The effects of high intensity-interval training on vaspin, adiponectin and leptin levels in women with polycystic ovary syndrome.

AIM: We aimed to investigate the metabolic effects of HIIT exercise on PCOS patients and how it affects adiponectin, vaspin and leptin. MATERIAL AND METHODS: Twenty women with PCOS were included in the study and were divided into two groups. HIIT program was applied for 10 PCOS and Medium Intensity Continuous Training (MICT) program was applied for other 10 PCOS. At the beginning and at the end of the study, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), triglyceride(TG), insulin, Adiponectin, Leptin, Vaspin levels of both PCOS groups were evaluated. RESULTS: When PCOS patients by performed HIIT exercise for 12 weeks, we found that the levels of leptin and vaspin did not change while adiponectin levels increased. Moreover serum levels of insulin, TG, total cholesterol, LDL-C decreased but levels of HDL-C increased. CONCLUSION: HIIT increased in the adiponectin levels in women with PCOS and provided more weight loss.

VASPIN, ADIPONECTIN AND LEPTIN LEVELS IN TYPE 1 DIABETIC RATS INDUCED BY STREPTOZOTOCIN.

BACKGROUND: Adiponectin, vaspin and leptin are only a few of these numerous adipocytokines. Little is known about the behavior of adipocytokines and how adipose tissue metabolism is affected in this Type 1 DM model. In this study we investigated the serum levels of adiponectin, leptin, vaspin in streptozotocin(STZ) induced diabetic rats. MATERIAL AND METHODS: Twelve Spraque Dawley albino rats were included in the study. The animals were divided into two groups. The first group was diabetic (D) (n: 6) and 60mg / kg STZ was administered intraperitoneally (i.p.) to these rats. The second group was the non-diabetic control (ND) group (n: 6). All the animals were euthanized by cervical dislocation. Quantification of vaspin, Adiponectin, leptin in serum was performed using the ELISA kit. RESULTS: Adiponectin, vaspin levels of diabetic group were found to be statistically lower than of control group (p<0.05). Leptin levels were significantly higher in the diabetic group (P<0.05). CONCLUSION: There is a need for new researches that can explain the relationship between Vaspin, Leptin and Adiponectin and Type 1 diabetes. New studies in this area will open new horizons for the identification of new biomarkers in the diagnosis and treatment of Type 1 diabetes.

Association between C-reactive protein, neutrophil to lymphocyte ratio and the burden of apical periodontitis: a case-control study.

OBJECTIVE: Endodontic originated chronic apical periodontitis (AP) is an inflammatory disease of periapical tissue. High-sensitivity C-reactive protein (hsCRP) as an inflammatory marker and hemogram indexes provide valuable information to clinicians for diagnosis, screening and follow-up of various diseases. The aim of this study was to investigate AP in terms of its association with hemogram indices and hsCRP levels. MATERIAL AND METHODS: Study includes 104 patients with AP and 40 participants as the control group. 160 teeth were diagnosed as AP through digital radiographic images and scored with respect to Periapical Index (PAI) scoring. Afterwards, patients were categorized into 3 grades in accordance with both the number and the severity of AP. AP grade 0 was considered for the control group with regard to a new scoring system. Patients with only one tooth involved with AP with a PAI score of 3 or 4 were categorized as an AP Grade 1, when a patient had more than one tooth with a PAI score of 3 or 4 he was classified as an AP Grade 2 and a patient with at least one tooth scored as a PAI 5 was rated as an AP Grade 3. Hemograms and hsCRP levels were measured for each individual to establish a correlation with inflammatory markers. RESULTS: The neutrophil/lymphocyte ratio (NLR) levels of patients with AP Grade 3 were significantly higher than all other AP grades (p < .05). hsCRP levels in patients with an AP Grade 2 and 3 were higher than both AP Grade 0 and 1 (p < .05). CONCLUSIONS: hsCRP levels of patients were reliable predictive indicators for AP severity in correlation with the new proposed scoring system for AP.

Greater occipital nerve block in the treatment of triptan-overuse headache: A randomized comparative study.

