Analysis of 31 CFTR mutations in 55 families from the South of Spain.

We carried out a molecular analysis of 350 chromosomes from 55 families originating from the South of Spain (Andalucia) who were diagnosed with cystic fibrosis (CF). We used polymerase chain reaction, followed by an oligonucleotide ligation assay (OLA) and sequence-coded separation using capillary electrophoresis. A frequency of 43.5% for DeltaF508 was found, making it the most common CF mutation in our sample. Seven more mutations (G542X, R334W, R1162X, 2789+5G-->A, R117H, DeltaI507 and W1282X) were detected and accounted for 24.7% of the total. The remaining mutations (31.8%) were undetectable with the methodology used in this study.

Insulin effects on glucose utilization by human lymphocytes.

In recently isolated human lymphocytes, no effect of insulin on (U-14C) glucose incorporation into CO2, triglycerides and glycogen, was found over a wide range of insulin concentration. The rates of glucose oxidation, synthesis of triglycerides and synthesis of glycogen are much lower than those observed in chicken and rat adipocytes. The authors discard the possibility of using the human lymphocyte as an instrument in the study of the insulin action on normal and altered human physiology.

Study of a set of chromatographic parameters for the determination of estrogens.

Optimum chromatographic parameters for the separation and detection of estrogen TMS derivatives are described. Estrogens are best separated by using a 2 m glass column with 1% SE-30 load; an 8' iso temperature program, 230 degrees C, 3 degrees C/min, 296 degrees C; 24 ml/min nitrogen flow; 33 ml/min hydrogen flow and 1.5 Kg/cm2 air pressure.

[The urinary excretion of pregnanediol during pregnancy determined by gas-liquid chromatography. I. Its evolution throughout the normal and pathological pregnancy (author's transl)].

Employing the technique described by Van Kampen and Anker, modified by Macarulla et al., 180 pregnant women have been studied (66 normals and 114 with different pathology: infertility, toxemia, diabetes, Rh isoinmunization, gemelar pregnancy and abortions), taking 319 determinations of pregnanediol in 24 hours urine samples. The analysis of the results show in normal pregnancy a progressive increase of the urinary pregnanediol from the beginning of gestation, this increase being more intense from the 20th week, reaching the maximum value in the 37th week and from this point descending slowly. In patients with toxemia, the values of pregnanediol (in the majority of the cases) are decreased, while in pregnant women with antecedents of infertility are increased from the 36th week of pregnancy, although they had protective treatment from first months of pregnancy. No manifest deviations of urinary pregnanediol from the normal values exist in diabetic pregnant women, Rb isoinmunization or gemelar pregnancies. In aborted pregnancies the pregnanediol values are markedly decreased without a tendency to increase, contrary to the threats of abortion in full-term pregnancies.

[The urinary excretion of pregnanediol during pregnancy determined by gas-liquid chromatography. II. Its relation with other parameters controling pregnancy (author's transl)].

The relation between the urinary pregnanediol determined by gas-liquid chromatography during pregnancy, with ultrasonic findings (biparietal diameter, thickness and echorrefringency of the placenta and the appreciated quantity of amniotic fluid), with biochemical parameters of control of pregnancy (beta-glucoronidase, total and thermostable alkaline phosphatase), with amnioscopic findings, and with several studied parameters of the amniotic fluid by amniocentesis, were studied. A good relation exists with the parameters which denote placentary insufficiency and fetal risk (irregularity in the homogeneity of the placenta, elevation of the total and thermostable alkaline phosphatase, positive amnioscopy) and also with those that are related with fetal maturity (biparietal diameter, shake test, organge cells, creatinine in amniotic fluid, etc.). These results indicate that the determination of urinary pregnanediol can be one of the tests controlling the normal and pathological pregnancies, being useful in the detection of fetal risk and the diagnosis of the intrauterine fetal maturity.
