RESUMO
Saffron (<i>Crocus sativus</i> L.) is classified as a beneficial herb in the treatment of “Oketsu,” eliminating blood stagnation. The clinical symptoms of “Oketsu” include feeling cold and arthralgia. The pathological condition of “Oketsu” is considered to be increased blood viscosity and microvascular disorders.However, no useful biomarker has been reported for evaluation of the degree of “Oketsu.” Here, we investigated the clinical effect of saffron on the symptoms of “Oketsu” in patients with autoimmune diseases. At the same time, we measured the plasma levels of platelet factor 4 (PF-4) and beta-thromboglobulin (β-TG) as platelet activation markers. Seventy-one patients (66 women and 5 men, mean age 52.3 ± 16.1) were studied. They were administered saffron (300mg∼900mg) with traditional Kampo medicine. The clinical symptoms of “Oketsu” improved (80.9%, n=38/47) and we measured PF-4 and β-TG in pre-and post-saffron treatment periods. The plasma levels of PF-4 and β-TG significantly decreased after saffron therapy (PF-4 : before 49.6 ± 29.8, after 24.0 ± 19.6ng/ml, β-TG : before 117.5 ± 64.0, after 64.6 ± 47.1ng/ml;paired t-test, p < 0.0001, respectively). These results suggest that saffron is effective in treatment of the symptoms of “Oketsu” in allergy and collagen disease patients. Moreover, PF-4 and β-TG may be useful biomarkers of the degree of “Oketsu.”
RESUMO
Kakkonkokato is a special formula used for the treatment of rosacea-like dermatitis lesions in the nasal region, but very few cases treated with this formulation have been reported so far. Here, we report three patients with refractory facial eruptions of rosacea-like dermatitis treated successfully with kakkonkokato. Case1was a 39-year-old man who presented with a 15-year history of rosacea-like dermatitis lesions in the nasal region. After 3 weeks' treatment with kakkonkokato, a marked improvement of his lesions was seen, with disappearance of the redness of his face. Case 2 was a 56-year-old woman who presented with a prolonged history of itchy eruptions around her mouth and nasal region. After 8 weeks' treatment with kakkonkokato, an almost complete disappearance of her eruptions was observed. Case 3 was a 26-year-old woman who presented with atopic dermatitis and intractable erythema under her nose, which was refractory to treatment with steroid ointments and antiallergic agents. After 2 months' treatment with kakkonkokato, her erythema completely resolved, along with improvement of the systemic lesions of atopic dermatitis. The observations in these three cases suggest that kakkonkokato may be a useful formula for the treatment of not only rosacea-like dermatitis in the nasal region, but also of refractory facial eruptions of other causes.
