Malignant mesenchymoma of the heart.
An autopsy case of malignant cardiac mesenchymoma, which arose in the atrial septum was presented. This tumor contained fibrosarcomatous, rhabdomyosarcomatous, chondrosarcomatous and osseous elements. A small metastatic lesion was found in the lung. Histogenesis of this tumor was also considered with a survey of literature.

Retinal dysplasia--A report of two surgical cases.
Two surgical cases of retinal dysplasia are reported. The one is unlateral (left-sided) with microphthalmus and the other bilateral. Chromosome test in the latter case showed no abnormality. In both cases the left eye was enucleated under the clinical diagnosis of retinoblastoma. There was a mass of loose connective tissue behind the lens which was covered by a completely detached retina. Histological examination revealed the presence of branching tubes of primitive retinal structure and large rosettes. The use of the term retinal dysplasia in distinction from Reese's syndrome is mentioned and some morphological characteristics of primitive retinal structure are described.

Genetic relationships among Japanese native breeds of chicken based on microsatellite DNA polymorphisms.
Genetic relationships among Japanese native breeds of chickens were studied on the basis of microsatellite DNA polymorphisms. DNA samples from 10 Japanese native breeds (Iwate-Jidori, Aizu-Jidori, Sadohige-Jidori, Siba-Tori, Onaga-Dori, Echigonankin, Hinai, Kinpa, Koeyoshi, and Tomaru) and one imported breed (White Leghorn) were analyzed using eight microsatellite markers that were isolated from a microsatellite DNA-enriched library of chickens (Takahashi et al. 1996). The PCR primers to detect (CA)n repeat length polymorphisms were synthesized based on the sequences of clones, and these markers were typed by PCR amplification and electrophoresis using a DNA sequencer. Since all eight microsatellite markers were polymorphic, genetic distance between the breeds could be calculated based on the frequencies of alleles of the microsatellites and phylogenetic relationships between the breeds could be estimated. Most Japanese native chickens were grouped into three groups that correspond to the origin breeds, Jidori, Shokoku, and Shamo. The results suggest that microsatellite DNA markers are a useful tool for studying the genetic relationships among chicken breeds.
