Dental pulp stem cells (DPSCs) are a type of adult stem cell present in the dental pulp tissue. They possess a higher proliferative capacity than bone marrow mesenchymal stem cells. Their ease of collection from patients makes them well-suited for tissue engineering applications, such as tooth and nerve regeneration. Chios gum mastic (CGM), a resin extracted from the stems and leaves of Pistacia lentiscus var. Chia, has garnered attention for its potential in tissue regeneration. This study aims to confirm alterations in cell proliferation rates and induce differentiation in human DPSCs (hDPSCs) through CGM treatment, a substance known for effectively promoting odontogenic differentiation. Administration of CGM to hDPSC cells was followed by an assessment of cell survival, proliferation, and odontogenic differentiation through protein and gene analysis. The study revealed that hDPSCs exhibited low sensitivity to CGM toxicity. CGM treatment induced cell proliferation by activating cell-cycle proteins through the Wnt/β-catenin pathway. Additionally, the study demonstrated that CGM enhances alkaline phosphatase activation by upregulating the expression of collagen type I, a representative matrix protein of dentin. This activation of markers associated with odontogenic and bone differentiation ultimately facilitated the mineralization of hDPSCs. This study concludes that CGM, as a natural substance, fosters the cell cycle and cell proliferation in hDPSCs. Furthermore, it triggers the transcription of odontogenic and osteogenic markers, thereby facilitating odontogenic differentiation.

PURPOSE: This study was performed to examine vascular pain due to gemcitabine and according to clinical factors. METHODS: The survey was performed with 525 cancer patients visiting chemotherapy infusion room in one general hospital. The data were collected via self-reported questionnaire, researchers observation, and reviewing medical records. Data were analyzed descriptive statistics, t-test, Kruskal-Wallis test, Tukey test using ranks, Jonckheere-Terpstra test, and Spearman correlation analysis were used. RESULTS: The mean scores of the intensity and onset time of vascular pain were 3.06+/-2.16 and 8.13+/-13.13 min, and each other were negative correlaton. Degree of intensity of vascular pain had a significant difference on gender (p=.003), age (p=.004), weight (p=.019), Body mass index (BMI) (p=.005), Body surface area (BSA) (p=.030), infusion time (p<.001), dose (p=.027), dose per minute (p<.001), the number of administered gemcitabine (p=.005), combination chemotherapeutic drug (p=.013) and tumor type (p=.002). Degree of onset time of vascular pain had a significant difference on infusion time (p=.044), combination chemotherapy (p=.001) and injection site (p=.001). CONCLUSION: Patients administrated gemcitabine were experiencing various vascular pain, and vascular pain had a difference on clinical factors. Therefore, oncology nurses should be considered significant clinical factors to implement effective interventions to patients administered gemcitabine.

OBJECTIVES: The purpose of this study was to estimate the normal blood lead (PbB) levels in a group of Korean subjects and to evaluate the association between PbB levels and habitual tobacco and alcohol use. METHODS: We recruited 532 adults (320 males and 212 females) with no history of occupational exposure to lead, as study subjects. RESULTS: PbB levels ranged between 0.43 microgram/dl and 9.45 microgram/dl. The adjusted geometric mean PbB in men was 3.19 microgram/dl, which was significantly higher than that seen in women: 2.66 microgram/dl (P=0.017). Geometric mean PbBs were not significantly different between urban and rural patients. The adjusted geometric mean PbB in smokers was 3.31 microgram/dl, which was significantly higher than that seen in nonsmokers: 2.64 microgram/dl (P=0.035). The adjusted geometric mean PbB in drinkers was 3.10 microgram/dl, which was significantly higher than that seen in non-drinkers: 2.75 microgram/dl (P=0.049). CONCLUSIONS: The PbB levels of some Korean adults seem to be comparable to those seen in foreign countries. Our results suggest that tobacco and alcohol cessation will be helpful in decreasing the harmful effect of lead.

Twin Pregnancies are increasing these days due to recent development of the technology in treating infertility. twin pregnancies tend to cause more congenital anomalies than singleton pregnancies do. Especially when twin pregnancies are affected with one anomalous fetus combined to a normal one, the proper management and counseling are difficult. We experienced a twin pregnancy in which one anencephalic fetus was combined to a normal one, after close counseling we decided to continue the pregnancy. At 35 weeks 6 days of gestation, an anencephalic fetus was dead, so we delivered by cesarean section due to breech-cephalic presentation. The birth weight of the normal and anencephalic fetuses were 2160 gm and 600 gm, respectively. The anencephalic fetus was combined with scoliosis, absent left upper limb, and nuchal skin defect, but the healthy one showed good crying and movement and its Apgar score was 8 in 1 minute and 9 in 5 minute. Although the infant needed intensive care for 21days in the nursery room, she was finally discharged in good condition. We present this case with a brief review of the literature.

Dermatofibrosarcoma protuberans (DFPS) is a locally aggressive skin tumor with a very low incidence in the general population. This tumor has a remarkable tendency to recur, However, a metastasis is rare. We report a case of DFPS with a pulmonary metastasis in 28-year-old man. The pulmonary metastasis developed 5 years after a complete resection of the primary skin tumor. We reviewed the clinical manifestations and treatment of DFPS, and highlight the need for a long-term follow-up examination for metastases after a wide excision of these lesions.
