The consumption of prebiotics is known to affect the balance of gut microbiota. The purpose of this study was to explore how a galactomannan-rich effervescent drink can affect the population of Lactobacillus, Bifidobacterium, E. coli, and the concentration of short-chain fatty acids in the cecum of rats. Twenty-eight male Wistar rats (aged 2 months) were divided equally into 7 groups and treated orally each day for 15 days with 2 mL effervescent drinks with increasing levels of prebiotic galactomannan. The dosage of 500 mg galactomannan increased the growth of Lactobacillus spp. and Bifidobacterium spp. with inhibition of the growth of E.coli with increased formation of short-chain fatty acids such as acetate, propionate, and butyrate in the cecum of rats.

Abstract Background Benign prostatic hyperplasia (BPH) is a common disease which causes various health problems for elderly men such as urinary retention, recurring urinary tract infection and bladder stones. The aim of this study is to evaluate the therapeutic effects of Juniperus communis L. seed extract (JCS) on BPH in male Wistar rats. Methods To this end, 30 rats were divided into 5 groups (N = 6): group 1 (vehicle), group 2 (disease control), group 3 (standard medicine; 10 mg/kg finasteride), and groups 4 and 5 were treated with 300 mg/kg and 600 mg/kg of the hydroalcoholic JCS seed extract, respectively. Groups 2, 3, 4 and 5 received testosterone enanthate to induce prostatic hyperplasia. At the end of experimental period (28 days), prostate glands were cut off under anesthesia. Histopathological examination was done and biochemical parameters such as Malondialdehyde, Glutathione and protein carbonyl were also measured. Their body weights were also observed during the study. At the end of the experiment, prostate weights and prostate specific antigen (PSA) levels were measured. Prostate index, inhibition prostate weight and inhibition prostate index were also calculated. Results Both histopathological examination and biochemical parameter results showed significant improvements in rats treated with finasteride and 600 mg/kg JCS extract (p < 0.01). In addition, PSA levels showed significant decrease in comparison with the disease group. But acute toxicity test indicated that using JCS extract resulted in an increase in liver enzymes (ALP, LDH, SGOT, SGPT). As a result, the extract should be used with caution. Conclusions Oral administration of JCS extract is effective on preventing testosterone-induced benign prostatic hyperplasia.

Aging is one of the major risk factors for suffering cardiovascular and metabolic diseases. Due to the increase in life expectancy, there is a strong interest in the search for anti-aging strategies to treat and prevent these aging-induced disorders. Both omega 3 polyunsaturated fatty acids (ω-3 PUFA) and extra virgin olive oil (EVOO) exert numerous metabolic and cardiovascular benefits in the elderly. In addition, EVOO constitutes an interesting ingredient to stabilize ω-3 PUFA and decrease their oxidation process due to its high content in antioxidant compounds. ω-3 PUFA are commonly obtained from fish. However, more ecological and sustainable sources, such as algae oil (AO) can also be used. In this study, we aimed to study the possible beneficial effect of an oil mixture composed by EVOO (75%) and AO (25%) rich in ω-3 PUFA (35% docosahexaenoic acid (DHA) and 20% eicosapentaenoic acid (EPA)) on the cardiometabolic alterations associated with aging. For this purpose; young (three months old) and old (24 months old) male Wistar rats were treated with vehicle or with the oil mixture (2.5 mL/kg) for 21 days. Treatment with the oil mixture prevented the aging-induced increase in the serum levels of saturated fatty acids (SFA) and the aging-induced decrease in the serum concentrations of mono-unsaturated fatty acids (MUFA). Old treated rats showed increased serum concentrations of EPA and DHA and decreased HOMA-IR index and circulating levels of total cholesterol, insulin and IL-6. Treatment with the oil mixture increased the mRNA levels of antioxidant and insulin sensitivity-related enzymes, as well as reduced the gene expression of pro-inflammatory markers in the liver and in cardiac and aortic tissues. In addition, the treatment also prevented the aging-induced endothelial dysfunction and vascular insulin resistance through activation of the PI3K/Akt pathway. Moreover, aortic rings from old rats treated with the oil mixture showed a decreased response to the vasoconstrictor AngII. In conclusion, treatment with a mixture of EVOO and AO improves the lipid profile, insulin sensitivity and vascular function in aged rats and decreases aging-induced inflammation and oxidative stress in the liver, and in the cardiovascular system. Thus, it could be an interesting strategy to deal with cardiometabolic alterations associated with aging.

