Abstract
Bu çalışmada adjuvan kullanılarak tek doz Subkutan (SC) FSH uygulamasının ve adjuvan kullanılmadan tek doz epidural FSH uygulamasının kan FSH düzeyleri ve süperovülasyon yanıtı üzerine etkilerinin belirlenmesi amaçlanmıştır. Holştayn inekler (n:18) süperovülasyon prosedürü için üç gruba ayrıldı (n = 6). Gruptaki (İM) hayvanlara 4 gün süreyle 12 saat arayla İntramusculer (IM) azaltıcı FSH (Stimufol, 500 μg domuz FSH ve 100 μg domuz LH, Ulg FMV, Liège, Belçika) dozları verildi. (E) grubundaki hayvanlara epidural aralığa FSH (500 µg) verildi. (SC) grubundaki hayvanlara, 10 mL Montanide ISA 206 adjuvanı içinde FSH eklenerek hazırlanan bir karışım Subkutan (SC) ile uygulandı. Overdeki CL sayısı ultrasonografik yöntemle ölçüldü ve 4 CL varlığına göre süperovülasyon belirlendi. FSH ölçümü için tüm hayvanlardan V. jugularis'ten kan örnekleri alındı. Serum FSH (pFSH) seviyeleri ELISA ile belirlendi. Grup 1'deki tüm hayvanlar, süperovülasyon prosedüründen sonra süperovülasyon tepkisine (4>CL) sahipti. 2. grupta sadece bir hayvan yanıt verdi. Grup 3'te, altı hayvandan dördü yanıt verdi. Kan örneklerinin FSH analizinden sonra, IM ve SC uygulamaları arasındaki fark istatistiksel olarak önemsiz iken, IM ve epidural uygulamalar arasındaki fark istatistiksel olarak anlamlıydı. SC ve epidural uygulamalar arasındaki fark önemsizdi.

Abstract
Thermal martensite characteristics in Fe-29%Ni-2%Mn-2%Co alloy were investigated with scanning electron microscopy (SEM) and Mössbauer spectroscopy characterization techniques. SEM observations obviously revealed the lath martensite morphology in the prior austenite phase of examined alloy. As well, the martensitic transformation kinetics was found to be as athermal type. On the other hand, Mössbauer spectroscopy offered the paramagnetic austenite phase and ferromagnetic martensite phase with their volume fractions. Also, the internal magnetic field of the martensite was measured as 32.9T from the Mössbauer spectrometer.

Abstract
Peritoneal tuberculosis (TB) is similar to ovarian cancers with respect to clinical, radiological laboratory findings. In this report, we present 10 TB cases with malignity pre-diagnosis based on the presence of ascites, pelvic mass, abdominal lymph nodes and elevated Ca125. The mean age of the cases was 29 +/- 14.4 years (18-63). Eight cases were associated with ascites, and the mean adenosine deaminase (ADA) value in ascitic fluid was 130.37 +/- 92.2. All cases had elevated levels of serum Ca125. In 6 cases, we identified lung pathologies based on chest radiography. Diagnoses were made based on diagnostic laparotomy in four cases, laparoscopy in two cases, percutaneous needle biopsy in two cases, and clinical evaluation in two cases. Anti-TB treatments lasted 12 months. Serum Ca125 levels normalised in the 3rd month of treatment. In the differential diagnosis of ascites and high serum Ca125 levels, tuberculosis should be considered in patients from developing countries.

