Abstract

Lead contamination occurs through air pollution and industry, enter the body through respiratory and digestive tract. High lead content will accumulate and affect adversely the cognitive function, causing neuropsychological dysfunction, encephalopathy, hyperactivity and other problems in children, disrupt the central nervous system and the immune system of children as well. This experimental research was randomized control group post-test only design. The experiment used of 27 pregnant mice, divided into three groups: negative control group, which were given distilled water, positive control group were exposed only to lead and the third group were exposed to lead and administered ascorbic acid. 25 mg/kg/day/orally neutral lead acetate was given during gestation day 7 to 16, and ascorbic acid 64 mg/kg/day/orally, started on gestation day 9 to 16. Treatment group with ascorbic acid supplementation had the lowest CYP1A1 enzyme activity compared to positive and negative control groups. This results confirmed by the molecular weight of CYP1A1 enzyme ranges 53.7 to 59.2 kDa, and the western blotting test showed the same thin band both two groups. The lowest of the average lead concentration in the head of fetal mice was found on the group of mice that treated with vitamin C. Supplementation of ascorbic acid can protect the liver and fetuses, by suspected mechanism that ascorbic acid could chelate the lead and excrete it via urine.

Abstract

The objective of this study was to determine time of neural fold fusion at dorsal mid line neural axis after treatment 2-methoxyethanol (2-ME) to pregnant mouse during neurulation period and to observe relation process of point of neural fold fusion. Mice at 08:05 gestational days treatment with 2-ME dose 7.5 mmol/kg bw on the other hand control group injected with aqua bidest. Pregnant mice at 08:12, 09:00, 09:12 was sacrificed by dislocation cervix. Embryo was collected after observe with dissecting microscope for external morphology and fixation in Bouin solution and buffer formalin for histological preparation and immunohistochemistry process. Result showed that there was failure of first point neural fold fusion at junction of perspective fore brain and mid brain. The failure of neural fold fusion was caused by increasing apoptosis neuroepithelium. There were no relation process between first point of neural fold fusion and second point or another point of fusion. Failure of first point fusion not cause failure another point of fusion. Observation at 09:12 gestational days showed that the only first point fusion was still open but formation of another part neural tube have finished.

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

Our previous experiment showed that prenatal exposure of rats to X-radiation in the late gestation period causes heterotopic Purkinje cells in the internal granular layer (IGL) of the cerebellum. The present study demonstrated precisely the involvement of Reelin in the aligment of Purkinje cells, which are different in severity between anterior and posterior lobes. Pregnant rats were exposed to 2.5 Gy X-radiation on gestation day 21 and the cerebellum of progeny was examined histologically and by immunohistochemistry of IP3 Receptor to identify Purkinje cells. By P8, while Purkinje cells with well developed dendrites aligned underneath the EGL in the control cerebellum, Purkinje cells with shorter and abnormally oriented dendrites failed to align and remained in the heterotopic location in the IGL of the anterior lobes but a small number of heterotopic Purkinje cells formed in the posterior lobes of the irradiated rats. Our previous published Reelin is present in the premigratory zone of the EGL and IGL in the control cerebellum. It decreased in the irradiated cerebellum on P1 to P8, especially the anterior lobes, however in posterior lobes on P8 Reelin level compared to the control (Darmanto, 2003). It is thus indicated that anterior lobes are more sensitive to X-radiation than posterior lobes and the different levels of Reelin between anterior and posterior lobes caused by X-irradiation may contribute the different susceptibility in induction of derangedPurkinje cells.

Abstract

This study was designed to identify the effects of nicotine on the skeletal and internal organ abnormalities of mice prenatally. Seventy two female mice strain Balb/C were used. Pregnant mice on gestation days (GD) 8, 10, and 12 was injected intraperitoneally with 3, 6, and 12 mg/kg BW nicotine respectively. Control nice was injected by aguabidestylata. On GD 18, and all of pregnant mice were sacrificed, and a half of living fetuses were immersed in Bouin’s solution to observe their internal organs, while another half were immersed in 95% ethanol to observed sekeletal malformation using alizarin red S staining. Results were analyzed using SPSS program version 11 for personal computer.The results showed that nicotine caused Skeletal malformation, especially in the sternum when administered on GD 8 and 10, in doses of 3 and 6 mg/kg BW, delayed of ossification was observed in the supraoccipital and sacrocaudal bones on GD 10 and 12 and doses of 12 mg/kg BW, while in the extremitas the malformation was observed in the proximal and medial phalanx both in the fore and hind limb especially on GD 10 and 12, and doses of 6 and 12 mg/kg BW. Nicotine was effects on the brain development especially hydrocephalus was observed on GD 8 and doses 10 and 12 mg/kg BW. Another internal malformation such as ectopic renalis was observed on GD 8 and doses of 3 and 6 mg/kg BW. These finding suggested that nicotine has caused skeletal malformation, brain malformatin and ectopic renalis, when administered in mice prenatally.

