[Effect of roasted wheat flour on the intestinal absorption and zinc metabolism of rats]. / Influencia del gofio de trigo sobre la absorción intestinal y el metabolismo del cinc en ratas.

24 experiences have been carried in 8 younger Wistar female rats that been submitted to three different diets considering fibers and phytates, with the purpose to demonstrate if "gofio de trigo" of popular consumption in Canary Islands, and rich in these substances affects intestinal absorption of zinc in the diet. Authors have observed a very significant elevation of zinc in feces, during the control period. An important decrease of zinc in hair has been observed indicating a deficit of corporal ion although zinc in serum remained in its normal limit. Authors emphasize the fact that under these circumstances, removal of urinary zinc is not a useful guide for diagnosis of deficiency state.

[Comparison of the levels of serum ferritin and other hematologic parameters in males and pre-menarche and post-menarche females]. / Comparación de los niveles de ferritina sérica y otros parámetros hematológicos en varones y hembras premenárquicas y postmenárquicas.

Our study group consisted of 43 healthy preadolescence and adolescence of which 17 were boys and 13 premenarcheal and 13 postmenarcheal girls. Haematocrit, haemoglobin, serum iron, transferrin saturation, total iron-binding capacity, latent iron-binding capacity and serum ferritin were analyzed. Authors found that post-menarcheal girls are at lower levels than boys and that menstrual blood loss is a significant factor in determining iron status.

[Serum zinc during labor and in the newborn infant at term]. / Estudio del cinc sérico en el parto y recién nacido a término.

A study of serum zinc by atomic absorption spectrophotometry was carried out in peripheral blood samples form a group of 30 full-term mothers and umbilical cord samples from their newborns. Peripheral blood samples from 15 non-pregnant healthy women and umbilical cord samples collected within the first 24 hours in 20 healthy newborns were also obtained. Serum zinc in non-pregnant women yielded higher values which were significant (p less than 0,01), any way, the level of significance was higher when authors compared full term pregnant women with full term newborns in the first day of life.

[A dynamic study of HGH, zinc and copper in diabetic girls. Preliminary report]. / Estudio dinámico de HGH, cinc y cobre en niñas diabéticas. Comunicación previa.

A dynamic study study on secretion of HGH in diabetic girls under the combined stimulus of L-dopa and L-arginina is performed. Serum levels for Zinc and copper are measured. Results show that as HGH increase, copper levels decrease. Correlation (r = 0.81, p = 0.05) points to an inverse dependence of both parameters. Concomitantly, the values obtained for zinc and copper are correlated (r = 0.82, p = 0.03). During stimulation, all patients showed an increase in glycemia and a significant correlation between both parameters was found (r = 0.76, p = 0.05).

[Anorexia nervosa. Presentation of two cases]. / Anorexia nerviosa.

Two patients with anorexia nervosa were studied. One of them showed cerebral atrophy by computed tomography (CT) of the brain. This finding has been reported previously in three cases. No other reports have been found in Spanish literature. This data could be merely a CT finding. Etiopathogenic and therapeutic evolution is discussed. Behavior modification, based in experimental psychology was used in treatment. Hypercaloric and hyperproteic feeding was also used.

[Holt-Oram syndrome with chromosomopathy (author's transl)]. / Síndrome de Holt-Oram con cromosomopatía.

A patient whose cardiac and skeletal malformations are compatible with Holt-Oram syndrome is presented. The interest lays in the fact that cytogenetic shows and excess of chromosomic material in the long arm of the sixth chromosome. Authors consider this to be a "de novo" finding as the study practiced on the parents has been normal. This chromosomic anomaly has not been, to their knowledge, reported in the literature. All known cases have a normal karyotype.

[Study of serum copper and ceruloplasmin in the newborn (author's transl)]. / Estudio del cobre y ceruloplasmina en el parto y recién nacido a término.

Serum samples for copper and ceruloplasmin were measured by atomic absorption spectrophotometry. Peripheral blood samples from 30 children-bearing mothers and umbilical cord samples from their clinically normal full-term products were obtained. Mean serum copper for mothers was 216.23 +/- 49.44 mcg./dl. and that for newborns was 48.87 +/- 7.95 mcg./dl. (p less than 0.001). Maternal ceruloplasmin was 66.53 +/- 8.22 mcg./dl. while values for newborns were 11.6 +/- +/- 3.41 mcg./dl. (p less than 0.001). A significant difference (p less than 0.005) in ceruloplasmin values for newborns with a 38-40 week gestation and those with a 41-42 week gestation, were found. The results are compared with those reported in the literature.

[Ataxia-telangiectasis (author's transl)]. / Ataxia-telangiectasia.

A case of ataxia-telangiectasis is reported, the pattern of cellulo-humoral immunity is altered with frequent infection of the respiratory tract. Emphasis is made on the new approach to brain alterations by means of cerebral angiogammagraphy and sequential gammagraphy.

[Chromosome 18 long-arm deletion. Report of 1 case]. / Delección de los brazos largos del cromosoma 18.

Authors report a ten month old girl with multiple malformations: midfacial hypoplasia, hypertelorism, carp mouth, very marked antihelix, poor muscular tone, spindle-shaped fingers with a high frequency of whirles and low levels of serum immunoglobulin A. In leukocyte culture, patient shows a deletion of the long arm of a 18 chromosome.
