Abstract
BACKGROUND The number of malignancies increased alarmingly. Surgery constitutes one of the most efficient therapeutic modalities for the treatment of solid tumors. The neoplastic implant in surgical wound is a complication whose percentage of occurrence reported in the literature is variable, but sets with high morbidity and therapeutic difficulties. Protecting the wound is one of the recommended principles of oncologic surgery. AIM To evaluate the influence of wound protection in the development of tumor implantation. METHODS Sarcoma 180 tumor cells were used, with intraperitoneal inoculation in Swiss mice. After the establishment of neoplastic ascites, animals were randomized into two groups of 10, each group consisting of five males and five females. In both groups, laparotomy and manipulation of intra-abdominal organs was performed. In a group laparotomy was performed using the protection of the abdominal wound and the other group without it. On the 9th postoperative day macroscopic evaluation of the operative scar was performed, which was later removed for microscopic evaluation. RESULTS There was microscopic infiltration of tumor cells in the wound of all animals. However, the group that held the protection, infiltration was less intense when compared to the group without it. The infiltration was also more severe in females than in males of the same group. CONCLUSION Tumor infiltration into the wound was more intense in the group in which the protection of the surgical site was not performed, and in females when compared to males of the same group.

Abstract
PURPOSE Chitosan, a natural macromolecule, is widely used in medical and pharmaceutical fields because of its distinctive properties such as bactericide, fungicide and above all its antitumor effects. Although its antitumor activity against different types of cancer had been previously described, its mechanism of action was not fully understood. MATERIALS AND METHODS Coating of chitosan has been used in cell cultures with A375, SKMEL28, and RPMI7951 cell lines. Adherence, proliferation and apoptosis were investigated. RESULTS Our results revealed that whereas chitosan decreased adhesion of primary melanoma A375 cell line and decreased proliferation of primary melanoma SKMEL28 cell line, it had potent pro-apoptotic effects against RPMI7951, a metastatic melanoma cell line. In these latter cells, inhibition of specific caspases confirmed that apoptosis was effected through the mitochondrial pathway and Western blot analyses showed that chitosan induced an up regulation of pro-apoptotic molecules such as Bax and a down regulation of anti-apoptotic proteins like Bcl-2 and Bcl-XL. More interestingly, chitosan exposure induced an exposition of a greater number of CD95 receptor at RPMI7951 surface, making them more susceptible to FasL-induced apoptosis. CONCLUSION Our results indicate that chitosan could be a promising agent for further evaluations in antitumor treatments targeting melanoma.

Abstract
Bone defects caused by fractures or cancer-mediated destruction are debilitating. Chitosan is commonly used in scaffold matrices for bone healing, but rarely as a free drug. We demonstrate that free chitosan promotes osteoblast proliferation and osteogenesis in mesenchymal stem cells, increases osteopontin and collagen I expression, and reduces osteoclastogenesis. Chitosan inhibits invasion of endothelial cells, downregulating uPA/R, MT1-MMP, cdc42 and Rac1. Better healing of bone fractures with greater trabecular bone formation was observed in mice treated with chitosan. Chitosan induces apoptosis in osteotropic prostate and breast cancer cells via caspase-2 and -3 activation, and reduces their establishment in bone. Chitosan is pro-apoptotic in osteosarcoma cells, but not their normal counterpart, osteoblasts, or chondrosarcoma cells. Systemic delivery of chitosan does not perturb angiogenesis, bone volume or instinctive behaviour in pregnant mice, but decreases foetal length and changes pancreatic secretory acini. With certain controls in place, chitosan could be useful for bone trauma management.

Abstract
AbstractAcetaminophen (APAP) is the most commonly reported toxic ingestion in the world. Severe liver injury resulting from overdose or chronic use of APAP remains a significant clinical problem. In recent years, the mechanisms underlying liver injury caused by APAP have become much better understood. We have studied the protective effect of chitosan supplementation against APAP‐induced hepatotoxicity with respect to changes in the levels of total and lipid‐bound sialic acid in the serum and in the liver tissue and changes in the activity of diagnostic marker enzymes, lipid peroxidation, and ceruloplasmin oxidase enzyme in normal and experimental groups of rats. During the experimental period, chitosan (200 mg/kg body weight per day) was administered to APAP + chitosan‐treated rats by oral gavage. Results showed that treatment with APAP induced a significant increase in the serum alanine aminotransferase and alkaline phosphatase activities, in total and lipid‐bound sialic acids levels, and in the liver lipid peroxide content. The administration of chitosan significantly prevented APAP‐induced alterations in the levels of diagnostic marker enzymes, total sialic acid, lipid‐bound sialic acid, and malondialdehyde in the experimental groups of rats. Furthermore, chitosan administration increased the activity of ceruloplasmin oxidase. In conclusion, our results suggest that chitosan has a protective effect on APAP‐induced hepatic injury in rats. The study sheds light on the therapeutic potential of chitosan in an APAP‐induced hepatotoxicity model.

