Abstract
BACKGROUND The placement of ligatures in the cervical area of rat molars is considered as a predictable model to induce periodontitis. OBJECTIVES The present explorative study aimed to compare the efficacy of metal wires (MWs), without or with sandblasting, versus silk ligatures (SLs) in inducing periodontal bone loss in rats. MATERIALS AND METHODS Twenty-four Wistar rats were randomly divided into three groups of eight rats that received three different types of ligatures (MW, sandblasted wire [SMW], and SL) around their first right mandibular molar, while the contralateral tooth was left without the ligature and served as a control. Bone loss was assessed by measuring the distance from the cementoenamel junction (CEJ) to the bone crest at the distal aspect of the first molar on central mesiodistal sections generated from micro-CT scans taken 24 and 35 days after ligature placement. RESULTS In the SL group, only in two rats the ligatures were retained until the end of the 24-day period; in all other animals, the ligatures were lost at some time point. In the SMW, the ligatures were retained only for the 24-day period. In the MW group, no ligatures were lost. Irrespective of the group or experimental period, the difference in the crestal bone level between ligated and control teeth was in most cases z < 0.20 mm, that is, in 19 out of 25 pairs of teeth. In a few cases, the bone crest was more apically located at the control teeth compared to the ligated ones (four cases each, during both 24- and 35-day experimental periods). CONCLUSIONS Bone loss was minimal during the experimental period, with no significant differences between the test and control teeth, or among the three types of ligatures. MWs, not even roughened, do not seem to be a better alternative to SLs for inducing bone loss in the experimental periodontitis model in the rat. This assumption, however, has to be confirmed in a larger, well-powered study.

Abstract
Chronic oral diseases are boring, long-term, and discomfort intense diseases, which endanger the physical and mental health of patients constantly. Traditional therapeutic methods based on medicines (including swallowing drugs, applying ointment, or injection in situ) bring much inconvenience and discomfort. A new method possessing accurate, long-term, stable, convenient, and comfortable features is in great need. In this study, we demonstrated a development of one spontaneous administration for the prevention and therapy on a series of oral diseases. By uniting dental resin and medicine-loaded mesoporous molecular sieve, nanoporous medical composite resin (NMCR) was synthesized by a simple physical mixing and light curing method. Physicochemical investigations of XRD, SEM, TEM, UV-vis, N2 adsorption, and biochemical experiments of antibacterial and pharmacodynamic evaluation on periodontitis treatment of SD rats were carried on to characterize an NMCR spontaneous medicine delivery system. Compared to existing pharmacotherapy and in situ treatments, NMCR can keep a quite long time of stable in situ medicine release during the whole therapeutic period. Taking the periodontitis treatment as an instance, the probing pocket depth value in a half-treatment time of 0.69 from NMCR@MINO was much lower than that of 1.34 from the present commercial Periocline ointment, showing an over two times effect.

Abstract
Background: Periodontitis is a prevalent disease caused teeth lost. The present rat models inducing periodontitis with thread ligature and metal steel ligature have some disadvantages. Methods: We modified the existing rat ligature periodontitis model by fixing the thread ligature on the metal steel ligature passed through the gap between the first and second molars of rats with detailed modeling steps and illustrations. We research the pathological process of the periodontitis induced by the modified model, and briefly compared the modified model with the thread ligature model and the metal steel ligature model. Result: Our experimental results showed that there was an aggravation in inflammatory infiltration and alveolar bone resorption in modeling area within 14 days of initial induction. After that, the inflammatory infiltration was reduced. And no significant increase in alveolar bone destruction appeared. The modified model was more reliable compared to the thread ligature model, and had greater ability of bacterial aggregation compared to the metal steel ligature model. Conclusion: The modified method covered pathological process of the periodontitis, and showed sufficient efficiency and reliability in inducing rat periodontitis.

Comparative Testing of Two Ligature-Induced Periodontitis Models in Rats: A Clinical, Histological and Biochemical Study. BIOLOGY 2022; 11:biology11050634.

