RESUMO
Background: Malaria is still one of the most severe public health problems worldwide. The development of treatment, prevention, and control of malaria is one of the substantial problems in the world. Aims: To investigate the in vitro antimalarial activity of Syzygium cumini methanol fruit fraction. Methods: Syzygium cumini L fruit powder was macerated with methanol (PA) and the extract obtained was fractionated using the liquid-liquid partition method with n-hexane, ethyl acetate, butanol, chloroform, methanol, and water solvents. In vitro antimalarial assay was conducted using the culture of Plasmodium falciparum 3D7 strain culture that had reached >5% growth and was examined for IC50 values using a 24-well microplate in duplicate. Each treatment and control well contained 1,080 µl of complete media. Well, number 1 was added with 120 µl fraction, and then the solution was diluted until it reached 0.01, 0.1, 1, 10, and 100 µg/ml the final concentration in the microtiter well. The control only contained complete media and infected erythrocytes without the addition of anti-malarial drugs. The microplate was incubated for 48 hours. After 48 hours, a thin blood smear was made fixed with methanol and stained with 20% Giemsa for 20 minutes to determine the IC50 value by plotting sample concentrations and percentage of parasitemia in Excel. Results: The IC50 values of ethyl acetate fraction, n.hexane fraction, butanol fraction, and water fraction were 1.189, 76.996, 1,769, and 15.058 µg/ml, respectively. Whereases the IC50 values of C1 fraction (mix fraction from chloroform: methanol 100:0 and 90:10) and C4 fraction (mix fraction from chloroform: methanol 20:80, 10:90, and 0:100) were 100.126 and 1.015 µg/ml, respectively. The results showed that the IC50 value of ethyl acetate, butanol, and C4 fraction were lower than 10µg/ml and were considered as good activity (strong antimalarial activity). Conclusion: The ethyl acetate, butanol and C4 subfraction from S. cumini fruit have the potential to be developed as an antimalarial agent.

Plants have profound therapeutic benefits, more economical treatments, fewer side effects, and a relatively cheap cost, making them a source of drugs for protective, preventative, curative, or conducive purposes and creating novel phytomedicines. Plant derived medicines are relatively safe compared to synthetic medicines. Many plants have proved to successfully aid in the treatment of diabetes including Filago hurdwarica (Wall. ex DC.) Wagenitz. The current investigations were therefore designed to assess the phytochemical, antioxidant, antidiabetic, and antihyperlipidemic activities of F. hurdwarica. The phytochemical investigations and antioxidant activities of different extracts were carried out using standard chemical tests, DPPH, and H2O2 scavenging assays. F. hurdwarica plant extract in Hydromethanolic solution were prepared by Soxhletation method and stored in refrigerator at 4°C for two days before use. Swiss Albino mice were made diabetic by a single dose of alloxan (150 mg/kg). Hydromethanolic plant extract and fractions of F. hurdwarica were screened for antidiabetic activity and given to the alloxan-induced diabetic mice at a concentration of 150-250 mg/kg of body weight in different groups of 6 diabetic mice each orally once a day for 15 days. Glibenclamide is also given to another group to as a standard drug to support the result at a dose of 10 mg/kg of body weight orally once a day for 15 days. Blood glucose levels and body weights of mice were measured on 0, 4, 7, 11 and 15th days. The study found that the extract was safe up to the dose level of 2000 mg/kg and the dose response effect of chloroform extract (150-250 mg/kg) of F. hurdwarica showed expressive antihyperglycemic effects and also improved other altered biochemical parameters associated with diabetes. The FTIR and XRD spectra demonstrated the occurrence of phenols, alcohols, alkenes, alkyl halides, ketones, and aromatic compounds and confirmed the amorphous nature of the extract. GC-MS spectral analysis showed the tentative presence of 31 phytochemical constituents in the chloroform extract of F. hurdwarica with different retention time. To conclude, the chloroform extract (250 mg/kg) of F. hurdwarica revealed considerable antioxidant, antihyperglycemic, and antihyperlipidemic potential and is safe for treating diabetes and related complications.

