Abstract
Skeletal muscle (SkM) is a plastic and dynamic tissue, essential in energy metabolism. Growing evidence suggests a close relationship between intramuscular fat accumulation, oxidative stress (OS), extracellular matrix (ECM) remodeling, and metabolic deregulation in SkM. Nowadays natural products emerge as promising alternatives for the treatment of metabolic disorders. We have previously shown that chia seed administration reverts SkM lipotoxicity and whole-body insulin resistant (IR) in sucrose-rich diet (SRD) fed rats. The purpose of the present study was to assess the involvement of OS and fibrosis in SkM metabolic impairment of insulin-resistant rats fed a long-term SRD and the effects of chia seed upon these mechanisms as therapeutic strategy. Results showed that insulin-resistant SRD-fed rats exhibited sarcopenia, increase in lipid peroxidation, altered redox state, and ECM remodeling-increased collagen deposition and lower activity of the metalloproteinase 2 (MMP-2) in SkM. Chia seed increased ferric ion reducing antioxidant power and glutathione reduced form levels, and the activities of glutathione peroxidase and glutathione reductase enzymes. Moreover, chia seed reversed fibrosis and restored the MMP-2 activity. This work reveals a participation of the OS and ECM remodeling in the metabolic alterations of SkM in our experimental model. Moreover, current data show novel properties of chia seed with the potential to attenuate SkM OS and fibrosis, hallmark of insulin-resistant muscle.

Abstract
Lumpfish (Cyclopterus lumpus) is an underutilized marine resource that is currently only being exploited for roe. Lumpfish skin was pre-treated with alkali (0.1M NaOH) and acid (0.1M HCl) at a skin to chemical ratio of 1:10 for 24 h at 5 °C to remove non-collagenous proteins and minerals. The pre-treated skin was washed, and gelatine was extracted with 0.1M of acetic acid at three different ratios (1:5, 1:10, and 1:15), time (12,18, and 24 h), and temperature combinations (12, 28, and 24 °C). The highest total extraction yield (>40%) was obtained with combinations of extraction ratios of 1:15 and 1:10 with a longer time (24 h) and higher temperature (18-24 °C). The highest gelatine content was obtained with an extraction period of 24 h and ratio of 1:10 (>80%). SDS-PAGE analysis confirmed the presence of type-I collagen. A rheological evaluation indicated melting and gelling temperatures, gel strength, and viscosity properties comparable to existing cold-water gelatine sources.

Abstract
Purpose Prunus africana is a well-known plant that is used in Ethiopian traditional medicine for the treatment of wounds and other ailments, although there is no scientific evidence to back up the claims of its wound-healing properties. Thus, the objective of this study is to evaluate the wound-healing potential of P. africana bark extract in mice. Methods The bark of the plant was extracted by successive maceration using 80% methanol and then fractionated with aqueous, n-butanol, and chloroform. The crude extract and solvent fractions were formulated as an ointment. Wound healing activity was evaluated using excision and incision wound models. Total phenol, flavonoid, and alkaloid contents of the crude extract, aqueous, and n- butanol fractions of the plant were determined. Results In both models, mice treated with 5% (w/w) and 10% (w/w) crude extract ointment exhibited a significant (p < 0.001) wound healing activity compared with control as evidenced by the increased rate of wound contraction and hydroxyproline content, the reduced epithelialization time, and the higher skin breaking strength. Mice treated with aqueous fraction ointment exhibited a high percentage of wound healing effect among all solvent fractions. The aqueous fraction consisted of higher phenolic (49.71 ± 0.73 mg/g) and flavonoid (39.58 ± 0.27 mg/g) content, while alkaloid (3.89 ± 0.55 mg/g) content was the lowest. Conclusion Prunus africana stem bark extract demonstrated wound healing activity in mice model which supports the acclaimed use by Ethiopian traditional medicine.