Abstract
Simple Summary This study is the first study comparing the same parameters of inflammation in two periodontal disease experimental models proposed by the literature and used in the research. The importance of the method used to induce periodontitis in animals resides in the efficacy of proposed technologies and treatments used in preclinical trials. The inflammatory markers Interleukin-1 alpha(IL-1α), Tumor Necrosis Factor-alpha (TNF-α), and high sensitive C reactive protein (hsCRP), the hematological analyses, and the histological probes showed a similar and reproducible periodontal inflammation for the molar induced periodontitis model. Ligation-induced periodontitis in rats has limitations and will never reproduce all aspects of periodontal disease in humans. The findings of this study with the complex association between clinical, biochemical, and histological aspects of the two experimental models of periodontal pathology induction in rats suggest that a similar periodontal pathology to the one we find in humans is best replicated in rats with the molar induced periodontitis model. Abstract Experimental animal models for studying the mechanisms of periodontitis and its links are a better alternative to in vitro studies. The aim of this study is to compare two ligature induced periodontitis models and validate the best one for further use in research. An experimental study was performed on male Wistar rats that were divided into three groups: Test 1 (n = 10), incisor ligated, Test 2 (n = 10), molar ligated, and Control (n = 10). The animals were clinically evaluated at the beginning and at the end of the experiment by recording body weight, gingival bleeding index, tooth mobility score, changes in color, and consistency of gingival tissue. Two blood samples were obtained for each animal at baseline and at the end of the experiment. The hematological parameters Interleukin-1 alpha (IL-1 α), high sensitive C Reactive Protein (hsCRP), and Tumor Necrosis Factor-alpha (TNF-α) were measured. Seven days after the induction of periodontitis, the animals were sacrificed, and samples were prepared for histological evaluation. The results of this research demonstrated that the association between clinical, histological, and biochemical parameters initiate a periodontal pathology in the molar induced model in rats while the incisor experimental model initiates only a moderate and incomplete periodontal inflammation, mainly due to mechanical irritation.

Abstract
OBJECTIVES Periodontitis is closely associated with kidney disease and reactive oxygen species (ROS) involvement. Mitochondria are the primary source of both endogenous ROS and renal energy. We investigated whether resveratrol (RSV) prevents renal injury and mitochondrial dysfunction in periodontitis rats. METHODS Thirty male Wistar rats were divided into control, experimental periodontitis (Ep), and Ep-RSV groups. To induce periodontitis, a steel ligature was placed on the cervix of the bilateral first maxillary molars. RSV (50 mg/kg/d) to the Ep-RSV group and vehicle to the Ep and control groups were gavaged. After 8 weeks, alveolar bone loss, pocket depth, gingival blood index, and tooth mobility were assessed. Oxidative stress parameters, mitochondrial structure, mitochondrial membrane potential (MMP), mitochondrial ROS, adenosine triphosphate (ATP), sirtuin 1 (SIRT1), and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) were analysed in renal. Renal function and histology were also evaluated. RESULTS Compared with the control group, the Ep group showed renal structural destruction, elevated oxidative stress levels, mitochondrial structure destruction, MMP loss, mitochondrial ROS accumulation, ATP reduction, and decreased SIRT1 and PGC-1α levels. RSV prevented these destruction (p < .05). However, there was no significant impairment in renal function (p > .05). CONCLUSIONS Periodontitis induced mitochondrial dysfunction in renal tissues. Resveratrol exerts a preventive effect on periodontitis-induced kidney injury by preventing mitochondrial dysfunction.

Abstract
Dental plaque biofilms are believed to be one of the principal virulence factors in periodontitis resulting in tooth loss. Traditional mouthwashes are limited due to the continuous flow of saliva and poor drug penetration ability in the biofilm. Herein, we fabricated an antibiotic delivery platform based on natural polysaccharides (chitosan and cyclodextrin) as a novel mouthwash for the topical cavity delivery of minocycline. The penetration and residence mechanisms demonstrate that the platform can prolong the residence time up to 12 h on biofilms. Furthermore, sustained release can enhance the penetration of drugs into biofilms. In vitro antibiofilm experimental results indicated that the mouthwash effectively kills bacteria and eradicate biofilms. Effective treatment in vivo was confirmed by the significantly reduced dental plaque and alleviated inflammation observed in a rat periodontitis model. In summary, this novel platform can improve antibiofilm efficiency and prevent drugs from being washed away by saliva, which may provide benefits for many oral infectious diseases.