Cancer is one of the most challenging diseases in the modern era for the researchers and investigators. Extensive research worldwide is underway to find novel therapeutics for prevention and treatment of diseases. The extracted natural sources have shown to be one of the best and effective treatments for cell proliferation and angiogenesis. Different approaches including disc potato model, brine shrimp, and chorioallantoic membrane (CAM) assay were adopted to analyze the anticancer effects. Habenaria digitata was also evaluated for MTT activity against NIH/3T3 cell line. The dexamethasone, etoposide, and vincristine sulfate were used as a positive control in these assays. All of the extracts including crude extracts (Hd.Cr), saponin (Hd.Sp), n-hexane (Hd.Hx), chloroform (Hd.Chf), ethyl acetate (Hd.EA), and aqueous fraction (Hd.Aq) were shown excellent results by using various assays. For example, saponin and chloroform have displayed decent antitumor and angiogenic activity by using potato tumor assay. The saponin fraction and chloroform were shown to be the most efficient in potato tumor experiment, demonstrating 87.5 and 93.7% tumor suppression at concentration of 1000 µg/ml, respectively, with IC50 values of 25.5 and 18.3 µg/ml. Additionally, the two samples, chloroform and saponins, outperformed the rest of the test samples in terms of antiangiogenic activity, with IC50 28.63 µg/ml and 16.20 µg/ml, respectively. In characterizing all solvent fractions, the chloroform (Hd.Chf) and saponin (Hd.Sp) appeared to display good effectiveness against tumor and angiogenesis but very minimal activity against A. tumefaciens. The Hd.Chf and Hd.Sp have been prospective candidates in the isolation of natural products with antineoplastic properties.

Men with diabetes have negative effects on reproduction that causes sexual dysfunction. Medicinal plants are non-toxic and much safer than synthetic drugs because regular use of synthetic drugs shows long-term side effects. Curcuma amada (Roxb) is a medicinal plant used in Ayurveda and Unani medicinal systems in India. The goal of this study is to rummage the potential efficiency of the most potent solvent fraction of effective extract of hydro-methanol 60:40 of C. amada rhizome on male gonadal hypofunction in streptozotocin-induced diabetic rat. Diabetes-induced testicular hypofunction was evaluated by glycemic, spermiological, biochemical, genomic, flow cytometric, and histology of testicular tissue. The n-hexane, chloroform, ethyl-acetate, and n-butanol solvent fractions of the said extract were administrated for 4 weeks at 10 mg dose/100 g body weight/day. Among all the used fractions, the ethyl-acetate solvent fraction-treated group showed maximum recovery in serum insulin (177.42%), sperm count (92.84%), sperm motility (97.15%), and serum testosterone (164.33%). The diabetic rats treated with ethyl-acetate solvent fraction also exhibited the maximum resettlement in flow cytometric analysis of sperm viability (55.84%) and sperm mitochondrial integrity (149.79%), gene expression patterns of key markers for androgenesis (Δ5, 3ß-HSD 87.50%, and 17ß-HSD 74.66%) and apoptosis (Bax 44.63%, Bcl-2 54.03%, and Caspase-3 35.77%) along with testicular histology. The ethyl-acetate fraction contains alkaloids, flavonoids, and polyphenols where all of these components are not present in other fractions, may be the most effective cause for the recovery of diabetes-linked oxidative stress-mediated testicular hypofunctions. PRACTICAL APPLICATIONS: Nowadays worldwide, the use of synthetic drugs are reduced due to their toxic effect. At present, synthetic drugs are replaced by several herbal drugs, the natural source of medicine which has many therapeutic values. C. amada has strong antioxidant activity due to the presence of bio-active compound(s) that can able to manage streptozotocin-induced diabetes linked to oxidative damage of male gonadal organs. Therefore, these bio-active compound(s)-containing said medicinal plant may use as a good source of antioxidative food in the food industry as nutraceuticals and in pharmaceutical industries for the development of the herbal drug to manage diabetes-linked male gonadal hypofunctions. At present, WHO also gives emphasis for developing one drug-multi-disease therapy. From such a viewpoint, this active fraction-containing phytomolecules may have corrective efficacy against diabetes as well as oxidative stress-linked testicular complications.

