The aim of this work was to analyze the cell proliferation and apoptosis indexes on the 18 and 21 days of pregnancy of diabetic rats and to correlate with maternal glycemia and perinatal outcomes. Placentas from 20 Wistar rats were collected and divided into four experimental groups: control and diabetic of 18 and 21 days of pregnancy. The cell proliferation was analyzed using the PCNA expressi...

Purpose: The aim of the study explores probable toxic effects vancomycin on kidney and analysis protective melatonin.
 Materials Methods: In this study, rats were randomly divided into 4 groups: control group; melatonin (10 mg/kg/day) vancomycin-treated (200 mg/kg) + group. Rats in treatment group given two doses a day with an interval seven consecutive days once daily for days. experiment...

Mesangial cell (MC) injury is a characteristic feature in the early phase of Thy.1 nephritis. The present study investigates the contribution of complement to MC apoptosis in this experimental model of kidney disease in rats. Thy.1 nephritis was induced by injection of mouse anti-Thy.1 monoclonal antibody (ER4G). To assess the contribution of the terminal sequence of complement on apoptosis, th...

BACKGROUND Osteonecrosis of the femoral head is classified into idiopathic and secondary forms. A number of etiological factors in the development of osteonecrosis have been suggested but the biological mechanisms are still unclear. Recently, some reports suggested that the apoptosis is closely related to osteonecrosis of the femoral head. Therefore, this study examined the expression of apopto...

Background—The terminal transferase uridyl nick end labelling (TUNEL) assay allows the easy demonstration of cell death as a result of apoptosis. However, when this assay is applied to liver tissue, the number of TUNEL positive cells is dependent on the time of incubation with proteinase K. Aim—To test whether false positive results are the result of the release of endogenous endonucleases by p...

Objective: Even if epileptic women can give birth to healthy babies, the rates of premature birth, low weight, fetal and neonatal death risk, congenital malformations growth retardation in pregnant who use antiepileptic drugs (AEDs) are high compared population. The present study aimed examine effects AED Lacosamide (LCM) during pregnancy on fetus terms neuronal embryonic development 48-hour ch...

After birth, constriction of the full-term ductus arteriosus induces oxygen, glucose and ATP depletion, cell death, and anatomic remodeling of the ductus wall. The immature ductus frequently fails to develop the same degree of constriction or anatomic remodeling after birth. In addition, the immature ductus loses its ability to respond to vasoconstrictive agents, like oxygen or indomethacin, wi...

OBJECTIVE We investigated apoptosis, i.e., programmed cell death, in steroid induced osteonecrosis in a rabbit model. METHODS Forty-four adult Japanese White rabbits were divided into 3 groups: Group A were untreated controls and had a subsequent 8 week no-treatment period; Group B received intramuscular injection of methylprednisolone 4 mg/kg once weekly for 4 weeks; and Group C received the...
