Acute glomerulonephritis is a distinct clinical entity, more frequently found in younger age. We report 69 patients with AcGN (25 female and 44 male) mean age 26 years (range 15-58). The disease is clinically characterized with hypertension (57%), edema (59%) and oliguria (35%). Urine analysis showed microhaematuria/proteinuria (36%) and micro/macrohaematuria alone in 89%, while azothaemia was observed in 16% pts, and decreased serum complement levels in one third of patients, more often decrease of C3 (33%) than C4 (15%). Initial infection of the upper respiratory tract was seen in 65%, pneumonia in 8%. In 25% of pts. there were no data of previous infection. Cultures of pharyngeal smear revealed. Streptococcus only in 2 pts. Elevated AST titer was found in 32% pts. Eleven kidney biopsies were made, and histological examination showed 2 normal findings, 6 mesangioproliferative GH, 2 endocapillary GN and 1 membranoproliferative GN. Follow ups have showed urinary abnormalities in 25% of pts., without developing renal failure.

Abnormal liver tests, as well as morphological changes in the liver, are frequent among obese patients. Other frequent disturbances are visceral fat accumulation, insulin resistance, non-insulin-dependent diabetes mellitus (NIDDM), hypertriglyceridemia, and hypertension; these are set of aberrations known as the metabolic syndrome. In order to investigate a possible relationship between the metabolic syndrome and impaired liver status we examined associations between liver tests, metabolic variables (insulin, glucose, and triglycerids), body composition and nutrition in 1,083 men (BMI 28.8-63.8 kg/m2) and 1,367 women (BMI 26.7-68.0 kg/m2) in the ongoing intervention study of Swedish Obese Subjects (SOS). Standard biochemical techniques were used to assess liver status and metabolic variables. Lean body mass (LBM) and masses of visceral and subcutaneous adipose tissue (AT) were estimated by means of computed tomography (CT) calibrated anthropometric equations. In both genders aspartate aminotransferase and alanine aminotransferase were, or tended to be, positively correlated to fasting serum insulin, visceral AT (women), and alcohol intake. In women, the aminotransferases were also correlated with fasting blood glucose. In both genders alkaline phosphatase was, or tended to be, positively associated with visceral AT, insulin (women), and glucose. Bilirubin was negatively correlated to insulin and visceral AT in men and women. Additional multivariate analyses indicated that alcohol had less explanatory power than serum insulin for the examined liver tests, especially among women. These results suggest that pathological liver tests in the obese may represent an expression of the metabolic syndrome.

A 79-year-old female was admitted to our hospital because of a malignant pleural effusion following mastectomy 4 years ago. In the patient's history arterial hypertension and previous inferior myocardial infarction have been known. Two doses of 20 mg mitoxantrone were installed intrapleurally at an interval of 4 weeks. Six hours after the second mitoxantrone application and the patient had increasing dyspnea with consecutive left heart failure, pulmonary congestion, and a drop of blood pressure. The white-cell count was 14800/mm3. The levels of creatinine phosphokinase (CPK), lactate dehydrogenase (LDH) and serum aspartate aminotransferase (SGOT) were in the normal range. Transthoracic echocardiography showed concentric left ventricular hypertrophy and a markedly decreased fractional shortening, but no left ventricular dilatation. The electrocardiogram showed newly appeared down-sloping ST-segments and inverted T-waves. Clinical recovery was achieved after 6 days by application of oxygen, dobutamine and furosemide followed by angiotensin converting enzyme inhibition and digitalis. In the echocardiographic control examination 14 days later left ventricular function had normalized. The changes of electrocardiogram normalized 4 weeks later.

Urinalysis was carried out in 231 inpatients with alcohol dependence syndrome (215 males and 16 females). Fifty-nine patients (25.5%) showed proteinuria, 97 (42.0%) showed glucosuria, and 62 patients (26.8%) showed hematuria on admission. A total of 135 out of 231 patients (58.4%) showed abnormal urinalysis. Proteinuria was related to high blood pressure, high serum glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase, lactate dehydrogenase, uric acid, and triglyceride levels, and high urinary amylase concentration. Glucosuria was related to high serum glutamic-oxaloacetic transaminase concentration and a history of gastrectomy. Hematuria was related to high age and high urinary amylase levels. By chi-square test, there was a significant correlation between proteinuria and hematuria (p < 0.001) and between hematuria and glucosuria (p < 0.001), but no correlation was found between proteinuria and glucosuria. The incidence of diabetes mellitus was 10.8% (25 out of 231 patients), but transient hyperglycemia was observed in some patients without diabetes mellitus on admission. Elevated hemoglobin A1, hemoglobin A1c, and fructosamine concentrations were observed in patients with either impaired glucose tolerance or transient hyperglycemia, which suggested the presence of persistent hyperglycemia before admission. On discharge, only 12 out of 198 patients (6.1%) showed abnormal urinalysis. We report that heavy ethanol consumption induces transient abnormal urinalysis results in Japanese alcoholics.

