3.An experimental osteoarthritis induced by implanting composite material into subchondral bone of rabbit knee
Orthopedic Journal of China 2006;0(03):-
[Objective]To investigate the pathogenesis of osteoarthritis by increasing stiffness of subchondral bone to simulate subchondral bone sclerosis to induce the osteoarthritis.[Methods]The proportion between polymethylmethacrylate(PMMA),methylmethacrylate(MMA),hydroxyapatite(HA) and distilled water was adjusted to keep the maximum reaction temperature under 40℃.The composite material PMMA/HA was obtained and compressed on a mechanical material machine to determine its ultimate strength and stiffness,which were compared with those of subchondral bone.The subchondral bone of medial tibial plateau was scraped,where the composite material PMMA /HA was implanted into.Rabbits were sacrificed at 3,6,9 and 12 weeks,respectively.The articular cartilages of the medial tibial plateau were harvested for histological observation.Immunohistochemical analysis was adopted to record the expression and distribution of collagen type Ⅱ and MMP-1 in cartilage at protein level,which were compared with the blank and control groups.Transmission electron microscope was used to examine the ultramicroscopic changes of chondrocytes in blank and 6,12-week-postsurgery groups.[Results]With the time going,the experimental groups gradually presented degeneration,and had increased histological Mankin score.TEM demonstrated degenerative changes of chondrocytes.Collagen type Ⅱ expressed mainly in transition zone and upper deep zone,and MMP-1 expressed predominantly in the superficial and upper intermediate layers of cartilage.Both expressions steadily increased with time passing.[Conclusion]The increased stiffness of subchondral bone induced osteoarthritis in rabbits,which suggests that subcondral bone sclerosis may induce cartilage damage,and that subcondral bone sclerosis is one of the initial pathogenesis of osteoarthritis.

This study was aimed to observe the effect of Danzhi Jiangtang Capsule ( DJC ) on expression of solu-ble thrombomodulin ( sTM ) and soluble endothelial cell protein C receptor ( sEPCR ) in experimental rats of type 2 diabetes mellitus (T2DM). This study also explored possible mechanisms of Yiqi Yangyin Huoxue method on vascular endothelial tissue and discussed mechanisms of prevention and management of T2DM vascular lesions . A total of 60 male Sprague-Dawley ( SD ) rats were fed for one week and then randomly divided into the nor-mal control group ( group N , n = 12 , rats were fed with routine food ) and diabetes mellitus group ( n = 48 , rats were fed with high-fat diet). After 4 weeks, rats in the diabetes mellitus group were injected with strepto-zotocin ( STZ ) to induce T2DM . According to the blood glucose level , rats were divided into three groups , wh ich were the model group (group M), pioglitazone (group P), and pioglitazone combined with DJC (group D). Group P was treated with pioglitazone (10 mg?kg-1?d-1), group D was given pioglitazone (10 mg?kg-1?d-1) and DJC ( 0 . 47 g?kg-1?d-1 ) . The group N and group M were treated with sodium chloride ( 5 mL?kg -1?d-1 ) . After four-week drug administration , the levels of sTM , sEPCR , PT , APTT and FIB in each group were tested . The results showed that compared with the control group , the levels of sTM , sEPCR and FIB in group M , group P and group D were significantly increased ( P < 0 . 05 ) , and the levels of PT and APTT were obviously reduced ( P < 0 . 05 ) . Compared with group P , the levels of sTM , sEPCR , FIB of group D were significantly reduced ( P< 0 . 01 ) , and the level of APTT was significantly increased ( P < 0 . 05 ) . However , there was no significant dif-ference in the increasing of PT. It was concluded that the Yiqi Yangyin Huoxue method can reduce the levels of sTM and sEPCR , and effectively improve coagulation . The possible mechanisms of protective effect on the vascular endothelium can be from reducing levels of sTM and sEPCR in order to enhance the activity of anti-coagulation and fibrinolysis , regulate the function of blood coagulation to improve hypercoagulable state .

AIM: The phagocytotic function and morphological changes of pulmonary alveolar macrophages (AM) of rat in high glucose or high glucose and high insulin conditions were studied. METHODS: AM were harvested from Wistar rats by bronchoalveolar lavage and were activated by Bacille Calmette - Guerin (BCG), interferon a - 2b (IFNa - 2b)or BCG and IFNa - 2b. The adherent rate, nitroblue retrazolium (NBT). reduction function and the concentrations of NO and TNF-a in culture rat AM were evaluated. The ultrastructure of AM was Observed by using transmission elects microscopy and scanning electron microscopy. RESULTS: In high glucose or high glucose glucose and high insulin conditions, the adherence of AM postponed(P< 0.01 ), NBT reduction of AM significantly decreased(P<0.01); the volume of NO and TNF-a produced by AM after stimulation with BCG and IFNa-2b + BCG was significantly lower in high glucose groups than in the controls (P < 0.01); their surface pseudopodia was reduced and shortened and the numbers of Golgi apparatus and rough endoplasmic reticulum decreased. CONCLUSIONS:The impaired phagocytotic function and ultrastructure of activated rat AM were much the same regardless of high glucose or high glucose and high insulin level in a short time. Diabetic subjects were predisposed to infection of the lung, which was frequently recurrent or even fatal.
