This research conducted at Mae Fah Luang University Hospital explores the differential effectiveness of Platelet-Rich Fibrin (PRF) versus Platelet-Rich Plasma (PRP) in managing melasma, a challenging dermatological condition characterized by dark, uneven patches on the face, which can significantly impair the mental well-being and quality of life of sufferers. The study engaged 20 Thai women, aged 30 to 65, all with Fitzpatrick skin types III to VI.
Utilizing a split-face experimental design, each participant received PRP on one side of the face and PRF on the other side over a period of 12 weeks, allowing a controlled and direct comparison of the two treatments on the same individual. The effectiveness of the treatments was meticulously assessed using the Modified Melasma Area and Severity Index (mMASI), alongside Mexameter® measurements, which provided quantitative data on melanin and erythema indices—key parameters in evaluating the progression and treatment response of melasma. The findings revealed a statistically significant reduction in mMASI scores in PRF-treated areas compared to PRP, with PRF also demonstrating a significant decrease in melanin levels. These results suggest a superior efficacy of PRF over PRP for melasma treatment. Patient satisfaction, an integral component of the study, was gauged through a well-structured
questionnaire, revealing high overall contentment with both treatment modalities. Notably, the satisfaction levels were marginally higher for PRF, although not reaching statistical significance. This study underscores the potential of PRF as a more effective alternative to PRP in the treatment of melasma, paving the way for further research into its long-term benefits and broader clinical applications in dermatology.

Tongkat Ali (Eurycoma) is a popular medicinal plant in Thailand. Tongkat Ali herb is in the Eurycoma genus originates from the southern border provinces and Malaysia. The Eurycoma is one of the most important genus, however only few comprehensive research studies have dealt on it and methodogies to propagate this genus are also limited. Here, we study to evaluate the genetic diversity of sixteen Eurycoma sp. simple sequence repeat (SSR) markers from southern and northeastern of Thailand in the 18 pairs of microsatellite markers were examined. Authenticated polymorphisms were detected in a total of ten SSR primer pairs and lead to an array of DNA fragments that differed between three band sizes from each fragment, with requiring 1 at least for two states on either side or not. On average, five alleles were recorded for each marker and PIC values varied from 0.26 to 0.68. The genetic similarity coefficients of all samples ranged from 0.63 to 1. Most samples from Narathiwat and Yala provinces were in the same group (similarity coefficient = 0.66), while samples from Amnat Charoen and Ubon Ratchathani provinces were in another group (similarity coefficient = 0.72). This study provides valuable information for establishing a genetic diversity database and guides future studies on active substances in Eurycoma sp., which may contribute to the development of new herbal medicine formulations.