Abstract
A polysaccharide-rich substance isolated from black currant, named cassis polysaccharide (CAPS), was partially digested with beta-galactosidase from Aspergillus oryzae and its immunostimulatory activity was investigated. The in vitro cytokine-inducing effect of CAPS on RAW264 cells was gradually decreased along with lowering of the average MW of CAPS. In vivo, partially digested CAPS with a mean MW of approximately 20,000 showed the most potent antitumor activity against Ehrlich carcinoma in mice.

Abstract
Mitomycin C (MMC) has shown potent efficacy against a wide spectrum of cancers and is clinical first choice in superficial bladder tumors. However, intravesical chemotherapy with MMC has been ineffective due to periodical discharge of the bladder and instability of this drug in acidic pH, both resulting in high rate of tumor recurrence and insufficiency to prevent progression. Nanocarriers may be a promising alternative for prolonged, effective and safe intravesical drug delivery due to their favorable size, surface properties and optimum interaction with mucosal layer of the bladder wall. Hence, the aim of this study was to evaluate and optimize cationic core-shell nanoparticles formulations (based on chitosan (CS) and poly-ϵ-caprolactone (PCL)) in terms of antitumor efficacy after intravesical administration in bladder tumor induced rat model. Antitumor efficacy was determined through the parameters of survival rate and nanoparticle penetration into the bladder tissue. Safety of the formulations were evaluated by histopathological evaluation of bladder tissue as well as observation of animals treated with MMC bound to nanoparticles. Results indicated that chitosan coated poly-ϵ-caprolactone (CS-PCL) nanoparticles presented the longest survival rate among all treatment groups as evaluated by Kaplan-Meier plotting. Histopathological evaluation revealed that cationic nanoparticles were localized and accumulated in the bladder tissue. As intravesical chemotherapy is a local therapy, no MMC was quantified in blood after intravesical instillation indicating no systemic uptake for the drug which could have subsequently led to side effects. In conclusion, core-shell type cationic nanoparticles may be effective tools for the intravesical chemotherapy of recurrent bladder tumors.

Abstract
This study was performed to investigate the possible involvement of polyamines in the development of cervical cancer. The objective of the present study was therefore to find the specific polyamine indicators, which could be used as useful markers for the early determination of cervical cancer. A simple method for the simultaneous determination of plasma concentrations of five polyamines in normal and U14 model mice was developed by using HPLC-MS. The samples were derivatized by benzoyl chloride. The derived polyamines were separated on a C18 column by a gradient elution with methanol–water, and then detected with HPLC-MS. The results showed that all polyamine levels in the U14 model mice were higher than those in normal ones. The cadaverine, putrescine and 1, 3-diaminopropane levels were significantly higher in U14 model mice plasma than those in normal mice plasma, especially the putrescine and 1, 3-diaminopropane (P<0.01). The cadaverine, putrescine and 1, 3-diaminopropane levels were significantly higher in U14 mice model urine than those in normal mice urine, especially the cadaverine and 1, 3-diaminopropane (P<0.01). Putrescine, cadaverine and 1, 3-diaminopropane might be the indicators of the cervical cancer.

Abstract
The pharmacokinetic properties of chitosan nanoparticles have been shown to mainly depend on its particle size. The aim of this study was to concurrently evaluate and model the effective parameters, namely, chitosan concentration, buffer pH, amplitude and time of sonication, on the particle size of chitosan nanoparticles. Chitosan solutions were prepared and sonicated with different values for the above mentioned parameters. The data were then modeled using artificial neural networks (ANNs). The results illustrated that all four input parameters affect the size of prepared chitosan nanoparticles. While a reverse effect was observed between the size and the buffer pH as well as time and amplitude of sonication, the concentration was found to directly influence the particle size. The optimum condition to obtain the minimum size of nanoparticles in the range of 50-200 nm was found to be high values of pH and sonication time (i.e. approximately 4.9 and 500 s, respectively) and amplitude values of more than ~55.

