Prevalence of Proteinuria and Hematuria in a Rural Population in the Southwest of Iran.

Acute and chronic kidney diseases are common and are associated with the risk of kidney failure. Early detection of these disorders prevents their progression to kidney damage in later stages. The aim of this study was to investigate the prevalence of proteinuria and hematuria in a rural population in Yasuj, Iran. In this cross-sectional study, 676 people (350 females and 326 males) participated. People with positive dipstick test results entered the second screening and the urinary protein-to-creatinine ratio (UPCR) was measured. People with UPCR ≥150 mg/g were evaluated for demographic and biochemical indicators. In the initial screening, 72 subjects (10.6%) tested positive by the dipstick test with trace proteinuria or higher. The UPCR results showed that this ratio was above 150 mg/g in 42 patients (6.2%), which was approximately equivalent to more than 150 mg of protein excreted per day. There was no significant relationship between the prevalence of proteinuria and the demographic and biochemical markers. Briefly, it seems that the prevalence of proteinuria found by the dipstick test was similar to that in other parts of the world. However, according to the UPCR index, the percentage of proteinuria was significantly higher than in other studies. Because of the unknown mechanism of proteinuria, more studies based on genetic tests and kidney biopsies are needed to determine the causes of proteinuria.

The effect of hydro alcoholic extract of Juglans regia leaves in streptozotocin-nicotinamide induced diabetic rats.

Phytotherapy has been achieved to maintain glycemic control in patients with diabetes mellitus. The present study was conducted to evaluate the antihyperglycemic properties of the Juglans regia leaf extract in streptozotocin-nicotinamide induced diabetic rats. Nicotinamide was injected intraperitonealy (i.p.) 15 min before the injection of Streptozotocin (i.p.). One week after induction of diabetes, oral treatment started with extract of Juglans regia and Metformin and continued for 4 weeks. Fasting blood sugar, body weight, serum lipids and insulin level were measured in different groups. A significant reduction of glucose, HbA1c, total cholesterol and serum triglycerides were detected after 4 weeks in rats treated with Juglans regia leaves compared to the control groups. Thus, Juglans regia extract treatment showed potential hypoglycemic and hypolipidemic effects in type 2 diabetic rats.

Frequency and severity of myocardial perfusion abnormalities using Tc-99m MIBI SPECT in cardiac syndrome X.

BACKGROUND: Cardiac syndrome X is defined by a typical angina pectoris with normal or near normal (stenosis <40%) coronary angiogram with or without electrocardiogram (ECG) change or atypical angina pectoris with normal or near normal coronary angiogram plus a positive none-invasive test (exercise tolerance test or myocardial perfusion scan) with or without ECG change. Studies with myocardial perfusion imaging on this syndrome have indicated some abnormal perfusion scan. We evaluated the role of myocardial perfusion imaging (MPI) and also the severity and extent of perfusion abnormality using Tc-99m MIBI Single Photon Emission Computed Tomography (SPECT) in these patients. METHODS: The study group consisted of 36 patients with cardiac syndrome X. The semiquantitative perfusion analysis was performed using exercise Tc-99m MIBI SPECT. The MPI results were analyzed by the number, location and severity of perfusion defects. RESULTS: Abnormal perfusion defects were detected in 13 (36.10%) cases, while the remaining 23 (63.90%) had normal cardiac imaging. Five of 13 (38.4%) abnormal studies showed multiple perfusion defects. The defects were localized in the apex in 3, apical segments in 4, midventricular segments in 12 and basal segments in 6 cases. Fourteen (56%) of all abnormal segments revealed mild, 7(28%) moderate and 4 (16%) severe reduction of tracer uptake. No fixed defects were identified. The vessel territories were approximately the same in all subjects. The Exercise treadmill test (ETT) was positive in 25(69%) and negative in 11(30%) patients. There was no consistent pattern as related to the extent of MPI defects or exercise test results. CONCLUSION: Our study suggests that multiple perfusion abnormalities with different levels of severity are common in cardiac syndrome X, with more than 30 % of these patients having at least one abnormal perfusion segment. Our findings suggest that in these patients microvascular angina is probably more common than is generally believed.