Leishmaniasis is a vector-borne disease that is caused by the protozoa of Leishmania genus. Leishmaniasis is endemic in tropical, subtropical, and large areas of the Mediterranean basin, and covers a total of 98 countries worldwide. It is estimated, according to the World Health Organization (WHO) data, that approximately 350 million people are at risk in these areas, and approximately 12 million people are infected. Increased drug resistance has been documented lately, in the treatment of leishmaniasis which causes almost 1.2 million new cases annually. Thus, interest in plant-derived active substances has increased in recent years, and new anti-leishmanial agents are investigated with in vitro studies. The aim of the present study was to investigate the anti-leishmanial effects of Prangos ferulacea and Ferula orientalis plant extracts collected from the rural areas of Sirnak province against Leishmania tropica. The water, chloroform, and ethanol extracts of the roots, stems, and fruits of P.ferulaceae and F.orientalis plants were obtained, and the cytotoxic activity tests of the extracts were performed. L.tropica isolate obtained from the Parasite Bank in Manisa Celal Bayar University in Turkey (MHOM/TR/2012/CBCL-LT) was grown on NNN and RPMI 1640 broth medium. The cytotoxicity of each extract on the L.tropica isolate was evaluated with the XTT test. Amphotericin B (AmpB) was used as the positive control, and the IC50 values were determined. The lowest IC50 values of the plant extracts were found to be as follows: P.ferulaceae root chloroform extract 36 µg/ml and fruit chloroform extract 20 µg/ml, F.orientalis root ethanol extract 2.5 µg/ml, and fruit ethanol extract 48 µg/ml, stem chloroform extract 24 µg/ml, and fruit chloroform extract 3.1 µg/ml. It was also determined in our study that only P.ferulaceae root ethanol extract showed cytotoxic activity on the WI-38 fetal lung fibroblast cell line at 65.19 µg/ml at 72 hours. This is the first study that assessed the anti-leishmanial activities of P.ferulaceae and F.orientalis plants that grow in high altitude areas of our country. It was determined that P.ferulaceae root ethanol extract and fruit chloroform extract had the lowest IC50 values among the 18 plant extracts that we examined for their anti-leishmanial activities. The outcomes of this study will be useful in further studies for the determination of active compounds in P.ferulaceae and F.orientalis plant extracts.

Plants are a significant source for the development of new phytomedicines due to their great clinical benefits, efficiency, cost-effectiveness, fewer side effects, and more affordable therapies. Numerous plants used in traditional treatments, such as Cotinus coggygria Scop., have been effective in the treatment of diabetes mellitus (DM). Therefore, the study is aimed at assessing the phytochemical, antioxidant, and antidiabetic properties of C. coggygria. The hypoglycemic and hypolipidemic activity was evaluated in Swiss male Albino mice by administering an oral dose of 150-250 mg/kg of C. coggygria extracts in alloxan-induced diabetic mice for 15 days. The antioxidant activity and phytochemical composition of the extracts were assessed by using α, α diphenyl-ß-picrylhydrazyl (DPPH) and hydrogen peroxide scavenging assays and through standard chemical procedures. The effects of extracts on blood glucose, body weight, lipid profile, and biochemical parameters like total cholesterol (TC), triglyceride (TG), low-density lipids (LDL), high-density lipids (HDL), plasma insulin, liver glycogen, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), urea, and creatinine were determined according to standard procedures. The activities of antioxidant enzymes such as superoxide-dismutase (SOD), peroxidase (POD), and catalase (CAT) were also analyzed spectrophotometrically. The hypoglycemic and hypolipidemic effects with chloroform extracts of 250 mg/kg were found significant in the treatment of diabetes in alloxanised mice compared to the diabetic group. The haematological parameters such as TC, TG, HDL, LDL, creatinine, urea, AST, ALT, and ALP were significantly improved (p < 0.01) by the chloroform extract of 250 mg/kg compared to the diabetic group. Treatment for 15 days showed significant elevation (p < 0.01) of antioxidant enzymes. Fourier-transform infrared spectroscopic (FTIR) and gas chromatography-mass spectrometry (GC-MS), column chromatography (CC), and nuclear magnetic resonance (NMR) analyses tentatively identified different phytoconstitutents and metabolites in C. coggygria leaves, which have been reported to possess antihyperglycemic properties. In conclusion, the chloroform extract of 250 mg/kg of C. coggygria possesses significant hypoglycemic and hypolipidemic potential which may prove the claimed use of the plant in amelioration of diabetes and associated complications in folkloric medicine. Additional studies are required for the purification, characterization, and structural elucidation of bioactive compounds.

