Introduction. Benign prostatic hyperplasia (BPH) is a common urological disorder in older men. It is characterized by the development of glandularstromal hyperplasia of the prostate with the formation of new glandular structures and subsequent symptoms from the lower urinary tract. It has now been established that the pathogenesis of this disease is multifactorial and one of the possible mechanisms for the development of BPH is oxidative stress. Purpose. Study of the effect of phenols with a bulky isobornyl substituent (2,6-diisobornyl-4-methylphenol and 4-hydroxymethyl-2,6-diisobornylphenol)on the growth of experimental BPH and the antioxidant balance of prostate cells in comparison with Prostamol Uno. Materials and мethods. Experiments were carried out on 50 male Wistar rats. BPH was caused by daily administration of sulpiride (60 days) to male rats of late reproductive age. After 2 months, the animals were weighed and sacrificed in a CO2 chamber. The mass, mass coefficient, volume of the lateral lobe of the pancreas were determined, morphological analysis was performed. Investigated prooxidant and antioxidant activity. The results were processed by the method of variation statistics using the Mann-Whitney nonparametric U test. Results. The efficacy of the investigated drugs in BPH decreased in the following sequence: sulpiride + substance 4-hydroxymethyl-2,6-diisobornylphenol (HDB) → sulpiride + substance Dibornol (DB) → sulpiride + Prostamol Uno (PU). When comparing the results of evaluating the anti-prooxidant status with the therapeutic effect of the studied drugs, it was found that isobornylphenols, which are highly effective as prostatotropic drugs, did not show a more significant effect, compared to PU, on the redox potential of prostatic tissue cells. Conclusions. Drugs DB, HDB, PU have a normalizing effect on the level of severity of redox reactions in the sulpiride model of BPH.

The sufferers of Diabetes Mellitus (DM) in Indonesia is the highest with fourth number in the world, with a mortality rate of 1.2 million in 2012. Because of it, DM research using antihyperglycemic green tea is needed. This study aims to determine the effectiveness of green tea extracts on decreasing fasting blood glucose (KGDP) levels in alloxan-induced white male Wistar rats. Samples were 30 male rats, aged 8-12 weeks, weight ± 200 grams. Rats were grouped into 6 groups with the first group (K1) as a control, the second group (K2) induced alloxan, the third group (K3) induced alloxan with glibenclamide, the fourth group (K4), the fifth group (K5), and the sixth group (K6) induced alloxan with green tea extract as the treatment with dose of green tea extract, 200 mg/kg, 400 mg/kg, and 800 mg/kg. The first, FBG level examination is done 3 days after induction of alloxan using a glucometer. Giving green tea extract was given for 16 days orally, then FBG level re-examined from the tail of rats. One Way ANOVA Test Results, there is the effectiveness of green tea extract on reducing FBG level (p = 0,000). The post hoc Bonferroni test showed that giving 800 mg/kg of green tea extract was the best dose in reducing KGDP close to normal (p = 0,000).

This study was aimed at investigating the cytoprotective activities of Curcuma longa (Turmeric) on the histological structure of the testes in diabetic male rats. Turmeric is commonly called the golden spice, is used as a spice in cooking and also has a long history of medicinal use, dating back nearly 4000 years to the Vedic culture in India. Its major component is the curcumin that is found to be a natural antioxidant. Diabetes affects large number of young men of reproductive age. It is among a number of disorders associated with oxidative stress. There has been a relationship established between the reduction in glucose load and insulin resistance reduction and oxidative stress in people. Male wistar rats (n=24) were allocated randomly into six groups, 4 in each. Group 1: Control were given only water and standard rat chow; Group 2 and 3: turmeric (100mg/kg) and (25mg/kg) respectively; Group 4: induced with 30mg/kg of streptozotocin (STZ) for 3 days; Group 5: STZ with turmeric (100mg/kg); Group 6: STZ with turmeric (25mg/kg). At the end of the experiment (21 days), the testes were excised for histological analysis. The seminiferous tubules, seminiferous epithelium, Leydig cells were shown to be enhanced in the histoarchitecture of the testes of the treated diabetic groups and did not show any toxicity on the testes in the non-diabetic groups. In conclusion, this study has shown that turmeric does not only possess a non-toxic effect but has cytoprotective effects on the histoarchitecture of the testes in diabetic rats.Keywords: histo-architecture, leydig cells, diabetes, oxidative stress, testes, curcumin.