OBJECTIVES: This study aims to investigate the efficiency of a single and repeated greater occipital nerve (GON) block using lidocaine in the treatment of triptan-overuse headache (TOH), whose importance has increased lately. MATERIALS AND METHODS: In the study, 105 consecutive subjects diagnosed with TOH were evaluated. The subjects were randomized into three groups. In Group 1 (n=35), only triptan was abruptly withdrawn. In Group 2 (n=35), triptan was abruptly withdrawn and single GON block was performed. In Group 3 (n=35), triptan was abruptly withdrawn and three-stage GON block was performed. All patients were injected bilaterally with a total amount of 5 cc 1% lidocaine in each stage. During follow-up, the number of headache days per month, the severity of pain (VAS), the number of triptans used, and hsCRP and IL-6 levels were recorded three times; in the pretreatment period, in the second month post-treatment, and in the fourth month post-treatment. They were then compared. RESULTS: There was a statistically significant difference in the post-treatment fourth month in comparison with the pretreatment period in Group 3 (P<.05). Compared to Group 1, the number of headache days, VAS, and decrease in triptan need in Group 3 was statistically significant compared to Group 2 (P<.05). Compared to pretreatment, in the fourth month post-treatment, both hsCRP and IL-6 levels were lower only in Group 3 (P<.05). CONCLUSIONS: We are of the opinion that repeated GON block in addition to the discontinuation of medication has significant efficacy for TOH cases.

Are cytokine levels in serum, endometrial tissue, and peritoneal fluid a promising predictor to diagnosis of endometriosis-adenomyosis?

AIM: The basic aim was to find a non-invasive procedure to diagnose and monitor endometriosis-adenomyosis. MATERIALS AND METHODS: A prospective study was carried out. The authors conducted a series of 60 consecutive patients who underwent diagnostic laparoscopy for benign gynecologic conditions. Endometrial, peripheral blood and peritoneal lavage samples were analyzed. IL-6, IL-16, TNF-alpha, and LIF levels were measured and compared. RESULTS: The authors analyzed clinical data of 52 patients (26 endometriosis, 13 adenomyosis, and 13 control group). Peritoneal fluid IL-6 is significantly higher in stage IV endometriosis group than the control group (p = 0.001). In the endometriosis group, the levels of TNF-alpha in the peritoneal fluid was higher than the control group (p = 0.008). In the endometriosis and adenomyosis groups, the levels of IL-16 in the peritoneal fluid were significantly higher than the control group (p = 0.000 and p = 0.002). CONCLUSIONS: Significant immune-inflammatory changes were observed. When the underlying molecular mechanisms will be investigated, this will elicit studies on the immunotherapeutic treatment of endometriosis. Further studies are needed to assess various potential therapeutic interests for biomarkers in a large, well-defined patient population.

Evaluation of early cardiac dysfunction in patients with systemic lupus erythematosus with or without anticardiolipin antibodies.

The aim of this study was to use transthoracic Doppler echocardiographic (TTE) imaging methods to identify cardiac dysfunction, an indicator of subclinical atherosclerosis in asymptomatic systemic lupus erythematosus (SLE) patients in terms of cardiac effects. This study involved 80 patients: a study group (n = 50) and control group (n = 30). They were categorized into four subgroups: anticardiolipin antibodies (aCL) (+) (n = 14) and aCL (-) (n = 36); systemic lupus erythematosus disease activity index (SLEDAI) ≥ 6 (n = 15) and SLEDAI < 6 (n = 35); disease period ≥ 5 years (n = 21) and disease period < 5 years (n = 29); major organ involvement (+) (n = 19), major organ involvement (-) (n = 31). The ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (E/E') for the study group was found to be higher than the control (p < 0.01). Systolic septal motion velocity (Ssm) was lower in the study group compared with the control (p < 0.01). Left atrium (LA) dimension was greater in the study group than the control (p < 0.01). Ssm was found to be lower in the aCL (+) patients compared with the control and aCL (-) groups (p < 0.01, p < 0.05, respectively). LA dimension was greater in the aCL (+) and (-) groups compared with the control, (p < 0.01, p < 0.05, respectively) and aCL groups compared with each other (p < 0.05). The E/E' ratio for the aCL (+) and (-) groups was found to be greater than the control (p < 0.05). In the study, both the Ssm and the late diastolic septal velocity (sA') was found to be lower in the SLEDAI ≥ 6 group compared with SLEDAI<6 group, (p < 0.001, p < 0.05, respectively). LA dimension was statistically greater in the SLEDAI ≥ 6 group compared with the SLEDAI <6 group (p < 0.001). E' and early diastolic septal velocity (sE') were statistically lower in the disease period >5 years group compared with the disease period <5 years group (p < 0.01, p < 0.05, respectively). Carrying out regular scans with TTE image of SLE patients is important in order to identify early cardiac involvement during monitoring and treatment. Identifying early cardiac involvement in SLE may lead to a reduction in mortality and morbidity rates.

