[Treatment of coronary insufficiency with a combination of 2 nitro-derivatives. Controlled pluricentric clinical trial].

The effectiveness of an association of two nitroderivatives (Stenodylate) was compared with that of its individual components. The association was found more effective in the relief of both subjective and objective symptoms in 118 cases of coronary insufficiency. In addition, it was well tolerated and would appear to be indicated in the management of this form.

Factors enhancing Agrobacterium tumefaciens-mediated gene transfer in peanut (Arachis hypogaea L.).

Parameters enhancing Agrobacterium-mediated transfer of foreign genes to peanut (Arachis hypogaea L.) cells were investigated. An intron-containing beta-glucuronidase uidA (gusA) gene under the transcriptional control of CaMV 35S promoter served as a reporter. Transformation frequency was evaluated by scoring the number of sectors expressing GUS activity on leaf and epicotyl explants. The 'Valencia Select' market type cv. New Mexico was more amenable to Agrobacterium transformation than the 'runner' market type cultivars tested (Florunner, Georgia Runner, Sunrunner, or South Runner). The disarmed Agrobacterium tumefaciens strain EHA101 was superior in facilitating the transfer of uidA gene to peanut cells compared to the disarmed strain C58. Rinsing of explants in half-strength Murashige-Skoog (MS) media prior to infection by Agrobacterium significantly increased the transformation efficiency. The use of cocultivation media containing high auxin [1.0 or 2.5 mg/l (4.53 micromolar or 11.31 micromolar) 2,4-D] and low cytokinin [0.25 or 0.5 mg/l (1.0 micromolar or 2.0 micromolar) BA] promoted higher transformation than either hormone-free or thidiazuron-containing medium. The polarity of the epicotyl during cocultivation was important; explants incubated in an inverted (vertically) manner followed by a vertically upright position resulted in improved transformation and shoot regeneration frequencies. Preculture of explants in MS basal medium or with 2.5 mg thidiazuron per l prior to infection drastically decreased the number of transformed zones. The optimized protocol was used to obtain transient transformation frequencies ranging from 12% to 36% for leaf explants, 15% to 42% for epicotyls. Initial evidence of transformation was obtained by polymerase chain reaction and subsequently confirmed by Southern analysis of regenerated plants.

[Prognostic factors for postoperative mortality in cancer of the esophagus. Analysis of 46 cases].

Forty six patients with esophageal cancer underwent surgery between January 1986 and January 1990. In 14 patients (30.4%) distant metastases were recognized before surgery, whereas in 29 cases (63%) regional neoplastic lymph node infiltration was observed during surgery. Complications during and after surgery occurred in 32 (69.6%) patients and in 30 cases (65.2%) respectively. During the first 30 days after surgery 12 patients died. This represents a postoperative mortality of 26.1%. Among a total number of 51 variables analyzed in this study, 11 influenced the postoperative mortality: duration of intubation, previous history of toxic syndrome, presence of distant metastases before surgery, presence of neoplastic node involvement during surgery, tumor size greater than 4 cm, localization of the tumor at the middle third of the esophagus, respiratory insufficiency, cardiac failure, septic shock, and suture failure during the postoperative phase. However, multivariate analysis revealed that only three of these variables had an independent prognostic value on postoperative mortality: tumor size, presence of distant metastases, and development of respiratory insufficiency during the postoperative period.

[Thalassemic syndromes and anesthesia].

Thalassemic syndromes are produced by a quantitative defect in the synthesis of globin chains of hemoglobin. They are classified according to the severity of the clinical picture and to the type of globin chain that is affected. Physiopathology, clinical picture, and treatment of thalassemias are discussed in this work. Thalassemia minor does not create, in general, anesthetic problems. In cases of thalassemia major one should consider not only problems derived from the severity of the anemia it self, but also those related to transfusional therapy, and to bony malformations that may disturb tracheal intubation. Discussion on the management of homozygotic thalassemia during the pre, per, and postoperative phase completes this revision.
