An evaluation of the effects of nonselective and cardioselective ��-blockers on wound healing in Sprague Dawley rats

Objectives:

To investigate the effect of a nonselective β-blocker (propranolol) and cardioselective β-blocker (metoprolol) on wound healing in rats using incision and excision wound models and to compare the effect of these drugs on wound healing.

Materials and Methods:

Propranolol and metoprolol were given orally. Sprague Dawley rats of either sex were used. Incision and excision wound models were used to evaluate the wound-healing activity. Effects of metoprolol and propranolol on tensile strength, period of epithelialization, and hydroxyproline content were observed. Histological analysis was done to see collagen deposition and inflammatory infiltrate.

Statistical Analysis Used:

The data was subjected to analysis of variance (ANOVA) followed by Scheffe''s test. P < 0.05 was considered to be statistically significant. Statistical analysis was done using SPSS software version 15.0.

Results:

Administration of propranolol or metoprolol was shown to decrease tensile strength, delay wound contraction and re-epithelialization, increase inflammatory infiltrate, and reduce collagen density and hydroxyproline levels.

Conclusions:

The results suggest that nonselective and cardioselective β-blockers delay wound healing and these effects are mediated by β1-receptors.KEY WORDS: Excision wound model, incision wound model, metoprolol, propranolol     

Evaluation of Wound Healing Potential of Bauhinia purpurea Leaf Extracts in Rats

The present study was carried out to evaluate the effect of methanol and chloroform extracts of Bauhinia purpurea on experimentally induced excision, incision, burn and dead space wound models in Sprague Dawley rats. Formulations of methanol and chloroform extracts of Bauhinia purpurea were prepared in carbopol and simple ointment base at concentrations of 2.5% and 5% and applied to the wounds. In the excision and burn wound models, animals treated with high doses of methanol and chloroform showed significant reduction in time taken for epithelization and wound contraction (50%) compared to control. A significant increase in breaking strength was found in incision wound model with methanol and chloroform extracts compared to their respective bases. In the dead space wound model, methanol and chloroform extract treatment (100 and 500 mg/kg) orally produced a significant increase in the breaking strength, dry tissue weight and hydroxyproline content of the granulation tissue when compared to control. Among the extracts, methanol extract exhibited more activity followed by the chloroform extract. In conclusion, the present study indicated that Bauhinia purpurea leaves exhibited wound healing activity.     

Burn wound healing property of Cocos nucifera: An appraisal

Objectives:

The study was undertaken to evaluate the burn wound healing property of oil of Cocos nucifera and to compare the effect of the combination of oil of Cocos nucifera and silver sulphadiazine with silver sulphadiazine alone.

Materials and Methods:

Partial thickness burn wounds were inflicted upon four groups of six rats each. Group I was assigned as control, Group II received the standard silver sulphadiazine. Group III was given pure oil of Cocos nucifera , and Group IV received the combination of the oil and the standard. The parameters observed were epithelialization period and percentage of wound contraction.

Results:

It was noted that there was significant improvement in burn wound contraction in the group treated with the combination of Cocos nucifera and silver sulphadiazine. The period of epithelialization also decreased significantly in groups III and IV.

Conclusion:

It is concluded that oil of Cocos nucifera is an effective burn wound healing agent.     

Insulin catalyzes the curcumin-induced wound healing: An in vitro model for gingival repair

Objectives:

Human gingival fibroblasts (hGFs) play a major role in the maintenance and repair of gingival connective tissue. The mitogen insulin with IGFs etc. synergizes in facilitating wound repair. Although curcumin (CUR) and insulin regulate apoptosis, their impact as a combination on hGF in wound repair remains unknown. Our study consists of: 1) analysis of insulin-mediated mitogenesis on CUR-treated hGF cells, and 2) development of an in vitro model of wound healing.

Materials and Methods:

Apoptotic rate in CUR-treated hGF cells with and without insulin was observed by AnnexinV/PI staining, nuclear morphological analysis, FACS and DNA fragmentation studies. Using hGF confluent cultures, wounds were mechanically created in vitro and incubated with the ligands for 48 h in 0.2% fetal bovine serum DMEM.

