Both naturally occurring disease processes and experimental models of human disease in the Mongolian gerbil were reviewed. The gerbil was highly susceptible to cerebral infarction following unilateral ligation of one common carotid artery and was useful in studies of the pathogenesis of stroke. Spontaneous epileptiform seizures mimicked those of human idiopathic epilepsy, and both seizure-sensitive and resistant strains have been bred. Perhaps because of its more efficient nephron, the gerbil accumulated four to six times as much renal lead as the rat, and the gerbil has been proposed as an experimental model of lead nephropathy. On standard diets, about 10% of the animals became obese, and some showed decreased glucose tolerance, elevated serum immunoreactive insulin and diabetic changes in the pancreas and other organs. Some breeders exhibited hyperactivity of the adrenal cortex associated with hyperglycemia, hyperlipidemia and degenerative vascular disease. Although dietary supplements of cholesterol were toxic and did not induce atherosclerosis, the gerbil was useful in other studies of cholesterol absorption and metabolism. Spontaneous, insidious periodontal disease became evident after about 6 months on standard diets, and dental caries were induced by cariogenic diets or by pathodontic streptococci. Spontaneous neoplasia occurred in 8.4--24% of gerbils, usually after 2 years of life. Adrenal cortical, ovarian and cutaneous tumors were the most consistently reported neoplasms.

In a consecutive series of 11 young patients with clinical evidence of cerebral infarction, platelet function and plasma lipid levels were examined. The results show that increased platelet aggregability characterizes the patient group as a whole. Hyperlipidemia was frequently found, and the number of heavy smokers was high. It is suggested that all younger patients with cerebrovascular disease are examined with regard to these presumed risk factors.

1. There were significant correlation between hyperlipidemia and obesity, hypertension, abnormal ECG and abnormal eyeground. 2. The incidence of cerebral hemorrhage was closely associated with hypertension but not with hyperlipidemia. 3. It was proved that hypertension with both hyper-Ch and hyper-TG was highly related to the development of cerebral infarction. 4. It seemed that the incidence of myocardial infarction and angina pectoris was related to hypertension with hyper-Ch. 5. Therefore, the present study suggested that the control of hypercholesterolemia and hypertriglyceridemia was useful for the prevention of cerebro-cardiovascular disease.

Twenty-six patients under 20 years of age having cerebrovascular disease were studied from 1968 to 1972. Common risk factors such as hypertension, diabetes mellitus, hyperlipidemia and heart disease were not present. Angiographical study showed a variety of abnormalities. No consistent defect was present. There was a high incidence of pyrexia and convulsions in the early stages of stroke and it appears possible that some form of arteritis might have been important in the production of the cerebral infarction.

A report is made here on a rare case in which occurrence of multiple cerebral aneurysm was observed after radiotherapy. The case was that of a female aged 51 who was hospitalized with the chief complaint of consciousness disorder. The patient was discharged from the hospital 1 year before, after undergoing subtotal extirpation of a tumor through the transsphenoidal sinus in a case of pituitary adenoma, and post-operative radiotherapy (topical 50 Gy). Mild hyperlipidemia associated with hypothyroidism was observed by blood biochemical test during the patient's hospitalization, and multiple cerebral infarction was also observed by CT scanning and MR imaging. Therefore, conservative treatments including intensified endocrine-supplementing treatment, centering on thyroid hormone, were attempted. The patient's thyroid gland function and hyperlipidemia improved but the consciousness disorder persisted. Exacerbation of the consciousness disorder occurred suddenly 6 weeks after the patient's hospitalization. Subarachnoid hemorrhage and hydrocephalus were observed by CT scanning. Cerebral angiography detected a saccular aneurysm in the trifurcation of the right middle cerebral artery, 3 fusiform aneurysms in the periphery of the right middle cerebral artery, 2 fusiform aneurysms in the posterior cerebral artery and irregularity of wall width in the central artery including the terminal region of the internal carotid artery. These findings were not observed at the initial hospitalization and were considered to have been formed newly afterwards. Further, these findings were observed unexceptionally in all the radiated fields. The patient died 8 weeks after hospitalization, and no autopsy finding was obtained. From the above, we presumed that radiation vasculopathy caused by the radiation therapy made one year previously, had led to the formation of multiple cerebral aneurysms.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of alcohol as a risk factor for cerebral infarction and hemorrhage has been assesed in 200 middle-aged and elderly stroke patients and 200 controls matched for age, sex and hospital admission date. Computed tomographic brain scans were done in all but 10 of the stroke patients. Alcohol intake was reckoned on the 12 months preceding hospitalization and expressed in grams daily according to a standard nomogram. The Michigan Alcoholism Screening Test was used for the diagnosis of alcoholism. Cerebral infarction was present in 59% of the stroke patients and cerebral hemorrhage in 9%. The role of alcohol as risk factor for stroke proved to be small (Odds Ratio 1.86) and was practically lost after adjustment for the most common risk factors for cerebrovascular disorders (previous strokes, arterial hypertension, diabetes, obesity and hyperlipidemia). Our findings seem to suggest that alcohol is not an independent risk factor for stroke in the middle-aged and elderly. The data are, however, preliminary and are discussed in the light of methological problems.

