PURPOSE: To evaluate the effect of soluble fiber or fructooligosaccharide (FOS) supplementation upon trinitrobenzene sulphonic acid (TNBS)-induced colitis in rats. METHODS: 64 Wistar rats were given water, soluble fiber or FOS intragastrically during 14 days prior to colitis induction with TNBS (n=48) or rectal enema with water (n=16; control group). On the 7th or 14th day following colitis induction the rats were weighed and euthanized in order to determine the colon weight/length ratio and macroscopic and microscopic scores. RESULTS: On the 7th day following colitis induction the body weight had decreased significantly, the colon weight/length ratio had increased and macroscopic and microscopic colon lesions were observed. On the 14th day following colitis induction no difference in body weight was observed, in spite of the persistence of macroscopic and microscopic lesions and increased colon weight/length ratio. Supplementation with soluble fiber or FOS did not revert colon lesions or any of the study parameters. Supplementation with FOS, but not with fiber, was associated with increased colon weight/length ratio on the 14th day. CONCLUSION: Supplementation with soluble fiber or FOS produced no significant impact on TNBS-induced colitis in rats.

The aim of this study was to evaluate the influence of ligature-induced periodontal disease in pregnant rats on their newborn's health parameters. Twenty-four female adult Wistar rats were divided into two groups: the control group (G1) and the group that was submitted to dental ligatures around second upper molars (G2). After the four week period of development of periodontitis, the female animals were mated with male adult Wistar rats. There were no differences in the body weight of females between the two groups during mating and pregnancy. No differences were observed among the groups in relation to the viable newborn index. However, there were differences in newborn birth weight, explained by the diverse size of the litters. In this study, ligature-induced periodontal disease did not promote changes during pregnancy that resulted in low birth weight in newborn Wistar rats.

AbstrakPepaya mengandung pektin yang merupakan serat larut air. Pektin berkemampuan mengikat asam empedu dan dieliminasi keluar tubuh melalui feses. Penurunan jumlah asam empedu di lumen usus menyebabkan hepar menggunakan kolesterol dalam darah untuk membentuk asam empedu. Hal tersebut mengakibatkan penurunan jumlah kolesterol.Tujuan studi ini adalah untuk melihat pengaruh pemberian ekstrak pepaya mengkal terhadap kadar kolesterol total, HDL dan LDL tikus putih. Desain penelitian ini adalah eksperimental menggunakan 20 ekor tikus putih jantan yang dibagi menjadi empat kelompok, yaitu kelompok kontrol, dan kelompok perlakuan dengan pemberian ekstrak pepaya dengan dosis 0,5 ml, 1 ml dan 1,5 ml per 200g/BB melalui oral selama 15 hari.Hasil penelitian menunjukkan terjadinya penurunan rerata kadar kolesterol total, LDL, dan peningkatan kadar HDL serum tikus setelah pemberian ekstrak pepaya selama 15 hari secara bermakna (p<0,05). Tetapi tidak terjadi perbedaan yang bermakna (p>0,05) antara kelompok yang diberi ekstrak pepaya dengan dosis 0,5 ml, 1 ml, dan 1,5 ml.Kesimpulan yang dapat diambil dari studi ini ialah bahwa ekstrak pepaya dapat menurunkan kadar kolesterol total, LDL, dan peningkatan kadar HDL pada serum tikus putih jantanKata kunci : pektin, kolesterol, asam empedu, serat, tikus.AbstractPapaya contain pectin which is a water-soluble fiber. Pectin has the ablity to bind bile acids and eliminated out of the body through the feces. Decrease in the amount of bile acids in intestinal lumen causing liver uses cholesterol to synthesize bile acids blood.The purpose of this study was to see the effect of papaya extract on total cholesterol, HDL and LDL of male rats.

This study aims to determine the effects of open and closed formulated standard diets supplied from different sources on growth performance and internal organ development of laboratory rats. Five-week-old 32 Wistar rats were used. A special control group diet was produced in accordance with the criteria determined by the National Research Council (NRC) (1995). Three different most preferred commercial open and closed-formula diets produced by international and local companies were used as trial groups’ diets. The experiment was carried out for 12 weeks. Weekly feed consumption, body weight change, internal organ weight, intestinal organ weigths and lengths, intestinal villi heigth and crypt depth were measured in groups. The body weight values of the control group and the first group fed with open-formula diet were found at the highest level (P <0.05). The control group diet had a positive effect on small intestine villi heigth and crypt depth (P <0.05). The nutrient contents and energy values of the diets of experimental groups were determined as different from the commercial firm notifications. As a result of the research, it is concluded that the diets prepared with open-formula give more reliable results in the growth performance and development of internal organs of Wistar rats.