The toxic side effects of doxorubicin in cancer treatment are well established. Here we show that methanolic extract of the fungus Ganoderma applanatum offers protection against cardio- and hepatotoxicity induced by doxorubicin (DOX) in Dalton's Lymphoma Ascites (DLA) bearing mice. Treatment of DLA mice with 20 mg/kg of doxorubicin significantly increased the activities of serum toxicity markers including aspartate amino-transferase (AST), alanine amino-transferase (ALT) and lactate dehydrogenase (LDH). However, co-administration of doxorubicin (20 mg/kg) by intraperitoneal injection and G. applanatum (150 mg/kg) by oral gavage in DLA mice lowered the AST, ALT, and LDH activities when compared to DOX alone treatment. Treatment of DLA mice with DOX alone resulted in reduced GSH contents, and decreased the activities of glutathione-s-transferase (GST), catalase (CAT), and superoxide dismutase (SOD). Treatment of DOX-administered DLA mice with G. applanatum however increased the GSH content and elevated the activities of GST, CAT, and SOD. Among the various solvent extracts of G. applanatum, methanolic extract showed the highest phenolic (376.5 ± 15.24 mg GAE/g) and flavonoid (4717.79 ± 170.22 mg quercetin/g) contents compared to the aqueous (216.3 ± 7.33 mg GAE/g) and chloroform extracts (137.27 ± 1.03 mg GAE/g). Consistently, the methanolic extract was found to possess the highest free radical scavenging activities when compared to the aqueous and chloroform extracts as measured by ABTS and DPPH assays. Our results thus suggest that the protective roles of G. applanatum in DOX-induced toxicity could be an attribute of the antioxidant properties conferred by the high phenolic and flavonoid contents.

OBJECTIVE: this study aimed to evaluate the efficacy of local application of Carnoy's solution following the surgical excision of recurrent PGCG. PATIENTS AND METHODS: 40 patients who sought treatment for recurrent PGCG were included in this study. According to the type of treatment the patients were classified randomly into two equal groups. The lesions in all patients were excised down to the alveolar bone followed by aggressive curettage. Then only in group II, Carnoy's solution was applied for 5 min. Clinical follow-up was done for 1 year to evaluate the tissue healing. RESULTS: patients were 23 females and 17 males, with an average of 35.9years. Recurrent PGCGs occurred most commonly in fifth decade of life (25 %). Maxilla (57.5 %) was involved more than the mandible. The lesions were found posteriorly in 27cases and anteriorly in 13cases. The average size of the lesions was 2.9 cm. Histologically, foci of calcifications occurred in 12cases. Recurrence occurred in 5 cases: 4 in group I and 1 in group II. Bone healing was appropriate in all patients without sequestration. CONCLUSION: the use of Carnoy's solution following surgical removal of recurrent PGCG decreases their recurrence rates. The technique is safe, and conservative with low tissue morbidity.