Abstract
OBJECTIVES The present study aimed to compare two different models of orthodontic tooth movement (OTM) in rats by evaluating tooth movement efficiency and periodontal tissues remodelling. DESIGN Fifteen animals were randomly distributed into 3 groups: control group (untreated); ligature appliance (LA) as experimental OTM using a closed coil spring fixed around maxillary first molar by steel ligature; occlusal appliance (OA) as experimental OTM using a closed coil spring attached on the occlusal surface of the maxillary first molar. After 15 days, all animals were euthanized, and the maxilla of each animal was collected for qPCR, micro-computed tomography, and histological analyses. RESULTS Interleukin-1 beta, interleukin-6, and tumor necrosis factor-alpha gene expressions were significantly upregulated in the animals of the LA group as compared to the other groups. No significant difference was observed in tooth displacement between both methods. The LA group presented higher linear bone loss and lower values of bone volume fraction, bone mineral density, trabecular number and increased values of trabecular separation compared to the other groups. The birefringent collagen content in the tension side of the periodontal ligament contained significantly lower collagen content in the LA group than in the control group. Furthermore, on the pressure side, the collagen content was significantly lower in the LA and OA groups than in the control group. CONCLUSIONS The OA group presented little or no deleterious effect on periodontal tissues compared to the LA group, suggesting its use may be more reliable for OTM induction in rats for 15 days.

Abstract
BACKGROUND Periodontitis is a chronic inflammatory and multifactorial disease that affects the periodontal structures and can cause alterations in the hepatic tissue. The aim of the present study was to evaluate whether a diet with food restriction can decrease oral and liver alterations associated with ligature-induced periodontitis. METHODS Twenty-four female Wistar rats were used in this study, randomized into three groups (n = 8 for each group): control (regular food); periodontitis (regular food + periodontitis induced with ligatures); and food restriction (diet with food restriction and periodontitis induction). The following periodontium parameters were analyzed tooth mobility (TM), probing pocket depth (PPD), gingival bleeding index (GBI), and alveolar bone height (ABH). In the liver, the levels of oxidative stress markers-malondialdehyde (MDA), glutathione (GSH), total cholesterol, and levels of myeloperoxidase (MPO) activity were measured. Liver samples were analyzed for histopathological score. In the blood tissue, the levels of enzymes alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose, total cholesterol, and the high-density lipoprotein (HDL) were also evaluated. RESULTS The animals that received a diet with food restriction + periodontitis showed a decrease in hepatic histopathological score (P < 0.05) when compared with the periodontitis group, the same for glucose, total cholesterol, ALT, AST, and ABH data. The group with food restriction + periodontitis showed a decrease in the histopathological liver score (P < 0.05) compared with the group with periodontitis. CONCLUSION This study revealed that food restriction reduced oral damages, as well as hepatic, blood and alveolar bone alterations associated with ligature-induced periodontitis in rats.

Abstract
BACKGROUND AND OBJECTIVE Periodontitis may crosstalk with renal diseases, yet that remains unclear. We investigated whether the renal alterations caused by induced periodontitis are reversible after removal of the ligatures in experimental ligature-induced periodontitis. MATERIAL AND METHODS Twenty-four female rats were divided into three groups: control (without periodontitis), periodontitis (20 days of ligature-induced periodontitis), and P20-20 (20 days of ligature-induced periodontitis and 20 days after ligature removal). The following periodontal parameters were assessed: gingival bleeding index, probing pocket depth, myeloperoxidase activity, and alveolar bone height. For renal tissues, histopathology, malonaldehyde (MDA) levels, glutathione (GSH) content, and renal weight were evaluated. In the blood, creatinine, uric acid, albumin, total cholesterol, total protein, and glucose levels were assessed. Total protein and creatinine levels in urine were also investigated. RESULTS Rat renal tissues did not demonstrate reversal of periodontitis-related changes in the P20-20 group in terms of MDA, GSH, and histopathological evaluations when compared to the periodontitis group. Accordingly, only total cholesterol levels were reversible in the P20-20. CONCLUSION Renal alterations caused by ligature-induced periodontitis persisted even after removal of ligatures in rats.

