Inosiplex, a stimulating agent for normal human T cells and human leukocytes.

The influence of inosiplex upon various in vitro leucocyte assays was studied in normal individuals. It was found that the drug increases the response of bidirectional and unidirectional mixed lymphocyte cultures at concentrations of 200, 300, and 500 microgram/ml. It also significantly increases the percentage of active T rosettes (concentration range: 50 to 500 microgram/ml) and the percentage of autologous red cell T rosettes (concentration: 100 microgram/ml). In contrast, inosiplex did not modify the percentage of total T rosettes and EAC rosettes. Inosiplex increases the number of nonadherent leucocytes in the leucocyte adherence inhibition test at a concentration range between 100 and 300 microgram/ml. Finally, inosiplex also increases the percentage of monocytes phagocytizing yeast at a concentration between 50 and 500 microgram/ml. These data indicate that inosiplex enhances the function of normal human T cells, monocytes, and possibly neutrophils. Therefore inosiplex appears to have immunostimulant properties.

[Sharp's syndrome: a new entity amongst the connective tissue diseases?].

Sharp and coworkers have coined the name "Mixed connective tissue disease" to an association of symptoms seen in different connective tissue diseases. Those symptoms are associated with a special antibody directed against ribonucleoproteins (RNA-P). The presence of this antibody accounts for a high titer of antinuclear fluorescent antibody, of the speckled type. The most frequents symptoms in the association described by Sharp are Raynaud's phenomenon, swollen fingers, non deforming arthritis. We have observed those symptoms without any further symptoms of connective tissue disease, but with the presence of anti-RNA-P antibody. We suggest to coin the name of Sharp's syndrome to that clinical association. The significance of anti-RNA-P, and their correlation with a remarkable benignity of the disease, is discussed.

Comparison of the onset and intensity of action of intramuscular meloxicam and oral meloxicam in patients with acute sciatica.

In this randomized, double-blind, double-dummy trial, 113 patients with acute sciatica were treated with a single 15-mg dose of meloxicam given intramuscularly (n = 54) or orally (n = 59). There was a significant improvement in induced pain (as measured by using the straight-leg-raising test) in both treatment groups at 60 minutes (P < 0.005), and there was a significant difference in favor of the intramuscular formulation in terms of the time to maximum improvement of induced pain (P = 0.01). Changes in spontaneous pain were similar in both treatment groups and were significant versus baseline (P < 0.01) at 30 minutes after study drug administration. Global efficacy evaluations by both the patients and investigators confirmed that meloxicam 15 mg in an intramuscular or oral formulation was effective in relieving pain in patients with acute sciatica. Meloxicam was generally well tolerated, and the local tolerability of the intramuscular injection was found to be excellent on the basis of both clinical evaluation and assessment of creatine phosphokinase levels.

Sport and medicine in ancient Greece.

Sport and medicine in ancient Greece were the result of a widespread tradition of liberty, which was at the heart of one of the most brilliant civilizations in history. Whereas war encouraged the development of surgical knowledge springing out of medical experience on the battlefield, peace promoted the burgeoning of sport as an integral part of Greek upbringing, allowing the channeling of young people's aggressiveness into physical competition. Medicine was magical and mythological, especially in the time of Homer (9th century BC); Aesculapius, the mythical god of healing, was its reference point. With Hippocrates (5th century BC), the body of medical experience was to be codified and built up, and was to undergo a novel evolution based on the theory of the balance of the four humors. The athlete's mentality, faced with trauma in the sports ground, underwent a change; injury was no longer considered a punishment by the gods. At the same time, temple offerings tendered in the hope of victory gave way to the athlete's personal preparation based on a specifically modified lifestyle, diet, and training. The resulting progress in medicine and public health, especially from the 5th century BC onward, was not only to favor athletic performances of high quality but also surgical techniques that were very advanced for their time. Thus it can be seen that the medical knowledge associated with the practice of sport progressed during antiquity because of its obligation to follow the warrior and then the athlete.

Sialic acid residues in the labial salivary glands from Sjögren's syndrome patients.

OBJECTIVE: To investigate the composition and expression of sialic acid in the labial salivary glands (LSG) in Sjögren's syndrome (SS). METHODS: LSG of 19 patients with primary SS (n = 11) or secondary SS (n = 8) were studied. Specimens from 7 healthy women served as controls. Computer-assisted microscopy was employed to quantitatively determine the percentage of positive structures, the staining intensity and the heterogeneity for the 4 biotinylated plant lectins Tritricum vulgaris L. (WGA), Maackia amurensis (MAA), Sambucus nigra (SNA) and Canavalia ensiformis L. (Con A). RESULTS: In the acini there was a significant decrease in the staining heterogeneity of WGA in SS compared to controls; the same was observed with respect to MAA staining in the connective tissue and extralobular ducts. In the intralobular ducts, primary SS differed from normal and secondary SS mainly in terms of a decrease in the percentage of positively labeled MAA tissue. In addition, Con A stained acinar cells were significantly more numerous in secondary SS compared with primary SS. CONCLUSION: Differences in the degree of glycoconjugate sialylation were found in SS labial salivary glands, and may play a role in the disease process.