Results:

CUR alone showed dose-dependent (1–50 μM) effects on hGF. Insulin (1 μg/ml) supplementation substantially enhanced cell survival through up-regulation of mitogenesis/anti-apoptotic elements.

Conclusions:

The in vitro model for gingival wound healing establishes that insulin significantly enhanced wound filling faster than CUR-treated hGF cells over 48 h. This reinforces the pivotal role of insulin in supporting CUR-mediated wound repair. The findings have significant bearing in metabolic dysfunctions, e.g. diabetes, atherosclerosis, etc., especially under Indian situations.KEY WORDS: Curcumin, fibroblast, gingival healing, insulin, regeneration     

Formulation and In Vitro evaluation of pH sensitive oil entrapped polymeric blended gellan gum buoyant beads of clarithromycin

Background and the purpose of the study

A gastroretentive pH sensitive system has been a frontier approach to release the drug in controlled manner in stomach and duodenum. The aim of this study was to develop buoyant beads of gellan based, wherein, the oil was entrapped, blended with hydroxypropyl methyl cellulose or carbopol 934 in order to evaluate its potential for targeted sustained delivery of clarithromycin in the gastric region.

Methods

Buoyant beads of gellan was developed by inotropic gelation technique using calcium carbonate as gas forming agent and the drug polymer dispersion was emulsified with mineral oil. The oil was entrapped and blended with hydroxypropyl methyl cellulose or carbopol 934. The developed beads were evaluated in terms of diameter,% floating, encapsulation efficiency, In vitro drug release, In vivo gastric residence efficacy and clarithromycine concentration in the mucosa of the experimental animal model.

Results

The scanning electron microscope photograph indicated that the prepared beads were spherical in shape and buoyancy, encapsulation efficiency and drug content obtained from all batches were satisfactory. Particle size and percentage buoyancy of the gel beads increased by raising the concentration of calcium carbonate. The formulation exhibited sustained release profile and was best fitted in the Peppas model with n<0.45. Subsequent coating of microbeads exhibited zero-order sustained pattern of the drug release up to 8 hrs. Batch B₄ showed comparatively better residence and the drug concentration in the gastric mucosa of the treated animals.

Conclusion

The result provides evidence that the prepared optimized formulation may be used effectively for pH sensitive gastric targeted antibiotic such as clarithromycin.     

Topical vitamin K1 promotes repair of full thickness wound in rat

Objectives:

Application of vitamin K to the skin has been used for suppression of pigmentation and resolution of bruising. However, in rats, no study was reported on its effect regarding wound healing. Thus, the present study was designed to examine the healing effects of creams prepared from vitamin K₁ on full-thickness wound in rats.

Materials and Methods:

For inducing full-thickness wound in rats, the excisional wound model was used. Five groups consisting of 8 rats each were used. Vitamin K cream (1% and 2%, w/w) was prepared in eucerin base and applied on the wound once a day until complete healing had occurred. Healing was defined by decreased wound margin (wound contraction), re-epithelialization, tensile strength and hydroxyproline content. Histopathological examination was also done.

Results:

The effects produced by the topical vitamin K showed significant (P < 0.01) healing when compared with control group in parameters such as wound contraction, epithelialization period, hydroxyproline content and tensile strength. Histopathological studies also showed improvement with vitamin K.

Conclusions:

Topical vitamin K demonstrates wound healing potential in full-thickness wound model.KEY WORDS: Excision, rat, vitamin K₁, wound healing     

Wound healing profile of Septilin

Septilin, a proprietary preparation claimed to be useful in inflammatory conditions was tested for anti-inflammatory and wound healing effects in albino rats. It significantly enhanced gain in tensile strength in incision wounds and wound contraction and epithelization in excision wounds. It also suppressed acute inflammation (rat paw edema) significantly without affecting chronic inflammation (cotton pellet granuloma).     

