The relationship between temperature and apparent logarithmic hardness of ointments were clearly demonstrated. The followings were obtained as the results: 1. When the ointment base was mixed with additives and heated or cooled at various temperatures, the apparent logarithmic hardness in the first trend before reaching the critical point is subject to change mainly by the contents of the additive while in the secondary trend after reaching the critical point is subject to change mainly by the temperature. 2. No Change in the critical point was observed at different temperatures. It is assumed that the crittical point of such ointment bases has no relationship with temperatures and that the critical point itself should rather depend on the physicochemical properties of the additives.

Glycolic acid(GA) is well known the most effective cosmetic ingredient on the epidermal remodeling, accelerated desquamation and inhibitory effect on melanin synthesis. The various cosmetic formulations containing GA have not been reported in terms of stability. This study was to investigate the stability of three formulations(gel, cream, and ointment). The stability of obtained formulations was tested chemical and physical characteristics including the composition stability, hot-cool cycling, the variation of pH and viscosity, and the observation of color and odor. The experimental results showed that the gel and cream containing 5% GA, both formulations have proper stability in the centrifugal test, hot-cool cycling test, viscosity, pH stability and the observation of color and odor. On the other hand, the 5% GA ointment did not have stability. We concluded that the formulations of gel and cream are more suitable than ointment to use GA ingredient for developing cosmetic in terms of stability.

This study was performed to investigate the effects in inflammatory and pain status on rheumatoid arthritis(RA) induced rats by swimming exercise and Achyranthes Radix(AR) extracts ointment according to the application methods with the change of motor-behavioral and histochemistry study through the change of safranin o-fast green stain in the knee joint and prostaglandin $E_2(PGE_2)$ concentration production in serum for 28 days. They were randomly divided into four groups; Group I: RA induction, Group II: application of only swimming exercise after RA induction, Group III: application of only AR extracts ointment after RA induction, Group IV: application of both AR extracts ointment and swimming exercise after RA induction. The following results were obtained. Volume change of hind paw edema and arthritis indices test and arthritic dorsal flexion & plantar flexion pain test, group II, III, IV were showed that significantly decrease to each scores compared with group I (p<.01). Safranin o-fast green stain were showed histological indices, group II, III, IV were showed that significantly decrease the scores of cellular infiltration and synovial hyperplasia(p<.05), pannus formation and cartilage destruction(p<.01) compared with group I. Group IV were the most decreased compared with group II, III. The $PGE_2$ concentration of the group II, III, IV were decreased compared to the group I (p<.01) In conclusion, swimming exercise and AR extracts ointment acts were the most therapeutic intervention in inflammatory and pain control of RA induced rats.

Objectives : The present study was conducted to determine whether Jerksukji-san and Tangnisodok-eum have an effect on treatment of burn. Methods : 24 male rats were randomly divided into 4 groups. Burns were created by scalding on the skin surface. Immediately after being burned, the rats of group 1 were applied with silver sulfadiazine ointment topically on the burn wound. The rats of group 2 were applied with Jerksukji-san ointment topically and administrated Tangnisodok-eum orally. The rats of group 3 were applied with Jerksukji-san ointment topically. The rats of group 4 were cleaned with saline solution. All treatments were applied twice a day. After 3 and 7 days the inflammatory cellularinfiltration and epidermal gap were measured. Data were analyzed by one-way ANOVA and Kruskal-Wallis test. Results : The rats of groups 1 and 2 showed a statistically narrow epithelial gap compared with those of groups 3 and 4 on the third and on seventh days (p<0.05). Group 3 showed a statistically narrow epithelial gap compared with group 4 on the third and seventh days (p<0.05). The decrease of inflammatory cellularinfiltration observed in group 2 was bigger than in the other groups (group 2>1>3>4) on the third and seventh days. Conclusions : These results demonstrate that Tangnisodok-eum and Jerksukji-san ointment are effective to treat burn, and it is necessary for clinical study to better ascertain this method.

