Male and female virgin rats and breeder rats with naturally-occurring diabetes, hypertension and arteriosclerosis, were made severely diabetic with a single, subcutaneous injection of alloxan (10 mg/100 g b.w.), after an 18 h fast. During five months of unrelenting diabetes, some animals became obese while others became emaciated. Only the emaciated animals survived but they were blind, their adrenal glands were hemorrhagic, hypertrophied and thrombosed, thymi involuted, kidneys swollen, hearts reduced in size while testes and ovaries were atrophic. Serum CPK, SGOT and SGPT were elevated concomitant with extensive cardiovascular damage, hepatic steatosis and generalized catabolism. Circulating triglycerides and free fatty acids were markedly elevated with total cholesterol only slightly increased. BUN and serum calcium levels were also greatly elevated. Sub-normal Cmpd. B levels indicated impaired adrenal steroidogenesis. Virgin rats developed arteriosclerosis and male and female breeder rats showed exacerbation of their pre-existing aortic sclerosis as well as P.A.N. lesions in their small-sized arteries. It is believed that severe diabetes causes exacerbation of the endogenous hormonal milieu resulting from abnormal hypothalamic-pituitary-adrenal function induced by repeated breeding, which conditions the connective tissue components of the arterial wall of rats toward accelerated degenerative changes.

Arteriosclerosis is caused by many factors. These pathogenic factors especially over-nutrition, nicotinabusus, deficiency of muscular exercise, muscular overstrain, emotional stress and concomitant basic diseases, especially arterial hypertension, diabetes mellitus and dyslipidemia are the most important points for preventive and therapeutical action. When possible the risk factors has to be eliminated, arterial hypertension, diabetes mellitus and dyslipidemia have to be treated orderly. In the pathogenesis of arteriosclerosis and atherosclerosis are known disturbances of the lipid metabolism, the blood coagulation and the metabolism of the arterial wall cells most important. Application of anticoagulants and lipid lowering medicaments did not come up to our expectations. Experiences with animal models and a double blind study (secondary prevention of myocardial infarction) have given good reason for recommending antirheumatic or as we like to say, mesenchyme suppressive drugs.

Based upon factor analysis, initial findings of the risk factors for coronary heart disease are reported, following invesitgations performed on a large number of patho-anatomical cases which were selected for specified criteria. The so-called hypertensive form of arteriosclerosis was demonstrated in the spleen, pancreas, and adrenal gland. It was shown that diabetes mellitus is an influencing factor in arteriolosclerosis in the liver. Several types of arterial hypertension can be differentiated according to clinical features and findings in the heart. Renoparenchymatous and renovascular sclerosis, pyelonephritis, diabetes mellitus, and age are the factors correlated or associated with various types of hypertension. Primary (?) renal hypertension can be differentiated from the secondary (?) TYPE. The discussion suggests that the morphological findings of arteriosclerosis and its complications may be explained, to a certain extent, by the known risk factors of coronary diseases defined by the methods described.

Two outbreaks of Cl. perfringens food poisoning which occurred in Florence during 1976 have been described. The first one involved three hundred primary school children; processed re-heated turkey meat was thought to have been the vehicle of infection in the school meal. The clinical symptoms consisted of mild diarrhoea in all cases and the duration of the illness was about 12 hours. The possible part played by food storage temperature, post-cooking periods and food trolleys in the spread of infection is discussed. The other outbreak interested three people who ate a dish with gravy in a restaurant; one of these suffered severe haemorrhagic enteritis and died after two weeks. Necroscopy was performed and the results of post-mortem examination as well as histological and bacteriological findings certified that the cause of death was severe enteritis (Necrotizing enteritis) in elderly debilitated patient (with diabetes, chronic bronchitis, arteriosclerosis and previously gastroresected).

The proliferation of aortic smooth muscle cells (ASMC) of Wistar rats, impaired by risk factors such as arterial hypertension, diabetes mellitus, atherogenic diet and staphylolysin injections and of normal Wistar rats treated with antirheumatic drugs such as prednisolone and acetylsalicylic acid was investigated. The cells of these animals were cultivated, subcultivated, and in the 2nd subcultures the cell numbers/5 ml medium were counted by means of Coulter Counter, and the cells were incubated with [3H]thymidine and the percentage of labelling in 100 or 1000 counted cells was stated. The effect of risk factors such as LDL and staphylolysin and of antirheumatic drugs such as prednisolone, acetylsalicylic acid, D-penicillamine and chloroquine added to the 2nd subcultures of cultivated ASMC of normal minipigs was investigated by the same method. The proliferation of cultivated ASMC of rats impaired by risk factors was accelerated. The proliferation of cultivated ASMC of rats treated with antirheumatic drugs was inhibited. The proliferation of ASMC of minipigs in the 2nd subcultures was activated by addition of risk factors and inhibited by addition of antirheumatic drugs. Antirheumatic drugs given to the rats and added to the medium of the 2nd subcultures of ASMC of normal minipigs inhibit the acceleration of ASMC proliferation induced by simultaneously given risk factors. The proposal to augment up our arsenal of the hitherto existing preventive and therapeutical measures by the application of antirheumatic drugs based on the experimental models referred to is supported by the result of a limited prospective double-blind-study of a sample of 133 male patients after myocardial infarction. The most remarkable result that the acceleration of the ASMC proliferation, the real pathologic process of arteriosclerosis, is inhibited by the application of antirheumatic drugs, at exactly the same time as the acceleration of the fibroblast proliferation, the real pathologic process in rheumatic diseases--ASMC and fibroblast, both being mesenchymal cells--recommends the use of these drugs in the prevention and therapy of human arteriosclerosis. The surprising result of our in-vivo experiments, that the acceleration of the growth of the ASMC induced by risk factors and the inhibition of the growth induced by antirheumatic drugs persist in the subcultures, is explained by the "selection theory" that there are dissimilar kinds of ASMC in normal arteries and that they react differently.

