This study was undertaken to document the effect of transforming growth factor-beta2 (TGF-beta2(TGF-beta2) and basic fibroblast growth factor (bFGF) on the proliferation of pig retinal pigment epithelial cells (RPE). Whereas bFGF increased the proliferation, TGF-beta2 showed the inhibitory effect on the proliferation The inhibitory effect of TGF-beta2 disappeared in RPE subcultured with 10ng/ml of bFGF. Both TGF-beta2- and bFGF-specific antisense oligonucleotides blocked the autocrine effect of the growth factors. PLC-71 -specific antisense oligonucleotide inhibited the effect of TGF-beta2 and bFGF. Genistein inhibited the effect of TGF-beta2 and bFGF in dose-dependent man, ner. The data suggest the involvement. of in PLC-/1 and tyrosine kinase in signalling.

From February 1996 to May 1997, 18 patients underwent mitral valve repair for mitral regurgitation. There were 9 male and 9 female patients aged from 19 to 68 years (mean, 53). Thirteen patients were in New York Heart Association (NYHA) class III and IV. The cause of mitral regurgitation was degenerative in 12 patients, rheumatic in 5 patients and infective in 1 patient. Fifteen patients were in Carpentier's functional classification II, 2 patients in Carpentier's class III and 1 patient in Carpentier's class I. Surgical procedures included prosthetic ring annuloplasty (16 cases), rectangular resection of posterior leaflet (15 cases), chordal shortening (5 cases), triangular resection of anterior leaflet (2 cases), commissurotomy (2 cases), partial transposition of posterior leaflet (1 case). These procedures were combined in most patients. There was no operative death. These patients have been followed from 1 to 15 months, mean of 6.7 months. There was one late death resulted from low cardiac output following mitral valve replacement. The function of the repaired valve in other 17 patients has remained satisfactory during the observed interval. We consider that mitral valve repair is highly satisfactory in patients with mitral regurgitation.

Lectin is a non-immunological glycoprotein and binds specifically to carbohydrate terminals in tissue. Lectin histochemistry using 10 different biotinylated lectins was performed to investigate the effects on thirty-two pigmented rabbit retinas during wound healing. The results are as follows: 1) In normal retina. a) WGA, RCA I, and LCA were bound to the internal limiting membrane. b) WGA, RCA I, LCA, and PNA were bound to the photoreceptor layer. c) WGA, RCA I, LCA, SJA, ConA and BSL I were bound to the basal side of retinal pigment epithelium. d) PNA was bound to cone cell only. e) SBA, DBA, and UEA I didn't bind to any layers of retina. 2) In photocoagulated wound. One day after photocoagulation WGA, LCA and RCA I began to show increased reaction. At 3 and 5 days these lectins sustained reactivity. At 7 days increased reactivity began to decrease or disappear from wound. Macrophages had positive reaction to BSL I, WGA, LCA, and RCA I. In conclusion these results indicate that a-mannose, a glucose, a, beta-galactose, N-acetylglucosamine, and N-acetylneuramic acid are present in glycoconjugates of normal rabbit neural retina. It seems that some glycoconjugates may be related to vitreoretinal, retinal and chorioretinal adhesion in normnal retinal, and after argon laser photocoagulation. WGA-binding, LCA-binding and RCA I-binding glycoconjugates may play a part in cell adhesion during early wound healing.