Wound healing activity of extracts derived from Shorea robusta resin

Context: Shorea robusta Gaertn.f. (Dipterocarpaceae) resin is used for treating infected wounds and burns by tribals in India.

Objectives: The objective of this study was to investigate wound-healing activity of S. robusta resin extracts and essential oil in rats.

Materials and methods: Methanol extract (SRME), petroleum ether, benzene insoluble fraction of methanol extract (SRPEBIME), and essential oil (SREO) of S. robusta resin were incorporated in soft yellow paraffin (10% w/w) and applied once daily on incision and excision wounds of Wistar rats. Framycetin ointment (1.0% w/w) was applied to the standard group. Tensile strength (on the 10th day), wound contraction, and scar area (on the 14th day) were recorded. On the 15th day, granulation tissues of excision wounds were analyzed for total protein, hydroxyproline, and hexosamine contents and activities of lipid peroxidation and super oxide dismutase (SOD). Histopathology of the wounds was also studied.

Results and discussion: SRPEBIME and SREO healed incision and excision wounds faster than plain ointment base and framycetin. Tensile strength of SRPEBIME-treated incision wounds was 53% higher than that of control animals. In excision wounds, wound contraction and scar areas were found to be 99% and 7.7?mm² (SRPEBIME) and 71.7% and 21?mm² (control). Protein and hydroxyproline contents were higher in SRPEBIME (20.8 and 3.5% w/w) and SREO (17.4 and 2.8% w/w) groups as against 9.95 and 1.48% w/w in control groups. Histopathology revealed complete epithelization and new blood vessel formation in SRPEBIME groups.

Discussion and conclusion: SRPEBIME and SREO have significant wound-healing activities on incision and excision wounds.     

Effect of histamine on wound healing.

Using incision, excision and dead space wound models in rats, a study was conducted on the effect of histamine on wound healing. Exogenous histamine given either ip or locally was without any effect. Semicarbazide as (histamine synthesis inhibitor) suppressed healing process (breaking strength of skin incision wound), decreased breaking strength and hydroxyproline content of granulation tissue and delay in period of epithelization. On the other hand compound 48/80 (a promoter of histamine forming capacity) was found to promote wound healing. Exogenous histamine (topical) reversed the anti-healing effect of semicarbazide on incision and excision wounds.     

In vivo bioavailability studies of sumatriptan succinate buccal tablets

Back ground and the purpose of study

Sumatriptan succinate is a Serotonin 5- HT1 receptor agonist, used in treatment of migraine. It is absorbed rapidly but incompletely when given orally and undergoes first-pass metabolism, resulting in a low absolute bioavailability of about 15%. The aim of this work was to design mucoadhesive bilayered buccal tablets of sumatriptan succinate to improve its bioavailability.

Methods

Mucoadhesive polymers carbopol 934 (Carbopol), HPMC K4M, HPMC K15M along with ethyl cellulose as an impermeable backing layer were used for the preparation of mucoadhesive bilayered tablets. In vivo bioavailability studies was also conducted in rabbits for optimized formulation using oral solution of sumatriptan succinate as standard.

Results

Bilayered buccal tablets (BBT) containing the mixture of Carbopol and HPMC K4M in the ratio 1:1 (T1) had the maximum percentage of in vitro drug release within 6 hrs. The optimized formulation (T1) followed non-Fickian release mechanism. The percentage relative bioavailability of sumatriptan succinate from selected bilayered buccal tablets (T1) was found to be 140.78%.

Conclusions

Bilayered buccal tablets of sumatriptan succinate was successfully prepared with improved bioavailability.     

Standardized Clitoria ternatea leaf extract as hyaluronidase, elastase and matrix-metalloproteinase-1 inhibitor

Aim:

Plant Clitoria ternatea L. is claimed to possess a wide range of activities including antiinflammatory, local anesthetic and antidiabetic effect, etc. The aim of the present study was to evaluate the wound healing potential of standardized C. ternatea leaf extract in terms of different enzymatic models, which are mostly associated with skin wound.