Judging from hydrocortisone concentration in dosing area, the extent of absorption was reduced in the liposome-gel formulation. However, higher and sustained skin concentrations of hydrocortisone were achieved for the liposome-gel as compared to the ointment. Drug concentration in both viable and deep skin reached its maximum within 0.5 h after application of both formulations to both skin types. Drug concentrations in both skins from the ointment declined with time, while those from the liposome-gel were greatly sustained. The sustainment by the liposome-gel was more remarkable in the viable skin than in the deep skin. Drug concentration in the viable skin could be maintained at a nearly constant level for over 8 h by applying the liposome-gel. As a result, a 5-fold higher viable skin drug concentration was obtained from the liposome-gel than from the ointment at 8 h after the application to the SC-removed skin. However, the plasma concentration of hydrocortisone at 4 h from the liposome-gel was only one-fourth (p<0.01) the value from the ointment when the drug was applied to the SC-removed skin, consistent with. the lower urinary (one-third, p<0.05) and fecal (one-half, p＜0.05) excretion. Conclusions : Retarded diffusion of the drug from the skin to the systemic blood stream appears to be a potential factor in the sustained skin concentration of hydrocortisone from the liposome-gel, Interaction of hydrocortisone in the skin with phosphatidylcholine, a component of the liposomes and skin, may well be a factor in retarding the diffusion of the drug in the skin.

Gastrodia elata Blume is a well-known kind of natural products used as a folk medicine for thousands of years. However, anti-atopic dermatitis-like effects of G. elata Blume had not been evaluated until now. The aim of the present study is to investigate the protective effects of water extract from the roots of G. elata Blume (GE) on 2, 4-dinitrochlorobenzene-induced atopic dermatitis-like skin lesions using balb/c mice. Combination treatment of GE (at a dose of 12.5 mg/kg body weight by administrated per os + 0.5 mg/cm² as ointment to apply on ear and dorsal skin) was significantly inhibited spleen weight, ear thickness, levels of serum immunoglobulin E and number of mast cells, compared with that of 2, 4-dinitrochlorobenzene-included groups without GE. Furthermore, combination application by oral administration plus by ointment of GE significantly inhibited the histamine release from rat peritoneal mast cells. These results suggest that combination treatment of oral administration plus ointment form of GE could be helpful as a potentially natural pharmaceutical treatment on atopic-like dermatitis.

An 8-year-old, castrated male Shih-tzu was referred due to relapsing pododermatitis and generalized pruritus. On physical examination, right forepaw showed swelling and serosanguinous exudates from sinus tract on dorsal paw. There were no remarkable findings on complete blood count (CBC), serum chemistry, and radiologic examination. On cytological examination of exudates from sinus tract, phagocyted bacteria and numerous degenerative neutrophils were noted. Results of deep skin scraping and plucking hair examination were unremarkable. Skin biopsy was performed and ruled out other skin diseases. Histopathology showed epidermal hyperplasia and diffuse mononuclear cell inflammation in dermal layer. Moreover, pyogranulomatous inflammation was demonstrated in subcutaneous layer. This case was clinically diagnosed as pododermatitis secondary to atopic dermatitis (AD). Clinical signs of pododermatitis were gradually improved following topical application of tacrolimus 0.1% ointment. This case report describes that tacrolimus ointment can be applicable for the treatment of refractory pododermatitis.

The relationship between powders and apparent logarithmic hardness of ointments were clearly demonstrated. The followings were obtained as the results. 1. Apparent logarithmic hardness of ointment were affected by the powders such as zinc oxide, salicylic acid, soluble starch. and talc. 2. The ointments which are added powder have different two slops, $k_1\;and\;k_2$. 3. The slopes, $k_1\;and\;k_2$ were directly correlated and the critical points, were proportional to $k_1\;and\;k_2$ values. 4. The slope, ka is at least $6{\sim}91$ times more sensitive, than the slope, $k_1$, and 25 times more sensitive in average. It was suggested from the results that the quantity of powers which is added to the ointment must be within the critical point.

Objectives : The purpose of this paper is to report the effect of Korean medicine treatments on allergic contact dermatitis aggravated after applying steroid ointment. Methods : We treated a 63-year-old woman with allergic contact dermatitis on the both forearm, jaw, neck, chest with Korean medicine. Before Korean medicine treatments she has taken oral steroids and applied steroid ointment for several years to treat dermatitis, but long-tern steroid therapy aggravated her symptoms like skin pruritus, erythema, exudates or edema. After Korean medical treatment for 27 days, we found that the size of erythema was reduced, and symptoms like pruritus, exudates and edema were lost. We recorded pictures of changes on symptoms. Results & Conclusions : The symptoms of allergic contact dermatitis were improved. Erythema, edema, exudate were lost. Thus Korean medicine treatments are effective on allergic contact dermatitis and could be a great alternative to steroid treatment.
