ABSTRACTJatropha curcas L. leaves is plants containing saponins, flavonoid compounds such as kaempferol, nicotoflorin, quersitin, astragalin, ricinin and vitamin C. Flavonoids showed more than one hundred kinds of bioactivity, which is antipyretic, analgesic and anti-inflammatory effects. Several researches informed that flavonoid compound had antipyretic activity. The aim of this study was to examined the effect of ethanolic extract of Jatropha curcas L. leaves as antipyretic on white Wistar male rats (Rattus norvegicus) induced with DPT. There were 15 rats tested, divided into 5 groups that is negative control (CMC 1%), positive control (paracetamol) and treatment group of physic nut leaves extract 200 mg, 400 mg and 800 mg. Every rat was induced by fever using 0,4 ml of DPT vaccine intramuscularly. The temperature was measured before the rats were induced, 2-3 hour after induced and every 30 minute for 3 hours. The data obtained were analyzed by ANOVA (Analysis of Variants) and LSD. The results showed that the dose group of Jatropha curcas L. leaves ethanol extract had comparable activity with positive control of paracetamol in reducing fever. The conclusion was the ethanol extract of Jatropha curcas L. leaves has an antipyretic activity that could reduce temperature on white Wistar male rats at a dose of 200 mg, 400 mg and 800 mg. Keywords: Jatropha curcas L., antipyretic, Rattus norvegicus ABSTRAKDaun Jarak Pagar (Jatropha curcas L.) merupakan tanaman yang mengandung saponin, senyawa flavonoida antara lain kaempferol, nikotoflorin, kuersitin, astragalin, risinin dan vitamin C. Flavonoid menunjukkan lebih dari seratus macam bioaktivitas, antara lain efek antipiretik, analgetik dan antiinflamasi. Penelitian ini bertujuan untuk menguji aktivitas antipiretik ekstrak etanol daun jarak pagar (Jatropha curcas L.) terhadap tikus putih jantan galur wistar (Rattus norvegicus) yang diinduksi vaksin DPT. Hewan uji yang digunakan sebanyak 15 ekor dan dibagi menjadi 5 kelompok yaitu kontrol negatif (CMC 1%), kontrol positif (parasetamol) dan kelompok dosis uji yaitu pemberian ekstrak daun jarak pagar 200 mg, 400 mg dan 800 mg. Setiap tikus diinduksi demam dengan vaksin DPT dosis 0,4 ml secara intramuskular. Pengukuran suhu dilakukan sebelum induksi, 2-3 jam setelah pemberian induksi dan setiap 30 menit selama 3 jam. Data yang diperoleh dianalisis dengan menggunakan uji ANOVA (Analysis of Variance) dan uji LSD (Least Significant Different). Hasil penelitian menunjukkan bahwa kelompok dosis ekstrak etanol daun jarak pagar memiliki aktivitas yang sebanding dengan kontrol positif parasetamol dalam menurunkan demam. Kesimpulannya ekstrak etanol daun jarak pagar (Jatropha curcas L.) memiliki aktivitas antipiretik yang dapat menurunkan suhu tubuh pada tikus putih jantan galur wistar (Rattus norvegicus) pada dosis 200 mg, 400 mg dan 800 mg. Kata kunci: Jatropha curcas L., antipiretik, Rattus norvegicus

This investigation was aimed to study the effect of 2,3-dimercapto-1-propanesulfonic acid (DMPS) on mercuric chloride (HgCl2)-induced alterations in urinary excretion of various carnitine fractions including free carnitine (FC), acylcarnitine (AC), and total carnitine (TC). Different groups of Wistar male rats were treated with HgCl2 at the doses of 0.1, 0.5, 1.0, 2.0, and 3.0 mg/kg body weight, and the animals were sacrificed at 24 hours following HgCl2 injection. A separate batch of animals received HgCl2 (2 mg/kg) with or without DMPS (100 mg/kg) and sacrificed at 24 or 48 hours after dosing. Administration of HgCl2 resulted in statistically significant and dose-dependent increase in the urinary excretion of FC, AC, and TC in rats. However, the ratio of urinary AC:FC was significantly decreased by HgCl2. Pretreatment with DMPS offered statistically significant protection against HgCl2-induced alterations in various urinary carnitine fractions in rats.

Insecticides and toxicants abound in nature, posing a health risk to humans. Concurrent exposure to many environmental contaminants has been demonstrated to harm myocardial performance and reduce cardiac oxidative stress. The purpose of this research was to study the protective effect of vitamin C (Vit C) on quinalphos (QP)-induced cardiac tissue damage in rats. Eighteen albino male rats were randomly categorised into three groups (n = 6). Control, QP group: rats received distilled water. QP insecticide treatment: an oral administration of QP incorporated in drinking water. QP + Vit C group: rats received QP and Vit C. All the experiments were conducted for ten days. Decline of cardiac antioxidant biomarkers catalase (CAT) and reduced glutathione (GPx) along with increased proinflammatory markers tumour necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) indicated oxidative and inflammatory damage to the heart following administration of QP when compared to control rats. The light microscopic and ultrastructure appearance of QP-treated cardiomyocytes exhibited cardiac damage. Administration of Vit C showed decreased oxidative and inflammatory biomarkers, confirmed with histological and electron microscopic examination. In conclusion, Vit C protected the heart from QP-induced cardiac damage due to decreased inflammation and oxidative stress.

Our previous findings suggested the existence of stressor-specific behavioural and cognitive responses in rats. In the present study, restraint stressor (immobilization, IMO) and restraint stressor combined with partial immersion of rats into water (IMO+C) were applied for 1 hour to Wistar male rats and their spontaneous behaviour was examined in the open field test. The classic behavioural parameters were recorded: crossing, rearing, and resting. When tested 1 and 4 hours after IMO+C, animals exhibited strong suppression of locomotor and exploratory activity (crossing and rearing); partial inhibition of both behavioural variables was found after IMO. Thus, substantial differences were observed in dependence on the length of period between the end of stressor application and the start of testing. In testing performed one week later, the locomotor and exploratory activity levels of both IMO and IMO+C animals corresponded to the control ones. These data suggest a differential behavioural response to both used stressors that may result from their different proportion of psychical and physical components. In conclusion, our results provide other data for the support of differential effects of two types of restraint stressors on spontaneous behaviour of animals exposed to a novel environment.

Although cisplatin is a potent anticancer drug, it instigates oxidative and pro-inflammatory reactions that pose significant and distressing clinical symptoms. Therefore, this study investigated the effects of vitamin C and (or) l-carnitine on cisplatin-induced gastric mucosa damage in rat. The rats were allocated into 6 groups (n = 5). The control group received distilled water, while the treatment groups received cisplatin alone (CIP), or cisplatin with vitamin C, l-carnitine, or their combination. Cisplatin caused disruption of the gastric mucosa histoarchitecture and altered the mucus barrier function. Moreover, the stomach tissue of the CIP-treated group showed increased levels of oxidative stress markers (malondialdehyde and H2O2) and decreased activities of antioxidant (superoxide dismutase, glutathione peroxidase, catalase, glutathione S-transferase) and non-antioxidant (reduced glutathione) enzymes. These deleterious events were accompanied with significant increases in pro-inflammatory cytokines and inflammatory infiltration markers, myeloperoxidase and inducible nitric oxide synthase. However, the administration of both vitamin C and l-carnitine, and not either of the two showed additive effects in attenuating the adverse effects of cisplatin. The histological results agreed with the biochemical assays. The study concluded that the combined administration of vitamin C and l-carnitine, but not the single therapy, could prevent the adverse effects of cisplatin on gastric tissue.
