Introduction |
|
The department has been founded to develop education
and research for pathology and clinical therapeutics
of various types of human diseases. Anatomy and
basic physiology of humans were also included
in the professional training of education.
Dr. Kenji Mizuno, professor and chairman of the
department, graduated from Fukushima Medical University
School of Medicine in 1976. He received his doctor's
degree of medicine from the university in 1983
with a clinical research concerning biochemical
characteristics and pathophysiological significance
of angiotensin-converting enzyme (ACE) in urine
of patients with essential hypertension. His main
them of research has been thoroughly the etiology
and therapeutic aspect of hypertension. Role of
extrarenal renin-angiotensin system in pathogenesis
of essential hypertension is one of the important
issues of research. In this connection, he worked
with Professor T. Inagami, at the Department of
Biochemistry, Vanderbilt University School of
Medicine in Tennessee, from 1986 to 1988, while
which he proved the presence of renin-secretory
granules in rat adrenal cortex (Journal of Clinical
Investigation, 82, 1007-1016, 1988). Recently,
his work has focused on the role of gene polymorphism
of various vasoactive hormones and thrombogenetic
substances in target organ damages of either hypertension
or diabetes mellitus. He revealed some relationships
between gene polymorphisms of plasminogen activator
inhibitor type-1 (PAI-1), platelet activating factor acetylhydrolase (PAF-AH) and ACE and cerebrovascular
damage in hypertension. More recently, a study
is under progress of correlation of gene polymorphism
of angiotensin II type I receptor (ATIIr1)
and efficacy of its specific antagonist candesartan
in patients with diabetic nephropathy. |

Research |
|
As stated above,
our main research includes |
1) |
relationships between gene polymorphisms
of PAI-1, PAF-AH, and ACE and target organ
damages in hypertensive patients |
2) |
significance of gene polymorphism of ATIIR1in
the initiation and/or development of diabetic
nephropathy in patients with type 2 diabetes
mellitus (non-insulin dependent diabetes
mellitus, NIDDM), and |
3) |
the efficacy of ATIIR1antagonist
candesartan for protecting diverse diabetic
complications in NIDDM patients. In addition,
role of endothelial cells for atherosclerotic
vascular changes in hypertension and diabetes
mellitus has recently been started. To this
end, effects of various kinds of vasoactive
substances such as angiotensin 2, endothelin,
insulin and homocystein on tissue plasminogen
activator (t-PA) as well as on PAI-1 are
currently under investigation by using cultured
endothelial cells from human umbilical vein
(HUVEC) at a gene level. These works are
mainly collaborated by the assistant Kayoko
Hashimoto, a graduate from Chiba University
School of Nursing. |
|
The main findings from the first research
have already been accepted and presented
as oral and poster presentations in the
18th Scientific Meeting of the International
Society of Hypertension, held at Chicago,
USA in August 2000. These results were abstracted
in the Journal of Hypertension, 18 (supp
4), 2000. |

|
Education |
|
|
According to the curriculum, lectures
for basic human anatomy regularly start
from April and finish at September for first-year
students. Then, a series of lectures on
basic human physiology is held for 6 months
from October. For second-year students,
fundamental pathology of human diseases
and therapeutics are lectured throughout
the year. Tests are usually provided for
promotion at September and March. |