Materials and Methods:

The methanol extract and fractions were screened for its hyaluronidase, elastase, and matrix metalloproteinase-1 (MMP-1) inhibitory activity compared with standard oleanolic acid. The activity was rationalized through reverse phase high performance liquid chromatography (RP-HPLC) standardization of the extract and fractions with respect to its isolated biomarker taraxerol (yield 5.27% w/w).

Results:

The extract showed significant (P < 0.001) hyaluronidase (IC₅₀ 18.08 ± 0.46 μg/ ml) and MMP-1 (P < 0.05) inhibition, but the elastase inhibition was insignificant (IC₅₀ 42.68 ± 0.46 μg/ml). Among the fractions, ethyl acetate fraction showed significant (P < 0.001) inhibition of hyaluronidase (IC₅₀ 28.01 ± 0.48 μg/ml) and MMP-1 (P < 0.01). The HPLC analysis revealed that the extract and the ethyl acetate fraction are enriched with taraxerol (5.32% w/w and 4.55% w/w, respectively).

Conclusions:

The experiment validated the traditional uses of C. ternatea and may be recommended for use in the treatment of different types of skin wounds, where taraxerol may be a responsible biomarker.KEY WORDS: Clitoria ternatea, elastase, hyaluronidase, matrix-metalloproteinase-1, taraxerol     

Influence of drug concentration on the diffusion parameters of caffeine

Background and Objectives:

In the fields of the pharmaceutical and cosmetic industries and in toxicology, the study of the skin penetration of molecules is very interesting. Various studies have considered the impact of different physicochemical drug characteristics, skin thickness, and formulations, on the transition from the surface of the skin to the underlying tissues or to the systemic circulation; however, the influence of drug concentration on the permeation flux of molecules has rarely been raised. Our study aims to discover the influence of caffeine concentration in a formulation on the percutaneous penetration from gels, as a result of different dose applications to polysulfate membrane and human skin.

Materials and Methods:

For this purpose, three identical base gels were used at 1, 3, and 5% of caffeine, to evaluate the effect of the concentration of caffeine on in vitro release through the synthetic membrane and ex vivo permeation through the human skin, using diffusion Franz^TM cells.

Results:

The diffusion through the epidermal tissue was significantly slower than through the synthetic membrane, which recorded an increase of flux with an increase in the concentration of caffeine. The skin permeation study showed that diffusion depended not only on the concentration, but also on the deposited amount of gel. Nevertheless, for the same amount of caffeine applied, the flux was more significant from the less concentrated gel.

Conclusion:

Among all the different concentrations of caffeine examined, 1% gel of caffeine applied at 5 mg / cm² showed the highest absorption characteristics across human skin.     

Efficacy of topical phenytoin on chemotherapy-induced oral mucositis; a pilot study

Background and the Purpose of the Study

Oral mucositis is one of the most common complications of malignancy chemotherapy. As yet, no absolute treatment has been demonstrated to be effective for chemotherapy-induced oral mucositis. This study evaluates the effectiveness of phenytoin mouthwash as a wound healing agent, on the basis of stimulating effects on fibroblast proliferation.

Materials and Methods

In this multicenter, randomized, placebo-controlled clinical trial; twelve patients received phenytoin mouthwash (0.5%) or placebo for about two weeks. Oral pain severity was scored on the daily basis using a VAS (visual analogue scale) of 10 centimeters. National Cancer Institute (NCI) scale was used to grade the intensity of mucositis. To determine the effect of treatment, a quality of life questionnaire, consisting of 35 queries, was filled out for all patients. Statistical analyses of data was performed using Mann-Whitney test.

Results

The average time for complete remission of mucositis in phenytoin-treated group was less than that of the placebo group. The quality of life improved dramatically in the phenytoin group with the healing process being more evident in the first week. Furthermore, reduction in the wound area was greater in the phenytoin group than controls at the end of the first week of treatment. Both groups eventually demonstrated reduction in pain intensity; however no statistically significant difference was observed between two groups.