To assess the effect of methanolic leaf extract of Caladium bicolor on the histomorphology of gastrointestinal tissues of experimental animals. Twenty four Wistar rats (weighing between 175-190 g) were randomly and equally divided into four groups which include one control group (CG) and three treatment groups (TG I, TG II and TG III). The CG was administered with distilled water [2 ml/kg body weight (b.w.)] while TGs I, II and III were administered with 100 ml/kg, 200 ml/kg and 300 ml/kg (b.w.) of C. bicolor extract respectively. All administrations were done orally and once daily for a period of thirty days. The body weight of all animals was recorded at the beginning and end of study. After the period of study, gastric and small intestinal tissues of experimental animals were harvested, processed, converted to tissue blocks and sectioned. Tissue sections were stained using Haematoxylin and Eosin (H&E) technique. Thereafter, stained sections microscopically examined for observable histopathological changes within study tissues. The results of this study showed that exposure to C. bicolor extract causes significant (p < 0.05) body weight loss in TGs I-III compared to CG. In addition, prominent histopathological changes were observed in gastrointestinal tissues of experimental animals in TGs I-III including gastric mucosal surface erosion and intestinal villi degeneration compared to normal gastrointestinal histomorphology of CG animals. These histopathological changes may be associated with toxic effect of phytochemicals constituents of the extract. Therefore, its application for therapeutic purposes needs to be thoroughly re-validated or perhaps disallowed where alternative therapeutic agents with minimal toxic potential exist.

Physiological stress for a long time can lead to impaired kidney organ function. Snakehead fish meat are known to contain important nutrients such as albumin, glutamine, glycine, cysteine, and various minerals that can improve kidney function. This study was conducted to examine and analyze the effect of snakehead fish supplementation in feed towards body weight, kidney weight, diameter and number of glomerulus in Wistar rats with physiological stress. This study used 20 male Wistar rats divided into 5 groups consisted of 1 control group (P0) and 4 treatment groups (P1: 5%, P2: 10%, P3: 15%, P4: 20%). The treatments were performed with 4 times repetition. This study used Completely Randomized Design (CRD). The variables measured were body weight, kidney weight, diameter and number of renal glomerulus. The data obtained were analyzed using Analysis of Variance (ANOVA) at 5% significance level and continued with Duncan test with 5% significance level. The results of this study were: the supplementation of snakehead fish with 20% of concentration can increase the body weight; concentration 10; 15; and 20% can increase the weight of the kidney; concentrations of 5%, 10%, 15%, and 20% can increase the glomerular diameter in Wistar rats with physiological stress. The supplementation of snakehead fish with concentration of 5% to 20% did not affect the number of glomerulus of Wistar rats with physiological stress. Results of this study is useful as information for people who study the mechanism of kidney repair due to physiological stress.

We studied lungs of spontaneously diabetic Bio-Breeding/Worcester (BB/W) Wistar rats which resemble human insulin-dependent diabetes mellitus. Compared with the age-matched control group, the body weight of the diabetic rats tended to be smaller and lung wet and dry weight were similar, but lung dry weight, relative to body weight and to lung wet weight, was significantly larger. Both air and saline lung volumes were reduced in the diabetic rats, and volume-pressure (V-P) curves expressed as a percent of maximal lung volume were significantly shifted downward and to the right of those in the control group over the midportion. Total DNA and RNA contents were similar in both groups, whereas protein content and concentration and protein/DNA and RNA/DNA ratios were significantly reduced in the diabetic rats. In contrast, content and concentration of 4-hydroxy-L-proline, elastin, and crude connective tissue were significantly higher in the diabetic group. We conclude that the increase in connective tissue proteins in the BB/W rats is most likely responsible for the shift in the V-P curves.

