  • Adams-Oliver syndrome is a well-recognized autosomal dominant disorder for which mutations in six genes are etiologic, but account for only one-third of the cases. We report a patient with two genetic disorders; Adams-Oliver and Xp22.33 deletion syndromes, as well as a vestigial pseudotail. The presence of a pseudotail has not previously been reported in either of these genetic conditions. Absence of a molecular etiology underlying Adams-Oliver syndrome confirms that there are additional genetic causes to be identified.

  • Until now, there are no scientific studies for Dongkyung-i(DKI) dog, which is recently called as Deng-Kyun. This study is aimed to investigate the characteristics of DKI. According to visiting studies, DKI is an active, live and muscular dog. The dog is willing to announce the approach of strangers friendly. As the results of morphological studies, DKI is medium sized and the average weight is 22.6 kg. Its coat has mainly yellowish brown color and short hair. Morphologically, the dog showed vestigial tail and muscular and sturdy pelvic limbs. As the results of radiological studies, DKI is characterized as the absence of coccygeal vertebrae or the coccygeal agenesis. We concluded that DKI may be a Korean native canine breed characterized as short or non-tail dog. Also, we suggested that this characteristic dog is valuable to develop as a Korean native breed.

  • Adult ascarid worms from the field mice, Apodemus agrarius, were observed with a light and scanning electron microscope, and molecularly analized with 18S rRNA gene. In the scanning electron microscope, 3 prominent labia were present in the anterior end of male and female worms, but the interlabia and gubernaculum were absent. Scanning electron micrographs showed cervical alae as vestigial organs that looked like a slightly uplifted superficial sewing stitch. Total 6 pairs of post-cloacal papillae were observed on the tail of the male worms. The tail of female worms was blunt and conical shape with a spine-like structure, mucron. The eggs were sub-globular, coated with the albuminous layer and 73 by 82 ㎛ in average size. The superficial pits of T. apodemi egg (mean 8.6×6.7 ㎛) are obviously bigger than those of Toxocara spp. The partial sequence of 18S rRNA showed the sequence homology of Toxocara canis (99.6%), Toxocara cati (99.4%), Toxascaris leonina (99.4%), and Toxocara vitulorum (99.2%). Conclusively, it was confirmed that ascarid nematodes, Toxocara apodemi, recovered from striped field mice in Korea are taxonomically conspecific relationship with genus Toxocara and genetic divergence from other Toxocara species.

  • This report described a severe bilateral microphthalmia in a young Holstein calf. The anomalous calf with wry tail showed normal vigor, appetite and normal body weight except for eye defect. The orbits were shallower and smaller than normal. The orbit bilaterally contained a white small mass suspected as eyeball. A spot-like remnant of eyeball (REB) was buried in the mixture of vestigial extraocular muscles and adipose tissue of the bilateral orbit. Histologically, the REB was composed of irregularly arranged elements of ocular wall such as sclera, retina and ciliary body. But any destructive changes in the central nervous systems were not detected. This case of eye defect was defined as severe bilateral microphthalmia. The cause of this ocular defect is unknown.
