    Neuroendocrine Tumors. Four Case Reports

    Acta Endo (Buc) 2015 11(1): 116-123 doi: 10.4183/aeb.2015.116

    Abstract
    Context. Neuroendocrine tumors are tumors developing from primitive cells in the intestinal walls, but can also affect the lungs, liver, pancreas, ovaries. Objective. We aim to describe the clinical, imagistic and biologic aspect of neuroendocrine tumors with different localizations and present the evolution, treatment options and prognosis. Design. Four patients either with previously known neuroendocrine tumors or with newly discovered tumors were studied. Subjects and methods. The first patient was diagnosed with primary liver carcinoid with pulmonary metastases by abdominal and thoracic CT scan, liver biopsy and determination of serologic markers. The second patient was diagnosed with primary lung neuroendocrine tumor using thoracoscopy biopsy and serologic markers The third patient was diagnosed with a large gastric neuroendocrine tumor with liver and spleen metastases. using CT scan, MRI and biopsy from the abdominal mass. The fourth patient was diagnosed with primary liver carcinoid using imagistic methods (CT scan) and liver biopsy. Results. The first patient died after 4 months due to the extent of the disease and comorbidities. The second patient had a good evolution, as the tumor was diagnosed in a localized stage. The third patient had a decreased survival due to the dimensions of the primary tumor and the multiple liver metastases which later caused obstructive jaundice requiring external biliary drainage. The fourth patient has had a good evolution, the tumor masses in the liver are being kept under control using transarterial chemoembolization. Conclusion. Neuroendocrine tumors are very versatile both in location and clinical aspect. The diagnosis requires imagistic methods but it is imperative to perform biopsy of the lesions with special histologic stains in order to be sure of the diagnosis.

    The Effect of Hsp60 on Fertilization and Pre-Implantation Embryo Development in Mice: an in Vitro Study

    Acta Endo (Buc) 2019 15(2): 153-157 doi: 10.4183/aeb.2019.153

    Abstract
    Context. Heat Shock Protein 60 (HSP60) is a chaperone protein which is involved in proteins transfer and re-folding of proteins. Objective. Importance of HSP60 in sperm capacitation and facility of sperm-oocyte membrane binding was confirmed, therefore in this study the effect of HSP60 on the rate of in vitro fertilization and the cleavage rate in mouse embryo was investigated. Design. Ten male mice and twenty five female mice were involved to collect sperms and oocytes required for this study. Subjects and Methods. Sperms were collected from the epididymis of male mouse and oocytes were collected from the oviduct of female mouse following ovarian hyperstimulation. Then, capacitated sperms and oocytes were placed together in fertilization medium in four groups in the presence of different concentrations of HSP60 (10, 50 and 100 ng/mL) and in the absence of HSP60. After calculation of the fertilization rate, zygotes were transformed into the other medium for development and the cleavage rate was monitored to blastocyst stage. Results. There was not a significant difference in the rate of fertilization between 10 ng/mL HSP60 group and the control group. The rate of fertilization and two-cell embryo development decreased significantly (P≤0.05) in 100 ng/mL HSP60 compared to other experimental and control groups. Further, the rate of two-cell embryo development increased significantly (P≤0.05) in 10 ng/mL HSP60 compared to other experimental and control groups. Conclusions. The present study demonstrated that HSP60 in low dose had a positive effect on two-cell embryo development, however it did not have any significant effect on the fertilization rate. Conversely, HSP60 had adverse effects on the fertilization and cleavage rates at higher doses.

    Oxidative Stress is Markedly Reduced by Combined Voluntary Exercise and Testosterone in the Heart of Diabetic Rats