Anoectochilus formosanus Hay. and Gynostemma pentaphyllum Makino are popular folk medicines that have been used for treating hepatitis, hypertension and cancer in Taiwan. Our previous studies showed that these crude drugs exert antiinflammatory activity and hepatoprotective activity against CC14-induced liver damage. In this study, the antioxidant effect of these crude drugs and their hepatoprotective activity on acetaminophen-induced liver injury in rat was evaluated. Our results suggest that A. formosanus and G. pentaphyllum do have antioxidant effects. On acetaminophen-intoxicated model, the increased levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) by acetaminophen administration were reduced by treatment with these two herbs. In histological observation, gross necrosis in the centribular area, sinusoidal congestion, infiltration of the lymphocytes and Kupffer cells around the hepatic central vein, and loss of cell boundaries and ballooning degeneration were reduced with herbal treatment. However, the effect of A. formosanus and G. pentaphyllum is biphasic. Methanol extract (100 and 300 mg/kg) and water extract (300 and 500 mg/kg) of A formosanus and water extract (100, 300 and 500 mg/kg) of G. pentaphyllum enhanced the recovery of liver injury while treatment with 500 mg/kg of A. formosanus methanol extract resulted in serious hepatic injury.

We investigated whether the imposition of chronic alcohol in hypertension leads to greater biochemical and cellular abnormalities of the myocardium than those arising in normotension. Fifteen-week-old spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats were fed ethanol-containing diets for six weeks. Particular attention was focused on the composition of contractile proteins identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), fractional rate of protein synthesis, and synthesis rates relative to RNA (RNA activity) or DNA (cellular efficiency). In addition, myocardial enzymes and adenine nucleotides were measured. In both SHR and WKY rats chronic ethanol caused a general decrease in the contents of all nine contractile proteins with myosin heavy chain predominantly affected. Fractional rates of mixed (i.e., total) and myofibrillary proteins remained unaltered in both WKY rats and SHR, as were cellular efficiencies. The RNA activity was significantly reduced in ethanol-treated SHR but not in WKY rats. In ethanol-treated SHR, cardiac creatine kinase (CK) and malate dehydrogenase (MDH) activities were increased, AMP levels were elevated, whilst ATP levels and the energy charge were reduced. In WKY rats, the only significant change related to increased aspartate aminotransferase activities in response to alcohol feeding. Although there were only subtle differences between the response of the normotensive and hypertensive rats due to ethanol dosage, the reduced ATP levels and increased CK and MDH activities in SHR may reflect a greater susceptibility to ischaemic damage. Reduced contractile protein content, particularly myosin heavy chain, may contribute to contractile defects, a common feature of subclinical and clinical alcoholic cardiomyopathy.

This review addresses the general hypothesis that the pathogenesis of preeclampsia and eclampsia are related to an imbalance of increased oxidative stress and lipid peroxidation coupled with a deficiency of antioxidant protection. Accordingly, this study was initiated to assess total antioxidant status and free-radical activity in preeclampsia and eclampsia. The patients studied were 44 healthy pregnant women and 45 women with hypertension classified as having preeclampsia (n=27), and eclampsia (n=18). The serum levels of lipid peroxide were significantly increased (p<0.0001) and antioxidant enzyme activities (superoxide dismutase and glutathione levels) in erythrocytes were significantly decreased (p<0.0001) in women with preeclampsia and eclampsia compared with the controls. The groups of preeclampsia and eclampsia had similar values of catalase activities as the controls (p>0.05). There were no correlations between serum levels of lipid peroxide and antioxidant enzyme activities or systolic-diastolic blood pressure of pregnant women with preeclampsia and eclampsia. The mean systolic and diastolic blood pressure, the serum lactate dehydrogenase (LDH) and aspartate transaminase (AST) levels of preeclamptic and eclamptic women were high, whereas haemoglobin (Hb), Hematocrit (Htc) and platelet levels were lower than those of the control subjects (p<0.0001). There were no differences in mean gestational week, whereas the mean age of eclamptic women was lower than that of the other two groups (p<0.001). The serum levels of Alanine-transaminase (ALT) and urea in eclamptic women were significantly higher compared with the other two groups (p<0.0001), whereas creatinine levels were lower than those of the other two groups (p<0.05). Our findings give support to those few studies considering lipid peroxidation as an important factor in the pathogenesis of preeclampsia and eclampsia. Further studies are needed to clarify the relations between lipid peroxidation and antioxidative function and their pathophysiological significance in preeclampsia and eclampsia.