Correlation of myocardial performance index assessed by different echocardiographic methods in patients with acute myocard infarction receiving different reperfusion treatment.

AIM: Myocardial performance index (MPI) is a well known prognostic parameter in acute myocardial infarction (AMI) patients, which has been used to assess global cardiac functions. In this study, we aimed to evaluate the corelation between the MPI levels obtained by PW doppler and Tissue doppler ultrasonography with reperfusion in AMI patients. METHODS: Fifty-four consecutive acute ST elevatation myocardial infarction patients, 26 treated with primary percutaneous coronary intervention (PCI) and 28 with thrombolytic therapy (TT); and 15 consecutive healthy controls were included in the study. MPI levels were measured with pulsed-wave (PW) doppler and tissue Doppler ultrasonography in all patients. The isovolumic relaxation time (IVRT), isovolumic contraction time (IVCT) and ejection time (ET) values used to measure MPI levels were determined. Corelation between the time intervals obtained with both methods were evaluated. MPI variations were evaluated in patients treated with PCI and TT. A significant corelation was observed in MPI levels obtained with PW doppler and tissue doppler ultrasonography (P<0.001) as well as between IRT, ICT and ET values (for all parameters; P<0.001). No significant corelation was observed between the MPI levels obtained with PW doppler and tissue doppler ultrasonography in patients treated with primary PTCA and TT (P=0.128, P=0.991, respectively). A significant corelation was observed between the MPI values obtained by PW doppler and tissue doppler ultrasonography with reperfusion interval (P=0.002, P<0.001, respectively). CONCLUSION: As a result, tissue Doppler ultrasonography may be used as an alternative to PW doppler to evaluate MPI, which is a well known prognostic factor in AMI. No relation has been observed between MPI values in early phases of AMI with reperfusion pattern, while a connection has been observed between MPI and reperfusion interval.

A retrospective study of angiographic ally determined anomalous coronary arteries in 12,844 subjects in Thrace region of Turkey.

BACKGROUND: Congenital anomalies of the coronary arteries are rarely encountered in patients undergoing cardiac catheterization. In patients undergoing coronary angioplasty or cardiac surgery, angiographic recognition of coronary anomalies is important for the proper management of these patients. METHOD: We retrospectively reviewed the records of 12,844 patients who had previously undergone coronary angiography in the catheterization laboratory of Trakya University Cardiology Department over the past 14 years. We tried to investigate the presence of a variety of coronary anomalies in these patients to determine the prevalence of various types of anomalies and their anatomic variation in a selected population of the European part of Turkey. The potential association between coronary atherosclerosis and congenital coronary anomalies was also investigated. RESULTS: Among these patients, 95 patients were found to have major coronary anomalies that predominantly comprised anomalous aortic origin of coronary arteries. Among the major anomalies, anomalous aortic origin of the left circumflex (LCX) artery from the right sinus of Valsalva or right coronary artery (RCA) was found to be the the most prevalent (46 out of 95 patients) outnumbering the second most common anomaly that was anomalous aortic origin of the RCA (32 out of 95 patients). In the present study, the incidence of major coronary arterial anomaly was found to be 0.74 %. However, only about one third of the patients (31 out of 95, 32.6%) with major anomaly had significant coronary atherosclerotic lesions among whom nine were found to involve the LCX artery with a posterior course. CONCLUSION: The incidence of congenital coronary anomalies in a selected population of the European part of Turkey is similar to those of other populations. Congenital coronary anomalies generally present as isolated anomalies and are not associated with an increased risk of coronary atherosclerosis in this series. Cardiologists and surgeons should be familiar with these entities for the proper management of patients undergoing cardiac surgery or coronary angioplasty.