Although a coronary bypass operation improves the quality of life and possibly prolongs it, a small percentage of patients do not have satisfactory results and require reoperation. From July, 1970, to March 1975, 358 patients underwent coronary bypass for chronic disabling or preinfarction angina. Angina requiring operation recurred in 24 men and 2 women. Hyperlipoproteinemia was present in 19 of the 26 (73%), and 3 patients had early-onset diabetes mellitus. Only 2 of 14 patients with progression of arteriosclerosis were helped by a second operation. Of 7 patients with occluded grafts, local disease, and no progression, 5 were helped by reoperation. Patients with occluded coronary bypass grafts without progression of arteriosclerosis benefit substantially from a second revascularization procedure. Aguarded prognosis must be held, however, for those with progression of arteriosclerosis with hyperlipoproteinemia or juvenile-onset diabetes who undergo reoperation. Patients with initially diffuse disease and graft occlusion also seem to benefit less from a second operation.

The therapy of gout is discussed taking into consideration the concomitant diseases occurring significantly frequently in patients with gout: Hypertension, uric acid-nephrolithiasis, hyperlipoproteinaemia, obesity, premature arteriosclerosis as well as diabetes mellitus. In contrast to other opinions the authors are of the opinion that the dietetic treatment is furthermore of essential importance. It is referred to the still allowed sufficiently great number in the supply of nourishment, in which cases, however, the limitations in the supply of calories, protein or purin bodies, respectively, lipid and carbohydrate do not remain unmentioned. The propositions for the medicamentous treatment essentially correspond to the central therapeutic recommendations. For the acute attack of gout, however, following to the international experiences, the colchicine therapy is more emphasized again. The medicamentous therapy of the asymptomatic hyperuricaemia is to be included into the considerations after full exhaustion of all dietetic and other possibilities in constant increase of the serum-uric acid-level more than 8 mg/dl.

To test the hypothesis that diabetes is a form of accelerated aging, the following observations were made. 1) The incidence rate of diabetes mellitus had its peak at around 50 years of age with a gradually decreasing rate thereafter. This was clearly different from the manner of incidence of such disease as arteriosclerosis which increased with advancing age. 2) 100g of the oral glucose tolerance test performed on elderly subjects aged 60 to 89 years revealed high incidence of abnormal tolerance, 21% diabetic and 53% borderline types. 3) The insulin secretory capacity to glucose load of subjects was not different from that of young and middle-aged subjects from 20 to 49 years old. Therefore, decreased tolerance to glucose load could not ba ascribed to deficient insulin secretion. 4) No abnormality of glucagon response to glucose load was found in the old. 5) Serum beta-N-acetylhexosaminidase activity was not increased in elderly subjects, again contrasting with the increased activity found in diabetics. 6) Both glycolytic and gluconeogenic enzyme activities were decreased in the liver of aged rats. 7) No specific abnromality in insulin secretory response was observed in Werner's syndrome which might be considered to be a model for aging. All the above observations do not support the aforementioned hypothesis. Abnormality of glucose tolerance frequently observed in elderly subjects appears to be caused by other pathogenesis than diabetes mellitus.

Regional cerebral blood flow (rCBF) was measured by 133Xe inhalation in 46 normal volunteers, aged 21 to 63 years, and 14 neurologically asymptomatic subjects above age 40 with risk factors for atherothrombotic stroke, including hypertension, diabetes mellitus, and hyperlipidemia. In normal volunteers, there was diffuse and progresive reduction of gray matter flow and weight as well as increases of cerebrovascular resistance (CVR) with advancing age. Reduction of gray matter flow with advancing age appears to be attributed in part to neuronal atrophy and in part to cerebral arteriosclerosis. Regional increases of CVR and reduction of gray matter flow with advancing age were most evident in the middle cerebral arterial (MCA) distribution and were enhanced by the association of risk factors. Development of cerebral arteriosclerosis with age and/or risk factors appears to be most evident in MCA distribution.

Out of 769 patients with arterial diseases, reconstructive surgery was performed on 100 limbs of 79 patients for arteriosclerosis. The overall patency rate was 59 per cent over a period of 3 to 8 years. Long-term patency was influenced by the condition of the run-off arteries, the site of the operation, and the method of surgery. No relation was found between patency rate and hypertension, cardiac insufficiency, total serum cholesterol, diabetes mellitus, or age. The survival rate was 62 per cent at 5 years and 48 per cent at 7 years. These rates were significantly poor (p less than 0.001), compared with those in the normal population. Mortality was related to the degree of hypertension, with cardiac and renal failure being responsible for 72 per cent of deaths. Aggressive reconstruction may be indicated in cases with hypertension of stage 2 or below based on the WHO classification. However, especially in patients with associated diabetes mellitus close long-term observation of the cardiovascular system is necessary.
