214 Background: In our preliminary in vitro studies, we have demonstrated evidence of enhanced apoptosis and inhibition of cellular proliferation in both hormone sensitive and castrate resistant prostate cancer (PCa) cell lines using a combination of an antiandrogen (Bicalutamide) and a selective estrogen receptor modulator (Raloxifene). The aim of this study was to study the effect of the administration of these two drugs in in vivo models of castrate resistant PCa. Methods: In vivo model consisted on NCr Nude: Mice bearing s.c. human prostate (PC3 cell line) xenografts. Based on the treatment received, mice were divided into 5 groups as follows: Group 1: No drugs (control); Group 2: Bicalutamide 50mg; Group 3: Raloxifene 60 mg; Group 4: Combined administration of Bicalutamide 50 mg and Raloxifene 60 mg; Group 5 Combined administration of Bicalutamide 150 mg and Raloxifene 120 mg. A total of 10 mice where included in each group. All drugs dosages were converted to their equivalent in the mice. Drugs were administered by gavage technique to the mice once per day for a total of 14 days. Results: As expected, Bicalutamide administered alone causes minimal inhibition without reaching statistical significance (Group 2: 0.34 g Vs Group 1: 0.40 g; p=0.073). Although Raloxifene causes some marked growth inhibition, its effect is not statistically significant (Group 3: 0.31 Vs Group 1: 0.40 g; p=0.062). Bicalutamide and Raloxifene, when administered in combination, induced prominent growth inhibition in PC3 tumors when compared to the control group (Group 4: 0.26 g Vs Group 1: 0.40 g; p=0.038). Growth inhibition is significantly more evident when the drugs dosages are increased (Group 5: 0.17 g Vs Group 1: 0.40 g; p=0.024). Conclusions: The simultaneous administration of Bicalutamide and Raloxifene appears to have a synergistic effect on tumor growth inhibition in PC3 xenografts. The pathway(s) responsible for this observation may be independent of the androgen receptor as PC3 cells are AR negative and still affected by the combination over the drugs administered alone. Research is warranted to identify these potential pathways.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

Objectives: Evaluate the effects of "XGTQ" in the treatment of cirrhosis induced by Carbon tetrachloride (CCL4) in combination with alcohol and high-fat diet on Wistar rats. Materials and methods: Cirrhosis on white rats was induced by subcutaneously injecting CC14 at an initial dose of 5,0ml/kg, followed by 1,2ml/kg once a week in 10 weeks. Then, fed with synthetic food, added 20% fat, and 0.05% cholesterol and iron oxalate. Rats were administered every day with plain water and 1 day with water mixed with 30% ethanol. The rats were randomly divided into 5 groups and given distilled water (group 1 and 2 or control group), silymarin (group 3 or reference group) or the "XGTQ" drug extract (group 4, 5) for 4 weeks. Collected blood for biochemical test and liver were dissected to evaluate weight, morphology and quantified 4-hydroxyproline to evaluate fibrosis and collagen accumulation. Results: In cirrhotic wistar rats, "XGTQ" drug at 19.6 g/kg/24h and 58.8 g/kg/24h showed the ability of reducing the activity of enzymes AST, ALT in the blood (p<0.01), increasing plasma albumin and decreasing prothrobin time (p<.05); improving physical condition, macroscopic and microscopic images of H&E-stained liver; decreasing the concentration of hydroxyproline in the liver and reducing the level of cirrhosis on the masson-stained templates. The effects of "XGTQ" increased with the dose, and was equivalent to silymarin at the dose of 70 mg/kg/24h. Conclusion: The extract of "XGTQ" drug is effective in treating cirrhosis in Wistar rats.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

