Objective To evaluate the effects of the recombinant human interleukin-1 receptor antagonist(rhIL-1ra)on a toluene-2, 4-diisocyanate (TDI)-induced guinea pig allergic rhinitis (AR)model. Methods An AR model was established via sensitization and challenge of two-step procedure using TDI in guinea pigs. Normal animals were treated only with the olive oil(TDI vehicle). Sixty adult guinea pigs were randomly divided into six groups (n=10): normal group, model group (rhIL-1ra vehicle), positive control group (budesonide, 25.6 µg/kg), rhIL-1ra treated groups (rhIL-1ra 50, 100 and 200 µg/kg, respectively). From day 8 after sensitization, animals of all the groups were treated respectively with the agents or vehicle once a day for 14 days. During the observation period, the index of clinic score was recorded for every animal. At day 14 of the dosing, guinea pigs were sacrificed 30 min after the last TDI challenge and observation. Blood samples were taken from the abdominal aorta to prepare the serum for detection of histamine, and the nasal mucosase were dissected for histamine detection and histopathological observation. Results Compared with the guinea pigs in normal group, those in the model group exerted the typical symptoms of AR. It was shown that rhIL-1ra could improve nasal symptoms and cause a significant decrease in the instances of nasal sneezing as well. In addition, rhIL-1ra significantly reduced the concentrations of histamine in the nasal mucosa and IgE in the blood compared with those in the model group (P<0.05). Moreover, the pathological results showed that less edema, vasodilation and inflammatory cell infiltration were found in the nasal mucosa after rhIL-1ra application. Budesonide also showed the above effects with no significant difference compared with rhIL-1ra. Conclusion A guinea pig allergic rhinitis model is successfully induced by TDI. The results indicated that rhIL-1ra(50-200 µg/kg)is effective in improving allergic rhinitis. Our findings indicated that rhIL-1ra might serve as a potential new drug for allergic rhinitis therapy.

· AIM: To study the in situ relative intraocular position of the iris-claw phakic intraocular lens (PIOL)for high myopia using an anterior chamber optical coherence tomography (AC OCT)prototype.· METHODS: Six PIOLs (11.50 to 22.00D lens powers) were implanted in phakic myopic eyes. Using AC OCT, tomography was taken in the anterior chamber to measure the preoperative anterior chamber depth, postoperative distance between the PIOL and the corneal endothelium (endothelial-optic distance), and the postoperative distance between the PIOL and the crystalline lens.· RESULTS: Preoperative anterior chamber depth ranged from 3.27 to 3.91 mm and the postoperative endothelial-optic distance measured 2,07 to 2,24 mm. The distance between the crystalline lens and the posterior surface of the IOL ranged from 0.82 to 1.32 mm. Several tomography revealed the position of the PIOL on the iris, The pigment layer of the iris did not seem to be disturbed by the presence of the PIOL.· CONCLUSION, The original anterior chamber depths were reduced by 36,1% to 44.6% after implantation. This study of 6 eyes revealed that tomography taken by AC OCT are useful in verifying the intraocular position of the PIOL within the anterior chamber. Adequate space was maintained between the iris-fixated phakic intraocular lens and the corneal endothelium, angle, and crystalline lens.

A protocol for the isolation, purification and culture of motor neurons from newborn rat spinal cord was described and the effect of glial cell line-derived neurotrophic factor (GDNF) on the growth of neurite of motor neurons was investigated in vitro. Spinal motor neurons (SMNs) were dissociated from ventral spinal cord of postnatal day 1 rats. The culture system for SMNs was established by density gradient centrifugation, differential adhesion, and use of serum-free defined media and addition of exogenous GDNF. After 72-h culture, the cells displayed the characteristic morphology of motor neurons, exhibited extensive neuritic processes and were positive for choline acetyltransferase (ChAT) expression. The neurite length of SMNs in GDNF groups was significantly longer than that in control group (P<0.05). This protocol can be adapted for various postnatal motor neurons studies.
