Objective To observe the attenuated effect of Kanglaite Injecti on (KI) combined with chemotherapeutic drugs on transplanted human lung cancer A54 9 in nude mice. Methods Ninety- six nude mice were transplanted subcutaneousl y with human lung cancer A549; 7 days later, the mice were randomized into 16 gr oups(n=6) and were given antitumor drugs according the regimen. Other 12 normal mice were used as controls. KI groups were given KI 1.25, 2.5 and 5.0 g/kg respe ctively and were administered (iv) continuously for 10 times on 7th day of trans plantation; cisplatin (DDP, 1.5 mg/mg or 3 mg/kg) and Gemzar (30 mg/kg or 60 mg/ kg) were given one dose by intraperitoneal injection on 10th day of transplantat ion; Gemzar was given again 4h after medication of DDP. Taxotere (25 mg/kg) was given one dose by intraperitoneal injection on 7th day of transplantation. The m ice were killed to examine the body weight, tumor weight and tumor- inhibiting rate. Results KI 1.25, 2.5 and 5.0 g/kg respectively combined with DDP 3mg/kg and Gemzar 60 mg/kg had a better inhibitory effect on the growth of human lung c ancer A549 than KI, DDP and Gemzar alone. KI in three doses respectively combine d with DDP 1.5 mg/kg and Gemzar 30 mg/kg not only had a better inhibitory effect than those of KI, DDP and Gemzar alone, but also promoted the antitumor actions . The tumor- inhibitory rate of KI in three doses respectively combined with Ta xotere (25 mg/kg) was higher than KI and Taxotere alone. Conclusion KI combine d with DDP and Gemzar or with Taxotere can shorten the tumor mass and has tumor - inhibitory and attenuated effect.

Objective To observe the preventive and therapeutic effect of Ka ng laite Injection (KI) on acute nephrotoxicity in rats induced by cisplatin (DDP) and gemzar.Methods Forty SD rats, male and female in a half, were randomized in to normal control group, KI group, DDP+ Gemzar group and KI+ DDP+ Gemzar gro up, 5 male and 5 female in each group. The KI+ DDP+ Gemzar group were given K I 10 mL/kg first,DDP injection 6 mg/kg 2 hours later and Gemzar injection 90 mg/ kg 4 hours later. After treatment, acute nephrotoxicity was observed.Results On e week after treatment, all of the rats survived; the body weight of the male an d female rats in group was similar in KI group and in the normal control group, but lower in DDP+ Gemzar group, in particular the male rats, than that in norma l control group. Body weight in KI+ DDP+ Gemzar group was lower than that in the normal control group but higher than that in DDP+ Gemzar group.The serum le vels of biochemical parameters were similar in KI group and the normal control g roup; serum levels of total protein (TP) and albumin(ALB) were markedly lower bu t those of blood urea nitrogen (BUN) and creatine (CRE) higher in DDP+ Gemzar g roup than those in the normal control group; the above indexes were improved in KI+ DDP+ Gemzar group as compared with those in DDP+ Gemzar group and arrive to the normal level.Conclusion KI has preventive and therapeutic effect on acu te nephrotoxicity in rats induced by DDP and Gemzar.

AIM　To study the effect of lidamycin on the expression of genes involved in invasion regulation in HCT-8 human colon cancer cells. METHODS　HCT-8 human colon cancer cells were treated with lidamycin (10 nmol*L-1) for 8 h. The effect of lidamycin on the expression of genes were detected by cDNA arrays, Northern blot and RT-PCR. RESULTS　Hybridization of the entire cDNA populations to Atlas Arrays showed that lidamycin down-regulated the expression level of MMP-9 and up-regulated the expression level of TIMP-1. These changes were confirmed by Northern blot and RT-PCR. CONCLUSION　The results indicate that lidamycin may exhibit its anti-invasive activity by inhibitting the production of type IV collagenase whilst enhancing the production of tissue inhibitor metalloproteinase.
