundred sixty-seven patients with endoscopically proven peptic ulcer were included in a randomized, multicenter trial to assess the comparative efficacy of sucralfate and cimetidine. One hundred eighty-seven patients with gastric ulcer and 480 patients with duodenal ulcer completed the study. Ulcer healing was evaluated endoscopically at six weeks for duodenal ulcer and at eight weeks for gastric ulcer. Patients with unhealed ulcer at this time were assigned to the other therapy for a second period of six or eight weeks of treatment (crossover). In patients with duodenal gastric ulcer, pain relief and healing were not significantly different in the two groups. Eighty-eight percent of duodenal ulcers and 73 percent of gastric ulcers healed with six weeks of sucralfate treatment. Reported side effects and symptoms, pooled together for duodenal and gastric ulcer, were more significant in the sucralfate group (7.5 percent) than in the cimetidine group (3.7 percent). Constipation was the most frequent symptom recorded. In conclusion, sucralfate and cimetidine are both excellent healing agents for short-term treatment of duodenal and gastric ulcer. Both give rapid relief of symptoms without severe side effects.

Abstract
We report a case of amodiaquine-induced agranulocytosis in a 60-year-old woman. Four months after the agranulocytosis episode we investigated the effect of the drug using in vitro agar culture techniques. Amodiaquine at increasing concentrations (0.005, 0.05 and 0.5 microgram/ml) displayed an inhibitory effect, probably dose-dependent, on the growth of the patient's bone marrow GM-CFU colonies in the absence of autologous serum. In contrast, no effect was found on the colony and cluster growth of bone marrow samples from 13 healthy controls. Though it has been shown in several cases that amodiaquine-induced agranulocytosis occurs via immune-mediated mechanisms, our data are in support of a direct toxic effect of the drug on abnormally sensitive myeloid progenitor cells.

Abstract
HPA-23 is a competitive inhibitor of the RNA-dependent DNA polymerase (reverse transcriptase) of the human immunodeficiency virus (HIV). It may therefore potentially benefit patients with HIV infection. This study aimed at defining the haematopoietic toxicity of this drug and particularly its effects on the normal human granulocyte-macrophage progenitor cells (GM-CFU). Our in vitro studies, in semi-solid agar, have shown an inhibitory effect of increasing concentrations of HPA-23 on colony and cluster formation. This effect is probably dose-dependent. An almost complete inhibition of colony formation was observed at doses of more than 20 micrograms/ml. Regarding cluster formation, a similar although much more progressive inhibitory effect was found. Our experimental data should be extrapolated with caution to clinical situations. However, they must be kept in mind for optimal design of HPA-23 therapy in HIV infected patients.

Abstract
Plasma fibronectin was determined by laser nephelometric immunoassay in two populations: healthy individuals and patients with metastatic or non-metastatic breast cancer. The results showed that the fibronectin concentration was higher in the patient group than in the healthy controls of similar age, with a significant difference (p less than 0.05). The patients who had metastatic breast cancer tended to show higher levels than those with no detectable metastasis, but such a difference was not statistically significant. Since fibronectin is sensitive to clinical events unrelated to the malignancy status, it does not seem suitable as a tumor marker.

Abstract
Many medical decision helping systems are very complex and require expensive computers, which restricts their diffusion and limits their use to specialized people. The idea was to find a simplified system that any practitioner--even unaccustomed to microcomputing--would be able to use. Moreover, this system had to work on widely available and inexpensive microcomputers. SELF (system in fuzzy set) is this kind of system. It has been devised as a complete interactive system of medical decision help. It is entirely parameterized, allows any kind of application and works according to such rules as "if there is premise, then there is conclusion", tempered by a coefficient. The bases of knowledge are represented on a correspondence chart where columns materialize the premises (clinical signs, laboratory results, etc.) and horizontal lines all the diagnoses and therapeutic conclusions. The system includes proceedings that create, modify and update basic knowledge. It uses the fuzzy set rules to draw conclusions. SELF was first applied to the prescription of contraceptive methods, but it has now been tested in other specialties, such as gynaecology, pneumology, haematology and so forth. In every case, the reliability of the results obtained depends on the bases chosen by the creator himself. Owing to the general character of the system, one may regard it as being open to any user who would like to create his own applications.