Abstract
Sputum smear and culture conversion are important indicators for the effectiveness of treatment and the infectivity of the patient. The aim of this study was to identify the factors influencing both sputum smear and culture conversion time among patients with new case pulmonary tuberculosis (TB). The study was conducted in a reference hospital in Turkey in which 737 patients with pulmonary TB were hospitalised between January 2000 and 2005. We evaluated 306 (193 men and 113 women) human immunodeficiency virus-negative patients diagnosed with new case pulmonary TB. Factors associated with both sputum smear and culture conversion time (days) were investigated. Patients with diabetes mellitus (DM), cavitary disease, radiologically extensive disease had longer sputum smear and culture conversion time than the other groups. In addition, old age, male sex, smoking and thrombocytosis were found to be significantly associated with sputum smear conversion time. In the logistic regression analysis, the presence of DM and extensive disease were determined as independent factors associated with persistent sputum smear and culture positivity at the end of 2 months. The presence of DM and extensive disease were found to be independent risk factors influencing both sputum smear and culture conversion time in pulmonary TB. Sputum smear and culture examinations should be considered together to assess the poor prognosis.

Abstract
A neural network model that can learn higher order correlations within the input data without suffering from the combinatorial explosion problem is introduced. The number of parameters scales as M x N, where M is the number such that no higher order network with less than M higher order terms can implement the same input data set and N is the dimensionality of the input vectors. In order to have better generalization, the model was designed to realize a supervised learning such that after learning, output for any input vector is the same as the output of a higher order network that implements the same input data set using M number of higher order terms. Unlike the case in product units, the local minima problem does not pose itself as a severe problem in the model. Simulation results for some problems are presented and the results are compared with the results of a multilayer feedforward network. It is observed that the model can generalize better than the multilayer feedforward network.

Abstract
BACKGROUND Brucella endocarditis (BE) is a lethal complication of human brucellosis, which is rarely seen and hardly described. METHODS In the present report, six successfully treated cases of BE involving three native aortic valves, two native mitral-aortic valves, and a mitral bioprosthesis are described. The diagnosis of BE was based on clinical features, high brucella serologic titers, and positive blood cultures. Although the blood cultures were positive in all patients, all the resected valve materials and tissue cultures were negative. The patients received rifampicin, streptomycin, and doxycycline (in 3 patients), rifampicin, tetracycline, and cotrimoxazole (in 2 patients), and rifampicin, doxycycline, and cotrimoxazole (in 1 patient). Infected native valves and bioprosthesis were replaced by mechanical valves. RESULTS There was no early or late mortality. No recurrent infection developed after management with a combination of antibiotherapy lasting 6 months postoperatively during a mean follow-up of 47 months (range 20 to 84 months). CONCLUSIONS This report suggests that the combination of valve replacement and antibiotic therapy produces successful results in the treatment of BE.

Abstract
BACKGROUND Bioprosthetic valve use represents a crucial improvement in surgical treatment of mitral valve disease. The aim of this study is to determine the long-term durability of the Biocor porcine bioprosthetic mitral valve. METHODS Between 1985 and 1989, a total of 158 Biocor porcine bioprosthetic valves were placed in the mitral position, and long-term results of these patients were investigated retrospectively in 1999. RESULTS Thirty-day mortality was 4.4% (7 patients). Total follow-up was 1,499 patient-years. Actuarial survival was 83.66% +/- 3% at 5 years, 77.78% +/- 3.36% at 13 years (1.8% patient-year). Multivariate analysis demonstrated younger age, duration of implantation, congestive heart failure, and functional class to be significant predictors of late mortality. Actuarial freedom from valve-related mortality was 98.58% +/- 1% at 15 years (0.13% patient-year). Actuarial freedom from structural valve deterioration was 95.49% +/- 1.8% at 5 years, 70.2% +/- 4.12% at 10 years, and 64.82% +/- 5.34% at 13 years (2.6% patient-year). Actuarial freedom from structural valve deterioration-related reoperation was 98.43% +/- 1.1% at 5 years, 89.15% +/- 2.85% at 10 years, and 76.82% +/- 7.91% at 14 years. Multivariate analysis showed younger age and duration of implantation to be significant predictors of structural valve deterioration and its related reoperation. CONCLUSIONS By studying a 15-year time period, it is seen that this new generation porcine bioprosthetic valve should be considered an alternative for mechanical valves in selected patients.