Abstract
The focus of the current study was to interrogate the predictive potential of laser-induced autofluorescence (LIAF) by objectively assessing collagen synthesis in burn wound granulation tissues ex vivo. Prior grafting, granulation tissues (20 samples) following burn injury were collected from 17 subjects of age range 18 to 60 years with patient/donor consent and the corresponding autofluorescence spectra were recorded at 325 nm He-Cd laser (≈2 mW) excitations. The resulting endogenous collagen intensity from the above tissue samples was computed by normalizing the nicotinamide adenine dinucleotide levels. In addition, the hydroxyproline content was also estimated biochemically from the same granulation tissues. A comparative assessment of both LIAF and biochemical estimations for endogenous collagen by hydroxyproline resulted in strong positive correlation among them. The above relevant observations suggest that LIAF is equally informative as that of biochemical estimations, in evaluating endogenous collagen content in wound granulation tissues. Thus, it can be concluded that LIAF has the predictive potential, as a noninvasive objective tool to measure the endogenous collagen levels in wound biopsy tissues and provide complementary data conducive for making clinical decisions.

Abstract
Cdc42-interacting protein-4 (CIP4) has been reported to be closely associated with diabetic nephropathy in rat. However, little is known about the correlation between CIP4 and diabetic pulmonary fibrosis (PF) in mice. Here, diabetes was induced by streptozotocin (STZ), and later lung tissue was collected and subjected to hematoxylin and eosin (H & E) staining for morphological examination. The distinct up-regulation of CIP4 was observed in diabetic PF mice. CIP4 silencing increased overall weight and decreased lung weight. Simultaneously, levels of TGF-β1, collagen-1, collagen-3 and hydroxyproline were down-regulated by CIP4 silencing, accompanied by an increase in MMP-9 expression and a decrease in TIMP-1 expression. Down-regulation of CIP4 suppressed EMT by decreasing the expression of vimentin and α-SMA as well as augmenting E-cadherin expression. Mechanistic analysis confirmed that CIP4 silencing inhibited p-GSK-3β and β-catenin expression, indicating that CIP4 down-regulation attenuated the activation of Wnt/GSK-3β/β-catenin signaling. However, β-catenin overexpression ameliorated the inhibitory effect of CIP4 down-regulation on lung tissue damage, fibrosis-related cytokines and EMT. These results suggest that CIP4 silencing can efficiently alleviate STZ-induced PF in mice, perhaps through suppressing Wnt/GSK-3β/β-catenin signaling.

Abstract
PHARMACOLOGICAL RELEVANCE Root of Hemidesmus indicus (L). R. Br., an herbal drug of India is traditionally used to prevent or treat female hormonal disturbance related disorders and assuaging symptoms of menopausal conditions. AIM OF THE STUDY Lack of scientific data for potential use in bone loss, the present study was undertaken to investigate the effects of ethanol extract of Hemidesmus indicus root for osteoporosis in ovariectomised rats. MATERIALS AND METHODS Thirty wistar female rats were randomly divided into five groups. One group was sham operated and other four groups were undergone dorsal ovariectomy (OVX). After four weeks of post-operative recovery, three OVX groups, viz. Group1, Group2 and Group3 were treated for ninety days with standard raloxifene (RLX) 1mg/kg/day, Hemidesmus indicus root extract (HIRE) 100mg/kg/day and HIRE 200mg/kg/day respectively. Sham and OVX control groups were fed with equal 1% vehicle volume. Serum and urine biochemistry (alkaline phosphatase, tartrate resistant acid phosphatase, triglyceride, total cholesterol, calcium, phosphorous and hydroxyproline), weight of body, uterus and vagina, femur parameters, three point bending of tibia and fourth lumbar vertebra compression were examined. Furthermore, bone architecture and uterine hypertrophy were examined by histopathological studies. RESULTS Application of HIRE has increased bone strength and restored bone turnover markers such as alkaline phosphatase, tartrate resistant acid phosphatase and hydroxyproline moreover, improved femur parameters indicated mineralized bones, similar to the results observed with raloxifene treatment. Histopathology studies showed fibrocartilaginous proliferation of trabecular bone and absence of uterine hypertrophy. CONCLUSION The results strongly suggest that HIRE prevents bone loss in OVX induced osteoporosis without estrogen like side effects. It might be a potential remedy like raloxifene for postmenopausal or estrogen deficiency caused osteoporosis.

