AIM To observe the effect of topical 0. mL/Kg). The right lacrimal gland of each rat was exposed under a surgical microscope and injected with 0.1 mL (20 milliunits, mU) of botulinum-B. Animals were fed a regular diet. The animals had free access to food and water and they were on a 12h light/dark cycle. Group A rats were treated with 0.05% CsA eye drops three times daily and group B were treated with 0.1% sodium hyaluronate eye drops three times daily, beginning three times after injection. Control group rats weren’t treated. Rats had been sedated using fundamental basal and anesthesia rip movement was assessed with Schirmer pieces on times 1, 3, 7, 14, and 42 post-injection. The Shirmer remove was placed in the lower eyelid for 5min, acquiring care in order to avoid corneal excitement, and the quantity of wetting was assessed in millimeters. Corneal fluorescein staining was examined 1min after fluorescein instillation utilizing a slit light having a cobalt blue light. Corneal staining was obtained from 0 to 4 the following: 0) no AWZ1066S fluorescein stain; 1) 1/8 of corneal surface area stained; 2) 1/4 of corneal surface area stained; 3) 1/2 of corneal surface area stained; 4) 1/2 of corneal surface area stained. Rats had been euthanized at 3 arbitrarily, 7, 28, and 42d post-procedure (particular amounts of rats from each group). The lacrimal glands had been immediately eliminated and set in 4% paraformaldehyde for 24h. The lacrimal glands had been paraffin-embedded after that, sectioned and stained immunohistochemically, followed the guidelines. Rabbit anti-lacritin (Santa Cruz), diluted 1:50 in PBS-T; mouse nestin (Chemicon), diluted 1:200 in PBS-T; goat DCX (Santa Cruz), diluted 1:100 in PBS-T; mouse NeuN (Chemicon), diluted 1:300 in PBS-T; and mouse GFAP (Chemicon), diluted 1:500 in PBS-T had been added detail by detail and the areas incubated overnight at 4C. Biotin-labeled rabbit IgG (Vector, US) secondary antibody, diluted 1:200 in PBS-T, was then added and the sections were incubated for 1h at room temperature. ABC complex (Vector) was prepared 1h before use, then added to the sections and the sections were incubated for 1h at room temperature and developed using DAB (Zhongshan Jinqiao Biotechnology Co., Ltd., China). The sections were dehydrated, cleaned, and sealed with a neutral gum. Immunofluorescence staining using AWZ1066S the primary antibody was performed as above. The working concentration of FITC-labeled secondary antibody (Zhongshan) was 1:200. The cells were incubated in the dark at room temperature for 2h. The nuclear fuel DAPI was added before mounting. The target site was photographed using a BX51 fluorescence microscope for qualitative observation of lacritin protein expression. After coloration of each tissue section, the target area was selected under the microscope, keeping the brightness of the light source constant. The white balance was set using a blank area of the tissue section and the resolution, magnification, and scale size of the photograph were recorded. Fluorescent stained sections were photographed using a BX51 fluorescence microscope (Olympus) and the black balance was set using a non-tissue site. The principle of the slice was the same as above. Rats were LAMA euthanized and then the lacrimal glands were quickly removed and placed on ice. An appropriate amount of lysate was added (100 L of lysate per 5 mg of tissue). The tissue was cut into pieces using an ophthalmic scissors and crushed with a mechanical tissue crusher. Lastly, the tissue was placed in an ice bath and completely crushed using a sonicator (72 kJ, 20% amplitude, ultrasonic 5s, intermittent 25s, total 5min) and centrifuged at 12 000 g for 10min at 4C. The supernatant was then transferred to another pre-chilled Eppendorf tube and stored at -80C. The extracted homogenate supernatant was subjected to protein quantification using the Bradford method. Here, 15 g samples, mixed with an equal volume of 2loading buffer, were bathed in boiling water at 100C for 2min. AWZ1066S Samples were loaded on a polyacrylamide gel, electrophoresed at 200 V, and transferred to a PVDF membrane. Blots were blocked for 1h at room temperature, incubated with anti-rat lacritin protein antibody, diluted 1:300 in the blocking solution, overnight at room temperature, rinsed with PBS-T (310min), and incubated with goat anti-rat IL-6 monoclonal antibody (PeproTech, USA) diluted 1:2000 in PBS-T for 2h at room temperature. Blots were rinsed with PBS-T (310min).
