Background: Oxidative stress, inflammation, and apoptosis are implicated in gentamicin (GEN)-induced nephrotoxicity. Punicalagin (PNG) possesses antioxidant, anti-inflammatory, and antiapoptotic effects. Objective: The aim of the present research was to investigate the possible defensive effect of PNG against nephrotoxicity caused by GEN in male Sprague-Dawley rats. Materials and Methods: GEN (80 mg/kg/day, i.p.) was administered for 8 days. Treatment with PNG (25 mg/kg/day, p.o.) for 10 days, began 2 days before GEN insult. Results: PNG significantly decreased serum creatinine, and malondialdehyde, tumor necrosis factor-α, interleukin-6, inducible nitric oxide synthase, nuclear factor-κB p65 (NF- κB p65), and cleaved caspase-3 activity in the kidneys of GEN-challenged rats. PNG also significantly increased renal catalase, reduced glutathione, and nuclear factor erythroid 2-related factor 2 (Nrf2) in rats received GEN. Additionally, PNG markedly attenuated the histopathological kidney tissue injury caused by GEN. Conclusion: PNG guarded against GEN-induced kidney damage in rats through its antioxidant, anti-inflammatory, and antiapoptotic effects, and by modulating the balance between Nrf2 and NF-κB pathways.

Objective: This study aimed to analyze the anti-hyperglycemic activity of Torbangun leaf extract (TLE) in hyperglycemic rats by observing its effect on blood glucose levels and PEPCK and G6Pase gene expression. Method: This post-test-controlled group design study used a completely randomized design (CRD). Seven rats were separated as a normal group (N) and other rats were injected with streptozotocin (STZ). Hyperglycemia was characterized by fasting blood glucose (FBG) \>126 mg/dl. Hyperglycemic rats were divided into three groups: H-IM (control drug metformin hydrochloride dose 62.5 mg/kg BW), H-IT (TLE dose 620mg/kg BB), and NG (negative control, hyperglycemic rats). Rats were given intervention for 14 days. Result: The results showed a significant difference between initial and final FBG of the HI-IM group (p = 0.002, α = 0.01) and the H-IT group (p = 0.005, α = 0.01) and effect on the key gene expression of gluconeogenesis in the liver. The H-IT group showed a decrease in PEPCK gene expression 0.80 times and decreased G6Pase gene expression by 0.65 times compared to NG group. Conclusion: The findings suggested the administration of TLE in STZ-induced hyperglycemic rats was able to reduce blood sugar levels and was involved in inhibiting the expression of PEPCK and G6Pase expression genes in the liver.

In Morocco, Ziziphus lotus is commonly used as an urolithiatic agent in the traditional medicine. To confirm this effect, an aqueous extract of Ziziphus lotus (AEZL) has been studied in ethylene glycolinduced urolithiasis model of rats. 30 male rats were randomly divided into five groups of six animals each. Group I served as a vehicle control and received distilled water (0.5 ml/100 g p.o.). All remaining groups received calculi inducing treatment for 28 days, comprised of 0.75\% v/v ethylene glycol with 1\% w/v ammonium chloride in drinking water ad libitum for 3 days followed by only 0.75\% v/v ethylene glycol for 25 days. Group II served as lithiatic control and received distilled water (0.5 ml/100 g p.o.). Group III served as curative treatment group and received AEZL at doses of 150 mg/kg from 14th day to 28th day. Group VI served as preventive treatment group and received AEZL at doses of 150 mg/kg from 1st day to 28th day. Group V served as therapeutic and received a drug {\textquotedblleft}Cystone{\textquotedblright} at dose of 750 mg/kg from 14th day to 28th day. The extract treatment decreased the levels of oxalate and calcium in urine. Crystalluria analysis showed that untreated rats excreted large CaOx monohydrate and few dihydrate crystals while treated animals excreted mostly small CaOx dihydrate crystals. Significant similarity was observed between preventive and therapeutic anti-urolithiatic effect of AEZL and anti-urolithiatic effect of cystone (P\<0.001). These results demonstrated that AEZL have an anti-urolithiatic effect with preventive and therapeutic treatments in this experimental condition.