Abstract. Alterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows ( n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 ± 0.41% and 6.28 ± 1.03% respectively, p < 0.05) and rearing frequency (2.75 ± 0.41 and 3.85 ± 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 ± 5.87 s and 44.92 ± 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 ± 0.49%, 5.37 ± 0.44 and 15.3 ± 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 ± 0.1 ppm, p < 0.001), magnesium (170.4 ± 1.7 ppm, p < 0.005) and phosphate (2.76 ± 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 ± 0.16 ppm, 179.31 ± 1.87 ppm and 3.11 ± 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 ± 1.87 ppm, p < 0.05), phosphate (2.44 ± 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 ± 5.76 ppb, p < 0.001) and copper (2.79 ± 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 ± 1.87 ppm, 3.11 ± 0.06 ppm, 327.25 ± 8.35 ppb and 2.45 ± 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.

The incorporation of cisplatin (CP) as a cytotoxic antineoplastic agent in most chemotherapeutic protocols is a challenge due to its toxic effect on testicular tissues. Natural compounds present a promising trend in research, so a new nutraceutical formulation (NCF) was designed to diminish CP spermatotoxicity. A combination of three nutraceutical materials, 250 mg Spirulina platensis powder (SP), 25 mg Tribulus terrestris L. extract (TT), and 100 mg fish oil (FO) were formulated in self-nanoemulsifying self-nanosuspension (SNESNS). SP was loaded into the optimized self-nanoemulsifying system (30% FO, 50% span 80/cremophor EL and 20% isopropanol) and mixed with TT aqueous solution to form SNESNS. For the SP, phytochemical profiling revealed the presence of valuable amounts of fatty acids (FAs), amino acids, flavonoids, polyphenols, vitamins, and minerals. Transmission electron microscopy (TEM) and particle size analysis confirmed the formation of nanoemulsion-based nanosuspension upon dilution. Method validation of the phytochemical constituents in NCF has been developed. Furthermore, NCF was biologically evaluated on male Wistar rats and revealed the improvement of spermatozoa, histopathological features, and biochemical markers over the CP and each ingredient group. Our findings suggest the potential of NCF with SNESNS as a delivery system against CP-induced testicular toxicity in male rats.

Abstract Background Tramadol is a widely used synthetic opioid. Substantial research has previously focused on the neurological effects of this drug, while the efficacy of various treatments to reduce the associated side effects has not been well studied. This study aimed to evaluate the protective effects of naloxone, diazepam, and quercetin on tramadol overdose-induced seizure and sedation level in male rats. Methods The project was performed with 72 male Wistar rats with an average weight of 200–250 g. The rats were randomly assigned to eight groups. Tramadol was administered intraperitoneally at an initial dose of 25 mg/kg/day. On the 14th day, tramadol was injected at 75 mg/kg, either alone or together with naloxone, diazepam, and quercetin (acute and chronic) individually or in combination. The rats were monitored for 6 h on the last day, and the number, the duration, and the severity of seizures (using the criteria of Racine) were measured over a 6-h observation period. The sedation level was also assessed based on a 4-point criterion, ranging from 0 to 3. Data were analyzed in SPSS software using Kruskal–Wallis, Chi-square, regression analysis, and generalized estimating equation (GEE) tests. The significance level was set at P < 0.05. Results The naloxone-diazepam combination reduced the number, severity, and cumulative duration of seizures compared to tramadol use alone and reduced the number of higher-intensity seizures (level 3, 4) to a greater extent than other treatments. Naloxone alone reduced the number and duration of seizures but increased the number of mild seizures (level 2). Diazepam decreased the severity and duration of seizures. However, it increased the number of mild seizures (level 2). In comparison with the tramadol alone group, the acute quercetin group exhibited higher numbers of mild (level 2) and moderate (level 3) seizures. Chronic quercetin administration significantly increased the number of mild seizures. In the GEE model, all groups had higher sedation levels than the saline only group (P < 0.001). None of the protocols had a significant effect on sedation levels compared to the tramadol group. Conclusion The combined administration of naloxone and diazepam in acute-on-chronic tramadol poisoning can effectively reduce most seizure variables compared to tramadol use alone. However, none of the treatments improved sedation levels.

Background. There is a gender disparity in the incidence, prevalence, and progression of renal disease. The object of this paper is to evaluate the presence and type of renal lesion in normogonadic and hypogonadic male rats in a mild hyperuricemia induced condition and exposed to a high-fructose diet. Methods. 56 adult male Wistar rats were used. Animals were divided into two groups, one normogonadic (NGN) and one hypogonadic (HGN), and each group was divided into four subgroups in accordance with the treatment: control with only water (C), fructose (F), oxonic acid (OA), and fructose + oxonic acid (FOA). Renal changes were evaluated by measuring glomerulosclerosis, fibrosis, and arteriolar media/lumen (M/L) ratio.Results. The OA and FOA groups presented significantly hypertension (p<0.001). The OA group significantly increased (p<0.05) the percentage of glomerulosclerosis as well as the FOA group (p<0.001). When comparing NGN versus HGN, we observed a trend to a lower glomerulosclerosis in the latter. A higher arteriolar M/L ratio was observed in the OA (p<0.05) and FOA (p<0.001). Conclusion. Hyperuricemia conditions and a high-fructose diet favor blood pressure increase together with changes in the arteriolar media/lumen ratio and renal glomerular damage. These changes were more apparent in normogonadic animals.