Abstract
BACKGROUND Pulmonary dysfunction is still a major problem in coronary artery bypass grafting (CABG). The purpose of this randomized study was to determine the effect of different CABG techniques on pulmonary function. METHODS Fifty eight patients with severe obstructive pulmonary disease had elective isolated coronary surgery. The surgical methods for the patients with chronic obstructive pulmonary disease (COPD) were standard CABG in 18 patients (group 1), beating heart surgery in 19 patients (group 2), and minimally invasive direct coronary artery bypass grafting (MIDCABG) in 21 patients (group 3). RESULTS The earliest extubation time was from group 3 (p < 0.001). The average stay in the intensive care unit was significantly longer in group 1 (2.6 +/- 1.5 days) than in groups 2 (1.4 +/- 0.8 days) and 3 (1.1 +/- 0.8 days) (p < 0.05). The most prevalent respiratory morbidity was atelectasis that developed in 6 patients from group 1, in 2 patients from group 2, and in 3 patients from group 3. Forced expiratory volumes in 1 second (FEV1) obtained in the second postoperative month were significantly lower than preoperative values only in group 1 (p < 0.05). Forced vital capacity (FVC) values were significantly lower than the preoperative values in all three groups (p < 0.05). CONCLUSIONS Off-pump bypass surgical procedures are more advantageous than on-pump methods for patients with COPD. These patients can be operated on using the beating heart technique or by using MIDCABG to prevent side effects of CPB on pulmonary function and effects of sternotomy.

Abstract
BACKGROUND Coronary bypass surgery that provides good long-term graft patency can be performed on the beating heart as a viable alternative to conventional coronary artery bypass grafting (CABG). METHODS From September 1993 to December 1996, 696 patients underwent CABG on the beating heart at the Koşuyolu Heart and Research Hospital in Istanbul. Among them, 70 patients were chosen randomly for angiographic assessment of off-pump coronary artery bypass grafting. RESULTS The interval from operation to angiography varied from 24 to 61 months (mean, 36.1+/-10.9 months). The patency rate of left internal mammary-left anterior descending artery anastomoses was 95.59% (patency achieved in 65 of 68 patients) and of vein grafts was 47.06% (patency achieved in 16 of 34 patients) (p < 0.0001). The patency rates of grafts anastomosed to the left anterior descending artery were significantly higher than the rates of the grafts anastomosed to the other coronary arteries (95.71% versus 45.45%, p < 0.0001). Multivariate analysis showed that graft type (p < 0.0001) and hyperlipidemia (p = 0.023) were significant predictors for graft occlusion. Left ventricular function improved significantly after CABG (p = 0.04). Reintervention (using percutaneous transluminal cardiac angioplasty) and reoperation rates were 0.97% and 1.4%, respectively. CONCLUSIONS Off-pump coronary artery bypass grafting appears to produce midterm and long-term patency rates that are comparable to those of conventional techniques; that is especially true in cases of arterial conduits and of conduits anastomosed to the left anterior descending artery.

Abstract
Landmine explosions bring a formidable challenge to both patients and reconstructive surgeons. Free tissue transfer is the only method of repairing such extensive soft tissue defects of the foot after serial debridements. Sixty-five consecutive free muscle flap transfers were performed in 54 patients who had foot defects involving soft tissue and bone due to mine explosions. Although posttraumatic vessel disease had complicated most of the cases, overall flap survival rate was 83%. Each patient was ambulatory. Ulceration in long-term period was seen in only one patient. Eighty-five percent of patients with successful bone reconstruction and 41.6% of patients without adequate bone replacement demonstrated normal weightbearing in footprints and gait analysis. Free muscle flaps with split thickness skin graft and bone replacement are recommended for the reconstruction of such devastating wounds.