    Acta Endo (Buc) 2019 15(2): 173-181 doi: 10.4183/aeb.2019.173

    Abstract
    Objective. Cardiovascular disorders in diabetes condition arise from increased oxidative stress. Both regular mild exercise and testosterone influence on body’s antioxidant system in diabetes. In this study, we evaluated treatment of testosterone and voluntary exercise, alone or together on oxidative stress in the heart and blood of diabetic rats. Methods. Type 1 diabetes was induced by intraperitoneal injection of 50 mg/kg of streptozotocin in rats. Sixty three rats have been divided into eight groups as follows: Diabetes, diabetes+ testosterone, diabetes+ exercise, diabetes+ testosterone+ exercise, diabetes+ castration, diabetes+ castration+ testosterone, Diabetes+ castration+ exercise, Diabetes+ castration+ exercise+ testosterone. Type 1 diabetes was induced by intraperitoneal injection of 50 mg/ kg of streptozotocin in the male Wistar rats and after a week, castration was performed. After 42 days of treatment with testosterone (2 mg/kg/day) or voluntary exercise alone or in combination, SOD, GPX and CAT activities and MDA levels were measured in the blood and heart tissue samples in the groups of study. In the end of study, SOD, GPX and CAT activities and MDA levels were measured in blood and heart tissue samples in the groups of study. Results. SOD, GPX and CAT activities significantly (p<0.05) increased in groups that treated either testosterone or exercise and MDA level significantly (p<0.01) decreased in the blood and heart tissue of diabetic and castrated diabetic rats. Simultaneously, treatment with testosterone and exercise had a synergistic effect on antioxidant enzymes level in diabetic and diabetic castrated rats. In the castrated animals with diabetes, SOD, GPX and CAT activities significantly decreased (p<0.05) and MDA levels significantly increased (p<0.05) in blood and heart tissue. Conclusion. Voluntary exercise and testosterone alone or together heightened body’s antioxidant system and were able to reduce the MDA levels in blood and heart of diabetic and castrated diabetic rats.

    The Effect of Testosterone and Voluntary Exercise, Alone or Together, on miRNA-126 Expression Changes in Heart of Diabetic Rats

    Acta Endo (Buc) 2017 13(3): 266-271 doi: 10.4183/aeb.2017.266

    Abstract
    Methods. Ninety Wistar male rats were used in this study. Type 1 diabetes was induced by i.p injection of 50 mg/kg of streptozotocin in all animals. After 42 days of treatment with testosterone (2mg/kg/day) or voluntary exercise alone or in combination, the heart of the rats has been removed and MicroRNA was extracted from the heart using miRCURYTM RNA isolation kit. Results. Our results showed that either testosterone or exercise increased miRNA-126 expression levels in the heart of diabetic rats. Treatment of diabetic rats with testosterone and exercise at the same time had a synergistic effect on miRNA-126 levels in the heart. Furthermore, in castrated diabetes group, miRNA-126 levels were significantly decreased in heart, whereas either testosterone treatment or exercise training enhanced expression of this miRNA. Also, simultaneous treatment of castrated diabetic rats with testosterone and exercise had an additive effect on miRNA-126 expression levels. Conclusion. This study showed that testosterone and exercise promote an increase in the expression of miRNA-126 in the heart tissue and this may be related to cardiac angiogenesis. These results may indicate that testosterone and exercise can help to prevent progression of diabetic cardiomyopathy due to impaired angiogenesis in the heart.

    Acute Hepatitis after Methimazole. Case Report

    Acta Endo (Buc) 2014 10(2): 267-272 doi: 10.4183/aeb.2014.267

    Abstract
    Background. There are few cases of methimazole induced hepatitis. The mechanism is probably related to the fact that it is a hepatic- metabolised drug. Objective. To demonstrate the fact that an acute cholestatic hepatitis can be triggered by methimazole. Design. While dealing with a major cholestatic syndrome with cytolysis, we performed the following steps: correct and complete history, serum detection of acute viral hepatitis, an autoimmune cause and finally liver biopsy. Subjects and Methods. We present the case of an 80 year old woman, with a history of hyperthyroidism, in treatment with Methimazole. After a month, the patient developed jaundice, for which she was admitted to our clinic. On admission she presented an important cholestatic syndrome, with elevated transaminases (5 times normal). Results. None of the laboratory tests indicated a possible viral infection or autoimmune disease. Abdominal ultrasound revealed no possible obstruction of the biliary system. Ultimately we performed a liver biopsy, which revealed inflammatory infiltration and cholestasis. Conclusion. We conclude that the hepatitis was induced by methimazole. Corticotherapy was initiated, with a relatively slow but favourable evolution. I131- Radiation therapy was elected for the treatment of hyperthyroidism.