Haematological Indices

Solanum gilo (eggplant) is an edible vegetable whose leaf is reported to possess numerous medicinal properties due to its rich constituents. Against this backdrop, there is possibility that its consumption may have effect on haematological indices. Therefore this research sought to assess the effect of Solanum gilo leaf diet on some haemotological indices of albino wistar rats. About twenty four (24) albino wistar rats weighing between 120-150mg were randomly assigned into four groups of six animals each. Each rat was allowed to drinking water ad labitum. Control group received normal rodent chow while group 2 was fed 5% Solanum gilo diet. Group 3 was fed 10% Solanum gilo diet and group 4 received 20% Solanum gilo diet. The different diets were prepared by mixing different proportions of ground S. gilo leaves with rodent chow. Automated blood cell analyzer (Model PCE 210, Japan) was used for analysis of haematological parameters. Preliminary study on its proximate composition, showed the appreciable presence of crude fat, protein, fibre and carbohydrate. Consumption of S. gilo caused significant improvement in some blood parameters; notably packed cell volume (PCV), white blood cell (WBC) and platelet counts. Hence, eggplant is a nutritious vegetable with healing, the therapeutic and immunity properties. If exploited in human diet has the potentials of improving quality of life.

SummaryObjective: To investigate the effects of various activation methods on freeze–thawed rabbit oocytes developmental potential. Methods: Rabbit oocytes were vitrified by cryoleafs and cryoprotected with ethylene glycol and propanediol. After thawing, the oocytes were fertilized by intracytoplasmic sperm injection (ICSI). Surviving oocytes after ICSI were divided into five groups at random. Group 1: Oocytes (n = 30) activated 1 h after ICSI by calcium ionomycin (I0634); Group 2: Oocytes (n = 26) activated by strontium chloride an hour after ICSI; Group 3: Oocytes (n = 33) activated by I0634 twice; Group 4: Oocytes (n = 28) were activated by strontium chloride twice; Control Group: Inactivated oocytes (n = 39). Blastocysts derived from each group were transplanted to recipient rabbits. Results: Rates of fertilization, cleavage and blastocyst formation of Group 3 were higher than those of Group 1 and Group 2 (81.8% vs 33.3% vs 53.8%, 54.5% vs 16.7% vs 26.9%, p < 0.05; 15.2% vs 3.3% vs 7.7%, p > 0.05). The rabbit transplanted with embryos derived from Group 3 became pregnant. Embryos derived from double activation could implant into endometrium. Conclusion: Double activation may increase freeze–thawed oocytes developmental potential. After activation, oocytes cleavage velocity may be faster than that of oocytes without activation.

Ototoxicity is the general name of cochlear and vestibular organ injury resulting from encountering various therapeutic agents and chemical substances. Cisplatin is commonly used in the treatment of many cancers. In this study, the efficacy of intratympanic steroids was compared for preventing cisplatin ototoxicity. In this study, 32 (64 ears) rats were used by separating into 4 groups. Cisplatin was administered intraperitoneally to the first group (n = 8). Methylprednisolone and then cisplatin were administered intratympanically to the second group (n = 8). On the third group (n = 8), dexamethasone and then cisplatin were administered intratympanically. To the fourth group (n = 8), 0.9% NaCl and then cisplatin were given intratympanically. Otoacoustic emission (OAE) measurements and auditory brainstem responses (ABRs) tests were performed on all groups before and 72 hours after the procedure. Pretreatment of ABR-IV values were 4.29 ± 0.19 milliseconds in group 2 and 4.27 ± 0.16 milliseconds in group 3, whereas posttreatment ABR-IV values were 4.95 ± 0.35 milliseconds in group 2 and 4.65 ± 0.26 milliseconds in group 3. The ABR-IV values were measured significantly shorter in the rats given dexamethasone and methylprednisolone, according to control and cisplatin groups ( P < .001). Pretreatment of ABR I-IV interval values were 2.98 ± 0.34 milliseconds and 3.03 ± 0.42 milliseconds in group 1 and group 4, respectively, and ABR I-IV interval values in group 1 and group 4 posttreatment were 3.49 ± 0.39 milliseconds and 3.5 ± 0.39 milliseconds in group 1 and group 4, respectively. Auditory brainstem responses I-IV interval was significantly longer in the cisplatin and control group than in the rats given dexamethasone and methylprednisolone ( P < .001). After cisplatin treatment, OAE amplitudes decreased significantly in group 1 and group 4 for all frequencies, while OAE values were protected in methylprednisolone and dexamethasone group ( P < .001). In conclusion, it has been shown that both agents have protective effects on cisplatin ototoxicity, with dexamethasone slightly more than methylprednisolone.
