AIM To study the therapeutic effect of bone marrow transplantation on mustard gas-poisoned mice. METHODS Mustard-poisoned mice model was constructed by injected mustard gas 20 mg·kg~(-1) subcutaneously. At 4 h, 1 d and 2 d after poisoned by mustard gas, the suspended bone marrow cells (106 cells per time) were injected into mice respectively. After poisoned 3, 5, 7 and 10 d, the numbers of leukocyte and marrow nucleated cells were recorded periodically. At the same time, after poisoned 4 h and 1 d by mustard gas, mice in another group were injected granulocyte colony stimulating factor (G-CSF) 74 μg·kg~(-1) combined with transplantation and changes of the cell number were observed. RESULTS Compared with poisoned group without transplantion, leukocyte number in bone marrow transplanted group presented ascending trend, but there was no statistical significance until the 10 d after poisoned. However, the number of marrow nucleated cell increased significantly from the 5th day. After mice injected bone marrow cells combined with G-CSF, leukocyte increased markedly in earlier stage compared with transplantation only. CONCLUTION The bone marrow transplantation has significant effects on improvement of marrow hematogenic system inhibited by mustard gas.

OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.
