Transitions of designation categories of the Wildlife Protection Areas and the extent of these designated areas were analyzed using government guidelines and wildlife statistics. A remarkable decrease was observed in the designated area for the “forest habitat type”, which occupies the largest proportion. For all other categories except the “habitat corridor type”, there was an increase in the designated area. As the number of hunters decreases and the damage caused by wildlife becomes serious, the significance of hunting-prohibited areas is declining. Therefore, “forest habitat type”, “large-scale habitat type” and “habitat corridor type” should be designated with a clear intention to secure the original habitat for wildlife, which is supported by science-based management. The categories such as “endangered species habitat type” and “large migration areas type”, whose designation as Special Protection Areas is imperative, are expected to function as true nature conservation areas by effective planning and design of the Special Protection Areas and surrounding buffer zones.

Within Japan, the Japanese Quail Coturnix japonica is bird species familiar to many people. It was first designated as a game species in 1918, and has been captive-bred and released into the wild since the early 1970s. An examination of the annual numbers of quails hunted, based on Wildlife Statistics data and other literature sources, indicates that the population level of Japanese Quail started to decline in the 1930s, and has subsequently shown a dramatic decrease. Japanese Quail is thought to have no harmful effects on agriculture, and has retained its status as a game species solely owing to its value as a hunting target. In 1998 the Japanese Quail was listed as DD (Data Deficient) on the Japanese Red List, and its designation as a game species should therefore be reconsidered as soon as possible. For the Japanese Quail population to recover from its from endangered status a combination of stricter hunting regulations and the active restoration of suitable habitat is urgently required.

症例は40歳台,男性.201X年2月,1週間来の腹痛と嘔吐の増悪を主訴に当院を受診.来院時,腹部全体の圧痛・反跳痛を認めた.腹部X線画像で上行結腸周囲に多数の点状石灰化像を認めた.小腸niveau像を認めたが,free airは認めなかった.腹部造影CT検査では,右結腸静脈の石灰化に加え,上行結腸の腸管壁の造影不良と壁肥厚を認めたため,腸管壊死と診断して,緊急開腹手術を行った.開腹時所見では,上行結腸から横行結腸の中央部に腸管壊死を認め,結腸部分切除を行った.病理検査では,粘膜面の潰瘍形成,静脈血管壁の石灰化と上行結腸粘膜下層の広範な線維化領域を認め,特発性腸間膜静脈硬化症による虚血性大腸炎と診断した.術後経過は良好で,術後16病日に退院となった.本症例は10年以上の漢方薬(梔子柏皮湯®)の服用歴があり,病因との関連性が示唆された.現在,漢方薬内服を中止して経過観察中である.
