ABSTRACT Excessive energi consumption of high-fat diet increase the body’s adipose tissue which also affect the increased secretion of leptin, this is because leptin secretion is proportional to the mass of adipose tissue. Leptin activates the lateral hypothalamus as the center of hunger and feeding activity. The aim of this study was to obtain the relationship between high trans fat feeding on male Wistar rats and feeding activity. This method uses male Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% trans fat, the second group was given additional feed 40% trans fat, a third group was given additional feed 60% trans fat, and the last as a control group. This feed was given once a day for 70 days. Observation of activities perform using Opto-varimex® auto-track system ver. 4.31. The results showed an corellation between activity based doses of trans fat. Keywords: Opto-varimex®, Trans fat, Activity, Wistar rat.

Excessive energi consumption play a role in increasing blood glucose levels (hyperglycemia), due to the inability of the hormone insulin to compensate the high blood glucose levels. Blood glucose receptor found in the hypothalamus of VMH (Ventro Medial Hypothalamus) and LH (the Lateral Hypothalamus) is able to detect and change the settings for the feeding activity. The aim of this study was to obtain the relationship between high sucrose feeding on male Wistar rats of behavior and activity. This method uses Wistar rats (Rattus norvegicus) as an animal model. Sixteen rats were grouped into 4 treatment groups. The first group was given additional feed 20% sucrose, the second group was given additional feed 40% sucrose, a third group was given additional feed 60% sucrose, and the last as a control group. This feed given continuously for 70 days.Observation of activities conducted using Opto-varimex® auto-track system ver.4.31. The results showed an corellation between activity based doses of sucrose.

This study aims to look at the histopathological picture of the dorsal arteries of the penis of the hiperlipidemic wistar rats (Rattus novergicus) induction by high-fat diet that seen in terms of lumen diameter and thickness of the arterial endotelium wall. Hyperlipidemia is a risk factor for ateriosclerosis in the penile arteries causing erectile dysfunction in men. This study is an experimental study with a randomized posttest only control goup design. The sample are  10 individuals adult male wistar rats aged 3-4 months with a range of body weight 150-200 grams. Before treatment, adaptation was carried out for 7 days. After that the sample rats in the treatment group were made hyperlidemic by feeding lard for 50 days. Then surgery is performed for histopathological preparations at the posttest. To determine the differences in endotelium thickness and arterial lumen diameter in the two groups, an independent t-test was used. Thick diameter data of the endotelium and dorsal arteries of the penis of the wistar rat between the lower treatment group and the control group. The difference that occurred was statistically significant (p <0.05). So it can be concluded that the provision of high-fat diet (hyperlipidemia) decreases the lumen diameter and endotelium thickness of dorsal arteries penis.

Background: There is a folk belief that drinking Ramsar spring mineral water (RSW) is a remedy for renal stones. Objectives: This study aimed to evaluate the effect of RSW on prevention or treatment of nephrolithiasis in male Wistar rats and identify the constituents of the water. Methods: Nephrolithiasis was induced by providing drinking water containing 1% ethylene glycol (EG) for two weeks in male Wistar rats. The animals were divided into prevention and treatment groups, each contained five sub-groups (10 rats for each). Prevention groups were treated for two weeks: control group (without treatment), EG group (1% ethylene glycol in drinking water), RSW 5, 10, and 15% groups (1% ethylene glycol + RSW 5, 10, and 15% in drinking water). The treatment groups received 1% EG for two weeks, then it was discontinued, and the RSW (10, 15, and 20%) was added to the drinking water for the next two weeks. The calcium oxalate (CaOx) depositions in the kidneys' tubules were evaluated by Hematoxylin and Eosin staining. The spring water was analyzed for its constituents. Results: Calcium oxalate crystals were significantly increased in EG group as compared to the control group (P < 0.05). Moreover, RSW did not significantly prevent CaOx crystals but alleviated CaOx crystals at 15 and 20% concentrations in the treatment protocol (P < 0.001). Conclusions: The hard water of Ramsar spring reduced CaOx crystals in nephrolithiatic rats, which may be due to its high calcium and magnesium content.

Background: Physical exercise aims to improve or maintain physical fitness. However, excessive physical exercise may cause increase of oxidative stress which leads to cellular injury, including in the proximal tubules of kidney. This research aims to find out the effect of single- and repeated- excessive swimming exercise to the kidney histopathology of male wistar rats (Rattus norvegicus). Methods: This research was an experimental study with complete random and post test only control group design. Twenty seven male wistar rats were divided into three treatment groups: control group, single- excessive swimming exercise group (45 minutes for one day), and repeated- excessive swimming exercise group (45 minutes/day for seven days). In the end of the treatment, the kidney of the rats were taken to be analyzed by using hematoxylin-eosin stain. The mean of proximal tubules injury of kidneys were counted by two observers using blinded method. Data were analyzed by using one way anova test. Result: The analysis showed there was a significant difference in the mean percentage of proximal tubules injury between control group and single swimming group as well as the repeated swimming group (Anova p=0,000), also there was significant difference between the treatment groups (p=0,020). The highest average of proximal tubules injury was in the single swimming group. Conclusion: Single- and repeated- excessive swimming exercise causes the proximal tubules injury of kidney.

The high incidence of alcoholic poisoning in Indonesia is caused by the use of methanol as a surrogate ingredient of nonconforming alcohol. The product of methanol metabolism is toxic to the liver. Ranitidine has been studied as an antidote to reduce the effect of methanol toxicity. The present study aimed to assess the effect of ranitidine administration on the liver damage of Wistar rats with acute methanol intoxication. This research was an experimental study with randomized and posttest-only control group design. A total of 24 male Wistar rats divided into four groups, each consisting of six Rats. The control group (K0) served as a reference normal value. The control group (K1) was intoxicated with methanol 7 g/kg body weight (b.w.) through rat gavage tube. Treatment groups were intoxicated with methanol and 15 minutes after that, Ranitidine (30 mg/kg b.w. (P1) or 60 mg/kg b.w. (P2)) was given intraperitoneally. Ranitidine administration was proven to protect the liver tissue from damage due to methanol intoxication as was indicated from the histopathological examination. Ranitidine with dose 60 mg/kg b.w. is better in reducing the degree of liver tissue damage in acute methanol intoxication rats.

Fractures are a serious health problem in Indonesia due to increasing prevalence. The healing process of fracture is disturbed by the oxidative stress that caused by imbalance quantity of free radical and antioxidant. An antioxidant such as polyphenol, which can be found in cocoa, is needed to suppress oxidative stress. The study aimed to investigate the effect of the ethanolic extract of cacao on fracture healing process in a rat model through MDA concentration and histopatological appearance. This study is in vivo experimental study with post-test only controlled group design. 30 male Wistar rats were randomized and divided into 5 groups. 1 group was rats without fractured. The negative control and three treatment groups were rats with fractured manually on left tibia under anesthesia and immobilized by bandage. The treatment groups treated with cocoa ethanolic extract in a dose of 125 mg/kgBW, 250 mg/kgBW, and 500 mg/kgBW orally for 21 days. The result showed that there was a significant different between the treatment groups and the negative control group on MDA concentration and histopatological appearance (p>0,05). The corelation between them were strong and had negative direction (R=-0,771). The study concluded that cocoa ethanolic extract had a positive effect to supress oxidation stress and increases the number of osteoblast on fracture healing process. Key words: cocoa ethanolic extract, polyphenol, fracture healing process, oxidative stress
