ABSTRAKKanker usus besar merupakan kanker yang memiliki insiden dan mortalitas tinggi. Karsinogenesis ditandai oleh proliferasi sel yang tidak terkendali, yang dapat dilihat dengan adanya peningkatan ekspresi Ki67. Kejadian kanker usus besar meningkat akhir-akhir ini yang dimungkinkan terjadi akibat pola makan masyarakat modern yang buruk. Masyarakat modern lebih menyukai makanan cepat saji, yang rendah serat dibandingkan makanan sehat yang kaya serat, seperti ganyong. Penelitian ini bertujuan untuk mengkaji efek pemberian ganyong terhadap ekspresi Ki67 pada jaringan usus besar tikus yang diinduksi AOM/DSS. Jenis penelitian ini merupakan eksperimental dengan post test only group design. Penelitian ini menggunakan tikus model kanker usus besar yang dibuat dengan induksi AOM/DSS. Perlakuan ganyong diberikan selama 16 minggu, diberikan mulai 2 minggu sebelum induksi AOM hingga sebelum terminasi. Ekspresi ki67 dilihat dengan metode imunohistokimia, kemudian dihitung menggunakan software Image J.

Kesimpulannya bahwa pemberian ganyong pada tikus yang diinduksi AOM/DSS tidak menghambat proliferasi sel.Kata Kunci: Ganyong, Ki67, Induksi Aom/Dss. ABSTRACTColon cancer is a cancer that has a high incidence and mortality. Carcinogenesis is characterized by uncontrolled cell proliferation, which can be seen in the presence of increased Ki67 expression. The incidence of colon cancer has increased in recent years, which may have been due to the poor diet of modern society. Modern society prefers fast food, which is low in fiber compared to healthy foods rich in fiber, such as ganyong. This study aims to examine the effect of canna administration on Ki67 expression in AOM / DSS-induced rectum colon tissue. This research type is experimental with post test only group design. This study used a mouse model of colon cancer made with AOM / DSS induction. Canna administration was given for 16 weeks, given 2 weeks before AOM induction until termination. Ki67 expression seen with imunohistokimia method, then calculated using Image J software. The results showed that canna administration did not decrease of Ki67 expression in rats induced AOM / DSS (p = 0,101). In conclusion that canna administration to rats induced by AOM / DSS did not inhibit cell proliferation.Keywords: Canna, Ki67, AOM / DSS Induction.

Calcium is one of the most important minerals needed during hard tissue development. The preparation of this material into nano-sized particle is carried out to enhance the bioavailability and distribution of calcium in the body. Lack of calcium during odontogenesis causes defect in enamel such as hypoplasia and hypomineralization. During amelogenesis, after secretion of organic matrices, enamel mineralization will start in the presence of calcium. The objective of this study was to determine the effect of nano calcium supplementation during pregnancy on enamel development. In this study, 3-month-old female Sprague Dawley were mated and divided into three groups: nano calcium group (A), micro calcium group (B), and negative control group (C). The treatment was started on day 1 of pregnancy to day 1 after birth by intragastric administration method. The mandibles of 6 pups from each group were collected and stained with hematoxylin and eosin. Examination was conducted using microscope. Enamel deposition was measured using Optilab Image Raster® and the data collected was analyzed using t-test. Histological section of mandibular right first molar on Sprague Dawley newborn pups showed that enamel was observed on day 1 after birth but only on the group treated with nano calcium and micro calcium. Statistical analysis performed showed that the difference between the two groups was significant (p<0.05). From this study it can be concluded that the administration of nano calcium during pregnancy leads to rapid enamel deposition on Sprague Dawley pups.

