Hyperuricaemia was present in 18 out of 73 men with untreated mild hypertension and was related significantly to alcohol intake, serum aspartate transaminase activity, and obesity. In the whole group the mean serum urate concentration correlated highly significantly with alcohol intake and activities of serum aspartate and alanine transferases but not with ponderal index, serum creatinine concentration, age, or blood pressure. Hypertension and hyperuricaemia are related at least in part through their common association with frequent alcohol use. A serum urate concentration exceeding 0.5 mmol/l (8--4 mg/100 ml) in a man with untreated hypertension is highly suggestive of heavy alcohol consumption. There was no evidence that hyperuricaemia had a deleterious effect on renal function.

Normotensive, Sprague-Dawley (S-D) and spontaneously hypertensive (SH) rats were subjected to aortic ligature. The systolic blood pressure of S-D rats was increased by +/- 80 mm Hg, whereas the blood pressure of SH rats with pre-existent hypertension increased only slightly, +/- 9 mm Hg. The S-D rats developed myocardial and renal infarcts as well as polyarteritis nodosa; the SH rats developed testicular and microadrenocortical infarcts only. Aortic-ligated S-D rats had elevated creatine phosphokinase, serum glutamic-oxaloacetic transaminase, serum glutamic-pyruvic transaminase, and lactic hydrogenase levels and manifested hyperglycemia, hypercholesterolemia, and elevated blood urea nitrogen (BUN) levels. Corticosterone levels increased in aortic-ligated S-D rats but decreased in SH rats. Collateralization about the site of aortic ligature appeared to be the same in both strains. It is suggested that the acutely induced hypertension in S-D rats rather than SH rats and differences in adrenal steroidogenesis between the two strains would best account for the dichotomous cardiovascular response to aortic constriction.

The levels of five enzymes were examined in the urine and the serum of pregnant women. They included leucine aminopeptidase (LAP), alkaline phosphatase (AP), N-acetyl-beta-glucosaminidase (ABG), lactic acid dehydrogenase (LDH) and glutamic-oxaloacetic transaminase (GOT). After establishing the normal curve and upper confidence limits in healthy pregnant patients (138 examinations in 52 women), the the enzymes were examined in the urine and the serum of 21 severe and 23 mildly toxemic cases. The mean urinary levels of ABG, AP and LAP in the severe cases were significantly higher than in the normals, and by examining all three enzymes, at least one of them was found to be above the upper confidence limit in 95% of the severely ill women. The changes did not show up early enough to form a good diagnostic and prognostic sign in moderate pregnancy-induced hypertension, but severe kidney damage may be revealed earlier than by the regular kidney function tests, and patients with a bad remote prognosis can be singled out by this method.

The clinical behaviour and mean peak serum aspartate aminotransferase (SGOT) values of 106 patients admitted to a coronary care unit with acute myocardial infarction who displayed acute systolic hypertension were studied. Another 106 normotensive patients with acute myocardial infarction acted as controls. Neither group had established hypertension. The mortality rate, incidence of cardiac failure, major arrhythmias, and mean peak SGOT were significantly greater in the hypertensive group, within which the duration of hypertension was correlated with mean peak SGOT levels--through there was no definite relation between the height of systolic or diastolic pressure and SGOT. Transient systolic hypertension after acute myocardial infarction was therefore associated with a relatively poor prognosis, but our observations suggest that patients with a systolic blood pressure of at least 170 mm Hg might benefit from early hypotensive treatment.

The relation between alcohol consumption and blood pressure is well recognized, and advice to reduce alcohol plays an important part in the management of hypertensive patients. We have evaluated the effectiveness of this advice in a randomized, controlled, single-blind clinical study. After a 2-week run-in period, hypertensive men regularly consuming more than 20 units/wk (1 unit = 10 g) of alcohol were randomly assigned either to the "advice" or control group and were seen at 2-week intervals over an 8-week study period. The outcome measures were: reported alcohol consumption (1-week retrospective diary), markers of alcohol consumption (serum gamma-glutamyl transpeptidase, aspartate aminotransferase, uric acid, mean corpuscular volume), and blood pressure (sitting and standing). Over 18 months, 67 men who drank more than 20 units/wk of alcohol were seen. Twenty-six either were excluded, refused to participate, or dropped out due to nonattendance. Forty-one patients completed the study. After intervention, reported alcohol consumption fell from 60 units/wk to around 30 units/wk in the advice group, whereas it remained between 50 and 60 units/wk in the control group (analysis of variance [ANOVA] F = 7.1, p less than 0.05). This was accompanied by falls in gamma-glutamyl transpeptidase (20.9%) and aspartate aminotransferase (18.1%), but no significant changes were seen in the control group. Standing diastolic blood pressure fell significantly in the advice group (from 101.5 mm Hg to 96.3 mm Hg) compared with the control group (ANOVA F = 4.8, p less than 0.05). The results suggest that advice to reduce alcohol consumption is a useful form of treatment for hypertensive patients who drink excessively.

