AIM: To establish an animal model for studying the development and metastasis of melanoma. METHODS: C57BL/6 mice were used as host to receive melanoma cell transplantation. Three kinds of melanoma cell lines, B16F0, B16F1 and B16F10, cultured to prepare the cell suspensions, were transplanted into the mouse anterior chamber (AC) of the eye. The time of eyeball diabross, time of survival and metastasis of lymph node and lung were observed. RESULTS: The time of eyeball diabross in F10 group was earlier than that in other groups. The time of eyeball diabross was no difference between F0 and F1 groups. Metastasis was developed 18 days after transplantation in F1 and F10 groups, where the tumor cells was found in ipsilateral cervical lymph nodes. The melanoma cells metastasized to lung in all three groups 28 days after transplantation. The survival time in F0 group was longer than F1 and F10 groups. There was no difference in survival times between F1 and F10 group. CONCLUSION: The differences of three kinds of melanoma cell lines in tumor development and metastasis provided the evidence that was useful for choosing suitable animal model further to study the eye melanima.

OBJECTIVE:To study the protective effects of total flavone from Prunus cerasifera fruits(PCE)on alcoholic liver disease(ALD)in rats,and provide experimental basis for developing new medicines for anti-ALD. METHODS:40 rats were ran-domly divided into normal group(distilled water),model group(distilled water),silibinin group [positive control,30 mg/(kg·d)] and PCE high-dose,low-dose groups [80,40 mg/(kg·d)],8 in each group. All rats were intragastrically administrated(10 mL/kg) every morning,once,for 6 weeks;meanwhile,except for normal group,rats in other groups received 50% alcohol(10 mL/kg) once intragastrically every afternoon to induce ALD model. After administration,heart,liver,spleen and other organ indexes,sub-cutaneous fat,brown fat,abdominal fat indexes were determined,as well as serum biochemical indexes [glutamate transaminase (ALT),aspartate aminotransferase(AST),total bilirubin(TBIL),direct bilirubin(DBIL),indirect bilirubin(IBIL),gamma-glu-tamyl transpeptidase(GGT),and total cholesterol(TC),triglyceride(TG),high-density lipoprotein(HDL),low-density lipopro-tein (LDL)] level and liver biochemical indexes [superoxide dismutase (SOD),malondialdehyde (MDA),glutathione peroxidase (GSH-Px),TC,TG] and TC,TG levels in feces;pathological changes of liver and kidney tissues were observed. RESULTS:Compared with normal group,heart,liver,spleen indexes,subcutaneous fat,abdominal fat indexes in model group were in-creased(P<0.05 or P<0.01),brain index and brown fat index were decreased(P<0.05);HDL level and HDL/TC ratio in serum were decreased,other serum indexes were increased(P<0.05 or P<0.01);SOD,GSH-Px levels in liver tissue were decreased, other above-mentioned liver biochemical indexes were increased(P<0.01);TC,TG levels in feces were increased(P<0.01);liv-er and kidney showed obvious lesions. Compared with model group,the above-mentioned indexes in silibinin group and PCE high-dose group were significantly improved (P<0.05 or P<0.01);ALT,AST in serum and MDA level in liver tissue in PCE low-dose group were significantly decreased(P<0.01),and SOD,GSH-Px levels in liver tissue were significantly increased(P<0.05);lesion degree of liver and kidney and lipid accumulation in liver were reduced in administration groups. CONCLUSIONS:PCE may play a role in anti-ALD by anti-oxidation,promoting liver cell regeneration and regulating lipid metabolism.