Continuous nisin production with bioengineered Lactococcus lactis strains.

Nisin production in continuous cultures of bioengineered Lactococcus lactis strains that incorporate additional immunity and regulation genes was studied. Highest nisin activities were observed at 0.2 h(-1) dilution rate and 12.5 g l(-1) fructose concentration for all strains. Recombinant strains were able to produce greater amounts of nisin at dilution rates below 0.3 h(-1) compared to the control strain. However, this significant difference disappeared at dilution rates of 0.4 and 0.5 h(-1). For the strains LL27, LAC338, LAC339, and LAC340, optimum conditions for nisin production were determined to be at 0.29, 0.26, 0.27, and 0.27 h(-1) dilution rates and 11.95, 12.01, 11.63, and 12.50 g l(-1) fructose concentrations, respectively. The highest nisin productivity, 496 IU ml(-1) h(-1), was achieved with LAC339. The results of this study suggest that low dilution rates stabilize the high specific nisin productivity of the bioengineered strains in continuous fermentation. Moreover, response surface methodology analysis showed that regulation genes yielded high nisin productivity at wide ranges of dilution rates and fructose concentrations.

A practical approach to glomerular filtration rate measurements: creatinine clearance estimation using cimetidine.

Determination of creatinine clearance (Ccr) is not a reliable indicator of glomerular filtration rate (GFR), owing to tubular secretion of creatinine. It has been reported that Ccr measurements can approximate true GFR after cimetidine (Ci) administration. In this study, GFR was estimated by Cockcroft and Gault's equation (C(C-G)) based on measurement of plasma creatinine, and Ccr was determined by the standard clearance equation using 4- and 24-hr urine samples (Ccr4 and Ccr24, respectively) in 17 patients and 10 healthy controls. After cimetidine administration (800 mg, 3 times daily), GFR values were recalculated at the same time periods (C(CiC-G), CcrCi4 and CcrCi24, respectively). The results were all compared to those obtained by the 99mTc-DTPA protein-free double-sample method (C(DTPA)), which is a reference method for GFR determination. The coefficient of variation (CV%) for Ccr24/C(DTPA) was high before cimetidine administration; Ccr24 and CcrCi24 values were significantly different from C(DTPA) (CV 23.1%, Ccr24/C(DTPA) = 1.17, p 0.005; and CV 14.1%, CcrCi24/C(DTPA) = 0.92, p 0.006, respectively). Ccr4 values obtained before cimetidine ingestion showed large variation and were significantly different from C(DTPA) (CV 15.5%, Ccr4/C(DTPA) = 1.11, p 0.001). CcrCi4 values after cimetidine were similar to CDTPA (CV 6.9%, CcrCi4/C(DTPA) = 1.01, p 0.28). C(C-G) estimates were higher before cimetidine intake (CV 12.4%, C(C-G)/C(DTPA) = 1.21, p <0.001), whereas C(CiC-G) values were not significantly different from C(DTPA) values (CV 7.0%, C(CiC-G)/C(DTPA) = 1.01, p 0.67). This study shows that GFR estimations by C(C-G), Ccr4, Ccr24, or CcrCi24 are insufficiently reliable. On the other hand, C(CiC-G) and CcrCi4 results are acceptable for true GFR estimations.

Serum total and lipid-bound sialic acid levels following acute myocardial infarction.

