  • Tetracycline lyogel ointment consisting of hydroxy ethyl cellulose(HEC) in glycerin and Eudragit RS 100 in triacetin were prepared and then release characteristic were investigated. The physical properties of lyogel ointment such as viscosity, particle size and microscopic structures were also evaluated. The microscopic structures showed that lyogel particles containing drug were dispersed in the triactin solution. The release rate of drug from lyogel ointment as a function of HEC was not changed. However the release rate was significantly decresed when the amount of Eudragit RS 100 and triacetin in lyogel ointment was increased. The viscosity and weight fraction in external phase of lyogel ointment influenced the release rate. The current studies suggest that the release rate of drug can be controlled by changing of lyogel ointment compositions.

  • The bark of Alnus japonica has been used for the treatment of fever, hemorrhage and diarrehea in oriental traditional medicine. Recently, it was revealed that the diarylheptanoids from the bark of Alnus japonica possess anti-inflammatory activity and are expected to be applicable for atopic dermatitis. In this study, oregonin, one of major active components in the bark of Alnus japonica, was developed in the form of semisolid formulations for topical delivery. Oregonin was incorporated into four ointment bases: O/W cream, W/O cream, hydrophilic ointment and lipophilic ointment. Oregonin release from all formulation prepared was evaluated. Franz cell method and immersion method were employed to characterize the release patterns of drug from each formulation based on solvent availability. O/W cream showed a better release profile than the other formulations when evaluated with Franz cell method with an order of O/W cream, hydrophilic ointment, W/O cream and lipophilic ointment. In the immersion method, hydrophilic ointment showed the greatest release rate at times 1 hour exceeding compared to other bases with an order of hydrophilic ointment, O/W cream, W/O cream and lipophilic ointment. Hydrophilicity and solvent availability of formulation seems to significantly influence the release rate of oregonin from ointment bases. In this study, we successfully characterized the oregon in ointment and found that o/w cream is a promising formulation for the topical delivery of oregonin.

  • Objectives : Taglisodog-eum(TSE), a poly herbal formula, has been widely used to improve carbuncles by removing inflammation of the lymphatic channels in Traditional Korean Medicine. We previousely reported the action mechanism of TSE on experimental atopic dermatitis and the establishment of formulation for TSE ointment. In this study, we examined the toxicity test on skin and eye irritation by TSE ointment to prove the safety of Taglisodog-eum ointment in clinical use. Methods : Acute skin toxicity of the TSE ointment was evaluated in Sprague-Dawley(SD) rats. After dermal administration of TSE ointment(2,000mg/kg), body weight, mortality, and clinical signs of the rats were observed for 14days. Primary skin irritation and ocular irritation tests for TSE ointment were performed in male New Zealand White Rabbits. In dermal and ocular irritation test, body weight, mortality, clinical signs, Primary Irritation Index(P.I.I.), and The Index of Acute Ocular Irritaion(I.A.O.I.) of rabbit were observed after applying at abraded skin and eye balls with Taglisodog-eum ointment. Results : In the results of acute skin toxicity, no significant differences were found in body weight, the clinical sign and the mortality between control and TSE ointment treated group. In primary dermal irritation test, body weight, the clinical sign and the mortality were not significantly changed and Primary Irritation Index(P.I.I.) was 0.8, indicating TSE ointment as weak irritant material. In ocular irritation test, The Index of Acute Ocular Irritaion was 0.0, indicating TSE ointment as non-irritating to the eye of the rabbits. To evaluate toxicity of the TSE ointment in animal test, body weight, the clinical signs, the skin and eye irritation check were conducted; TSE ointment was considered to be weak dermal irritant in test animals. The no response of eye irritation test was observed in this experimental condition. Conclusions : According to the above toxicity test, We consider that this results is helpful for saying about the safety of TSE ointment in clinical use.