The aim of this study is to describe the clinical characteristics and the pathological mechanisms of carotid transient ischemic attacks (TIA) in 117 patients which were hospitalised for such symptoms. Our results show a male predominance, except for age group under 40 and over 79 years. The principal cardiovascular index and risk factors are: arterial hypertension, smoking, hyperlipidemia, vascular intermittent claudication and hematocrit greater than 46%. Amongst our patients, 17% with hemispherical and mixed TIAs had a cerebral infarction proved by CT-Scan, the recent aspect and localisation of which were compatible with symptoms. The atherosclerotic causes are more frequently associated with mixed and retinal TIAs than hemispheric TIAs. This fact may be attributed to a larger proportion of stenotic atherosclerotic lesions by mixed TIAs than hemispheric ones. The cardiac embolic pathogenic mechanism is responsible for 11% of TIAs if considered individually; of 5% if associated with carotid atherosclerosis.

We investigated the anticardiolipin antibody (ACA) in a series of patients with cerebral infarction without systemic lupus erythematosus (SLA). Clinical and laboratory data were assessed from a series of 250 non-SLE patients with cerebral infarction who visited our clinic from 1988 to 1990. The concentration of anticardiolipin IgG antibody was measured by an enzyme-linked immunosorbent assay technique. An elevated ACA level was defined as one which was greater than 3 standard deviations above the mean level for normal controls. We examined the CT findings and risk factors for stroke such as hypertension, diabetes mellitus, hyperlipidemia and cardiac disease. Laboratory data such as the platelet count, the presence of lupus anticoagulant and a biologic false-positive test for syphilis were also investigated. Among the 250 patients with infarction, IgG ACA was detected in 22 (8.8%). There was no significant difference in incidence of ACA between the patients with cerebral thrombosis and those with cerebral embolism. On CT scan, multiple cerebral infarcts were noted in 18 of the 22 patients. As regards the location of the infarct, the cerebral cortex together with the basal ganglia was more common than isolated lesions of the cortex or basal ganglia. Concerning the risk factors for stroke, hypertension was noted in 12, diabetes mellitus in 2, hyperlipidemia in 2 and cardiac disease in 2. Lupus anticoagulant and thrombocytopenia were not detected in any of the cases. A biologic false-positive test for syphilis was observed in one case. Dementia was present in 12 of the 22 patients.(ABSTRACT TRUNCATED AT 250 WORDS)

A 53-year-old man was suffered from progressive effort angina. Coronary angiogram revealed complete obstruction of the left anterior descending artery with collaterals from posterior descending artery. The essential thrombocythemia was diagnosed from platelet count over 1,000,000/mm3 with bleeding tendency. And hyperlipidemia was not observed. After the platelet count was reduced into normal range by administration of Melphalan, coronary artery bypass grafting using the left internal thoracic artery was performed successfully. The main cause of his coronary artery disease was thought to be secondary to the essential thrombocythemia as his past history included cerebral infarction secondary to transient thrombus formation in the common carotid artery which was confirmed with cerebral angiography. He has been on melphalan, warfarin and dipyridamol therapy after the operation without chest symptom.

The records of 36 patients (37 eyes) with central retinal artery occlusion (CRAO, 19 patients, 19 eyes), branch retinal artery occlusion (BRAO, 15 patients, 16 eyes), and cilioretinal artery occlusion (CIAO, 2 patients, 2 eyes) were reviewed with respect to underlying systemic disorders. Hypertension was the most common disorder (58%). Half of the patients had cardiovascular disorders including ischemic heart disease, valvular disease, atrial fibrillation, internal carotid artery obstruction, and atrial myxoma. Seventeen percent of the patients had diabetes mellitus, and 8% had hyperlipemia. Cerebral infarction was detected in a quarter of the patients. The incidence of the disease was one CRAO patient per 1,000 outpatients. Age distribution showed a peak in the seventh decade. Men were twice more frequently affected than women. Right eyes were more commonly involved.
