体内研究：
Octreotide-treated groups show a significant reduction in the tumor volume compared to the saline group. Octreotide-PPSG (1.4 mg/kg, i.p.) shows greater antitumor effect than Octreotide-soln (100 μg/kg, i.p.). Octreotide-treatments results in significant inhibitory effect on the expression levels of SSTR2 and SSTR5 in primary HCC-bearing rats compared with the saline group. Octreotide-PPSG appears to inhibit the expression of SSTR2 and SSTR5 to a greater extent than that of Octreotide-soln treated group. A test dose of octreotide acetate significantly decreases the serum gastrin level to approximately one third of the baseline in 2 hr and the effect lasted approximately for 6 hr. On day 21, treatment with sustained-release formulation of octreotide acetatea (5 mg intramuscular, q 4 wk) is initiated. |

动物实验：
Octreotide (acetate) is formulated in saline.MiceThirty mice with HCC xenografts are randomLy divided into three groups: (A) Octreotide-soln group, (B) Octreotide-PPSG group, and (C) control group. Octreotide-soln group receives i.p. injection of 100 μg/kg octreotide-soln once a day and totally for consecutive 14 days. Octreotide-PPSG group receives a single subcutaneous injection of 1.4 mg/kg Octreotide-PPSG, and the injection volume is about 0.2 mL. Control group receives i.p. injection of saline once a day for consecutive 14 days. Treatment starts on the next day after injection of H22 hepatoma cell suspension and maintains for 14 days. Tumor growth is monitored by periodic caliper measurements on day 7 and day 14 post seeding. Tumor volumes (V) are calculated based on the length and width of tumor by Eq. RatTwelve male SD rats are divided into two groups, and housed in standard cages at 25°C, with free access to food and water for a week prior to the experiment. Rats are subcutaneously injected with Octre |
