Turkish Journal of Medical Sciences

Aim: Studies about relationships between diabetes mellitus, diabetic complications, and cognitive functions have been initiative factors for this study. We evaluated various relations between procedure of the disease, diabetic complications, and cognitive functions among diabetic subjects. Materials and methods: Type-2 diabetic patients were evaluated for their disease status, complications, and cognitive functions (by Mini Mental State Examination (MMSE) test). We compared MMSE results of the patients with the control group. Results: We evaluated 75 patients with type-2 diabetes mellitus and 49 control subjects. Orientation (P = 0.006), attention and calculation (P = 0.002), and total (P < 0.001) scores of the control group were significantly greater compared to the diabetic group. We observed negative correlation between the length of disease and cognitive functions within the diabetic group. Recall scores of the diabetic subjects with 6 and less HBAIC levels were significantly greater than those with 6.1 and greater levels (P = 0.049). We observed negative relations between registration scores and retinopathy, but not between orientation and total scores and hypertension among diabetic subjects. Conclusion: Type-2 diabetes mellitus may destroy cognitive function. Length of disease, high serum HBAIC levels, hypertension, and retinopathy are significant additional risk factors. We conclude that cognitive function assessment should be routine procedure in the management of type-2 diabetes mellitus.

Effects Of Ramadan Fasting On Stroke, Selçuk Çomoğlu, Ahmet Temi̇zhan, Emel Peşi̇nci̇, İzzet Tandoğan, Şenay Özbakir

Turkish Journal of Medical Sciences

The effects of fasting on humans have not been adequately investigated. Ramadan fasting is a great opportunity for scientific research due to its peculiar nature. With this in mind, we conducted research on the effects of Ramadan on stroke, which is one of the most common causes of death in adults. Patients hospitalized solely for ischemic stroke and intracerebral hemorrhage were evaluated retrospectively. The ratio of these cases to other patients hospitalized in the neurology department was determined. The in-hospital clinical course and mortality rates of the patients with stroke were evaluated. Within the entire cohort, the most frequently encountered …


A Cell Protective Mechanism In A Murine Model Of Parkinson's Disease, Emi̇n Öztaş, Turgut Topal Jan 2003

A Cell Protective Mechanism In A Murine Model Of Parkinson's Disease, Emi̇n Öztaş, Turgut Topal

Turkish Journal of Medical Sciences

Parkinson's disease is characterized by progressive degeneration of the dopaminergic (DA) neurons in the substantia nigra (SN). However, the mechanism underlying DA cell death remains unclear. While apoptotic cell death has been implicated in DA cell death in Parkinson's disease, autophagy - a regulated cellular process for degrading intracellular proteins and organelles under stress - in Parkinson's disease is not known. Here, we report evidence of autophagy in DA neurons of the SN in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of Parkinson's disease. Mice were treated with saline or MPTP (40 mg/kg) and sacrificed after 7 days, and brain tissue samples were …

The Role Of Vasopressin In Reduced Renalmass-Saline Hypertension, Besim Özaykan, Ayşe Doğan

Turkish Journal of Medical Sciences

The cause of reduced renal mass (RRM)-saline hypertension is not clear. In our study, it was aimed to investigate the role of vasopressin (AVP) in this type of hypertension by using selective V 1 antagonist of AVP. RRM was performed in 32 normotensive male Wistar rats under anesthesia in which we used a mixture of ketamine (130 mg/kg, i.m.) and chlorpromazine (1.3 mg/kg, i.m.).
