Abstract
Lung cancer is one of the most common malignancies in the world, and chemotherapy can have unfavorable side effects. The aim of the present study is to evaluate the therapeutic anticancer role of Moringa oleifera leaf extracts (MLE) in urethane-induced lung cancer in adult male albino rats as compared to standard chemotherapy. Rats were categorized into four groups (10 rats/group), including negative control rats, urethane lung cancer model rats, MLE-treated lung cancer rats, and cisplatin-treated rats. Estimation of lung index, some biochemical markers of oxidative stress, quantitative real-time polymerase chain reaction (qRT-PCR), and histopathology and transmission electron microscopy were performed. The lung index was significantly increased about one-fold in urethane lung cancer model rats, but it decreased after MLE treatment. Also, MLE was able to improve the induced changes in glutathione, superoxide dismutase, and malondialdehyde concentration to be 3.8 ± 0.4 mg/g, 900.6 ± 58 U/g, and 172 ± 24 nmol/g, respectively. Additionally, after MLE treatment, the expression of EGFR-mRNA increased by about 50%. Our light and electron microscopic examination revealed that urethane group showed abnormally distributed excessive collagen fibers and the development of papillary adenocarcinoma from hyperplastic Clara cells in the lumen of terminal bronchiole with bronchiolar wall thickening, alveolar collapse, and inflammation. MLE group has moderate amount of collagen fiber and absence of tumor mass and provided more or less restoration of normal lung histology. Moreover, MLE was able to ameliorate the induced changes in mucin and PCNA positive cells in the lung by 10.8 ± 2.3%. Collectively, the current study showed that MLE could be used as anticancer agents alleviating changes associated with lung cancer in a urethane-induced lung cancer bearing rats thereby representing alternative options to toxic chemotherapy.

Abstract
Potassium dichromate is widely used in various laboratory and industrial applications. Vitamin C and melatonin are well-known antioxidants. Study the microscopic and morphometric alterations in the thyroid gland in adult male albino rats after the administration of potassium dichromate for successive 2 months and also to assess the possible protective effect of vitamin C versus melatonin on these changes. Sixty adult male albino rats were randomly divided into four main groups. Group I (The control group). Group II received potassium dichromate (25 mg/kg/day) dissolved in distilled water by intraperitoneal (i.p) injection for 2 months. Group III received the same dose of potassium dichromate with vitamin C (120 mg/kg/day) orally through an intragastric intubation. Group IV received the same dose of potassium dichromate and melatonin (10 mg/kg/day) as an i.p injection. Thyroid gland samples were prepared for light and electron microscopic studies. Potassium dichromate group demonstrated congested blood vessels, follicular hyperplasia, follicular enlargement with degenerated lining cells that were exfoliated in the lumen. The parafollicular cells appeared with darkly stained nuclei. PAS reaction showed weak reaction in the colloid with an abnormal pattern of vacuolization. A highly significant increase in the percentage area of fibrosis was detected in Mallory trichrome sections. Ultrastructurally, follicular cells and parafollicular cells appeared irregular in shape with dark, small heterochromatic nuclei. Small, electron-dense granules in the parafollicular cells were found. Potassium dichromate and vitamin C-treated group III showed partial improvement of the thyroid gland. The PAS reaction showed that nearly all the follicles were more or less similar to those of the control group. A significant decrease in the percentage area of fibrosis in group III was found as compared to those in group II. Potassium dichromate and melatonin-treated group showed that the thyroid gland was nearly similar to that of the control group. Vitamin C and melatonin could partially protect against potassium dichromate induced changes in the thyroid gland and the protective effect of melatonin was better than that of vitamin C.

