<p>Colorectal carcinogenesis induced by cigarette smoke requires at least 30-40 years. This long time duration causes an animal research conducted becomes relevant. This research was carried out to observe colorectal carcinogenesis due to cigarette smoke exposure in Wistar Rat. The observations focused on changes in epithelial morphology and expression of APC, MSH2 and MLH1. Twenty male Wistar rats inbreed strain were randomly allocated into control group and experimental group exposure to cigarettes smoke for 14 weeks and 28 weeks sequentially.  Colorectal epithelial morphology was assessed on the histopathology examination, whereas the expression of APC, MSH2 and MLH1 was assessed on aspect of immunohistochemistry. The comparative analysis between the two groups was performed using non-parametric Mann-Whitney U test. Histology of colorectal epithelium showed pattern of colitis associated cancer that was significant both in 14 weeks and 28 weeks of treatment.  This research indicated negative expression of APC, MSH2 and MLH1 in the colorectal cancer that were significant at 28 weeks of exposure. This research implies that chronic exposure to cigarette smoke can induce colitis associated colorectal cancer through decreased expression of APC, MSH2 and MLH1. </p>

OBJECTIVE: To describe a new murine model of cigarette smoke-induced emphysema. METHODS: Twenty-four male Wistar rats were divided into two groups: the cigarette smoke group, comprising 12 rats exposed to smoke from 12 commercial filter cigarettes three times a day (a total of 36 cigarettes per day) every day for 30 weeks; and the control group, comprising 12 rats exposed to room air three times a day every day for 30 weeks. Lung function was assessed by mechanical ventilation, and emphysema was morphometrically assessed by measurement of the mean linear intercept (Lm). RESULTS: The mean weight gain was significantly (approximately ten times) lower in the cigarette smoke group than in the control group. The Lm was 25.0% higher in the cigarette smoke group. There was a trend toward worsening of lung function parameters in the cigarette smoke group. CONCLUSIONS: The new murine model of cigarette smoke-induced emphysema and the methodology employed in the present study are effective and reproducible, representing a promising and economically viable option for use in studies investigating the pathophysiology of and therapeutic approaches to COPD.

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.

BACKGROUND: Cigarette smoke has a variety of dangerous chemicals and free radicals that can potentially cause infertility. One of the plants that are reported to have medicinal properties and have active compounds as antioxidants is Binahong (Anredera cordifolia (Ten.) Steenis). AIM: This study aims to investigate the effectiveness of A. cordifolia leaf extract (ACLE) in increasing the fertility of male Wistar rats after exposure to cigarette smoke. METHODS: Twenty-four adult male rats were divided into six groups (age 8–10 weeks, weight 200–250 g): Group 1 (normal control) received aquades (1 ml/day) without being given cigarette smoke, Group 2 received exposure to smoke without being given ACLE, Group 3 received cigarette smoke exposure + 25 mg/kg ACLE, Group 4 received cigarette smoke exposure + 50 mg/kg ACLE, Group 5 received cigarette smoke exposure + 75 mg/kg ACLE, and Group 6 received exposure to cigarette smoke + 100 mg/kg of ACLE. To produce smoke from cigarettes and expose rats to the smoke, a Smoke chamber is used. Rats in the treatment group were exposed to cigarette smoke for 2 weeks (40–60 s daily for 6 days each week). The evaluation of male rat fertility was carried out by measuring body weight, genital weight (testis and epididymis), and spermatozoa spermogram (velocity, motility, morphology, and total number). RESULTS: The least significance different test results showed no significant difference in the rate of weight gain between treatments, standard control, and negative control groups. The average testicular weight of rats exposed to cigarette smoke for 14 days was significantly different from normal controls and doses of 50, 75, and 100 mg/kg body weight. However, at a dose of 25 mg/kg of body weight had not shown a significant increase compared to control. The average spermatozoa velocity reached 12.43 mm2/s and 13.36 mm2/s. The spermatozoa velocity increased significantly at a dose of 100 mg/kg body weight. CONCLUSIONS: ACLE at a dose of 100 mg/kg body weight was effective in increasing the fertility of male Wistar rats exposed to cigarette smoke.