Introduction: Oxidative stress is one of the inflammatory events caused by obesity. This condition is characterized by an increase in various inflammatory markers, such as intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and a cluster of differentiation 40 (CD40). This study aimed to analyze the effect of Plectranthus amboinicus (Lour.) Spreng ethanol extract on ICAM-1, VCAM-1, and CD40 in obese rats. Methods: The study used a pure experimental method with a completely randomized design. There were 6 groups, namely, C- (negative control), C+ (positive control), CMC (soluble control), EE300 (P. amboinicus ethanol extract, 300 mg/kg body weight [BW]), EE600 (P. amboinicus ethanol extract, 600 mg/kg BW) and EE900 groups (P. amboinicus ethanol extract, 900 mg/kg BW). Results: The results showed low levels of ICAM-1 and VCAM-1 in the blood plasma, especially in the EE900 group, but the difference was not substantial. The same trend also occurred in the expression of CD40 in the tunica intima layer of the rat aorta. Conclusions: Thus, the administration of 900 mg/kg BW P. amboinicus ethanol extract for 45 days has the potential to treat obesity in rats through the suppression of oxidative stress and inflammatory markers (ICAM-1, VCAM-1 and CD40).

Background: Medicinal plants are a reservoir of biologically active compounds with therapeutic properties that, over time, have been used for the treatment of various diseases. This study aims to evaluate the protective effect of the aqueous extract of the leaves of Salvia officinalis against cypermethrin-induced toxicity. Methods: 30 male rats weighing approximately 240 g were divided into equal six groups; the control group received tap water, the positive control received the aqueous extract of sage leaves (SLE) at a dose of (0.5g/kg bw), the groups treated with cypermethrin (Cyp1) at 8.33 mg/kg bw and (Cyp2) at 25 mg/kg bw, and the groups treated by cypermethrin combined with aqueous extract of sage SLE+Cyp1 (0.5g/kg bw+8.33 mg/kg bw) and SLE+Cyp2 (0.5g/kg bw+25 mg/kg bw) for four days/week. After 4 weeks of oral administration, epididymal seminal fluid was analyzed via the CASA system, in addition to the histological study testis and epididymis. Results: The obtained results showed a decrease in the absolute weight of the reproductive organs, with a significant decrease in sperm concentration, motility and speed in the cypermethrin-treated group compared to the control. Histological study of the testes and epididymis indicates an alteration in the stages of spermatogenesis in groups Cyp1 and Cyp2 compared to the control. However, the above-mentioned parameters were maintained almost normal in the groups that received the aqueous extract of sage with both doses of cypermethrin. Conclusion: it can be demonstrated that SLE has been shown to protect rats from cypermethrin-induced reprotoxicity.

Introduction: PCOS is a hormonal disorder with missed or irregular periods at the reproductive ages of women, which was mainly due to increased androgen levels. Objective: To evaluate the antiandrogen activity of EEBL (ethanolic extract of betel leaf) in DHEA induced PCOS (polycystic ovary syndrome) and improving ovulation rate, consequently its effects on hormonal and biochemical profile of the blood serum and Histopathology of the ovary. Methods: Divide the 30 immature (4-week-old) female Sprague Dawley rats into 5 groups. Four groups except the control group were injected each morning with dehydroepiandrosterone (DHEA) (6 mg/100 g body weight/0.2 ml sesame oil) for 20days. The control group was injected with 0.2ml sesame oil for 20days. Pretreatment completed after 21st day then animals are subjected to posttreatment with EEBL (LD-100, HD-200mg/kg, p.o) and CC (100 μg/kg, p.o) from 21 to 41 days. After the treatment animals are subjected to biochemical, hormonal and histopathological examinations. Results: In negative control group SOD, Catalase were decreased. Total protein, SGOT, SGPT, TG, LDL and cholesterol levels were increased than the control group. Hormones LH and Testosterone levels increased. FSH, estradiol, and progesterone levels were decreased when compared with the control group. Histopathology has revealed that the presence of cysts in the negative control group and recovery of cysts seen in treatment groups. Conclusion: Treatment with EEBL is effectively attenuated to the DHEA induced PCOS and it is significant in comparison results with clomiphene citrate attributing its therapeutic potential towards the treatment of PCOS.