Irritable bowel syndrome (IBS) is a world-wide disease prevalently in Western nations. It influences about 15% of the western populace, with a negative effect on the quality of life and furthermore on medical services costs. Anticholinergic antispasmodics are first line of treatment for discomfort or abdominal pain, particularly if unrelieved after alleviation of stoppage or antidiarrheal treatment. Otilonium bromide (OTB) is quaternary ammonium compound with action on distal GI tract as antispasmodic. It is utilized in the treatment of patients influenced by Irritable inside disorder (IBS) because of its particular pharmacokinetic and pharmacodynamic properties. OTB is poorly absorbed systematically was viable in contrast with different medications used for same purpose, for example, pinaverium bromide and mebeverine, with a good tolerability profile. The effects are long lasting, even after stopping the dosage regime for reduction of abdominal pain. In this review, an overview of mechanism of action, pharmacologic action, synthesis and particularly various analytical and bioanalytical methods are discussed. The analytical methods discussed are spectrophotometry including Near Infrared Spectroscopy (NIRS), chromatography and capillary electrophoresis methods are described with the range, limit of detection and quantification. The paper also provides details of scope of further extension of analytical methods. It was found that most of the analytical methods involves usage of toxic solvents e.g., methanol, acetonitrile, chloroform etc. posing risk to the analyst as well as environment.

PURPOSE: The therapeutic use of herbal medicines for the diseases, including cancer, is increasing due to their lower side effects. The present research evaluated the effect of Peucedanum chenur chloroformic extract (PCCE) on cell proliferation against HCT-116 human colorectal cancer cell line. METHODS: The cytotoxic effect of PCCE was evaluated by MTT assay. The activity of the Wnt/B-catenin pathway was assayed through measuring the expression of miR-135b, miR-21, and APC genes by real-time PCR. The flow cytometry and scratch tests were used to study the cell cycle and cell migration, respectively. Also, the antioxidant activity of PCCE was measured by DPPH and iron-chelating tests. RESULTS: The results showed the downregulation of miR-135b and miR-21 and overexpression of the APC gene. Furthermore, PCCE decreased the free radicals, cell migration, and cell proliferation. The antioxidant activity of PCCE was confirmed by standard tests. CONCLUSION: Altogether, our findings suggest that purified compounds of PCCE could be developed as a potent chemo-preventive drug for the treatment of CRC.

Bone metabolism disorders are characterized by an imbalance of bone resorption and formation in the bone remodeling process. Glucocorticoids that are used to treat kidney diseases exacerbate these disorders. P-selectin and galectin-3 are molecules involved in the sclerotic process in kidney, whereas bone resorption is regulated by the interaction between the nuclear factor activator kappa b receptor (RANK), its ligand (RANKL) and the RANKL decoy receptor osteoprotegerin (OPG). The aim of this study was to investigate the cellular and molecular mechanisms of disruption of bone remodeling regulation processes, reflected by intercellular mediators (RANKL, OPG, P-selectin and galectin-3) in chronic kidney disease experimental model treated with glucocorticoids. Rats were divided into four groups of 10 animals each. The first group, the control group, included intact animals. The second group consisted of rats with impaired bone remodeling resulting from chronic kidney disease (experimental group (CKD). The third group was a group of animals with impaired bone remodeling due to exposure to glucocorticoids (experimental group (GCs)). The fourth group consisted of rats with impaired bone remodeling in chronic kidney disease, followed by exposure to glucocorticoids (experimental group (CKD + GCs)). The effects of CKD and glucocorticoid were evaluated biochemically, histologically and by measuring bone density. An enzymelinked immunoassay was used to measure intercellular mediator levels in the serum. The bone density in the experimental groups was reduced compared to the control group. RANKL levels in animals of three experimental groups were higher than in intact animals. Serum levels of OPG were higher in CKD and GCs groups than in intact animals. At the same time, in the animals' blood serum of the CKD + GCs group, the levels of OPG were lower, than those in animals from the control group. The levels of galectin-3 in the serum of the experimental groups GCs and CKD + GCs were lower than in intact animals. The serum levels of galectin-3 in animals of the CKD group were higher than those in animals from the control group. The levels of P-selectin were lower in the serum of the GCs group than in intact animals. At the same time, the levels of P-selectin were higher in the CKD and CKD + GCs groups, than those in animals from the control group. In conclusion, the study of the complex system of bone remodeling regulation, which includes many factors and their interactions, may lead to the development of new methods for treating patients with chronic kidney disease in order to prevent osteoporosis in the future.

