 最初は、わからないことが多いと思います。教科書で学んだ事と現場では多くのことが異なります。しかし、刺激があって学ぶ意欲が増します。循環器学や腫瘍学は、複雑で必要とする基礎知識量が多いため、嫌われることが多いです。しかし、実際の臨床現場を多く体験することで、診察で得た知識が繋り、大きなものとなります。また、採血や超音波検査手技などを学び、実際に技術的なことを習得することによって、さらに学習意欲がわきます。そして、卒業後も⽣涯学び続けることが重要で、かつ楽しいといった考え方を学生が持ってくれるかどうかが、大学教育が成功した証だと考えています。少しでも小動物臨床の魅力をお伝えできることができればと思っているので、興味があれば見学にいらしてください。

Self introduction

I am from Kagoshima. Sometimes, I go back to kagoshima to enjoy fishing. When I was a child, I was an active boy who ran around the fields and played swimming. But since I have grown up an adult, I spend my days being chased by work. My research fields are about evaluation methods for cardiovascular disease and cancer. Just like people, in dogs and cats, the opportunities which cardiovascular disease and cancer are diagnosed increase. I'd like to do my best to make the animals live as long as possible with a satisfaction.

Introduction

With the aging of pet animals, the opportunities which cardiovascular disease and cancer are diagnosed increases in dogs and cat. However, since animals are unable to communicate verbally, correct diagnosis and severity evaluation are difficult. For this reason, my goal is to accurately evaluate severity of cardiovascular diseases and cancer using echocardiography and blood biomarkers, leading to correct treatment.
Recently, I am focusing our research on pulmonary hypertension. Pulmonary hypertension is a pathological condition characterized by an increased pulmonary arterial pressure, and which can lead to dyspnea, syncope. It is difficult to evaluate the severity of pulmonary hypertension and to judge the effectiveness of treatment, and there is currently no unified evaluation method for this disease. Therefore, our laboratory performs studies on hemodynamic analysis of pulmonary artery to evaluate the severity of pulmonary hypertension. In addition, our laboratory has various topics about pathophysiology and treatment of cardiovascular diseases. Furthermore, we investigate the cardiac function of large animals using echocardiography to elucidate the pathogenesis of cardiovascular diseases.
In the field of oncology, our research focuses on haemangiosarcoma. Haemangiosarcoma which is derived from vascular endothelial cells behaves very poorly. Early detection of hemangiosarcoma is essential for a good prognosis. Now, our laboratory is collaborating with companies and other laboratories on the theme of early detection of haemangiosarcoma using blood biomarkers.

Hemodynamic analysis of pulmonary artery by echocardiography
Hemodynamic analysis by catheterization
Measurement of blood biomarkers by ELISA