Abstract
BACKGROUND AND AIM OF THE STUDY Rupture of congenital sinus of Valsalva aneurysm is a rare cardiac malformation that usually causes reduced cardiac performance. METHODS Twenty patients (mean age 28.3 +/- 10.7 years; range: 14 to 55 years) with rupture of congenital sinus of Valsalva aneurysm were operated on at our institution between January 1985 and March 1999. The origin of the ruptured aneurysms was the right coronary sinus in 18 patients (90%) and the non-coronary sinus in two (10%). No ruptures were observed originating from the left coronary sinus. The aneurysms ruptured into the right ventricle in 14 patients (70%), into the right atrium in five (25%), and into the left ventricle in one patient (5%). Subarterial ventricular septal defect (VSD) was the most common associated defect (30%), and aortic insufficiency the second (20%). No correlation was found between subarterial VSDs and aortic insufficiency (p > 0.05). To achieve repair, the aorta and cavity into which the aneurysm had ruptured were opened. The aneurysmal sac was excised and the defect closed with a patch in 18 patients, and without patch in two. RESULTS One patient died in hospital (mortality rate 5%); no late mortality was observed. Surviving patients were followed up for 4.4 +/- 3.3 years (range: 1 to 13 years). The actuarial survival rate was 95% at 12.35 years. Recurrence of fistula was observed in one patient (5%) in whom the ruptured aneurysm had been closed by primary suture without the use of a patch. At 12.35 years, the actuarial freedom from recurrence of fistula was 94.74% for all survivors, and 100% for patients with patch closure. No late complications have been observed. CONCLUSIONS Following diagnosis of ruptured sinus of Valsalva aneurysm, surgical repair is the treatment of choice. Surgery performed as rapidly as possible after diagnosis in general leads to an excellent outcome.

Abstract
OBJECTIVE Recently, closed mitral commissurotomy (CMC) has been reexplored due to the concepts of less invasive valvular surgery. The feasibility of closed mitral commissurotomy via port access or limited thoracotomy by aid transesophageal echocardiography (TEE) was investigated in this clinical study. METHODS Between August 1996 and April 1998, 42 patients (32 women, ten men with a mean age of 36.2+/-7.8 years) underwent less invasive CMC at the Kosuyolu Heart and Research Hospital. CMC procedure were done through a limited (12-16 cm) thoracotomy incision in 23 patients, a very limited or mini thoracotomy incision (7-8 cm) in 11 patients and port access by aid TEE in eight patients. Preoperative mean mitral valve area was calculated as 1.19+/-0.13 cm2 and mean mitral valve gradient was measured as 14.8+/-3.2 mmHg. TEE provided information about the mitral valve anatomy and functions during the procedure in all patients. RESULTS Commissurotomy was successfully performed in all patients. In eight patients, a Tubbs dilator was inserted via port access at the 6th intercostal space from a 3-cm incision. Incision by guidance of TEE and CMC could be performed without thoracotomy in five patients. In three patients of the port access group, a very limited thoracotomy was required to perform CMC by digital guidance. Postoperative mean MVA was 2.37+/-0.29 cm2, minimal mitral gradient was 5.3+/-1.7 mmHg. In eleven patients, minimal mitral regurgitation was observed. The operations and postoperative period were free of complications in all patients. Following an average 12+/-2.8 h intensive care unit period, all patients were discharged after an average of 3.4+/-0.8 days of hospitalization. CONCLUSION Limited thoracotomy has less detrimental structural effects in patients. Port access by aid TEE approach to CMC may offer less invasiveness, lower cost effectiveness and be an alternative to percutaneous balloon mitral valvotomy.

