Background: Annona cherimola Mill. (A. cherimola) is mainly characterized by its antioxidant and cytoprotective properties due to their content of phenolic compounds. Objective: To evaluate antioxidant and hepatoprotective activity of ethanol extract of leaves from A. cherimola against induced toxicity by paracetamol in rats. Methods: Amount of total phenolics compounds of ethanol extract of A. cherimola Mill. was determined by the Folin-Ciocalteu method and antioxidant activity was evaluated by DPPH method. Three doses of the ethanol extract of leaves of A. cherimola (250, 500 and 750 mg/Kg/day) were administered to rats and it was evaluated biochemical blood parameters: aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were measured, liver tissue was removed for histopathological analysis. Results: Ethanol extract of leaves from A. cherimola had 41.26 mg GAE/g extract and antioxidant DPPH Scavenging Activity had 85.51\%. A. cherimola reduced blood levels of ALT, AST and ALP, compared to control group Paracetamol, ethanol extract, being more effective at doses of 750 mg/Kg/day. Histopathological evaluation suggested that A. cherimola decreased hepatic necrosis and degenerative process induced by paracetamol. Conclusions: Hepatoprotective activity of ethanol extract of leaves of A. cherimola was demonstrated, being hepatoprotective activity dose dependent and the mechanism may involve antioxidant activity and total polyphenols found in extract of this plant.

Introduction: Lead is one of the most dangerous heavy metals in the environment. Contaminated drinking water, battery manufacturing, lead paints, and industrial pollutants are all sources of lead exposure. Lead exposure can cause oxidative stress and is related to many health problems. To prevent oxidative stress caused by lead, the body needs additional antioxidants from the outside body. Syzygium cumini leaf is abundant in antioxidants, which help to minimize oxidative stress caused by lead. Methods: The rats were divided into three groups: negative control, positive control (lead acetate 40 mg/kg BW, 30 days), and treatment (lead acetate 40 mg/kg BW and Syzygium cumini leaves extract 150 mg/kg BW, 30 days). At the end of the experiment, blood was collected and prepared to measure malondialdehyde and catalase activity. Results: The leaf extract of Syzygium cumini reduced serum malondialdehyde levels while increasing catalase activity. Conclusion: Lead exposure induces oxidative stress, which can be reduced by Syzygium cumini{\textquoteright}s leaves.

Peganum harmala L., Zygophyllaceae popularly known as Wild Syrian rue, a well-known plant in folk medicine for many pharmacological uses including antispasmodic activity. Chemical composition of the plant showed that the most important constituents of this plant are betacarboline alkaloids such as harmalol, harmaline, and harmine. In this work, we aimed to evaluate the effects of these three major harmala alkaloids on induced rat ileum contractions, induced by acetylcholine, BaCl2 and KCl. Of these three harmala alkaloids, harmalol and harmaline produced a concentration-dependent spasmolytic activity, which was found to be reversible (i.e. disappeared after tissue wash-up. Both alkaloids inhibited acetylcholine and KCl-induced ileum contractions but BaCl2 -induced contractions were only inhibited by harmalol but not harmaline. Harmine did not show any inhibitory activity.

Objective: to evaluate the efficacy of Allium sativum, Curcuma mangga, and Acorus calamus extract combination on female rat fertility. Methods: Thirty-six female rats were randomized divided into 9 groups (n=4): C- (no treatment); C+ (clomiphene citrate); composition 1 (A. sativum 36\%: C. mangga 36\%: A. calamus 28\%) with 3 doses i.e T1, T2 \& T3 of 50, 75 \& 100 mg/kg BW; composition 2 (A. sativum 35\%: C. mangga 40\%: A. calamus 25\%) with 3 doses i.e T4, T5 \& T6 of 50, 75 \& 100 mg/kg BW and T7 (Subur Kandungan herb{\texttrademark}). Treatment was given every day for 15 days. Results: The results revealed that all treatments affected reproductive hormone and uterine histology profile. However, T1 produced the highest estrogen and progesterone levels, and T2 produced the highest endometrial and myometrium thickness, as well as the number of endometrial glands. Furthermore, the hormonal profile in T1 and histological profile of uterus in T2 were not significantly different from those of T7 group. Conclusions: Combined A. sativum, C. mangga, and A. calamus extracts could be used to increase fertility in female rat. The most effective treatment in this study was dose of 50-75 mg/BW in both compositions.

Background: Experimental diabetes can be induced using chemical agents such as streptozotocin. Objective: This study aimed to investigate the effect of streptozotocin (STZ) which is most important agent to produce experimental diabetic model at two different doses on serum protein fractions in rat models. Materials and Methods: Twenty-four male rats that weighed an average of 250 g and were 3\–4 months old were used as the experimental models. They were sorted into three groups composed of eight rats each of STZ 55 mg/kg, STZ 65 mg/kg and control. Diabetes was induced by administering STZ 55 mg/kg and 65 mg/kg intraperitoneally. The serum protein fractions were analyzed by cellulose acetate electrophoresis. Results: No significant difference was observed between the groups for all fractions except alpha-2 and beta globulins. The alpha-2 and beta globulin levels were significantly higher in the 55 mg/kg group than in the 65 mg/kg STZ and control groups (p\<0.05). Conclusion: This increase may be due to the involvement of different proteins in the alpha-2 and beta globulin protein fractions.

Oroxylum indicum is a frequently reported traditional medicinal plant known to possess antiproliferative and antitumor activity. The present study investigated the effect of crude methanolic bark extract of Oroxylum indicum on testosterone induced benign prostate hyperplasia (BPH) in rat. Adult male rats were given either corn oil or testosterone dissolved in corn oil and testosterone with aqueous methanolic bark extracts of Oroxylum indicum (10, 50 and 100 mg/kg/day) for 14 days. The inhibitory effect of Oroxylum indicum on testosterone induced hyperplasia was evaluated by prostatic index and histopathological examination. Serum marker of liver injury (alanine aminotransferase, ALT and aspartate aminotransferase, AST) and liver histopathological examination were also conducted. Compared with testosterone induced BPH model group, Oroxylum indicum extract treated groups exhibited significant reduction in the prostatic index. Oroxylum indicum treated group also exhibited reduced hyperplasia of prostatic epithelium likewise finasteride treated group. Aqueous methanolic extract of Oroxylum indicum significantly inhibited testosterone induced prostate hyperplasia thus indicated the presence of efficient ingredients which can be used for the treatment of BPH.