Conclusion

Phenytoin mouthwash accelerated wound healing and resolution of mucositis and improved life quality impressively.     

Comparison of preoperative nepafenac (0.1%) and flurbiprofen (0.03%) eye drops in maintaining mydriasis during small incision cataract surgery in patients with senile cataract: A randomized,double-blind study

Aims:

This study compared the effectiveness of prophylactic administration of topical flurbiprofen 0.03% and nepafenac 0.1% in maintaining mydriasis during small incision cataract surgery (SICS).

Materials and Methods:

This study was a prospective, randomized, double-blind comparative study in adult cataract patients given topical flurbiprofen or nepafenac prior to SICS and capsular bag intraocular lens (IOL) implantation at a tertiary care hospital. Horizontal and vertical diameters of pupil were measured at the beginning and end of surgery, and the mean values were compared across the two groups. Unpaired t-test and Fisher''s exact test were used to analyse the results.

Results:

A total of 70 eyes of cataract surgery patients, 33 males and 37 females, with a mean age of 58.5 ± 11.24 years, were included in the study. The mean horizontal and vertical diameters of the two groups were similar at the start of surgery. Significant differences were seen after IOL implantation, with the nepafenac group having the larger mean diameters in both horizontal (P = 0.03) and vertical (P = 0.04) pupillary measurements.

Conclusions:

Topical nepafenac has been shown to be a more effective inhibitor of meiosis during SICS and provides a more stable mydriatic effect compared to topical flurbiprofen.     

Does terfenadine-induced ventricular tachycardia/fibrillation directly relate to its QT prolongation and Torsades de Pointes?

BACKGROUND AND PURPOSE

Terfenadine has been reported to cause cardiac death. Hence, we investigated its pro-arrhythmic potential in various in vitro models.

EXPERIMENTAL APPROACH

Pro-arrhythmic effects of terfenadine were investigated in rabbit isolated hearts and left ventricular wedge preparations. Also, using whole-cell patch-clamp recording, we examined its effect on the human ether-à-go-go-related gene (hERG) current in HEK293 cells transfected with hERG and on the I_Na current in rabbit ventricular cells and human atrial myocytes.

KEY RESULTS

Terfenadine concentration- and use-dependently inhibited I_Na in rabbit myocytes and in human atrial myocytes and also inhibited the hERG. In both the rabbit left ventricular wedge and heart preparations, terfenadine at 1 µM only slightly prolonged the QT- and JT-intervals but at 10 µM, it caused a marked widening of the QRS complex, cardiac wavelength shortening, incidences of in-excitability and non-TdP-like ventricular tachycardia/fibrillation (VT/VF) without prolongation of the QT/JT-interval. At 10 µM terfenadine elicited a lower incidence of early afterdepolarizations versus non- Torsades de Pointes (TdP)-like VT/VF (100% incidence), and did not induce TdPs. Although the concentration of terfenadine in the tissue-bath was low, it accumulated within the heart tissue.

CONCLUSION AND IMPLICATIONS

Our data suggest that: (i) the induction of non-TdP-like VT/VF, which is caused by slowing of conduction via blockade of I_Na (like Class Ic flecainide), may constitute a more important risk for terfenadine-induced cardiac death; (ii) although terfenadine is a potent hERG blocker, the risk for non-TdP-like VT/VF exceeds the risk for TdPs; and (iii) cardiac wavelength (λ) could serve as a biomarker to predict terfenadine-induced VT/VF.     

Allosteric effects of erythromycin pretreatment on thioridazine block of hERG potassium channels

Background and Purpose

The prevalence of concurrent use of two or more drugs that block human ether-a-go-go-related gene product (hERG) K⁺ channels is not uncommon, but is not well characterized. This study defined the effects of concurrent exposure of two hERG-blocking drugs on hERG current amplitude. Experiments were conducted to determine if concomitant exposure to two potent pore hERG blockers, thioridazine and terfenadine and a weak hERG blocker, erythromycin, would result in an additive, synergistic or inhibitory effect.