Las enfermedades metabólicas óseas se caracterizan por un desequilibrio en el proceso de remodelación ósea en los que participan mediadores tales como receptor del activador del factor nuclear- kappa- b (RANK), su ligando (RANKL) y la osteoprotegerina (OPG). Los glucocorticoides, recuentemente empleados en el tratamiento de la enfermedad renal crónica, exacerban este desequilibrio. En la enfermedad esclerótica renal, las moléculas de adhesión celular P-selectina and galectina-3 tienen un rol fundamental. El objetivo de esta trabajo fue estudiar las alteraciones en los mediadores de la remodelación ósea (RANKL, OPG, P-selectina and galectina-3) en un modelo de enfermedad renal crónica con tratamiento glucocorticoideo. Ratas Wistar hembras fueron divididos en 4 grupos: control (C); enfermedad renal crónica con afección de la remodelación ósea (ERC); animales con afección de la remodelación ósea expuestos a glucocorticoides (GC); enfermedad renal crónica con afección de la remodelación ósea tratados con glucocorticoides (ERC+GC). Los efectos de la ERC y los GC fueron evaluados bioquímicamente, histológicamente y por medición de la densidad ósea. RANKL, OPG, Pselectina and galectina-3 se cuantificaron en muestras de sangre venosa empleando enzimoinmuno análisis. En los 3 grupos experimentales la densidad ósea se evidenció reducida y los niveles séricos de RANKL elevados respecto al grupo control. Los niveles de OPG en los grupos ERC y GC fueron superiores mientras que en el grupo ERC+GC menores respecto a los animales controles. Galectina 3 plasmática en GC y ERC+GC se encontró reducida y aumentada en los animales ERC, en comparación con los animales controles. La concentración sérica de P-selectina sérica fue mayor en los grupos ERC y ERC+GC, y menor en los animales GC respecto a los niveles plasmáticos de los animales intactos. El avance del conocimiento sobre la regulación de la remodelación ósea a través de la interacción de mediadores sistémicos, en un futuro, puede conducir al desarrollo de nuevas estrategias terapéuticas para la prevención de la osteoporosis en pacientes con enfermedad renal crónica.

Background and Objective: Medicinal plants represent an important source of alternative medicine for the management of various diseases. The present study was undertaken to assess the potential of Lawsonia inermis ethanol (Li.Et) and chloroform (Li.Chf) extracts as memory-enhancing agents in experimental animals. Materials and Methods: Li.Et and Li.Chf were phytochemically characterized via gas chromatography-mass spectroscopy (GC-MS). Samples were tested for nootropic potentials at doses of 25, 50, 100, 200 mg/kg (per oral in experimental animals (p.o.)). Swiss albino mice of either sex (n = 210) were divided into 21 × 10 groups for each animal model. Memory-enhancing potentials of the samples were assessed using two methods including "without inducing amnesia" and "induction of amnesia" by administration of diazepam (1 mg/kg, intraperitoneally. Piracetam at 400 mg/kg (i.p.) was used as positive control. Cognitive behavioral models including elevated plus maze (EPM) and the passive shock avoidance (PSA) paradigm were used. Biochemical markers of oxidative stress such as glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) levels were analyzed in the brain tissue of treated mice. Results: In 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radicals scavenging assay, Li.Et and Li.Chf exhibited 70.98 ± 1.56 and 66.99 ± 1.76% inhibitions respectively at 1.28 mg/mL concentration. GCMS results revealed the presence of important phytochemicals. Both samples (Li.Et and Li.Chf) at 25 mg/kg (p.o.) dose significantly (p < 0.05) improved learning and memory as indicated by decline in transfer latency and increase in step down latency in EPM and PSA models respectively. Li.Et and Li.Chf at 25 mg/kg (p.o.) showed considerable increase in GSH (2.75 ± 0.018 ***), SOD (2.61 ± 0.059 ***) and CAT (2.71 ± 0.049 ***) levels as compared to positive and negative control groups. Conclusions: This study provides the preliminary clue that L. inermis may be a potential source of memory-enhancing and anti-oxidant compounds and thus warrant further studies.

