Nephroprotective Effect

The efficacy of a crude hydro-alcoholic extract of Cassia fistula (golden shower tree) fruit to protect the kidney against bromobenzene-induced toxicity was studied. Negative control mice received normal saline; positive control mice were given 460 mg/kg of bromobenzene; Cassia fistula treated mice received 200, 400, 600 and 800 mg/kg of Cassia fistula fruit extract followed by 460 mg/kg bromobenzene (daily by oral gavage for 10 days). On the 11th day, the mice were sacrificed, blood samples were obtained to assess blood urea nitrogen (BUN) and creatinine levels, and kidneys were removed for histological examination. We found that bromobenzene induced significant nephrotoxicity reflected by an increase in levels of BUN and creatinine that was dose dependently prevented by the Cassia fistula fruit extract. The nephroprotective effect of the Cassia fistula fruit extract was confirmed by the histological examination of the kidneys. To the best of our knowledge, this is the first study to demonstrate the protective effect of Cassia fistula in nephrotoxicity.

In the present study, hepatoprotective effect of Cassia fistula fruit extract was investigated in mice. Animals were divided into six groups receiving normal saline (1), bromobenzene (460 mg/kg) alone (2) and together with increasing doses (200, 400, 600, 800 mg/kg) of a crude hydro-alcoholic extract of Cassia fistula fruit (3-6, respectively). All administrations were carried out orally, daily, for 10 days. On the 11th day, animals were sacrificed. Serum activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and gamma glutamyl transpeptidase (γGT) were determined; serum levels of direct and total bilirubin were measured; furthermore, livers were prepared for histological examination. Our results showed that bromobenzene treatment alone elicited a significant increase in activities of AST, ALT, ALP (but not γGT), and it significantly elevated the levels of direct and total bilirubin. Co-treatment with Cassia fistula fruit extract, however, significantly and dose-dependently decreased the above-mentioned enzyme activities (with exception of γGT) and bilirubin levels, producing a recovery to the naive state. The protective effect of Cassia fistula fruit extract against liver injury evoked by bromobenzene was confirmed by histological examination as well. In conclusion, the Cassia fistula fruit extract has significant hepatoprotective effect in our murine model.

This research was conducted to study the protective effect of bee honey on the 7,12-dimethylbenz(a)anthracene (DMBA)- induced breast cancer in rat model. The study consisted of three groups: honey group, positive control group (PC), and negative control group (NC) to which the carcinogen was not administered. All rats were fed the diet recommended by the American Institute of Nutrition for growing rats (AIN-93G), with addition of honey (50 g/kg diet) to the honey group. All Rats were fed their diets ad libitum on 12 hours dark/light cycle. At the age of 50 days all rats in the honey and PC groups were gavaged once by the carcinogen DMBA with a dose of 80 mg/kg body Wt. After three weeks of carcinogen administration, rats were palpated weekly to detect any tumor growth. After 18 weeks, all rats were sacrificed. The palpable structures and the mammary glands along with associated lymph nodes were removed and fixed in saline formalin and prepared for histopathological examination. The results revealed that the honey group diet significantly (p < 0.05) reduced the incidence rate of mammary cancer, palpable tumor multiplicity, tumor size and weight compared to the PC group. In conclusion, multi floral honey has a protective effect against DMBA- induced mammary cancer in the initiation, promotion, and progression stages of DMBA-induced mammary carcinogenesis. However, further research is needed to reveal the mechanisms that might have contributed to the preventive effect of honey against mammary cancer.

