The work aims to study the drug metabolizing enzymes involved in the metabolism of butylphthalide and evaluate the induction and inhibition activities of butylphthalide on CYP450 isoenzymes by using in vitro (liver microsome incubation system of rats and human) and in vivo (CYP induced model of rats) method. Butylphthalide was incubated with selective inhibitors of CYP450, and its metabolic rate was determined to identify the metabolizing isoenzymes of NBP in rat (normal and induced rats) and human liver microsomes. The in vitro inhibition effect of butylphthalide on 6 main liver microsomal CYP450 isoenzymes was evaluated by using probe drugs; the induction and inhibition activities in vivo of butylphthalide on CYP450 isoenzymes were evaluated by NBP ig dosing (160 mg x kg(-1)) and iv dosing (20 mg x kg(-1)) in rats. After adding the specific inhibitors of CYP2C11, 2E1 and 3A 1/2 for rat, CYP2C19, 2E1 and 3A4/5 for human, the metabolism of NBP in rat and human liver microsomes were reduced 38.8%, 86.2%, 78.4% and 51.0%, 92.0%, 58.9% of control, respectively. The metabolic rates of NBP in CYP2E1 and 3A 1/2 induced rat liver microsomes were increased 25.5% and 68.9%. High concentration of NBP (≥ 200 μmol x L(-1), in vitro) could inhibit the activities of CYP1A2, 2C6, 2C11 and 2D2 in rats, and high concentration of NBP ( ≥ 15 μmol x L(-1), in vitro) could inhibit the activity of CYP2C19 in human. All the results indicated that NBP should be mainly metabolized by CYP2E1, 2C11 and 3A 1/2 in rats and CYP2E1, 2C19 and 3A4/5 in human. High concentration of NBP could inhibit human CYP2C19 in vitro. No significant induction/inhibition effects of NBP were observed on rat liver CYP450 isoforms after ig 160 mg x kg(-1) NBP or iv 20 mg x kg(-1) NBP.

· AIM: This study was designed to evaluate the effectiveness of anterior lens capsule inclusion in combined trabeculectomy and cataract surgery in preventing scar formation of the filtering bleb in rabbit model.· METHODS: Twerty-Four eyes (12 rabbits) with glaucoma model were studied, anterior lens capsule inclusion in trabeculectomy with the small-incision cataract surgery were performed on all right eyes (experimental group) and no implants were applicator in trabeculectomy with the small-incision cataract surgery on all left eyes (control group). These operated eyes were followed up from day 1 to 6 months postoperatively. Intraocular pressure (IOP) was measured and filtering blebs were observed after surgery. Other main outcome measures: cornea、conjunctiva、formation of the anterior chamber, anterior chamber depth、inflammatory reaction、achievement ratio of operation and complications were analyzed. On week 1, 2, 4, 12 and 24 after surgery the animal were killed in batch. Tissue was harvested from the bleb area and was made pathological section. HE staining、light microscope and micro photo analysis technique were applied to observe the cytological and histopathologic characteristics of the filtering tunnels.· RESULTS: There were significant differences between the two groups on IOP (1, 2, 4 weeks)、filtration bleb, achievement ratio of operation and complications. In experimental group, at the first month postoperatively, anterior lens capsule absorption started with inflammatory characteristics. The peak of inflammatory reaction occurred 1 week after operation and all the cells in the filtrating tunnel disappeared 6month after surgery. The fibroblast proliferation in control group occurred at I week and the filtrating tunnel closed with angiogenesis at 1 month after surgery. Fibroblast proliferation started 1week after surgery with no statistical difference during the time course (P >0.05). Significant statistical differences were observed by comparing the fibro blasts numbers per unit area in the filtrating tunnel in experimental group and those in control groups (P<0.05).· CONCLUSION: Anterior lens capsule was totally absorbed at 6 months postoperatively. Anterior lens capsule inclusion in trabeculectomy with cataract surgery can possibly control intraocular pressure effectively, long-term sustainability of functional filtration bleb, inhibition of the proliferation of fibroblasts and opening of the filtrating pathway in the experimental animal models were satisfied. Compared to the control group, anterior lens capsule application has less complication.

Objective To study the expression level of thyroid insulin-like growth factor-Ⅰ (IGF-Ⅰ) in iodine deficiency and excess mice and the effect of thyroid gland IGF-Ⅰ in the thyroid morphological change. Methods Forty-eight Balb/c mice were chosen as studied objects,weighing about 16 g. They were divided into three groups: low iodine(LI,iodine content of 50 μg/kg in feed,drinking deironized water) group,normoi(NI,iodine content of 300 μg/kg in feed,drinking deironized water) group and high(HI,iodine content of 300 μg/kg in feed,iodoine of content 14 700 μg/kg in drinking) group,16 mice in each group. Mice were put to death after 12 weeks and taken out of their thyroid gland. The body weight,absolute and relative weights of thyroid gland were measured and the morphological change of thyroid gland were observed under microscope. The expression levels of thyroid gland IGF-Ⅰ mRNA and protein were detected by RT-PCR and immunohistochemistry,respectively. Results There were statistical significances between groups of thyroid absolute and relative weights(F = 315.881,405.921,all P < 0.01). LI group [(10.71±4.03) mg,(44.98±15.39)mg/100 g body weight]and HI group [(3.42±1.17)mg,(13.50± 3.89)mg/100 g body weight]had heavier thyroid absolute and relative weights than NI group[(2.11±0.53)mg,(8.35±1.98)mg/100 g body weight,all P < 0.01]. Under microscopy,the thyroid follicle capacity grew down and the follicle quantity grew up in LI group,the epithelium was stylolitic,the colloid diminished or absence in follicular cavity,while HI group presented colloid accumulation without follicular hyperplasia. The expression level of thyroid gland IGF-Ⅰ mRNA in LI group(1.03±0.32) was more than that in NI(0.65±0.19) and HI(0.59± 0.20) groups(F= 7.518,P< 0.01). In contrast to NI,there was no difference in the expression level of thyroid gland IGF-Ⅰ mRNA in HI group(P > 0.05). The brownish particles of LI group were more than NI and HI groups in the thyroid follicle epithelium by immunohistochemistry,while HI group was less than NI group. Conclusions The mice of iodine deficiency presented follicular hyperplasia goiter,the mice of iodine excess presented colloid accumulative goiter. The change of IGF-Ⅰ mRNA and protein expression may participate morphologleal change,indicating autocrine IGF-Ⅰ of thyroid gland may play an important role in regulating goiter formation.