While cataloguing the historical items in the Department of Anaesthesia, Addenbrooke's Hospital, Cambridge, UK, we discovered an unusual chloroform inhaler, which incorporated two air-inlet tubes in addition to its main inspiratory valve as well as a funnel on one of its lateral walls. An accompanying card stated that the device was thought to be a modification of Snow's inhaler, by James Robinson. It had been found among some old instruments in a General Practice in Huntingdon, Cambridgeshire, and had probably been acquired by an early practitioner named Dr. Newton, who qualified in 1851 and performed a lot of minor surgery in the practice. Using information published in books, medical journals, instrument catalogues, and other sources available in the public domain, we sought to confirm the identify of this inhaler and further investigate its provenance. Soon after the introduction of chloroform anesthesia in November 1847, James Robinson modified Snow's ether face-piece to produce an ingenious device for administering the vapor of chloroform. However, Robinson's inhaler did not include the air-inlet tubes, or funnels, which are an integral feature of the device found in the Addenbrooke's collection. Following further research, we formally identified our device to be of the type introduced by James Townley in 1862 for use with his "Anodyne mixture." We describe Townley's chloroform inhaler and provide an insight into the life and work of its inventor, as well as Dr. Newton and his son, who may have used the apparatus in the Cambridgeshire area.

The odontogenic keratocyst (OKC) is a recurrent cyst that has been recently reclassified from an odontogenic tumor to an odontogenic cyst. The aim of the present study was to investigate its treatment and address issues related to its association with nevoid basal cell carcinoma syndrome (NBCCS). Lesions from the cohort of patients included in the present study consisted of 40 OKCs, of which 27 lesions were treated by enucleation (GE) and 13 underwent decompression (GD). Complementary treatment occurred in 38 (95%) lesions, of which 10 underwent isolated peripheral ostectomy (GO) and 28 underwent peripheral ostectomy combined with Carnoy's solution (GC). Thirteen lesions were associated with NBCCS (GS), while the others (n=27) were non-syndromic lesions (GnS). The recurrence-free periods (RFP) in the sample groups were compared using the Kaplan-Meier function and log-rank test at a significance level of 5% (p < 0.05) and were used to calculate the cumulative risk of recurrence (CRR) in each postoperative year. During the follow-up period, which had a mean of 43.5 months (range: 12-102 months), six (15%) recurrences were diagnosed. There was no significant difference among the RFP for the compared groups (p > 0.05) or increased CRR for the decompression (15.4%) over five years. Application of Carnoy's solution did not increase the efficacy of the peripheral ostectomy, but was related to a CRR of 0% for the syndromic lesions over five years. Therefore, 1) decompression did not increase the recurrence risk; 2) peripheral ostectomy demonstrated a similar efficacy as the combination with Carnoy's solution; 3) the association of NBCCS did not seem to significantly influence OKC recurrence; and 4) syndromic lesions seem to behave in the same manner as non-syndromic lesions when submitted to complementary treatments.

