Introduction: Epilepsy is a group of chronic neurological disorders characterized by seizures. The aim of the present study was to investigate the effects of pretreatment with Satureja bachtiarica essential oil in preventing epilepsy. Methods: In this experimental study, 50 mice were randomly assigned to five groups of 10 each. The control group received normal saline plus tween80 and, 30 min later, PTZ. Groups 2 and 3 were treated with S. bachtiarica essential oil at 50 and 100 mg/kg and 30 min later received PTZ, respectively. Group 4 received diazepam and 30 min later received PTZ. Group 5 received flumazenil and 30 min later received PTZ. After the last injection of PTZ, the time of seizure onset, seizure severity and score, the completion time of each seizure (attack episode), and mortality rate in different groups were recorded and compared. Results: The administration of S. bachtiarica essential oil at 50 and 100 mg/kg to PTZ-treated mice caused significant increase in latency to first seizure and survival, and significant decrease in the frequency of the head and upper limbs seizure, total body seizures, tonic seizures, and jumping. S. bachtiarica essential oil at 100 mg/kg caused a significant decrease in the head ticks frequency. The administration of flumazenil significantly inhibited S. bachtiarica essential oil induced effects and increased the head and upper limbs seizures, tonic seizures, and jumping. Conclusion: The present study demonstrated that S. bachtiarica essential oil can prevent PTZ-induced seizure and these findings authenticate the traditional claims about use of Satureja bachtiarica in treatment of epilepsy.

Background: Coenzyme Q10 is a well-known cofactor in the mitochondrial electron transport chain required for ATP production. Coenzyme Q10 is recognized as an intracellular antioxidant that protects cell membrane phospholipids, mitochondrial membrane protein, and plasma low-density lipoprotein against oxidative damage caused by free radicals. Diabetes and its complications have been related to increased levels of free radicals and systemic proinflammatory cytokines and to an abnormal lipid profile. The aim of this study was to investigate the effects of coenzyme Q10 supplementation on some cytokine levels in streptozotocin-induced diabetic rats.Materials, Methods & Results: In this study, 38 healthy, adult male rats were used. The rats were divided into 5 groups. All animals were housed in separated cages during the four weeks. The animals in group 1 was fed standard rat pellets for 4 weeks. It was administered at 0.3 mL corn oil intraperitoneally daily for four weeks in group 2 animals. The animals in group 3 was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. Group 4 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and group 5 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and then was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. During the experiment, three animals from group 4 and one animals from group 5 were died due to streptozotocin-induced hypoglycemia. At the end of the study, blood samples were taken from all animals. In these blood samples, IL-4, IL-6, IL-10 and TNF-α plasma levels were determined with ELISA using sandwich enzyme-linked immunosorbent method via commercial kits. In this study, IL-4 level as an anti-inflammatory cytokine significantly decreased (P < 0.05) with diabetes induction compared to control group level. IL-10 level in diabetic group was statistically different (P < 0.05) from control group level. CoQ10 application to diabetic animals improved the falling in IL-10 level of diabetic group (P < 0.05). IL-6 and TNF-α levels in diabetic group significantly increased (P < 0.05) in parallel with each other compared to control group levels. The same parameters were reduced (P < 0.05) by CoQ10 application in diabetic animals.Discussion: In this study, the occurred changes in pro- and anti-inflammatory cytokines with experimentally induced diabetes are expected results and these results are consistent with some studies related diabetes. These results may be considered to hazardous effects and inflammation caused by diabetes on liver, pancreas and other tissues. CoQ10 suppressed the increments in plasma pro-inflammatory cytokine levels, whereas it restored the reducing in anti-inflammatory cytokine levels arising due to diabetes. The obtained results from this study after CoQ10 application supported similar studies used CoQ10 application against deleterious effects of diabetes in animals and humans. Therefore, it is possible to say that CoQ10 may play important role in regulation of imbalance between inflammation markers in diabetes conditions and further studies are needed to clear the beneficial effects of CoQ10 treatment on the other inflammation markers in diabetes status.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

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.