Diabetic patients suffer inflammation and immune deficiency as a consequence of the decrease in macrophage phagocytic activity, thus making them vulnerable to infection. The ability of Ethanolic Extract of Phaleria macrocarpa Leaf (EEPML) to increase macrophage phagocytic activity has also a potential in the diabetic case. EEPML also has anti-inflammatory effect. In this study the EEPML potential to increase peritoneal macrophage phagocytic activity and change M1 and M2 macrophage percentage in diabetic rat model is investigated. This was a quasi experimental study with post test only control group design. Fourty five male Sprague Dawley rats within the age of 8 weeks were classified into normal control group, diabetic control group with solvent, diabetic with 7mg/200g, 14mg/200g, and 28mg/200g of EEPML peroral administration, once a day. The diabetic rat model was made with streptozotocin and nicotinamide injection. The rats were terminated in 3rd, 14th and 25th day of extract administration. Peritoneal fluid was isolated then cultured for macrophage phagocytic activity assay with latex beads. M1 and M2 macrophage percentage was analyzed using flow cytometry with anti CD40 and CD206 antibody. Result of statistical analysis show that active macrophage and phagocytic index mean of EEPML rat groups on day 3, 14 and 25 was significantly higher than the control group. The mean of M1 macrophage percentage of EEPML rat groups was significantly higher than control on day 3 and 14, and lower on day 25, while mean of M2 macrophage percentage didn’t show any significant difference within groups. Conclusion of this study is administration of EEPML increases peritoneal macrophage phagocytic activity on day 3, 14 and 25. This is also increases M1 macrophage percentage on day 14, decrease M1 macrophage percentage on day 25, and doesn’t change peritoneal M2 macrophage percentage in diabetic rat model.

Aspirin or ethanol induced gastric ulcer rat models are the most frequently used in studies.Aspirin and ethanol induced gastric ulcers through different pathways involving COX-2 andiNOS. The aim of this study was to examine the expression of COX-2 and iNOS in gastriculcer rat model induced by ethanol and aspirin. Twenty-one Sprague Dawley rats weredivided into 7 groups i.e. control group (CA), ethanol 1st day (ED1), ethanol 3rd day (ED3),ethanol 5th day (ED5), aspirin 4th day (AD4), aspirin 6th day (AD6), and aspirin 8th day (AD8).Oral administration of aspirin was at 200mg/kgBW and the 100% ethanol at 1mL/200gBW.Macroscopic and microscopic observations were done to examine the gastric mucosaldamage, COX-2 and iNOS expressions. Severe gastric ulcers were observed in ED1and AD4 groups and mild gastric mucosal damage was observed in ED3, ED5, AD6 andAD8 groups. Microscopically, light erosion was shown by the CA and AD8 groups. Erosionwas also shown by ED3, ED5, and AD6 groups. The most severe damage with ulcers andheavier bleeding were shown by the ED1 and AD4 groups. Weak COX-2 expression wasfound in the CA, while the highest COX-2 expression was found in the ED1. The iNOSexpression in the ethanol groups was still increasing until the 5th day (ED5). In the aspiringroups, it reached the peak on the 3rd day (AD6), and already declined on the 5th day (AD8).In conclusion, the damage process of ethanol induced gastric ulcer occurred faster thanthat by aspirin. The highest COX-2 expression in the ethanol and aspirin groups wereshown at the onset begin. iNOS expression in ethanol induced ulcer groups still increaseduntil the 5th day, while in the aspirin induced ulcer groups already declined in the 5th day.

Background: Due to the content of lectures for nutrient handling often delivered from one scientific discipline, students do not gain a comprehensive understanding. The flipped classroom learning approach helps improve students' overall comprehension by integrating multiple scientific disciplines such as physiology, anatomy, biochemistry, and histology.Aims: The purpose of this study is to assess the efficacy of the flipped classroom learning approach in nutrition management lectures that incorporate physiology, anatomy, biochemistry, and histology.Methods: A basic pre-post test design was employed in this research. The flipped classroom method was used by first asking students to learn the topic via instructional videos, lecture files, and a pre-test (58 questions) on the eLOK UGM platform. The panel discussion was then carried out by lectures from four departments, including physiology, anatomy, biochemistry, and histology, via the Zoom platform (virtual synchronous learning). Finally, students were required to do a post-test with the same content as the pre-test.Results: According to the findings of this study, the average pre-test score of college participants was less than 80, whereas the average post-test score was 84.22, with 73.20% of the participants scoring higher than 80. The integrated panel discussion affected male participants' N-Gain scores. Male participants scored 0.74 (high category) while female participants scored 0.69 (medium category). Conclusions: The flipped classroom method can support approaches from departments of anatomy, physiology, histology, and biochemistry - in a relatively time-efficient but more effective means of improving understanding of nutrient handling.