Abstract
Abrus cantoniensis (Leguminosae sp.) is a traditionally used remedy for treating rheumatism, blood stasis, and internal injuries. In order to reveal a new insight of the utilization of the plant, solvent extraction by ethyl acetate (EA) was performed in order to evaluate the plant extracts' in vivo excision and incision-wound potentials with models. The contents of the EA fraction, wound healing activity, acute oral toxicity, and acute dermal toxicity were studied. As a result, the main chemical constituents of the EA fraction were alkaloids, flavonoids, and steroids. The acute oral toxicity test results and assessment of skin hypoallergenicity showed that the plant extract was safe at LD50 as high as 5000 mg/kg. Both excision and incision model tests results indicated that the EA fraction of A. cantoniensis showed a significant wound healing capacity at a concentration of 5% (v/w) (p < 0.01) as observed by the increased wound contraction, decreased epithelialization time, and increased hydroxyproline content compared to the ones of the controls. The present study showed that the EA fraction of A. cantoniensis possesses potential wound healing activities and provided recent results for the use of A. cantoniensis for wound curing.

Abstract
The present study was aimed to investigate the anti-arthritic effect of triphala and its underlying mechanism on adjuvant-induced rat model. For comparison purpose, non-steroidal anti-inflammatory drug indomethacin was used. Arthritis was induced by intradermal injection of complete Freund's adjuvant (0.1 ml) into the right hind paw of the Wistar albino rats. Triphala (100 mg/kg body weight [bwt]) was administered intraperitoneally (from 11th to 20th day) after the arthritis induction. Arthritis induction increased the levels of reactive oxygen species (LPO and NO), elastase, and mRNA expression of pro-inflammatory cytokines (TNF-α, IL-β, IL-17, IL-6 and MCP-1), inflammatory marker enzymes (iNOS and COX-2), receptor activator of nuclear factor kappa-B ligand (RANKL), and transcription factors (NF-kB p65 and AP-1) in the paw tissues of rats. The levels of bone collagen were found to decrease with increased urinary constituents (hydroxyproline and total glycosaminoglycans) in arthritic rats. In addition, the immunohistochemistry analysis revealed increased expression of NF-kBp65 and COX-2 in the paw tissues of arthritic rats. However, administration of triphala significantly inhibited the biochemical and molecular alterations in adjuvant-induced arthritic rats compared to indomethacin (3 mg/kg bwt) as evidenced by the radiological and histopathological analysis. In conclusion, our results suggest that triphala administration ameliorate bone and cartilage degradation during rheumatoid arthritis.

Abstract
Background Rumex abyssinicus Jacq (Polygonaceae) is widely used in Ethiopia for treatment of wound and other diseases. Although reports are available in the literature on some of the claimed activities, nothing has so far been reported about the wound healing activity of R. abyssinicus. Thus, this work was initiated to investigate the wound healing and anti-inflammatory activities of 80 % methanol extract of the rhizomes of R. abyssinicus in mice. Methods Following extraction of the rhizomes of the plant with 80 % methanol, the extract was formulated as ointment (5 % & 10 % w/w) with simple ointment base B.P. The ointment was then evaluated for wound healing activity using excision and incision wound models. Parameters, including wound contraction, epithelization time and hydroxyproline content were determined using the excision model, whereas tensile strength was measured from the incision model. In parallel, anti-inflammatory activity of the rhizome was evaluated with carrageenan induced hind paw edema model by dissolving the 80 % methanol extract in 1 % carboxyl methyl cellulose and administering orally in various doses (250, 500 and 750 mg/kg). Results Wound treated with 5 % and 10 % (w/w) hydroalcoholic extract ointment exhibited significant wound healing activity in both models, as evidenced by increased wound contraction, shorter epithelization time, higher tissue breaking strength and increased hydroxyproline content. The hydroalcoholic extract also produced dose-related significant reduction (p < 0.05–0.001) of inflammation. Conclusions The results of this study demonstrated that the hydroalcoholic extract of the rhizomes of R. abyssinicus facilitated wound healing at least in part via its anti-inflammatory activity, supporting its traditional claim as a wound healing agent.