HELLP syndrome is a serious, life-threatening form of pre-eclampsia with a typical laboratory triad. The incidence of the disease is reported as being 0.17-0.85% of all live births. There has been, to date, neither reliable early recognition nor effective prevention of HELLP syndrome. As a result of endothelial dysfunction, activation of intravascular coagulation occurs with fibrin deposition in the capillaries and consecutive microcirculation disorders. The disease manifests itself on average between 32-34 weeks' gestation. HELLP syndrome will occur postpartum in up to 30% of the cases. The clinical cardinal symptom of the disease is right upper quadrant pain or epigastric pain accompanied with nausea, vomiting and malaise. In 20% of the cases with HELLP syndrome there is no hypertension and 5-15% of the pregnant patients present a low level of proteinuria or none at all. The early recognition of hemolysis is most sensitively managed by the determination of the serum haptoglobin. The increase of the aspartate transaminase (AST) and the alanine transaminase (ALT) often precedes a decrease in platelets. The course of HELLP syndrome is incalculable. It is universally agreed that a pregnancy from 32-34 weeks should be immediately delivered. Before 32-34 weeks, expectant management is generally possible in a perinatal center. The frequency for a repeated hypertensive disease in pregnancy ranges from 27% to 48%.

Licorice, the root of Glycyrrhiza spp. (Fabaceae), has been used since ancient Egyptian, Greek, and Roman times in the West and since the Former Han era (the 2nd-3rd century B.C.) in ancient China in the East. In traditional Chinese medicine, licorice is one of the most frequently used drugs. In Japan, the oldest specimen of licorice introduced from China in the middle of the 8th century still exists in Shosoin, the Imperial Storehouse, in Nara. Extracts of licorice were recommended as a remedy for gastric ulcer by Revers of the Netherlands in 1946, which was soon withdrawn owing to its side effects. Carbenoxolon sodium, glycyrrhetinic acid (GA) hemisuccinate Na, was prepared from licorice to treat peptic ulcer in the UK. In Japan for the past 60 years, a glycyrrhizin (GL) preparation under the name of Stronger Neo-Minophagen C (SNMC) has been used clinically as an antiallergic and antihepatitis agent. GL and GA sometimes induce edema, hypertension, and hypokalemia in patients treated with higher doses and long-term administration. The mechanism of this side effect, pseudoaldosteronism, has been explained as due to the 11-hydroxy-steroid dehydrogenase inhibitory activity of GL and GA. The excess of endogenous cortisol produced combines with the renal mineral corticoid receptor, which promotes an aldosterone-like action. GL and GA reduce alanine transaminase (ALT) and aspartate transaminase (AST) values in the serum. This hepatoprotective effect has recently been explained as the inhibitory effects of GL and GA on immune-mediated cytotoxicity against hepatocytes and on nuclear factor (NF)-kappa B, which activates genes encoding inflammatory cytokines in the liver. To exclude the side effects and enhance the therapeutic activities, chemical modification of GL and GA has been performed. Deoxoglycyrrhetol (DG), homo- and heteroannular diene homologs of dihemiphthalates, showed a remarkable improvement in antiinflammatory, antiallergic, and antiulcer activities in animal experiments. Immunomodulating effects of GL, GA, and DG derivatives, which induce interferon-gamma and some other cytokines, have been demonstrated in relation with their antiviral activities. Antiinflammatory, antitumorigenic, and antimalarial effects of licorice flavonoids have also been investigated.

The authors performed a survey in 3,615 Shinawatra employees aged 18-60 years to determine the abnormalities found with routine checkup. The annual checkup included: history taking. anthropometric measurement, physical examination, complete blood count, urine analysis, chest roentgenography, blood chemistry (fasting blood glucose, BUN, creatinine, uric acid, AST/ALT, cholesterol, triglyceride and HDL-cholesterol). The prevalence of abnormalities with management change detected by complete blood count, urine analysis was low and we did not recommend the routine use of complete blood count and urine analysis. The prevalence of hypertension was more common in males and the prevalence increased sharply after the age of 25 years in males and 40 years in females. The prevalence of abnormalities of BUN, creatinine (both males and females) and uric acid (in females) was very low. There was high prevalence of high AST/ALT which suggested hepatitis in our population, and the prevalence was more common in males beginning at a young age. Diabetes mellitus was more common in males especially after the age of 45 years. Chest roentgenography abnormalities were found in 9.4 per cent and the prevalence of abnormalities increased with age and was common after the age of 44 years. Most of the abnormalities found by chest roentgenography were pulmonary infiltration and cardiomegaly. The authors' findings did not recommend the routine use of complete blood count, urine analysis, fasting BUN and creatinine. We recommend routine blood pressure measurement in males aged 25 years or more and in females aged 40 years or more. We suggest routine blood cholesterol measurement in both sexes, blood triglyceride measurement in males aged 25 years or more and fasting blood sugar tests in males aged more than 44 years, chest roentgenography in males and females after the age of 45 years.
