Abstract

BACKGROUNDSleep deprivation is a significant problem among adult men and is considered as a risk factor for several diseases. Paradoxical sleep deprivation (PSD) induces Leydig cell apoptosis through elevation of corticosterone, with testicular malondialdehyde (MDA) and Leydig cell caspase-3 expression as parameters. The aim of this study was to observe testicular MDA level and caspase-3 expression treated with paradoxical sleep deprivation (PSD), immobilization, and footshock stress and to determine the stress model with a significant effect in white male rats (Rattus norvegicus) . METHODSThis experimental randomized study of posttest only with control group design was conducted on 24 white male Wistar strain rats, randomly allocated into four treatment groups, i.e. control (K1) without any stress treatment, PSD (KII), immobilization (KIII), and footshock stress (KIV). Treatments were given for 25 days to produce chronic stress. Testicular MDA concentration was examined by the ELISA method while caspase-3 was examined by the TUNEL method.RESULTSMean testicular MDA concentration with one-way ANOVA test showed differences in means between the groups (p=0.000) and post hoc Tukey-HSD test showed significant results between PSD stress group versus control, immobilization and footshock stress groups. One-way ANOVA test showed a significant difference in caspase-3 expression in at least two treatment groups (p=0.008) and post-hoc Tuckey-LSD test showed significant differences between controls and all stress groups. CONCLUSIONSleep deprivation is a type of stress inducing changes in testicular MDA concentration and caspase-3 expression in male rat testes.

Abstract

BACKGROUND Chronic stress increases glucocorticoid levels and accelerates reduction in Leydig cells functions and numbers. Chronic stress models in the working place comprise sleep deprivation, sedentary stress, and physical stress. The aim of this study was to evaluate the effect of various work stress models, such as stress from paradoxical sleep deprivation (PSD), immobilization, and footshock, on serum testosterone levels and number of Leydig cells in male albino rats. METHODS This study was of experimental randomized post-test only with control group design using 24 male Wistar albino rats (Rattus norvegicus). The sample was divided into 4 groups: K1 (control), K2 (PSD), K3 (immobilization) and K4 (footshock), receiving treatment for 25 days. Measured parameters were serum testosterone level and Leydig cell number. Analysis of variance (ANOVA) was used for statistical analysis, followed by post hoc LSD. RESULTS Mean serum testosterone levels (0.07 ± 0.08 ng/ml) and Leydig cell numbers (4.22 ± l0.96) were lowest in the PSD stress model. Serum testosterone levels differed significantly between controls and PSD group (p=0.014), while there was a significant difference in numbers of Leydig cells between footshock stress and PSD (p=0.011) and between the three stress groups and controls (p=0.006). CONCLUSION This study demonstrated that PSD, immobilization and footshock stress significantly decreased serum testosterone levels and number of Leydig cells in male albino rats (Rattus norvegicus). The mechanism by which PSD affects serum testosterone is still unclear.

Abstract

BackgroundHypertension is associated with endothelial-dependent vasodilation disorders, due to reduced nitric oxide (NO) availability and excessive angiotensin II (ANG-II) activation. The objective of this study was to determine the association between matrix metallopeptidase 9 (MMP-9) gene polymorphism and hypertension in ethnic Javanese in the 40-80 year age group. MethodsThis was a case-control study on 50 PROLANIS patients of family doctors meeting the inclusion criteria and 50 controls without hypertension. Subjects were hypertensive patients with constant systolic arterial pressure of >140 mmHg and diastolic arterial pressure of >90 mmHg, confirmed in three successive measurements The observed parameters were degree of MMP-9 polymorphism, and NO and ANG-II levels. Matrix metallopeptidase 9 polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) using the SmaI restriction enzyme. MMP-9 polymorphisms were indicated by variation in band patterns. Degree of polymorphism in cases and controls were compared with NO and ANG-II levels in both groups. Data analysis was done using independent t-test.ResultsThe heterozygous (3 band) to normal (2 band) MMP-9 genotype ratio was 3:1 in hypertensives, but balanced in controls. In hypertensives, heterozygous GA and homozygous AA genotype frequencies were respectively 3.198 and 1.548 times higher than that of the GG genotype (p=0.008 and p=0.726). There was a statistically significant differences of NO and Ang-II levels between cases and controls (p=0.000 and p=0.000; respectively). ConclusionMatrix metallopeptidase 9 gene polymorphisms in hypertensive ethnic Javanese are associated with NO and angiotensin II levels.
