Summary

The targets of lipid lowering therapy in Japan are severer than those in western countries. Two hundred twenty mg/dl for total cholesterol (TCH), 140mg/dl for LDL-C, 150 mg/dl for triglyceride (TG) are used for the target values. In western countries, those values are 270 mg/dl, 190 mg/dl and 1,000 mg/dl respectively for low risk persons. But, a morbidity rate of coronary heart disease in Japan is a third in western countries. Strange to say, the number of women who accepts the therapy is twice of that of men in Japan. We have verified the targets used in Japan by some kinds of studies. We established clinical reference intervals of TCH, LDL-C, TG and HDL-C from the results of health checkup of about 700,000 persons by the method comparable to NCCLS in USA. We performed cohort studies and found cutoff points where mortalities increased significantly. These results are equal to the targets used in western countries. People diagnosed as hyperlipidemia by Japanese standard have less morbidity of strokes. If they develop strokes, their clinical indexes are better than persons in normal lipid level. In conclusion, the guideline for hyperlipidemia in Japan should be revised according to Japanese evidences soon.

Rhoudaf; Existence results for Strongly nonlinear degenerated parabolic equations via strong convergence of truncations with L 1 data..

Abstract: The existence and uniqueness of local and global solutions for the Kirchhoff–Carrier nonlinear model for the vibrations of elastic strings in noncylindrical domains

The Green’s function of the boundary-value problem (1.3) and the relevant prop- erties are to be presented later, and because of the nonlinear terms involving the higher-derivative

We consider some nonlinear second order scalar ODEs of the form x 00 + f (t, x) = 0, where f is periodic in the t–variable and show the existence of infinitely many periodic

In [13], some topological properties of solutions set for (FOSPD) problem in the convex case are established, and in [15], the compactness of the solutions set is obtained in

Our approach bases on the method of Laplace transform which has been used to study oscillation of delay differential equations [1, 16], oscillations of neu- tral differential

Thus, Fujita’s result says that there are no global, nontrivial solutions of (1.3) whenever the blow up rate for y(t) is not smaller than the decay rate for w(x, t) while there are

A solution of the quantum Liouville equation is obtained considering the Wigner transform fx, v, t of an arbitrary Schr ¨odinger function ψx, t pure state.. Expanding ψx, t by