Abstract
BACKGROUND AND OBJECTIVE This study aimed to assess the effectiveness of the treatment with alpha-terpineol (αTPN) complexed with beta-cyclodextrin (βCD) on oral, blood, and hepatic parameters in ligature-induced periodontitis. MATERIAL AND METHODS Forty female rats were distributed among the following groups: control (vehicle solution), periodontitis (ligature + vehicle solution), 5 mg/kg of αTPN-βCD (ligature), and 25 mg/kg of αTPN-βCD (ligature). Compounds were administered daily via intraperitoneal injection over a 20-day period. Periodontitis was induced with the bilateral insertion of ligatures around the first lower molars of each rat. Oral parameters, as well as blood biomarkers, were measured: histopathological assessment of the hepatic tissue was carried out using light and transmission electron microscopy. RESULTS The treatment with αTPN-βCD significantly improved several oral parameters and blood biomarkers in comparison with rats with periodontitis. In addition, the treatment with αTPN-βCD significantly ameliorated the steatosis score and reduced the number of lipid droplets and the amount of foamy cytoplasm in the hepatocytes of rats with periodontitis. CONCLUSION The results obtained suggest that the treatment with αTPN-βCD improves several oral and blood parameters in rats with experimental periodontitis. In addition, hepatic alterations caused by periodontitis were ameliorated in the rats treated with αTPN-βCD.

Abstract
OBJECTIVES This study investigated the effect of Liraglutide (LIRA) on osteogenic differentiation of human periodontal ligament cells (hPDLCs) stimulated by Porphyromonas gingivalis lipopolysaccharide (Pg-LPS) and its mechanismin in vitro. Further, investigated the osteoprotective and anti-inflammatory effects of LIRA in periodontitis in vivo. MATERIALS AND METHODS ALP staining, Alizarin red staining(AR-S), qRT-PCR, Western Blot, and immunofluorescence staining were used to elucidate the effect of LIRA on osteogenesis of hPDLCs. Western Blot was performed to evaluate the Wnt/β-catenin signaling-related protein. Moreover, male Wistar rats model of periodontitis were established to assess the anti-inflammatory and osteoprotective effect of LIRA in vivo. RESULTS After LIRA treatment, the formation of mineralized nodules was increased, the expression of ALP and Runx2 were upregulated. Moreover, Pg-LPS strongly activated the Wnt/β-catenin signaling pathway and reduced the osteogenesis of hPDLCs. But these effects were reversed by LIRA. The in vivo results showed that treatment with LIRA resulted in reduced inflammatory cell infiltration in periodontal tissues and decreased concentrations of TNF-α, IL-1β, and IL-6, and it reduced alveolar bone resorption. CONCLUSIONS Systemic administration of LIRA solution is a potential treatment for reducing inflammation and bone loss in periodontal disease. This suggests that LIRA can be used as a potential drug for the treatment of periodontitis. CLINICAL SIGNIFICANCE We showed that systemic administration of LIRA can have a beneficial effect in periodontitis. It can be used as a potential drug for the treatment of periodontitis.

Abstract
Periodontitis is a common disease caused by plaque biofilms, which are important pathogenic factors of many diseases and may be eradicated by antibiotic therapy. However, low-dose antibiotic therapy is a complicated challenge for eradicating biofilms as hundreds (even thousands) of times higher concentrations of antibiotics are needed than killing planktonic bacteria. Polymer vesicles may solve these problems via effective antibiotic delivery into biofilms, but traditional single corona vesicles lack the multifunctionalities essential for biofilm eradication. In this paper, we aim to effectively treat biofilm-induced periodontitis using much lower concentrations of antibiotics than traditional antibiotic therapy by designing a multifunctional dual corona vesicle with intrinsic antibacterial and enhanced antibiotic delivery capabilities. This vesicle is co-assembled from two block copolymers, poly(ε-caprolactone)-block-poly(lysine-stat-phenylalanine) [PCL-b-P(Lys-stat-Phe)] and poly(ethylene oxide)-block-poly(ε-caprolactone) [PEO-b-PCL]. Both PEO and P(Lys-stat-Phe) coronas have their specific functions: PEO endows vesicles with protein repelling ability to penetrate extracellular polymeric substances in biofilms ("stealthy" coronas), whereas P(Lys-stat-Phe) provides vesicles with positive charges and broad spectrum intrinsic antibacterial activity. As a result, the dosage of antibiotics can be reduced by 50% when encapsulated in the dual corona vesicles to eradicate Escherichia coli or Staphylococcus aureus biofilms. Furthermore, effective in vivo treatment has been achieved from a rat periodontitis model, as confirmed by significantly reduced dental plaque, and alleviated inflammation. Overall, this "stealthy" and antibacterial dual corona vesicle demonstrates a fresh insight for improving the antibiofilm efficiency of antibiotics and combating the serious threat of biofilm-associated diseases.

