Sidaguri leaves (Sida rhombifolia L.) Have been shown to contain flavonoid compounds, where they are efficacious as hyperuricemia. This study aims to determine effectiveness ethanol extract of sidaguri leaves as antihyperuricemia in white rats. The study was conducted using the method of potassium oxanate induction and measured using glucometers. 15 animals were divided into 5 groups, namely negative control, positive control, group I combination of ethanol extract of sidaguri leaves 50 mg / kg body weight, group II ethanol extract of sidaguri leaves 100 mg / kg body weight, group III ethanol extract of sidaguri leaves 200 mg / kg body weight for 5 hours. Examination of antihyperuricemia effects is done by comparing the uric acid levels value of the rats before and after treatment. The results of this study indicate that the three dose ethanol extract of sidaguri leaves provide an antihyperuricemia effect and based on one-way Anova, Tuckey and LSD data analysis, shows that the dose of 50 mg / kg body weight is effective as antihyperuricemia and does not have a significant difference (p> 0.05). The conclusion of this study is that the dose is the most effective in decreases uric acid levels in white rats, which is a dose of 200 mg / kg body weight because it mostly decreased uric acid levels.

ABSTRACTBackground: Obesity is a disorder or disease characterized by the accumulation of excess fat in the body due to an imbalance in energy intake that is used for a long time. Accumulation of fat can reduce adiponectin, causing cardiac hypertrophy, endothelial vasodilation, and other cardiovascular diseases. Black garlic have high antioxidants in the form of S-Allylcysteine(SAC) which functions to increase adiponectin. Objective: To determine the effect of Black garlic on the histopathological picture of the heart and aorta of obese rats. Methods: This study was an experimental study with a randomized post-test only design with control group design with 5 groups of male white rats Sprague Dawley (Rattus novergicus) fed High Fat Fructose. Diet (HFFD) enriched with 1.25% cholesterol and 0.5% cholic acid for 8 weeks and was given black garlic intervention at doses of 450 mg / 200BW, 900mg / 200BW and 1350mg200 / BW for 4 weeks. Results: Giving black garlic significantly reduced body weight of rats (p = 0.001), and the results did not significantly reduce heart weight (p = 0.147), aortic weight (p = 0.061), histopathological changes in heart wall thickness (p = 0.423) and aortic wall thickness (p = 0.802). The effective doses of black garlic in this study were 450 mg / 200 grams BW, 900 mg / 200 grams rat BW and 1350 mg / 200 grams BW of rats. The optimal dose is 900 mg / 200 grams BW. Conclusion: Black garlic gave a significant reduction in body weight of rats and no significant reduction in heart weight, aortic weight, cardiac and aortic histopathological features.

Female Sprague-Dawley rats, 10-12-week old and weigh ing about 240 g, were injected intravenously with 237Np nitrate. In the toxicological study 77 rats served as controls and 28 rats per group received single doses of 5.2 and 26 kBq, respectively, per kg body weight. In addition, 12 rats of each injection level, sacrificed at defined points in time, were used for dosimetric studies. During the whole life-span the body weight and 237Np whole body-content of each animal were recorded. After death a detailed pathological examination was made of each animal in the cronical study. One day after injection 48% of the injected activity was in the skeleton, 9.3% in the liver, 3% in the kidneys and 4.4% in the rest of the organs. Whereas in all organs the activity decreased very fast, the half-life in the skeleton was about 1400 days. The bodyweights were comparable in the three groups, but the life span decreased from 800 days (control group) to 644 days after injection (26 kBq kg -1 body weight group). The main lesions in the female rats were mammary tumors (73%) and pituitary gland tumors (52%). With increasing activity the incidence of pituary gland tumors decreased and that of osteosarco mas increased from 1.3% (control group) to 32% (26 kBq kg-1 body weight group), whereas the remaining lesions showed no influence on the activity.

BuPiHeWei (BPHW) decoction, a classic Traditional Chinese Medicinal (TCM) prescription, has been widely used in clinical practice to relieve digestive symptoms caused by chemotherapy, such as diarrhea and vomiting. The present study aimed to investigate whether BPHW decoction exerted a protective role in the 5-Fu-induced intestinal mucosal injury in the rats by regulating the mechanisms of TLR-4/NF-κB signaling pathway. There were 35 Sprague Dawley rats randomly divided into four groups: normal control group, 5-Fu group, 5-Fu + BPHW decoction group (10.5 g/kg, for five continuous days), and 5-Fu + Bacillus licheniformis capsule group (0.2 g/kg, for five continuous days). Animal models were established by intraperitoneal injection of 5-Fu (30 mg/Kg, for five consecutive days). At the end of the treatment period, body weight, diarrhea score, and histological examination were examined. Furthermore, the expression of TLR-4/NF-κB pathway was detected to reveal its mechanism. The results showed that BPHW decoction effectively reduced diarrhea score and increased body weight and height of villi after 5-Fu chemotherapy. In addition, BPHW decoction could significantly inhibit the expression of TLR-4, NF-κB, and inflammatory factors (including TNF-α, IL-1β, and IL-6) in the intestine, and the efficacy was significantly higher than that of Bacillus licheniformis capsule. In summary, BPHW decoction might be considered an effective drug to alleviate intestinal mucosal injury in the rats induced by 5-Fu.

