Sclerotherapy is the chemical occlusion of vessels using an intravenous injection of a liquid or foamed sclerosing agent that is used in the therapy of blood and lymphatic vessels malformations in the young, and for spider veins, smaller varicose veins, hemorrhoids and hydroceles in adults. This study aimed to assess the effectiveness of mechanosclerotherapy of venous veins with a new device—Flebogrif®—based on an animal model. The experiment was performed on nine Polish Merino sheep weighing 40–50 kilograms. The animals were anesthetized intravenously. The material was divided into three groups: two experimental (1 and 2) and control (3) group. The first experimental group was treated with the use of Flebogrif® and a sclerosant simultaneously, while only Flebogrif® was used in the second experimental group. Flebogrif® was applied into the lateral saphenous vein of both pelvic limbs. The vessel wall thickness was estimated at four points of the histological image in mm (V1, V2, V3, V4). For one month, the animals were euthanized, and the occlusion rate of the treated veins and changes in the vein wall were determined. Histological slides were analyzed under a light microscope and histometry of the vein wall was performed. The Shapiro–Wilk test and the quantity of the investigated parameter groups allowed for using a non-parametric method at four points to compare thickness measurements (the Mann–Whitney test), with p < 0.05. The Mann–Whitney test indicated statistically significant differences between both experimental groups. The results obtained from morphometrical and histological analysis showed better results in the first experimental group than those of the second experimental group. Finally, statistical analysis revealed significant differences between the both the experimental group and control group in morphological analysis. The achieved results allowed us to conclude that the simultaneous use of Flebogrif® and a sclerosant yielded better results of vein lumen reduction than the use of Flebogrif® alone.

Background: The prolonged partus is one of the causes of maternal deaths marked by the slow progress of labor. Induction of labor and caesarean section is a common procedure performed on long-term partus events to end pregnancy. The birth acupressure technique is a complementary method to activate the hormone oxytocin at a certain point to use to soften the cervix and increase contraction.Objective: To examine the effect of acupressure point LI4, SP6 and BL60 on the duration of the first stage of labor and APGAR Score of newborn in primigravida.Methods: This research employed a Quasy experimental study with posttest control group design. It was conducted at the Public Health Center of Trauma and Public Health Center of Palaran Samarinda, East Kalimantan. There were 40 respondents selected using purposive sampling, which 20 respondents assigned in the experiment and control group. The duration of the first stage of labor was assessed using partograph and APGAR Score was assessed using APGAR Score assessment sheets. Mann Whitney test was used for data analysisResults: Findings showed that the duration of the first stage of labor in the experiment group was 187 minutes and in the control group was 307 minutes. Mann Whitney test obtained p-value 0.001 (<0.05), which indicated that there was a statistically significant difference of the duration of the first stage of labor between both groups. However, Mann Whitney test for APGAR score showed p-value 0.114 (>0.05), which indicated that there was no significant difference of APGAR score in the experiment and control group.Conclusion: There was a significant effect of acupressure on the duration of the first stage of labor, but no effect of the APGAR score. Therefore, acupressure may be recommended to shorten the duration of the first stage of delivery in primigravida.

Intelligence for young children is very important for themselves and their social development, because if the intelligence of children develops well, it will be easier for them to get along with creating new things. Besides learning media has a very important role in the learning process. Media that can improve mathematical logical intelligence in children, one of them is the dice numbers. Based on observations shows that the logical-mathematical intelligence of students is still low. This study uses a quasi-experimental method using a non-equivalent control group design. Based on the calculation of the experimental class normality test that is 0.044 <0.05, so the data are declared not normally distributed. While in the control class the result is 0.200> 0.05, until the data are declared normally distributed. Therefore, because one class is declared not normally distributed, the data will be processed using the Mann Whitney test. The results of the Mann Whitney test in the experimental and control classes were 0.001 <0.05. So the conclusion is dice media can improve mathematical logical intelligence.Kecerdasan untuk anak usia dini sangat berperan penting bagi dirinya maupun perkembangan sosialnya, karena jika kecerdasan anak berkembang dengan baik maka akan memudahkan mereka bergaul juga menciptakan hal-hal baru. Selain itu media pembelajaran memiliki peranan sangat penting pada  proses belajar. Media yang dapat meningkatkan kecerdasan logis matematis pada anak, salah satunya yaitu dadu angka. Berdasarkan hasil observasi, kecerdasan logis-matematis peserta didik masih tergolong rendah. Penelitian ini memakai metode kuasi eksperimen serta memakai desain kelompok kontrol non-ekuivalen (the nonequivalent control group design). Berdasarkan perhitungan uji normalitas kelas eksperimen yakni 0.044 < 0.05, sehingga data dinyatakan tidak berdistribusi normal. Sedangkan di kelas kontrol hasilnya adalah 0.200 > 0.05, hingga data dinyatakan berdistribusi normal. Oleh sebab itu karena salah satu kelas dinyatakan tidak berdistribusi normal, data akan diolah memakai uji Mann Whitney. Hasil dari postes Mann whitney di kelas eksperimen serta kontrol adalah 0.001 <  0.05. Jadi kesimpulannya media dadu angka dapat meningkatkan kecerdasan logis matematis.