Abstract
Gingivitis is a common and mild form of periodontal disease and can be described as a limited inflammation of the gingiva. This study aims to develop and characterize rapid releasing mucoadhesive fibers containing ornidazole with electrospinning process for the treatment of gingivitis. Polyvinylpyrrolidone (PVP) was chosen as a polymer and used at different concentrations of 10%, 12.5%, and 15%. Scanning electron microscopy images showed that fiber diameters increased with increasing polymer concentrations. Tensile strength and elongation at break values of fibers increased with increasing PVP amount, whereas the loading of ornidazole into the fibers decreased these parameters. The contact angle values of all fibers were found to be 0° due to the hydrophilic nature of PVP. Ornidazole was released within 5 min and diffused from all of the fibers faster than that of gel and solution formulations. Electrospun ornidazole fibers were found efficient against Porphyromonas gingivalis in antimicrobial activity studies. The results demonstrated that ornidazole loaded fibers could be a potential drug delivery system for the treatment of gingivitis.

Abstract
Porphyromonas gingivalis is a pathogenic Gram-negative anaerobic bacterium that colonizes the subgingival region of gums. These bacteria can invade periodontal tissues, form plaques, and produce volatile sulfur compounds (VSC) and volatile organic compounds (VOC). Egg yolk immunoglobulin (IgY) that was specifically produced in egg yolks after chickens were challenged with P. gingivalis could control and prevent oral diseases caused by P. gingivalis. The releases of P. gingivalis offensive metabolic odors in vitro and in vivo were determined using a Halimeter and GCMS. With IgY bacterial growth was inhibited, and the relative amounts of VOC and VSC were decreased. The scores for the oral health index and the levels of IL-6 and TNF-α are also decreased. All treatment groups showed significant anti-inflammatory effects, which strongly suggests that specifically IgY against P. gingivalis may be an effective treatment for the prevention and protection of periodontal inflammation and halitosis.

Abstract
BACKGROUND Periodontitis is a chronic inflammatory disease caused by Porphyromonas gingivalis that leads to a series of periodontal tissue injuries. Egg yolk immunoglobulins (IgY) is procuded in egg yolk and inhibits P. gingivalis. OBJECTIVE The aim was to evaluate the effect of IgY on experimental periodontitis caused by P. gingivalis. METHODS The second molars of rats were ligatured using medical 5-0 silk and smeared with P. gingivalis to induce experimental periodontitis. Then, the rats were smeared with 2 mL IgY solutions or 0.9% NaCl in the oral cavity for up to 4 wk. The scores for gingival index, plaque index and probe on bleeding, the levels of IL-6 and TNF-α, X-ray radiography and histology were used to determine the efficacy of the IgY on experimental periodontitis. RESULTS The clinical indices improved; the levels of IL-6 and TNF-α were significantly (p< 0.05) decreased; the X-rays and histomorphological observations suggested that the periodontal inflammation and periodontitis were alleviated compared to the control. CONCLUSIONS IgY showed significant effects on anti-inflammatory, anti-coaggregation activity, and protected against alveolar bone loss. Therefore, it had a beneficial effect on preventing experimental periodontitis caused by P. gingivalis.

Abstract
BACKGROUND AND OBJECTIVE Melatonin deficiency has been associated with obesity and systemic inflammation. This study aims to evaluate whether melatonin could interfere with the mechanisms of co-morbidity linking obesity and periodontitis. MATERIAL AND METHODS Twenty-eight male Wistar rats were randomly divided in 4 groups: control group (Con) (fed with standard diet); high-fat diet group (HFD) (fed with a diet containing 35.2% fat); Con group with induced periodontitis (Con-Perio) and HFD group with induced periodontitis (HFD-Perio). To induce periodontitis, the method of oral gavages with Porphyromonas gingivalis ATCC W83K1 and Fusobacterium nucleatum DMSZ 20482 was used. Circulating melatonin levels were analyzed by multiplex immunoassays. Periodontitis was assessed by alveolar bone loss (micro-computed tomography and histology) and by surrogate inflammatory outcomes (periodontal pocket depth, modified gingival index and plaque dental index). RESULTS Plasma melatonin levels were significantly decreased (P < .05) in the obese rats with periodontitis when compared with controls or with either obese or periodontitis rats. Alveolar bone loss increased 27.71% (2.28 µm) in HFD-Perio group compared with the Con group. The histological analysis showed marked periodontal tissue destruction with osteoclast activity, particularly in the HFD-Perio group. A significant negative correlation (P < .05) was found between periodontal pocket depth, modified gingival index and circulating melatonin levels. CONCLUSION Obese and periodontitis demonstrated significantly lower melatonin concentrations when compared with controls, but in obese rats with periodontitis these concentrations were even significantly lower when compared with either periodontitis or obese rats. These results may indicate that melatonin deficiency could be a key mechanism explaining the co-morbidity effect in the association between obesity and periodontitis.

