Inhibitory effects of essential oil components on growth of food-contaminating fungi.

The antifungal activity of several components of essential oils were evaluated using a paper-disk method. The substances investigated are structurally related to eugenol. Equimolar amounts were tested on more than ten fungal strains known to contaminate food. Iso-eugenol, cinnamaldehyde, carvacrol, eugenol and thymol revealed the strongest antifungal activity. The most resistant strain appeared to be Penicillium verrucosum var. cyclopium, and the most sensitive was P. viridicatum. Some of the structural effects were considered, including a free hydroxyl group in connection with an alkyl substituent which seemed to represent an especially active configuration of phenolic compounds and which rendered antimicrobial activity.

[Familial pelvi-scapulary dysplasia with anomalies of the epiphyses, dwarfism and dysmorphy: a new syndrome? (author's transl)].

A North African brother and his sister, whose parents were first cousins, presented with the same disorder. It consisted of congenital dwarfism, facial dysmorphy and several skeletal anomalies including bilateral agenesis of the ala of scapula and hypoplasia of the ala of ilium and acetabulum, responsible for hip dislocation. No similar case was found in the literature. A recessive autosomal transmission of the disease is suggested.

Canine exocrine pancreatic secretory changes induced by calcium or ethanol plus calcium intraduodenal infusion.

In dogs provided with chronic gastric and pancreatic fistulas (Thomas cannula), an 80-minute intraduodenal CaCl2 (0.6 mM/kg.) infusion against a background of secretin perfusion (GIH, 1.0 CU/kg./hr.) elicits a complex "pancreon" response consisting of both excitatory and inhibitory effects on the protein and alkaline components, respectively, of pancreatic secretion. It is postulated that these pancreatic secretion changes are the result of the interplay of released CCK and calcitonin. The lack of pancreatic secretion modifications when ethanol (0.7 mg./kg.) was added to the intraduodenal CaCl2 infusion suggests that the former counteracts the effects of the latter on the nerves and/or the endocrine cells of the gut. Ca++ concentration and output in pancreatic secretion did not change significantly either with the intraduodenal CaCl2 alone or associated with ethanol. Fasting blood Ca++ levels were not modified either by the secretin perfusion or by the intraduodenal CaCl2 infusion, either given alone or associated with ethanol.

Physical studies of the interaction between the Escherichia coli DNA binding protein and nucleic acids.

The interaction of nucleic acid with the Escherichia coli DNA-binding protein has been studied by fluorescence emission spectroscopy and sedimentation velocity analysis. The protein binds to single-strand DNA with an apparent equilibrium dissociation constant of 2 X 10(-9). It binds to the homopolymers poly (dA) and poly (dT) slightly more tightly, but has a larger apparent equilibrium dissociation constant to poly (dC). The protein also binds tightly to ribohomopolymers and to tRNA, but not to duplex DNA. By the use of defined-length oligonucleotides, it has been shown that the protein binds to DNA in a highly cooperative manner. The extent of cooperativity is seen as the difference in binding between an isolated monomeric protein molecule bound to DNA and two or more molecules binding to contiguous sites.