This study evaluated the effect of titanium tetrafluoride (TiF4) varnish on the development of dentin carious lesions. Bovine root dentin samples were treated for 6 h with: (A) 4% TiF4 varnish (2.45% F); (B) 5.42% sodium fluoride (NaF) varnish (2.45% F); (C) 2% chlorhexidine (CHX) gel – positive control; (D) placebo varnish; or (E) untreated – negative control (n = 4 × biological triplicate, n = 12). Treated dentin samples were exposed to human saliva mixed with McBain saliva (1:50) for the first 8 h in 24-well plates. Thereafter, the medium was removed, and McBain saliva containing 0.2% sucrose was applied for 16 h. From days 2 to 5, McBain saliva with sucrose was replaced daily (37°C, 5% CO2). The demineralization was measured using transverse microradiography, while the effect on biofilm was analyzed using viability, extracellular polysaccharide (EPS), and lactic acid production assays. The data were statistically analyzed (p < 0.05). All treatments (fluorides and CHX) significantly reduced the biofilm viability compared to placebo varnish and negative control. However, none of them was able to reduce the colony-forming unit counting for total microorganism, total streptococci, and Streptococcus mutans. NaF significantly reduced the number of Lactobacillus sp. compared to negative control. No effect was seen on lactic acid production neither on EPS synthesis, except that CHX significantly reduced the amount of insoluble EPS. Both fluorides were able to reduce dentin demineralization compared to placebo varnish and negative control; TiF4 had a better effect in reducing mineral loss and lesion depth than NaF. Therefore, TiF4 varnish has the best protective effect on dentin carious lesion formation using this model.

Abstract This study aimed to evaluate the antimicrobial activity of a dentifrice containing an alcoholic extract of rosemary on oral bacteria, compared to a commercially available herbal dentifrice. Standard strains of Streptococcus mutans (ATCC 25175), Streptococcus oralis (ATCC 9811) and Lactobacillus rhamnosus (ATCC 7469) were used, as well as different toothpastes based on rosemary (TR), on propolis (TH), triclosan (positive control) (TPC) and non-fluoridated dentifrice (negative control) (TNC). Bacteria were seeded in Petri dishes and paper discs soaked with dilutions of dentifrice placed on the plates. The inhibition halos were analyzed. It was observed that TR did not show statistical difference in relation to the TH to inhibit S. mutans and S. oralis, while TH was more active against L. rhamnosus. The toothpaste containing rosemary extract had the ability to inhibit the growth of S. mutans, S. oralis and L. rhamnosus, revealing an antimicrobial activity similar to commercially available toothpastes for inhibition of S. mutans and S. oralis.

Introduction: Mahkota dewa (Phaleria macrocarpa) is an Indonesian fruit that contains antibacterial compounds, such as flavonoids, saponins, and tannins; it has been used as an alternative treatment for controlling infection. Objectives: This study aimed to examine the effect of mahkota dewa fruit extract on the formation of Porphyromonas gingivalis (P. gingivalis), Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), and Treponema denticola (T. denticola) biofilms in vitro. Methods: God’s crown fruit was extracted using the maceration technique, and then diluted into different concentrations (25%, 12.5%, 6.25%, 3.125%, and 1.56%) using phosphate buffered saline (PBS). P. gingivalis ATCC-33277, A. actinomycetemcomitans ATCC-29522, or T. denticola ATCC-35405 were cultured in brain heart infusion (BHI) broth, 24h (anaerobic-condition), and then each type of bacteria (108CFU/mL) was distributed into a 96-well microplate to form a biofilm. Subsequently, the fruit extracts were distributed into the biofilm-containing well plates and incubated for 1h, 6h, and 24h. A biofilm without the fruit extract and chlorhexidine-gluconate (0.2%) was used as the negative and positive control, respectively. Crystal violet (0.5%w/v) was used to determine the density of the remaining biofilm using a microplate spectrophotometer (600 nm). Data were statistically analyzed using one-way ANOVA, and p <0.05 was set as the level of significance. Results: The mahkota dewa fruit extracts significantly inhibited the formation of a biofilm for all three bacterial strains at all concentrations and for each incubation time (p <0.05) based on optical density (OD)±SD.  The best concentration of fruit extract to inhibit biofilm formation was 25% for P. gingivalis (OD=0.19±0.06), 12.5% for A. actinomycetemcomitans (OD=0.14 ± 0.16), and 25% for T. denticola (OD=1.17±0.19) in comparison to the biofilm mass of the negative control, which was 1.67±0.06, 1.17±0.34, 2.66±0.38 for P. gingivalis, A. actinomycetemcomitans, and T. denticola, respectively. Conclusion: Based on these results, mahkota dewa fruit extract can inhibit the formation of biofilm on P. gingivalis, A. actinomycetemcomitans, and T. denticola, and it may potentially be used to prevent the infection associated with periodontal disease.