The aim of the present study was to evaluate the efficacy of interfacial bonding between resin cement and titanium alloy conditioned with different Photobiomodulataion Therapy (PBT) in comparison with conventional regimes. Seventy-five samples of titanium bar were segmented polished; and based on conditioning regime divided into five groups (15 each specimens). Group 1: No treatment (control), Group 2: Sand blasting with 120 µm Al2O3, Group 3: Er,Cr:YSGG (ECL), Group 4: Er:YAG laser (EYL), Group 5: Nd:YAG laser (NYL). After different conditioning regimes, resin cement was mixed and applied. All specimens were thermocycled for 500 cycles and positioned on universal testing machine for shear bond strength testing. Modes of failure was assessed by a single examiner using stereomicroscope at 40× magnification. Three pairs of specimens in each group were sputter coated and scanning electron microscope (SEM) images were taken at 1000× magnification using 20 Kv. The highest SBS values were observed in group 2 (14.25±2.29 MPa) and the lowest bond values were displayed in group 1 (6.98 ±0.59 MPa). Titanium alloy abutments conditioned with different laser prototypes ECL (11.22±1.40 MPa), EYL (9.29±1.22 MPa) and NYL (9.12 ±1.84 MPa) exhibited comparable SBS (p > 0.05). Adhesive failures were primarily dominant among all experimental groups. Photo-biomodulation in the form of ECL lasers has the potential to be used as a supplement to sandblasting procedure in conditioning of cement retained titanium alloy implant abutments.

The reproductive performance of sows is influenced by numerous factors, including environment. The time of ovulation in response to hormonal treatment might vary depending on climate. Because control of ovulation in pigs using hormonal treatments has not been studied in the tropical climate, the effect of hCG or GnRH analog (buserelin) on the time of ovulation in weaned sows was investigated. Thirty-three multiparous Landrace (L; n = 14) and Yorkshire (Y; n = 19) sows housed in the mating and gestation unit on a commercial swine farm in Thailand were used. The average of maximum and minimum daily temperature and daily humidity during experiment was 35°C and 25°C and 31%, respectively. Estrus detection by back pressure test and presence of a mature boar was performed every 6 h. Only sows with weaning to estrus interval (WOI) of ≤7 days were studied. Estrous sows were randomly allocated to 3 groups: a control group (4 Y and 6 L), which was given no treatment; a group (5 Y and 5 L) given 750 IU of hCG i.m. at the beginning of estrus (hCG group); and a group (5 Y and 8 L) given 10 μg of GnRH analog i.m. at the beginning of estrus (GnRH group). The mean time of ovulation was monitored by transrectal ultrasonography every 6 h from the onset of estrus. Interval from onset of estrus to mean time of ovulation (EOI) was analyzed using general linear model procedures of SAS (version 9.0; SAS Institute, Cary, NC, USA). Least squares means and standard deviations of EOI were compared using ANOVA. The proportion of sows ovulating within 45 h after onset of estrus was compared using Fisher’s exact test. Differences with P < 0.05 were considered significant. All of the sows in the control and hCG groups ovulated within 5 days after onset of estrus, but 3 out of 13 (23%) sows in the GnRH group developed cystic follicles; these 3 sows were excluded from the analyses. Overall, WOI was 3.8 ± 0.9 days and did not differ among the groups (P ± 0.05). The breed of sow had no effect on the EOI (P ± 0.05). Although the EOI did not differ among the control (43.0 ± 19.2 h), hCG (40.2 ± 5.5 h), and GnRH (37.5 ± 10.3 h) groups (P ± 0.05), variation was less (P = 0.001) after administration of hCG or GnRH. In addition, the proportions of sows that ovulated within 45 h after onset of estrus in the hCG (9/10 sows) and GnRH (8/10 sows) groups tended to be higher than in the control group (5/10 sows; P = 0.10). In conclusion, results indicate that both hCG and GnRH are efficacious in inducing ovulation at a predictable time in weaned, spontaneously estrous sows. The occurrence of follicular cysts in GnRH-treated sows requires further investigation.