Abstract
To overcome the recurrence problem in bladder tumours; nanoparticles with positive surface charge may improve interaction with biological membranes for intravesical administration. The aim of this study was to design, develop and evaluate (in vitro-in vivo) cationic nanoparticles based on chitosan, poly-L-lysine or polycaprolactone for the effective intravesical delivery of chemotherapeutic agent MMC in a rat model. Poly-L-lysine-coated polycaprolactone nanoparticles and chitosan-coated polycaprolactone nanoparticles were prepared by the double emulsion technique. Chitosan nanoparticles were prepared by ionic gelation. It was found that nanoparticle formulations of 160-320 nm in size can be produced in 14-35% encapsulation efficiency. Variability in the particle size of nanoparticles depended on the preparation method. Encapsulation was increased by two-fold for CS-PCL as a result of the double emulsion technique. Commercial MMC product in solution form and cationic nanoparticle formulations were compared for in vivo bladder retention properties and effect of formulations on urine volume.

Abstract
N,N,N-Trimethyl chitosan chloride is capable of forming nanocomplexes with protein through ionotropic gelation. A monoclonal antibody, raised against human liver heparan sulfate proteoglycan and specifically inhibiting hepatocellular carcinoma in vitro, was prepared in nanocomplexes of this modified chitosan. The smallest nanocomplexes (59 ± 17 nm, zeta-potential 16.5 ± 0.5 mV) were obtained at polysaccharide:antibody ratios of 5:0.3. Spherical particles with a smooth surface and compact structure having a mean diameter of ~11.2 ± 0.09 nm were investigated by Atomic Force Microscopy. Cellular uptake of fluorescently labeled nanocomplexes was studied in mouse monocyte models of cancer and normal cells. External and internal fluorescence was analyzed by flow cytometry. The results demonstrate that the nanocomplexes could enter cells and were retained for a longer period of time in cancer cells where they exhibited greater toxicity. These nanocomplexes appear safe and could potentially enhance the half-life of added antibodies.

Abstract
Chitin and its derivatives-as a potential resource as well as multiple functional substrates-have generated attractive interest in various fields such as biomedical, pharmaceutical, food and environmental industries, since the first isolation of chitin in 1811. Moreover, chitosan and its chitooligosaccharides (COS) are degraded products of chitin through enzymatic and acidic hydrolysis processes; and COS, in particular, is well suited for potential biological application, due to the biocompatibility and nontoxic nature of chitosan. In this review, we investigate the current bioactivities of chitin derivatives, which are all correlated with their biomedical properties. Several new and cutting edge insights here may provide a molecular basis for the mechanism of chitin, and hence may aid its use for medical and pharmaceutical applications.

Abstract
Poly(γ-benzyl-L-glutamate) (PBLG) derivatives are synthetic polypeptides for preparing nanoparticles with well controlled surface properties. The aim of this paper was to investigate the biodistribution of pegylated PBLG in rats. For this purpose, nanoparticles were prepared by a nanoprecipitation method using mixtures of different PBLG derivates, including a pegylated derivate to avoid mononuclear phagocyte system uptake. The morphology, size distribution, and surface charge of the nanoparticles were investigated as a function of the amount of polymer employed for the preparation. Moderately polydispersed nanoparticles (polydispersity index less than 0.2) were obtained. Their size increased with polymer concentration. The zeta potential values were negative whatever the formulations. The availability of polyethylene glycol chains on the nanoparticles’ surface was confirmed by measuring the decrease in bovine serum albumin adsorption. For in vivo distribution studies, pegylated and nonpegylated nanoparticles were prepared with polymer mixtures containing PBLG-fluorescein isothiocyanate and imaged by fluorescence microscopy to measure their accumulation in liver and spleen tissues of rats after intravenous administration. Injection of stealth formulations resulted in negligible fluorescence in liver and spleen compared with nonpegylated formulations, which suggests that these nanoparticles are promising candidates as a stealth-type long-circulating drug carrier system and could be useful for active targeting of drugs while reducing systemic side effects.

Abstract
Chitosan nanoparticles (CS-NPs) were prepared by ionic gelation method using carboxymethyl chitosan and chitosan hydrochloride as carriers of tea polyphenols. The characteristics of chitosan-coated tea polyphenols nanoparticles (CS-TP NPs) were determined by using transmission electron microscopy (TEM) and FT-IR spectroscopy. It was found that the synthesized CS-TP NPs were non-spherical in shape with an average size of 407±50nm. Meanwhile, the drug content and encapsulation rate of the nanoparticles was 8-16% and 44-83%, respectively. These CS-TP NPs also demonstrated sustained release of tea polyphenols in PBS. The antitumor of CS-TP NPs towards HepG2 cancer cells was investigated. The result showed that CS-TP NPs retained significant antitumor activities.