Abstract
Background The traditional use of the oleo-gum-resin of Commiphora guidottii Chiov. ex. Guid., which is commonly called scented myrrh, for topical treatment of wound is well documented. The major objective of the present study was to investigate the essential oil and resin obtained from C. guidottii for their potential wound healing properties. Due to their influence on the wound healing process, the anti-inflammatory and antimicrobial activities of scented myrrh have also been investigated. Methods Powdered oleo-gum-resin of C. guidottii was steam-distilled to obtain essential oil, and the resin was extracted from the marc with MeOH and filtered. The TLC fingerprint profile of the resin has been recorded by using silica gel GF254 as stationary phase. The essential oil components were identified and quantified by GC-MS. Ointments prepared from the essential oil (4 % v/w) and the resin (5 % w/w) were used for wound healing activity tests. Toxicity of the formulated ointments was investigated according to Draize skin irritation test. Acute anti-inflammatory effect in mice was evaluated using carrageenan induced mouse hind paw oedema model. Antimicrobial activity tests were carried out using disk diffusion and broth dilution techniques against 21 pathogenic bacterial and 4 fungal strains. Results Ointment formulations of both the oil and resin were found to be non-irritant at the concentrations used and showed significant (p < 0.05-0.001) increase in wound contraction rate, shorter epithelization time and higher skin breaking strength as compared to the negative control. Overall, the antibacterial and antifungal activities of the oil and resin were comparable with the standard antibiotics ciprofloxacin and griseofulvin, respectively. Conclusion The results confirm that scented myrrh possesses genuine wound healing activity supporting the traditional use of the plant.

Abstract
The present study was designed to assess the combined efficacy of morin, a dietary flavanol and non-steroidal anti-inflammatory drug indomethacin against adjuvant-induced arthritis in rats, an experimental model for rheumatoid arthritis. Arthritis was induced by intradermal injection of complete freund's adjuvant (0.1 ml) into the right hind paw of the Wistar albino rats. Morin (30 mg/kg b.wt), indomethacin (3 mg/kg b.wt) and combination of morin and indomethacin were administered intraperitoneally (from 11th to 20th day) after adjuvant injection. We have found that the activities/levels of lysosomal acid hydrolases (acid phosphatase, β-galactosidase, N-acetyl glucosaminidase and cathepsin-D), glycoproteins (hexose and hexosamine), urinary constituents (hydroxyproline and glycosaminoglycans), reactive oxygen species (LPO and NO), elastase, inflammatory mediators (TNF-α, IL-1β, MCP-1, VEGF and PGE2) and paw edema were significantly increased in arthritic rats compared to controls. Whereas, the anti-oxidant status (SOD, CAT, GPx, glutathione, and ceruloplasmin), body weight and bone collagen was found to be decreased. The mRNA expression of pro-inflammatory cytokines (TNF-α, IL-1β, IL-17, IL-6 and MCP-1), inflammatory enzymes (iNOS and COX-2), RANKL, and transcription factors (NF-kB p65 and AP-1) was found upregulated in the ankle joints of arthritic rats in qRT-PCR analysis. In addition, the increased protein expression of NF-kB p65 and COX-2 was also detected by immunohistochemical analysis. On the other hand, the above said imbalances were regulated back effectively to near normal as evidenced by the histopathological and radiological analysis on combined treatment with morin and indomethacin. Our study indicates that the combination therapy was more effective than either single drug alone in suppressing the pathogenesis of RA.

Abstract
The present findings were aimed to develop an effective form of collagen-chitosan film to investigate the wound healing property in Wistar rats. Primarily, the acid-soluble collagen (ASC) isolated, structurally and physicochemically characterized. FT-IR and 1H NMR spectra were confirmed the collagen peptide crosslinks. The molecular weight of ASC subunits was about 86 kDa and 79 kDa, the proline and hydroxyproline content was 13.15% and 7.55%, respectively. In addition, collagen-chitosan films were successfully prepared in a controlled environment and characterized by FT-IR and DSC. In wound healing, the experimental animal model showed the increased wound size reduction in the CChF treated rats (96.25%) when compared to control rats (33.75%) followed by CF treated rats (65%) and ChF (55%). The histological results well supported these findings. It can be concluded that a better and faster epithelization was observed in the CChF group compared to the other groups.