Abstract
Amiodarone (AMD), an antiarrhythmic drug, is used cautiously due to its lung toxicity that is characterized by alveolar inflammation followed by fatal fibrosis. AMD induces lung inflammation via increasing the alveolar macrophages and disturbing the balance of T-helper-1 (Th1) and Th2 cells cytokines. In this study, the role of the mitogen-activated protein kinases (MAPKs)/activator protein-1 (AP-1) pathway in AMD-induced lung inflammation was evaluated. Also, the anti-inflammatory and antifibrotic effects of losartan and/or vitamin D were investigated following 7, 14, and 28 days of AMD administration. AMD resulted in lung injury, inflammatory infiltration, and increased pulmonary levels of inflammatory cytokines starting from Week 1 of exposure. A significant increase in serum levels of interleukin-4 along with a significant reduction of interferon-gamma, in addition to strong expression of CD68, were reported after 14 and 28 days of AMD administration reflecting Th1/Th2 cytokines imbalance and the accumulation of alveolar macrophages, respectively. The phosphorylation of MAPKs (ERK1/2, JNK, p38) and AP-1 was significantly enhanced starting from Week 1 of exposure. Marked expression of transforming growth factor beta-1 and massive deposition of collagen were detected after 28 days reflecting late fibrosis. All these abnormalities were significantly mitigated by vitamin D and its combination with losartan. Losartan alone has less prominent anti-inflammatory effects particularly after 28 days; however, it efficiently prevented late fibrosis. This study concludes that MAPKs/AP-1 pathway is involved in AMD-induced lung inflammation and that vitamin D and/or losartan could be used as a prophylactic agent to prevent AMD-induced lung toxicity.

Abstract
Mercury (Hg) is one of the most toxic heavy metals and widely utilized in various industries. Hg exposure causes serious health impacts through unfavorable pathological and biochemical effects. We aimed to assess the effect of mercuric chloride (HgCl2) prenatal exposure on the lung development and probable prophylactic effect of vitamin C. The 30 pregnant rats were used in this work and divided randomly into 3 equal groups: Group Ӏ given distilled water, Group ӀӀ given HgCl2 at dose of 4 mg/ BW/day and Group ӀӀӀ given HgCl2 and Vitamin C at dose of 200 mg/kg BW/day. The pups of each group at birth were collected, counted and weighted then lung specimens were extracted, weighted, anaesthetized and processed for the light, electron microscopic and immunohistochemical studies. Also, morphometric studies were performed. We found that prenatal HgCl2 exposure caused collapse of alveoli, thick interalveolar septa, degenerated type Ӏ and type Ӏ pneumocytes, extensive extravasation of RBCs, extensive collagen fibers deposition, positive iNOS immunoreaction and significant decrease in the body and lung weights. Vitamin C concomitant administration partially reversed HgCl2 induced lung degeneration. We concluded that prenatal HgCl2 exposure caused lung damage and vitamin C had protective effects against HgCl2 indued pulmonary toxicity.

Abstract
Bisphenol A (BPA), an imperative environmental contaminant used in polycarbonate plastics. Due to limited information concerning the effect of BPA on lungs, this study design to assess whether BPA cause alterations in histopathology and trace metal content in lungs of rats. They were divided into five groups with five rats per group. Group I was named as control group. Group L6 and L12 were received BPA (10 mg/kg body weight/day) for 6 weeks and 12 weeks respectively. Group H6 and L12 were given BPA (25 mg/kg body weight/day) for 6 weeks and 12 weeks respectively. Considerable alteration in Cu, Zn and Fe was detected in experimental groups. BPA also caused significant increase in the expression of tumor necrosis factor α that mediate the pulmonary inflammatory response. Comparative study of resolved proteins i.e. 72 KDa (matrix metalloproteinase 2 fragment) and 109 KDa (nucleolin) on SDS-PAGE showed their altered expression in experimental groups. Histopathology of experimental groups revealed altered architecture of lungs. Special staining of BPA treated groups showed significant number of mast cells in alveoli and bronchioles. Prolonged administration of BPA causes deleterious aggravating lung damage even at extremely low dose, so the use of BPA should be prohibited in plastic synthesizing industries.

Abstract
Pulmonary fibrosis (PF) is a progressive and irreversible lung disease, characterized by poor prognosis with limited treatment options. Mesenchymal stem cells (MSCs) are multi-potent cells having the ability to self-renew and differentiate into multiple tissues, thus considered a novel treatment option. The present study aimed to investigate the possible antifibrotic effect of undifferentiated adipose tissue-derived mesenchymal stem cell (AD-MSC) therapy on PF experimentally induced in rats using amiodarone (AMD). AMD (30 mg/kg) was given orally, once daily for 12 consecutive weeks to induce lung fibrosis. Following the confirmation of lung damage with histopathological examination, AD-MSCs (2 × 106 and 4 × 106 undifferentiated MSCs) were injected once intravenously, followed by 2 months for treatment. AMD induced focal fibroblastic cells proliferation in the peribronchiolar tissue, as well as in between the collapsed emphysematous alveoli. Also, AMD significantly increased serum and lung homogenate fibroblast growth factor-7 (FGF7), Clara cell protein-16 (CC16), and cytokeratin -19 (CK19) levels, as well as the expression of both iNOS and NFкB in the lung alveoli. Moreover, AMD caused excessive collagen deposition and increased alpha smooth muscle actin (α-SMA) expression. All findings significantly regressed on stem cell therapy in both doses, with superior effect of the high dose, providing evidence that adipose tissue-derived MSCs could be a promising approach for the treatment of PF.

