Abstract

This study aims to determine the effect of administration of Etlingera hemispharica leaf extract on white rats (Rattus norvegicus) induced by mercury chloride as seen from the histopathological description of the testes. The research method used is experimental post-test-only control group design. The extract was administered for seven days by gavage. Testicular organ harvesting was carried out on the 9th day after the rats were euthanized and continued with making testicular preparations. Testicular damage was assessed using the Johnsen score. Data were analyzed using non-parametric statistical tests. The results showed that the test groups had a p-value of 0.000. The histopathological description of the testes induced by HgCl2 had a p-value of 0.005 and the administration of E. hemisphaerica leaf extract in HgCl2-induced mice showed a p-value of 0.008. In conclusion, administration of E. hemisphaerica leaf extract to R. norvegicus induced by mercury chloride improved spermatogenesis on the histopathological features of the R. norvegicus testes.

Abstract

This study aims to identify the VEGF-A gene polymorphism (rs2010963) in the first generation of patients with coronary heart disease (CHD) and non-CHD in Bengkulu City. The method used is molecular analysis of polymorphism through Polymerase Chain Reaction Restriction Fragment Length Polymorphism (PCR-RFLP). This type of research is descriptive observational with a cross-sectional research design. The results of this study indicate that the genotype frequency of the VEGF-A gene polymorphism (rs2010963) in the first generation of patients with CHD is genotype CC = 11 (52.4 %), GG = 7 (33.3%) and CG = 3 (14.3%). ). The distribution of the VEGF-A genotype (rs2010963) in the first non-CHD offspring, namely GG = 9 (42.9%), CC = 7 (33.3%) and GC = 5 (23.8%). The statistical analysis results showed that the p-value obtained was 0.460 for the VEGF-A gene polymorphism genotype (rs2010963) in the first CHD and Non-CHD derived samples. In conclusion, there was no significant difference in the VEGF-A gene polymorphism in the first generation of CHD and non-CHD groups in Bengkulu City.
