Abstract

2-Methoxyethanol (2-ME) and glycol esters are widely used as a solvents in the industry and plasticizers, and have becomes ubiquitous environmental pollutants. This study were designed to evaluate the malformation of brain development as an impact of 2-ME. Four groups of pregnant mice were injected to 2-ME dose 10 mmol/kg body weight at 7, 13, 15, and 17 days gestation respectively. Control group were injected with sterile water. At 18 days of gestation samples in groups 7 and 13 days gestation were sacrificed. Brain were remove and weight, morfologically and histologically were examined. Samples were divided into five groups, i.e. control group, 7th, 13rd, 15th and 17th days of gestation groups. Samples in 7th and 15th days of gestation groups killed in 18th days of gestation to observed fetal brain defect and decreased of fetal brain weight but some samples to allow delivery of fetuses. Furthermore, the fetuses killed on 0, 5, 10, and 20 days after birth, to take their brain. The result of these study showed that there are decreasing total weight of fetal brains and there are cerebral malformation as impact of 2-ME exposure.

Abstract

This research has done to investigate the effect of 2-Methoxyethanol on the testicular histology of the male mice and also the influence the length of time after administration 2-ME stopped in the recovery of the spermatogenic cells and the diameter also the thicknes of seminiferous tubule. Thirty BALB/C male mice 8–9 week old, weighed 28–30 grams body weight. Those mice separated to 6 groups with 5 male mice each group. Those mice were treated with 2-ME 200 mg/kg body weight daily by intra peritoneal injection, within 3 weeks (K1). To investigate the influence the length of time after administration 2-ME stopped, the male mice after treated by 2-ME in 3 weeks also given by the length of time after 2-ME administration stopped 1, 2, 3 and 4 weeks (P1, P2, P3 and P4). The control animal given by intraperitoneal administration of saline. Histological observation was performed on the number of spermatogonium, primary spermatocyte, oval spermatid and the diameter also epithelial thickness of seminiferous tubules. The data were analyzed by One-Sample T-test to investigate the differences between K0 and K1. One Way ANOVA to investigate the influence the length of time after 2-ME administration stopped in the P1, P2, P3 and P4 and then continuing by LSD (Least Significant Difference) to show the differences groups of treatment. The result showed that administration 2-ME could destroy the seminiferous tubules in the testes. Its presented by the decreasing of the number spermatogonium, primary spermatocyte, oval spermatid and diameter also epithelial thickness of seminiferous tubule. The length of time after administration 2-ME stopped could recover seminiferous tubules condition. Its presented by the increasing of the number spermatogonium, primary spermatocyte, oval spermatid, and diameter also epithelial tickness of seminiferous tubules. The conclution of this research were, 2-ME could destroy the testicular histology of the male mice and the length of time after administration 2-ME stopped have linear correlation with seminiferous tubules recovery.

Abstract

Shiitake mushroom (Lentinus edodes) is one of the wood mushroom types that can be consumed as a food as well as for a medical purpose. Lentinan, a polysaccharide contained in shiitake, is well known for its use on cancer medication. Mycelium of Shiitake mushroom contains lentinan the same as other part of the mushroom like fruity body. Toxicity of the lentinan in mycelium compare to the fruity body has been first conducted by using Brine Shrimp Lethality Test (BST). Using Potato Dextrose Broth media with the growth rate of 3.88% did mycelium multiplications. Probit analysis showed that the toxicity of the mushroom’s cap, stem, and mycelium of Shiitake mushrooms is LC50 = 648.76507 mg/ml LC50 = 489.39444 mg/ml, and LC50 = 481.16941 mg/ml respectively.

Abstract

DNA in human’s sperm is located in nucleus (nDNA) and mitochondria (mtDNA). DNA oxidation is indicated from high concentration of 8-OH-dG. It is very important to identify factors that can cause genetic dysfunction risk responsible for genetic changes. 8-OH-dG compound are a promutagenic of DNA dysfunction of deoxyguanosine oxidation by oxygen radical. ROS is an oxidation, which in high concentration can oxidize DNA. Guanine is a nucleotide, which prone to oxidation, with 8-OH-dG as the end product. Detection of 8-OH-dG can be done by HPLC method. These results indicated that there were significant differences (p < 0.01) in detection of 8-OH-dG in sperm, between normospermia with asthenospermia and normospermia with oligospermia. Correlation (r) of 8-OH-dG with motile spermatozoa is – 0.7111. Immotile spermatozoa caused by oxidation or DNA damage are shown by high concentration of 8-OH-dG. In normal physical condition, sperm produces oxidant. High oxidant is toxic to sperm, which influence their motility. Sperm’s motility is one of factors causing male infertility.

Abstract

The purpose of this experiment was to study the effect of turmeric (Curcuma xanthorrhiza) rhizome infuse to hemoglobin concentration and number of erythrocyte of [(PbNO3)2] treated rats. Pb was presumed to be link at sulphyhydril groups that may caused an inhibition to several enzymatic process, such as d-ALAD and heme sintetase which is caused the inhibits of Hb synthesis and erythropoesis. Twenty female rats was used in this experiment. They were divided into five groups, i.e. (A) control (treated with 1 ml aquadest); (B) treated with 1/2 ml of 12 ppm lead solution and 1/2 ml aquadest; (C) treated with 1/2 ml of 12 ppm lead solution and 1/2 ml of 20% turmeric rhizome infuse; (D) treated with 1/2 ml of 50 ppm lead solution and 1/2 ml aquadest; (E) treated with 1/2 ml of 50 ppm lead solution and 1/2 ml of 20% turmeric rhizome infuse. The treatment was given orally every day (30 days) using a modified syringe. After 30 days of treatment, the blood sample were taken about 2 ml by heart puncture. The Hb concentration was determined using by Cyanmethemoglobin method and number of erythrocyte was counting on Haemocytometer Improved Neubauer. Data were analyzed by Anova and LSD test (α = 0.05). The results of this study shows that 20% of turmeric rhizome infuse statistically has a significant effect (P < 0.05) to increasing of hemoglobin concentration but hasn’t significant to prevent the number of erythrocyte decreasing of [(PbNO3)2] treated.