Acalypha Indica

Acalypha indica is one of the medicinal plants that have been used since ages to treat various diseases such as pneumoniae, asthma and skin diseases. This study aimed to explore the subchronic toxicity effect of Acalypha indica on Sprague Dawley rats based on haematological and biochemical parameters. The extract of Acalypha indica was prepared by aqueous extraction technique. 48 Sprague Dawley rats aged 7 weeks, weighing 150-200g were randomly divided into four groups, 6 animals per gender. A control group received water vehicle while three treated groups received the extract at dosage of 100 (low dosage group), 200 (medium dosage group) and 300 (high dosage group) mg/kg body weight. The sample was administered orally by using oral gavage daily for 90 days. No sign of toxicity and mortality was recorded in all groups throughout the study. There were no significant different (p>0.05) in body weight gain, food and water intake between control and treatment group. However, there was significant different in uric acid between control and high dosage group of male and female rats but the mean were in normal range. There were also reduced in mean of urea and creatinine in all dosage group of male and urea for all dosage group of female. Statistically significant reduced in urea was recorded between control and high dosage group of male only. Other parameters showed no significant different between control and treatment groups. Therefore, Acalypha indica is safe for human consumption and might be potential in reducing kidney damage problem.

Objectives: Drugs can cause undesired effects on the fetus during pregnancy, especially embryonic/organogenesis which could lead to defects in the fetus because some types of drugs can penetrate the placenta and will undergo biotransformation into a highly reactive compound that has the potential to become a teratogenic compound. The aim of this research was to examine the teratogenic effect of bintangur leaves (Calophyllum soulattri Burm. F) ethanol extract to Sprague Dawley strain white rats. Methods: The white rats are divided into four treatment groups: Control group was given carboxymethyl cellulose Na 1%, comparison group was given trimethoprim 360 mg/kg BW, C. soulattri leaves ethanol extract (CLE) 100 mg/kg BW, and CLE 500 mg/kg BW. The treatment was administrated since organogenesis period. Cesarian section was performed to pregnant rat at the 20th day to separate the fetuses. Observation covered body weight of pregnant rats, fetal biometric, morphological malformation, and skeletal formation. Results: CLE 100 mg/kg BW and 500 mg/kg BW did not cause any change in the number of a living fetus, body weight, and length of fetuses like the comparison group. Both doses of CLE shown have a normal skeletal formation. Resorption was found in the comparison group and CLE 100 mg/kg BW with the percentage was 65.21% and 6.67%. It was found that there is no significant difference (p<0.05) between both doses of CLE compared to control group. Conclusion: From the results, it is concluded that CLE did not have the teratogenic effect.

DespiteEuphorbia hirtaL. ethnomedicinal benefits, very few studies have described the potential toxicity. The aim of the present study was to evaluate thein vivotoxicity of methanolic extracts ofE. hirta. The acute and subchronic oral toxicity ofE. hirtawas evaluated in Sprague Dawley rats. The extract at a single dose of 5000 mg/kg did not produce treatment related signs of toxicity or mortality in any of the animals tested during the 14-day observation period. Therefore, the LD 50 of this plant was estimated to be more than 5000 mg/kg. In the repeated dose 90-day oral toxicity study, the administration of 50 mg/kg, 250 mg/kg, and 1000 mg/kg/day ofE. hirtaextract per body weight revealed no significant difference (P>0.05) in food and water consumptions, body weight change, haematological and biochemical parameters, relative organ weights, and gross findings compared to the control group. Macropathology and histopathology examinations of all organs including the liver did not reveal morphological alteration. Analyses of these results with the information of signs, behaviour, and health monitoring could lead to the conclusion that the long-term oral administration ofE. hirtaextract for 90 days does not cause sub-chronic toxicity.

Wood Creosote

Seirogan, an herbal medicine containing wood creosote (tablets, 10.0% w/w), has been developed and marketed for almost a century in various countries for the control of acute diarrhea and treatment of associated symptoms, such as abdominal cramping. Wood creosote (CAS no. 8021–39–4) is a mixture of simple phenolic compounds, including guaiacol and creosol and related compounds, and is chemically distinct from, and should not be confused with, coal tar creosote, a known carcinogen. In the current study, the oncogenic potential of wood creosote was assessed in a 96/103-week oral gavage study in Sprague-Dawley rats. Groups of 60 rats/sex received wood creosote at dose levels of 20, 50, or 200 mg/kg body weight [bw]/day. An additional group of rats received the vehicle, 0.5% carboxymethylcellulose in deionized, distilled water, at the same dose volume as the treatment groups (10 ml/kg) and served as the controls. Treatment-related decreases in survival, body weight, and food consumption, as well as increased incidences of clinical signs that included rales, decreased activity, and salivation, were noted at 200 mg/kg bw/day when compared with the control group. There was an increased incidence of reddened and edematous lungs in rats from the 200 mg/kg bw/day group that died during the study. The lung findings were suggestive of test article aspiration during dose administration or agonal aspiration preceding and possibly resulting in death, especially because these observations were not seen in animals that survived to scheduled sacrifice. Additionally, phenols are generally recognized as having corrosive properties. There were no changes in clinical pathology and no increases in neoplastic or non-neoplastic lesions, excluding the lung findings, related to treatment with wood creosote at any dose level. Although the results of this study indicate that the maximum tolerated dose of wood creosote was met or exceeded at 200 mg/kg bw/day, there was no evidence of oncogenicity at any dose level. The lack of any evidence of oncogenicity supports the safety profile of the active ingredient in Seirogan, wood creosote.