Abstract
The purpose of this research was to develop polylactic-co-glycolic acid (PLGA) nanospheres surface modified with chitosan (CS). Mitoxantrone- (MTO-) loaded PLGA nanospheres were prepared by a solvent evaporation technique. The PLGA nanospheres surface was modified with CS by two strategies (adsorption and covalent binding). PLGA nanospheres of 248.4+/-21.0 nm in diameter characterized by the laser light scattering technique, scanning electron microscopy (SEM) are spherical and its drug encapsulation efficiency is 84.1+/-3.4%. Zeta potential of unmodified nanospheres was measured to be negative -21.21+/-2.13 mV. The positive zeta potential of modified nanospheres reveals the presence of CS on the surface of the modified nanospheres. Modified nanospheres were characterized for surface chemistry by X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR). FT-IR spectra exhibited peaks at 3420 cm(-1) and 1570 cm(-1), XPS spectra shows the N 1s (atomic orbital 1s of nitrogen) region of the surface of the nanospheres, corresponding to the primary amide of CS. In vitro drug release demonstrated that CS-modified nanospheres have many advantages such as prolonged drug release property and decreased the burst release over the unmodified nanospheres, and the modified nanospheres by covalent binding method could achieve the release kinetics of a relatively constant release. These data demonstrate high potential of CS-modified PLGA nanospheres for the anticancer drug carrier.

Abstract
PURPOSE We determined the adhesion of particles with phenyl, carboxylic acid (COOH), amine, dialkyl phosphonate, ester, and hydroxyl groups to malignant and nonmalignant cells, in order to better design drug delivery systems (DDS) for malignant cells. METHODS Living mouse melanoma skin (B16F10) and noncancerous mouse fibroblast (L929) cells, and an Atomic Force Microscope were used to determine the adhesion strengths. RESULTS The measurement of the particles against B16F10 cells showed that COOH had the highest average maximum adhesion force (<F (admax)>) and a large standard deviation (std), and phenyl had the lowest <F (admax)> and a lower std. The high <F (admax)> and std suggested that COOH was binding the strongest to malignant cells, and to groups overexpressed on malignant cells. In the case of L929 cells, <F (admax)> of phenyl and COOH were higher and lower, respectively, than those of the B16F10 cells. Additionally, Phenyl and COOH gave a lower std than that for the B16F10 cells. These results suggest that the lower binding of COOH to the nonmalignant cells was due to the lower number of groups that were overexpressed in the malignant cells. CONCLUSIONS Our results suggest that COOH is the best group for malignant cell targeting DDS systems.

Abstract
Chitosan nanoparticles (CNP), a kind of widely used drug carrier, have shown potent cytotoxic effects on various tumour cell lines in vitro and in vivo. This study sought to evaluate the antitumour effect of CNP on growth of human hepatocellular carcinoma (BEL7402) and the possible mechanisms involved. Cells were grown in the absence and presence of various concentrations of CNP with mean particle size of about 40nm. Cell viability, ultrastructural changes, surface charge, mitochondrial membrane potential, reactive oxygen species (ROS) generation, lipid peroxidation, DNA fragmentation and fatty acid composition were analysed by MTT assay, electron microscopy, zetasizer analysis, flow cytometry, spectrophotometric thiobarbituric (TBA) assays, DNA agarose gel electrophoresis and GC/MS respectively. For in vivo experiments, male BABL/c nude mice were implanted with BEL7402 cells subcutaneously to establish human hepatoma model. Chitosan, saline, and CNP with different mean particle size (40, 70 and 100nm) were administrated by oral administration (1mg/kg body weight). Tumour and body weight were measured, morphologic changes of tumour and liver tissues were studied under electron microscope. In vitro, CNP exhibited high antitumour activities with an IC(50) value of 15.01microg/ml, 6.19microg/ml and 0.94microg/ml after treatment for 24h, 48h and 72h respectively. CNP could induce cell necrosis observed by electron microscope and DNA fragmentation. The antitumour mechanism was mediated by neutralisation of cell surface charge, decrease of mitochondrial membrane potential and induction of lipid peroxidation. The tumour growth inhibitory rates on BEL7402 cells in nude mice treated with chitosan and CNP with different mean particle size (40, 70 and 100nm) were 24.07%, 61.69%, 58.98% and 34.91% respectively. Typical necrotic morphological changes of tumour tissues and no liver abnormalities were found under electron microscope. In this paper, results show a strong antitumour effect of CNP on human hepatoma cell line BEL7402 in vitro and in vivo. These findings suggest that CNP could be a kind of promising agent for further evaluations in the treatment of hepatocellular carcinoma.