Female and male Wistar rats were used to determine the subchronic oral toxicities of two new ethyl-carbamates with ixodicidal activities (ethyl-4-bromphenyl-carbamate and ethyl-4-chlorphenyl-carbamate). The evaluated carbamates were administered in the drinking water (12.5, 25 and 50 mg/kg/day) for 90 days. Exposure to the evaluated carbamates did not cause mortality or clinical signs and did not affect food consumption or weight gain. However, exposure to these carbamates produced alterations in water consumption, hematocrit, percentages of reticulocytes, plasma proteins, some biochemical parameters (aspartate aminotransferase, gamma-glutamyl transpeptidase, cholinesterase, and creatinine activities), thiobarbituric acid reactive substances, and the relative weight of the spleen. Histologically, slight pathological alterations were found in the liver that were consistent with the observed biochemical alterations. The nonobserved adverse effect levels (NOAELs) of the evaluated carbamates were 12.5 mg/kg/day for both the female and male rats. The low severity and reversibility of the majority of the observed alterations suggest that the evaluated carbamates have low subchronic toxicity.

Abstract Exercise counteracts obesity effects, but information on how early-life obesity may affect long-term adaptation to exercise is lacking. This study investigates the impact of early-life postnatal overfeeding (PO) on animals’ adaptation to exercise. Only male Wistar rats were used. On postnatal day (PN) 30, rats from control (NL-9 pups) or PO (SL-3 pups) litters were separated into four groups: NL-sedentary (NL-Se), NL-exercised (NL-Ex), SL-sedentary (SL-Se), and SL-exercised (SL-Ex). Exercised groups performed moderate-intensity exercise, running on a treadmill, from PN30 to PN90. Further experiments were carried out between PN90 and PN92. PO promoted obesity in SL versus NL rats (P < 0.05). Exercise reduced body weight (P < 0.001), body fat (P < 0.01), and improved glucose homeostasis in SL-Ex versus SL-Se. SL-Ex presented lower VO2max (P < 0.01) and higher post-exercise LDH (P < 0.05) compared to NL-Ex rats. Although moderate exercise counteracted obesity in SL rats, early-life overnutrition restricts fitness gains in adulthood, indicating that early obesity may impair animals’ adaptation to exercise.

Cadmium (Cd) is widespread in the environment. Cd toxicity targets liver and renal tissues and generates oxidative stress. Medicinal plants produce antioxidants scavenging reactive oxygen species (ROS) and chelate heavy metals. This study aimed to investigate the preventive effects of Myrtus communis leaves hydro-methanol extract (HME) and aqueous extract (AE) on Cdinduced toxicity. The experiments were carried out, during 30 days, on male rats; GR1 (controls), GR2 treated with CdCl2 (18 mg/kg), GR3 co-treated with HME (1 g/kg) and Cd (18 mg/kg), GR4 co-treated with AE (1 g/kg) and Cd (18 mg/kg), GR5 with HME and GR6 with AE. Cd induced changes in biochemical parameters (transaminases, urea, creatinine and blood sugar)related to hepato renal function, increased tissue mortification and decreased animals’ body weight. While the treatment animals, with M. communis leaves (HME) or (AE), regulated blood sugar levels. Hepatic steatosis and loss of glomeruli were particularly induced either by Cd or a co-treatment with Cd and plant extracts. M. communis extracts (HME and EA) can regulate blood sugar levels and prevent cadmium accumulation.

Benign phyllodes tumour (BPT) of the prostate is a very rare neoplasm. It is composed of hyperplastic and neoplastic glandular stromal proliferation. Patients with BPT of the prostate generally present with lower urinary tract symptoms and hematuria. BPT of the prostate can potentially cause recurrent obstructive symptoms. Complete transurethral resection (TUR) and close postoperative follow-up is recommended. A 59-year-old man presented with dysuria and obstructive urinary symptoms. Flexible cystoscopy revealed prostatic hyperplasia and a polypoidal lesion originating from the right lateral lobe of the prostate. Magnetic resonance imaging revealed a 3 × 2.5-cm mass lesion in the right lateral lobe of the prostate. TUR of the prostate was performed and the pathological examination revealed benign prostatic hyperplasia and benign phyllodes tumour of the prostate.