Abstract
BACKGROUND Periodontitis is a chronic disease that due to an intense inflammatory response triggers systemic changes such as hepatic alterations. This study aimed to compare hepatic damage in rats that received experimental periodontitis at one or two periodontal sites with ligatures. MATERIAL AND METHODS Eighteen rats were separated into three groups: control, without ligature; periodontitis 1, with one ligature; and periodontitis 2, with two ligatures. The following parameters were assessed: gingival bleeding index, probing pocket depth, tooth mobility, alveolar bone loss, malondialdehyde (MDA) and myeloperoxidase (MPO) activity in periodontal tissue; histopathological evaluation of hepatic tissue (steatosis score); glutathione levels (GSH), MDA, MPO, cholesterol and triglycerides in the liver; and serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). RESULTS Periodontal evaluation data showed that the periodontitis model worked well. The groups with periodontitis did not differ significantly in relation to MPO activity and MDA levels in the gingival samples, but they were significantly different when compared with the control group. Steatosis was observed in the histological analysis of the groups with periodontitis, but between the periodontitis groups, two ligatures did not cause increase in steatosis score. The levels of GSH, MDA, total cholesterol and triglycerides in the hepatic tissue were not altered between groups with periodontitis, but they showed significant differences in comparison with the control group. The activity of MPO in hepatic tissue and serum levels of AST and ALT did not present significant difference among the three groups. CONCLUSION In conclusion, our results demonstrated that one or two ligatures inducing periodontitis were both sufficient to cause fatty liver. Steatosis caused by two ligatures did not present larger extension and severity than steatosis caused by one ligature.

Abstract
Local drug delivery systems have been proposed for the treatment of periodontitis, and Hylotelephium purpureum may be a suitable agent for use in such a system. The present study aimed to formulate a Hylotelephium purpureum gel (HPG) and evaluate the anti-inflammatory activity and antinociceptive effects of Hylotelephium purpureum and to assess the duration of action and efficacy of HPG in the treatment of experimental periodontitis in a KM mouse model. First, an acute toxicity study was performed, and secondly, xylene-induced mouse-ear edema, acetic acid-induced mouse peritoneal capillary permeability and carrageenan-induced hind-paw edema tests were used to investigate the anti-inflammatory activity of the gel. The acetic acid-induced writhing response and hot-plate tests were used to evaluate the antinociceptive activity. The therapeutic effects of HPG in experimental periodontitis were evaluated and minimum inhibitory concentration of the gel was determined. The results showed that intragastrically administration of 80 ml/kg of HPG produced no toxic effects. There were statistically significant changes in gingival indexes and sulcus bleeding indexes in the high-dose HPG-treated group. The serum levels of superoxide dismutase and glutathione peroxidase were significantly heightened, while the level of malondialdehyde was decreased. HPG exhibited 32.7% inhibition of edema, and altered the peritoneal capillary permeability in mice. The gel had relatively good bacteriostatic and bactericidal effects. It also exhibited antinociceptive activity, as demonstrated by the acetic acid-induced writhing response test and hot-plate test. In summary, the present study demonstrates that HPG is effective in the treatment of experimental periodontitis.