Abstract
Rheumatoid arthritis (RA) is an autoimmune and chronic inflammatory disease that leads to pannus formation followed by severe joint destruction, characterized by synovial hyperplasia, inflammation and angiogenesis. Swertiamarin is a secoiridoid glycoside that is used as an anti-inflammatory compound, mainly found in Enicostema axillare (Lam) A. Raynal, a medicinal plant used in Indian system of traditional medicine. In the present study, the effect of swertiamarin was evlauated in experimental adjuvant arthritis animal model by the estimation of biochemical (paw thickness, lysosomal enzymes, and urinary degradative products) parameters, proinflammatory cytokines and enzymes along with histopathological and radiographic observations. The proteins of phosphorylated NF-κB/IκB and JAK2/STAT3 transcription factors were also quantified from experimental animals as well as LPS induced RAW 264.7 macrophage cells. In in silico analysis, swertiamarin was docked with proinflammatory enzymes to confirm its potential. The administration of swertiamarin (2, 5, 10mg/kg bw) significantly (P⩽0.05) inhibited the levels of paw thickness, lysosomal enzymes and increased the body weight of experimental animals in a dose dependent manner. In molecular analysis, the treatment decreased the release of proinflammatory cytokines (IL1, TNF, IL-6) and proangiogenic enzymes (MMPs, iNOS, PGE2, PPARγ and COX-2); and also significantly (P⩽0.05) increased the levels of antiinflammatory proteins (IL-10, IL-4) when compared to the disease groups. The swertiamarin treatment significantly (P⩽0.05) inhibited the release of NF-κB p65, p-IκBα, p-JAK2 and p-STAT3 signaling proteins levels on both experimental animals and LPS induced cells. Histopathological and radiological analysis evidenced the curative effect of swertiamarin on bone destruction. The docking studies of swertiamarin on proinflammatory enzymes supported the results from the in vivo experiments. Thus the swertiamarin inhibited the development of arthritis by modulating NF-κB/IκB and JAK2/STAT3 signaling. These findings suggested that swertiamarin acted as an anti-rheumatic agent.

Abstract
Drynaria quercifolia (L.) J. Sm., is an ethnomedicinal plant used widely in Tamil Nadu to treat arthritis. The present study was aimed to evaluate the traditional claim of D. quercifolia rhizome water extract in adjuvant induced arthritic animals. Anti-arthritic effect was studied by assessing the levels of lysosomal enzymes, protein bound carbohydrates, urinary degradative collagen and serum cytokines on control and adjuvant induced arthritis. The paw swelling and body weight were also analyzed. The levels of ROS and lysosomal enzymes in neutrophils of control and adjuvant induced animals were also estimated. D. quercifolia rhizome water extract at doses of 100 and 200mg/kg reduced the paw thickness and elevated the mean body weight of arthritic rats. The treatment with extract showed a significant reduction in the levels of plasma and liver lysosomal enzymes as well as protein bound carbohydrates and urinary degradative collagen levels. The treatment reduced the levels of ROS and lysosomal enzymes in neutrophils significantly. The significant reduction in the levels of serum pro-inflammatory cytokines (TNF-α and IL-1β) and the increment in the levels of anti-inflammatory cytokine (IL-10) were also observed by the treatment. The present study supports the traditional claim of using D. quercifolia to treat rheumatism.

Abstract
Root hairs are single cells that develop by tip growth and are specialized in the absorption of nutrients. Their cell walls are composed of polysaccharides and hydroxyproline-rich glycoproteins (HRGPs) that include extensins (EXTs) and arabinogalactan-proteins (AGPs). Proline hydroxylation, an early posttranslational modification of HRGPs that is catalyzed by prolyl 4-hydroxylases (P4Hs), defines the subsequent O-glycosylation sites in EXTs (which are mainly arabinosylated) and AGPs (which are mainly arabinogalactosylated). We explored the biological function of P4Hs, arabinosyltransferases, and EXTs in root hair cell growth. Biochemical inhibition or genetic disruption resulted in the blockage of polarized growth in root hairs and reduced arabinosylation of EXTs. Our results demonstrate that correct O-glycosylation on EXTs is essential for cell-wall self-assembly and, hence, root hair elongation in Arabidopsis thaliana.

