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

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.

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.

Jatropha Curcas L

Abstract: Indonesia is a tropical country with the second largest biodiversity in the world after Brazil. Jatropha curcas (Jatropha curcas L.) was believed as a pain reliever (analgesic). This study was aimed to prove the analgesic effect of Jatropha curcas leaf extract on Wistar rats (Rattus norvegicus). This was an experimental study using hot stimulus method in the form of temperature of 65°C. Subjects were 15 male Wistar rats divided into 5 groups. Group 1, the negative control group; group 2, the positive control group given paracetamol 40 mg/kgBW; and 3 treatment groups (groups 3, 4, and 5) given Jatropha curcas extract in several doses (300 mg/kgBW, 600 mg/kgBW, and 1200mg/kgBW). Observation of Wistar rat respons (licking and jumping) was performed for 1 minute at minutes -30, 60, 90, and 120 after treatment. The results showed that the mean values of response against heat decreased in accordance to time and reached the lowest values at minute 120, except group 5 (the extract dose of 1200mg/kg BW) which reached the lowest value at minute 90. Overall, the lowest mean value was found in group 4 (the extract dose of 600mg/kg BW). Conclusion: Jatropha curcas (Jatropha curcas L.) leaf extract had an analgesic effect on Wistar rats (Rattus norvegicus).Keywords: Jatropha curcas L., Rattus norvegicus, analgesic Abstrak: Indonesia merupakan negara beriklim tropis dengan keaneka ragaman hayati terbesar kedua di dunia setelah Brazil. Penelitian ini bertujuan untuk mengetahui efek analgesik pemberian ekstrak daun jarak pagar (Jatropha curcas L.) pada tikus Wistar (Rattus norvegicus).

Pulmonary contusions are injuries to the lung parenchyma that often result from blunt trauma to the chest wall. This injury will activate the inflammatory response which can produce the effects of oxidative stress so that eventually lung damage occurs. Several studies have identified the effects of Jati Belanda leaves extracts related to the inflammatory process and their effects as antioxidants. This research is an in vivo experimental study with a prepost-test with control group design approach that aims to determine the effectiveness of the extracts of Jati Belanda (Guazuma ulmifolia) in its protection against pulmonary alveolar cells by pretreatment pulmonary contusions. The subjects of this study were white rats (Rattus norvegicus) Wistar strain which were divided into 5 groups namely positive control, negative control, Dutch teak leaf extract 125 mg / kgBB, 250 mg / kgBB and 500 mg / kgBW. Rats were induced by dropping a weight of 400 grams as high as 50 cm. The results of the study of Jati Belanda Leaf Extract (EDJB) all doses and positive control can significantly reduce levels of myeloperoxidase expression (p <0.05). Therefore, it can be concluded that the extracts of Jati Belanda leaves (Guazuma ulmifolia) are all effective doses in reducing the expression of myeloperoxidase in pulmonary tissue of Wistar rats induced by pulmonary contusions.