INTRODUCTION AND OBJECTIVE: The keratocystic odontogenic tumor is a benign but aggressive neoplasm. As enucleation alone obtains high recurrence rates, some adjuvant treatments such as Carnoy's solution have been proposed. The aim of this study is to evaluate the reduction of recurrences with the use of Carnoy's solution as adjuvant in the treatment of keratocystic odontogenic tumors. MATERIAL AND METHODS: An electronic search in Pubmed (MEDLINE), ScienceDirect and Cochrane databases was conducted with the key words "odontogenic keratocyst", "keratocystic odontogenic tumor", "carnoy's solution", "treatment" and "enucleation". The inclusion criteria were clinical studies using Carnoy's solution as adjuvant for the treatment of keratocystic odontogenic tumors, published in English, including at least 10 patients. Articles with an unclear reporting of the treatment applied, nonhuman studies, case reports and lesions associated to Gorlin-Goltz syndrome were excluded. RESULTS: All the studies included were case series. The recurrence rate of enucleation ranged from 0% to 58.8%. With the only use of Carnoy's solution as adjuvant treatment to the enucleation, recurrences varied from 0% to 100%. The use of ≥ 2 adjuvant treatments reduced the range between 0% and 7.9%. CONCLUSIONS: The use of Carnoy's solution as adjuvant therapy for the treatment of keratocystic odontogenic tumor has a grade C recommendation.

This retrospective study aimed to investigate the recurrence rate of keratocystic odontogenic tumours (KCOTs) treated by enucleation and the application of Carnoy's solution, and to assess the surgical morbidities associated with this treatment. KCOTs treated using a standard protocol of enucleation and the application of Carnoy's solution between 1990 and 2013 were evaluated. One hundred and five KCOTS in 105 patients (54 male, 51 female) were analysed. The mean follow-up period was 86.6 months (range 24-313 months). The recurrence rate was 11.4%. A postoperative inferior alveolar nerve neurosensory deficit occurred in 30.1% of the mandibular cases, with 16% of these being permanent. The postoperative infection and fracture rates were 1.9% and 0.9%, respectively. Younger age, multilocular KCOTs, larger tumour size, and longer antero-posterior lesion length on the radiograph were found to be risk factors for recurrence. It is concluded that enucleation and the application of Carnoy's solution to treat KCOTs results in a relatively low recurrence rate and a low rate of surgical morbidities.

PURPOSE: To understand the frequency of use of Carnoy's solution, as a means of chemical curettage, for treating the keratocystic odontogenic tumor (KCOT). MATERIALS AND METHODS: A Web-based survey was distributed by e-mail to 6,880 members listed in the 2013 American Association of Oral and Maxillofacial Surgeons directory. RESULTS: Eight hundred nine participants across the United States responded to the survey (12% response rate). The most common procedures performed to definitively treat a KCOT were enucleation plus mechanical curettage (curette with or without peripheral ostectomy; 66%). Of the survey participants, 198 (25%) currently use Carnoy's solution, 111 (56%) of whom are using the solution with chloroform and 83 (42%) are using it without chloroform. CONCLUSION: Carnoy's solution remains a common method of chemical curettage for the definitive treatment of the KCOT. Carnoy's solution with and without chloroform is being used for chemical cautery.

Keratocystic odontogenic tumour is relatively rare benign tumour. It is characterized by its fast aggressive growth and high risk of recurrence. Treatment is always surgical: conservative (enucleation, marsupialization) or aggressive (enucleation followed by application of Carnoy's solution, cryotherapy; peripheral ostectomy or en block resection of the jaw). Authors analysed retrospectively 22 patients who fulfilled inclusion criteria, i.e. had odontogenic keratocystic tumour of mandible, wherein antero-posterior dimension was at least 30 mm, and the tumour penetrated into the surrounding soft tissues. All patients underwent tumour enucleation, in 11 patients Carnoy's solution was given into the bone cavity after enucleation. The recurrence rate in the evaluation at least 36 months after surgery was both patient groups the same: 45.4%.