Abstract
We report the design and development of an optical fiber probe-based Helium-Neon (He-Ne) low-level laser therapy system for tissue regeneration. Full thickness excision wounds on Swiss albino mice of diameter 15 mm were exposed to various laser doses of 1, 2, 3, 4, 6, 8 and 10 J cm(-2) of the system with appropriate controls, and 2 J cm(-2) showing optimum healing was selected. The treatment schedule for applying the selected laser dose was also standardized by irradiating the wounds at different postwounding times (0, 24 and 48 h). The tissue regeneration potential was evaluated by monitoring the progression of wound contraction and mean wound healing time along with the hydroxyproline and glucosamine estimation on wound ground tissues. The wounds exposed to 2 J cm(-2) immediately after wounding showed considerable contraction on days 5, 9, 12, 14, 16 and 19 of postirradiation compared with the controls and other treatment schedules, showing significant (P < 0.001) decrease in the healing time. A significant increase in hydroxyproline and glucosamine levels was observed for the 2 J cm(-2) irradiation group compared with the controls and other treatment groups. In conclusion, the wounds treated with 2 J cm(-2) immediately after the wounding show better healing compared with the controls.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a kind of chronic inflammatory autoimmune disease. The degradation of extracellular matrix and cartilage pave way in understanding the molecular mechanisms in RA. Degradation of cartilage is a more complex event involving the local release of metallaoproteases and lysosomal enzymes that mediate inflammation in joints and in the synovial fluid in RA. OBJECTIVES In the present study, the efficacy of a Siddha preparation named Kalpaamruthaa (KA) in ameliorating the disease process via markedly reducing the joint destruction was demonstrated in adjuvant induced arthritis rat model. KA consists of Semecarpus anacardium nut milk extract (SA), dried powder of Emblica officinalis fruit and honey. MATERIAL AND METHODS Both SA and KA were administered at dose of 150 mg/kg b.wt. for 14 days after 14 days of adjuvant injection in rats. The activity of lysosomal enzymes, the level of collagen, glycosaminoglycans (GAGs) and its degradative products were analyzed in control and experimental animals. RESULTS AND CONCLUSION The study revealed that KA exhibited a profound reduction (p<0.05) in the activities of lysosomal enzymes and thereby decreasing (p<0.05) the levels of GAGs and its fractions when compared to arthritis rats. The latter was confirmed by Safrannin O staining for GAGs in the interphalangeal joints of control and experimental animals. The effect of KA was found to be improved than SA and this might be due to the combined interactions of phytoconstituents present in KA.

Abstract
The effect of milk extract of Semecarpus anacardium Linn. nut milk extract (SA) was studied to gain some insight into this intriguing disease with reference to collagen metabolism. Arthritis was induced in rats by injecting Freund's complete adjuvant containing 10mg of heat killed mycobacterium tuberculosis in 1 ml paraffin oil (0.1 ml) into the left hind paw of the rat intradermally. After 14 days of induction, SA (150 mg/kg body weight/day) was administered orally by gastric intubations for 14 days. Decreased levels of collagen and glycosaminoglycans (GAGS) components (chondroitin sulphate, heparan sulphate, hyaluronic acid) and increase in the levels of connective tissue degrading lysosomal glycohydrolases such as acid phosphatase, beta-glucuronidase, beta-N-acetyl glucosaminidase and cathepsin-D observed in arthritic animals were reverted back to near normal levels upon treatment with SA. The drug effectively regulated the uriniray markers of collagen metabolism namely hexosamine, hexuronic acid, hydroxyproline and total GAGS. Electron microscopic studies also revealed the protective effect of SA. Hence, it can be suggested that SA very effectively regulate the collagen metabolism that derange during arthritic condition.
