Objectives : The purpose of this study is to investigate the possibility of using herbal medicine for the management of psoriasis focusing on lipid metabolism. Methods : We reviewed studies about pathophysiology, and medical treatment of psoriasis, the relationship between psoriasis and metabolic syndrome and lipid metabolism, and herbal medicine on Pubmed and Google scholar. Results : Psoriasis is a chronic multi-organ inflammatory disease not limited to skin, and steroids, immuno-suppressants, and biological agents are used. It is known that psoriasis and metabolic syndrome act as mutual risk factors, and lipid metabolism are involved in psoriasis. The effects of various single herbal preparations and complex herbal extract, decoction on improving lipid metabolism have been consistently reported, and there was an improvement of psoriatic skin lesions and improvement of blood lipid levels through herbal medicine. Conclusions : Herbal medicine research in psoriasis has focused on the anti-inflammatory effect and the suppression effect of certain immune mediators. However, considering that psoriasis is affected by lipid metabolism and side effects of Western medicines, the use of herbal medicines for the purpose of controlling lipid metabolism in psoriasis is useful in aspects of reducing side effects of concurrent Western medicine, improving the severity of psoriasis, and managing metabolic risk factors.

Objective: The goal of this preclinical study was to compare the dyslipidemic effect of pravastatin with that of herbal medicine in rats. Methods: In total, 40 rats were divided into 4 groups: Normal (10 rats), Control (10 rats), Statin alone (10 rats), and the MO-PM-S group (10 rats), which was given the powder of the cortex of Magnolia officinalis Rehd. et Wils., the root of Polygonum multiflorum Thunb, and pravastatin. The Control group, the Statin alone group, and the MO-PM-S group were all given a high-fat (45%) diet that made them obese. After 2 weeks of drug administration, the dyslipidemic effect of pravastatin was compared with that of herbal medicine in rats by analyzing the lipid profiles, measuring the body weights, and taking biopsies (liver, aorta). Results: The herbal medicine and the statin complex group got a much lower TG level and a slightly higher HDL-cholesterol level than the other groups. However, it got a higher total cholesterol and LDL-cholesterol level than the other groups. In biopsies, 30% of the Statin alone group and 10% of the MO-PM-S group showed mild histopathologic findings in the liver. Conclusion: The cortex of the Magnolia officinalis Rehd. et Wils. and the root of Polygonum multiflorum Thunb have dyslipidemic effects from the perspective of a TG level and HDL-cholesterol. However, the herbal mixture has a raising effect on both the LDL-cholesterol and the total cholesterol levels. Therefore, we cannot conclude that the herbal mixture helps to prevent dyslipidemia. In liver biopsies, the group administered with both the herbal mixture and the statin showed less histopathologic findings than the group administered with statin alone. This means that the herbal mixture helps to prevent fatty degeneration of the liver.

Infants with tuberous sclerosis complex (TSC) have a higher chance of experiencing seizures before the age of 1 year; in particular, they commonly accompany infantile spasms. In cases where infantile spasms resulting from TSC are drug-resistant, more severe neuro-developmental and cognitive impairments occur. This particular case dealt with an infant with TSC who continued to experience partial seizures and infantile spasms despite using two different kinds of antiepileptic drugs (AEDs). His spasms ceased on the seventh day of taking modified Yukmijihwang-tang (YMJ), at which point he stopped the use of all AEDs. He became seizure-free after a month of the treatment and modified hypsarrythmia was found to have been resolved in the electroencephalogram test. Until now, the infant has been taking YMJ for 16 months and is maintaining the seizure-free state without side effects. Moreover, his developmental status is continually improving, with a significant progress in language and cognitive-adaptive abilities. Such results suggest that YMJ can serve as an alternative treatment option for refractory epilepsy.

The incidence of canine cognitive dysfunction syndrome (CCDS), a prominent geriatric disease, is increasing because of the extended lifespan of companion animals. Various complementary therapies have been proposed for the management of CCDS. This study evaluated the clinical efficacy of the Brain Six Complex Extract^ⓒ in dogs with cognitive dysfunction syndrome (CDS). Fifteen dogs with CDS were included, and four to five drops of Brain Six Complex Extract^ⓒ, composed of herbal extracts, were applied around the dorsal neck of all dogs twice daily for 1-3 months. Clinical efficacy was evaluated using the CCDS scale, and serum β-amyloid oligomer concentrations were measured before and after administration of the extract. The CCDS scale score significantly decreased after administration in dogs with CDS (p = 0.0313), compared to pre-administration levels. Although the serum β-amyloid oligomer concentration decreased after administration, the change was not statistically significant (p > 0.05). A notable decrease was observed between pre- and post-administration in dogs with β-amyloid levels >300 pg/mL (p = 0.0313). The laboratory results showed no remarkable adverse effects of the extract. This study suggests that Brain Six Complex Extract^ⓒ extract could be an adjunctive treatment for dogs with CDS.