Abstract

Our previous experiment showed that prenatal exposure of rats to X-irradiation on gestation day 21st as the late gestation period causes heterotopic Purkinje cells and abnormal foliation of the cerebellum. However the present study observed the heterotopik of Purkinje cell layer following exposure of the rats to X-irradiation on postnatal day (P) 4, without abnormal foliation of the cerebellum. It also demonstrated the process of re-derangement of Purkinje cells. Rat pups were exposed to 2.5 Gy X-irradiation and the cerebellum was examined histologically and by immunohistochemistry to identify Purkinje cells. At 6 h after exposure, extensive cell death was observed in the external granular layer (EGL) of the cerebellum. By P7 (3 days after exposure), while Purkinje cells with well developed dendrites aligned underneath the EGL in the control cerebellum, Purkinje cells with shorter and abnormally oriented dendrites failed to align and re-deranged in the heterotopic location. On adult, the cerebellum of rats irradiated was observed almost normal folial developed. It is strong support previous study that the critical stage for cerebellar abnormal foliation caused X-irradiation is in the early postnatal period.

Abstract

Rasbora (Rasbora sp.) is one of the endemic freshwater fish species in East Java, which is currently being threatened due to environmental degradation, human activities and pollution. In East Java, it is known that there are several species of Rasbora (Rasbora sp.). Domestication is one method to preserve Rasbora in East Java, preceded by identifying potential species of Rasbora sp. from the natural catchment. This study aims to determine the diversity of Rasbora sp in East Java. Samples were taken at five different locations, specifically: Nganjuk (Brantas Watersheds), Ngawi (Bengawan Solo Watersheds, Silowo Springs Tuban, Umbulan Springs Pasuruan and the Setail Watersheds Banyuwangi. The main parameters observed were morphology and morphometry. The morphological analysis used identification guidelines, while morphometric data were obtained through 15 parameters measurement then analyzed using one-way Anova test on SPSS 25 software. Based on the morphological and morphometric analysis, it is known that the species of Rasbora in Nganjuk and Ngawi regencies are Rasbora argyrotaenia and the species of Rasbora in Tuban, Pasuruan and Banyuwangi regencies are Rasbora lateristriata. One-way Anova test showed Rasbora from the five locations were significantly different based on the result value of p<0.05.

Abstract

Indonesia is the largest exporter of eel to consumer countries such as European, America, Taiwan, Japan, South Korea, and the Middle East. Eels are catadromous fish that are in the growth phase in fresh waters and the development phase is in marine waters. Meristic measurement is done by counting the spine (vertebrates). Eel morphometric measurements include TL (Total Length), HL (Head Length), PDL (Pre-Dorsal Length), PAL (Pre-Anal Length) and ADL (Ano-Dorsal Length). The purpose of this study was to analyze the morphological, morphometric, and meristic diversity of intraspecies between populations. Based on the research, the samples identified were morphologically almost the same between the populations, this was seen from the color patterns in the form of plain black or brown and short fins. The morphometric and meristic measurements in the 3D distribution plot still appear to be clustered in one population, while in the dendrogram clade, one species is still congregated in each. The results of the interpretation of the matrix plot of the lowest diversity are the length and number of anodorsal vertebrate segments. This observation can be concluded that the TL and TV of the eel varied, while the PDL, PAL, PDV, PAV, ADV showed the intraspecies character of A. bicolor. This is because the distribution of A. bicolor eels that inhabit the waters of Java Island is widely distributed and random (panmitic).

Abstract

Sugarcane Mosaic Virus (SCMV) infection is one of the most serious problems that can result in severe yield loss of sugarcane. Since the symptoms of SCMV infection are similar to other biotic and abiotic stress symptoms, the development of a rapid diagnostic with high precision is required. The use of laboratory animals such as rabbits is required for antibody production in immunoassay‐based detection. However, due to its many advantages, specific chicken egg yolk immunoglobulin (IgY) has received considerable attention as an alternative antibody production in immunodiagnostics for infectious diseases. In this study, IgY antibody against SCMV recombinant coat protein (CP) was successfully obtained from chicken blood serum and tested to compare its efficacy against antibody from rabbit (IgG) using immunocapture reverse transcription‐polymerase chain reaction (IC‐RT‐PCR). The result showed that IgY and IgG could detect 0.1 g SCMV infected leaves using 1000‐times‐diluted antibodies. The IgY antibody was also confirmed to be reproducible and potentially applicable in plant disease diagnostics using an antibody‐based detection.