Background: Diabetes mellitus is a multifactorial metabolic disorder with several microvascular and macrovascular complications. Several plants have been used as dietary adjuvants to conventional drug therapy. Garcinia indica exhibits significant hypolipidemic and hypoglycemic activity. This study was conducted to evaluate the hypoglycemic effects of methanolic extract of seeds of Garcinia indica on blood glucose levels in Streptozotocin induced diabetic albino rats.Methods: Five groups of wistar albino rats (n=6) weighing 150-200g of either sex aged 3-4 months were obtained for the study. After overnight fasting, streptozotocin (50mg/kg) was administered intraperitoneally to induce diabetes. Five groups are: Group-1: Non diabetic control group, Group-2: diabetic control, Group-3: diabetic standard, Group-4: test group, Group-5: half of test + half of standard. Fasting blood sugar was estimated on 1, 3, 7, 14 and 28th day by capillary blood glucose method. The data obtained were subjected to statistical analysis.Results: In this study, following Streptozotocin administration the blood glucose levels increased in all groups on day 0. In group 2, blood glucose level gradually increased to 445.6±1.75mg/dl over a period of 4 weeks. Following glibenclamide administration in Group 3 - there was a gradual reduction in blood glucose levels: 269.8mg/dl - day 7 to 101.8mg/dl - week 4. Group 4 - persistent and significant (p<0.05) fall in blood glucose levels reaching upto 107mg/dl at the end of 4 weeks. Group 5 - 330mg/dl on day 1 which significantly (p<0.05) reduced to 101mg/dl on day 28. There was improvement in weight in group 4 and group 5 diabetic rats.Conclusions: The extract alone and in combination with glibenclamide showed significant hypoglycemic activity in comparison to diabetic control group.

AIM: The aim of the present study was to evaluate the effect of various intermediate irrigating solutions in the removal of orange-brown precipitate formed due to alternative use of sodium hypochlorite (NaOCl) and chlorhexidine (CHX) root canal irrigants. METHODS: The root canals of 50 mandibular premolars were prepared using ProTaper Universal Rotary instruments (Dentsply Maillefer, Ballaigues, Switzerland) up to size F3. The roots were randomly divided into five experimental groups specified by the intermediate irrigant used; Group 1: No intermediate irrigant used (control), Group 2: Saline, Group 3: 7% maleic acid (MA), Group 4: 4% sodium thiosulfate, and Group 5: 70% isopropyl alcohol (n = 10). After final irrigation with CHX, the specimens were evaluated for the presence/absence of orange-brown precipitate under stereomicroscope. RESULTS: Mean precipitate for all experimental groups was calculated using ANOVA F test which showed orange-brown precipitate (parachloroanaline) in all groups except Group 4 and Group 5 which were highly significant (p < 0.001) at all the levels of root canal. Intergroup pairwise comparison was done using Tukey’s post hoc test. CONCLUSION: About 7% MA is effective in minimizing the formation of orange-brown precipitate when used as intermediate irrigant between NaOCl and CHX. However, the precipitate was not observed with 4% sodium thiosulfate and 70% isopropyl alcohol.

The main purpose of this study was to explore the effects of Spirulina (Spirulina platensis) as a feed supplement by replacing Vitamin-Mineral Premix on the performance of broiler. The study explored that final body weight was 1039, 1070, 1044, 1065, 1117 and 893 g/bird in group 1, 2, 3, 4, 5 and 6 where significantly (p<0.5) higher weight observed in Spirulina group (5) but lower in negative control group (6). Feed intake observed more or less similar in all groups (1483±24g; p>0.5). Feed conversion ratio (kg FI/kg LWG) observed significantly different like 1.72, 1.65, 1.69, 1.62, 1.61 and 1.99 in group 1, 2, 3, 4, 5 and 6 respectively (p<0.5) where higher in negative group (6) and control group (1), but is lowest and similar in 75% Spirulina group (4) and highest (100%) Spirulina group (5). %Ash of different dietary groups were 46.35, 46.54, 48.93, 49.93, 55.07 and 46.92 of group 1, 2, 3, 4, 5 and 6 respectively. The %ash of bone was gradually increased among dietary groups and the best result was obtained in 100% Spirulina group 5 (55.07). It also revealed that diets containing no vitamin-mineral premix with 100% Spirulina improve the performance of broiler. The findings suggest that poultry farmer can use spirulina as a feed item for broiler for more yield.
