“…There were 1–2 lymph nodes on each side, approximately 2–4 mm in size. The superficial lymph nodes of the head and neck are commonly used as donor sites to treat lymphedema due to their large numbers and subcutaneous location [ 16 , 17 , 18 ]. (5) Axillary lymph node: This is a group of larger lymph nodes.…”

The immune response plays a key role in the disease development of the organism, while immune function serves as an important indicator for animal models evaluation.The tree shrew (Tupaia belangeri chinensis), as a new laboratory animal with a close genetic relationship with primates, has been used to construct various disease models.However, the immune system of tree shrews, especially anatomical descriptions of lymph nodes, is still relatively unknown. In this study, a total of 16 different lymph nodes were identified, including superficial lymph nodes and deep lymph nodes. Superficial lymph nodes were located in the head and neck region (submandibular lymph node, parotid lymph node, deep and superficial cervical lymph nodes) and at the forelimb (axillary and accessory axillary lymph nodes, subscapular lymph node) and hindlimb (popliteal, sciatic, and inguinal lymph nodes). Deep lymph nodes comprise mediastinal lymph nodes located in thoracic cavity and abdominal lymph nodes that are mainly located in each mesentery (mesenteric, gastric, pancreatic-duodenal, renal lymph nodes) or along the major vessels (iliac lymph nodes). In addition, we described the spleen and thymus of the tree shrew, as well as two lymphoid tissues in the top wall of the nasal cavity and the oropharynx. This study mainly describes the tree shrew immune system from an anatomical and histopathological perspective and provides fundamental research references for the establishment of various animal models of tree shrews.

Anatomical education in Thailand has advanced significantly since the first class at Siriraj Medical School in 1890. Gross anatomy was formerly taught by traditional lectures and demonstrations using human anatomical models until cadaveric dissection was officially integrated into the medical curriculum in 1906. Educational standard at the medical school was then raised to an international level during the reform of the medical curriculum with the cooperation of the Rockefeller Foundation in 1923-1935, with the main anatomical disciplines organized into correlated courses, and it has since been continuously improved to the present day. This review summarizes a brief history of anatomical education in Thailand based on experiences at Siriraj Medical School, together with detailing the most significant developments that have occurred over time. Advancements in cadaver preservation and modern educational materials for anatomy teaching are also covered. The primary goal of all advances in anatomical education is to provide students with positive learning experiences that will also improve their learning outcomes.

“…The lateral sides of the hair root are surrounded by the inner and outer root sheath cells [4]. The underside of the hair root is bulb-shaped, and the hair root is in contact with the papilla cells of the dermis, which are surrounded by matrix cells (keratinocytes) [5,6]. The capillaries in the subcutaneous tissue beneath the papilla provide the nutrients, oxygen, and growth factors necessary for hair growth.…”

This narrative review aims to examine the therapeutic potential and mechanism of action of plant extracts in preventing and treating alopecia (baldness). We searched and selected research papers on plant extracts related to hair loss, hair growth, or hair regrowth, and comprehensively compared the therapeutic efficacies, phytochemical components, and modulatory targets of plant extracts. These studies showed that various plant extracts increased the survival and proliferation of dermal papilla cells in vitro, enhanced cell proliferation and hair growth in hair follicles ex vivo, and promoted hair growth or regrowth in animal models in vivo. The hair growth-promoting efficacy of several plant extracts was verified in clinical trials. Some phenolic compounds, terpenes and terpenoids, sulfur-containing compounds, and fatty acids were identified as active compounds contained in plant extracts. The pharmacological effects of plant extracts and their active compounds were associated with the promotion of cell survival, cell proliferation, or cell cycle progression, and the upregulation of several growth factors, such as IGF-1, VEGF, HGF, and KGF (FGF-7), leading to the induction and extension of the anagen phase in the hair cycle. Those effects were also associated with the alleviation of oxidative stress, inflammatory response, cellular senescence, or apoptosis, and the downregulation of male hormones and their receptors, preventing the entry into the telogen phase in the hair cycle. Several active plant extracts and phytochemicals stimulated the signaling pathways mediated by protein kinase B (PKB, also called AKT), extracellular signal-regulated kinases (ERK), Wingless and Int-1 (WNT), or sonic hedgehog (SHH), while suppressing other cell signaling pathways mediated by transforming growth factor (TGF)-β or bone morphogenetic protein (BMP). Thus, well-selected plant extracts and their active compounds can have beneficial effects on hair health. It is proposed that the discovery of phytochemicals targeting the aforementioned cellular events and cell signaling pathways will facilitate the development of new targeted therapies for alopecia.
