Pak-wanban (Sauropus androgynus L. Merr.), a popular Thai vegetable, has been found to have a high content of Coenzyme Q10 (CoQ10), which is a powerful antioxidant. This study investigated the quantitation, absorption and tissue distribution of CoQ10 from raw and stir-fried Pak-wanban and its antioxidant activities in rats. Male Wistar rats (seven weeks old) were randomly grouped as follows: (1) control, (2) raw Pak-wanban powder of 0.5 mg CoQ10/kg/day, (3) stir-fried Pak-wanban powder of 0.5 mg CoQ10/kg/day, (4) stir-fried Pak-wanban powder of 1.0 mg CoQ10/kg/day, and (5) commercially CoQ10 supplement groups of 0.5 mg CoQ10/kg/day. The results found that stir-fried cooking did not significantly reduce the content of CoQ10 in the Pak-wanban leaves. After 3 weeks of experimentation, the level of CoQ10 in the plasma, liver and spleen was increased in all Pak-wanban groups when compared to the control group. The level of CoQ10 in the stir-fried Pak-wanban group was significantly higher than the raw Pak-wanban group but slightly lower than the CoQ10 supplement group.  Liver alpha-tocopherol concentrations were markedly increased in rats that consumed a high dose of CoQ10 from stir-fried Pak-wanban of 1 mg of CoQ10/kg/day when compared with the control group. Plasma antioxidant activities (ORAC: FRAP: DPPH) were significantly increased in both groups of stir-fried Pak-wanban when compared with the control group. We concluded that CoQ10 in  Pak-wanban could be well absorbed and improved the plasma antioxidant activities. Furthermore, cooking oil may increase the bioavailability of CoQ10 from vegetables. Therefore, it would be useful for vegetarian people.

This study explores the antiskin cancer effect of formulated agar (FA) from Laminaria digitata on dimethyl benzanthracene- (DMBA-) induced skin cancer mice. The agar was extracted and formulated (emulgel), and FA was biochemically characterized. The in vitro cytotoxicity of FA was tested using NTT 3T3 mice fibroblast cells. The mice were divided into 5 groups: group 1 served as control mice, group 2 mice were considered as DMBA-induced cancer control, group 3 mice were FA pretreated (low dose) + DMBA-induced mice, group 4 mice were FA pretreated (high dose) + DMBA-induced mice, and group 5 were positive control + DMBA-induced mice. The behaviour and biochemical markers of cancer were significantly decreased in group 2 (DMBA-induced) mice, which were brought to near normalcy by FA pretreated mice (groups 3 and 4). The levels of p53 and keratin were significantly elevated in group 2 mice and these levels were decreased in 3 and 4 mice as well. The histopathological examination of DMBA-induced mice was shown degenerated cervical patches in the skin, cirrhosis in liver, oedema in the renal tissue, and swollen and damage in cardiac tissue, which were reduced for the mice applied with FA. This confirms that FA pretreatment offered potential antiskin cancer property.

Hepatoprotective and antioxidant activity of Lannea coromandelica bark extract (LCBE) was investigated on thioacetamide induced hepatotoxicity in rats. Hepatotoxicity was induced by thioacetamide (TAA) administration (100 mg/kg. s.c). LCBE at different doses (400 and 200 mg/kg) were administered orally to male wistar rats. Thioacetamide caused elevation of serum concentration of AST, ALT, ALP, serum bilirubin and also reduced serum concentration of total protein, albumin, sodium, potassium in animals as compared to control (p < 0.05) but LCBE treated rats showed maximum reduction of AST [(138±5.1) IU/L], ALT [(71 ±2.7) IU/L], ALP [(140 ±1.9) IU/L] with the high dose (400 mg/kg bw) of combined aqueous and alcoholic bark extract. Whereas, serum bilurubin, cholesterol, sugar and LDH content were varied with the treatments but showed higher with the only ethanolic extract at dose of 400 mg/kg. The IC50 value was observed as (83.28 ±2.12) µg/mL, for DPPH radical scavenging activity. Result concluded that ethanolic extract and combined aqueous and alcoholic bark extract of L. coromandelica showed a potential hepatoprotective and antioxidant activities might be due to the presence of phenolic groups, terpenoids and alkaloids.

