Ascitic feline coronavirus (FCoV) RNA was examined in 854 feline infectious peritonitis (FIP)-suspected cats by RT-PCR. The positivity was significantly higher in purebreds (62.2%) than in crossbreds (34.8%) (P<0.0001). Among purebreds, the positivity in Norwegian Forest Cat (92.3%) and Scottish Fold (77.6%) were significantly higher than the average of purebreds (P=0.0274 and 0.0251, respectively). The positivity was significantly higher in males (51.5%) than in females (35.7%) (P<0.0001), whereas no gender difference has generally been noted in FCoV antibody-prevalence, indicating that FIP more frequently develops in males among FCoV-infected cats. Genotyping was performed for 377 gene-positive specimens. Type I (8.3%) was far more predominantly detected than type II (10.6%) (P<0.0001), similar to previous serological and genetic surveys.

スイカは、世界で最も人気のある果物の一つです。日本では、スイカの自然な甘さを引き立てるために、塩を振って食べる人がいます。しかし、この食行動に関連する要因については、ほとんど知られていません。ここでは、スイカに塩のヘドニック反応、味の好み、および自閉傾向との関係を調べました。参加者は90名で,オンラインアンケートを実施した。その結果、スイカに塩のヘドニック反応は、苦味の好みと負の相関があり、苦味が苦手な参加者ほど、スイカに塩を美味しく食べる傾向があった。これらの結果は、塩が苦味を抑制する効果があることを示している。さらに、スイカに塩のヘドニック評価や基本味の好み評価には、自閉傾向の影響は見られなかった。このように、自閉傾向は、食行動や味の嗜好にほとんど影響しない可能性があると示している。

A 5-year project of "Antarctic Climate Research (ACR)" has been started from JARE-28 in 1987. Observations of clouds and precipitation were carried out using vertical pointing radar and two microwave radiometers in 1988 (JARE-29), the second year of this project. The observations of vertical pointing radar were begun on February 24,1988,and the microwave radiometers observations were handed over to JARE-29 by JARE-28 on February 1,1988. The characteristics of the precipitation in 1988 at Syowa Station, on the coast of Antarctica, are described in this paper. Ten days variation of precipitation are calculated using radar echo intensity at 300m altitude and the relation between radar reflectivity factor (Z) and rainfall rate (R), the so-called Z-R relation. The values obtained from this method are free from the contamination of drifting snow which affects precipitation obtained by rain gauge. The result shows the maximum precipitation in autumn (February and March) and the minimum precipitation in spring (September and October). Low precipitation in spring seems to be characteristic of 1988 at Syowa Station. Snow crystals of precipitation there can be classified into three types : graupel or a heavily rimed crystals, grathering bullets, and other types of crystals such as snowflakes, dendrites and plates. The first and second types of crystals were mainly observed throughout 1988. The height of the radar echo was relatively low; namely, the echo top was under 2km in altitude, in the period when the first type of crystals mainly fell. On the other hand, in the period when the second type of crystals mainly fell, the echo top was often over 4km altitude.