Abstract
Hypercoagulability 2-3 h following scald injury and vessel thrombosis are well-known complications of burn injury. The present study was designed to determine the effect of recombinant tissue-type plasminogen activator (r-tPA) on vessels thrombosis in zones of stasis postburn. Twenty rats were assigned to experimental and control groups (N:10). After shaving the backs, a 'comb burn' was given bilaterally on the back of the rats 0.5 cm lateral and parallel to the midline by using a brass probe consisting of four rows (10 x 20 mm) and three interspaces (5 x 20 mm). Standardized full-thickness burns of the experimental group were treated with r-tPA via femoral veins 2 h after the burn, while the control group rats were infused the same volume of saline. Interspaces between the rows and vertical space area were evaluated as zone of stasis. The skin blood flow measurements of interspaces revealed a decreased level immediately and 2 h after the burn injury, averaging 11.3 and 9.8 perfusion units, respectively. On day 7, blood flow measurements of interspace and vertical space areas significantly differed between the groups, averaging 11.9 PU in the experimental and 1.8 PU in the control groups (P<0.05). To evaluate perfusion, each rat received 3 mCi of technetium-99m methoxyisobutylisonitrile on the first or seventh day postburn. After 30 min, the entire back skins including the panniculus carnosus muscle layer were dissected away. Gamma camera images revealed that in the experimental group the interspace areas took up 60-90 per cent more radioactivity than the burned areas while in the control group 20-50 per cent more activity was taken up by the interspace area when compared to burned areas. Autoradiography gave the exact borders of the necrotic and survived tissues. The percentage of live interspace and vertical space areas in the experimental group was 87.8 per cent on day 7, while it was 31.8 per cent in the control group (P<0.05). Dry/wet ratios did not reveal any significant difference at 24 h postburn. These results confirm that treatment with this selective fibrinolytic agent (r-tPA) after burn injury would have some benefits on saving the zone of stasis in burns.

Abstract
The case of a patient who injected 10 cc of metallic mercury subcutaneously into his left forearm through multiple punctures in an attempt at suicide is presented. Diagnosis was made by plain radiography of his left forearm, which exhibited redness, edema, and tenderness on the third day postinjection. Early excision of all affected subcutaneous tissues including metallic mercury deposits was performed on the fifth day postinjection. Blood and urine mercury levels that were initially found in high levels decreased dramatically to normal ranges after the excision and remained unchanged at the follow-up period of 6 months. No renal or hepatic functional impairment was encountered. The patient was free of toxic symptoms and mercury embolism. The local, aseptic lytic property of metallic mercury, which could cause severe damage to vital structures, was observed perioperatively. Early diagnosis and early, massive excision of mercury deposits in affected tissues is the important treatment modality in these rare cases.

Abstract
This prospective study was undertaken to evaluate limbal conjunctival autotransplantation in the management of cases with recurrent pterygium. At present, new surgical techniques to prevent pterygium recurrence following surgery are in investigation. In recent years, it has been postulated that pterygium is due to hypofunction of limbal stem cells. Thirty-one out of 49 patients with recurrent pterygium were treated by limbal-conjunctival autograft transplantation and the other 18 treated by Czermak technique, including two line of limbal cauterization intraoperatively, and used as a control group. During a mean follow-up period of 10 months (ranging 3-18 months), 4 recurrences (13.3%) in the limbal-conjunctival autograft transplantation group and 9 recurrences (50%) in the control group were observed. We conclude that this was a successful method to prevent secondary recurrence in the management of recurrent pterygium patients under 40 years of age.

Abstract
Fine needle aspiration cytologic findings in two cases of malignant lymphoepithelial lesion (MLEL) of the parotid glands are presented. Aspirates of both cases showed individual or cohesive clusters of tumor cells intermingling with mature lymphocytes. Cervical lymph node aspirates in both cases were similar to those seen in the parotids. Our findings suggest that neither cytology nor histology of the cervical lymph nodes is conclusive in establishing the primary site of a metastatic lymphoepitheliomalike carcinoma. MLEL of the salivary glands must be included in the differential diagnosis.

Abstract
The aim of this study was to investigate the incidence of different teat lesions in cows that cause obstruction of milk flow. 18,400 teats were palpated in Konya slaughterhouse. From these 1000 hard milking or obstructed teats were found (5.4%). Based on the radiographical results, distal 1/3, proximal 2/3, complete teat lesions and congenital obstructions were found in 70.1, 16.6 and 0.7% respectively.
