Sonchus Arvensis

Sonchus arvensis L. leaves have been used traditionally to treat various disease conditions. This study is designed to evaluate cardioprotective potential of ethanol extract of S. arvensis leaves on isoproterenol-induced myocardial infarction in Wistar rat. Male Wistar albino rats were divided into three main groups: negative control (saline only), positive control (isoproterenol only), and S. arvensis extract treated groups. S. arvensis extract was administered in three doses; 50, 100, and 200 mg/kg b.w. p.o for 14 days. On day 13 and 14, isoproterenol (85 mg/kg bw) was given intraperitoneally to positive control and extract treated groups. The parameters studied were cardiac biomarker enzymes which were Creatine Kinase (CK), Creatine Kinase-MB (CK-MB), Aspartate Transaminase (AST), Alanine Transaminase (ALT) and Lactate Dehydrogenase (LDH). The results showed that S. arvensis at dose of 50 mg/kg b.w. could significantly (P<0.05) reduce the level of CK, CK-MB, AST, ALT, and LDH in myocardial infarcted rats compared to positive control. The increase of the dose of S. arvensis extract was not followed by an increase of its cardioprotective activity. In conclusion, Sonchus arvensis L. leaves extract at dose of 50 mg/kg b.w. has potential to be developed as cardioprotective drug.

Oxidative stress is an imbalance between free radicals and antioxidants, and is an important etiological factor in the development of hypertension. Recent experimental evidence suggests that subpressor doses of angiotensin II elevate oxidative stress and blood pressure. We aimed to investigate the oxidative stress related mechanism by which a subpressor dose of angiotensin II induces hypertension in a normotensive rat model. Normotensive male Wistar rats were infused with a subpressor dose of angiotensin II for 28 days. The control group was sham operated and infused with saline only. Plasma angiotensin II and H2O2 levels, whole-blood glutathione peroxidase, and AT-1a, Cu/Zn SOD, and p22phox mRNA expression in the aorta was assessed. Systolic and diastolic blood pressures were elevated in the experimental group. There was no change in angiotensin II levels, but a significant increase in AT-1a mRNA expression was found in the experimental group. mRNA expression of p22phox was increased significantly and Cu/Zn SOD decreased significantly in the experimental group. There was no significant change to the H2O2 and GPx levels. Angiotensin II manipulates the free radical-antioxidant balance in the vasculature by selectively increasing O2− production and decreasing SOD activity and causes an oxidative stress induced elevation in blood pressure in the Wistar rat.

Test Materials

Psidium guajava leaves have been proven be antiallergic. From the results of previous research, the ethanol extract of leaves is included in the class materials "Practically Non-Toxic." However, repeated administration may cause toxic effects on body organs, one of which was gaster. Subchronic toxicity had been carried out on 20 male Wistar rats and 20 female wistar albino rats. The test materials were administered orally, every day for 28 days. There are 3 (three) doses of test materials which were 250 mg, 500 mg, and 750 mg/kg BW. Observation of the general toxic effect was performed everyday, then organ sampling was performed on day 29 to examined gaster histology and score using Barthel-Manja methods. The result showed that administration of Psidium guajava leaves extract for 28 days caused physical and behavioral changes, caused soft and mucous feces, and also respiratory disorder. But the extract at dose 250 mg, 500 mg and 750 mg/kg BW did not caused changes on gaster histology profile and score. In conclusion, the extract did not have subchronic toxicity effect on gaster rat, but might caused general toxic effect in the higher dose.

A B S T R A C TThis study aims to determine the effect of paprika ethanol (capsicum annuum) onblood sugar levels of alloxan-induced Wistar rats (rattus norvegicus). This type ofresearch is experimental. The method used was pre test and post test with controlgroup design. The results of this study indicate that for Post Test 1 or after beinggiven treatment for 7 days, the average result shows that there is an effect of givingred paprika ethanol extract on blood sugar levels in Wistar rats where the significantvalue of each treatment is all less than 0.05. For Post Test 2 or after being giventreatment for 14 days, only at a dose of 250 that has no effect on blood sugar levelsof the rats, because the significant value is 0.813 greater than 0.05, for othertreatments it has a significant effect because the significant value is more smallerthan 0.05.