Abstract
A specific, sensitive and stable high-performance liquid chromatography (HPLC)-based analytical method was established to determine the level of pefloxacin mesylate (PM) in the plasma and various tissues of chickens. Chickens were randomly assigned to 12 equal experiment groups, including 11 treatment groups and one control group. The chickens in the treatment groups received oral administration of PM and were sacrificed at different pre-determined time points, with their blood and various organs harvested, extracted and analyzed by HPLC to quantify the level of the residual antibiotic. Method validation studies indicated that the HPLC measurement showed excellent precision, reproducibility, stability and robustness. The obtained pharmacokinetic parameters suggested that PM reached peak levels in various tissues within 1-2 h after its oral administration, and was mainly concentrated in liver and kidney. The antibiotic was also found to be cleared from chicken crureus, brain, testes, ovaries and pancreas at higher rates compared with other organs. Overall, the rapid accumulation of PM could at least be partially attributed to its relatively slow organ clearance. These results could serve as a useful guidance for the rational use of PM and other quinolone-derived antimicrobials in the treatment of infectious diseases in chickens and other animals.

Abstract
Chronic periodontitis (CP) is one of the most common oral diseases, which causes alveolar bone absorption and tooth loss in adults. In this study we aimed to investigate the potential of plumbagin (PL), a widely-investigated active compound extracted from the traditional Chinese herb Plumbago zeylanica L in treating CP. Human periodontal ligament stem cells (PDLSCs) were used for in vitro studies, whereas an animal model of CP was established in SD rats by ligation+Porphyromonas gingivalis (Pg) stimulation. The rats were injected with PL (2, 4, and 6 mg·kg-1·d-1, ip) for 4 weeks. Treatment of PDLSCs with TNF-α (10 ng/mL) markedly stimulated the expression of the proinflammatory cytokines TNF-α, IL-1β and IL-6, as well as the chemokines CCL-2 and CCL-5, which were dose-dependently suppressed by co-treatment with PL (1.25-5 μmol/L). Furthermore, PL (3.75 μmol/L) markedly suppressed TNF-α-induced activation of the MAPK, NF-κB and JAK/STAT signaling pathways in PDLSCs. In consistence with the in vitro studies, PL administration significantly decreased the expression of TNF-α, IL-1β and IL-6 in gingiva of the rat with CP, with the dosage 4 mg·kg-1·d-1 showing the best anti-inflammatory effect. Moreover, PL administration decelerated bone destruction in the rat with CP, evidenced by the aveolar bone loss (ABL) and H&E staining results. In conclusion, PL suppresses CP progression in rats by downregulating the expressions of TNF-α, IL-1β and IL-6 and inhibiting the MAPK, NF-κB and JAK/STAT signaling pathways.

Abstract
BACKGROUND Damage caused by periodontitis not only affects periodontal tissues, but also increases the severity of various illnesses such as rheumatoid arthritis, diabetes, and liver diseases. The aim of this study is to investigate the association between induced periodontitis and damage caused through its systemic effects on the liver. METHODS Twenty rats were divided into two groups: control and periodontitis. The following parameters were evaluated: gingival bleeding index (GBI), probing depth (PD), myeloperoxidase (MPO) activity, alveolar bone loss (ABL) for periodontal tissues; histopathologic examination of gingival and liver tissues; immunohistochemistry to cells positive for neural/glial antigen 2 (NG2) expressed in hepatic pericytes, glutathione (GSH), and malondialdehyde (MDA) concentrations in liver; and serum levels of alanine aminotransferase and aspartate aminotransferase. RESULTS GBI, PD, MPO, ABL, and histopathologic examinations demonstrated the development of periodontitis. There was a significant increase in microvesicular steatosis accompanied by a marked reduction in NG2+ pericytes in the periodontitis group compared with the control group. The periodontitis group had significantly lower GSH and higher MDA concentration in the liver compared with the control group. CONCLUSIONS The present study results link the systemic effects of induced periodontitis with changes in hepatic tissues such as microvesicular steatosis, likely caused by an increase in oxidative stress and lipid peroxidation. The findings from the present study implicate an association between a decrease of pericytes and liver disease caused by ligature-induced periodontitis in rats.