Predictors of the development of hypertension were examined in a 10-year follow-up study of normotensive Japanese adults. Subjects (n = 265), aged 30-69 years at entry, normotensive and with no past history of antihypertensive treatment at entry, were studied in terms of the relationship of various physical, biochemical, dietary, and lifestyle data to the subsequent development of hypertension (defined as systolic blood pressure (SBP) more than 140 mmHg and/or diastolic blood pressure (DBP) more than 90 mmHg and/or starting antihypertensive treatment) with analysis accomplished using univariate and multivariate life table methods. Univariate analyses by the generalized Wilcoxon test showed significantly higher incidence of hypertension in those subjects with SBP 120 mmHg or more (p < 0.001), DBP 75 mmHg or more (p < 0.001), serum glutamate oxaloacetate transaminase (GOT) 20 KU or more (p < 0.001), serum glutamate pyruvate transaminase (GPT) 15 KU or more (p < 0.001), serum gamma-glutamyl transpeptidase (gamma-GTP) 10 IU/l or more (p < 0.001), age 50 or older (p = 0.002), body mass index 22 kg/m2 or more (p = 0.012), and serum creatinine less than 1.2 mg/dl (p = 0.020) than in the other subjects. Multivariate analysis by the Cox proportional hazards model confirmed that relatively higher SBP (p < 0.001), lower serum creatinine (p < 0.001), higher gamma-GTP (p = 0.002), and higher age (p = 0.041) were independent and significant predictors of future hypertension.

The aim of this study was to investigate the usefulness of serum bilirubin, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (APh) and real time ultrasonography (US) in distinguishing between gallstone and non gallstone related acute pancreatitis (A.P.). The second aim was to evaluate whether or nor there was biliary tract hypertension. Both aims were designed in order to evaluate them in the early stage of A.P. Two Groups of patients were studied. Group 1--gallstone related A.P., 63 pts. Group 2--Non gallstone related A.P. 21 pts. Fifty nine (93.6%) of Group 1 and 11 (52.3%) of Group 2 had surgical confirmation. In the other, the diagnosis was based on US and C.T. Blood samples were taken during the three days after admission for biochemical test and US was performed within the same period. Statistical evaluation and Student's t test were used. Biochemical test: when the cut off level was expressed by the upper limit of normal (ULN), the highest diagnostic sensibility was (table 1): ALT 85.7%, APH 80.9%. AST 71%, bilirubin 65%. When the cut off level was chosen at twice the ULN (Table 1), the sensibility was: ALT 61.9%, bilirubin and AST 47%, APh 30%, Group 2 (Table 2) values higher than the ULN were: AST 42.8%, bilirubin 33%, ALT 19%, APh 14.2%. The differences between the two Groups were statistically significant: APh and bilirubin P less than 0.001, ALT less than 0.05 m AST, NS. Ultrasonography: Group 1: gallstones were detected in 96.6% (58/60). Biliary tree was not visualized in 10 (15.8%), diagnosed as normal in 38 (60.3%) and pathologic (dilatation and/or lithiasis) in 15 (23.8%).(ABSTRACT TRUNCATED AT 250 WORDS)

Cerebrospinal fluid was tested for several enzymes (CPK, AST, GGTP, BP, BG, AK) in 97 patients with generalized meningococcal infection with prevalent CNS affliction. Marked changes were detected even in the absence of clinical signs of cerebral lesion that was typical only of meningococcemia. Nevertheless, most pronounced changes were observed in a group of patients with cerebral edema and swelling. The changes in cerebrospinal fluid enzyme levels coincided with a reduced glucose and increased protein contents. In these cases, CSF hypertension increased CSF pressure to maximal levels. Most informative indices were singled out and their levels characteristic of acute phase of the disease established.

The efficacy of sustained-release propranolol 160 mg (Inderal LA), bendrofluazide 5 mg and the combination preparation Inderex (bendrofluazide 5 mg and Inderal LA) in the treatment of hypertension was investigated. Twenty-one patients over a wide age range were studied, as it was of particular interest to find whether differing responses across a range of age groups might exist 24 hours post-dosing. Blood pressure control was greater with Inderex than with either Inderal LA or bendrofluazide. No significant difference between different age groups on the three treatments was demonstrated. There was some evidence, not statistically significant, suggesting potassium values to be lower on bendrofluazide and on Inderex. Serum glutamate oxaloacetate transaminase (SGOT) values were raised on bendrofluazide. Inderex is more effective in lowering blood pressure than either bendrofluazide or Inderal LA alone, and as a single capsule given once daily encourages compliance in comparison with combination treatments.

The study was carried out on 23 samples of amniotic fluid taken (by amniocentesis) between 35th and 39th week from pregnant women with arterial hypertension (13 cases of hypertension induced by pregnancy, 5 cases of primary hypertension and 5 cases of hypertension accompanying renal diseases). Seven women undergoing the study gave birth to newborns with symptoms of delayed intrauterine growth below 16 centiles (group examined), 16 mothers gave birth to eutrophic babies (control group). The amniotic fluid of the two groups was studied for the following biochemical indexes: alanine and aspartate aminotransferase alkaline total and thermostabile phosphatase, ceruloplasmin, alpha-amylase, general protein, beta-lipoproteins, cholesterol, uric acid, urea and creatinine. No significant changes were found in the parameters determined between the group examined and the control group.
