The present study aims to examine how zinc and testosterone supplementation, in combination and separately, affect plasma LH, FSH and leptin levels in castrated rats. Eighty experimental animals used in the study were allocated to 8 groups, each containing an equal number of rats. Group 1, control group; Group 2, castration group; Group 3, testosterone group (5 mg/kg/day); Group 4, zinc-supplemented group (3 mg/kg/day); Group 5, testosterone and zinc-supplemented group; Group 6, zinc-supplemented castration group; Group 7, testosterone and castration group; and Group 8, zinc-supplemented, testosterone and castration group.

Pinealectomy increases oxidant damage in kidney and testis caused by hyperthyroidism in rats.

Thyroid hormones regulate energy metabolism and act on mitochondria which are an important source of free radicals in the cell. The pineal gland activates antioxidant systems via melatonin secretion and thus has a protective function in body tissues. The present study was conducted to determine the oxidative damage caused by hyperthyroidism in kidney and testis tissues of pinealectomized rats.

Suppurated mediastinal and cardiac echinococcosis: report of a case.

We herein report the case of a suppurated mediastinal and cardiac hydatid cyst which occurred after the initial treatment of the patient for a primary mediastinal hydatid cyst in a radiology department. Both extracorporeal circulation and total circulatory arrest were used during the operation. We believe that surgery is the only feasible treatment for hydatid cysts located in the mediastinum, and surgery should be urgently performed whenever a possible rupture is suspected in order to avoid a possible anaphylactic reaction, mediastinal suppurations leading to serious complications, and growth into the pleural cavity.

The effect of thyroxine administration on lipid peroxidation in different tissues of rats with hypothyroidism.

Thyroid dysfunctions bring about pathological changes in different organs of the body. Findings obtained from in vivo and in vitro studies point out that thyroid hormones have a strong impact on oxidative stress. The present study was conducted to demonstrate how high-dose thyroxin administration for one week affected oxidative damage formed in experimental hypothyroidism.

The aim is to examine histopathological changes and expression of epidermal growth factor receptor (EGFR) in tracheal epithelia caused by application of topical mitomycin-C (MMC) in rabbit model after the tracheotomy procedure. The conventional tracheotomy was performed in 16 rabbits. They were randomly divided into two equal groups.

The effects of zinc and/or melatonin deficiencies on cellular immunity were investigated in rats infected with Toxoplasma gondii. A total of 50 adult male Sprague-Dawley rats were divided into 5 groups of 10 rats each. In group I, the rats were infected with T.

Effects of zinc deficiency and supplementation on plasma leptin levels in rats.

The effects of zinc deficiency and supplementation on plasma leptin levels were studied in Sprague-Dawley rats. After 6 wk on a zinc-deficient diet containing 0.65 ppm Zn/g, the mean body weight was significantly lower than that of normal or zinc-supplemented rats, which showed no difference among them.

Effect of off-pump and on-pump coronary artery bypass grafting on renal function.

Background: Coronary artery bypass grafting (CABG) with cardiopulmonary bypass (CPB) has the risk of renal dysfunction. The cause of renal dysfunction after CPB is multifactorial, such as nonpulsatile flow, renal hypoperfusion, hypothermia, and duration of CPB. This study compared off-pump technique with on-pump technique on renal function in patients who underwent CABG.

Preoperative analgesia management with rofecoxib in thoracotomy patients.

Objective: Pain management after thoracotomy is significant because pain reduces the postoperative respiratory performance. In this study, the analgesic efficacy and safety of rofecoxib in thoracotomy patients were evaluated.

Design: A prospective, randomized, double-blind, and placebo-controlled study.

Primary echinococcus infestation of the bone and muscles.

Hydatid diseases of the bone and muscles are rare, generally are incurable, and have a high level of recurrence. We attempted to ascertain whether the recurrence rate decreased in patients with hydatid disease infestation of the bone and skeletal muscle who were treated with current surgical techniques and antihelminthic chemotherapy, and whether the outcomes for bone infestation were different when compared with outcomes for muscular infestation. We retrospectively reviewed 15 patients with hydatid disease of the bone (eight patients) and muscle (seven patients).

Acute thrombosis of inferior vena cava in a pregnant woman presenting with sciatica: a case report.

A 20-year-old pregnant woman was admitted to our department with symptoms of deep venous thrombosis in the left lower extremity and excessive lumbar pain. Low-molecular-weight heparin was administered. She recovered with this treatment, however, severe lumbar pain continued.

Tracheopathia osteoplastica associated with iron deficiency anemia.

Tracheopathia osteoplastica (TPO) is a benign disease of trachea characterised by numerous cartilaginous or bony structures protruding into tracheobronchial lumen. We report a case of a 85-year-old male patient in whom tracheopathia osteoplastica was diagnosed incidentally during bronchoscopy which was missed on chest computed tomography examination. The patient also had iron deficiency anemia, the cause of which was not identified.

Effect of zinc deficiency and supplementation on lipid peroxidation of renal tissue in ovariectomized rats.

The aim of this study was to investigate how zinc deficiency and supplementation affects lipid peroxidation in the renal tissue in ovariectomized rats. Four study groups were formed with 10 Spraque-Dawley rats each. Two of the groups served as normal and ovariectomized controls; the other two were ovariectomized rats that were zinc deficient and zinc supplemented, respectively.

The influence of aldosterone on the development of left ventricular geometry and hypertrophy in patients with essential hypertension.

The identification of risk factors for the initiation of left ventricle hypertrophy (LVH), which is an independent risk factor for cardiovascular mortality and morbidity in hypertensive patients, is very important. The objective of the present study was to identify the relationship of aldosterone with LVH and different geometrical patterns of left ventricle that develop in patients with essential hypertension. A total of 83 patients with essential hypertension (44 females, mean age, 51 +/- 8 years, 39 males, mean age, 57 +/- 10 years) were included in this study.

Vena cubiti media for creation of a loop-shaped arteriovenous fistula at the elbow region.

Hemodialysis access is one of the major routes, for patients who need long-term hemodialysis. In this report, we tried a new secondary arteriovenous fistula technique. Between January 2000 and June 2003, hemodialysis access was created in more than 650 patients with end-stage renal failure at our institution.

Lemierre's syndrome associated with septic pulmonary embolism: a case report.

An 18-year-old female patient suffering from a painful right-sided neck mass was admitted to our emergency service. Computed tomography of the neck revealed thrombosis of the right internal jugular vein. Computed tomography of the chest indicated septic pulmonary emboli in both lungs.

Effects of gamma-hydroxybutyrate on cerebrospinal fluid lactate and glucose levels after spinal cord trauma.

This study aims to evaluate the effects of gamma-hydroxybutyrate (GHB) after spinal cord trauma (SCT). Twenty rabbits were divided equally into four groups: group I was the sham-operated group, group II suffered from SCT but received no treatment, group III was given a dose of 400 mg/kg of GHB intravenously before SCT and group IV received the same dose after SCT. Cerebrospinal fluid (CSF) samples were obtained 30 min before SCT (T(0)), at 60 (T(1)) and 120 min (T(2)) after SCT.

The clinical and surgical features of right-sided intracardiac masses due to echinococcosis.

Right-sided cardiac echinococcosis shows special clinical and surgical features beyond the rareness of echinococcosis in this position, leading to serious and life-threatening complications. We examined our cardiac hydatid cyst patients, retrospectively, and report our experience of the surgical treatment of right-sided cardiac hydatid cysts. Between 1985 and 2000, seven patients were transferred to our department from the cardiology department with a diagnosis of cystic cardiac masses which were highly suspected of being hydatid cysts.
