Inheritance of dermatoglyphic configurations in the rat.

Inheritance of dermatoglyphic configurations was studied on the palmar III interdigital pad of the rat (Rattus norvegicus). Four rats from each of the WKS and ACI/N inbred strains were mated with each other, and 54 F1 and 88 F2 hybrids were obtained. In addition, 52 offspring were produced by backcross mating between F1 hybrids and WKS and ACI/N parents. Whorls were the predominant pattern in the WKS strain and triradial patterns characterized the ACI/N strains. The F1 hybrids showed a wide range of pattern types, consisting of whorls, loops, cusps, arches, and triradial patterns. These patterns were intermediate in size between the two inbred strains. The F2 hybrids presented a distribution of patterns with a similar range as the F1, but the frequencies of some types were different. Patterns in the offspring of each backcross demonstrated a slight shift towards the characteristic pattern of the parental inbred strain. No sex difference was observed. Generally, the bilateral differences were striking, with a radial direction predominating on the left palm, and an ulnar one on the right palm, respectively. This study suggests that the dermal patterns are genetically determined, but also are influenced by environmental factors, especially in the hybrids.

Clinical usefulness of oral itraconazole, an antimycotic drug, for refractory atopic dermatitis.

We investigated the clinical usefulness of oral itraconazole for refractory atopic dermatitis in a crossover study. Patients with refractory atopic dermatitis were divided into two groups: Group A; a combination of itraconazole plus a conventional lactobacillus preparation was administered for 8 weeks, followed by lactobacillus preparation alone for 8 weeks, Group B; lactobacillus preparation alone was administered for 8 weeks, followed by itraconazole plus lactobacillus for 8 weeks. In both groups, a decrease in dose or strength of concomitant topical steroids was observed at the end of the treatment course of itraconazole, and improvement of parameters such as eosinophil count, serum IgE level and specific IgE antibody titers to fungi was also observed after the administration of itraconazole. These results suggest that oral itraconazole is useful for the treatment of intractable atopic dermatitis patients who do not respond to conventional therapeutic approaches.