Aim/Background: Rural and Urban dwellers in Nigeria claim to treat their arthritis with Olax subscorpioidea root extracts. One of the reasons they chose this treatment is that it is effective and cost less than orthodox drugs with their accompanying side effects. Hence the aim of this study is to investigate the anti-arthritis effects of Olax subscorpioidea Afzel ethanol and aqueous root extracts on chicken type II-Complete Freund{\textquoteright}s adjuvant (CFA) induced arthritis rat model. Materials and Method: The anti-arthritic potential of ethanol and aqueous root extracts of Olax subscorpioidea was evaluated using the chicken type II-Complete Freund{\textquoteright}s adjuvant model in 135 female wistar albino rats. The rats were treated with aqueous and ethanol root extracts of Olax subscorpioidea at varying doses and standard indomethacine drug. Results: The ethanol and aqueous root extracts of Olax subscorpioidea showed significant anti-arthritic activity that was statistically similar to that of indomethacine. Our results suggest that the alcoholic extract of Olax subscorpioidea showed significant (P\<0.05) anti-arthritic potential.

Introduction: Sleep disorder may have detrimental consequences on health and one of the treatments is the use of hypnotics. Unfortunately, hypnotics treatment may also be accompanied by side effects and lead to dependence. The present study aimed to investigate the sleep improving effects of ethanol extract of Gardenia augusta (L.) Merr. flowers in rat model. Methods: Rats were assigned into group receiving the extract (at 0.9 or 1.8 g/kg), the reference drug crocetin (at 0.9 mg/kg) or vehicle, once a day orally for 15 days. Results: Tested on day 1 and 14 of treatment, the rats receiving 1.8 g/kg of the extract showed improvements in sleep latency, sleep duration, sleep efficiency, wake episodes, and sleep cycle, which were significantly different from crocetin. Furthermore, tested on day 2 and 15 of treatment, the rats treated with 1.8 g/kg extract demonstrated superior sedative rating scale compared to crocetin. Conclusions: Results of the present study indicates the potential of Gardenia augusta (L.) Merr. flower extract to be used as an adjunct treatment for sleep disorder.

Background: Plant extracts are generally assumed to be more acceptable and less hazardous than synthetic compounds and could be alternative antidiabetic treatments. Portula caoleracea has been used as one of the traditional edible and medicinal plant in Algeria to treat diabetes. The aim of the present study was to determine the effects of lyophilized aqueous extract of Portulaca oleracea on high-density lipoproteins composition, paraoxonase (PON1) and lecithin:cholesterol acyltransferase (LCAT) activities in streptozotocin-induced diabetic rat. Methods: Diabetes was induced intraperitonially by a single injection of streptozotocin (STZ) (60mg/kg bw). Twelve diabetic rats, weighing 263\±5g, were divided into two groups fed a casein diet supplemented or not with Portulaca oleracea extract (1g/kg bw), for 4 weeks. Results: At d28, in Portulaca oleracea treated vs untreated diabetic group, glycemia, serum total cholesterol (TC), triacylglycerols (TG) and phospholipids (PL) concentrations were decreased significantly (p\<0.05). The hypolipidemic effect induced by Portulaca oleracea extract was due to the reduction of total cholesterol (TC) in LDL-HDL1 (-51\%) and C-HDL3 (-21\%). Portulaca oleracea treatment improved PON1 and LCAT activities by 48\%. HDL3-UC (acyl group acceptor) and -PL (enzyme substrate) were diminished respectively by 47\% and 82\%, whereas HDL2-CE concentrations (product of LCAT reaction) were increased by 44\%. Moreover, HDL-C levels were found to be positively correlated with PON1 activity (r=0.96, p\<0.05). Serum, LDL-HDL1, HDL2 and HDL3 TBARS levels were respectively, 2.9-, 2.6-, 2.4- and 2.8-fold lower in Portulaca oleracea treated than untreated diabetic groups. Conclusion: These findings reflect the potential antihyperglycemic and hypolipidemic of Portulaca oleracea extract, in STZ-induced diabetic rat. Moreover, Portulaca oleracea extract restores PON1 and ameliorates the reverse cholesterol transport (RCT) by enhancing LCAT activity, therefore could prevent many diabetic complications by reducing dyslipidemia and oxidative damage.