ABSTRACT Non-alcoholic fatty liver can be triggered by used cooking oil consumption due to the formation of free radicals and the accumulation of fatty acids in the body. Astaxanthin is a powerful antioxidant that may be able to inhibit the pathogenesis of fatty liver. This study aims to determine the effect of astaxanthin in inhibiting fatty liver (steatosis) and levels of Gamma-Glutamyltransferase (GGT) in male Wistar rats given used cooking oil. An experimental study with Post-test Only Control Group Design was conducted on 36 male Wistar rats aged 3.5-4 months with an approximate bodyweight of 200-210 grams divided randomly into 2 groups. The control group was given 0.42 ml of used cooking oil + 0.5 ml of distilled water, and the treatment group was given 0.42 ml of used cooking oil + 0.2 mg of astaxanthin each day for 14 days. On day 15, blood tests and hepatic histopathology were performed to check  GGT serum levels and steatosis. The comparative test was conducted to compare the results of the control and treatment groups. The results showed that the mean steatosis and GGT levels in the treatment group were significantly lower than the control group. It can be concluded that giving astaxanthin can inhibit fatty liver (steatosis) and increase GGT serum levels in male Wistar rats given used cooking oil.   Keywords: Astaxanthin, Fatty liver, Gamma-glutamyltransferase, Used cooking oil

Abstract Objective: To test the hypothesis that the administration of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone have no effect on root resorption and tooth movement. Materials and Methods: A mesial force of 50 g was applied to the left maxillary first molars of sixty 10-week-old male Wistar rats using nickel titanium closed coil springs attached to the cervical area of the incisors. The rats were randomly divided into 12 groups of 5 each. High and low doses of aspirin, acetaminophen, meloxicam, celecoxib, and prednisolone were administered via drinking water for 2 weeks. The experimental control group had tooth movement but received no drug. The negative control group received neither tooth movement nor drugs. The amount of tooth movement was measured on digitized lateral cephalometric radiographs. Rats were sacrificed after 2 weeks. Mesial and distal roots (distobuccal and distopalatal) were examined using scanning electron and three-dimensional (3D) scanning laser microscopes. The surface area, depth, volume, and roughness of the root resorption craters were measured. Results: When compared with experimental control rats, only prednisolone- and high-dose celecoxib-treated groups showed significantly less root resorption and less tooth movement. Although low dose celecoxib-treated group significantly decreased the tooth movement, root resorption was similar to the control group. Furthermore, resorption craters showed a smoother surface in the prednisolone-treated rats. Conclusions: The hypothesis was rejected. Administration of prednisolone and high-dose celecoxib reduces root resorption and interferes with tooth movement in rats. Both drugs may interfere in the arachidonic acid cascade depending on dose thresholds.

Monosodium glutamate (MSG) toxicity is fast becoming a global health challenge due to the increase in its consumption as a food additive. This study investigated the effect of consumption of MSG and treatment with graded doses of omega 3 fatty acids (ω-3). Forty-eight male Wistar rats (n=8) grouped into six; control, MSG, MSG + Low dose of ω-3 (LD ω-3); MSG + High dose of ω-3 (HD ω-3), LD ω-3, and HD ω-3 were used for this study. MSG was administered at 4 g/L/day in their drinking water for 6 weeks, while ω-3 was administered at low and high doses of 100 and 300 mg/kg BW, p.o. respectively for 4 weeks. Results revealed that administration of MSG induced imbalance in lipid metabolism, oxidative stress and hepatic dysfunction. These were revealed by significant decreases in TG, HDL-C, CAT, GSH, albumin and total protein; but, significant increases in LDL-C, MDA, AST, ALT, ALP, and total bilirubin (TB), compared to control group. Administration of graded doses of ω-3 following treatment with MSG was characterized with significant reductions in ALT, ALP, TB and MDA. The administration of ω-3 showed no effects on the antioxidant indices. Conclusively, LD ω-3 is a potent ameliorative supplement which can be administered after pre-exposure to MSG.

Hepatotoxicity caused by chemotherapeutic drugs (e.g., doxorubicin) is of critical concern in cancer therapy. This study focused on investigating the modulatory effects of diosmin against doxorubicin-induced hepatotoxicity in Male Wistar rats. Male Wistar rats were randomly divided into four groups: Group I was served as control, Group II was treated with doxorubicin (20 mg/kg, intraperitoneal, i.p.), Group III was treated with a combination of doxorubicin and low-dose diosmin (100 mg/kg orally), and Group IV was treated with a combination of doxorubicin and high-dose diosmin (200 mg/kg orally) supplementation. A single dose of doxorubicin (i.p.) caused hepatic impairment, as shown by increases in the concentrations of serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Doxorubicin produced histological abnormalities in the liver. In addition, a single injection of doxorubicin increased lipid peroxidation and reduced glutathione, catalase, and superoxide dismutase (SOD) levels. Importantly, pre-treatment with diosmin restored hepatic antioxidant factors and serum enzymatic activities and reduced the inflammatory and apoptotic-mediated proteins and genes. These findings demonstrate that diosmin has a protective effect against doxorubicin-induced hepatotoxicity.

