ABSTRACT
Abstract?AlM:To compare the effects of different adjustable suture in glaucoma trabeculectomy on early tear film function.?METHODS:Sixty-eight cases of primary glaucoma ( 76 eyes) during January 2012 to June 2014 in our hospital were selected and divided into exposure conjunctival suture group ( 34 cases, 36 eyes ) and embedded conjunctival suture group ( 34 cases, 40 eyes ) according to treatment. Adjustable suture exposed conjunctival suture and embedding conjunctival suture was given to two groups, respectively. lntraocular pressure ( lOP ) before and after treatment 7, 14, 30d were observed and Schirmer test, tear break-up time, No Hikaru sensitivity and the occurrence of adverse reactions after treatment 1, 30d were recorded.?RESULTS: After the treatment, the mean lOP of two groups were decreased significantly ( P 0. 05), after treatment 7, 14, 30d embedded conjunctival suture group was significantly higher than that of exposure conjunctival suture group ( P<0. 05). After 1d of treatment, Schirmer test, tear break-up time, No Hikaru sensitivity of two groups compared no significant difference (P<0. 05). After treatment 7, 14, 30d embedded conjunctival suture group Schirmer test, tear break- up time, was significantly superior to expose conjunctiva suture group (P<0. 05). The 30d package after treatment of conjunctival suture group buried adverse reaction rate was significantly lower than that of exposed conjunctival suture group (P<0. 05).? CONCLUSlON: Trabeculectomy operation with adjustable thread embedding conjunctival suture has few effects on the tear film function in patients with early postoperative complications, lower, and operation effect is better than that of exposed conjunctival suture.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect of Kangxin Capsule (KXC) on the expression of nerve growth factor (NGF) as well as the morphology and amount of nerve synapse in the cortical parietal lobe and hippocampus CA, area of vascular dementia ( VD) model rats.</p><p><b>METHODS</b>The model rats of VD made by photochemical reaction technique were randomly divided into five groups: the model group (MG), the high-dose, middle-dose and low-dose KXC groups (HDG, MDG and LDG), and the Western medicine hydergin control group (WMG). They were treated respectively with distilled water, high, middle and low dosage of KXC suspended liquid, and hydergin for a month. Besides, a blank group consisting of normal (non-model) rats was set up for control (CG). The ultrastructure of nerve synapse in the cortical parietal lobe and hippocampus CA1 area of the rats were observed and its density estimated. The condition of NGF positive neurons in the above-mentioned two regions were also observed by immunohistochemical stain.</p><p><b>RESULTS</b>All the KXC or hydergin treated groups demonstrated a normal amount of nerve synapse with integral structure in the cortical parietal lobe and hippocampus CA, area, which approached that in the CG and was superior to that in the MG. Also, the NGF positive neuron in all the treated groups was much more than that in MG with significant difference ( P<0.01), approaching to that in the CG.</p><p><b>CONCLUSION</b>KXC could elevate the expression of NGF in the cortical parietal lobe and hippocampus CA, area, preserve the number and morphology of synapse, thus to protect the function of nerve system from ischemic injury.</p>

Several specific monoclonal antibodies for B, T and natural killer (NK) cell were used to investigate the B cell localization and the expression of their phe- notype in lymphoid nodules on frozen and paraffin sections of human tonsil and lymph node by means of an immunocytochemical ABC technic. The results indi- cate that monoclonal antibodies reactive with germinal centers in tonsil and ly- mph node gave a simlar results and the results indicate that transformation and germination of germinal center cells involve phenotype changs but except T-200. For example, in the lower zone of germinal center, the lymphoblasts are weakly stained for IgM andLN-2 antibodies, but not for OKB-2 and BA-1, while in th upper zone the centrocytes are intense staining for IgM, LN-2, OKB-2 and BA-1 antibodies arelight or moderate staining separately Further charaterization of B cells in upperzone is frenquently observed clcavages on their nuclear memb- rane. In the mantle zone, the lymphocytes are strongly reacted with OKB-2 and BA-1, middle staining for LN-2 and light staining for sIgM. Plasma cell is only reactive with T-200 and IgM antibodies.