BACKGROUND<br />Non-alcoholic steatohepatitis (NASH) is a chronic liver disease associated with increased free fatty acids, trans fatty acids and free radical compounds due to the consumption of deep frying oil (DFO). Ginger has hypolipidemic and antioxidant properties, and acts as an insulin sensitizer. The present study was conducted to evaluate the hepatoprotective effect of an ethanol extract of Zingiber officinale Roxb var rubrum (EEZO) in DFO-fed male Wistar rats.<br /><br />METHODS<br />A study of experimental design was conducted involving 24 non-alcoholic steatohepatitis (NASH) male Wistar rats that were randomly divided into 4 groups. Group K1 (control) was given DFO-3 (3 times heated DFO) at a dose of 10 ìl/g BW/day. The treatment groups (P1, P2, P3) were given DFO-3 and red ginger rhizome extract at doses of 100, 200, and 400 mg/kg BW orally for 30 days. The histopathology examination assessed fatty degeneration, and degree of fibrosis. The data were analyzed with the Kruskal-Wallis and Mann-whitney test.<br /><br />RESULTS    <br />The Kruskal-Wallis test showed that fatty degeneration (steatosis, lobular inflammation, hepatocyte ballooning and NASH) were significantly different among the four groups (p&lt;0.05). Mann-Whitney test proved that fatty degeneration was not significantly different between control and treatment groups (p&gt;0.05).<br /><br />CONCLUSION<br />Deep frying oil increased fatty degeneration and NASH, and none of red ginger rhizome extract doses was able to inhibit fatty degeneration significantly. For the future research it is intended to prolong the induction time and the administration of red ginger rhizome extract.

Honey is consumed as food and also used in the treatments of ailment. However, honey of various types exhibit varying properties. Their therapeutic effects are determined by whether the honey is multifloral or monofloral, and also on the variety of nectars the honey is derived from. Manuka and Tualang types of honey were observed to possess anti-ulcer effects. However, no such report is available for University of Ilorin honey. This study therefore aimed to determine the gastroprotective effects of University of Ilorin honey in Wistar rats using two laboratory models for inducing ulcer (HCl/Ethanol and Indomethacin). Twenty rats each were assigned to four groups for each model of ulcer. The rats were treated for 12 days with the administration of distilled water (control), cimetidine (100 mg/kg b.w.) and University of Ilorin honey (250 mg/kg b.w. in one group and 1000 mg/kg b.w in another group). The rats were fasted for 24 hours after the last treatment. Then, the ulcerogens were given orally. After four hours, the rats were sacrificed, gastric juice was collected and the stomachs were examined for ulceration. The results revealed that pre-treatment with University of Ilorin honey reduced gastric index from 6.80±0.20 (1000 mg/kg b.w. to 2.40±0.24 (control) P<0.05 and 7.20±0.37 (1000 mg/kg b.w.) to 3.20±0.37 (control) P<0.05 in HCl/Ethanol and indomethacin induced ulcer models respectively. There was no significant difference in ulcer index between the cimetidine administered rats and the honey administered group (1000 mg/kg bw.), but the honey group (250 mg/kg bw.) was less effective than the cimetidine group in the models used. Also, there were no changes in gastric acidity in all the groups compared with the control group. In conclusion, the results showed that University of Ilorin honey has protective effect on the gastrointestinal tract which is not due to alteration of gastric acidity.

We evaluated the effects of partly substituting lard with marine n-3 fatty acids (FA) on body composition and weight, adipose tissue distribution and gene expression in five adipose depots of male Wistar rats fed a high-fat diet. Rats were fed diets including lard (19·5 % lard) or n-3 FA (9·1 % lard and 10·4 % Triomar™) for 7 weeks. Feed consumption and weight gain were similar, whereas plasma lipid concentrations were lower in the n-3 FA group. Magnetic resonance imaging revealed smaller visceral (mesenteric, perirenal and epididymal) adipose depots in the n-3 FA-fed animals (35, 44 and 32 % reductions, respectively). n-3 FA feeding increased mRNA expression of cytokines as well as chemokines in several adipose depots. Expression of Adipoq and Pparg was enhanced in the mesenteric adipose depots of the n-3 FA-fed rats, and fasting plasma insulin levels were lowered. Expression of the lipogenic enzymes Acaca and Fasn was increased in the visceral adipose depots, whereas Dgat1 was reduced in the perirenal and epididymal depots. Cpt2 mRNA expression was almost doubled in the mesenteric depot and liver. Carcass analyses showed similar body fat (%) in the two feeding groups, indicating that n-3 FA feeding led to redistribution of fat away from the visceral compartment.