Although serum total sialic acid has been shown to be a cardiovascular risk factor, with elevated levels associated with increased cardiovascular mortality and also with cerebrovascular disease, the reason for the elevation in serum sialic acid content remains obscure. It has been shown that an increased output of serum proteins by the liver due to some type of acute phase reaction may be one of the possible sources of an increased serum sialic acid concentration in patients with myocardial infarction. An increase in the activity of sialidase, which cleaves the terminal sialic acid residues from oligosaccharides, glycoproteins and gangliosides, may also play an important role in the elevation of serum total sialic acid in myocardial infarction. Elevated serum total sialic acid in the blood might result either from the shedding or secreting of sialic acid from the cell membrane surface, or releasing of cellular sialic acid from the cell into the bloodstream due to cell damage after myocardial infarction. The purpose of the present study is to investigate serum total and lipid-bound sialic acid and the enzymes serum lactate dehydrogenase, creatine kinase and aspartate aminotransferase in patients with acute myocardial infarction, at 24 h post-infarction (day 1), 48 h post-infarction (day 2) and 72 h post-infarction (day 3). A possible role of cell damage in the elevation of serum total and lipid-bound sialic acid levels in these patients was also evaluated. In this study, 40 patients with myocardial infarction ranging in age from 42 to 68 years, and 26 healthy volunteers ranging in age from 45 to 71 years were included. Serum total sialic acid determination was carried out by the thiobarbituric acid method of Warren and lipid-bound sialic acfd by the method of Katopodis. Our data shows that a) there is a gradual increase in the levels of serum total sialic acid and lipid-bound sialic acid during the first three days after the acute myocardial infarction and b) the elevation in serum total sialic acid levels correlates with the elevation in lactate dehydrogenase activity only on day 1 following infarction. Therefore, either the shedding or secreting of sialic acid from the cell or cell membrane surface may be partly responsible for an increased serum sialic acid concentration especially on day 1 following myocardial infarction.

The effect of pneumoperitoneum on bacterial clearance and RES functions in a model of E. coli peritonitis.

The use of laparoscopic surgery in peritonitis has increased rapidly. The present study examined the effects of pneumoperitoneum on bacterial clearance. Spraque-Dawley rats were divided into six groups of seven animals. In groups 1 and 4, laparotomy with a midline incision was performed and 10(9) E. coli in a volume of 1 ml inserted into the peritoneal cavity. Groups 2, 3, 5, 6 received an identical quantity of E. coli by intraperitoneal injection. Groups 3 and 6 received carbon dioxide pneumoperitoneum at a constant pressure of 5 mmHg for 60 minutes after intraperitoneal injection of E. coli. In one hour groups; the mean bacterial counts per lung from the E. coli injection with laparotomy group was significantly higher than for the E. coli injection with pneumoperitoneum group (p < 0.05). The mean bacterial counts per kidney in the E. coli injection with laparotomy group was higher compared with the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.0001). There was statistically significant difference in quantitative bacteraemia between the E. coli injection with laparotomy group and the E. coli injection or E. coli injection with pneumoperitoneum groups (p < 0.05). In four-hour groups; the mean bacterial counts of lungs and liver-spleen were significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05 and p < 0.001 respectively). The quantitative bacteria was significantly higher in the E. coli injection with laparotomy group than in the E. coli injection and E. coli injection with pneumoperitoneum groups (p < 0.05). This study demonstrates that pneumoperitoneum impairs the clearance of bacteria from the peritoneal cavity in an experimental model of peritonitis. However, we could not detect the deleterious effects of pneumoperitoneum compared with laparotomy.

Heart failure during first inferior acute myocardial infarction.

