Objective To investigate the effect of botulinum toxin type A injection on the expres-sion of substance P, TGF-β1 and α-SMA in rabbit ear model of hypertrophic scar. Methods The hyper-trophic sear model was established in 24 Japanese rabbits'ears. The wounds in ventral surface of ear were divided in Group I (lateral wounds) and Group S (medial wounds), 3 wounds each side per ear, totally 72 wounds each group. The wound-healing time and the growth of scar were observed and recorded. On post-wounding day 28, the wounds were created in another 6 rabbits in the same way and the normal skin were harvested as Group C. Likewise, the scar samples in Groups I and S were harvested. The mRNA expression of substance P, TGF-β1 and α-SMA were detected quantitatively by using real-time PCR and α-SMA was also detected with Western blot. Results No difference between the ratio of healed or infec-tious wounds on post-wounding day 14. The mRNA expression of SP, TGF-β1 and α-SMA in Group I was significantly lower than Group S, but higher than those in Group C (P<0. 01 and <0. 05, respec-tively). The blot density of α-SMA and the ratio of blot density of a-SMA to β-actin in Group I were be-tween that of the other two groups. Conclusion Without delaying the wound-healing, botulinum toxin type A injection significantly decreases the expression of SP, TGF-β1 and α-SMA in rabbit ear model of hypertrophic scar.

Objective To observe the changes in NO content and NOS activity of serum and the testis in Wistar rats with type I diabetes mellitus. Methods 63 rats were randomly divided into control group(C) and diabetes group(D). Diabetes was induced by intraperitoneal injection of Alloxan. Rats with diabetes were observed for 1 week(D 1), 2 weeks(D 2), 3 weeks(D 3), 4 weeks(D 4), 5 weeks(D 5), 6 weeks(D 6), 7 weeks(D 7) and 8 weeks(D 8), respectively, and they were sacrificed at the end of each observation period. Serum was obtained and testis homogenates were prepared, and the levels of NO content and NOS activity of them were determined respectively. Results Compared diabetes group with control group, NO contents and NOS activity of serum from diabetic rats were higher, then NOS activity began to decline to approach the control level. In the testis homogenates, NO content dropped slightly after injection of Alloxan, while NOS activity showed no significant change. Thereafter, both NO content and NOS activity of testis homogenates were increased. Conclusion There are changes in NO content and NOS activity of serum and testis of rats after diabetes are induced with Alloxan.

Methods 21 rats were divided into control group(C), diabetes group(D) and treatment group (T) at random. Diabetic model was reproduced by intraperitoneal injection of alloxan. After having been treated with Jinshuibao capsule for 8 weeks, serum levels of glucose, insulin, testosterone and levels of high energy phosphate compound, MDA, SOD, GSH-Px, and ATPases in the testis were determined respectively. Results Compared with control group, testicular mitochondria showed lipid peroxidase injury, with disturbed energy metabolism, and the activity of ATPases was lowered. All the changes in serum and testes were improved when Jinshuibao capsule was given. Conclusion Mycelium of cultured Cordyceps sinensis might have protective effects on the testis in diabetic Wistar rats.

[ABSTRACT]AIM:ToevaluatetheeffectsofantisenseTGF-β1oligodeoxynucleotide(ASTGF-β1)ontheex-pression of TGF-β1 , deposition of extracellular matrix ( ECM) and the neointima formation in the arteries after balloon inju-ry.METHODS:The unmodified and phosphorothioate-modified AS TGF-β1 which containing 15 bases and surrounding the initiation codon region (ATG) of rat TGF-β1 complementary DNA (cDNA) were designed.At the same time, sense TGF-β1 oligodeoxynucleotide ( S TGF-β1 ) with the base sequence complement to AS TGF-β1 was synthesized as a control . The oligodeoxynucleotides were introduced into in vivo and in vitro experiments , respectively .RESULTS:The AS TGF-β1 significantly inhibited the protein expression of TGF-β1 in a concentration-dependent manner , and S TGF-β1 did not have the same effect.Furthermore, no effect of the AS TGF-β1 on the mRNA expression of TGF-β1 in injured VSMCs was ob-served.Moreover, for the injured VSMCs, AS TGF-β1 significantly and concentration-dependently inhibited the basal DNA synthesis.Both AS TGF-β1 and S TGF-β1 did not exhibit dose-dependent effects on DNA synthesis in uninjured VSMCs . Fibronectin ( FN) mRNA expression in injured VSMCs was significantly decreased by AS TGF-β1 in a concentration (0.01~1 μmol/L)-dependent manner .AS TGF-β1 significantly increased the mRNA expression of contractile marker SM 22α, and decreased the mRNA expression of synthetic markers osteopontin and matrix Gla , especially at the concentration of 0.01μmol/L and 0.1 μmol/L.After treatment with AS TGF-β1 (90 μg· kg-1 · d-1 ) for 28 d, the neointima formation was significantly inhibited , and the area ratio of intima/media was markedly decreased by 68% compared with untreated group , but S TGF-β1 had no effect on neointimal formation .CONCLUSION:The AS TGF-β1 specifically inhibits the pro-tein expression of TGF-β1 in the VSMCs derived from injured arteries .Moreover , it significantly inhibits DNA synthesis and cell proliferation, and decreases the expression of FN .Therefore, AS TGF-β1 dramatically attenuates neointima formation after balloon njury .The effects of AS TGF-β1 on the injured VSMCs may be associated with its reverse effects on the altera-tion of VSMC phenotype after balloon injury .
