We report 27 cases of gas gangrene treated at the University Hospital of Liege since the Anesthesiology Department has been using a caisson for hyperbaric oxygen therapy. Frequency of gas gangrene does not appear to have decreased during recent years. The etiologies now encountered are mainly of post-traumatic and post-operative origin (especially surgery on the digestive tract); arterial insufficiency is a predisposing factor. The prognosis depends on the speed with which an effectual treatment is started; the latter consists in intensive hyperbaric oxygen therapy, antibiotic therapy and resuscitation. Surgery should be as conservative as possible and is undertaken only when progress of the disease has been checked by hyperbaric oxygen therapy. The association of these various modes of treatment proves effectual despite a still significant mortality. [less ▲]

Regulation of growth hormone gene expression: synergistic effects of thyroid and glucocorticoid hormones

Cultured rat pituitary cells (GC) respond to thyroid and glucocorticoid hormones by increases in growth hormone production and growth hormone mRNA. When these cells are transferred from medium containing normal animal serum (with 1.8 mug of thyroxine per dl) to a medium containing serum from a thyroidectomized calf, "hypothyroid medium" (with no detectable thyroid hormone), growth hormone production decreases markedly. In cells maintained for 5 days in hypothyroid medium, triiodothyronine induces within 50 hr a 17-fold increase in growth hormone production whereas glucocorticoids, during the same time, produce a negligible (3-fold or less) stimulation. In combination, the two hormones promote a 45-fold stimulation. In all instances the changes in growth hormone production are paralleled by changes in the levels of growth hormone mRNA as measured by cell-free translation. The transfer to hypothyroid medium and the hormonal induction do not affect the relative activities of other mRNAs whose products are detectable on polyacrylamide gels. These studies indicate that thyroid hormone can be an activator of the expression of the growth hormone gene. The results also show that triiodothyronine controls the magnitude of the effect of glucocorticoids on growth hormone mRNA, and provide a model for "permissive" triiodothyronine action. The synergistic effect of these two classes of hormone suggests that they increase levels of growth hormone mRNA by different mechanisms. [less ▲]

Nucleotide sequence of part of the gene for human chorionic somatomammotropin: purification of DNA complementary to predominant mRNA species

A novel purification procedure for DNA complementary to individual mRNA species has been developed by using restriction endonuclease cleavage of cDNA transcribed from a complex mixture of mRNAs. This procedure has allowed us to isolate and analyze DNA fragments complementary to the mRNA coding for the human peptide hormone chorionic somatomammotropin (HCS). The mRNA for this hormone is a major constituent of placental polyadenylated RNA as shown by in vitro translation of placental RNA and by nucleic acid hybridization using HCS cDNA as a specific probe. The purification of HCS cDNA was achieved by Hae III and Hha I restriction endonuclease cleavage of single-stranded cDNA synthesized in vitro from total polyadenylated placental RNA. Polyacrylamide gel electrophoresis of the products allowed detection and purification of discrete DNA fragments. A comparison of the nucleotide sequence of these fragments with that predicted from the amino acid sequence of HCS demonstrated that the fragments are transcripts of HCS mRNA, containing most of the translated and 3′ untranslated regions. The latter region is characterized by a UAG termination codon immediately adjacent to the translated region (a second in phase UAG occurs 9 nucleotides away) and a palindromic sequence (GUGACCCCUCCCCAGUG) centered 27 nucleotides from the termination codon. The purification scheme outlined for HCS cCNA should be applicable to DNA sequences complementary to mRNA species which represent at least 2% of any polyadenylated RNA preparation. This was demonstrated by restriction endonuclease cleavage of cDNA synthesized from a mixture of purified rabbit globin and total polyadenylated human placental RNAs. [less ▲]
