Comparison of wound healing effects between -derived polydeoxyribonucleotide (PDRN) and -derived PDRN.

Background: Polydeoxyribonucleotide (PDRN) influencing cellular growth and differentiation is recognized to promote wound healing by stimulating tissue repair. Although PDRN can be extracted from human placentas, PDRN medications have recently been extracted from the semen of trout () and salmon (). The present study was designed to evaluate the wound healing effects of -derived PDRN for injection (Rejuvenex) and PDRN cream (Rejuvenex Cream) in comparison with those of -derived PDRN injection (Placentex).

Mixed Tumor in Deep Lobe and Versatility of Acellular Dermal Matrix.

Frey's syndrome and infra-auricular depressed deformities are the ones of the most common complications that can occur after total parotidectomy. We report 1 case of pleomorphic adenoma occurred in the deep lobe that obtained good results from using acellular dermal matrix (ADM) after total parotidectomy. A 24-year-old man visited the hospital with oval shape mass in right mandibular angle which of 4 cm in size was found in the deep lobe of right parotid gland from Magnetic resonance imaging scanning and a pleomorphic adenoma was suspected.

Chondroid Syringoma on Face.

Chondroid syringoma is a rare mixed tumor of the skin which is composed of both mesenchymal and epithelial cells. Its incidence at less than 0.1% and is frequently located on the head and neck.

Osteomyelitis following Domestic Animal Bites to the Hand: Two Case Reports and Practical Guidelines.

Recently, the number of cases of animal bite wounds has increased significantly in concordance with an increase in the pet population around the world. The authors report two rare cases of osteomyelitis of the phalanx following cat and dog bites. On initial physical examination, signs of a severe infection were observed.

Effect of Low-Level Laser Therapy on Human Adipose-Derived Stem Cells: In Vitro and In Vivo Studies.

Background: Low-level laser therapy (LLLT) continues to receive much attention in many clinical fields. Also, LLLT has been used to enhance the proliferation of various cell lines, including stem cells. This study investigated the effect of LLLT on human adipose-derived stem cells (ADSCs) through in vitro and in vivo studies.