  • Background Skin flap necrosis is a common complication after mastectomy and breast reconstruction. It has been proven that nitroglycerin ointment, as a topical vasodilator, can decrease the rate of skin flap necrosis after mastectomy and breast reconstruction. However, nitroglycerin can cause several side effects, including headache, dizziness, and hypotension. The purpose of this study was to evaluate whether the application of a low dose of nitroglycerin ointment reduced the rate of skin flap necrosis in breast reconstruction after skin-sparing or nipple-sparing mastectomy. Methods A total of 73 cases of breast reconstruction after nipple-sparing and skin-sparing mastectomy at our institution from March 2012 to January 2017 were retrospectively studied. Of these patients, 52 received nitroglycerin ointment (4.5 mg) application to the skin around the nipple-areolar complex from August 2015 to January 2017, while 21 received fusidic acid ointment from March 2012 to August 2015. The number of patients who experienced necrosis of the breast skin flap was counted in both groups. Results Skin flap necrosis developed in 2 (3.8%) patients who were treated with nitroglycerin ointment and 5 (23.8%) patients who did not receive nitroglycerin ointment treatment. Patients who did not receive nitroglycerin ointment treatment had a significantly higher risk of mastectomy skin flap necrosis than patients who did (odds ratio=7.81; 95% confidence interval, 1.38 to 44.23; P=0.02). Conclusions Low-dose nitroglycerin ointment administration significantly decreased the rate of skin flap necrosis in patients who underwent breast reconstruction after skin-sparing or nipple-sparing mastectomy, without increasing the incidence of the side effects of nitroglycerin.

  • Objectives : There have been few studies on external treatment for itching. A clinical study was performed to evaluate the effect of a newly developed herbal ointment. Methods : A newly developed herbal ointment made from Rumex japonicus Houtt, Prunus persica(Linne) Batsch, Sesamum indicum L., and Sus scrota domestics Brisson., was given to 49 participants with itching to administer for approximately a month. Demographic characteristics, treatment experiences, symptom change, and other comments were self-reported on a pre-defined questionnaire. Results : Most frequent complaint was itching (24.01%), followed by sensitivity (19.60%), dryness(18.62%), frustration (13.72%) and insomnia (12.25%). Of 41 participants who had been given treatment for itching, around a half of them (n=21) have been treated with Korean Medicine, but all of them tried Western Medicine as well. The effect of the ointment was evaluated as excellent or good/fair (67.32%). Continuity was reported as excellent or good/fair (51.0%) and fragrance (73.44%) and color (75.48%) was reported as excellent or good/fair. Convenience, however, was assessed as good/fair (67.32%) and as inconvenient (22.4%). Conclusion : The newly developed herbal ointment seems promising for relieving itching and further research to standardize and develop this kind of ointment is warranted.

  • The high prevalence of pediculosis capitis, commonly known as head lice (Pediculus humanus capitis) infestation, has led to the preparation of a community-based pediculicidal ointment, which is made of common household items and the extract of Tinospora crispa stem. The present study aimed to evaluate the safety, efficacy, and physicochemical characteristics of the T. crispa pediculicidal ointment. The physicochemical properties of the ointment were characterized, and safety was determined using acute dermal irritation test (OECD 404), while the efficacy was assessed using an in vitro pediculicidal assay. Furthermore, the chemical compounds present in T. crispa were identified using liquid-liquid extraction followed by ultra-performance liquid chromatography quadruple time-of-flight mass spectrometric (UPLC-qTOF/MS) analysis. The community-based ointment formulation was light yellow in color, homogeneous, smooth, with distinct aromatic odor and pH of $6.92{\pm}0.09$. It has spreadability value of $15.04{\pm}0.98g{\cdot}cm/sec$ and has thixotropic behavior. It was also found to be non-irritant, with a primary irritation index value of 0.15. Moreover, it was comparable to the pediculicidal activity of the positive control $Kwell^{(R)}$, a commercially available 1% permethrin shampoo (P>0.05), and was significantly different to the activity of the negative control ointment, a mixture of palm oil and candle wax (P<0.05). These findings suggested that the community-based T. crispa pediculicidal ointment is safe and effective, having acceptable physicochemical characteristics. Its activity can be attributed to the presence of compounds moupinamide and physalin I.