BACKGROUND: Inferior acute myocardial infarctions (AMI) have better in-hospital prognosis than do anterior AMI. Authors of several studies reported that patients with inferior AMI complicated by atrioventricular block, concomitant precordial ST-segment depression and involvement of right ventricle have larger infarctions and a worse prognoses than do patients without these features. OBJECTIVE: To analyse the incidence, clinical course and in-hospital prognosis of patients with heart failure and first inferior AMI. METHODS: We analysed in 257 consecutive patients with first inferior AMI who had been admitted to the coronary care unit during January 1991 and March 1995. The clinical and electrocardiographic characteristics, as well as the morbidities and in-hospital mortalities, of groups of patients with and without heart failure during inferior AMI were compared. RESULTS: Symptoms and signs of heart failure were noted for 49 patients (19%). We found that patients who had suffered heart failure during inferior AMI were older (62.1 +/- 9.86 versus 58.78 +/- 10.58 years, P < 0.05) than those who had not suffered heart failure. There was no significant difference between patients' sex, history of diabetes mellitus, hypertension, smoking status, thrombolytic therapy, involvement of right ventricle and QRS score for these two groups. We found a greater prevalence of ST-segment depression (ST-segment depression > or = 1 mV in more than one precordial lead with maximal ST-segment depression in leads V4-V6) of V4-V6 precordial leads (57 versus 26%, P = 0.00002) and a lesser prevalence of no ST-segment depression (ST-segment depression < 0.1 mV in each precordial lead; 14 versus 38%, P = 0.001) among patients who had suffered heart failure. We found greater incidences of serious ventricular arrhythmias (53 versus 26, P = 0.0002) and ventricular tachycardiafibrillation (16 versus 7%, P = 0.03) among patients who had suffered heart failure than we did among those who had not. Third-degree atrioventricular block was more often found in patients who had suffered heart failure (23 versus 12%, P = 0.07) but this difference was not statistically significant. We found that the in-hospital mortality among patients who had suffered heart failure was much higher than that among those who had not (24.5 versus 3.8%, P = 0.000001). CONCLUSION: We found that heart failure occurs primarily in old patients, and in those with precordial ST-segment depression, especially in leads V4-V6. The patients who suffer heart failure have worse in-hospital prognosis due to serious ventricular arrhythmias and cardiogenic shock.

Antianginal and anti-ischemic effects of nisoldipine and ramipril in patients with syndrome X.

BACKGROUND: Syndrome X is defined as typical angina pectoris, positive treadmill exercise test, negative intravenous ergonovine test, and angiographically normal coronary arteries. HYPOTHESIS: In the present study, we investigated the anti-ischemic and antianginal effects of nisoldipine and ramipril in patients with syndrome X. METHODS: After 2 weeks of the first wash-out period, 18 patients (7 men, 11 women, age 46 +/- 10 years) were given nisoldipine (NIS) 5 mg twice daily for 4 weeks, and after 2 weeks of the second wash-out period, the same patients were given ramipril (RAM) 2.5 mg once daily for 4 weeks. A treadmill exercise test with modified Bruce protocol was performed at the end of each period. RESULTS: The time to angina in exercise (607 +/- 115 s-650 +/- 117 s, p = 0.006, vs. 630 +/- 114 s-660 +/- 123 s, p = 0.02), total exercise time (612 +/- 110 s-656 +/- 114 s, p = 0.0008, vs. 630 +/- 114 s-660 +/- 123 s, p = 0.02), and maximum MET value (11.09 +/- 2.08-11.86 +/- 2.04, p = 0.0016, vs. 11.42 +/- 2.09-12.2 +/- 2.26, p = 0.01) were increased significantly with both therapy modalities. The time to 1 mm ST-segment depression (123 +/- 93 s-220 +/- 172 s, p = 0.002) was increased significantly with NIS therapy. The time to ST-segment recovery (434 +/- 268 s-330 +/- 233 s, p = 0.016 vs. 443 +/- 289 s-370 +/- 278 s, p = 0.012), the frequency of anginal attacks per week (1.27 +/- 1.4-0 +/- 0.38, p = 0.005, vs. 1 +/- 1.32-0.33 +/- 0.59, p = 0.028), and the need for sublingual nitroglycerin (1.16 +/- 1.29-0.11 +/- 0.32, p = 0.005, vs. 0.94 +/- 1.16-0.27 +/- 0.57, p = 0.012) were decreased significantly with both drugs. CONCLUSION: We observed that 10 mg daily NIS and 2.5 mg daily RAM have similar anti-ischemic and antianginal effects in patients with syndrome X.

Effect of parsley (Petroselinum crispum) on the skin of STZ induced diabetic rats.

Parsley (Petroselinum crispum) is one of the medicinal herbs used by diabetics in Turkey and it has been reported to reduce blood glucose. The purpose of this study therefore was to investigate the effect of feeding parsley on diabetes induced impairments in rat skins. Uncontrolled induced diabetes caused significant increases in nonenzymatic glycosylation of skin proteins, lipid peroxidation and blood glucose. Administration of parsley extract did not inhibit these effects except for the increase in blood glucose. SDS-polyacrylamide gel electrophoresis revealed no significant differences in any protein bands between any of the groups.

Rupture of the hydatid disease of the liver into the biliary tracts.

