| The embryonic development of the facial area, neck, nasal, oral and pharyngeal cavities with glands, involves growth and fusion of multi-dimensional processes. There is involvement of elements from the embryo-derived local 3 layers cells further neural crest derived cells from the neighbors rhombomeres. The neural crest cells are involved in the formation of local skeleton, among other structures. The study of evolution from jawless vertebrates shows us how Hox genes are expressed in different species, and how this determines the formation of different structures. The following review contemplate some morphological, molecular and evolutionary basis of facial and neck development, with emphasis on mammals with an epilogue concerning to the face and neck... |

| 三次元超音波検査法の小動物臨床への応用の可能性を探求するために，妊娠後期の6 歳 のビーグル犬に対して，腹部用三次元プローブを用いた三次元超音波検査法を出産まで数 日毎に行い，8 頭の胎子の顔を描出しようと試みた。胎子の顔の三次元超音波画像が全ての 検査日において少なくとも1 頭の胎子で得られたが，胎子が成長するにつれて良好な画像 を得るのは難しくなった。交配後43 日目ならびに45 日目では胎子の顔の鮮明な三次元画 像が容易に得られた。技術的に解決しなければならない問題がいくつか残されているもの の，適切に用いさえすれば，三次元超音波検査法は従来の二次元超音波検査法を補足する 方法として小動物臨床に応用可能であると考えられる。 This study was delineated to explore the possibility of using three-dimensional ultrasonography in small animal practice. In a 6-year-old pregnant beagle bitch with eight feti, we tried to visualize the feti faces with three-dimensional ultrasonography by scanning with a transabdominal three-dimensional probe every two to three days until parturition. At each date of examination, Three-dimensional sonographic images of the feti faces were... |
