OBJECTIVE
To study the induced change of tumor necrosis factor alpha (TNF-alpha) level in serum and colon tissue of guinea pig model with melanosis coli and its significance induced by rhubarb (RB).
METHODS
One hundred and twelve guinea pigs of clean grade were randomly divided into four groups: the
Pathogenic molecular variants in the ADAR gene are a known cause of rare diseases, autosomal recessive Aicardi- Goutières syndrome type 6, severe infantile encephalopathy with intracranial calcifications and dominant dyschromatosis symmetrica hereditaria, demonstrated mainly in Asian adults.
This paper reports on clinical, laboratory, and pathologic findings of 10 cases of an idiopathic form of hyperpigmentation of the clavicular zone, a peculiar entity of circumscribed, glistening, pigmented lesions affecting young Latin women. Pathologic findings consisted of focal to extensive
OBJECTIVE
To explore the significance of colonic epithelial cell apoptosis and tumor necrosis factor α (TNF-α) changing in pathogenesis of melanosis coli (MC) in guinea pig and the molecular mechanism of rhubarb (Rhu) in inducing the disease, by means of using different dosages of Rhu to induce the
A case of peritoneal "melanosis" due to a ruptured left ovarian dermoid cyst is described. Histology showed that the dermoid contained gastric mucosa associated with ulceration, necrosis, and hemorrhage. The areas of pigmentation within the dermoid, omentum, and peritoneal cavity were due to
OBJECTIVE
To describe the MR findings of neurocutaneous melanosis in the brain and correlate these with the known pathology and proposed embryologic basis of this disorder.
METHODS
The brain (seven patients) and spine (three patients) MR scans of seven patients with neurocutaneous melanosis were
The pathogenesis of melasma, a common, photo-induced hyperpigmentary disorder, is not clearly understood. Significant factors linked to melasma are ultraviolet radiation exposure and genetic predisposition. Histological analysis has demonstrated that melasma is caused by a network of cellular
The picosecond lasers have shown to effectively treat tattoo pigments that are intractable to previous multiple Q-switched (QS) laser treatments. Therefore we hypothesized that a picosecond laser would show better efficacy with minimal adverse events in the treatment of melasma and post-inflammatory