Цель - морфофункциональная характеристика нарушений функции печени при алиментарном ожирении и их коррекция мелатонином. Методы. В эксперименте использовано 3 группы половозрелых (2 мес.) крыс-самок Wistar с исходной массой 180-200 г. 1-я группа - контроль (интактные крысы); 2-я - группа «ожирение» (модель алиментарного ожирения воспроизводилась путем добавления (без ограничения) к стандартному лабораторному рациону в течение 3 мес. пищевых жиров животного происхождения) и 3-я группа («ожирение + мелатонин») - животные с алиментарным ожирением, которым в течение 14 сут. per os через желудочный зонд 1 раз в сут. вводили водный раствор мелатонина (0,1 г на 100 г массы тела), животные жиры из рациона во время введения препарата не исключались. Крыс декапитировали под этаминаловым наркозом (40 мг на кг), извлекали печень для морфометрического и светооптического исследования (микроскоп LEICA DM 750, камера LEICA ICC 50 HD). Патогистологические препараты готовили по общепринятой методике. Исследование препаратов печени проводили при увеличении х1000 на срезах толщиной 5 мкм, окрашенных гематоксилином Майера и эозином, сульфатом нильского голубого. Для морфометрического анализа использовали метод наложения точечных морфометрических сеток (сетка 256 точек). Определяли относительную площадь сети синусоидов, ядер и цитоплазмы гепатоцитов, численную плотность синусоидных клеток и гепатоцитов и двуядерных паренхиматозных клеток; рассчитывали ядерно-цитоплазматическое соотношение, отношение численной плотности синусоидных клеток к численной плотности всех гепатоцитов, вычисляли долю диплокариоцитов от общего числа гепатоцитов, рассчитывали коэффициент Vizotto - отношение площади сети синусоидов к площади всех гепатоцитов. Результаты. Введение мелатонина нивелировало признаки нарушения кровообращения, крово- и лимфотока. Отмечалась сохранность сосудов портального тракта, восстановление архитектоники центральных вен. Большинство участков гемо- и лимфообращения не имело признаков грубых нарушений. Заключение. Ожирение приводит к значительным нарушениям в системе кровообращения и лимфотока в печени, развитию жировой дистрофии. Введение таким животным гормона эпифиза мелатонина способствует усилению репаративных процессов в печени, нормализации микроциркуляторных процессов, восстановлению микроструктурной и функциональной организации органа. Aim. To identify and assess morpho-functional changes in the liver of Wistar rats on a model of alimentary obesity and correct the changes with the pineal hormone, melatonin, a universal adaptogen, immune modulator, and potent antioxidant. Methods. Sexually mature female Wistar rats aged 2 months and weighing 180-200 g at baseline were used for the experiment. Rats were allocated to three groups, 1) control group (intact rats); 2) group with alimentary obesity modeled by adding animal fat to the ad libitum standard laboratory diet for 3 months (obesity group); and 3) obesity group treated with melatonin 0.1 g/100 g body weight in 200 µl of distilled water, orally through a gastric tube, once daily for 14 days; during the treatment, animal fat was not excluded from the diet (obesity + melatonin group). Rats were sacrificed under etaminal anesthesia (40 mg/kg body weight) by decapitation. For morphometric and optical studies (LEICA DM 750 microscope, LEICA ICC 50 HD camera), histopathological preparations were fixed in 10% buffered formalin and examined with a standard method. Morphometric studies of liver samples were performed at a x1000 magnification on 5 µm sections stained with Mayer’s hematoxylin and eosin stain and Nile blue sulfate using superposition of point morphometric grids (grid of 256 points). Relative areas of sinusoid network, hepatocyte nuclei and cytoplasm; numerical density of sinusoidal cells, hepatocytes, and dual-parenchymal cells were measured. The nuclear-cytoplasmic ratio; ratio of sinusoidal cell numerical density to the numerical density of all hepatocytes; and per cent of diplocaryocytes of the total number of hepatocytes were computed; the Vizotto coefficient was calculated as a ratio of the area of sinusoid network to the area of all parenchymal hepatocytes. Results. Administration of the animal hormone, melatonin, exerted a pronounced effect on the studied morphometric parameters and reversed signs of circulatory and lymph flow disorders. Blood vessels of the portal area were preserved, and the architectonics of central veins was recovered. Most parts of hemo- and lymph circulation had no abnormal features. Conclusion. Obesity leads to significant disorders of blood circulation and lymph flow in the liver and results in fatty degeneration of hepatic parenchyma. Administration of the pineal hormone, melatonin, to such animals enhances reparative processes in the liver, normalizes microcirculation, and restores the structural and functional organization of the body.

Backgound: Non Alcoholic Fatty Liver Disease (NAFLD) occurs when the intake and free fatty acid synthesis occurs more frequently than its oxidation and resecretion in the blood. Melatonin is a powerful antioxidant that can boost the synthesis of endogenous antioxidants in the body, suppress the inflammatory response and inhibit the formation of steatosis.Objective: To analyze the effect of melatonin supplementation in reducing body weight andTNF-α levels in male Wistar rats were fed by waste cooking oil.Methods: True experimental studyusing post-test only control group design. This study was done on 18 male wistar rats were divided into 3 groups : the positive control group (P0) was administrated waste cooking oil, the treated group 1 (P1) was administrated waste cooking oil and 5mg/kgBW melatonin, and the treated group 2 (P2) was administrated waste cooking oil and 10mg/kgBW melatonin for 28 days.Data analysis using One Way ANOVA test and followed by Tukey test to determine the most effective dose of melatonin.Results: There was significant difference in body weightbetween P2group and K0 group (p=0,019) with the mean body weight difference was 19,167g lower than K0 group. There was no difference in TNF-α levels between the three groups (p=0,155). Conclusion: Melatonin dose of 10mg/kgBWloses body weight male Wistar rats have given by waste cooking oil for 28 days, but does not reduce TNF-α levels.

The present study was aimed at investigating the safety of Lacidipine (LCDP) loaded nanostructured lipid carriers (NLCs) in Wistar rats. NLCs were formulated using ultrasound dispersion technique. Animals were orally treated once daily with NLCs containing 0.140 mg, 0.350 mg, and 0.875 mg of LCDP as low, medium, and high dose per kg body weight, respectively, during 28 days along with blank formulation and pure LCDP. Control rats were fed with water. Animals were observed throughout experiment period and their body weight was recorded once weekly. Overnight fasted rats were sacrificed on the 29th day. Study revealed no signs or symptoms of toxicity or morbidity. No significant changes in the body weight were observed between treated and control group. Significant increase in left testis weight and liver weight was observed in male and female rats, respectively. Haematological estimation revealed significant decrease in haemoglobin count in male rats while female rats showed significant increase in granulocyte count. All the serum clinical parameters were within the normal range and no gross histopathological changes were observed. No delayed effect was noted in satellite group. The results indicate that developed LCDP loaded NLCs are safe when administered orally in rats.