BACKGROUND: To analyze the diagnosis and the surgical treatment of intrabiliary ruptured hydatid disease of the liver. METHODS: Between 1990 and 1995, 263 patients with hydatid cysts of the liver underwent surgery in a university hospital. Twenty-five (9.43%) patients with intrabiliary rupture of hepatic hydatid cyst were retrospectively reviewed. RESULTS: Diagnosis was principally made using ultrasonography and computed tomography scanning and was confirmed by the findings of other tests. In 12 patients (48%) partial cystectomy with primary closure; 5 patients (20%) partial cystectomy with drainage; 5 patients (20%) cystotomy with drainage; 3 patients (12%) left hepatic resection (atypic, segmentary or lobar) was performed. Omentoplasty was performed in 6 patients. The common bile duct was explored in all patients and it was drained by a T-tube in 22 patients, and by a choledochoduodenostomy in 3 others. The average postoperative hospitalization time was 8.3 and 22.5 days in patients treated with choledochoduodenostomy and T-tube drainage respectively. Cholecystectomy was performed in 18 patients. Complications were seen in 4 patients (16%) with 1 pleural effusion and 3 wound infections. There was only 1 death (4%) due to duodenal peptic ulcus perforation with intrabiliary ruptured hydatid cyst. CONCLUSION: This study indicates that T-tube drainage and choledochoduodenostomy in intrabiliary ruptured hydatid cysts are effective procedures with low morbidity and mortality rates.

The effect of chard (Beta vulgaris L. var. cicla) on the skin of streptozotocin induced diabetic rats.

Chard (Beta vulgaris L. var. cicla) is one of the plants used as hypoglycaemic agent by diabetics in Turkey and it has been reported to reduce blood glucose. The purpose of this study was to investigate the effect of feeding chard on diabetes induced impairments in rat skins. Uncontrolled induced diabetes caused significant increases in nonenzymatic glycosylation of skin proteins, lipid peroxidation and blood glucose. Administration of chard extract inhibited these effects except the increase in lipid peroxidation. SDS-polyacrylamide gel electrophoresis revealed no significant differences in any protein bands between any of the groups. The data indicate that the use of chard may be effective in preventing or at least retarding the development of some diabetic complications.

Early and late advanced atrioventricular block in acute inferior myocardial infarction.

BACKGROUND: Advanced atrioventricular block is a frequent complication in patients with inferior acute myocardial infarction (AMI); in patients in hospital, it often occurs concurrently with other complications and is associated with high mortality. Very little information is available about early and late advanced atrioventricular block in inferior AMI. We hypothesized that the time of appearance of advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy may affect the prognosis of patients with inferior AMI. METHODS: We studied 51 patients with inferior AMI and advanced atrioventricular block characterized by poor response to atropine requiring temporary pacemaker therapy. According to pre-established electrocardiographic criteria and the time of appearance of the advanced atrioventricular block, patients were divided into two groups: an early block group consisting of 30 patients who developed advanced atrioventricular block during the first 24 h of inferior AMI, and a late block group consisting of 21 patients who developed advanced atrioventricular block after the first 24 h of chest pain. RESULTS: The groups were similar regarding age, coronary risk factors, frequency of right ventricular infarction, QRS score, atrial and ventricular rates, the time of return to first-degree atrioventricular block, cardiac arrhythmias, heart failure and mortality. The early advanced atrioventricular block group included a greater number of men than did the late group (P = 0.017). CONCLUSION: These data suggest that the time of appearance of advanced atrioventricular block does not affect the prognosis of hospital patients with inferior AMI.

Effect of vitamin B6 on lenses of diabetic rats.

Vitamin B6 is essential for the metabolism of fat, carbohydrate and protein. In this study the effect of vitamin B6 on diabetes induced impairments in rat lenses was investigated. Although macroscopic examination revealed no opacification of rat lenses in any groups, uncontrolled induced diabetes caused significant decreases in lens glutathione and increases in lens protein nonenzymatic glycosylation and blood glucose. Administration of vitamin B6 did not inhibit these diabetes induced alterations significantly. SDS-polyacrylamide gel electrophoresis revealed some significant differences in some protein bands between groups.