Boar Spermatozoa

Butylated hydroxytoluene (BHT) has proven to be efficient as a supplement for cryopreservation boar spermatozoa (Roca et al. 2004 J. Androl. 25, 397–405). Moreover, it has been successfully used as an egg yolk substitute to cryopreserve goat spermatozoa (Khalifa and El-Saidy 2006 Anim. Reprod. Sci. 93, 303–315). The objective of this study was to evaluate the effectiveness of BHT as an egg yolk substitute for freezing boar spermatozoa. Nine sperm-rich ejaculate fractions were collected from 3 boars (3 ejaculates per boar) using the gloved-hand method. After centrifugation (2400g for 3 min), the sperm pellet of each ejaculate was split into 5 aliquots. The aliquots were diluted (to a final concentration of 1 � 109 sperm/mL) in a Tris-citric-glucose extender with 3% glycerol and supplemented with 20% egg yolk (positive control, PC aliquot) or BHT at the final concentrations of 0 (negative control, NC aliquot), 0.2, 0.4, and 0.8 mM. Diluted semen samples were dispensed into 0.5-mL straws, and frozen in a programmable cell freezer at 20�C min. Thawing was carried out in a water bath at 70�C for 8 s. Post-thaw sperm survival was assessed according to total sperm motility (TSM, %) using a CASA system (SCA�; Microptic, Barcelona, Spain), and plasma membrane integrity (PMI, %) and acrosome membrane integrity (AMI, %) using a flow cytometric procedure (SYBR-14/propidioum iodide/FITC-phycoerythrin), at 30 and 150 min post-thawing in diluted Beltsville thawing solution with spermatozoa held in a waterbath at 37�C (3 straws per ejaculate). Data were analyzed using a ANOVA mixed model including the main effects of aliquot, boar, post-thaw assessment time, and their interactions, with ejaculate and straw as random effects. All main effects had significant influence (P ≤ 0.01) in all post-thaw sperm assessments. However, no interactions (P ≥ 0.05) among main effects were shown. Data were combined for the 2 post-thaw assessment times. The best (P ≤ 0.05) post-thaw sperm quality (mean � SEM) was achieved in PC aliquots (47.11 � 3.10, 58.98 � 2.78, and 51.35 � 3.42 for TSM, PMI, and AMI, respectively). In NC aliquots, the percentage of TSM, PMI, and AMI were always below 1% (P ≤ 0.05). BHT has a beneficial (P ≤ 0.05) effect on post-thaw sperm assessments, and no differences (P ≥ 0.05) among concentrations were shown. The mean post-thaw sperm quality in the BHT aliquots was 8.50 � 0.80, 20.29 � 0.53, and 16.03 � 0.55 for TSM, PMI, and AMI, respectively. On the basis of these data, we can conclude that BHT has a protective effect for boar spermatozoa during the cryopreservation process. However, BHT alone is insufficient to replace the protective effect of egg yolk. This work was supported by CICYT (AGF2005-00706), Madrid, Spain.

Hypnotic Activity

Background: Sleep disorders are among the most common psychiatric and medical conditions. Objective: The present study aimed at investigating the hypnotic activity of the hydro-alcoholic extract of Capparis spinosa (HAE) in mice. Method: Three doses of HAE (30, 60 and 120 mg/kg) and three fractions of it, namely n-hexane fraction (NHF), water fraction (WF), and ethyl acetate fraction (EAF), were given in comparison with diazepam (3mg/kg body weight i.p.) as positive control and saline as negative control. After 30 min, pentobarbital (30 mg/kg body weight i.p.) was administrated. In addition, LD50 of HAE was examined and the cytotoxicity of HAE was assessed in l929 cells using the MTT assay. Moreover, for motor-coordination ability 30 mins after administration of HAE rota-rod test was performed. Results: The results exhibited that the HAE and all the fractions significantly augmented pentobarbital induced sleeping time which was comparable to that of induced by diazepam. The LD50 value was 2.4 g/kg. The extract did not induce any cytotoxic effects in L929 fibroblast cells. HAE did not affect the animals’ performance on the rota-rod test. Conclusion: Our finding suggests that hydro-alcoholic extract of C. spinosa possesses hypnotic potential that may require further scientific investigations.