Experimental Approach

hERG currents from stably transfected HEK cells were measured using the whole-cell variant of the patch-clamp method at physiological temperatures. Concentration–response relationships for thioridazine or terfenadine were obtained with cells pre-exposed to erythromycin.

Key Results

Pre-exposure of cells to erythromycin resulted in an approximately 14–22-fold rightward shift in the hERG concentration–response curve for thioridazine and terfenadine respectively. This reduction in affinity was not the result of a change in the voltage-dependent characteristics of the channel. Results suggest an external binding site for erythromycin.

Conclusions and Implications

Pretreatment with erythromycin induced an approximately 14–22-fold reduction in hERG affinity for pore-binding drugs at concentrations of erythromycin, which by themselves only block hERG by 10% or less. These results suggest distinct, allosterically linked binding sites on opposite sides of the hERG channel. Occupancy of the external site by erythromycin reduces the affinity of the pore binding site. Furthermore, these results suggest that co-administration of erythromycin may provide some reduction in cardiac liability of potent hERG-blocking drugs.     

Roles of affinity and lipophilicity in the slow kinetics of prostanoid receptor antagonists on isolated smooth muscle preparations

BACKGROUND AND PURPOSE

The highly lipophilic acyl-sulphonamides L-798106 and L-826266 showed surprisingly slow antagonism of the prostanoid EP₃ receptor system in guinea-pig aorta. Roles of affinity and lipophilicity in the onset kinetics of these and other prostanoid ligands were investigated.

EXPERIMENTAL APPROACH

Antagonist selectivity was assessed using a panel of human recombinant prostanoid receptor-fluorimetric imaging plate reader assays. Potencies/affinities and onset half-times of agonists and antagonists were obtained on guinea-pig-isolated aorta and vas deferens. n-Octanol-water partition coefficients were predicted.

KEY RESULTS

L-798106, L-826266 and the less lipophilic congener (DG)-3ap appear to behave as selective, competitive-reversible EP₃ antagonists. For ligands of low to moderate lipophilicity, potency increments for EP₃ and TP (thromboxane-like) agonism on guinea-pig aorta (above pEC₅₀ of 8.0) were associated with progressively longer onset half-times; similar trends were found for TP and histamine H₁ antagonism above a pA₂ limit of 8.0. In contrast, L-798106 (EP₃), L-826266 (EP₃, TP) and the lipophilic H₁ antagonists astemizole and terfenadine exhibited very slow onset rates despite their moderate affinities; (DG)-3ap (EP₃) had a faster onset. Agonism and antagonism on the vas deferens EP₃ system were overall much faster, although trends were similar.

CONCLUSIONS AND IMPLICATIONS

High affinity and high liphophilicity may contribute to the slow onsets of prostanoid ligands in some isolated smooth muscle preparations. Both relationships are explicable by tissue disposition under the limited diffusion model. EP₃ antagonists used as research tools should have moderate lipophilicity. The influence of lipophilicity on the potential clinical use of EP₃ antagonists is discussed.     

Healing potential of Anogeissus latifolia for dermal wounds in rats

Wound healing potential of ethanolic extract of Anogeissus latifolia bark (ALE) for treatment of dermal wounds in rats was studied on excision and incision wound models. HPTLC of the total extract was recorded for the purpose of standardization. Various parameters of incision wound, viz. epithelization period, scar area, tensile strength and hydroxyproline measurements along with wound contraction, were used to evaluate the effect of A. latifolia on wound healing. The results obtained indicate that A. latifolia accelerates the wound healing process by decreasing the surface area of the wound and increasing the tensile strength. Nitrofurazone ointment was used as a positive control. Complete epithelization was observed within 15 days with ALE. Measurements of the healed area and the hydroxyproline level were in agreement. Antibacterial activity of ALE was studied against Gram-positive (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae) compared to erythromycin and tetracycline. Moderate activity was observed against all organisms. The present study provides a scientific rationale for the traditional use of Anogeissus latifolia in the management of skin diseases such as sores, boils and itching.
