Liver Histological Response of Hyperlipidemic Male Rat (Rattus norvegicus) to Lakum Leaf Extract

High salt diet and prednisone administration will increase blood pressure which chronically causes heart muscle remodeling so that it appears macroscopically as left ventricular hypertrophy. Bay leaf extract contains flavonoids which can lower blood pressure and decrease left ventricular thickening. To determine the effect of bay leaf extract (Syzygiumpolyanthum) on the left ventricle thickening of rat heart (Rattus norvegicus wistar strain) in hypertensive model. True experimental post-test only controls group design with simple random sampling technique. The subjects of this study were 25 male Wistar rats aged 2-3 months weighing 150-200 grams. Rats were induced with prednisone 1.5 mg/ KgBW / day in 2% NaCl for 6 weeks followed by administration of bay leaf extract at a dose of 70 mg/ KgBW, a dose of 140 mg/ KgBW, and a dose of 280 mg/ KgBW. Data analyzed by One Way ANOVA, Post Hoc Bonferroni, followed by Linear: One Way ANOVA test showed significant differences between treatments (p = 0.000). The Bonferroni Post Hoc test concluded that there were significant differences in the treatment of the P2 and P3 groups. Linear regression test obtained R square 0.663 and obtained the equation Y = 1965.838 - 1.275X. The extract of bay leaf (Syzygiumpolyanthum) has an effect on decreasing the left ventricle thickening of the white male rat heart (Rattus norvegicus wistar strain) hypertension model.

The objective of this study was to determine the effect of centella leaf extract administration on decreased of the molecule cAMP responsive element modulator (CREM) expression in the testicular seminiferous tubules of male rats (Rattus norvegicus). Eight rats, aged 3.5 months with 150-250 grams of body weight (BW) were used in this study. All rats were divided randomly into four groups as if K0 as a control group whereas K1, K2, and K3 were given the centella leaf extract with doses 125, 250, and 500 mg / kg body weight respectivelly that given once daily for 30 days. At the end of the treatment, rats were sacrificed and their testes were collected and subsequently fixed in buffered neutral formalin (BNF) 10% as fixative solution for histological preparation. The CREMs expressions were detected using immunohistochemical methods. The results showed that the number of CREM expression in the seminiferous tubules significantly differ (P <0.05) between K0 and the treatment group (K1, K2, and K3). Conclusion, the administration of centella leaf extract with of the dose 125, 250, and 500 mg/kg BW can decreased CREM expression spermatids of testicular seminiferous tubules in male rat.

This study aimed to determine the ability of neem leaf extract to maintain the normal blood profile of white male rat (Rattus norvegicus) infected with Trypanosoma evansi. A total of 24 male white rats were divided into 6 groups. The K0 group as the negative control received no T. evansi infection and no neem leaf extract. Furthermore, K1 group (positive control) only infected with T. evansi, K2 and K3 were given neem leaf extract 50mg/kg BW and 100mg/kgBW, while K4 and K5 were given neem leaf extract 400mg/KgBW and K5 800mg/kgBW. The neem leaf extract was administered for 3 consecutive days after infection established. The blood of the rats was collected to determine the amount of erythrocyte and leukocyte, hemoglobin level and hematocrit value. The data were analyzed using Analysis of Variance (ANOVA) through SPSS for Windows 16.0. The averages (+SD) of erythrocyte of K0, K1, K2, K3, K4, and K5 were 5,64±0,57; 2,31±1; 1,93±0; 0; 2,55±0,33; and 2,56±0,48. The amount of leukocyte were 4,46±1,09; 4,45±1,91; 5,25±0; 0; 8,42±1,66; and 8,14± 5,17. The value of hemoglobin were 12,00±0,47; 10,50±0,57; 4,30±0; 0; 5,60±0,20; and 9,03±0,66. The level of hematocrit 38,00±1,83; 25,00±9,90; 15±0; 0; 18,00±2,65, and 20,75±1,71. The result showed that the administration of neem leaf extract with doses 400mg/kgBW and 800mg/kgBW were difference significantly (P0.05) compare to the positive control of rats, but could not equalize blood profile of uninfected white male rats

Heavy Training

Overtraining syndrome is a decrease in physical capacity, emotions and immunity due to training that is too often without adequate periods of rest. Overtraining is often experienced by athletes who daily undergo heavy training with short break periods. This research aims to look at the effect of overtraining aerobic physical exercise on memory in mice. The research method was experimental in vivo with the subject of adult male rat (Rattus Norvegicus) Winstar strain aged 8-10 weeks, body weight 200-250 gr. Divided into three groups, namely the control group, aerobic group and overtraining group. The results of memory tests with water E Maze showed an increase in the duration of travel time and the number of animal errors made by the overtraining group (p = 0.003). This study concludes that overtraining aerobic physical exercise can reduce memory in rat hippocampus.

Background: Peperomia pellucida L'HBK or known as messengers in the Indonesian plant is a herbaceous plant that belongs to the family Piperaceae. This study aimed to determine the effect of the stem and leaf extract cream messengers to the healing process of burns in rats (Rattus norvegicus. Methods: This was an experimental study using a completely randomized design. Test animals were divided into three groups, each - each group consisted of 3 rats. The first group is the negative control group (distilled water), the second group is a positive control group (Bioplacenton®), the third group is the group treated stem and leaf extract cream errand. The diameter of the wound and fibroblasts observed histopathology and is used as an indicator of the healing process of burns. The burns were treated and observed the healing effect for 20 days. Data were analyzed statistically wound diameter using ANOVA followed by LSD test. Results: The results showed the cream extracts of stems and leaves telling effect on the healing process of burns on rats. Conclusion: The results also showed that the treatment group and the leaf stem extract cream messengers and control groups positively influence the healing process of burns significantly when compared to the negative control group. Meanwhile, the treatment group stem and leaf extract cream messengers have no preformance difference influence the healing process of burns a significant positive control group

Red calliandra (Calliandra calothyrsus Meissn.) leaf have the potential as phytoestrogens. In this study, adult female ovariectomized rats (as a model of menopause women) were given calliandra leaf extract containing estrogenic flavonoids. This study was an experimental design with a Completely Randomized Design (CRD). Forty-five ovariectomized female rats were divided into five groups i.e. untreated control (K), and the treatment group given 80% of C. calothyrsus ethanolic leaves extract doses 25 mg/ kg bw (P1), 50 mg/ kg bw (P2), 75 mg/ kg bw (P3) and 100 mg/ kg bw (P4). The test suspension was given once a day at 24-hour intervals by gavage as much as 0.5 ml/rat/day for two months. At the end of the treatments, blood was collected for blood biochemical tests including hemoglobin levels, hematocrit values, blood glucose and proteins levels. The results showed that C. calothyrsus leaf extract did not negatively affect the health status of the animals through blood biochemical parameters, i.e. hemoglobin levels, hematocrit values, and glucose and protein levels of ovariectomized female rats.
