Objectives: Drugs can cause undesired effects on the fetus during pregnancy, especially embryonic/organogenesis which could lead to defects in the fetus because some types of drugs can penetrate the placenta and will undergo biotransformation into a highly reactive compound that has the potential to become a teratogenic compound. The aim of this research was to examine the teratogenic effect of bintangur leaves (Calophyllum soulattri Burm. F) ethanol extract to Sprague Dawley strain white rats. Methods: The white rats are divided into four treatment groups: Control group was given carboxymethyl cellulose Na 1%, comparison group was given trimethoprim 360 mg/kg BW, C. soulattri leaves ethanol extract (CLE) 100 mg/kg BW, and CLE 500 mg/kg BW. The treatment was administrated since organogenesis period. Cesarian section was performed to pregnant rat at the 20th day to separate the fetuses. Observation covered body weight of pregnant rats, fetal biometric, morphological malformation, and skeletal formation. Results: CLE 100 mg/kg BW and 500 mg/kg BW did not cause any change in the number of a living fetus, body weight, and length of fetuses like the comparison group. Both doses of CLE shown have a normal skeletal formation. Resorption was found in the comparison group and CLE 100 mg/kg BW with the percentage was 65.21% and 6.67%. It was found that there is no significant difference (p<0.05) between both doses of CLE compared to control group. Conclusion: From the results, it is concluded that CLE did not have the teratogenic effect.

Sidaguri leaves (Sida rhombifolia L.) Have been shown to contain flavonoid compounds, where they are efficacious as hyperuricemia. This study aims to determine effectiveness ethanol extract of sidaguri leaves as antihyperuricemia in white rats. The study was conducted using the method of potassium oxanate induction and measured using glucometers. 15 animals were divided into 5 groups, namely negative control, positive control, group I combination of ethanol extract of sidaguri leaves 50 mg / kg body weight, group II ethanol extract of sidaguri leaves 100 mg / kg body weight, group III ethanol extract of sidaguri leaves 200 mg / kg body weight for 5 hours. Examination of antihyperuricemia effects is done by comparing the uric acid levels value of the rats before and after treatment. The results of this study indicate that the three dose ethanol extract of sidaguri leaves provide an antihyperuricemia effect and based on one-way Anova, Tuckey and LSD data analysis, shows that the dose of 50 mg / kg body weight is effective as antihyperuricemia and does not have a significant difference (p> 0.05). The conclusion of this study is that the dose is the most effective in decreases uric acid levels in white rats, which is a dose of 200 mg / kg body weight because it mostly decreased uric acid levels.

Background: Preeclampsia is a disease with a variety of theories that describe the uncertainty of the pathophysiology. According to the oxidative stress theory, preeclampsia originates from the failure of trophoblast invasion during the implantation process, causing ischemia and placental hypoxia, which in turn causes cell damage, including placental endothelial cell dysfunction. Omega-3 fatty acids and vitamin E have an important role in preventing preeclampsia. Omega-3 fatty acids play an important role in maintaining cell membranes and anti-inflammatory processes. At the same time, vitamin E acts as a fat-soluble antioxidant that can prevent oxidative stress, inhibit proinflammatory cytokines, and protect fatty acids from oxidation. Aim: The purpose of this study was to determine the effect of omega-3 and vitamin E on the level of ROS and NO in pregnant rats with preeclampsia models. Method & Material: This type of research is experimental with Post-Test Only Control Group Design. The sample consisted of 35 pregnant rats, which were divided into five groups. On the 19th day, blood serum was taken to check the levels of ROS and NO. The measuring instrument used is a spectrophotometer with the ELISA method. Data were analyzed using the Shapiro Wilks normality test. After the parametric test was completed, the hypothesis was tested using one-way ANOVA. Results: The average levels of ROS in each group were K- : 121,684 ng/L, K+ : 143,885 ng/L, P1 : 136,250 ng/L, P2 : 132.433 ng/L, and P3 : 122,993 ng/L. The average levels of NO obtained were K-: 29,502 ng/L, K+: 26,053 ng/L, P1: 27,250 ng/L, P2: 27,555 ng/L, and P3: 32,278 ng/L. The results of one-way ANOVA analysis showed that the administration of omega-3 and vitamin E had a significant difference between the control and treatment groups, both at levels of ROS (p=0.001) and levels of NO (p=0.001). Conclusion: The administration of omega-3, vitamin E, and omega-3 plus vitamin E can reduce ROS levels in pregnant rats with preeclampsia models. There is an increase of NO levels only in the administration of omega-3 plus vitamin E. Keywords: [Omega-3, Vitamin E, Oxidative stress, ROS, NO, Preeclampsia].