Abstract
OBJECTIVE In this study, we investigated the potential of thiolated chitosan-based mucoadhesive film, loaded with risedronate sodium in the treatment of osteoporosis. SIGNIFICANCE Risedronate sodium is a bisphosphonate derivative having very low bioavailability when administered through the oral route. Moreover, the adverse effects associated with the drug when administered through GIT necessitate an alternative and feasible route which can improve its bioavailability and therapeutic efficacy. METHODS Thiolation of chitosan was interpreted by different analytical techniques. The mucoadhesive films were prepared by the solvent evaporation method and evaluated for drug content analysis, swelling degree, mucoadhesive parameters, and permeation characterization. For the screening of preclinical efficacy and pharmacodynamic parameters, a methylprednisolone induced osteoporotic rat model was used. The trabecular microarchitecture and biochemical markers were evaluated for determination of bone resorption. RESULTS The different analytical characterization of synthesized thiolated chitosan revealed that chitosan was successfully incorporated with thiol groups. The formulation containing 2:1 ratio of thiolated chitosan and HPMC-4KM was found to have the maximum swelling degree, mucoadhesive strength with a good force of adhesion and better in vitro permeability compared to the marketed formulation. With respect to trabecular microarchitecture, the drug-loaded film formulation showed superior and promising results. Furthermore, the film formulation also improved the serum level of biomarkers better than the marketed formulation. CONCLUSIONS The results significantly suggest that risedronate loaded novel mucoadhesive film formulation could be a logical approach in the therapeutic intervention of osteoporosis.

Abstract
RATIONALE Amiodarone is reported to cause hepato and pulmonary toxicity in humans, which has been envisaged to be due to formation of its reactive metabolites, essentially based on its structural similarity to benzbromarone, a drug withdrawn from the market due to reasons of similar hepatotoxicity. Therefore, the purpose of this study was to detect glutathione conjugates of amiodarone and its reactive diquinone metabolites in rat bile using mass spectrometry tools. METHODS Wistar rats were dosed orally with an amiodarone suspension and bile was collected via bile duct cannulation followed by solid-phase extraction, protein precipitation and centrifugation. Samples were analysed by liquid chromatography coupled with linear ion trap mass spectrometry using tandem mass and constant neutral loss scan in positive electrospray ionization mode. RESULTS Glutathione adducts of amiodarone and its reactive diquinone metabolites were identified and characterized with the characteristic neutral loss of 129 Da. Glucuronide conjugates of previously reported stable phase-1 metabolites were also observed. CONCLUSIONS This study confirmed generation of reactive metabolites of amiodarone for the first time, as was hypothesised earlier by various research groups. Also, the responsible toxicophore was identified to be a benzofuran moiety liable to form reactive diquinone species. However, the results need to be further confirmed in human subjects.

Abstract
RATIONALE Several mechanisms have been anticipated for the toxicity of amiodarone, such as oxidative stress, lipid peroxidation, phospholipidosis, free radical generation, etc. Amiodarone is structurally similar to benzbromarone, an uricosuric agent, which was withdrawn from European markets due to its idiosyncratic hepatotoxicity. A proposed reason behind the toxicity of benzbromarone was the production of a reactive ortho-diquinone metabolite, which was found to form adducts with glutathione. Therefore, taking a clue that a similar diquinone metabolite of amiodarone may be the reason for its hepatotoxicity, metabolite identification studies were carried out on the drug using liquid chromatography/mass spectrometry (LC/MS) tools. METHODS The studies involved in vitro (rat liver microsomes, rat liver S9 fraction, human liver S9 fraction) and in vivo (rat feces, urine, plasma) models, wherein the samples were analyzed by employing LC/HRMS, LC/MS(n) and HDE-MS. RESULTS AND CONCLUSIONS A total of 26 metabolites of amiodarone were detected in the investigated in vitro and in vivo matrices. The suspected ortho-diquinone metabolite was one of them. The formation of the same might be an added reason for the hepatotoxicity shown by the drug.