Abstract
Introduction: One of the options for the treatment of periodontitis is local drug delivery systems (LDD). Tulsi (Ocimum sanctum), a traditional herb, has many uses in medicine. It could be a suitable agent as LDD for the treatment of periodontitis. Aim: The aim was to formulate, evaluate the anti-inflammatory activity; assess duration of the action and the efficacy of 2% tulsi (O. sanctum) gel in the treatment of experimental periodontitis in Wistar Albino rat model. Settings and Design: Thirty six Wistar albino rats were randomly assigned to 3 groups. Periodontitis was induced using ligature model. Group 1-control; Group 2-Plain gel and Group 3-2% tulsi (O. sanctum) gel. Materials and Methods: 2% tulsi (O. sanctum) gel were prepared. The anti-inflammatory activity and duration of action were assessed. Silk ligature 5-0 was used to induce periodontitis. Gingival index (GI) and probing pocket depth were measured. Treatment was done. The rats were sacrificed. Morphometric analysis was done using Stereomicroscope and ImageJ software. Statistical Analysis Used: ANOVA followed by Bonferroni's test, Wilcoxon's test for intergroup comparison, Mann-Whitney test for P value computation was used. The observations are mean ± standard deviation and standard error of the mean. P < 0.01 as compared to control was considered as statistically significant. Results: 2% tulsi (O. sanctum) gel showed 33.66% inhibition of edema and peak activity was noted at 24 h. There was statistically significant change in the GI and probing pocket depth. Morphometric analysis did not show any significant difference between groups. No toxic effects were seen on oral administration of 2000 mg/kg of Tulsi extract. Conclusions: 2% tulsi (O. sanctum) gel was effective in the treatment of experimental periodontitis.

Abstract
CONTEXT Local drug delivery (LDD) systems have been proposed for the treatment of periodontitis. Curcumin could be a suitable agent as LDD for the treatment of periodontitis. AIM To formulate, evaluate the anti-inflammatory activity and to assess the duration of the action and the efficacy of 2% curcumin gel in the treatment of experimental periodontitis in Wistar albino rat model. SETTINGS AND DESIGN Twenty-one Wistar albino rats were randomly assigned to three groups. Periodontitis was induced using ligature model. Group 1: Control; group 2: Plain gel, and group 3: 2% curcumin gel. MATERIALS AND METHODS About 2% curcumin gel was prepared. The anti-inflammatory activity and duration of action was assessed. Silk ligature 5-0 was used to induce periodontitis. Gingival index (GI) and probing pocket depth (PPD) were measured. Treatment was done. The rats were sacrificed. Morphometric analysis was performed using stereomicroscope and ImageJ software. STATISTICAL ANALYSIS USED Analysis of variance followed by Bonferroni's test, Wilcoxon's test for inter-group comparison, Mann-Whitney test for P value computation was used. The observations are mean ± standard deviation and standard error of the mean. P < 0.01 when compared to control was considered as statistically significant. RESULTS About 2% curcumin gel showed 42.98% inhibition of edema and peak activity was noted at 24 h. There was statistically significant change in the GI and PPD. Morphometric analysis did not show any significant difference between groups. No toxic effects were seen on oral administration of 2000 mg/kg of curcumin. CONCLUSIONS About 2% curcumin gel was effective in the treatment of experimental periodontitis.

Abstract
AIM The aim of the novel study was to check the efficacy of a locally applied 2%w/w nanoemulgel (NEG) of Ketoprofen (KP) in preventing the periodontitis, and was also checked NEG without KP to ensure the effect of eugenol in NEG as an oil phase. DESIGN For experimentally induced periodontitis, sterile silk ligatures (3/0) were placed around the crevices of the first left lower molar teeth of the male Wistar rats. During 8 weeks, all rats were fed with 10%w/v sucrose solution. The experimental assessment was carried out at 11 d after treatment of experimental periodontal disease (EPD) rats by various clinical parameters like gingival index (GI), tooth mobility (TM), alveolar bone loss (ABL), histological analysis, detection of TNF-α, and IL-1β in gingival tissue by ELISA and the roughness were measured by atomic force microscopy (AFM) in tapping modes. RESULTS After treatment, comparison studies with EPD were performed. NEG loaded with KP prevents significantly (p < 0.05) various parameters (GI, TM, and ABL), which were responsible for periodontitis. The histopathology of the periodontium showed that Group 3 (NEG loaded with KP) had a more significant reduction in inflammatory cell infiltration, alveolar bones resorption, and cementum (p < 0.05). In the topographical images, significant reduction in roughness of NEG loaded with KP was observed in comparison with EPD without treatment. CONCLUSION The study revealed the great synergistic potential of the combined NEG of an anti-inflammatory drug KP along with eugenol as the oil phase, which have potential antibacterial, analgesic, and anesthetic properties to combat periodontal disease.
