The pharmaceutical composition according to claim 1, wherein the insulin sensitivity enhancer is pioglitazone or its hydrochloride. 3. The pharmaceutical composition according to claim 1, wherein the insulin sensitivity enhancer is 5-[[4-[-2-(methyl-2-(pyridylamino)ethoxy]phenyl]-methyl]-2,4- thiazolidinedione or its pharmacologically acceptable salts. 4. The pharmaceutical composition according to claim 1, which is for prophylaxis or treatment of diabetes. 5. The pharmaceutical composition according to claim 1, which is for prophylaxis or treatment of diabetic complications. 6. The pharmaceutical composition according to claim 1, wherein the angiotension converting enzyme inhibitor is selected from the group consisting of captopril, enalapril, alacepril, delapril, ramipril, lisinopril, imidapril, benazepril, ceronapril, cilazapril, enalaprilat, fosinopril, moveltopril, perindopril, quinapril, spirapril, temocapril, and trandolapril. 7. A method for treating diabetes in a mammal in need thereof, which comprises administering to such mammal a therapeutically effective amount of an insulin sensitivity enhancer in combination with an angiotensin converting enzyme inhibitor wherein the insulin sensitivity enhancer is selected from the group consisting of 5-[4-[2-(3-ethyl-2-pyridyl)ethyl]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(4-ethyl-2-pyridyl)ethyl]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(5-ethyl-2-pyridyl)ethyl]benzyl]-2,4-thiazolidinedione; 5-[4-[2-(6-ethyl-2-pyridyl)ethyl]benzyl]-2,4-thiazolidinedione; (R)-(+)-5-[3-[4-[2-(2-furyl)-5-methyl-4-oxazolylmethoxy]-3-methoxyphenyl]pr opyl]-2,4-oxazolidinedione; 5-[[3,4-dihydro-2-(phenylmethyl)-2H-1-benzopyran-6-yl ]methyl]-2,4-thiazolidinedione; 5-[[4-[3-(5-methyl-2-phenyl-4-oxazolyl)-1-oxopropyl]phenyl]methyl]-2,4-thia zolidinedione; 5-[2-(5-methyl-2phenyl-4-oxazolylmethyl)benzofuran-5-ylmethyl]-2,4-oxazolid inedione; 5-(2-naphthalenysulfonyl)-2,4-thiazolidinedione; 4-[(2-naphthalenyl)methyl]-3H-1,2,3,5-oxathiadiazol-2oxide; 5[[4-[2-(methyl-2-pyridylamino)ethoxy]phenyl]-methyl]-2,4-thiazolidinedione ; and their pharmacologically acceptable salts. 8. The method according to claim 7, wherein the insulin sensitivity enhancer is pioglitazone or its hydrochloride. 9. The method according to claim 7, wherein the insulin sensitivity enhancer is 5-[[4-[-2-(methyl-2-pyridylamino)ethoxy]phenyl]-methyl]-2,4-thiazolidinedi one or its pharmacologically acceptable salts. 10. The method according to claim 7, wherein the insulin sensitivity enhancer and angiotensin converting enzyme inhibitor are mixed together to form an admixture and the admixture is administered to the mammal. 11. The method according to claim 7, wherein the insulin sensitivity enhancer and angiotensin converting enzyme inhibitor are not mixed together but are administered independently to the mammal. 12. The method according to claim 7, wherein the angiotensin converting enzyme inhibitor is selected from the group consisting of captopril, enalapril, alacepril, delapril, ramipril, lisinopril, imidapril, benazepril, ceronapril, cilazapril, enalaprilat, fosinopril, moveltopril, perindopril, quinapril, spirapril, temocapril, and trandolapril. 13. A method for treating diabetic complications in a mammal in need thereof, which comprises administering to such mammal a therapeutically effective amount of an insulin sensitivity enhancer in combination with an angiotensin converting enzyme inhibitor. 14. The method according to claim 13, wherein the insulin sensitivity enhancer is pioglitazone or its hydrochloride. 15.
