Prevalence of diabetes, obesity and hypertension in a Turkish population (Trabzon city).

OBJECTIVE: The objectives of this study were to determine the prevalence of diabetes mellitus in Trabzon city, Turkey, using standardized diagnostic criteria, and to evaluate associated factors. METHODS: A total of 3000 eligible study subjects were selected. Of those, 2646 subjects participated in the study. Individuals aged > or =20 years were selected from their family health cards and were invited to the health station. Anthropometric and demographic data were obtained for each subject. Plasma glucose was measured by an autoanalyser. People without previously diagnosed diabetes were categorized according to WHO diagnostic criteria as follows. Diabetes: a fasting plasma glucose (FPG)> or =140 mg/dl or 2-h plasma glucose > or =200 mg/dl after a 75-g oral glucose load. RESULTS: The overall prevalence of diabetes in those > or =20 years of age was 6.0% (n=160). Among diabetic subjects, 69 were newly diagnosed diabetes mellitus. Age, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP) and FPG were higher in diabetic subjects than in non-diabetic subjects. The prevalence of diabetes showed significant association with increased age (P<0.0001). The overall prevalence of obesity was 19.2%. The combined prevalence of both overweight and obesity was 60.6%. The prevalence of obesity was 27.4% among women and 10.7% among men (P<0.0001). Prevalence of diabetes increased with degree of obesity (P<0.0001). The rate of obesity in diabetic subjects was 35.6%. In the study population as a whole, the prevalence of obesity increased with age, being highest in the 50-59 years age group, but lower again in the 60+ age group. Prevalence of SBP> or =140 mmHg was 12.0% and of DBP> or =90 mmHg was 8.2%.

Effects of dopexamine on acute necrotising pancreatitis in rats.

OBJECTIVE: To examine the effects of dopexamine on pancreatic tissue oxygen tension (PtO2) and the extent of acinar injury in rats with acute necrotising pancreatitis DESIGN: Laboratory study. SETTING: Medical school, Turkey. ANIMALS: 68 Sprague Dawley rats. MAIN OUTCOME MEASURES: Cardiorespiratory measurements, pancreatic PtO2, effects on activity of serum amylase and concentration trypsinogen activation peptide (TAP). and histological picture. RESULTS: The four study groups (sham + saline, sham + dopexamine, acute pancreatitis and acute pancreatitis + dopexamine) were each divided into two; in 9 rats in each, pancreatic biochemistry was studied, and in the remaining 8 in each group serum biochemistry and histology were studied. The groups were comparable with regard to mean arterial pressure, heart rate, arterial blood gases, packed cell volume, and serum amylase activity. The use of dopexamine increased pancreatic PtO2 in the sham + dopexamine group without the important blood pressure changes. The induction of pancreatitis resulted in a significant reduction in pancreatic PtO2 in the pancreatitis groups. The use of dopexamine did not increase pancreatic PtO2. There were no significant differences in plasma TAP concentration and the extent of acinar cell injury in the animals in the pancreatitis groups. CONCLUSION: Treatment with dopexamine does not improve the pancreatic microcirculation or reduce the extent of acinar cell injury in acute necrotising pancreatitis and is therefore unlikely to be of benefit in patients with pancreatitis.

Effect of a somatostatin analogue (SMS 201-995) on tear secretion in rats.

PURPOSE: In this study we investigated the effect of a somatostatin analogue, octreotide, (SMS 201-995) on tear secretion in rats. METHOD: The animals were anaesthetized intraperitoneally (ip) with urethan (1.2 g/kg) The drugs were injected subcutaneously (sc.). Tear samples were collected by folding a 5 mm section of the Schirmer strip over the lower lid margin to absorb tear fluid from the lower conjunctival sac for 5 mm. Forty animals were divided into four groups (n = 10). Group I (control) received 1 ml of saline, group 2 received 100 microg/kg of SMS 201-995, group 3 received 50 microg/kg of acetylcholine (Ach), group 4 received 100 microg/kg of SMS 201-995 and 30 min later 50 microg/kg of Ach. At t = 0 the local anesthetic proparacain HCI was instilled onto the ocular surface to minimize reflex secretion. Baseline secretion was measured before administering the various treatments. RESULTS: While Ach alone significantly increased tear secretion, SMS 201-995 reduced it compared to saline (control) (p<0.0001, p<0.001, respectively). SMS 201-995 combined with Ach decreased tear secretion compared to Ach alone (p<0.03). CONCLUSION: SMS 201-995 significantly inhibits Ach stimulated tear secretion in rats.

Plasma endothelin-1 levels in Behçet's disease.

Plasma concentrations of endothelin-1 (ET-1), a vasoconstrictor peptide released from vascular endothelial and synovial cells, were measured by radioimmunoassay in 27 patients with Behçet's disease (BD) and 18 healthy controls. The plasma ET-1 concentrations were found to be significantly increased in patients with BD (121.15 +/- 11.6 fmol/dl) compared with the healthy subjects (89.37 +/- 8.03 fmol/dl p < 0.05). The elevation of ET-1 did not correlate with the disease duration, gender, ocular or articular involvement. Whether the elevated ET-1 level is a direct result of its increased synthesis from injured vascular endothelial cells or whether its presence in high concentrations may be responsible, together with other factors for both vascular and articular complications in patients with BD is uncertain.

Kinetic parameters of serum and lung tissue angiotensin-converting enzyme in patients with lung cancer.

Angiotensin-converting enzyme activity and its kinetic parameters were determined in both serum and lung tissue samples obtained from 17 patients with lung cancer and 21 control subjects, regardless of ethical base. The specific activities for cancerous and normal lung tissues were 67.2 +/- 27.3 (mean +/- SD) U/g protein and 28.5 +/- 5.4 U/g protein, respectively (P less than 0.001). Serum enzyme activity, on the other hand, was found to be higher in controls (198 +/- 42 U/L) than in patients (237 +/- 68 U/L) (P less than 0.01). The effects of chloride and zinc ions, pH and temperature on the enzyme activity were investigated as kinetic parameters in both serum and tissue samples.