The present study was conducted to investigate the antioxidant, histomorphometric, histochemical, immunohistochemical, biochemical, and cytological effects of coenzyme Q10 (CoQ10) against bisphenol-A (BPA)-induced testicular toxicity in rats. A total of 40 adult male Wistar rats were divided into five equal groups. The control group remained untreated. The vehicle control group was administered corn oil (2 ml/kg/day), the BPA group was given BPA (100 mg/kg/day), the CoQ10 group was supplemented with CoQ10 (10 mg/kg/day), and the rats in the CoQ10-BPA group received CoQ10 (10 mg/kg/day) followed by BPA (100 mg/kg/day) 1 h later. The treatments were administered by oral gavage for 14 days. Results showed that the seminiferous tubule diameters (STDs) and seminiferous epithelium heights (SEHs) at stages VII–VIII and XII–XIV, number of undifferentiated embryonic cell transcription factor-1 (UTF-1) positive cells per tubule, UTF-1 positive tubules (%), plasma glutathione (GSH), and serum superoxide dismutase activities, testicular GSH activity and sperm viability (%) decreased whereas the number of terminal dUTP nick end labeling (TUNEL) positive cells per tubule, TUNEL positive tubules (%), testicular and serum malondialdehyde (MDA) levels, and the rate of mid-piece sperm abnormality increased in the BPA administered group. However, while the STDs at stages VII–VIII and XII–XIV, SEHs at stages VII–VIII, plasma GSH, and serum SOD activities increased, serum MDA level decreased in the CoQ10-BPA group. In conclusion, these results suggest a protective effect of CoQ10 against BPA-induced testicular toxicity in rats.

Vitamin B12 (B12) is present in foods of animal origin, and vegans are encouraged to take supplements with synthetic B12 in order to ensure a sufficient uptake. Recent rat studies suggest that natural (hydroxo-B12, HO-B12) and synthetic (cyano-B12, CN-B12) B12 behave differently in the body. Here, we test if a daily vitamin pill matches dietary B12 in ability to restore a low B12 status in rats. B12-depleted male Wistar rats (n = 60) were divided into five groups (n = 12 in each) and subjected to two weeks intervention with various schemes of B12 supplementation. Two “dietary” groups received a low-B12 chow that was fortified with either HO-B12 or CN-B12 providing a continuous supply. Two “pill” groups received a single daily dose of CN-B12, where the vitamin content either matched or exceeded by factor four the provisions for the “dietary” groups. A control group received the low-B12 chow without B12 fortification. B12 was measured in plasma and tissues. Dietary B12 provides 35% more B12 to the tissues than an equivalent single daily dose (p < 0.0001). Natural B12 delivers 25% more B12 to the liver than synthetic B12 (p = 0.0007). A fourfold increase in B12, supplemented as a single daily dose, does not provide any extra B12 to the tissues (p = 0.45). We conclude that dietary B12 is better at rescuing a low B12 status than a daily vitamin pill.

Introduction: Methotrexate (Met) as a chemotherapy drug has many side effects, such as infiltration of neutrophils and development of oxidative stress. Crocin (Cro), a carotenoid isolated from saffron, has numerous therapeutic characteristics including anticancer and antioxidant activities. This study was designed to evaluate the effects of Cro against hepatic damage in rats induced by Met. Methods: In this study, 48 male Wistar rats were randomly assigned into 8 groups, control normal (saline), Met control-treated group (20 mg/kg), Cro groups (12.5, 25, 50 mg/kg) and Met + Cro treated groups (12.5, 25, 50 mg/kg). Treatments were administered by intraperitoneal injection daily for 28 days. Griess technique was hired for the determination of serum nitrite oxide (NO) level. Concentrations of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were determined in order to assess liver function disturbances. In addition, Thiobarbituric acid reactive species, antioxidant capacity, diameter of hepatocytes and central hepatic vein (CHV) were investigated. Results: Met administration significantly increased the liver malondialdehyde (MDA) and NO level, the mean diameter of CHV, hepatocytes and hepatic enzymes. Met also decreased the tissue FRAP level compared to the normal control group (P < 0.01). The Cro and Cro + Met treatments in all doses significantly reduced the mean diameter of hepatocytes and CHV, hepatic enzymes, hepatic MDA and NO levels and increased the tissue FRAP level compared to the Met control group (P < 0.01). Conclusion: It seems that Cro administration improves liver injury induced by Met in rats.

Ganoderma lucidum polysaccharides (GLPs) are commonly used as health-promoting medicine and dietary supplement due to the positive effects in immune modulation, antitumor and antioxidant activities. However, whether GLPs executes other uncharacterized effects is largely unclear. The rats were pre-primed with GLPs and then administrated with canonical “cocktail probes” of cytochrome P450 (CYP450) isozymes including caffeine, tolbutamide, dextromethorphan, omeprazole, and midazolam. The plasma concentrations of probes at each indicated time point were simultaneously detected using the designed high-performance liquid chromatography-tandem mass spectrometric (LC-MS/MS) method. The results suggested that GLPs could increase the accumulated levels of caffeine, tolbutamide and midazolam in plasma as compared to control group. Besides, GLPs reduced the concentration of dextromethorphan in blood at high dose, while elevated it at low dose. GLPs could inhibit the activities of CYP1A2, and CYP3A4, additionally; GLPs at low dose suppressed the activity of CYP2D6, which demonstrated that drugs co-administrated with GLPs might require strictly evaluating the dose relation.