Ginseng root has been used as a tonic remedy in Traditional Chinese Medicine for centuries. Modern studies have demonstrated that ginseng root has complex components and multiple pharmacological properties. The effects of ginseng leaf, however, are not well known. Recent studies show that compared to ginseng root, ginseng leaf and stem exhibit a higher content of active compositions such as ginsenosides, polysaccharides, triterpene flavonoids, volatile oil, polyacetylenic alcohols, peptides, amino acids and fatty acids. Ginseng leaf possesses multiple pharmacological effects in the central nervous, cardiovascular, growth and metabolism systems. Additionally, the leaf has anti-fatigue, anti-hyperglycemic, anti-oxidant, and anti-aged effects. In general, ginseng leaf is quite safe, but adverse effects may occur if it is abused or is of poor quality. Thus, attention must be paid to dosages, quality, and standardization of ginseng leaf products.

Objectives The aim of this study was to analyze the research trends in herbal medicine as a treatment for atopic dermatitis (AD) in an animal model. Methods We conducted a search targeting papers published from 2013 onwards in Korean and English databases. The search terms were focused on "AD", "dermatitis", and "Korean medicine". Only animal experimental studies involving the oral administration of single or complex prescriptions of Korean medicine were included, whereas in vitro studies, local administration studies, and studies of specific components of Korean medicine were excluded. We searched the PubMed and Embase databases for English databases and the Science on Research Information Sharing Service (RISS) and Korean Studies Information Service System (KISS) databases for Korean studies. Results Among the herbal medicine intervention groups, the most commonly used single herbs were baekseonpi, danggui, and douchi, whereas a mixture of hwangryun and gamcho was used in three studies, making it the most frequently used combination. There were significant improvements in indicators related to the symptoms of AD and various pro-inflammatory markers. Conclusions These results indicate the efficacy of herbal medicines in the treatment of AD in animal models. However, this study had several limitations. Therefore, future systematic reviews that address these limitations and provide more comprehensive analyses are required.

The purpose of this study is to examine the effect of herbal medicine complex (HMC) containing Camellia sinensis L., Duchoesna chrysantha, Houttuynia cordata Thunberg, Poncirus trifoliata Rafinesque on skin inflammation and atopic dermatitis. First, we examined the anti-inflammatory effect of HMC in TNF-α induced human keratinocytes (HaCaT cell). Real-time PCR and western blotting were performed to evaluate the expression of inflammatory cytokines (e.g., iNOS, COX-2, IL-6, IL-8) mRNA and protein. Four-weeks old male NC/Nga mice were treated with 1% 2,4-dinitrochlorobenzene (DNCB) solution and used as an atopic dermatitis mice model. And, HMC (200 mg/kg or 400 mg/kg) was administered directly into the stomach of mice for 4 weeks, and blood or serum analysis, tissue staining were performed after oral gavage. As a result HMC inhibited the mRNA expression of iNOS, COX-2, IL-6, and IL-8, which had been increased by TNF-α in HaCaT cells. In addition, the protein expression was also significantly suppressed in the same way as the mRNA expression results. The in vivo experiment results showed that, HMC administration reduced thickening of the epidermis and infiltration of eosinophil into the skin stratum basale compared to DNCB treatment. In addition, HMC administration significantly reduced the inflammatory cytokines (IL-4, IL-5, IL-6, and IL-13) production and immunocyte (white blood cell, lymphocyte, neutrophil, and eosinophil) count compared to DNCB treatment. Moreover, the serum IgE and histamine level was decreased by HMC administration. These results suggest that HMC can be used as effective herbal medicine extract for skin inflammation and atopic dermatitis. And this study may contribute to the development of the herbal medicine-based drug for the treatment of skin inflammation and atopic dermatitis.

The interaction of cadmium (II) ion with quercetin was investigated in aqueous solution at different pH. The quercetin/cadmium stochiometries for cadmium (II) binding have been determined by UV-vis spectrophotometric method. The complexation of Cd(II) ion with 54.72 ${\mu}M$ quercetin (A=1.00793) was formed in 0.2 M $NH_3-0.2$ M $NH_4Cl$ (pH 8.0) buffer solution. 1:1 Cd(II)-complex had a maximum absorbance and showed the bathochromic shift of the long-wavelength band of the UV-vis spectra in the alkaline pH when interacted with quercetin in buffer solution. These results suggest that Cd(II)-quercetin complex has the optimal condition of chelation in basic buffer solution.