Endosulfan an organochlorine insecticide that is commonly used even though it has been banned due to its toxic and teratogenic effect. This study aims to determine the effect of orally endosulfan exposure to pregnant rat (Rattus norvegicus) at day 6-15th of gestation period to the foetus skeletal malformation. A Completely Randomized Design (CRD) by endosulfan dosages: 0 (control); 0.083; 0.190; 0.440; 1.000 mg/kg BW/day with 5 replicates was applied. At 20th of the gestational period, the rats were sacrificed, their reproductive organs and the fetal skeletal malformation were observed using Alizarin red S method. The results of one-way ANOVA test showed that endosulfan exposure did not significantly affect the pregnancy outcomes ie. female rats weight gain, the numbers of implanted foetus, foetal body weight and length, respectively. Malformation of foetus implantation, foetus size and foetus skeletal occured in the endosulfan exposure groups. Fisher’s exact test results showed a significant difference between the control group and the endosulfan exposure group on the number of foetuses that have abnormalities in the number of skeletons of the sternum, fore and hind paws. The exposure of endosulfan at 0.083-1.000 mg / kg BW / day in pregnant rats caused skeletal malformations of the foetus ie. decreased in the number on sternum, fore- and hind paw bones. ABSTRAK Endosulfan merupakan insektisida golongan organoklorin yang masih digunakan hingga kini meski telah dilarang karena bersifat toksik dan teratogenik. Penelitian ini bertujuan untuk mengetahui efek pemajanan endosulfan secara oral terhadap malformasi rangka fetus tikus (Rattus norvegicus Berkenhout, 1769) selama umur kebuntingan 6-15 hari. Penelitian dilakukan secara eksperimental di laboratorium menggunakan Rancangan Acak Lengkap (RAL) dengan pemajanan endosulfan dosis: 0 (kontrol); 0,083; 0,19; 0,44; dan 1 mg/kg BB/hari dan masing-masing diulang sebanyak lima kali. Induk betina dengan umur kebuntingan 20 hari, dikorbankan nyawanya lalu dibedah dan diamati tampilan reproduksi induk serta malformasi rangka pada fetus dengan metode pewarnaan Alizarin red S. Hasil uji sidik ragam satu arah menunjukkan pemajanan endosulfan tidak berpengaruh secara signifikan terhadap rataan pertambahan bobot badan induk, jumlah fetus terimplantasi, bobot badan dan panjang fetus. Malformasi implantasi fetus, ukuran fetus dan rangka fetus terjadi pada kelompok pemajanan endosulfan. Hasil uji eksak Fisher menunjukkan adanya perbedaan yang signifikan antara kelompok kontrol dengan kelompok pemajanan endosulfan terhadap jumlah fetus yang mengalami kelainan jumlah rangka penyusun sternum, cakar depan dan cakar belakang. Simpulan dari penelitian ini adalah pemajanan endosulfan dosis 0,083- 1,000 mg/kg BB/hari pada tikus bunting menimbulkan malformasi rangka pada fetus yaitu berkurangnya jumlah tulang penyusun sternum, cakar depan, dan cakar belakang.

Objective: Sertoli cell and spermatogonia are formed in the prenatal period, and alterations information process could affect the reproduction function in the adolescence and adult period. This study aimed to unveil the effect of tempeh’s isoflavone that was given from prenatal to weaning during childhood period toward the amount of Sertoli cell and spermatogonia.Method: The study design was randomized post-test only control group design with 15 female Wistar experimental mouse in the aged of 12th– 13th weeks was used and divided into three groups, namely, control groups (C) that were given aquadest, intervention Group 1 (I1) and intervention Group 2 (I2) that was given tempeh 0.5 g/kg body weight/day ethanol extract that contains 0.52 mg genistein and 5 g/kg body weight/day that contains 5.2 mg genistein, respectively. The intervention was given for a week before copulation, during pregnancy and lactation period. The observed parameters were Sertoli cell and spermatogonia of an early-born mouse.Result: The amount of Sertoli cell and spermatogonia were different between the three groups (p<0.05). The I2 group has the lowest amount of Sertoli cell and spermatogonia and shows a significant difference from the control group as well as I1 (p<0.05). Tempeh ethanol extract has a direct impact on reducing the amount of Sertoli cell to about 11% lower than control. It also affected the number of spermatogonia indirectly through its effect toward Sertoli cells.Conclusion: Intervention of tempeh ethanol extract to female Wistar experimental mouse from prenatal period to weaning child period could disturb the formation of Sertoli cell and spermatogonia of the early-born mouse.
