The pneumococcus is now the most important bacterial pathogen causing pneumonia, meningitis, and otitis media. Traditional approaches to the diagnosis of Streptococcus pneumoniae as the etrologic agent causing these diseases include colony morphology, microscopy, optochin sensitivity, bile solubility, and inmunologic reaction with type-specific antisera(1) The rationale for developing a molecular approach to diagnosis mcludes the very low yield of pneumococci isolated from blood culture in presumed pneumococcal pneumonia, and the need for a rapid diagnostic test that defines susceptibility to antbiotrcs, partxularly in the setting of meningitis...

Hansen's disease presents a wide spectrum of clinical and histopathological manifestations that reflect the nature of the immunological response of the host towards diverse Mycobacterium leprae components. The immunological system, composed by both innate and adaptive immunology, offers protection towards infections of various etiologies, among them bacterial. Bacteria, of course, have developed multiple strategies for evading host defenses, based on either very complex or simple mechanisms, but with a single purpose: to "resist" host attacks and to be able to survive...

Basiliximab induction treatment has been shown to reduce the incidence of acute rejection episodes without the secondary side effects observed with antilymphocyte polyclonal antibodies. We analyzed our experience with basiliximab induction associated with tacrolimus-based immunosuppression among low-immunological risk renal transplant recipients. We retrospectively analyzed 55 renal transplantation patients of low inmunological risk who received organs from donors younger than 55 years. We compared a group of 21 patients (38...

After mentioning the importance of implementing these techniques, frecuently used both in USA and Spain, he refers to his experience on 70 dogs since the end of the 50's in the last century. Not only does he refer to the heterotopic transplant, on the neck, undertaken to test the importance of the denervation, maintenance of the viability of the organ using hypothermia, and the anatomopathologic study of the inmunologic rejection, but also to the orthotopic transplant, this is the replacement of one heart by other, using extracorporeal circulation...

Superficial mycoses are considered to affect more frequently patients with type 2 diabetes mellitus (DM-2), specially onychomycosis and Tinea pedis. The purpose of this study was to compare the dermatophytoses, candidiasis and Pitiriasis versicolor frequency between 40 patients with DM-2 and 40 healthy persons of either sex, 40 years old or more. Clinical, metabolic, mycologic and inmunologic studies against Candida albicans, were carried out. Both diabetics 75% (30/40) and controls 65% (26/40) presented a high frequency of superficial mycoses (no significant difference p = 0...

There is great evidence that both gastric lymphoma andadenocarcinoma are related in their pathogenesis to Helicobacter pylori infection.It has been stablished that mucosa associated lymphoid tissue (MALT) is anacquired condition following H. pylorl infection and that B cell gastriclymphoma derives from this cell linage. Low grade MALT lymphoma transformsto high grade lymphoma. Furthermore, MALT B cell lymphoma seems toproliferate in response to an antigenic stimulus provided by T cell line of cells specificately activated by H...

The pituitary hormones prolactin and growth hormone are structurally related. Both hormones exist in the circulation in several molecular forms, differing in aminoacid sequences, posttranslational modifications and fragments produced by proteolytic cleavage. Heterogencity may produce a diversity of inmunological and biological actions. It has been suggested that each of this forms may be a isohormone with a different physiological role. The predominance of one of them in serun could account for the complex and often contradictory actions of the hormones...

A gene coding for the Bm86 tick protein was recently cloned, expressed in Pichia pastoris and shown to induce an inmunological response in cattle against ticks. Moreover, the Gavac vaccine (Heber Biotec S.A., Havana, Cuba), which contains this recombinant protein, has proved to control the Boophilus microplus populations under field conditions. This paper reviews the development and large-scale production of this vaccine, the efficacy of the resulting product and the strategy followed in designing its production plant...

This is a report of three cases of mycetome studied in our laboratory during the last four years. We also informed about the evolution of the first case produced by Pyrenochaeta romeroi nova species reported by Borelli in 1959. All the patients were farmer men, 18, 42 and 54 years old, from the semiarid and subhumid zones of Falcon State, located on the northwest region of Venezuela. Clinically, all patients presented the mycetome syndrome (subcutaneous edema, sinus tract and "granules"), with a evolution of six months to three years...

Two isoforms of NADP-malic enzyme have been characterized in maize leaves. The 72 kDa-form of the protein, present mainly in etiolated maize leaves, has lower specific activity than the 62 kDa-form, which is implicated in C4 metabolism and predominates in green leaves. The larger form of the enzyme has higher Km values for NADP and malate and lower PH optimum. The antibodies raised against the 62 kDa-form of the protein react with the 72 kDa-form. Steady state levels of NADP-malic enzyme, as measured by the amount of protein and activity, increase several-fold when dark-grown maize seedlings are illuminated...

We present the first case of esophagogastric devascularization and esophagogastric transection using a stapler through laparoscopic surgery. The procedure was performed in a 71-year-old diabetic woman with alcoholic liver cirrhosis (Child-Pugh B class), portal hypertension, bleeding grade III esophageal varices, and a previous bleeding episode. The surgical technique was carried out without problems, and the patient had an excellent postoperative condition. Esophagogastric devascularization with esophageal transection using a stapler through laparoscopic surgery is a feasible technique that accomplishes the same and all objectives of the open procedure...

Since 70 years ago, the possibility that the etiology of Gravidic Toxemia is inmunologic has been studied. Several researchers agree in the disminution of the levels of IgG with no modifications on the levels of complement fractions. The determination of IgA, IgM, IgC, C3 and C4 was made on fifteen pacients with gravidic toxemia and fifteen pacients that presented no complicated pregnancy. The results are the same as the reported facts like disminution of IgG, it was observed also, a disminution on the complement fractions C3 and C4...

The presence of mucopolysaccharides (MPS) in leucocytes of peripheral blood of 19 cancer patients, 13 patients with pulmonary tuberculosis and 14 normal controls, was studied histochemically. MPS was revealed in different proportions in polynuclears and mononuclears. According to the staining technics, the MPS appear to be mainly carboxylated and contain hyaluronic acid and chondroitinsulphate groups.The quantitative analysis revealed that MPS appeared only in around 3% of leucocytes of normal controls, while in the cancer patients 56% of polynuclear and 90% of mononuclears contained it...

Myasthenia gravis is an inmunological disease infrecuent during childhood. In recent years, thymectomy has gained increasing acceptance as the most effective treatment for acheiving sustained improvement in patients affected of myasthenia gravis. We report our experience in five children treated by trassternal radical thymectomy in the last five years. This patients were clinically staged following Osserman's classification as stage IIB (three cases) and stage III (two cases). All of them are in complete remission after a mean postoperative period of thirty three months...
